A Century of Professional Organization Influence : Findings from Content Analyses of MVTTEC Annual Meetings

Investigating the content presented at annual national conferences is regarded by many as a valid means for revealing patterns within a given professional organization concerning their interests, issues, concerns, priorities, and research foci, which collectively present an opportunity to provide future direction for the organization. As a result, scholars across many different disciplines have conducted such investigations in an attempt to gain insights into their professional organizations (e.g., Berryman, 1982; Conger, 1997; Fetro & Droplet, 1991; Kiehn & Kimball, 2008; Price & Orman, 2001) and provide guidance based on the resultant patterns. Findings from such analyses of conference content are instrumental in documenting patterns relative to past trends within the field, organizational alignment with larger national trends, and using them to suggest future directions for professional organizations. This is particularly effective for investigating those professional organizations that have preserved conference content throughout a long history of annual meetings. In the field of technology and engineering education, the Mississippi Valley Technology Teacher Education Conference, today referred to simply as the Mississippi Valley Conference (MVC) is the oldest continuous conference with an entire century of content available for analysis. From its inception, the intent of this conference was to engage in discussion and debate in order to “help in the solution of problems of great importance” by providing “an opportunity for the teachers and organizers of manual training to get together in close conference where they might exchange their views on questions of vital importance” to the profession (Bennett, 1937, pp. 502–503). The MVC marked its 100th meeting in the fall of 2013, presenting not only a significant historical milestone but also a unique opportunity for investigating the extent to which this individual conference may have influenced the profession as a whole. Specifically, the 2013 meeting afforded the opportunity to analyze 100 years 1 of discussion topics as a means for understanding the significance of the past century of meetings and for the profession to utilize those findings in envisioning a worthy path as they enter into their second century of existence. Such an analysis can reveal whether the conference played a significant leadership role in the midst of educational reform or was just an entity reacting

In the field of technology and engineering education, the Mississippi Valley Technology Teacher Education Conference, today referred to simply as the Mississippi Valley Conference (MVC) is the oldest continuous conference with an entire century of content available for analysis.From its inception, the intent of this conference was to engage in discussion and debate in order to "help in the solution of problems of great importance" by providing "an opportunity for the teachers and organizers of manual training to get together in close conference where they might exchange their views on questions of vital importance" to the profession (Bennett, 1937, pp. 502-503).The MVC marked its 100th meeting in the fall of 2013, presenting not only a significant historical milestone but also a unique opportunity for investigating the extent to which this individual conference may have influenced the profession as a whole.Specifically, the 2013 meeting afforded the opportunity to analyze 100 years 1 of discussion topics as a means for understanding the significance of the past century of meetings and for the profession to utilize those findings in envisioning a worthy path as they enter into their second century of existence.Such an analysis can reveal whether the conference played a significant leadership role in the midst of educational reform or was just an entity reacting to emerging professional issues with discussions simply reflecting the eclectic interests of its membership.Insight might also result from the unique conference venue whereby discussion topics are drawn from suggestions submitted by attending members, which in theory would reflect the majors concerns of the profession.Regardless of outcome, the intent for analyzing the past century of MVC discussion topics is to offer organizational insights that may prove valuable in guiding future directions for both the conference and profession writ large.
Method The research conducted was a content analysis of the discussion topics as reflected in the presentation titles or descriptions listed on the agendas of the annual meetings of the MVC.As with any presentation of qualitative research, establishing the validity of results depends on the trustworthiness of the analytical approach used.To ensure the trustworthiness of results and therefore the validity of research, the methods used are presented in sufficient detail to demonstrate credibility, dependability, and confirmability (Guba, 1981;Patton, 2002).Data were limited to the available archived agendas, both in hard copy and digital formats, for meetings of the MVC between 1909 and 2012.For the purpose of maintaining historical continuity with and avoiding duplication of previous conference topic analyses, elements of both Bawden's 1929 Typical Groups of Topics approach and Lemons' 1988 quasi-objective and interpretive methods were considered, though neither were incorporated.Deliberately distinct from these earlier investigations in both intent and design, this research was designed to ascertain potential relationships between conference presentation topics and the directions of the field over the course of 100 years with consideration given to the contextual influence of major educational reform issues of the times.The research was guided by the following research questions (RQ) and sub-questions (S-RQ).
During the 100 year history of Mississippi to the selection of content analysis as a research design is recognition that in the analysis of latent content, independent coders will subjectively interpret that content based on their own mental schema.It is therefore important to make transparent the coding process and to demonstrate that "those judgments, while subjectively derived, are shared across coders, and the meaning therefore is also likely to reach out to readers of the research" (Potter & Levine-Donnerstein, 1999, p. 266).

