学生的化学学习内容应当是现实的、有意义的、富有挑战性的,这些内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等化学活动。要以学生为中心设计教学,改变学生的学习方式,抓住重点,实现化学教学的三维目标,要贴近生活,延伸向其它学科,培养学生的综合素质。 Students ’chemistry learning content should be realistic, meaningful and challenging. These contents should be conducive to students’ initiative in conducting chemical activities such as observation, experiment, guesswork, verification, reasoning and communication. Students should be the center of the design of teaching, change the way students learn to grasp the key to achieve the three-dimensional chemical teaching goals, to be close to life, extending to other disciplines to develop the overall quality of students.
