2012年9月,浦东新区首批理科教师境外培训团队来到美国马里兰州陶森大学参加为期四周的培训。在此期间,我们共参观了8所中学,听了20多节课,不仅充分体会了两国理科教学方式的差异,更体验到了美国化学实验教学的魅力。下面以玛丽维尔预备学校的《物质的分离》这堂初中化学实验课为例,来谈谈从中获得的启示。根据教学要求,这节课学生需要学会把固体、液体或者气体混合物进行分离。教师对这节课的要求 In September 2012, the first overseas training team of science teachers in Pudong New Area came to Towson University in Maryland to attend a four-week training program. During this period, we visited a total of eight high schools and listened to more than 20 lessons. They not only fully realized the differences in science teaching methods between the two countries, but also experienced the charm of the American chemistry experiment teaching. Let’s take a look at the lessons learned from the junior high school chemistry experiment lesson entitled “Material Separation” at Maryville Preparatory School. According to teaching requirements, students in this class need to learn to separate solid, liquid or gas mixtures. Teacher’s requirements for this lesson
