The Effects of Three Scaffoldings on Computer-Supported, Robot-Assisted Collaborative Programming in Higher Education

摘要

Computer-supported, robot-assisted collaborative programming (CSRACP) is a computer-supported collaborative learning (CSCL) mode used in programming education. CSRACP allows students to work in groups with the support of robots to achieve programming functions and complete complex tasks. This research applied multimodal learning analytics (MMLA) to examine the effects of three pedagogical scaffoldings (i.e., conceptual, task-oriented, and meta-cognitive scaffolding) on student pairs' CSRACP activities in higher education. The results revealed that students under conceptual scaffolding had the low-level cognitive engagement, task-oriented regulation, and low-level socio-emotional expression, with the lowest programming task score; students under task-oriented scaffolding had the operation-driven cognitive engagement, observation-oriented regulation, and low-level socio-emotional expression, with the highest programming task score; and students under meta-cognitive scaffolding had the communication-driven cognitive engagement, exploration-oriented regulation and high-level socio-emotional expression, with the medium programming task score. Based on these findings, pedagogical and analytical implications were proposed to promote CSRACP in higher education.
