Development of Preservice Biology Teachers’ Skills in the Causal Process Concerning Photosynthesis

Arzu Saka


Photosynthesis is the most effective cycle and sustainable natural process known in nature. Students who learn the subject of photosynthesis well will also make better sense of other issues such as environmental problems, the state of the atmosphere, greenhouse gases, climate changes, carbon footprints and conservation of forests. The aim of this study is to present an example of a worksheet that investigates the skill levels possessed by preservice teachers’ in the causal process, and also to examine their ability to write a photosynthesis equation by means of a history-based approach that also includes reading skills. The study was conducted with the action research method. The study sample consisted of a total of 71 preservice biology teachers. At the first stage, before the implementation of the worksheet, 34 teacher candidates from within the sample were asked a question with a diagram summarising the photosynthesis process. At the second stage, all the prospective teachers were asked for the skill levels they possessed in the causal process to be assessed via implementation of the worksheet. The answers given by the preservice teachers in the defining variables section in particular make up the least answered section of the worksheet. In the section of the worksheet related to making inferences, The students were asked to write the four separate equations by revising them incrementally, and it is striking that the rates of correct answers given for each were high. There is a need for teaching materials to be designed in the field of science at university level and for these to be made available to science teachers in book format.
