ABSTRACT-In this article, we review research on childrobot interaction (CRI) to discuss how social robots can be used to scaffold language learning in young children. First we provide reasons why robots can be useful for teaching first and second languages to children. Then we review studies on CRI that used robots to help children learn vocabulary and produce language. The studies vary in first and second languages and demographics of the learners (typically developing children and children with hearing and communication impairments). We conclude that, although social robots are useful for teaching language to children, evidence suggests that robots are not as effective as human teachers. However, this conclusion is not definitive because robots that tutor students in language have not been evaluated rigorously and technology is advancing rapidly. We suggest that CRI offers an opportunity for research and list possible directions for that work.
KEYWORDS-child-robotinteraction; social robots; language learning Using technology in early education has gained considerable attention as digital devices (e.g., smartphones and tablets) have developed and been integrated into children's lives (1). In this article, we spotlight one of the newest additions to the list of devices-social robots-and discuss whether research on child-robot interaction (CRI) can help children learn first and second languages.A social robot is "an autonomous or semiautonomous robot that interacts and communicates with humans by following the behavioral norms expected by the people with whom the robot is intended to interact" (2, p. 592). Social robots have been used to teach scientific knowledge, mathematics, social skills, computer programming, and language (3, 4). However, research on CRI has not been readily accessible to all those interested because the studies appear primarily in conference proceedings and journals dedicated to the field of robotics. Furthermore, these studies often focus on technical features of robots rather than educational concerns, such as whether and how robots can help young language learners.In this article, we summarize findings on CRI and evaluate them critically. First we discuss briefly why a robot may be useful for teaching language to children. Then we evaluate whether children enjoy learning language with a robot. In the main section of the article, we ask whether children can learn language from a robot. We analyze learning outcomes at three levels: whether robots are at all successful teaching language to children, whether they are more successful teaching language than other digital devices, and whether robots can teach language as effectively as human teachers. Although social robots have potential as a language teaching tool, evidence suggests that robots are not as effective as human teachers. However, we argue that researchers must continue exploring this issue because the educational benefits of robots have not been evaluated thoroughly and technology in robotics is advancing quickly.
