预习作业就是引导学生去预习将要讲解的知识,不同类型的预习作业会有不同的课堂效果。在我的教学中,我较为注重记录型预习作业、操作型预习作业和验证型预习作业。记录型预习作业有助于学生整体的感知课堂内容,形成框架结构。操作型预习作业有助于学生亲自体会知识的演绎过程,提升操作能力。验证型作业则有利于学生们感受知识的严谨性,鼓励猜想。这样,教师充分的优化设计预习作业,就会大大提升课堂效率。
Pre-homework is to guide students to preview the knowledge to be explained, different types of pre-homework will have different classroom effects. In my teaching, I pay more attention to the recording preview operation, the operation preview operation and the verification preview operation. Record-based preview exercises help students to perceive classroom content as a whole and form a framework. Operational preview exercises help students to understand the process of deduction of knowledge and improve their ability to operate. Validated jobs help students feel the rigor of knowledge and encourage conjecture. In this way, teachers fully optimize the design of pre-homework, it will greatly enhance classroom efficiency.
