为了让学生成为学习的主体,促进学生亲历学习过程,很多教师在化学课堂教学中都引入了教学案。教师通过教学案的帮助,可以让学生明确课堂学习目标和重难点,促进学生在课堂上有的放矢。在教学案的引导下,学生可以进行预习探究,了解学习方向,有利于课堂学习效率的提高。在课堂上教学案的出现让学生实现了更有效的自主、合作、运用探究,使学生在参与中进行逻辑思维和推理判断,从而提高学生的综合能力和对于知识的掌握。
In order to make students become the main body of study, and promote students to experience the learning process, many teachers have introduced teaching cases in chemistry class teaching. Through the help of teaching cases, teachers can help students clarify classroom learning goals and difficulties and promote students’ targeted education in the classroom. Under the guidance of the teaching case, students can make preview study and learn about the learning direction, which is conducive to the improvement of classroom learning efficiency. The emergence of teaching cases in the classroom enables students to achieve more effective autonomy, cooperation, the use of inquiry, so that students participate in logical thinking and reasoning to judge, so as to enhance students’ comprehensive ability and knowledge of mastery.
