Interdisciplinary thematic teaching is an innovation in teaching methods under the background of the new curriculum reform, but it is still in the stage of teaching practice exploration. To correctly apply interdisciplinary teaching and avoid the situation of putting the cart before the horse, in the teaching practice of “sports+”, we should adhere to the “essence” as the center and expand the breadth of subject knowledge; Deepen the “cross” function and accelerate the cross fusion of knowledge; Consolidate the foundation of “learning” and strengthen the comprehensive educational effect. By enhancing overall understanding, streamlining the integration framework, emphasizing scenario based teaching, enriching social experiences, improving positive feedback evaluation, and achieving a cycle of good teaching and evaluation, we can better leverage the value and significance of interdisciplinary teaching and achieve the educational goal of comprehensive education.
