设计思考九年级学生,从心理上对化学科学有一定的学习兴趣,为了让兴趣成为提高化学科学素养的钥匙,本节课回避对“分子、原子、元素及化学变化”等词语的解释.在结合学生知能背景的情况下,采用演示实验、学生实验、阅读、讨论交流等多样的形式开展教学活动,解决好“什么是化学?、化学有什么作用?、人类认识化学的历程?、化学的发展方向?”等问题.在各项有目的意义的活动中,促成学生及早对化学形成高尚的兴趣倾向.
Design thinking Nine grade students, psychologically have a certain degree of interest in the study of chemical science, in order to make interest become the key to improving the quality of chemical science, this class to avoid “molecules, atoms, elements and chemical changes ” and other words to explain In the context of combining students’ knowledge and ability, we should carry out teaching activities in various forms such as demonstration experiments, student experiments, reading, discussion and exchange and solve problems. “What is chemistry? What is the role of chemistry? , The direction of the development of chemistry? ”And other issues in a variety of purposeful activities, to promote students to chemistry as early as the formation of a high tendency of interest.
