High School Chemistry Teaching Structure Of The Core Concepts

The teaching structure is an important basis for the implementation of effective teaching, and reflects the teaching philosophy and instructional design capacity of the teachers. The research of teaching structure becomes a hotspot of the basic education curriculum reform.The thesis chooses’preliminary discussing on core concept of high school chemistry teaching structure based on the chemistry video case studies’as a research subject. It explores and discusses the definition, connotation and teaching characteristics of the teaching structure, and video case studies and other theoretical basis. It designs coding system of the core concept of high school chemistry teaching structure. It selects23outstanding teaching video cases covering five different core concepts; uses the coding system of the core concept of high school chemistry and the software of anglicizing event sampling and time sampling teaching video for quantitative research and data analysis; builds two different dimensions of teaching structures; analyzes class teaching characteristics of high school chemistry core concept based on obtained teaching structural.The class teaching of high school chemistry core concept with the following characteristics:concept teaching based on two-stage:the stage of information processing, understanding and concept of initial formation, and the stage of the concept contact and integration; during the first stage the behavior of lecturing, driving and operating works simultaneously; during the second stage the behavior of lecturing and driving goes simultaneously; teacher’s behavior is the main activities of the class teaching; lecturing behavior occupies a large proportion in the class teaching; class teaching pays attention to experiments and media applications; students participate in the class more and have a greater space to think; the teachers control the class well.The study also puts forward suggestions for teaching:to pay attention to cultivating students good learning habits; pay attention to controlling the class harmoniously; creation of teaching context should be run through class teaching; should pay attention to the development of experimental content. At the same time, research also shows that the teachers’personal styles, knowledge structure, students’ level of development are important factors of the core concept of high school chemistry teaching structure.
