Abstract:

Big idea-based teaching is an instructional paradigm that embodies the cultivation of competencies. The core of competencies is to solve real-world problems creatively, which better aligns with the mechanisms of high-road transfer. Guided by the methodology of the design experiment, the study took the “optimization” unit in elementary mathematics as an example. Firstly, the theoretical prototype of big idea-based teaching was refined through lesson study. A comparison was made between big idea-based teaching and conventional teaching from various dimensions of unit teaching, extracting elements and characteristics, and clarifying the model of big idea-based teaching, which was then exemplified. Subsequently, the effectiveness of the big idea-based teaching model was tested through comparative experimental research. The results of multiple regression analysis indicated that big idea-based teaching enhanced students' competencies, which was reflected in the enhancement of their ability for high-road transfer. Further analysis of students with varying levels of mathematical proficiency revealed that this instructional model could markedly improve the competencies of higher-achieving students in the short term and potentially benefit lower-achieving students over time.
