爱因斯坦说过,“兴趣是最好的老师”。如果学生对化学学习提不起兴趣,学习就会缺乏主动性、积极性,那势必会造成知识接受困难、易忘、上课不专心,学习分心。所以在化学教学中激发并培养学生的学习兴趣,是中学化学教学的任务之一,也是减轻学生课业负担提高课堂教学质量的有效途径。那么怎样才能有效地激发学生自主学习的兴 Einstein said, “Interest is the best teacher.” If students are not interested in chemistry learning, learning will lack the initiative and enthusiasm, it will inevitably lead to difficulties in knowledge, easy to forget, not concentrate in class, study distractions. Therefore, to stimulate and cultivate students ’interest in chemistry teaching is one of the tasks of chemistry teaching in middle school and also an effective way to reduce the burden of students’ study and improve the quality of classroom teaching. So how can we effectively stimulate the students’ autonomous learning?
