通过对《重力》一课的课堂观察和分析,得到启示:教师需要的不仅仅是理念的更新,更需要技术与能力的跟进;教师要有“用教材教”的理念,更要有解读教材的能力;要有“进行探究式教学”的理念,更要有处理猜想、引导学生探究的技术;要有“以人为本”的思想,也要有宽厚的学科知识. Through the classroom observation and analysis of “Gravity” lesson, we get the enlightenment that teachers need not only the renewal of ideas but also the follow-up of technology and ability; the teachers should have the concept of “teaching by teaching materials” more Have the ability to interpret teaching materials; to have “to explore teaching” concept, but also have to deal with conjectures, to guide students to explore the technology; to have “people-oriented ” thinking, but also generous subject knowledge.
