an innovative approach

students’ own views about plants as a basis of correcting the misconceptions, and to
develop friendly relationships between the teacher and student, and student and
student. She also facilitated students’ argument in discussion, and promoted
classroom participations for students valuing in classroom study. As the results, the
students were found to be confident of the participation. They also could develop the
understanding based on the new teaching unit by themselves.
On the other hand, the teachers who emphasized teacher-centered approach
and perceived the student role as a passive learner rarely appeared to regard on the
learning culture and participation. Teaching often focused on lecturing abstract
photosynthesis concepts to cover all contents for taking the examination. The
students did not appear to prefer the teaching. For example, S05, the student in Mr.
Vyn’s classroom addressed that “It seemed to me that no problem solving in our
class…there was just studying death knowledge…” Also, S12, the student in Mrs.
Amp’s classroom, was going to study biology with the private tutorial institutes with
her perceptions that the classroom teaching could not convince her for taking the
National Entrance Examination.
Up to this point, the Chapter V illustrated many findings of the
implementation and impacts of the photosynthesis teaching intervention. The
summary of this Chapter V has been presented below.
Summary
This research conducted three case studies of the teachers. There were one
hundred and eighteen students being taught using the photosynthesis teaching
intervention. Twelve of the students were in-depth studied. The studies concerned
their progress from the introductory knowledge about photosynthesis to the advanced
knowledge and their views about the teaching intervention. The findings illustrated
that teacher’s belief of student learning, content knowledge, roles of teaching and
formative assessment impacted on the teachers’ implementation. The teachers who
believe in constructivist approach, have strong contents and regard to Thai socio-