Procedures
Although content analysis can vary in its implementation, five general phases recognized as methodological commonalities are followed in structuring the various approaches: composing research questions to guide the investigation, identification and collection of data, outlining and implementing a coding process, definition of applied categories, establishing trustworthiness, and analysis and interpretation of content based on coding results (Creswell, 2014a(Creswell, , 2014b;;Holsti, 1969;Kaid, 1989;Miles & Huberman, 1994;Weber, 1990).The following is a discussion of the various phases followed in the conduct of this research.
Data identification and collection.Conference agendas contained data targeted for analysis in the form of presentation titles or descriptions.The agendas, archived at the University of Illinois, were collected by Life Chair Tom Erekson who delivered one half in hard copy format  via surface mail and the other in digital format (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) via email.A content analysis template was developed by the researcher for entering and organizing the agenda data by year, presentation titles or descriptions, and presenter names.Members of the research team entered data into the analysis template individually with follow up comparisons of all entries to ensure accuracy of data input.
Coding process.To ensure the quality of text analysis, especially with respect to latent content analysis, careful attention must be given to the development, implementation, assessment, and constant refinement of the coding scheme (Creswell, 2014a(Creswell, , 2014b)).Adhering to a broadly referenced qualitative approach for coding data, agenda data were coded following the eight-step protocol (Table 1) suggested by Weber (1990).
Testing of coding on a text sample 4.
Assessment of the accuracy and reliability of the sample coding 5.
Revision of the coding rules 6.
Return to step 3 repeatedly until sufficient reliability is achieved 7.
Coding of all text (using refined codes) 8.
Assess the achieved reliability or accuracy The text from all presentation titles or descriptions was segmented based on the meaning conveyed.Titles often contained segments with multiple meanings, each of which constituted a distinct text segment.Every text segment was assigned a term or phrase reflecting the meaning or meanings of the segment.Those sentences or descriptions relating to the same identified terms or phrases were considered unique text segments and labeled by a code accurately describing the meaning.Approximately 10% of the data were coded independently in this way by individual members of the research team, followed by a comparison and discussion (arbitration) of generated codes.A percent agreement of 53 was calculated as the intercoder reliability for this first coding attempt.The resultant refined coding scheme was then applied to a second similar-sized sample of the data for another round of independent analysis.Comparison and arbitration between the independent coders found the new coding scheme to demonstrate an acceptable level (83%) of intercoder reliability.The new coding scheme was then used to analyze and code another approximately 30% of the data.As before, arbitration was used to reduce and aggregate similar codes into themes and topics, resulting in yet another refinement of the coding scheme.The remaining 50% of the data were then independently analyzed using this refined coding scheme.The coders once more engaged in arbitration to further reduce overlap or redundancy and to achieve the final coding scheme.Using the final coding scheme, one last sweep of the entire data set was once again independently conducted by the researchers, followed again with arbitration on the coded text segments.The final arbitration revealed a total of 1,223 text segments with assigned codes with intercoder reliability approaching 85%.Frequency counts of the coded 1,223 segments were entered into JMP (SAS) software for statistical analysis.

Results
The agenda data reviewed for this research spanned the 104 years in which the 99 meetings of the MVC took place.Over this span of time only five conferences (1911,(1942)(1943)(1944)(1945) were not held.Because the conference was originally designed to be held every other year, no meeting occurred in 1911.The data show there was also no meeting held in 1922, though two were held the following year in 1923 to make up for that missed meeting.An additional four conferences were missed between 1942 and 1945 as a result of World War II.Of the 99 conferences held, agendas for those held in 1919, 1920, 1924, 1933, 1934, 1960, and 1961 (7.07%) were not obtainable for inclusion in this study.The data collected and analyzed in this study were therefore drawn from only the 91 agendas made available to the researchers.

Findings
Review of the 91 conference agendas found a total of 819 presentations addressing a variety of issues.The coding process employed by the researchers was used to identify and organize presentation issues into 7 themes, 27 topics, and 126 subtopics.Figure 1 depicts the approach used in generating specific codes for unique text segments.A full listing of topics and subtopics for each theme, including their associated codes, is found in the Appendix (Tables A1-A7).Table 2, which presents the operational definitions for each theme along with an exemplar text segment demonstrating a meaningful fit with that   (1963).

As previously explained, the scheme used in coding the text drawn from the 819 presentation titles or descriptions generated a total of 1,223 coded text segments.Table 3 presents the resulting frequency counts and distribution of the coded text segments among the seven themes.Analytical Treatment of the Data The overall intent of this research was to discover potential relationships between MVC topics as well as (a) the direction of the field and (b) the major educational issues that arose during the 104-year timeframe.To address these relationships, two main research questions, RQ1 and RQ2, directed the analysis of data.RQ1 required three subquestions; the first subquestion was used to identify major themes, and the others were used to direct data analysis for comparisons between and within those themes.

