Basic Concepts Classification Of High School Chemistry And Instructional Design Practice Of Meaning-Construction

The basic concept is one of the main chemical components of high school chemistry curriculum and plays an important role in the high school chemistry education. Studying the basic concepts of chemistry teaching, improving the efficiency of teaching the basic chemical concepts, is an important direction of efforts in high school chemistry education. In this paper, basic chemical concepts has been classified into three kinds according the learning concepts program.Based on constructivist theory, different kind of teaching process had been designed for help students build the full meaning of the basic chemical concepts, and to guide students to learn science research methods and scientific way of thinking and to improve the efficiency of teaching objectives. We also explore the design process of teaching and Established the basic process of teaching the basic concepts of various chemicals. Teaching practice shows that the process of teaching the basic concepts of chemistry paper designed for students hss high teaching efficiency. Now we divide the basic teaching process of this study into three types of as follows:Two basic programs of teaching physical concepts:first, let the students observe experiments, observe experiments demonstrated changes, analyze the changing principle, get the chemical reaction equation, and finally get the full information of the entity concept; The second is firstly to explore the theory, reasoning out possible chemical principles and chemical experiments to verify and sum up the definition of the entity concept.The basic process of teaching definition concepts:Teachers first need to understand the reasons for the establishment of a definition of the concept. And then raise questions about the design of the classroom, guiding students to find a solution; After that, they should tell them how to use the knowledge. Finally, students will be able to take the initiative to define the concept.There are two basic abstractions teaching process:The first thing is to observe, analyze results of common property, and then define the final application verification; Second is a thing (called prototypes) be learned from a property, find essential nature of things, the formation of the concept, using the concept of understanding the same thing.Results of this study not only enrich the basic concepts of principle in teaching high school chemistry, but also provide the teaching process optimization. And they also have practical significance in improving the quality of teaching high school chemistry. What’s more, it also provides examples for the training of chemistry majors. And it can be a good reference for the basic concepts of chemistry-teaching teachers.
