在大学读书时,老师给我们上的种各理论课,几乎每节课都用一定数量的幻灯片来辅佐教学。我们深有体会,往往一些深奥抽象的问题,一旦变成图象以幻灯影片映出时,会使人豁然开朗,印象特深。因为生物科学是一门实验性科学,一旦艰涩的文字与活生生的实物结合在一起,再难的问题也变得容易了。大学毕业后,在中学任教。在教学过程中,教师们用得最多的是挂图。挂图在生物教学过程中有其独特的作用,但挂图毕竟太死。 When I was studying at a university, the teacher gave us all kinds of theoretical lessons. Nearly every class used a certain number of slides to help teach. We have profound experience, often with some esoteric and abstract problems. Once we turn into images and show them in a slide show, we will make people suddenly feel very impressive. Because biological science is an experimental science, once difficult texts are combined with living physical things, difficult problems become easier. After graduating from university, he teaches in middle school. In the teaching process, most teachers use wall charts. The flipchart has its own unique role in the biological teaching process, but the wall chart is too dead after all.
