美国生物学“5E”教学模式的内涵、实例及其本质特征

The Teaching Content,Examples and Essential Characteristics of "5E" Model

＂5E＂教学模式是美国生物学课程研究开发的一种基于建构主义教学理论的模式,它的五个环节是吸引、探究、解释、迁移和评价。＂5E＂教学模式十分注重教师的教学行为与学生的学习行为协调一致。学生是学习的主体,是活动的中心,教师是指导者和帮助者的角色,教师所做的一切,都是为了促进学生更好地探究而获取科学的概念。强调学生的自主构建是＂5E＂教学模式的核心,形成新旧概念之间的冲突是主动建构概念的动力,建构概念并应用概念是＂5E＂教学模式的重要内容。

The five links of the 5E teaching model refer to engagement, exploration, explanation, elaboration and evaluation, which attache great importance to the coordination of the teaching behavior and learning behavior. Students are the subject of the learning activities, whereas teachers are mentors and helpers. Everything that the teacher does is to facilitate the students to inquire and acquire the scientific concepts. To emphasize the students＂ self-construction is the core of 5E teaching model, and to form the conflict between the old and the new concepts is the power of the self- construction. Construction and application of concepts are the essential part of 5E teaching model.