Theme Identification
The major themes (S1-RQ1), as reflected in the conference agendas, were identified through the organization of tabulated frequency counts of coded text segments (Table 3).A comparison of frequency counts among the seven identified themes revealed relative rankings (Figure 2) by percent totals.As depicted in Figure 2, three themes (Teacher Preparation, Policy, and Epistemology) accounted for 76% of all discussion topics, with 12% attributed to one other theme (Pedagogy).Collectively, the three remaining themes (Research, Conference Evaluation, and Facilities) accounted for the final 12% of topics.

Main Theme Comparisons (S2-RQ1)
Eighty-eight percent of the 819 presented topics coded into four main themes-Teacher Preparation, Policy, Epistemology, and Pedagogy.Given that these four themes comprise the majority of topics addressed throughout the history of the MVC, comparisons between them over time reveal the more significant conference trends and suggested relationships among them.In order to present true relative comparisons among main themes, as well as subtopics within-theme, absolute data were converted to relative percentiles.In doing so, the statistical formula used in generating lines of best fit extrapolates the data in two directions, which results in the left axes for graphs shown in Figures 3 through 8 not representing an absolute percentage, but instead an approximation of the relative percent occurrence relationship.Furthermore, in some instances, extrapolation extends a line of best fit below zero.The overall result, based on relative percent occurrences, presents an accurate statistical comparison between the four main themes, as depicted in Figure 3 in which data analysis is reflected in lines of best fit.

First half century.
When the MVC first began its meetings in 1909, Teacher Preparation was the primary focus of topic presentations (Figure 3), which is logical given the original intent of the conference.Except for the decades between about 1960 and 1980, this theme has remained relatively strong throughout the conference history.However, among the four main themes Teacher Preparation also demonstrated the greatest fluctuations with peaks and valleys occurring about every two decades for the first 80 years of the conference.Furthermore, it is interesting to note that the Teacher Preparation peaks and valleys during this time period were generally opposite to those observed for the other three themes (Policy, Epistemology, and Pedagogy) until beginning its steady rise in the mid-1970s.By comparison, these other three themes trended parallel to one another during the first 40 years, starting with a concurrent general peaking around 1930 and followed by a collective decline over the next 20 years.Around 1950, two of these themes, Policy and Epistemology, begin rising together well into the next century, whereas Pedagogy, those topics targeting issues of practice, declined and persisted at a low level until rocketing steeply upward at about 1990.It is of some interest to note that the peaks and valleys in Pedagogy issues over the first half century of the MVC trended inversely to those for Teacher Preparation issues, which one might interpret as an illogical and unexpected disassociation between the two.Policy issues on the other hand peaked early just before 1920 and then followed a slow gradual decline for nearly 30 years.In the years just prior to and following the Second World War, the lines of best fit indicate a steady decline across all themes for about 10 years.This is understandable, not only because of this global event but also because no data exists for the conferences not held between 1942 and 1945.
Second half century.Toward the mid-1950s both Teacher Preparation and Pedagogy entered into a period of parallel decline, whereas interest in topics focusing on Epistemology and Policy issues began to rise rapidly, a rise that has elevated Epistemology to the dominant issue at the turn of the century.Beginning in the early 1970s and continuing for roughly 30 years, the focus on Teacher Preparation, Policy, and Epistemology issues soared together and eventually converged as equally strong topic areas by the late 1990s.At that point, both Teacher Preparation and Policy issues began to plateau as the MVC turned its attention almost singularly to epistemological issues.Of the four main themes, it is significant to point out that for roughly eight decades (late 1910s to late 1990s), the number of presentations addressing pedagogical issues (teacher practice, design of instruction, and assessment of learning) was consistently one of the lowest by comparison, suggesting that it was of relatively minor concern to the profession.However, upon entering the 21st century, we find a steep rise in attention paid to Pedagogy issues that parallels an equally rapid rise in MVC presentations devoted to Epistemology issues.The rapid increase in attention now being devoted to pedagogical issues is noteworthy in that it marks a historically fundamental shift in conference foci toward issues of classroom practice, which is particularly significant when considering the concurrent context of science, technology, engineering, and mathematics (STEM) education reform in the United States.
The between-theme comparisons among the four main conference themes depicted in Figure 3 expose relational patterns in the peaks and valleys over a 100-year period, as well as unique trends among certain individual themes.A more detailed discussion and interpretation of these relationships within the context of concurrent educational reform movements is addressed later by RQ2.

