近年来,我们将投影仪应用于初中化学教学中,初步收到了良好的教学效果。它既有利于培养学生的能力,又有利于教改的顺利进行,充分显示了投影仪在教学中的积极作用。现就投影仪在实验教学、课堂教学及能力培养中的应用简述如下: 一、投影仪在教学中的具体应用: 1.以“投影仪教学”代替“黑板教学” 投影仪教学能激发学生的学习兴趣,增加课堂教学密度,提高课堂教学的效率。 心理学认为:“刺激物的强度是引起学生无意注意的重要原因。”“新东西更容易成为注意的对象”。
In recent years, we have applied projectors to junior high school chemistry teaching and have initially received good teaching results. It is not only conducive to the cultivation of students’ ability, but also conducive to the smooth progress of teaching reform, and fully shows the positive role of the projector in teaching. The application of the projector in experimental teaching, classroom teaching and ability cultivation is briefly described as follows: 1. The specific application of the projector in teaching: 1. Replace “blackboard teaching” with “projector teaching” Projector teaching can stimulate students The interest in learning increases the classroom teaching density and improves the efficiency of classroom teaching. Psychology believes that: “The intensity of stimuli is an important cause of students’ unconsciousness.” “New things are more likely to be the object of attention.”
