The Practice Research Of Sub-Classroom Teaching Mode In Junior Middle School Chemistry Unit Review Lesson

The PAD class is a kind of teaching mode which divides the class time into three parts:intensive lecture,internalization absorption and communication discussion.In response to the requirements of teaching reform("double reduction" policy)on the quality of homework design and teaching quality,it is necessary to ensure that students study well in school.Combining with the present situation of chemistry review class in middle school and the advantages of applying PAD class teaching mode to review class,PAD class teaching mode is applied to chemistry unit review class in junior middle school,in order to improve the current situation of chemistry review class in middle school and improve students’ academic performance,learning interest,teamwork,communication and autonomous learning ability.Through the literature research method,this study understands the research status of the teaching mode of PAD class,clarifies the entry point of the teaching mode of PAD class and the review class of junior high school chemistry,and clarifies the research purpose and significance.Define and extend the concept of PAD class teaching mode,learning cognitive theory,constructivism and other guiding theory,clear the teaching process and principles of PAD class teaching mode.Select the People’s Education Press junior high school chemistry first unit’into the chemical world’,the second unit’we surround the air’ and the third unit’material composition of the mystery’ three unit content for teaching case design,and in a junior high school in Tongxin County,Wuzhong City,two parallel classes for teaching practice.Before the practice,the PAD class teaching mode was introduced to the experimental class students for the smooth implementation of teaching practice.After practice,the results of students’ internalization absorption homework,unit test scores and questionnaire survey are analyzed to test the improvement of students’ performance and ability by PAD classroom teaching mode.The experimental results show that the application of PAD class teaching mode in junior high school chemistry unit review class is effective.From the questionnaire,students’ interest in learning has been improved,their learning attitude has been improved,and the PAD class teaching mode has a high evaluation.From the effect of unit test,most students’ chemistry scores have been improved.From the grade evaluation of students’ internalization absorption homework,it is found that most students have good knowledge,and students’ learning autonomy is improved from the completion rate of homework.From the perspective of classroom performance,students’ teamwork and communication ability have been improved.Therefore,this study will be divided into classroom teaching mode applied to junior high school chemistry unit review class has certain practical value,so as to provide teaching reference for middle school chemistry review class.
