Construction and Validation of an Online Teaching Model for the Development of Computational Thinking: Take high school information technology course as an example

In the information age, online teaching will gradually become an inevitable trend in the era of modern education informatization. Online teaching has the advantages of easy operation and abundant resources, but it has higher requirements for the design of teaching mode and teaching content. Computational thinking, as the core idea of IT teaching, emphasizes the long-term development and deep development of IT learning, which has great practical significance for students to improve themselves and cultivate their ability development. So in the online teaching of high school IT courses, how to build an online teaching mode suitable for students' development and achieve the purpose of effectively cultivating students' computational thinking? This study combines specific teaching, guided by constructivist theory, nearest developmental zone theory, situational cognition and other theories, and uses literature research method, questionnaire survey method, quasi-experimental research method and other research methods to conduct a study on the construction and validation of online teaching model of high school information technology geared to the cultivation of computational thinking. The results of the study showed that the proposed teaching model was found to have a significant promotion effect on students' academic performance and computational thinking through the examination of students' academic performance and computational thinking.