Within-Theme Comparisons (S3-RQ1)
Investigating the major topical categories within each of the four main themes provides an indication of the variations among the within-theme foci over time and the relative locus of the specific issues addressed.Figures 4, 5, 6, and 7 illustrate such foci variations within the Pedagogy, Epistemology, Policy, and Teacher Preparation themes respectively.The following discussions highlight the observed relationships among the within-theme variations for each of the four main themes (Figure 2), which are presented in reverse rank order by percent.Pedagogy: Within-theme comparisons.Of the four main themes, Pedagogy only accounted for 12% percent (Figure 2) of the total percent of topics presented.And from the degree of fluctuation depicted in Figure 4, at first glance, it might suggest there would be few relationships between the Pedagogy subtopics.However, on closer inspection, interesting relationships can be observed.In particular, there are parallel trends between the Assessment and Theory subtopics throughout almost the entire life of the conference.This might be construed as reflecting connections that underpin the natural relationship between learning theory and the corresponding assessment of student achievement based on that theoretical premise.The data also show an inverse relationship between Instruction and Practice subtopics.This inverse relationship is quite interesting and could imply that there is a significant lag between major periods of curricular development and the necessary concurrent development of the practices required for its implementation.Furthermore, for roughly 30 years, between 1920 and 1950, Instruction subtopics dominated the Pedagogy theme with a sharp peak at about 1930, but then they lost that dominance through an equally sharp decline over the next 30 years.In the late 1950s, data reveal a period of parallel trends among Instruction, Assessment, and Theory subtopics that continues to this day and all of which have an inverse relationship to the subtopic of Practice.The parallels among Instruction, Assessment, and Theory subtopics are to some extent logical when taking into consideration the context of significant and ongoing changes within the field of Technology Education throughout this timeframe (Herschbach, 2009).Of the four major Pedagogy subtopics, it is surprising to find that except for a spike in 1980, Practice was not one of the stronger subtopics of interest at the MVC.
Of particular interest over the past decade of conference meetings is the growing focus on the subtopic of Assessment (of student learning).Attention to assessment, as indicated by the relative percentage of presentations made that related to this topic, begins a steep and steady rise starting in the early 1990s.This trend has continued into the 21st century and today has currently reached a level double that of the previous high point nearly 50 years earlier.From a pedagogical practices perspective as operationally defined for this study (see Table 2), concerns related to assessment of student learning within the design of instruction is on the rise among those topics being selected for conference presentations.This trend is not surprising given the context of educational reform taking place at the turn of the century both within the technology education profession and in STEM education nationally (National Academy of Sciences, and National Academy of Engineering, & Institute of Medicine, 2007;National Governors Association, 2011;National Science Board, 1986, 2007, 2014).steep steady rise in attention paid to epistemological issues every year of the conference reflects a constant and growing concern about what fundamental educational objectives the profession should be targeting.In fact, the data show that among the four main topical themes, presentations related to epistemological issues are without question now the dominant focus at the MVC (Figure 3).
Policy: Within-theme comparisons.The number of presentations coded as addressing Policy issues accounted for 26% of the total (Figure 2) and were categorized into five distinct subtopics.Policy, as operationally defined in this study (Table 2), refers to issues regarding policies relevant to the future direction of teacher preparation programs.From this perspective, comparison of within-theme data analysis among the five subtopics generates an interesting display of the complex relationships that have played out over the century of MVC presentations (Figure 6).When the MVC began in 1909, the top two subtopics were those dealing with Teacher and Program issues, and the lowest three were those concerned with Legislation, State/National, and Forecasting.A century later, we find that State/National and Forecasting subtopics are now the two topical categories of highest concern and that in addition to Legislation, Program and Teacher subtopics are today now among the lowest three.
The Teacher and Program subtopics, referring respectively to those concerning subtopics such as qualification criteria, competencies, and recruitment and those concerning subtopics such as curriculum or content criteria, practitioner standards, and credit transfer (see Appendix, Table A1), were initially the two highest Policy subtopic categories and, throughout most of the conference history, demonstrated more closely aligned trend patterns than any of the others.Policy data indicate that these two subtopics gradually cycle through shallow highs with peaks around 1910, 1980, and between 1970 and 2000; lows with troughs occur in the mid-1920s and again around 1960.Across the conference years, both subtopics continually declined until falling to their all-time lows in 2012.Except for the spike in 1970, the Legislation subtopic (e.g., ADA, Smith Hughes, Vocational Education Act, Federal Aid; see Appendix, Table A1) cycled similarly to the Teacher and Program subtopics but at a much lower level.To some degree, logic can be attributed to the cyclical relationships among these three subtopics considering the influence legislation has on policy decisions.
There is also a close cyclical alignment of trends between the Policy subtopics of State/National, which addresses topical issues such as standards, accreditation, and administrative responsibilities, and Forecasting, which addresses topical issues such as statistical reports and surveys of the field (Appendix, Table A1).The relationship between these two subtopics begins in 1909 where each reflect policy issues of least concern for the conference.In the first decade of the MVC, there is a rapid rise in concern regarding both of these subtopics, with State/National becoming one of the dominant topical issues in the early 1920s.For the next 70 years, the relative percent occurrences for these two subtopics show parallel oscillations but with Forecasting consistently 5 to 10% lower.This relationship changes in the 1980s, and the percent of Forecasting topics escalates during the 2000s to become the dominant Policy subtopic by 2012.The conference period between 1980 and 2000 coincides at the national level with the name change in 1985 from Industrial Arts Education to Technology Education and the publication of the Standards for Technological Literacy in 2000.This is therefore an understandable pattern explaining why Forecasting and State/National are the two Policy subtopics of highest concern during this time period.In contrast, the data show that the Policy subtopics of lesser concern today are those addressing legislation, program, and teacher issues.It is important to note however that the data also indicate that the patterns for the Teacher and Program subtopics demonstrate an inverse relationship to those of Forecasting and State/National issues for which upward oscillations in relative percent occurrence of the former typically follows a peak in the latter.
Teacher preparation: Within-theme comparisons.The Teacher Preparation theme, as operationally defined in this study (Table 2), coded for issues specifically targeting the expectations of graduating preservice teachers, the characteristics of university preparation programs, and the criteria in higher education for those faculty whose responsibilities were to deliver such programs.
By a single frequency count, Teacher Preparation had the greatest absolute number of coded topics (Table 3), accounting for 26% of the total, which is statistically equal to that of the Policy theme (Figure 6).Within-theme comparisons among the four Teacher Preparation subtopics (Figure 7) reveals wide variation in topical foci over the span of the conference years with data indicating that the subtopic of greatest concern centers on Program Characteristics (e.g., planning/redesign, curriculum/content evaluation, disciplinary focus/approach; see Appendix, Table A2).From the first conference meeting to the last, this subtopic has been by far the dominant category of attention among presentations related to Teacher Preparation.Although Figure 7 shows Program Characteristics maintains this dominance over the life of the MVC, as the century passes, it steadily plummets over time and oscillates with some regularity between highs and lows, approximately every 20 years beginning in the early 1950s.The proportionally high level of attention presenters paid to Program Characteristics decade after decade likely reflects the constant challenge of maintaining preparation programs that are contemporary and responsive to market demands.Among the other three Teacher Preparation subtopics, Higher Education (e.g., faculty qualifications, evaluation, recruitment) and Teacher Characteristics (practitioner knowledge, dispositions, and scholarship) demonstrate similar occurrence patterns and change lead positions roughly every 40 years.Furthermore, for the first 50 conference years both of these subtopics maintained a comparatively low level of concern, with upward trends occurring between 1960 and 1970, followed by a steady downward trend at the turn of the century.Given the significance of such characteristics relative to the role of a classroom educator in promoting student learning, it seems somewhat counter intuitive that Teacher Characteristics, the practitioner knowledge expectations of preservice graduates, was not a more prominent presenter topic.This is perhaps not altogether surprising given the typical demographics of the industrial arts and technology educators both in the classroom and in higher education during this time (Wells, 2010;Zuga, 1994Zuga, , 2001)).Up until the turn of the century, the teacher preparation concerns of these educators was traditionally focused on the "doing" and much less on developing the theoretical or cognitive knowledge base that impacts the ability of a teacher to effectively convey content and practice (i.e., addressing the development of student higher order thinking skills; Bouhdili, 1996;Cajas, 2001;Glaser, 1991;Herschbach, 2009, pp. 185-273;Petrina, 2008).
Similar to Teacher Characteristics during the first five decades of the conference, the Higher Education subtopic was a consistently low occurrence topic in the Teacher Preparation theme.Upon entering the 1960s, the percent occurrence of presentations on this topic rapidly increased and rose to its alltime high in 2012.Following a somewhat inverse pattern to the topical trends seen in Higher Education is the subtopic of Graduate Programs.Data show (Figure 7) that, for about the first 15 years, the occurrence of presentation topics directed at graduate programs was the lowest of all subtopics.However, as an integral element of teacher preparation programs, attention to this subtopic steadily rose until, by the mid-1930s, the occurrence of presentations related to graduate programs became the second highest topic in the Teacher Characteristic theme, a position it maintained for about 30 years.Between 1970 and1990, attention to graduate program issues declined sharply, but over the past 20 years focus on this subtopic has enjoyed a gradual rise.The recent rise in attention to graduate program issues may in some way be indicative of the national trend to close undergraduate technology education programs or merge these programs with others such as engineering and the pressure to focus instead on graduate education programs as a means for increasing externally funded research (Akmal, Oaks, & Barker, 2002;Hoepfl, 1994;Volk, 1997;Wells, 2008).

