“问题驱动”是一种教学策略,是指在有限的化学课堂时间内,设计一系列化学问题来驱动课堂教学,问题要环环相扣、让学生在好奇心驱使下逐步逼近所教主题的化学本质,体验化学探索中乐趣.那么,如何更有效开展“问题驱动”的这一教学策略?一、教师能对各模块中相关内容要有清晰比较与分类奥苏贝尔在《教育心理学-认知观点》的扉页上写道:“假如把全部教育心理学归结为一条原理的话,那么我将一言以蔽之:影响学习的惟一重要因素就是学习者已经知道了什么.要探明这一点,并应据此进行教学.”因此,教师要首先从学生已有的知识和生活中的一些常识开始,才有可能设计出一系列有 “Problem-driven ” is a teaching strategy, which refers to the design of a series of chemical problems in a limited number of chemical classrooms to drive classroom teaching. The problem should be closely linked so that students can gradually approach the teaching under the curiosity Theme of chemical nature, to explore the fun of chemical exploration.Then, how to more effectively carry out “problem-driven ” This teaching strategy? First, the teacher can have a clear comparison and classification of the relevant content of each module Ausubel “ On the front page of Educational Psychology - Cognitive Perspectives, I wrote: ”If we put all educational psychology down to one principle, then I can state: the only important factor affecting learning is what learners already know To prove this, teaching should be done accordingly. "Therefore, teachers should first of all start from the students’ existing knowledge and common sense in life to make it possible to design a series of
