Theoretical and Practical Dilemmas on Big Concept Teaching
Based on the need to develop key competences,big concept teaching uses"big concept"to open up the connection between school education and the real world,and to cultivate the literacy of solving au-thenticity problems,which is the hot spot of the current teaching transformation.However,big concept teach-ing is still facing the dilemma of both theoretical research and practice:theoretically,big concept teaching has more macro-theoretical research and less micro-concerns,more theoretical conception and lack of practical support,more commonality research and less individuality research;practically,big concept teaching is limited by the tripartite practice subjects of schools,teachers and students,and there are many dilemmas in the practi-cal operation of"big concept"extraction,textbook arrangement,design misunderstandings,and evaluation.Therefore,the implementation of big concept teaching needs further research and practical tests,and it is bet-ter to look at big concept teaching with a dialectical perspective.
