学生虽然难以理解物质科学领域的许多抽象概念,但是容易接受直观化出现的现象、图形化表达的知识。通过“图画微粒”将隐性思维显性化,“材料自画”使显性实验表象化,“箭头示力”让受力分析清晰化,学生在图画表征的过程中,释放了想法,获得了方法,贯通了思维,习得了知识,并能逐步建构起物质科学领域的核心概念。 Although students are difficult to understand many abstract concepts in the field of physical science, but easy to accept the visual appearance of the phenomenon, the graphical expression of knowledge. Through the “drawing particles ” to explicit the occult thinking, “material self-painting ” makes the explicit experiment visualization, “arrow show force ” to force analysis clear, the students in the process of drawing representation, Released the idea, acquired the method, penetrated the thinking, acquired the knowledge, and gradually built up the core concepts in the field of material science.
