A Research On The Teaching Strategy Of Physics Unit Review Lessons In Junior Middle School

Teaching strategy is defined as a series of teachers'teaching behaviors to achieve instructional objectives in a specific context. It can effectively increase the teaching efficiency and complete teaching tasks better to developing and selecting appropriate teaching strategies.Existing studies on review teaching are analyzed by documentary analysis. The research of teaching strategy of physics unit review lessons in junior middle school is proposed to solve existing problems.According to common teaching methods of physics unit review lessons,5 teaching strategies are proposed:①lecture strategies, including using logical speeches and repeating rationally;②discussion strategies, including giving materials on discussion, indentifying topics and maintaining by questions;③exercises strategies, including choosing exercises, assembling exercises and method guiding about solving problems;④experiment strategies, including training the use of basic equipment, improving students'interest and developing abilities of solving practical problems;⑤chart strategies, including demonstrating knowledge system, showing the process of thinking and making quantitative relations clear. At the same time, how to use these strategies is explained by practical cases.According to influencing factors on teaching strategy, the influence of instructional objectives and students'performance are elaborated through case study.Finally, unit review instructional design of "Density and Buoyancy Force" is made by these strategies. Practice proves that teaching strategies of physics unit review lessons in junior middle school possesses feasibility and operability. When choosing strategies, teachers should also consider his features to choose his adept strategies. These strategies should be combined in practice.
