Abstract Based on the diagnosis of learning situation, a large unit review with the theme of “catalyst and reaction regulation” was designed; in combination with the curriculum standard and the requirements of the college entrance examination, the advanced schema of cognitive development of “catalyst” was outlined, and three micro topics were organized with this as the teaching goal: “exploring catalyst and reproducing reaction process”, “entering the micro world:chemical reaction mechanism”, and “chemical reaction selectivity and catalytic agent activity”. Each micro topic selected test question cases, designed an explicit thinking path of the problem chain, evaluated the results of learning changes, so as to guide the formation of correct methods, strategies and cognitive models, and complete the systematic, comprehensive and micro essential understanding of the relevant content of the “catalyst”.
