Teaching Design And Implementation Of“Primary Battery” Based On Chemistry Subject Comprehension

The knowledge of primary battery is the important content of middle school chemistry, and also one of the difficult points of chemistry teaching. In the teaching process, we find that not only students but also teachers are often confused with it.Teaching design is based on the need to solve the problem of concrete teaching, so a sophisticated primary battery teaching design is particularly significant. In order to improve the effectiveness of primary battery teaching, this research has mainly done the following work:In the process of basic research, the author first expounds the domestic research status of battery teaching, and then expounds the development of foreign research,from three aspects of time, characters and the main events, so as to make a deep comprehension for recent research situation of the primary battery and the problems existing in the teaching.In the process of bracing research, the author first defined the central concept of subject comprehension and chemistry subject comprehension. Secondly, according to the students’ cognitive level and textbook writing ideas, the primary battery knowledge was divided into five levels and four types, and built the pyramid model to make them fully integrated. Finally, to master the central knowledge of primary battery and reflect the method of this subject thinking, the research interpreted this model.In the process of the core research, the author first made the teaching design from the perspective of chemistry subject comprehension, then designed the questionnaire of this study and implemented it.According to the results analysis of the questionnaire, the primary battery teaching design, based on chemistry subject comprehension is effective, which not only makes teachers and students set up the basic chemistry concept, and promotes students the way of thinking and problem solving skills, but also breaks the primary battery teaching difficult points and helps students get over the learning difficulties.
