an innovative approach

Therefore, this research suggested that teachers should receive enough
opportunities to reflect and share teaching experiences with other teachers within the
department and with the school. The resulting reflection would probably help the
teachers to be aware of and to accept the need for professional development. Then,
they might be convinced to change their teaching practices. In addition, people
concerned with teacher development might need to promote the teachers’
understanding of both scientific content and of the nature of science. The school
should emphasize the value of teaching as the teachers’ main function. Teachers
should be allowed enough time to prepare their lessons. Interviews with teachers also
indicate that teaching periods should not be interrupted by school events.
This thesis has illustrated how three biology teachers from different high
schools have taught to promote Grade 11 students’ understanding about
photosynthesis through its relation to the environment and the nature of science.
Also, the thesis has provided results from different teaching. The teaching based on
social constructivist belief of learning and Thai social context appears to result in
better acquisition of knowledge. Correcting students’ prior misconception appeared
to support enhancing students’ understanding of advanced photosynthesis.
Encouraging students’ participations in learning activities especially discussion
appeared to promote interactions between teacher and student as well as student and
other student. Therefore, the main resulting issue is to see how the teachers should be
encouraged to teach using these ideas.
