美国小学的阅读课,有一种作业是让学生写《研究报告》。比如,三年级写《青蛙》。老师要求学生在家养几只小蝌蚪,天天观察蝌蚪的生长情况,记下它的变化。学生亲眼看到蝌蚪长出小腿,最后脱掉尾巴,蹦出鱼缸,小青蛙爬走了。他们根据自己的《观察日记》,写出上述的过程。 There is a homework reading class for American elementary schools where students write “research reports.” For example, the third grade write “frog”. The teacher asked the students to raise several small tadpoles at home and observe the growth of the tadpoles every day. Write down the changes. Students saw tadpoles grow their calves, and finally take off their tails, jumped out of the aquarium, a small frog crawled away. According to their own “observation diary”, they wrote the above process.
