The"Entrance Barriers"of Large Unit Teaching and Its Solution
The"entrance barrier"of large-unit teaching refers to a state of being in trouble in which large-unit teaching fails to become a teaching practice because of various reasons,that shows as the"unit"cognitive barriers of teachers teaching,"concept"design barriers and"subject-based"barriers in the implementation.The reasons are as follows:the cognitive limitation of"small unit"caused by nested logic,the conceptual design inertia to difficulties of extracting the goal of core lit-eracy,as well as the consolidation of the disciplinary patterns caused by the formalized inquiry and stereotyped teaching.In order to break through the"entrance barriers"of large-unit teaching,it is necessary to grasp the meaning of"Big"in large-unit teaching,to break through the cognitive limitation of small-unit teaching,and to use"Big concept"to guide teaching designs,we should break through the design limitation of the point distribution of the teaching knowledge of"Small con-cept",and break through the disciplinary limitation of rigid implementation with teaching at the core literacy level.
