    To address the challenges of outdated teaching resources, insufficient practical skills, and a lack of value-oriented guidance in education, this study constructs an innovative pedagogical model driven by the dual-engine of large language model (LLM) and open source ecosystem. The model is designed to bridge the gap between theoretical knowledge and real-world engineering practice by integrating open-source tools, dynamic code repositories, and authentic project scenarios into the curriculum. Meanwhile, LLMs are employed as intelligent teaching assistants to enable personalized learning paths, generate automated feedback, and support immersive ideological and ethical modules. This research was implemented in the course “Artificial intelligence and its applications”, where a mixed-method evaluation was conducted. Quantitative metrics such as attendance, interaction frequency, repository contributions, and assignment performance were used to measure student engagement and learning effectiveness. Additionally, a set of custom-designed assessment formulas was used to evaluate cross-platform transferability and community participation. Experimental results from 90 undergraduate students showed that learners engaged in open-source collaboration and LLM-assisted learning achieved significantly higher scores in both technical proficiency and value cognition than those in the control group. The study demonstrates that the integration of LLMs and open-source collaboration can effectively enhance student autonomy, promote engineering skills, and reinforce ethical awareness. This dual-driven model not only offers a feasible approach for modernizing AI education but also contributes to the broader goal of cultivating socially responsible and technically competent AI talents.

    J* E* C* N* U* N* S*    2025, 2025 (5): 76-86.   DOI: 10.3969/j.issn.1000-5641.2025.05.008

    Cognitive diagnosis, a core task in personalized education, aims to evaluate students’ mastery of knowledge points using historical response records. Existing static cognitive diagnosis models are typically based on manually annotated key knowledge points, ignoring potential correlations between knowledge points within items as well as differences in how items emphasize specific knowledge points. To address these limitations, this study proposes a static cognitive diagnosis model improved by knowledge point relations (Q-matrix Enhanced Neural Cognitive Diagnosis, QENCD) model. The model optimizes the item-knowledge point association vector by constructing knowledge point dependency relationships and item emphasis information, then integrating these features through residual connections. The experimental results showed that QENCD model significantly outperforms existing models on the ASSIST09, ASSIST17, and Junyi datasets significantly outperforming state-of-the-art baselines. This study provides a more precise knowledge modeling method for static cognitive diagnosis.

    Student employment prediction for digital jobs based on behavior in open-source communities
    Linna XIE, Xuesong LU
    J* E* C* N* U* N* S*    2025, 2025 (5): 87-98.   DOI: 10.3969/j.issn.1000-5641.2025.05.009

    Accurately predicting students’ post-graduation career paths plays a vital role in talent development in higher education and in refining recruitment strategies in industry. Most existing employment prediction research relies heavily on academic or campus-related data, while overlooking the role of students’ open-source contributions in the process of securing digital-related positions. This study addresses employment prediction for digital roles by analyzing students’ behaviors in open-source communities. We construct a heterogeneous graph comprising student nodes, code repository nodes, and various semantic relationships to model students’ expertise. To enhance prediction performance, we propose two strategies that integrate large language model (LLM) with graph neural networks: LLM-as-Encoder and LLM-as-Explainer. Experiments on our curated dataset show that the proposed approach outperforms baseline methods, achieving improvements of 7.71% in accuracy and 9.19% in Macro-F1. By leveraging open-source activity, this study supports data-driven decision-making for university career services, aids enterprises in identifying technical talent, and provides students with actionable insights for career planning.
