The Triumph of Human-Robot Interaction: Employing Humanoid Robot to Boost Grammar Acquisition and Retention Among Iranian Young EFL Learners

Abstract

This paper examines the impact of employing an assistive humanoid robot in acquiring and retaining grammar among English as a Foreign Language (EFL) learners. To this end, forty-eight Iranian young male students (between 11 to 15 years old) were equally divided into three groups: RALL (Robot-Assisted Language Learning), GBLL (Game-based Language Learning), and the control group. While the teacher, the textbook, and teaching materials were identical in all groups, a set of similar games were played only in the RALL (with the participation of the NAO H21 robot) and GBLL groups. A 20-item grammar pre-test was taken at the beginning of the classes. Overall, a total of ten intervention sessions (each lasting for 60 minutes), 15 (each lasting for 90 minutes), and 15 (each lasting for 120 minutes) were respectively administered for the RALL, GBLL, and control groups. At the end of the treatments, the acquisition and retention of grammar were evaluated through immediate (at the end of class) and delayed post-tests (two weeks later), correspondingly. The results of descriptive statistics and ANOVA indicated that the RALL group outperformed the two groups in the immediate and delayed post-tests. The students in the RALL group had a very positive attitude toward robot presence in the class and scored higher on the post-test. This study suggests that RALL can be very beneficial in assisting teaching EFL classes. The results of the current innovative study can equally yield important implications for language education and social robotics fields and further contribute to providing clear evidence of the impacts of RALL on Iranian young learners’ English grammar acquisition.
