兴趣是知识的入门.瑞士著名教育家皮亚杰说:“所有智力方面的工作都要依赖于兴趣.”学生对学习有无兴趣,既是反映学生学习效率的重要标志,也是衡量教师教学成败的重要因素.因此,如何增强课堂教学的趣味性,激发学生学习的兴趣,使学生的学习变被动为主动,从而提高教学质量,就成为众多教师不懈追求、不断探索的课题之一:初三学生正处于兴趣广泛、求知欲旺盛的时期.教师如果从化学课的起始年级就注意激发和培养学生对化学学习的兴趣,则对保持学生化学学习经久不衰的求知欲是大有裨益的. Interest is an introduction to knowledge. The famous Swiss educator Piaget said: “All intellectual work depends on interest. ” Students have no interest in learning, it is an important symbol to reflect the efficiency of student learning, but also to measure teacher teaching An important factor for success or failure. Therefore, how to enhance the interest of classroom teaching, stimulate students’ interest in learning, make students’ learning become passive and active, and thus improve the quality of teaching has become one of the topics that many teachers have unremittingly pursued and continuously explored. The three students are in a period of wide interest and thirst for knowledge. If teachers pay attention to stimulating and cultivating students’ interest in chemistry learning from the beginning of the chemistry class, it is of great benefit to keep the students’ long-lasting curiosity in chemistry learning. of.
