学生初学化学时,实验较多,因此,化学课程对学生有很强的吸引力,随着知识内容的不断增加,特别是分子、原子、元素等概念的出现,学生深感学习化学一难二杂三抽象。于是有一部分学生,特别是基础薄弱的学生,产生了放弃学习化学课程的念头,渐渐地对学习化学不再感兴趣。这时,就需要老师采取以下各种有效的措施和方法,激活化学课堂,把学生的心留在化学课堂上,使绝大多数学生能保持学习化 Students learn more chemistry, the experiment is more, therefore, chemistry courses are very attractive to students, with the increasing content of knowledge, especially the emergence of the concept of molecules, atoms, elements, students are deeply learning chemistry difficult Miscellaneous three abstraction. As a result, some students, especially those with weak fundamentals, have given up the idea of ​​abandoning their studies in chemistry and are gradually losing interest in learning chemistry. At this time, teachers need to take the following various effective measures and methods to activate the chemistry class, leaving the student’s heart in the chemistry class so that the vast majority of students can keep learning
