Abstract In order to meet the requirements of engineering education certification, a comprehensive experiment of microwave synthesis and performance of starch-based super absorbent polymer was designed. The experiment involved the microwave-assisted synthesis, characterization and performance measurement of the super absorbent polymer based on starch and acrylic acid. In this experiment, students were required to consult literatures, understand various processes of preparation of super absorbent polymer and design the experimental scheme, master characterization technologies of ATR-FTIR and XRD and the testing technology of the swelling performance, and analyze the experimental data. In addition, an examination that integrated the process examination and result examination was also designed. Based on the teaching links such as experimental design, operation and data analysis, this examination could comprehensively evaluate the students' experimental abilities. This teaching scheme of the experiment not only improved the teaching quality, but also stimulated the students' interests in experiments and highlighted the cultivation of students' creative thinking as well as practical ability.
