Anonymous users2024-02-02Chemistry teaching design mainly includes two parts:
The first is the basic knowledge of chemistry teaching design, which briefly introduces the relevant theories of teaching design and the process mode of chemistry teaching design, and clarifies the analysis and design of various basic elements in the process of chemistry teaching design from the two levels of theory and practice, including the analysis of chemistry teaching content, the analysis of teaching objects, the writing of chemistry teaching objectives, the design of chemistry teaching strategies, the design of chemistry teaching, and the design of chemistry teaching evaluation.
Second, according to the concept of the new chemistry curriculum, combined with chemistry teaching cases, this paper analyzes how to design and organize the teaching design according to the characteristics of different types of chemistry knowledge, and how to design, organize and implement the learning methods advocated by the new curriculum.
