Comparing a Humanoid Tutor to a Human Tutor Delivering an Instructional Task to Children

Paper i proceeding, 2015

This paper presents a study that compares a humanoid robotic tutor to a human tutor when instructing school children to build a LEGO house. A total of 27 students, between the ages of 11-15, divided into two groups, participated in the study and data were collected to investigate the participants' success rate, requests for help, engagement, and attitude change toward robots following the experiment. The results reveal that both groups are equally successful in executing the task. However, students ask the human tutor more often for help, while students working with the robotic tutor are more eager to perform well on the task. Finally, all students get a more positive attitude toward a robotic tutor following the experiment, but those in the robot condition change their attitude somewhat more for certain questions, illustrating the importance of real interaction experiences prior to eliciting students' attitudes toward robots. The paper concludes that students do follow instructions from a robotic tutor but that more long-term interaction is necessary to study lasting effects.
