论文部分内容阅读
科学建立在实验的基础上,然而一堂课的时间是有限的。一个内容里有多个知识点,每个知识点都准备一个实验,这样会使教师准备繁琐,课堂效率低下,并且整体性不强。本来多个知识点在一个内容中,彼此间有一定的联系,文章针对这个关系,对植物呼吸作用的三个原分散的实验,进行了整合。并科学地应用生活中的物品来替代实验室仪器,让学生能在课后自主地研究。
Science is based on experimentation, but the duration of one lesson is limited. There is more than one point of knowledge in a piece of content, and each point of knowledge prepares an experiment, which will make it tedious for the teacher, inefficient in class, and not very comprehensive. Originally a number of knowledge points in a content, there is a certain relationship between each other, the article for this relationship, the plant’s respiration three dispersed experiments. And the scientific application of life items to replace laboratory equipment, so that students can study independently after class.
