Qualitative data analysis revealed that student learning was related
to the instructional practices and modifications used by the teachers.
Changes from the pre-assessment to the final assessment indicated
that students had demonstrated growth in science learning and
that they met the goals of the science units. Teachers acknowledged
that the Action Reflection Process guided them to focus on ensuring
that students understood a few goals of the science unit, rather
than covering all the concepts in the unit. When the student work
indicated that students did not understand major science concepts,
teachers devoted more time to those concepts. For example, the
goals of the fourth grade Astronomy unit are that students will
use outdoor observation and the astronomy labs to investigate
shadows and to model the changing relationship of the earth and
sun from day to night and from season to season. Students learn
the following concepts:
-
Outdoor shadows change predictably in length and direction during
the day.
-
Night
occurs when the earth rotates through its own shadow.
-
The shadow of the earth changes in a predictable way and accounts
for the seasons.
Through
observing student work, teachers learned that students were having
difficulty learning the first two concepts of this unit. Therefore,
the teachers used strategies and modifications to teach these
concepts more thoroughly, spending time on them until they felt
that students successfully demonstrated their understanding. Consequently,
students developed a deep understanding of what causes day and
night and how shadows change, rather than a superficial understanding
of all the concepts in the unit.
Through
looking for evidence in student work that demonstrated whether
students understood or didn't understand the concepts, teachers
determined how they needed to modify their teaching, what adaptations
students needed, and how to measure student understanding. They
developed assessments that provided students with opportunities
to demonstrate their knowledge through multiple modalities. They
made comments such as this:
"He
does have the concept of what causes night and day because when
you look at what he has written for number two on that same
page, he writes, 'When the sun is facing Asia it is day, but
on the other side the moon and stuff are facing us. So that
makes night for us.' His drawing is confusing, but what he has
written demonstrates better understanding of the concept than
his drawing. When you connect the two, then you definitely see
his understanding of the sun and the rotation of the earth and
his understanding of the concept of night and day."
Teachers
collaborated to support one another and develop a more unified
curriculum. The social studies teacher responded to the teacher
comment above:
"I
see some connection to what we were doing in social studies,
because we were really working on math and globe skills last
term. Especially the concept of the globe and what was on one
side and what was on the other."
Teachers'
remarks about student progress were now grounded in evidence.
In one group, where students had been exploring the properties
of liquids, a teacher remarked, after looking at the work:
"All
three [students] seem like they have some of the big picture
of this liquid and of liquids in general. [They list] properties
such as thickness, heaviness, and stickiness. This seems to
be common to all of them. So, I think that shows good evidence
that they know something about this liquid."
At
the end of each session, teachers compared students' pre-assessments
to the final assessments and documented changes in students' understanding
of the concepts. The science curriculum specialist, who had been
present at many meetings, commented:
"The
students have learned more in science--they wrote more, drew
more, and labeled more. They seemed to gain ownership of the
science language and some science ideas."
Indeed,
this was supported by the statistical data, which indicated that
all students, including students with disabilities, gained this
ownership of science language and science ideas at approximately
the same rate.
