Rapid-Cycling Brassica rapa를 이용한 창의력 및 과학적 사고력 향상을 위한 광합성 실험 모듈의 개발

Abstract

This study aimed to develop a photosynthesis module to enhance the creativity and scientific thinking of secondary school students. Based on our previous research, the theme 'light intensity and photosynthesis rate' was thought to be the best by many secondary biology teachers which may greatly enhance students' creativity and science thinking. New photosynthesis module, 'How can we float leaf discs?' was developed according to the Learning Cycle Model using Rapid-cycling Brassica rapa (RcBr). It consists a series of activities to make a hypothesis and to design an experiment to solve the questions generated by the students themselves. It has two major inquiry activities, and the first is "Why do the leaf discs float?" and the second is "What is the best condition to float leaf discs?" In addition to them, it also presents important sections for the advanced learning, application, formative evaluation and reading material. The 20 experienced biology teachers from every province in Korea were invited to the special workshop held to determine the feasibility of this module. After practicing with it, they had evaluated it to be positive, as a new strategy to make students enhance their creativity and scientific thinking. And they thought this is different activity from ones included in the old biology textbooks. They concluded that it could be applied to the secondary school biology classes with success to attain our goal.
