Practical Research On Pre-assignment Of Chemistry Review Course In Junior Middle School

The efficiency of chemistry classroom teaching in junior middle school has a great influence on students' learning efficiency.The efficiency of chemistry review class in junior middle school is particularly important.Chemistry review class in junior middle school is not only an important stage of summarizing knowledge and understanding sublimation,but also plays a vital role in promoting students' knowledge structure and application.Therefore,it is very necessary to explore the pre-assignment of chemistry review course in junior high school,which can lay a theoretical foundation for the follow-up teaching.Through literature,we can understand the current situation of research in related fields and search for important theoretical research.Secondly,compile student questionnaires and teacher interview outlines,fully investigate the current situation of junior high school chemistry review class learning,analyze and collate the survey data,take the survey results as the design basis of the pre-assignment,and try to solve the current problems in teaching,focusing on the design requirements,design strategies and testing and evaluation of pre-assignment design and research.Applying the designed pre-assignment design of chemical review course to the actual teaching,the results show that the application of the pre-assignment of chemical review course can obviously improve the participation and review efficiency of the students in the junior middle school chemical review class,promote the students' autonomous learning,and guide and cultivate the students' integration through the pre-assignment.To improve students' ability of learning and communication,to promote students to build a framework of chemical thinking and enhance their ability of chemical thinking.
