Using The Learning Cycle To Teach Chemistry In High School

In this paper, the learning cycle was used to teach chemistry in high school; the origin, phases, types, development and theoretical foundations of the learning cycle were discussed; some cases of learning cycle teaching were sumed up; the applications of learning cycle in science teaching were reviewed. The learning cycle is mainly used in concepts learning and teaching, so more than one thousand students were investigated, to seek the learning conditions of chemical concepts. Using learning cycle method, lesson plans were developed, and put into practice for one month.This research revealed:1. With the help of learning cycle, students can learn chemical concepts by inquiry approaches.2. The learning methods of students who participated in the research were improved, but no significant differences.3. The students who participated in the research basically met the teaching requirements, especially did well in the key points and the difficult points.4. The feedbacks of the students who participated in the research were pretty good, with one or two exceptions had some negative attitudes.5. The difficulties in learning cycle teaching included the teaching time and teaching progress, cooperative teacher's understandings to learning cycle, the adjustment of students who participated in the research, and the shortages of experiment devices. Some suggestions were given to solve these difficulties.
