Engaging in Scaffolded Instructional
Innovation
Many successful programs working toward
school mathematics reform include scaffolded field experiences.
That is, opportunities for participating teachers to experiment
with instructional innovation while receiving support. However,
there is great variation in the kind of innovative
instructional experiences that teachers undertake and in the
kinds of support that can be offered. As we examine this kind
of professional development experience we will often refer to
it as “scaffolded instructional innovation.”
Theoretical rationale and empirical support
Research conducted in several areas
supports the value of scaffolded instructional innovation.
First, studies of teachers’ beliefs point out that the
relationship between pedagogical beliefs and practices is not
unidirectional (Thompson, 1992). That is, while teachers’
beliefs clearly inform their practices, we might also expect
experiencing “alternative practices” to challenge
their existing beliefs. This change is especially apparent when
teachers observe their own students demonstrating a higher
level of learning and thinking in non-traditional instruction
than they did in traditional instruction.
The importance of scaffolded field
experiences is also emphasized in Simon’s (1994) learning
cycles model of teacher development introduced in Chapter 3.
Simon identified the planning and implementation of innovative
instruction as a possible catalyst for the fifth and sixth
stages of a teacher’s learning cycle.
At the same time, putting novel
instructional techniques into practice presents a considerable
challenge for most teachers, and many may fail in their first
attempts unless they are supported appropriately. Some initial
scaffolded practice is indeed recognized as a key component in
the model developed by Collins, Brown, and Newman, (1989) to
shed light on the process of learning complex tasks, which we
introduced earlier in Chapter 1.
While it is difficult to evaluate the
effect of scaffolded field experiences alone, many successful
professional development programs have used this strategy
extensively. The changes in teachers’ beliefs and
instructional practices reported by Simon and Schifter (1991),
Schifter and Fosnot (1993), and Borasi, Fonzi, Smith, and Rose
(1999), for example, document the success of combining
experiences-as-learners with scaffolded field experiences.
Furthermore, the latter two studies include case studies and
anecdotal evidence that point to the specific contributions of
scaffolded field experiences.
Indirect evidence in support of
scaffolded field experiences is found in the positive outcomes
reported by projects that implemented one of the NSF-funded
comprehensive curricula (these data can be found in each
project website, listed earlier in Figure 7). These projects
showed long-term gains in student achievement in schools that
implemented these curricula, especially when high-quality
professional development helped teachers use these exemplary
instructional materials appropriately (Russell, 1997).
Illustration 7: A scaffolded implementation
of an illustrative inquiry unit
We derived this illustration from the
Making Mathematics Reform a Reality (MMRR) project described in
Chapter 2. As teachers joined the program, they agreed to
participate in a week-long Introductory Summer Institute and to
implement one of two illustrative inquiry units in at least one
class at the beginning of the following school year.
Both illustrative units highlight
fundamental features of teaching mathematics through inquiry
and present “big ideas” in geometry and measurement
while focusing specifically on the topics of tessellation and
area. A team of researchers and teachers created and
field-tested these units in a variety of middle school
settings. Based on careful documentation and analysis of these
experiences, instructional materials were created to support
the planning and implementation of each unit at different grade
levels and in different school contexts. The materials include
an overview and discussion of the key components of the unit, a
mathematical essay highlighting the “big ideas”
addressed in the unit, a timeline, and selected artifacts
(e.g., hand-outs and assessment tools) from implementations of
the unit in different settings.
Scaffolding teachers’
implementation of these illustrative units began as early as
the Summer Institute. First, participants engaged in two
experiences-as-learners lasting 5 to 7 hours each. The
activities were designed to highlight key components of the two
illustrative units, both of which were adapted to challenge
adult learners. The inquiry on area reported as Illustration 1
in Chapter 4 was one of these experiences. These experiences,
together with the reflection on the mathematical content and
pedagogy that followed, gave teachers a personal understanding
of the goals, rationale and overall design of the two units.
Several participants reported that the positive feelings they
experienced as learners in these inquiries motivated them to
take the risk to try them in their own classes.
