观察、实验是人类认识自然的基本途径。可是在部分农村学校,由于经济比较落后,自然课中观察、实验所需器材严重缺乏。几年来,我利用农村小学丰富的自然资源条件,自备观察实验材料;利用身边材料,自制教具学具;结合农村小学实际情况,因地制宜,就地取材,较好地完成了教学任务。 Observation, experiment is the basic way of human understanding of nature. However, in some rural schools, because of the relatively backward economy and the observation in the nature class, the equipment needed for the experiment is seriously lacking. Over the past few years, I have used the abundant natural resources in primary schools in rural areas to prepare experimental materials by myself. I made use of the materials around me and made self-made aids for teaching aids. With the actual conditions of rural primary schools, I finished the teaching task well according to local conditions.
