美国教师在教学中注重学生的动手操作能力,让学生在实践中进行教学。在美国有为数不少的由各学科专家编写而成的指导教案供一线教师参考,其中就罗列了较多根据不同年龄学生设计的课堂实验的教案。在此,本人选取美国中学生物课中关于“细胞”课堂实践的教案进行简单介绍,希望相关教师能有所裨益。 American teachers pay attention to students’ hands-on skills in teaching and allow students to teach in practice. In the United States, there are a large number of instructional lectures prepared by experts from various disciplines for reference by first-line teachers, among which are more lesson plans based on classroom experiments designed by students of different ages. Here, I will briefly introduce the lesson plans on the practice of “cells” in the American High School Biology class. I hope relevant teachers can benefit from it.