Summary: Topical Relationships and Organizational Direction (RQ1)
Statistical comparisons between identified main themes and the subtopic categories within them bring to light interesting relationships among conference presentation issues and an opportunity for interpretation relative to the direction of the profession at large.Overall, main theme comparisons (Figure 3) indicate a strong relationship between topics focused on the preparation of technology education teachers and policies governing the future direction of programs preparing those educators.These two themes have consistently been the issues of most concern over the entire span of MVC meetings.The level of attention given these two themes steadily rose throughout the conference years to all-time highs at the turn of the century, with periodical changes in lead positions between the two every few decades.A closer inspection of the oscillations between these themes reveals a consistent inverse relationship that can be interpreted as policy informing the direction of preparation programs; a rise in policy topics always precedes a rise in teacher preparation topics.
As a theme of least concern initially, Epistemology was the only one that did not falter in its steady rise over time, and in the last decade, it has been clearly established as the top theme.Set within the context of a profession regularly struggling for professional identity (Herschbach, 2009), the need to establish a sound epistemological foundation for what today is known as Technology and Engineering Education was paramount for guiding that profession.The consistent increase in the prominence of epistemological-related presentations each decade of the conference is an unmistakable demonstration of how the MVC can be seen as providing the profession with direction.
Equally significant in its implications is the lack of attention given to pedagogical issues over the life of the conference (Figure 4).Specifically, for the first 80 years of the MVC, the Pedagogy theme (practices, instruction, assessment, and learning theory) remained the lowest of topical presentations.One might construe this lack of attention as a reflection of a myopic focus on programmatic structure and professional beliefs to the exclusion of developing the necessary practitioner knowledge base required for classroom implementation.The low attention to pedagogical issues at the MVC changed abruptly beginning in 2000 with a meteoric rise to a position now as a dominant topic.This sudden shift is likely a response to the change in pedagogical focus nationally at this time toward overtly emphasizing the need to attend to cognitive connections embedded in the design of instruction and an adequate level of teacher knowledge necessary for its implementation (Cochran-Smith & Lytle, 1999;Bransford, Brown, & Cocking, 2000;Donnovan & Bransford, 2005).That a focus on pedagogical issues is now a significant topical concern at the MVC is another example of how this conference is influencing perspectives and providing professional direction.
The relationships summarized above did not develop in a vacuum and were strongly influenced not only by changes within the profession but equally by forces external to the profession.Specifically, the most significant external forces were the sequence of national educational reform movements arising throughout the past 100 years.Investigating the MVC agenda data in the context of such national educational reform provides an avenue for detecting discernible alignments between topics discussed and concurrent major educational issues during the past century.

