有效教学预设,可以简单地归结为两个方面。一是教学设计有效,二是课堂突破有效.教学设计,应以学生原有认知结构、知识发生发展的过程及逻辑规律为基础.这样,新知识会有好的生长点,学习内容也会形成一个整体,教学就会有灵魂,这给出了教学设计的一个宏观原则.但教学设计的具体流程该如何安排,才能更好地符合学生的认知结构及知识逻辑规律?针对教学设计中的重、难点内容,课堂教学中又要采取何种方式给以突破?笔者以为,马扎诺和迪安的“九项循证策略”是解决问题的有效方式之一.
Effective teaching presupposition, can be simply attributed to two aspects. First, effective teaching design, and second, effective breakthrough in the classroom teaching design should be based on the original cognitive structure of students, the process of development and logic of knowledge based on the law so that new knowledge will have a good point of growth, learning will Form a whole, teaching will have a soul, which gives a macro-principle of teaching design.But how to arrange the specific process of instructional design in order to better meet the student’s cognitive structure and logic of knowledge? For teaching design Heavy and difficult content, what method should be adopted in classroom teaching to make a breakthrough? The author believes that “one of the nine evidence-based strategies” of Marzano and Dean is one of the effective ways to solve the problem.
