| 2024 | Preliminary Evaluation of Learning Analytics Dashboard for College Teachers' Online Professional LearningabstractWidely accessible online courses provide a feasible platform for teachers' continuous online professional learning. The learning analytics dashboard (LAD) provides fine-grained and actionable feedback that supports learners’ self-regulated learning. However, previous studies on LAD design and evaluation predominantly focused on student-facing LADs, with scarce attention on LADs designed for teacher-learners. This study introduces the LAD in an online learning platform for college teachers and conducts a preliminary evaluation with 18 participants. Results show their largely positive ratings on five criteria (e.g., perceived usefulness, ease of use, and behavioral changes) and offer feedback for further refinements of the LAD. This study will improve our understanding of LA-enabled teacher online professional learning and provide practical implications for designing and evaluating LA tools catered to teacher-learners.

| 2024 | Needs Analysis of Learning Analytics Dashboard for College Teacher Online Professional Learning in an International Training Initiative for the Global SouthabstractOnline courses enable wide access to educational resources and thus provide a feasible platform for cross-regional teacher professional learning. Learning analytics dashboards (LAD) can support online learners by providing fine-grained feedback generated from learners’ interactions with platforms. Nevertheless, most studies on teacher online professional learning focus on resource-rich and technology-advanced regions, with scarce attention to the Global South. Furthermore, existing studies on LAD design mainly target students’ learning, rather than teachers’ professional learning. Therefore, it is much needed to develop LAD for teacher-learners online professional learning in the Global South. Contextualized in an international online professional training initiative, this study conducted in-depth interviews with 42 teacher-learners from 19 countries in the Global South, aiming to identify their needs for 1) support on their self-regulated learning (SRL), and 2) potential LA components in dashboards. Findings indicated that teacher-learners needed support for self-regulated learning strategies, including motivation maintenance, time management, environment structuring, help-seeking, and self-evaluation. Nine LA features were identified to design the LADs to support SRL preliminarily. This co-designed LAD study with interviewees improved our understanding on the needs of college teachers in the Global South for LA support during their online professional learning, generating practical insights into needs-driven LAD designs.

| 2023 | Exploring Factors Limiting Participation in an Online Training Program for College Teachers from Developing CountriesabstractOnline video courses allow large-scale distribution of educational resources and thus provide a feasible platform for cross-regional teacher professional development (TPD). However, with most studies focusing on TPD using online video courses in developed countries, less attention was paid to factors influencing the online learning experience of teachers from less developed areas. Therefore, this pilot study aims at exploring predictors of 3471 college teachers' online learning engagement. First, the results of a multivariate linear regression (MLR) revealed that at the individual level, there was a significant positive relationship between teachers' age and learning duration. At the institutional level, participants from the partner institutions had longer learning durations. At the country level, there was a significant positive relationship between country literacy rates and learning durations. Then, another MLR on relationships between self-reported learning perceptions after taking the course and learning durations was conducted. Results showed that learners' prior knowledge was negatively associated with learning durations. There was a significantly positive relationship between “recommend this platform to others” and learning duration. The findings can inform us of the factors that may have been overlooked when supporting college teachers' online professional learning in developing countries.

| 2021 | Minority college students' engagement in learning activities and its relationships with learning outcomesabstractMinority college students' learning engagement is an important perspective for improving education equity and facilitating learning. Based on responses from a large-scale experience survey among Chinese college students, this study aims to explore minority students' engagement in nine learning activities and its relationship with learning outcomes, as well as their difference from overall student sample. Descriptive statistical analysis, single sample t-test, and multiple linear regression analysis were conducted. The results revealed: (1) Minority students' engagement in learning activities was low, especially in formal learning activities. (2) Interaction with teachers, engagement in arts activities did not predict minority students' learning outcomes, which was different from findings in the overall student sample. (3) Engagement in student organizations did not predict students' learning outcomes in either sample. Based on results, suggestions were discussed for improving students' learning engagement.
