信息技术课程中某些抽象概念或原理,由于都是对自然现象的概括或间接反应,距离学生生活经验较远,因此学习者在学习时难以理解,这对教师的教学提出较大挑战,因此需要尽可能贴近学习者经验才能促进其理解。类比教学法能够为教师提供一种有效的概念或原理教学策略,本文主要阐述何为类比教学法;然后梳理教材中适宜运用类比教学的抽象概念与原理;最后给出具体的类比教学案例。
Because some abstract concepts or principles in IT courses are all general or indirect reactions to natural phenomena and are far from students ’life experiences, learners find it hard to understand while studying. This poses a great challenge to teachers’ teaching. Therefore, It needs to be as close to the learner’s experience as possible to promote its understanding. Analogy teaching method can provide teachers with an effective concept or principle of teaching strategies, this paper describes what is analogy teaching method; then combing textbooks in the appropriate use of abstract concepts and principles of analog teaching; and finally give a specific case of analog teaching.