Alignment of MVC Issues with National Education Reform Movements
(RQ2) It is beyond the scope of this research to address at a granular level the detailed extent of possible alignments between the MVC and the many educational reform issues arising over the course of a century.Therefore to gauge the extent of influence on directions taken by MVC, it must suffice to investigate potential alignments with only the most significant educational reform movements during this time.As reported at the 95th annual MVC (Wells, 2008, pp. 1-2), over the past 100 years in response to large societal changes, there have been three distinct educational reform movements in the United States: Progressive, Equity, and Excellence (Berube & Berube, 2007).

Progressive Movement Alignments
Beginning in the late1890s and extending into the 1940s, the Progressive educational reform movement, championed by John Dewey and his concept of activity-based learning in school to achieve social transformation, was aimed at achieving whole scale social reform through the promotion of a new liberal education curriculum grounded in a child-centered socially relevant educational philosophy (Ravitch, 2000).This was also a period of rapid industrial expansion that demanded from the educational system "a range of practical and functional subjects that would serve a useful purpose in the emerging industrial age" (Herschbach, 2009, p. 3).Recognizing the value of such practical work as an element of schooling, in 1904, progressive educators, such as Charles Richards, began openly advocating for industrial arts as an instructional approach that made learning content more relevant to students by embedding it in industryrelated activities.Richards and other well-known reformers of the time, such as James Russell, Frederick Bonser, Lois Mossman, and Charles Bennett, continued promoting these progressive approaches well into the 1930s.The teaching and learning issues advocated for by these early leaders in our profession are reflective of the seminal educational philosophy and pedagogical preparation approaches of our field at the time (i.e., industrial arts).It comes as no surprise then to find a collective rise in presentations across all four major MVC themes during the first 30 years of the conference that coincide directly with the timeframe of social reform in the Progressive movement (Figure 8).The data show that midway through this movement MVC, presenters were equally interested in the development of new teacher preparation programs, the epistemological basis of those programs, constructing the necessary policies to support them, and the pedagogical practices needed to implement these new progressive approaches.This interest remained elevated until the advent of the Second World War in the early 1940s and later with the launch of Sputnik in the late 1950s.These two epic global events introduced new social forces that ultimately painted education as a weak link in maintaining the United States as a world power militarily and technologically.As a result, there was a trend in education away from the child-centered curricula "to one that was designed to be much more teacher-centered, with an emphasis on science, mathematics, and foreign language content" (Wells, 2008, p. 2).Beginning in the postwar years and continuing throughout the 1950s, instruction in industrial arts took on an increasingly more technical approach where skill-building objectives were emphasized in lieu of social reconstruction objectives, an evolution that introduced significant curricular uncertainty within the profession (Herschbach, 2009, pp. 27-68).As Herschbach concluded (2009), this was a period of time in which the industrial arts profession was in turmoil with how to redefine itself in the context of social change and position itself as a viable school program.Throughout the 1940s and 1950s, the steady decline in MVC presentations addressing the four main themes (Figure 8) closely mirrors the postwar educational ambiguity and the educational transition period following the Progressive movement.

