Aiming at higher vocational students’ confusion about mathematics learning, we draw on the “integration of doing, learning and teaching” to change the closed state of mathematics teaching, serving the lifelong development of students. The theoretical basis is Dewey’s educational theory, Tao Xingzhi’s educational thought, Bandura’s activity theory, Marx’s theory on the comprehensive development of human, and system science. Dewey’s theory emphasizes active work, Tao Xingzhi’s educational thought emphasizes a high degree of integration of students’ practice, teachers’ guidance and their joint learning, Bandura’s theory emphasizes the relative effectiveness of teaching and learning, Marx’s theory of “whole person” emphasizes treating human as a whole, and his theory of systematic science emphasizes the synergistic collaboration between education reform and other aspects. Through the research, we have developed an open classroom, an effective teaching structure, an effective teaching methodology, an effective curriculum carrier for constructing mathematical literacy-mathematical culture and practice activities, enabling the integration of mathematical history with teaching and learning, and the emotional input for mathematical diary.
