物理教学是一门很深的艺术,有的老师课堂妙趣横生,跌宕起伏,学生积极参与,而有的则一潭死水,枯燥乏味,学生昏昏欲睡,其实一节课从问题情境到回顾反思各个环节都是大有文章可作,若要求一节课的每个环节都精妙绝伦,那也是不切实际的,不过只要经过精心思考,每节课中总可以有一些精彩的“短镜头”.在“电容”这节课的教学设计和实践中,我们看到了新课程三维目标得到有机融合,问题情景的有效创设,实验设计的精巧,逻辑顺序的流畅和认识上的螺旋式上升.这节物理课的设计依据教材但不拘泥于教材,教学形式、方法和手段有别于常规的课. Physics teaching is a very deep art. Some teachers are entertaining, ups and downs in class, active participation of students, while others are stagnant, dull and sleepy. In fact, a lesson from the problem situation to review all aspects of the review It is impractical to require that every aspect of a lesson be exquisite, but only after careful consideration, there may always be some wonderful “short shots” in each lesson, In the teaching design and practice of “Capacitance ”, we have seen the organic integration of the three-dimensional goals of the new curriculum, the effective creation of problem scenarios, the exquisite experimental design, the smooth flow of logic and the spiral of understanding This physical lesson is designed on the basis of textbooks but is not limited to textbooks, forms of teaching, methods and means as distinct from regular lessons.
