To Promote The Concept Construction Of The "elements And The Material World" Unit Teaching Research

Comprehensively implementing the training of chemical basic conceptionis beneficial to comprehensively improve students’ scientific literacy, and playsan irreplaceable role in the development of the students and the community. Assuch, in the teaching of chemistry, paying attention to the basic conceptconstruction of chemistry is of great theoretical and practical value.The arrangement of the Luke version for the textbook pays attention topromoting the concept construction. This study was based on the theory of theconcept construction, to analysis the unit "element with the material world" ofthe Luke version for chemistry (compulsory one), and to mine the basic conceptscontained in the textbook, then to promote the concept construction as the coreof unit instructional design, this will help students construct concept.Thesis includes the following seven sections:Part one, to present the reasons.Part two, summary of existing researches includes teaching theories ofchemical basic conception, studies of unit teaching and the teaching studies ofelement with the material world. First of all, the summary of existing researchesmainly includes the basic concepts of chemistry teaching construction designideas and theories of unit instructional design about chemistry, it providesinstructional design ideas for this study. Secondly, the summary of the existingteaching research about elements of the material world provides inspiration forinstructional design of this article.Part three, to indicate the purposes, missions and research methods.The forth part builds unit instructional design model to promote the conceptof construction, and elaborates connotation of the model.Part five, based on the concept construction of element and the materialworld unit teaching design. In this section, according to the conceptconstruction unit teaching design ideas, this study analysis respectively element and the material world teaching content, excavate the basic idea,Part six, the practice of research and detection results. We carried out theteaching design of Element and the classification of substances, Colloidal, andthen detected and analysis on the effects of teaching, to test the effectiveness ofinstructional design.Part seven, conclusions and prospects. Of this study summarize theconclusions. At the same time, to analysis the shortcomings of this study, inorder to provide a basis for follow-up study.
