In this paper, CTCL (Culture, Technology, Content, Learner) paradigm is used as a theoretical framework to discuss how to promote high school students' computational thinking during the transformation of cognitive deviation. "Network troubleshooting" in information technology is chosen as the learning content. In the experimental group, according to the connotation and characteristics of computational thinking, learners' cognitive deviations are measured and analyzed, and their causes are classified. Then, personalized learning is designed and implemented in order to improve computational thinking ability according to learners' cognitive types of deviations. The results show that the computational thinking level of the experimental group is significantly higher than that of the control group, which proves that personalized experimental teaching with the help of technology can effectively promote the cognitive change of learners' deviations, and significantly improve their computational thinking as well.