Equity Reform Movement Alignments
As the country entered the 1960s, a new civil rights era arose as the next large-scale societal force to dominate education in the United States, focusing on inequities within the educational system.Born from this was the Equity reform movement, which was intent on fulfilling the earlier goals of the Progressive movement by refocusing on the child and ensuring an equal education for all.This renewed focus on the child, the passing of key education legislation such as the Elementary and Secondary Education Act (ESEA, 1965), and new innovative programs to educate the poor brought about changes in American schooling that resonated well with an evolving industrial arts profession.Throughout the three decades of the Equity reform movement, the industrial arts profession entered into an extraordinary period of epistemological and theoretical transition (Figure 8) that ultimately led to a fundamental reorganization of industrial arts curricula-one where technological literacy would become the basis for instruction.The effect of this transition is very evident in the MVC agenda data, which show that beginning in the 1960s and continuing into the 1980s, there was a rapid rise in presentations addressing Policy theme topics and a steady though more gradual parallel increase in those dealing with Epistemological and Teacher Preparation theme topics (Figure 8).That policy topics dominated conference presentations is consistent with the intent of the MVC and reasonable given university teacher preparation programs were themselves the main curricular change agents.During this era of programmatic change, an emphasis placed on epistemological and teacher preparation issues would be expected and resulted in both eventually achieving an equally important level of attention to that of Policy.

Excellence Reform Movement Alignments
In the early 1980s, educational reform took on a renewed fervor following the release of A Nation At Risk: The Imperative for Educational Reform prepared by the National Commission on Excellence in Education (1983), which launched the Excellence reform movement.This third and most recent educational reform movement reestablished content at the core of curricular development and focused "all national education efforts on the teaching and learning of content as the corrective measure for solving the problems in schooling created by the first two movements.The content targeted represented a rather narrow band of the overall curriculum placing the primary emphasis on science, technology and mathematics" (Wells, 2008, p. 3).It was during the Excellence reform movement that industrial arts transitioned in name, content, and practice to the field of technology education.As depicted in Figure 8, the top three MVC themes merged at a common high point in the mid-1990s, which directly aligns with the launch of a pivotal initiative by the profession aimed at establishing national standards for technological literacy.As evidenced in the main theme comparison of relative percent occurrences (Figure 8), at this time, issues related to epistemology, teacher preparation, and policy were paramount among the topics being discussed.Most notable from the data is the marked rise at the turn of the century in presentations of an epistemological nature and its climb to prominence as the dominant topic of concern at the MVC.Furthermore, the rise in epistemological topics was closely paralleled by an equally strong increase in topics focused on pedagogical issues.The steep rise in epistemological and pedagogical concerns being discussed at the conference during the first decade of the new century reflects a profession once more challenged to redefine itself in the midst of a new STEM education agenda that was sweeping through the educational system in the United States (Wells, 2008).Persisting with the content focus that defines the Excellence reform movement, the STEM education agenda continues to challenge technology education with competition from the disciplines of science, engineering, and mathematics for teaching technology content and practices.The impact of this new challenge is forcing change, both epistemologically and pedagogically, within technology education in order to maintain its viability as a program area in public education.Responsive to the demands for the profession to change once again, the MVC agenda data document the rise in epistemological angst, along with an equally significant increase in presentations now targeting pedagogical issues.Within the national STEM education fervor, these issues were not only of great concern within the technology education profession but equally so across all other disciplines struggling to address the national call for educational excellence.

