在高中的学习中,学生要学习的科目多、内容多,但是学习时间都有限,而化学科在高一阶段一般每周只有三节课,高二选修了理科之后也只有四节课。如何才能使学生在有限的时间里最大限度地提高学习效率就显得极为重要,这就要求我们教师不但要不断地充实新知识,调整知识结构,还需要我们细心地去观察和接受来自学生的反馈信息,还要能够换位思考,从学生角度来考虑学生喜欢上怎样的化学课,教师才能随时调整自己的行为和预定的教学计划,才得以实现最优化的教学, In high school, students are required to learn more subjects and more contents, but their study time is limited. However, Chemistry has only three classes per week in high school and only four classes after sophomore electives. How to make students maximize the learning efficiency in a limited time is very important, which requires that we teachers not only continue to enrich new knowledge, adjust the structure of knowledge, but also we need to carefully observe and accept the feedback from students Information, but also be able to empathy, from the perspective of students to consider what kind of chemistry students like, teachers can always adjust their behavior and scheduled teaching plan, to be able to achieve optimal teaching,
