问题情境,是指个体觉察到的一种有目的但不知如何达到这一目的的心理困境,也就是当已有知识不能解决新问题时而出现的一种心理状态。要摆脱这种处境,必须拟出以前未曾有过的、新的活动策略,亦即完成问题情景的创设。如何在物理教学中创设问题情景呢?下面从几方面通过一些课堂教学片段谈谈对此的一般做法。一、巧用演示实验创设问题情境片段1:在进行“自由落体运动”的教学时,教师首先演示:让两个大小一样的纸片和金属片从
The problem context refers to a psychological predicament perceived by the individual who is purposeful but does not know how to achieve this purpose, that is, a state of mind that arises when the existing knowledge can not solve the new problem. To get out of this situation, we must draw up a new strategy for activities that we have never had before, that is, to complete the establishment of a problematic situation. How to create a problem scenario in physics teaching? Here are some aspects of the general approach to this through a number of classroom teaching fragments. First, the clever use of demonstration experiments to create the situation Fragment 1: In the “free-fall movement” teaching, teachers first demonstrate: Let the same size of the two pieces of paper and metal from
