在自然课教学中,有些观察项目需要长期 进行,如第一册第十三课《怎样测定太阳高 度》,观察一年中太阳高度的变化;第二册第一 课《我们来给大自然记日记》(分别在第二册第 十二课、第十八课,第三册第一课,寒假作业中 出现。第五册第十四课《四季是怎么形成的》 要用到观察记录)。类似情况还有很多。如何 指导学生进行长期地观察、记录呢?现以第四 册第一课第5作业题和第五册第一课第3作 业题(要求学生观察月亮在农历一个月中位置 和形状变化并进行记录)为例,谈谈我的一些 做法和体会。
In the teaching of nature, there are some observation projects that need to be carried out for a long time, such as Volume 13, “How to Determine the Height of the Sun,” and observe changes in the solar altitude over the year; Book 2, “The Book” Diary “(respectively in the second volume of the twelfth, eighteenth, third book first class, winter vacation homework fifth book fourteenth” four seasons is how to form "to use observation records) . There are many similar situations. How to guide students to observe and record for a long time? Now the fourth volume of the first lesson of the fifth assignment and the fifth of the first lesson of the third assignment (require students to observe the moon in the lunar month position and shape changes and Record) as an example, talk about some of my practices and experiences.
