This paper presents a blended learning framework designed to cultivate computational thinking skills within the context of the "Introduction to Computer Science and Programming" course. By combining online and offline instructional approaches, the proposed model establishes a cohesive educational paradigm that seamlessly integrates computational thinking principles throughout the curriculum. Additionally, an evaluative model is introduced to assess proficiency levels in computational thinking. Through a meticulous analysis of empirical teaching data, the study confirms that the blend of instructional modalities is both a feasible and effective strategy for enhancing computational thinking competencies.
