Abstract During the teaching implementation of the chemical learning task of “exploring the influence of concentration on chemical reaction rate”, students are guided to find a breakthrough to solve problems, design and implement exploratory experiments, and form cognition. Teachers present data cards, triggering students’ cognitive conflict and questioning; teachers and students work together to find a breakthrough to solve the problem and further develop students’ understanding of the impact of concentration on chemical reaction rate. In the teaching practice, we should stimulate students’ questioning spirit, mold students’ necessary character and improve students’ key ability.
