Development and evaluation of a learning support robot for vector learning

Vectors studied in high school are a new concept that differs from those studied in previous scalars.Therefore, it has been pointed out that difficulties arise in the conceptual formation of vectors.This study aims to develop a learning support robot that can visualize vector information by robot movements, and to acquire vector concepts for students through classroom practice using the robot.The robot operates on a piece of imitation paper, marking the start and end points and connecting them with arrows to visualize the vectors.In a class using the robot, the student predicts the sum of the vectors, and the robot confirms it.A questionnaire was administered before and after the class.The results revealed significantly higher mean values when comparing the pre-and post-assessments.
