新课程实施以来,“案例教学法”日益被广大教师所关注。但什么是案例教学?案例教学和举例说明有何不同?案例和情境有何区别?怎样选取适当的教学案例?怎样运用案例进行有效的教学……虽然新课程已实施多年,但很多教师对于“案例教学”的理解和使用仍较为混乱。鉴于此,笔者提出了“中学地理新课标下资源性案例教学研究”的课题,并进行了深入研究。历经三年多的课题研究,笔者及团队运用文献研究和行动研究法,最终获得了一些初步的成果,包括理论的创建和初步成型的中学地理教学案例资源库。其中特别突出的成果是创建性地提出了“变式案例”的概念,并提出了相应的教学策略,本文对此展开介绍。 Since the implementation of the new curriculum, “case teaching method ” has been increasingly concerned by the majority of teachers. But what is case teaching? What is the difference between case teaching and illustration? What is the difference between case and situation? How to choose the appropriate teaching case? How to use case to carry out effective teaching ... Although the new course has been implemented for many years, The understanding and use of Case Teaching is still a bit confusing. In view of this, the author puts forward the topic of “resource case teaching under the new curriculum standard of middle school geography” and conducts in-depth research. After more than three years of research, the author and his team finally achieved some preliminary results by using the methods of literature research and action research, including the creation of the theory and the initial formation of the middle school geography teaching case resource base. One of the most outstanding achievements is the creative creation of the concept of “variant case”, and puts forward the corresponding teaching strategy, which is introduced in this article.