Summary of Data Analyses
Thematically, the issues surrounding teacher preparation programs, the policies governing those programs, and their underpinning epistemology have historically been the dominant topics in conference presentations, with issues of a pedagogical nature steadily gaining prominence among them during the past 2 decades (Figure 3).The data also show that in the past 10 years two of the main MVC themes-Teacher Preparation and Policy-though still relatively high, have plateaued and are trending downward as issues of major concern.What is most striking to see however as the MVC completes its first 100 years is that Epistemology is now very much the dominate theme of the current decade, with Pedagogy demonstrating a parallel rise toward dominance.And inferred from an extrapolation of the data, this trajectory is likely to continue into the foreseeable future.
Given that the mission of the MVC is centered on teacher education, it is of significance to note the lack of presentations addressing the analysis of practice from an applied theory perspective.Specifically missing are topics dealing with investigations into the connections between theory applied in practice, for improvement of teacher preparation methods or to validate the disciplinary pedagogy.Both science and mathematics education have addressed these connections between theory and practice quite well over the past 100 years or more, which they disseminate every 20 years or so in handbooks on research in education (Wells, 2010).More recently, investigations into the application of educational theory in practice have become an area of focus in the field of engineering education as well (Wells, et al., 2014;Williams, Gero, Lee, & Paretti, 2010).
Closely related to theory applied in practice is the issue of adequately developing requisite teacher knowledge specific to the technologicalengineering design based learning approach that represents the signature pedagogy of technology education.Here as well is a critical preparation area missing at the MVC: adequately preparing tomorrow's technology educators with 21st century pedagogical knowledge and practices.For example, not discussed are investigations into how preservice students develop any one of the seven categories of teacher knowledge-Content Knowledge, General Pedagogical Knowledge, Curricular Knowledge, Pedagogical Content Knowledge, Learner Characteristics Knowledge, Knowledge of Educational Contexts, and Knowledge of Educational Ends (Shulman, 2003, p. 114)-as they progress through a technology education teacher preparation program.However, over the past 20 years, the agenda data indicate a sustained sharp increase in level of interest toward pedagogical issues (Figure 3).Capitalizing on this opportunity, the MVC could advance a substantive contribution to the profession in calling for presentations on topics such as the behavioral or cognitive premise of our practice, instructional strategies predicated on select theory, or the assessment of practice based on learning theories known to promote desired learning outcomes as a means for providing some direction that promotes maturation of the field.

Conclusions
A definitive answer to the question regarding the extent to which the MVC has been a guiding force for the profession would require a larger more thorough study of the content contained in the actual papers presented.In this analysis of agenda presentation titles or descriptions, it must therefore suffice to but infer from the latent content held within that text any relationships among topics or alignments to the major issues of the times.However, in response to the first research question, the data analysis did identify the most significant relationships both between main themes and within their subtopical categories that produced discernible trends over the course of 100 years.
In main theme comparisons, there is a strong inverse relationship between Teacher Preparation and Policy in which a rise in policy trends precede and are therefore potentially informing Teacher Preparation.The Epistemology theme never falters in its path toward becoming the topical area of greatest concern today and providing a century of discussion that offered direction to the profession.Equally consistent though opposite to epistemological concerns was the lack of attention paid to Pedagogical issues throughout most of the MVC history.However, in the last decade, percent occurrence of presentations addressing pedagogical concerns has risen dramatically, which is an encouraging trend in attention to an area of such importance to the profession.
Significant trends are also seen from analyses of within-theme comparisons across all four main themes.In the Pedagogy theme, an inverse relationship exists between Instruction and Practice, hinting at the lag between curriculum development and the associated practices necessary for its implementation.Conversely, there are parallel trends between Assessment and Theory that allude to the profession's concerns regarding the underpinning connections between learning theory and the assessment of student achievement based on that theoretical premise.Comparing subtopics within the Policy theme shows the low level of concern seen early in the MVC history for State/National and Forecast issues and the high levels of concern for Teacher and Program issues had reversed by the turn of the century.A comparison of subtopics within the Teacher Preparation theme finds that Program Characteristics dominate the issues of concern though steadily trends toward having an equal emphasis to that of the other three subtopics.The dominance of program issues could well be attributed to a constant struggle for programs to remain contemporary and responsive to stakeholder needs.Other within-theme trends of significance are found in the surprisingly low attention paid to both Teacher Characteristics and Graduate Programs throughout the life of the conference.Furthermore, whether between or within main themes, correlations to national education reform movements are evident.
It is recognized that these research findings cannot provide an unequivocal connection regarding the impact of the MVC on the direction of the profession.However, what is clear from the data is that this particular conference has provided an exceptionally unique platform designed intentionally to be responsive to current educational reform and to utilize recognized scholars of the field in an overt attempt to exert influence on the direction of the profession.
