Abstract The redox reaction tests were selected as the materials, eye tracking technology was used to conduct a 3 (academic level) *3 (test difficulty) two factor mixed experiment on 12 senior one students. After the experiment, a follow-up oral report was carried on. The results show that premium students' information processing speed is fast, the depth is shallow, and the difficulty is small, the combination strategy of forward processing and reverse elimination can be used, and can be well combined with the stems and options in the process of solving the problem of redox reaction. Medium students' information processing speed is slow, the depth is deep, and the difficulty is great, the forward processing strategy can be adapted; and the attention is paid more to the problem stem. Students with learning difficulties' information processing is ineffective, easy to give up, and the attention is paid more to the problem options. With the increase of problem difficulty, the information processing speed becomes slower, the depth becomes deeper and the difficulty becomes larger.
