Dual Effects of Artificial Intelligence on Critical Thinking and Creative Self-Efficacy of Engineering Undergraduates: The Mediating Role of Cognitive Engagement

With the deep penetration of generative artificial intelligence (GenAI) in higher engineering education, its impacts on students’ higher-order thinking skills and underlying mechanisms remain controversial. Grounded in the ICAP cognitive engagement framework, this study integrates cognitive unloading theory, dual-process theory, and cognitive load theory to construct a moderated mediation model of “usage pattern—cognitive engagement—ability outcome”. It examines how different AI usage patterns differentially affect engineering undergraduates’ critical thinking and creative self-efficacy, as well as the boundary moderating role of task complexity. Adopting a two-wave longitudinal questionnaire design, this study surveyed 428 engineering undergraduates from a Double First-Class university in western China, and conducted empirical tests via structural equation modeling and the Bootstrap method. Results show that the theoretical model fits the data well. Instrumental use positively predicts shallow cognitive engagement, which in turn negatively affects critical thinking, presenting an “erosion effect”. Exploratory use positively predicts deep cognitive engagement, which significantly enhances creative self-efficacy, presenting an “enablement effect”. Task complexity plays a positive moderating role in the first half of both mediation paths: higher task complexity amplifies both the cognitive erosion risk of instrumental use and the cognitive enablement effect of exploratory use. This study confirms the dual effects of AI in engineering education and reveals that depth of cognitive engagement is the core regulatory mechanism of technology application effectiveness, providing theoretical and practical references for reconstructing engineering talent cultivation models in the AI era.
