小学数学“先学后教”是以学生的“先学”为前提,让学生带着教师精心设计的导学案进行有目标的预学。因此,编写实用、适用和有效的导学案是提高“先学”质量的关键。但是,目前导学案的设计还存在机械照搬教材内容、问题缺乏思维含量和内容设计混乱无序等现象。现结合具体案例进行问题剖析并提出相应改进策略。一、机械照搬教材内容——导学粗糙
Primary Mathematics “The first to teach” is based on the students “first learning ” as a prerequisite for students to conduct targeted learning with teachers carefully guided learning case. Therefore, the preparation of practical, applicable and effective guidance is to improve the quality of “learning” key. However, there are still some problems such as the content of mechanically copied teaching materials, the lack of thinking content and the disorderly and disorderly design of content in the design of the guide case. Now combine the specific case analysis of the problem and propose corresponding improvement strategy. First, mechanical copy teaching material content - rough guide
