提高每位学生的有效学习是摆在每个化学教育工作者面前的重要课题。提高学习效果一般有两种方法,一是向学生要时间,那样不仅会增加学生负担,而且也是不现实的。另一种方法是化学教师应该努力提高驾驭课堂教学的能力,通过学生多讲、多问和反思等途径来提高学习效果。 Improving each student's effective learning is an important issue for every chemistry educator. There are generally two ways to improve the learning effect. One is to take time from the students, which will not only increase the student's burden, but also unrealistic. Another way is that chemistry teachers should strive to improve their ability to control classroom teaching and improve their learning through such ways as how students can speak, ask and reflect.
