This study, set in Finland, explores how the theoretical framework of student engagement integrated into small-scale AR-based projects can be used to strengthen the nexus between theory and practice in language teacher education. Five student teachers partook in the study. Data consist of tasks connected to student engagement included in their study programme: initial teacher profiles, written reflections from their teaching practice, a project plan and poster based on their small-scale AR project, and a final group discussion. Findings are reported through narrative analysis. The findings show that the AR projects provided valuable opportunities for applying the theoretical framework of student engagement in practice, while also furthering the student teachers' understanding of the concept. Additionally, the benefits of repeatedly including the framework in connection to various tasks throughout the 20-week semester proved to be an important scaffold. This consistency in combination with a coherence between the university and practice school settings provided additional scaffolding. Challenges in relation to student teachers’ ability to apply the theoretical framework seemed connected to their current level of development on their journey to becoming teachers.</div></div>","PeriodicalId":48185,"journal":{"name":"System","volume":"133 ","pages":"Article 103789"},"PeriodicalIF":5.6,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without clarifying the factor structures and dimensionality of GenAI literacy, EFL teachers face challenges in effectively leveraging GenAI in their teaching. To address this gap, our study aimed to develop and validate a GenAI literacy scale for the Chinese EFL context, involving 603 EFL teachers. Specifically, a tentative scale comprising 38 five-point Likert items was administered to participants. Through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), the final scale was refined, evincing 32 items categorized into five dimensions: “<em>GenAI Knowledge</em>”, “<em>GenAI Use</em>”, “<em>GenAI Evaluation</em>”, “<em>GenAI Design</em>”, and “<em>GenAI Ethics</em>”. Moreover, statistical analysis also verified the scale's convergent validity and reliability in measuring the construct of GenAI literacy. We anticipate that this EFL teachers' GenAI literacy scale will guide teachers and teacher educators in enhancing GenAI capabilities for professional growth. It can also inspire them to innovate teaching with AI tools, thereby offering them fresh insights into GenAI literacy and its sub-components in the rapidly evolving landscape of AI-integrated EFL education.</div></div>","PeriodicalId":48185,"journal":{"name":"System","volume":"133 ","pages":"Article 103791"},"PeriodicalIF":4.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on the Experiential Learning Theory, which delineates how learners adapt and build new knowledge and skills through concrete experience, reflective observation, abstract conceptualisation, and active experimentation, this study found that students engaged with AI tools in a dynamic, iterative, and critical process when completing three course assignments. Through such engagement, they reflected on the effectiveness of specific tools and strategies and conceptualised AI’s utility in providing different types of assistance, culminating into the development of both specific and integrated, abstract metacognitive knowledge about when, where, why, and how to use AI in their learning. Such complex, interconnected knowledge was found to have further influenced their AI use through purposefully planning, exploring, monitoring, evaluating, and adjusting their AI strategies. The study also disclosed a generally negative perceived impact of AI use on language development, indicating the potentially detrimental effect of instrumental motivation for AI use. These findings highlight the need to reconceptualise metacognitive awareness as a synergistic system and the importance of fostering such awareness among students. Pedagogical implications are also drawn for teachers to design instructional activities that encourage students to actively reflect on their interactions with AI and regulate their AI strategies.</div></div>","PeriodicalId":48185,"journal":{"name":"System","volume":"133 ","pages":"Article 103790"},"PeriodicalIF":5.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144723043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These findings demonstrate the potential of AI-driven scoring in Turkish, offering valuable insights for broader implementation in under-represented languages, such as the possible source of disagreements between human and AI scores.

Students' gender did not affect these relationships, but additional exploratory analyses revealed interesting links between learners' L2 proficiency levels and their interaction-specific cognitions and engagement.
