基于核心素养的物理教具自制——以三原色为例
Self-Made Physics Teaching Aids Based on Core Literacy—Taking Three Primary Colors as an Example

为了将抽象的物理概念具体化，物理过程简单化，无形知识有形化，本文设计了光的三原色自制教具，该教具采用了生活中易于获得的实验器材，教具制作过程简单，实验现象明显。该创新型教具实验不仅符合初中生的脑生理特点、情感特点、思维特点，更能激发初中生学习物理的兴趣，进一步激发学生对物理创新型教具制作的热情，这对培养学生的逻辑思维、逆向思维、理性思维、创新思维、发散思维、抽象思维等能力具有重要的作用。
In order to concretize the abstract local concept, simplify the physical process and materialize the intangible knowledge, this paper designs a self-made teaching aid of three primary colors of light. The teaching aid adopts the experimental equipment which is easy to be obtained in life. The making process of the teaching aid is simple and the experimental phenomenon is obvious. The innovative teaching aid experiment not only conforms to the characteristics of junior high school students’ brain physiology, emotion and thinking, but also can stimulate junior high school students’ interest in learning physics and further stimulate students’ enthusiasm for making innovative teaching aids. It plays an important role in cultivating students’ abilities of logical thinking, reverse thinking, rational thinking, innovative thinking, divergent thinking and abstract thinking.
