在小学自然教学中,运用多媒体CAI帮助学生理解自然实验的目的就是增强实验的直观性及可控制性,培养学生的观察、思维能力及空间想象能力。为此,我对以CAI辅助自然教学的实验进行以下设计:一、用多媒体CAI模拟实验现象,控制实验过程这主要是针对一些较难或实验周期较长的实验。这类实验虽然在课本上被列为演示实验,但因各方面原因较难完成,且不易显
In primary school nature teaching, the purpose of using multimedia CAI to help students understand natural experiments is to enhance the intuitiveness and controllability of experiments and to develop students’ abilities of observation, thinking and spatial imagination. For this reason, I carry on the following design to the experiment that assists natural teaching with CAI: First, use the multimedia CAI to simulate the experimental phenomenon, control the experimental course This is mainly aimed at some more difficult or experimental period long experiment. Although such experiments in the textbook was listed as a demonstration experiment, but due to various reasons more difficult to complete, and not easy to show
