Drawing on data from 2148 teachers across eleven autonomous communities, a structural equation model (CB-SEM) was developed and validated to examine the interplay between knowledge, value-based evaluations, expectations, and perceived usefulness and acceptability of DER. Findings reveal that, while teachers generally report positive attitudes towards DER, adoption is not uniform; four distinct evaluative profiles were identified, ranging from scepticism to full integration. Expectations about the future development and ubiquity of DER emerged as the strongest predictor of adoption, outweighing technical knowledge. The results suggest that, in post-pandemic educational contexts where structural barriers are largely overcome, intrinsic and dispositional factors are more decisive than access or infrastructure. The study highlights the influence of digital determinism and anticipatory beliefs, which can lead to uncritical integration. It calls for differentiated, critical professional development programmes that support reflective and pedagogically grounded use of digital resources. Limitations include sampling constraints, instrument validity, and the need to contextualise DER more precisely. These findings contribute to the broader debate on technology integration in ECE and offer a foundation for future research and policy development.</div></div>","PeriodicalId":10568,"journal":{"name":"Computers & Education","volume":"238 ","pages":"Article 105396"},"PeriodicalIF":8.9,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During KB activities, various emotions may arise due to students' diverse ideas, theory-building, as well as cognitive equilibrium and disequilibrium. Depending on the different development levels of the inquiry threads, the emotions may differ. An inquiry thread is a series of notes that address the same problem or topic. Despite increasing recognition of the importance of emotions in KB, or more generally, in computer-supported collaborative learning (CSCL), there is a lack of empirical studies systematically examining the dynamics of these emotions, particularly how they vary across different types of collaborative inquiry threads. Addressing this gap, this study analyzed 148 threads containing 6,240 notes from a learning science course at a public university over three years. Through clustering analysis, we identified productive and improvable KB inquiry threads recorded in the Knowledge Forum (KF) with productive threads, which are characterized by deeper cognitive efforts and more sustained discussion than improvable threads. Integrating three levels of analysis, namely frequency, lag-sequential analysis, and sequential pattern mining, we aim to comprehensively capture students’ emotional dynamics across different kinds of inquiry threads. Our study identified distinct emotional dynamics and constructed emotion evolution models for productive and improvable inquiry threads. Productive threads frequently exhibited transitions between negative emotions such as confusion, anxiety, and frustration, indicating their deeper cognitive engagement and suggesting that while students experienced challenges in reaching a consensus, they remained cognitively engaged in the inquiry. Conversely, improvable threads were characterized by sequences involving positive emotions like joy and curiosity, often appearing at the beginning of discussions or in threads that lacked depth, indicating that while initial interest was present, these discussions failed to evolve into meaningful inquiries. Emotional transitions from activating emotions (e.g., joy) to deactivating emotions (e.g., boredom) in improvable threads further suggest a disengagement from the discussion. These findings highlight the intricate emotional dynamics during learning activities and provide valuable insights for future research focused on enhancing productive discussions in CSCL environments through effective emotional regulation strategies.</div></div>","PeriodicalId":10568,"journal":{"name":"Computers & Education","volume":"238 ","pages":"Article 105395"},"PeriodicalIF":8.9,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study initially incorporated a customised IMRT, which supports teachers to communicate with a virtual administrator, to generate comments and refinements for classroom dialogue in an immersive and tangible way. A quasi-experiment was conducted with 60 primary school teachers to test its effectiveness. This study discovered that teachers participating in the IMRT-based training tended to exhibit greater self-efficacy in enhancing dialogic pedagogy compared to those who engaged in traditional training methods. Furthermore, these teachers' practical competencies concerning dialogic pedagogy increased dramatically. Specifically, they gained greater proficiency in managing elaborated, coordinated, and speculative talk. Under their skilful initiation of dialogue, students were more inclined to justify ideas, seek connections, explore possibilities, and engage in constructive conversations. Moreover, findings indicated that more positive correlations between teachers’ self-efficacy and their actual practice in the IMRT-based training group, especially with regard to dialogues involving complex ways of thinking.

The present study was designed to shed light on two theoretically plausible moderators of such learning by digital explaining: the modality of (oral) explaining (audio + visual vs. audio only) and learners' level of the personality trait of extraversion. We conducted two experiments with university students (<em>N</em><sub>Exp1</sub> = 114; <em>N</em><sub>Exp2</sub> = 247). All students first watched a lecture video about the topic “social norms” and were then randomly assigned either to (a) explain the content of the lecture to fictitious peer students in a video message (i.e., audio + video), (b) to explain the content of the lecture to fictitious peer students in a voice message (i.e., audio), or (c) to restudy the slides of the lecture video. No substantial differences were found between learning by digital explaining in a video or voice message, but learners’ level of extraversion significantly moderated the benefits of learning by digital explaining regarding deep-level knowledge. Learners with low levels of extraversion benefitted more from learning by digital explaining, whereas learners with higher levels of extraversion benefitted more from restudy. Surprisingly, we furthermore found that restudy fostered surface-level knowledge compared to learning by digital explaining, whereas learning by digital explaining was superior (Experiment 1) or at least equivalent (Experiment 2) concerning deep-level knowledge.

Using a design-based research approach, researchers and teachers of students aged 6–16 years co-designed a remote professional development program at a private school in Islamabad, Pakistan, during the COVID-19 pandemic. Using conjecture mapping, this study uncovered a mechanism through which mixed-reality simulation fostered teacher contingent responsiveness when nested within a carefully designed professional development ecosystem. We found that interleaved practice in mixed-reality simulation with varied discussion framings, combined with case studies and guided collaborative inquiry, supported teachers in changing their discussion framings, which influenced their contingent responsiveness. Our findings reinforced the crucial role of teachers’ intentional framing of the discussion in shaping their responsiveness. This finding extends the theorization of teacher contingent responsiveness beyond fast thinking (thinking in the moment) and slow thinking (knowledge-based reasoning) to additionally include prospective thinking (thinking ahead).
