Research On The Design Of Chemistry Teaching Situation Based On Lesson Analysis

The general high school chemistry curriculum standard emphasizes the actual problems in teaching practice,promoting students' deep learning and cultivating the core literacy of chemistry.How teachers design and apply teaching situations is an important research topic in teaching practice.This paper synthesizes chemistry teaching situations related researches,constructing the evaluation criteria of excellent chemistry classroom teaching situations.This paper takes chemistry teaching observation class at thirteen high schools in Dalian and at one in Qingdao as the research object to analyze,where the video lessons were transcribed into texts by video transcription method,the functional and composition features of teaching situations were showed,and the ways of presenting from the teaching situation were presented.A study of ten chemistry teaching observations found that most of the chemistry observations have different types of teaching situations and presentation methods,and the teachers mostly focus on the functional characteristics and constitutive features of the situation.This can help students understand new knowledge and apply chemical knowledge to a certain situation.Students then can understand core concepts of science or scientific methods through certain events,including the core chemical issues to be solved,where they may gain a certain direction.However,teachers should pay attention to the actual situation throughout the teaching process.They should also provide a framework for students to communicate and participate in learning specific chemical topics,strengthening the connection with the practice.The study of two groups of peer-to-peer classes has found that the same topic taught in different methods can create different teaching situations,where the functional features and constitutive features can be different as well.Each teaching situation has its special presentation mode and type.This requires teachers to create a reasonable teaching situation according to the characteristics of each class.Based on the analysis of the above examples,the strategies of chemistry teaching situation design are summarized from the aspects of chemistry teaching situational features and constitutive features,situational orientation,positive aspects and diversity.
