Investigating the Effect of a Robotic Tutor on Learner Perception of Skill Based Feedback

چکیده
In this paper we investigate the effect of different embodiments on perception of a skill based feedback (a basic open learner model) with a robotic tutor. We describe a study with fifty-one 11-13 year old learners. Each learner carries out a geography based activity on a touch table. A real time model of the learner’s skill levels is built based on the learner’s interaction with the activity. We explore three conditions where the contents of this learner model is fed back to the learner with different levels of embodiment: (1) Full embodiment, where skill levels are presented and explained solely by a robot; (2) Mixed embodiment, where skill levels are presented on a screen with explanation by a robot; and (3) No embodiment, where skill levels and explanation are presented on a screen with no robot. The findings suggest that embodiment can increase enjoyment, understanding, and trust in explanations of an open

Error Recovery by the Use of Sensory Feedback and Reference Measurements for Robotic Assembly
Industrial robots need instrument or parts transport to do which requires coordinate to show the robot’s instrument, parts and body. When investigating the robot location, we are usually interested in measuring its location relative to a reference coordinate system. In this system it is attempted to make the assemble direction smaller by designing the sensor board and making use of an instrumen...
متن کاملThe Effect of Scaffolded Written Corrective Feedback on Iranian EFL Learners’ Writing Quality: An Activity Theory Perspective
With the latest paradigm shift in SLA from Cognitivism to Sociocultural Theory (SCT), more studies are carried out to investigate the efficacy of Written Corrective Feedback (WCF) through a social and cultural lens. A more recent offspring of SCT is Activity Theory which provides an explanatory framework for scrutinizing an activity in a social setting. The present study aimed at investigating ...

متن کاملTeacher Perspectives on the Potential for Scaffolding with an Open Learner Model and a Robotic Tutor
This paper considers the potential for scaffolding learning in openended learning environments using a robotic tutor and an open learner model. While we expect this approach to be more broadly applicable, we here illustrate with a map-reading activity in geography and/or environmental sciences. The paper presents issues raised in open-ended teacher interviews, which suggest real possibilities f...
