根据高一学生化学知识少,实际技能差的特点,我们在高一两个班组织化学课外兴趣小组。兴趣小组活动内容,可先安排学生进行化学实验基本操作训练;再要求学生在阅读教材和有关课外读物后,自己写出内容提要,提出验证性或探索性实验课题。然后仍由学生自已拟订实验计划、组装仪器、动手实验。在整个过程中,教师只作必要的适当的指点,其余均由学生独立完成。有一次,学生在阅读课文后提出了一般书刊上未见过的课题“浓硫酸 According to the characteristics of high school students who have little knowledge of chemistry and poor practical skills, we are organized in a class of chemistry extracurricular interest groups in the top two classes. Interest group activities can be arranged for students to conduct basic training in chemical experiments; students are required to write their own abstracts after the reading of teaching materials and related extracurricular readings, and to propose confirmatory or exploratory experimental topics. Afterwards, the students still prepare their own experimental plans, assembly instruments, and hands-on experiments. During the entire process, the teacher only made necessary and appropriate guidance, and the rest was completed by the students independently. Once, after reading the text, the students put forward a topic that was not seen in the general literature.
