To Improve The Review Of The Chemistry Knowledge Structure Formula In Grade3

Knowledge structure formula is a concept that the learned essential knowledge is combinedwith each other according to the interaction, mutual contact and order and simplified fromcomplication, which helps students to produce visual feeling and the understanding to theknowledge system and structure. Nowadays, the further research on the system of chemistryknowledge structure of Senior High is less, therefore, I choose to explore the strategies onpromoting knowledge structure formula and knowledge representation in the review of chemistryknowledge of Grade3and try to provide reference for the effective review in the chemistryteaching in Grade3, which is bound to be guided by modern learning theory and the newcurriculum teaching idea.This thesis consists of seven parts.The first part raises problems and the research significance. In this part, the necessity ofhigh school knowledge structure formula in teaching is advanced from the feature of chemistry,to cultivate students’ ability in learning and to enhance students’ results of reviewing.The second part is on the domestic research actuality. On the basis of referring todocument papers and knowing the existing research results in theory and practice, the newresearch direction can be put forward.The third part involves the purpose, idea and approach.They are briefly elaborated. Andmake more explicit purpose of the research and expectations of the implementation of theprocess.The fourth part is about the theoretical basis of research. In this part, the study on the waysof presenting structured knowledge and the strategies in the review of the chemistry knowledgeformula in Grade3is put forward, which is based on constructivism theory, schema theory andsubject structure theory.The fifth part deals with the implication of high school chemistry knowledge structureformula in teaching. The difference and conversion between chemistry knowledge structureand the cognitive structure are illustrated; the strategies in the review of the chemistryknowledge structure formula in Grade3is raised and the way of presenting structuredknowledge is summarized and teaching cases are designed on the basis of practical teaching.The sixth part is about teaching practice in the review of the chemistry knowledge structure formula in Grade3, using element compounds as an example. In the first part, analysis theknowledge structure of all elements and their compounds in the textbook and make a explicitrequirements in examination syllabus and the goal in the review; In the second part, which isabout the teaching practice, combine the knowledge and concept of element compounds withsocial production and practice in life and experiments, carry out structured teaching and focus onthe application of the strategies in knowledge structure formula and the teaching effect in thepresentation of the structured knowledge; The third part is about the reflection on teaching. Theteaching of structured knowledge is beneficial to students to understand, memorize and applychemistry knowledge, but there are still some problems, which should be awarded of.The last part is related to discussion and prospects. In this part, the significance of the studyshould be acknowledged and on the other hand some problems also exist. Looking forward tomore teachers and experts can pay close attention to the review of the chemistry knowledgestructure formula in Grade3, do more exploration and practice and deepen and improve theapplication of the review of the chemistry knowledge structure formula in Grade3.
