"In terms of content, structure and language, science picture books are very different from story, prose and poetry picture books. The content of science picture books contains the real information of nature and society, and its structure is clear. Generally, knowledge and methods are listed and compared, while language is mainly plain descriptive words, with more new words and special vocabulary. " Based on the particularity of scientific picture books, how to grasp the "core experience" of teaching materials in collective teaching activities to "design diversified in-depth activities" is the focus of our exploration. In many attempts and practices, we realize that teachers should read textbooks intensively and use the two methods of "addition and subtraction" accurately before designing such collective reading activities.
Hope to adopt.