These experiences-as-learners were then
supplemented by images of what the two units might look like in
middle school classrooms. Excerpts of an implementation of the
tessellation unit were presented in a 2-hour-long video while a
50-page narrative provided a detailed story of an
implementation of the area unit. After participants watched the
video and read the story, they had opportunities to share their
impressions and to question teachers who had already
implemented the units. Their concerns ranged from the
management of materials and group work to information about
student outcomes and potential pitfalls. Mostly, participants
emerged from these conversations with more experienced teachers
reassured that these experiences could work in middle school
and encouraged by their colleagues’ enthusiasm.
During the Summer Institute, the
facilitators introduced participants to the instructional
materials created to support the implementation of the two
units. Selected readings from these materials were assigned for
homework and later discussed. When facilitators asked teachers
to comment on the value of these readings, they said that
encountering the materials for the first time when trying to
plan their unit would have been truly overwhelming because of
their unusual content and structure and might have easily
discouraged them from using them. Thus, assigning the readings
in the Summer Institute was an important way to enable teachers
to benefit from the instructional materials intended to support
their first field experience.
As teachers began to plan their unit at
the beginning of the school year, facilitators encouraged them
to consult individually with mathematics teacher educators on
the project staff or with a lead teacher at their school site.
Although not everyone took advantage of these opportunities,
those that did found them very helpful. In some cases,
especially when the teacher felt overwhelmed by the novelty and
complexity of the task, these sessions involved brainstorming
and writing an overall plan together. In addition, the teacher
received help writing lesson plans for the first few days of
the unit. In other cases, teachers came to these meetings with
drafted lesson plans that were then discussed and refined. In
all cases, these consultations made it possible to address
teachers’ possible misconceptions and resulted in lessons
that offered much better learning opportunities for the
students.
As teachers began to implement their
units, they could request further support from project staff or
lead teachers. This support usually took the form of classroom
visits followed by debriefing meetings. Whenever possible,
support staff visited classrooms for a few consecutive days in
order to observe how suggestions and decisions made during
previous debriefing meetings played out. The teacher
educator’s role in the classroom visits and the nature of
the follow-up meetings varied considerably, depending on the
personality and needs of each teacher. In most classroom
visits, the teacher educator simply observed the class, moving
around to help individuals and small groups during the lesson.
This strategy allowed the classroom teacher to spend more time
with other students and enabled the teacher educator to report
observations about students’ work and thinking that the
teacher might not have known otherwise. Other times, the
teacher educator played a more direct role in the instruction,
perhaps introducing selected activities, demonstrating the use
of certain materials or recording on the board the key points
of a discussion the teacher was facilitating. In either case,
the debriefing meetings that followed the lesson played a key
role. These meetings focused not so much on providing feedback
on the teacher’s performance, but rather on discussing
students’ work and what had been observed about their
learning and thinking. This kind of knowledge helped teachers
to consider in more depth the mathematical concepts they were
working on and to plan for future lessons.
Occasionally, two or three teachers from
the same school who were teaching the same mathematics courses
worked as a team. In that case, they usually planned the units
together and met regularly to discuss the outcomes of specific
activities and to make revisions to the original plan. These
teams were encouraged to observe each other if possible, but
few managed to put this suggestion into practice.
Finally, in November, after everyone had
concluded the implementation of the first inquiry unit, all
Summer Institute participants were called back together for a
day-long meeting. To prepare for the meeting, teachers were
asked to look back at their experience and to identify at least
one success and one concern that they would like to share with
the rest of the group. The meeting began with each teacher
briefly sharing these reflections.
Overall, the reports were quite positive,
and in most cases, even enthusiastic. Most of the successes had
to do with student accomplishments; several teachers reported
their surprise at seeing some of their weakest students blossom
during this unit and reveal abilities they had never imagined!
This sharing also revealed some common
concerns and challenges. Several teachers reported feeling
panicked when students came up with solutions they could not
understand or questions they had no idea how to answer. Others
were worried about being able to follow through, given the
enormous amount of time and energy this way of teaching
requires. In the second half of the meeting, these common
concerns were addressed in small groups. While the small groups
did not always reach satisfactory solutions, teachers generally
agreed that it was helpful just to know that other people had
encountered similar problems or worried about the same issues.
