Together with the development of ubiquitous computing technology and robot technology, intelligent type robots are being utilized in many areas and the range is expected to become wider and wider. Among many service robots, the educational robots are being diversely studied in the field with the concept of r-Learning. Presently, teaching assistant robots require a lot of HRI studies prior to their practical use in the very near future and are not sufficient yet. Especially, the reactions of students based of the styles of robots (e.g. serious robot, playful robot) are very important in producing robot contents but there has been no case study on them. Therefore, in this study, the appearance of the IROBI was changed to become a teaching assistant robot and was used to test and compare elementary school students' interest, achievement and concentration depending on the styles of robot (playful, serious). The results showed that the interest was high in the group that had studied with the playful robot. The achievement however, did not show significant relations with the style of robot and that the concentration was high in the group that had studied with the serious robot.
