复习不应仅仅对所学知识进行一次机械的复述,而应进一步培养学生的能力,开拓学生智力。因此,我在组织学生复习《自然》第四册时,采用了下面三种方法。 1.再次实验。如,在《自然》第四册中,实验课的比例几乎占二分之一。许多基础知识,如机械的作用、金属的共同性质、空气的成分和性质等,都要求学生自己通过实验、讨论后获得。期终复习时,为了帮助学生加深对知识的理解,我不是把讲课时得出的结论重新抄给学生,让学生死记硬背,而是让学生再次做实验来回忆所学知识。如,复习“空气的成分及其性质”这一单元,我指定一名学生利用讲台上准备 The review should not only be a mechanical retelling of what has been learned, but should further develop students’ abilities and develop students’ intelligence. Therefore, when I organized the students to review the fourth volume of Nature, I used the following three methods. 1. Experiment again. For example, in the fourth volume of Nature, the proportion of experimental courses accounts for almost one-half. Many basic knowledge, such as the role of machinery, the common nature of metals, the composition and nature of air, require students to obtain experiments and discussions. At the end of the review, in order to help students deepen their understanding of the knowledge, I did not copy the conclusions drawn during the lecture to the students and memorized it. Instead, I asked students to experiment again to recall what they had learned. For example, to review the “Elements of air and its properties”, I designated a student to use the rostrum to prepare
