“最近发展区”理论在教学中的应用分析——以“DNA是主要遗传物质”为例
Analysis of the Application of the Theory of “Zone of Nearest Development” in Teaching—Taking “DNA Is the Main Genetic Material” as an Example

建构主义注重在已有经验的基础上构建知识，“最近发展区”理论关注学生的已有知识经验，预期潜在发展水平，进而提供学习支架。将“最近发展区”理论应用于“DNA是主要遗传物质”的教学设计和教学过程中，可有效地提升课堂的教学效率。
Constructivism emphasizes the construction of knowledge on the basis of existing experience, and the theory of “zone of nearest development” focuses on students’ existing knowledge and experience, anticipates the potential level of development, and then provides learning scaffolds. Applying the theory of “zone of nearest development” to the teaching design and teaching process of “DNA is the main genetic material” can effectively improve the teaching efficiency of the classroom.
