An AI-based English education platform during the COVID-19 pandemic

Abstract

This study examines whether the use of AI-Pengtalk, an AI-based Conversational English programme, provided by a broadcasting company (EBS) that specializes in public education can significantly improve conversational English skills and bridge the English language proficiency gap associated with parental socioeconomic status. Over the course of four weeks from April 27 to May 22 in 2020, 108 fourth-grade classes in 54 elementary schools voluntarily participated in this experiment. Two classes in each school were designated as a treatment group and a control group. For the treatment group, a tablet installed with a pilot version of AI-Pengtalk was provided and students were encouraged to make use of the programme. Two sets of surveys and English tests were placed pre and post hoc. After 4 weeks, test scores, log files, and survey responses of participants were analysed. A series of DID analyses demonstrate that the use of AI-Pengtalk improves the treatment group's self-evaluation of their English abilities, confidence in using English, preference on English itself, and amount of time spent on studying English during the pilot experimental period compared to the control group. When other variables were controlled, the use of AI-Pengtalk also helped the treatment group achieve higher test scores. This study implicates that the use of smart English education like AI-Pengtalk may especially be able to better compensate for academic setbacks caused by low parental SES or, in the case of English learning, the reluctance to converse in English with other students.
