自然常识教学的实验和观察对提高学生的理解能力和培养动手能力有很好的作用,但由于小学生知识的局限性,教学时数和实验条件的限制,有些实验或观察很难完成。为了提高效果,我试用电教与实验相结合的方法进行了一些尝试。一、运用电教手段解决实验、现察无法解决的问题例如第十二册《种向日葵》一课在用实验法进行教学时,由于时间条件限制,一节课内无法完成实验的全过程,更难看到向日葵生长过程的全貌,再加边动手边讲,小学生难以集
The teaching and observation of natural common sense teaching has a good effect on improving students’ understanding ability and training ability. However, due to limitations of primary school students’ knowledge, teaching hours and experimental conditions, some experiments or observations are difficult to complete. In order to improve the results, I tried some attempts using the combination of audio-visual and experimentation. First, the use of audio-visual means to solve the problem that cannot be solved in the experiment, such as the twelfth book “Sunflower Sunflower” lesson, when using the experimental method of teaching, due to time constraints, the whole process of the experiment could not be completed within one class, Difficult to see the whole picture of the growth process of sunflowers.
