中学化学教学大纲中对化学总复习提出了如下指示:“最后学年的总复习应该以学生在学习化学的最后阶段所掌握的定律和学说为基础,也就是以门捷列夫周期律和原子结构学说为基础,按元素周期表的体系,有计划地、概括地、有重点地去复习以前各年级所学过的教材。”我在高中化学总复习中,根据这个指示去复习各部分教材,事实证明不仅能使学生对学得的知识更系统化、而且更加巩固。根据个人的体会,以周期律和原子结构学说为基础去复习以前各年级所学过的教材,教师必须深入发掘和抓住教材的中心实质,在突出这一中心实质的基础上去复习具体的教材内容,或由具体教材内容的复习去突出中心的实质,这样才能达到总复习的目的。因为这样复习不仅学生能把一些似乎是零碎的化学知识提高到理论的认识,而且把这些知识严密地系统化。
The General Chemistry Syllabus for Secondary Chemistry presents the following instructions to the General Review of Chemistry: “The total review of the final year should be based on the laws and doctrines students have in the final stages of learning chemistry, that is, based on Mendeleev’s periodic law and atomic structure Doctrine as the basis, according to the periodic table system, in a planned, general and focused manner to review the materials learned in previous grades. ”I am in the general high school chemistry review, according to this instruction to review the various textbooks, Facts have proved not only to enable students to learn more systematic knowledge, and more consolidated. According to personal experience, based on the periodic law and the atomic structure theory to review the materials learned in previous years, teachers must dig deep into and grasp the essence of textbooks, review the specific textbooks on the basis of highlighting the essence of this center Content, or by the specific content of the textbook review to highlight the essence of the center, so as to achieve the purpose of the total review. Because of this review, not only can students elevate some seemingly fragmented chemical knowledge to theoretical knowledge, but also systematize it.
