Critical thinking(CT)is an important objective in education worldwide and ones' CT performance mainly depends on their cognitive dimensions of CT and affective dimensions of critical thinking(ADCT).Regardless the importance of ADCT,this paper of literature review and instructional design finds that,the research and development of ADCT are rudimentary.This literature review tries to contribute to this issue by 1)Identifying three important natures of ADCT,namely sensitivity,motivation and habits of mind towards CT(altogether called Key ADCT);2)Proposing various stages of developing ADCT for instructional intervention.Taking advantages of complementary features of a three dimension virtual learning environment and an asynchronous online discussion platform as well as their theoretical possibilities of facilitating individuals' CT development,a proposed instructional intervention for developing students' Key ADCT is suggested to be implemented in these platforms.All these suggestions form the foundation of a pilot study to be conducted in the near future.
