高职数学教师信息技术认识信念实证研究

Empirical Studies on Vocational Mathematics Teachers' Epistemological Belief about Technological Knowledge

信息化教学的推进和变革是以教师对信息技术的认识为前提的。信息技术认识信念是对TPACK的认知,具体地,信息技术认识信念包括TK的信念(包括意识、态度、能力、方式、适应性),是对信息技术知识的认知; TCK信念(技术与学科知识整合)和TPK的信念(技术与教学法的整合),即对技术作为工具,还是成为教学的方法,还是融入教学文化的认知。实证研究表明:信息技术认识信念各维度得分偏低,技术与学科教学的整合能力有待提升,信息技术认识信念处于工具观阶段。教师的TPACK和认识信念互相影响,认识信念对TPACK的各个维度有引领作用,而TPACK对信息技术认识信念提升有促进作用。教师信息技术认识信念提升要从理论、实践和操作三个层面进行考量。

The advances and reforms about information-based teaching are based on teachers'belief in technology.The epistemic belief about information technology is the cognition of TPACK.It includes two dimensions.One is basic dimension TK,including consciousness,attitude,ability,mode and adaptability,which is the understanding of basic knowledge of information technology;The application dimension is TCK and TPK,which is the cognition of the application and significance about integration of technology and subject,technology and teaching,that is,as a tool,as a teaching method,or as a teaching culture.The empirical results show that information belief score is low in all dimensions,the integration ability of technology and subject teaching needs to be improved,and the cognition of information technology is still in the stage of tool view.The teacher's TPACK and the cognition of information technology interact with each other,the cognition of information technology has a positive leading role in the various dimensions of TPACK,and TPACK may promote the cognition about information technology.Finally,the paper briefly introduces developing teacher's TPACK ability from three aspects of theory,practice and operation,and raises the significance of teachers'understanding of information technology.
