Abstract Core literacy of students’ development are mentioned in the Chemistry Curriculum Standard for Compulsory Education (2022 Edition)”, advocating that students are guided to solve interdisciplinary problems in real situations and cope with the uncertain challenges in the future. The teaching of H2O2’s decomposition always lacks of appropriate real situation, maneuverable experiments, comprehensively demonstration of knowledge, and the development of students’ quantitative thinking. Accordingly, the treatment of tumor hypoxia is taken as the teaching situation, which is run through by problem orientation, generated by innovative experiment, serviced by intelligent tablet, promoted by driven task, so that students can experience the whole process of scientific research, and effectively complete the teaching of H2O2’s decomposition and catalyst’s function.
