Online learning usually lacks efficient face-to-face monitoring and leads to poor learning outcomes; in this case, students' self-regulated learning in an online environment matter. However, Self-Regulated Learning (SRL) status remains unclear for those with learning disabilities and how their working memory and processing speed affect self-regulated learning. A total of 147 undergraduate students were recruited from three public and four private universities in Taiwan to join this study, and they completed a self-reported questionnaire and several psychological measures. Our results revealed significant differences in SRL features between typically developing Chinese undergraduates and those with learning disabilities in an online environment. Compared to the students with learning disabilities, typically developing students outperformed in metacognitive skills, time management, environmental structuring, and persistence. Help-seeking was comparable between both groups. Working memory significantly contributed to SRL in all students, whereas processing speed only significantly influenced SRL in students with learning disabilities. The findings of this study have important implications for educators, researchers, and instructional designers aiming to optimize online learning experiences and support, especially from the perspective of SRL, for all students, particularly those with learning disabilities.</p></div>","PeriodicalId":48186,"journal":{"name":"Internet and Higher Education","volume":"62 ","pages":"Article 100947"},"PeriodicalIF":8.6,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140535346","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}

In addition, this experiment examined the influence of role assignment and timing on participants' social communication in AOD and the effects of timing on individual role performance in role-based discussion. A total of 114 participants in a blended course were randomly assigned to four experimental conditions: role-based pre-class discussion (<em>n</em> = 29), role-free pre-class discussion (n = 29), role-based post-class discussion (<em>n</em> = 28), and role-free post-class discussion (n = 28). The results showed that the role assignment strategy featured by initiator, supporter, and arguer has led to improved learning experiences in terms of affection, sense of community, and forum experiences, as well as enhanced social communication in AOD; while timing affected the enactment, contribution, and participation of assigned roles in role-based discussions. However, there was no significant interaction between the two AOD strategies. In general, role-based post-class AOD is recommended after face-to-face lesson because of the better learning experience and role performance.</p></div>","PeriodicalId":48186,"journal":{"name":"Internet and Higher Education","volume":"60 ","pages":"Article 100932"},"PeriodicalIF":8.6,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71435888","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}

Given the increasing presence of online classrooms in tertiary education, it is much needed to examine ways to encourage students to ask questions and increase their engagement. Despite the critical role of asking questions to enhance learning, little is known in research on promoting this behavior. Therefore, in this paper, we empirically tested the effect of nudging – a novel approach in education consisting of subtle interventions to change behavior – in online classrooms in tertiary education on question asking behavior, student engagement, and grades. In Experiment 1 (<em>n</em> = 1011), the teacher's virtual background prompted questions (<em>prompt nudge)</em>, while in Experiment 2 (<em>n</em> = 449), the teacher set a goal for the students to ask one question per session (<em>goal-setting nudge</em>). We found a trend towards a positive effect of the <em>prompt nudge</em> on questions, but not on grades. Exploratory analyses revealed this was driven by students who already asked many questions. We found no effect of the <em>goal-setting nudge</em> on any measure, nor any effect in either experiment on student engagement. The findings demonstrate that the <em>prompt nudge</em> can be a possible useful and easy to implement tool to encourage questions in the online classroom.</p></div>","PeriodicalId":48186,"journal":{"name":"Internet and Higher Education","volume":"60 ","pages":"Article 100931"},"PeriodicalIF":8.6,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71417361","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 aimed to enhance our understanding of how the CoI presences influence students' actual learning outcomes by incorporating learner empowerment as an essential learner characteristic. This study was conducted in two undergraduate courses that were abruptly shifted online due to the COVID-19 lockdown. Structural equation modeling was used to examine the relationship between the CoI presences, learner empowerment, and actual learning outcomes. The results show that learner empowerment has a direct and positive impact on students' actual learning outcomes, and partially mediates the relationship between CoI presences and learning outcomes.

We use a large dataset of online traces from 135 students who completed 10 successive courses (i.e., 1350 course enrollments) in a higher education program. The methods used in this study have shown the feasibility of using trace data recorded by learning management systems to unobtrusively trace and model the longitudinal learning strategies across a program. We identified three program-level strategy trajectories: a stable and intense trajectory related to deep learning where students used diverse strategies and scored the highest grades; a fluctuating interactive trajectory, where students focused on course requirements, scored average grades, and were relatively fluctuating; and a light trajectory related to surface learning where students invested the least effort, scored the lowest grades, and had a relatively stable pathway. Students who were intensely active were more likely to transfer the intense strategies and therefore, they were expected to require less support or guidance. Students focusing on course requirements were not as effective self-regulators as they seemed and possibly required early guidance and support from teachers.
