物理探究活动离不开观察与实验,观察与实验又离不开师生共同准备的实验探究材料。为了使学生的物理探究活动有效进行,教师必须给学生提供有结构的材料。一、物理教学注重实验操作如,在教学《声音的产生和传播》一课时,我先借助多媒体课件创设一个静谧的月夜情境,然后播放几种不同的声音。考考大家的听力:你听到了几种声音?你能学学它们发出的声音吗?面对熟悉的声音,学生很快就回答出来,并惟妙惟肖地模仿出听到的
Physical exploration activities can not be separated from observation and experiment, observation and experiment can not be separated from teachers and students to prepare experimental exploration materials. In order for the student’s physics inquiry activity to work effectively, the teacher must provide students with structured materials. First, the teaching of physics Focus on experimental operations, such as teaching “sound generation and dissemination of” a lesson, I use multimedia courseware to create a quiet moonlight situation, and then play several different sounds. Test everyone’s hearing: How many voices have you heard? Can you learn what they say? Faced with a familiar voice, students quickly answer it and mimic what it has heard
