Computer-supported collaborative concept mapping (CSCCM), as one of the computer-mediated instruction and learning strategies, has been used to foster collaborative knowledge construction (CKC). Previous research has characterized groups based on final knowledge artifacts, products, or performances, rather than the temporal, process-oriented characteristics generated during the collaborative learning process. To fill this gap, this research clustered groups into distinct clusters based on the collaborative discourse data by using agglomerative hierarchical clustering approach, and examined the process characteristics of different clusters and associated performances. Four clusters were identified and labeled. Cluster 1, the high-performing cluster, was characterized as the actively-engaged, idea-centered, consensus-achieved, and socioemotional-engaged cluster. Cluster 2, the low-performing cluster, was characterized as the inactively-engaged, information-shared, goal-oriented, and reflection-revolved cluster. Cluster 3, the medium-performing cluster, was characterized as the inactively-engaged, problems-unsolved, and reflection-revolved cluster. Cluster 4, the medium-performing cluster, was characterized as the actively-engaged, idea-centered, and goal-oriented cluster. Based on the results, this research proposed instructional strategies and assessment implications for improving CSCCM research and practice.

Peer feedback is regarded as playing a vital role in fostering preservice teachers’ noticing and reasoning skills during technology integration. However, novices in particular (e.g., pre-service teachers) tend to provide rather superficial feedback, which does not necessarily contribute to professional development. Against this background, we developed an online video-annotation tool, LiveFeedback + , which allows for providing peer feedback on the quality of technology integration during microteachings in a fine-grained manner. Applying a design-based research approach (2 design cycles, N = 42 pre-service teachers, quasi-experimental interrupted time-series design), we investigated whether the addition of prompts (Cycle 1) and strategy instruction combined with prompts (Cycle 2) contributed to the quality of peer feedback. Contrary to our predictions, piecewise regressions demonstrated that pre-service teachers provided more feedback comments with superficial praise and fewer feedback comments with substantial problem identification and solutions when prompts were available. However, when pre-service teachers were explicitly instructed in strategy use, the reasoning during peer feedback could be enhanced to some extent, as pre-service teachers provided less praise and more problem diagnosis in feedback comments when strategy instruction was available. These findings suggest that the addition of strategy instruction that explicitly models adequate feedback strategies based on prompts can help overcome mediation deficits during peer feedback in technology-based settings.

With continued growth in online learning, motivation remains a key factor in persistence and achievement. Online mathematics students struggle with self-regulation and self-efficacy. As reported by Ryan and Deci (Self-determination theory: basic psychological needs in motivation, development, and wellness, Guilford Press, 2017, https://doi.org/10.3233/EFI-2004-22201), in their well-established self-determination theory, contended that satisfying the psychological needs of autonomy (involving self-regulation), competence (involving self-efficacy), and relatedness (involving a sense of belonging) creates a suitable environment for integrated extrinsic and intrinsic motivation to thrive. The purpose of this action research was to implement a self-determination theory-based online unit for mathematics students to improve their motivation levels. A convergent mixed methods action research design was employed to identify changes in the levels of autonomy, competence, and relatedness of the participants in an Algebra 2 course (n = 50) at a fully online school in the northeastern United States. Results from the motivation questionnaire and student interviews indicated a significant increase in competence and relatedness after completing the intervention. While no significant increase in autonomy was evident in the quantitative results, the qualitative findings showed some support for improved autonomy. Recommendations for online mathematics course design to support increased motivation are provided.
