The Study Of Insturctional Design For Chemistry Exercise Lesson Of Senisor Middle Schools

The task of exercise lesson is to help students to build thinking platform, clarify the context of knowledge, improve the cognitive structure and to form a comprehensive ability. To design a good chemistry exercise lesson in high schools and shall be implemented is an effective way to mention the efficiency of chemistry teaching.The thesis starts with the analysis of current situation of chemistry exercise teaching at the phase of senior education.We haue used interview research method and questionnaire,.Then through visit those chemistry teachers of eight senior high schools'in Zhejiang Province.,the study finds there are several teaching problems as follows:the teaching aim is fuzzy and capricious, the selection of teaching content is blindness, the teaching strategy ignores practical operation, the process of teaching ignores the subject sexual of students, teaching evaluation ignores encouragement and guidance. These problems make clear that the level of many chemistry teachers'instructional design is not very good. According to these problems, this study proceeds the education theory that "all is for students'development", based on the the existing research of instructional design and chemistry exercise teaching, with the guidance of "zone theory" and constructivism theory, according to the characteristic of chemistry, then put out the principles and process mode of the instructional design for chemistry exercise lesson. Based on the constructed process mode of instructional design for chemistry exercise lesson, the paper studies the links of instructional design in detail. It involves the following components:instructional objectives analysis, design of chemistry exercises, front-end analysis, design of exercise solving teaching process, design of instructional evaluation and evaluation of instructional design. The research also affords the concrete cases to display and revise the proeess of design.Research on instructional design of chemistry exercise lesson is a system engineering. And it is a long-term employment that requires broad participation and efforts of workers in chemical education. The content of this paper is hope to promote chemistry teachers to renew their teaching principles, improve their instructional design and teaching quality of exercise Lesson. At the same time, the thesis is hope to promote further study of instructional design for chemical exercise lesson of senior middle schools.
