I believe that the decision to learn or not to do so ultimately depends on the each learner. From primary and secondary education, teachers have been providing various interventions for learners’ learning, but in the end, it is the learner’s problem to decide whether or not to learn and to act on it. But It is the desire of teachers to support learners’ decision-making and promote self-regulated learning. This research project aims to design, develop, and evaluate a learning dashboard that activates metacognition, one of the elements that support learners’ decision-making. This research is funded by the JSPS Grant-in-Aid for Scientific Research, International Collaborative Research Acceleration Fund (B), in collaboration with Dr. Stephanie Teasley, University of Michigan.
