生物学教学挂图是目前生物学教学的常规手段,在讲解生物的形态结构、生理活动等问题上均能起到一定的直观效果。然而,多年来生物课所使用的教学挂图停留在平面图的状态,缺乏立体层次感,难以突出结构上的难点及演示生理活动的过程。为此我在这几年初一植物学教学中,以植物学教学挂图作为突破,对普通平面挂图的改进做了一些摸索和尝试。 Biology teaching wall chart is a common method of biology teaching. It can play a certain intuitive effect in explaining the structure and biological activities of living things. However, the teaching charts used in biology classes for many years stayed in the state of the floor plan, lacking a sense of three-dimensional hierarchy, and it was difficult to highlight structural difficulties and the process of demonstrating physiological activities. For this reason, in the botany teaching in the first few years of this year, I took botanical instructional charts as a breakthrough and made some attempts and improvements on the improvement of ordinary plane charts.
