“你印象最深的是哪一节课?”笔者曾经这样问过学生。如果学生想不出是哪一节课,就说明教师的课太枯燥;如果能给出答案,说明学生对这节课很感兴趣。学生只有乐学,才能够自主发现、思考、探索,从而学会。因而,兴趣在整个教学环节中能够引发“静水投石”的辐射效果。作为教师,该如何抛砖引玉、寓教于趣?通过 “What is your most impressed lesson? ” I once asked the students. If the student can not figure out which lesson he or she is taking, the teacher’s lesson is too boring. If you can give an answer, the student is very interested in the lesson. Only students learn music, be able to discover, think, explore, to learn. Thus, interest in the entire teaching process can lead to “static water stone” radiation effect. As a teacher, how to start a discussion, entertain in the fun?
