Table 4.1 Cont’d Lesson 7. A cam paign: photosyn thesis for envi ron ment Periods (min) 1 (50) plus Outside teaching period Learning outcomes Concepts Students would be able to… 1. tell the story of the relationship between photosynthesis and environment 2. apply photosynthesis knowledge to conserve the environmental issue in school or community. 3. explain the advantages of cooperative working. 1. Photosynthesis essentially decreases CO2 in atmosphere causing the green house affect resulting in higher temperature of the earth. 2. Plant photosynthesis releases O2 for respiration of all oxygenic living things. 3. Photosynthesis acts as an intermediary which changes light energy to chemical energy, in terms of food for every living thing. Learning Activities 1. Science project 2. Students’ personal story telling 3. Group work 4. Classroom discussion Materials Assessment 1. The work sheet: A campaign to conserve the environment by photosynthesi s 2. The presentation board in the discussion 122 1. Use the work sheet: A campaign to conserve the environment by photosynthesis to evaluate the students’ proposal about the science project 2. Use classroom discussion to evaluate the students’ applying the photosynthesis knowledge to conserve the environment. 122
After the researcher finished developing the photosynthesis teaching unit, three participant teachers were invited to participate in the meetings. Those aimed to introduce the teaching unit and its guiding principles to those teachers. Then, the teachers were challenged to recognize the students’ misconception using empirical data of the Introductory Photosynthesis Survey (IPS). The survey showed their students’ learning difficulties of photosynthesis. The teachers were expected to be able to adapt the unit for the student needs and the classroom society and culture. Summary The six guiding principles of the photosynthesis teaching intervention had been developed to scope for developing the photosynthesis teaching unit. This 123 included seven lesson plans for twelve 50-minute teaching periods. The understandings of photosynthesis in its relation to nature of science and environment would be enhanced using the generative learning model of teaching. Teaching would focus on correcting the students’ misconceptions about introductory photosynthesis using think pair share, game and discussion. Then, the students’ understanding of photosynthesis integrated with nature of science teaching would be challenged using several learning activities such as experiment, concept mapping, cooperative learning, discussion and role play based on historical discovery of scientists. Also, teaching would promote students’ application of photosynthesis knowledge. The students would relate the knowledge to conserve the environment through problem solving and science project. Along time of teaching, teachers should concern students’ learning society and culture: living style, views about plants and educational value to adapt the teaching intervention for students’ needs. Also, teachers should encourage students’ participation in learning activities to facilitate teaching based on the intervention. Next is Chapter V. The implementation and impact of the teaching intervention in the three biology teachers have been described as three case studies.
