Research On Chemistry Review Lessons Based On Concepts Construction

Review lessons as an important class type, is of great significance to thedevelopment of students. However, the current review lessons still exist manyproblems. The new curriculum reform advocates the construction of basicchemistry concepts. Using chemical basic concepts to guide the review ofteaching, not only can help students to consolidate the basic knowledge andbasic skills, but also can improve the scientific literacy of students, promote theoverall development of students and make review lessons glow new vitality.On the basis of the overview of domestic review lessons study, the paperdefined and elaborated the contents of review and review lessons, and analyzedthe middle school students should master the basic chemical concepts, coreconcepts and specific knowledge. Based on this, the paper proposed two kindsof teaching ideas and two teaching cases, in order to guide middle-schoolchemistry teachers on theory and practice.The first part, investigated and analysed the current problems of reviewlessons and illustrated the reasons for selecting this thesis.The second part, summarized the overall situation of review lessons study.First, analyzed the overall situation of study on review lessons, includinganalyzing the research trends, topics, strategies and grade distribution. Next,summarized the different content of review lessons. Then analyzed the currentresearch status of chemical review lessons based on the construction of basicchemistry concepts. The third part, putted forward the purposes, methods and train of thought ofthis research.The fourth part, analyzed the characteristics of chemical review lessonsbased on the construction of basic chemistry concepts. First, defined theconnotation of the review lessons. Second, analyzed the psychological activityof the review. Then states characteristics of traditional review lessons andreview lessons based on the construction of basic chemistry concepts.The fifth part, based on the analysis of the middle school chemistry basicconcept, core concepts and specific knowledge, this paper putted forward twokinds of teaching ideas about review lessons based on the construction of basicchemistry concepts.The sixth part, designed two teaching cases respectively according to twokinds of teaching ideas.The seventh part is the problem to be resolved in the next work.The main innovations of this study are as follows: defined the connotationof the review. Analyzed the psychological activity of the review. Statedcharacteristics of traditional review lessons and review lessons based on theconstruction of basic chemistry concepts. Putted forward two kinds of teachingideas about review lessons based on the construction of basic chemistryconcepts and designed two teaching cases respectively.
