从知识的生长点、化学思想与方法、逻辑性和层次性、多样性、思维发展性、观察方法等六个视角,研究有效问题设计的价值取向,提出有效问题设计要保证预设与生成的统一,要关注化学思想和方法,要促进学生的思维发展。同时指出应用课堂观察技术,推动主题研修,有利于促进合作共享的教研文化形成。 This paper studies the value orientation of effective problem design from the point of view of knowledge growth, chemical thought and method, logicality and hierarchy, diversity, development of thinking and observation method, and puts forward that the design of effective problem should ensure the preconceived and generated To unify, we should pay attention to chemistry ideas and methods, and promote the development of students’ thinking. At the same time, it points out that the use of classroom observation techniques to promote thematic training is conducive to the formation of the teaching and research culture that promotes cooperation and sharing.
