The Effects of Three Instructor Participatory Roles on a Small Group’s Collaborative Concept Mapping

Collaborative concept mapping, as one of the widely used computer-supported collaborative learning (CSCL) modes, has been used to foster students’ meaning making, problem solving, and knowledge construction. Previous empirical research has used varied instructional scaffoldings and has reported different effects of those scaffoldings on collaboration. To further examine the effects of instructional scaffoldings, this research implements three different instructor participatory roles (i.e., cognitive contributor, group regulator, and social supporter) to support online collaborative concept mapping (CCM). We use multiple learning analytics methods to examine the group’s CCM processes from the social, cognitive, and metacognitive dimensions, supplemented with assessments of the concept maps. The research reveals different effects of three instructor participatory roles on the group’s collaborative behaviors, discourses, and performances. When the instructor engaged as a cognitive contributor, the student group achieved a lowly-interactive, low-level metacognitive engagement and behavior-oriented knowledge construction; when the instructor engaged as a group regulator, the student group achieved a socially-balanced, high-level metacognitive engagement and behavior-communication-interrelated knowledge construction; and when the instructor engaged as a social supporter, the student group achieved a highly-interactive, medium-level metacognitive engagement and communication-oriented knowledge construction. Based on the results, this research proposed pedagogical, analytical, and theoretical implications for future empirical research of CSCL.

Supporting interdisciplinary collaborative concept mapping with individual preparation phase

Concept mapping facilitates the externalisation and internalisation of knowledge by individuals during collaborative knowledge construction. However, not much is known about the individual and collaborative learning processes during collaborative concept mapping (CCM) in interdisciplinary knowledge construction. Premised on literature on collaboration scripts to scaffold the collaboration process, this study investigates the effect of an individual preparation phase prior to collaborative work on the epistemic and social processes of knowledge co-construction, as well as the degree of interdisciplinary knowledge integration in collaborative concept mapping. A total of N = 42 third year university students were put into one of the two experimental conditions: with individual preparation phase (WIP) and without individual preparation phase (WOIP). Students worked on a collaborative assignment to integrate interdisciplinary knowledge in collaborative concept mapping. Data for analysis was derived from audio recordings of the collaborative discourse in both experimental conditions. Chi-square test was conducted to investigate if there were significant differences between the effects of WIP and WOIP on the epistemological and social dimension. Findings showed that groups in the WIP condition showed significantly more verification, clarification and positioning statements in the epistemic dimension and also significantly more integration-oriented and conflict-oriented consensus building in the social dimension as compared to groups in the WOIP condition. On the degree of interdisciplinary knowledge integration, independent sample t-tests showed that there was no significant difference for concepts, domains and cross-links between the two experimental conditions. However, there was significant difference in types of cross-links for the CCMs in the WIP condition.

Effect of collaborative concept mapping teaching strategy on students’ achievement in chemistry in selected secondary schools in Kenya

In Kenya, the fundamental challenge facing chemistry teaching in secondary schools is how to enhance students’ conceptual understanding; a need for meaningful learning. The challenge has led to students’ underachievement in chemistry in national examinations. Research findings indicate that teaching method is a crucial factor affecting students’ learning and achievement. The present study investigated the effect of Collaborative Concept Mapping (CCM) teaching strategy on students’ achievement in Chemistry. Solomon Four Group quasi-experimental research design was used in the study. Four co-educational secondary schools were randomly selected for the study from secondary schools in Bomet District, Kenya. Students in experimental groups were taught using CCM teaching strategy for 8 weeks while the rest were taught using conventional teaching methods. Mole Concept Achievement Test (MCAT) was administered to determine students’ achievement on the topic of “mole concept”. Results of the study showed that CCM as a teaching strategy had no significant effect on the achievement among students of low and average academic abilities as well as those of higher academic abilities at 0.05 α significance level.
