高中生物实验常常由于材料用具复杂、所需时间长、误差较大等原因,在学校里这些实验实施起来比较困难,所以我选择进行微课堂尝试。一、微课堂教学设计(一)自主学习。首先,在集体备课的基础上,针对所教班级学生学习情况制作导学案,辅之以预习案检测学生自学质量的跟踪练习,以及针对不同层次学生有选择的进行课堂巩固新知识的综合练习。其次,录制“探究酵母菌细胞呼吸的方式”探究实验过程的微课,课程时长10分钟,讲解实验 High school biology experiments often due to the complexity of materials and appliances, the time required, the error is large and other reasons, these experiments in school to implement more difficult, so I chose to micro-classroom try. First, micro-classroom teaching design (a) self-study. First of all, on the basis of collective lesson planning, we prepare a guide case for the learning situation of the students in the taught classes, supplemented by the follow-up practice of pre-test detection of students ’self-learning quality and the comprehensive practice of consolidating new knowledge in the classroom for different levels of students’ choices . Second, record “to explore the way yeast cells breathe ” to explore the micro-course of the experimental process, the course duration of 10 minutes to explain the experiment
