Research On Secondary Development In Teaching Materials Of Chemistry For Junior School

A new round of curriculum reform has upended the position of absolution and authoritarian in the traditional education, textbooks no longer are simple carrier of knowledge, but an important curriculum resource, teacher no longer is also sole user of textbooks, but curriculum resource developers with right and responsibility to develop the teaching materials. The new curriculum reform advocates students’ development as the foundation; chemistry teachers should consciously and autonomously carry on the secondary development of textbooks, which makes the teaching materials better suited to the requirements of education and teaching. Under the conditions that the current literatures are less for secondary development of junior school chemistry textbooks, the author researches provides some methods for how to make the secondary development of teaching materials basing on the contents research of junior school chemistry textbooks, in order to better assist teachers to make full use of the secondary development functions in teaching materials.Some references have been cited in this paper, which based on the study of relevant literatures about the secondary development of the materials and concluded the connotation and the previous work of the secondary development of textbooks. The constructivism and paradigm theory are used as instructions, and the principles of the secondary development are scientific, practicing, combining with the times and the development of science and technology, and taking students as the center in education process. Meanwhile, the literature research method, interviewing method and the education experience summary method have been applied in studying the secondary development method of teaching materials for junior school. These development methods are mainly focus on the additions and deletions of the teaching material content, replacement, appropriate adjustments on teaching sequence, flexible use of teaching material content, and deep excavation of education values of chemistry teaching materials for junior school and so on, and some example cases are given. Aims are to provide the chemistry teachers with the basic ideas and methods in secondary development of teaching materials, to make the teachers understand how to deal with the materials in the secondary development, and creatively, novelly and enlighteningly to provide the teachers with solutions to make the knowledge structure of original teaching material system changing, which based on the active secondary development of chemical subject thought, was helpful to guide the teachers to change from “teaching materials’ ’ to “teaching by using materials”, and helped teachers really realize good use of teaching materials. It is not only an effective way to improve the teachers’ professional level, but also can satisfy with the needs of students that teacher makes the secondary development of chemical materials, in order to make sure the subject position of students in secondary development of chemistry teaching, to promote students’ level of using textbook knowledge, and to improve understanding level for academic ideas, which should be guided as courses’ standard under the correct understanding of materials, at the same time, fully thinking of teachers’ teaching ability, the knowledge level of students, the outside environment, and other factors.
