Research trends in the use of E-books in English as a foreign language (EFL) education from 2011 to 2020: a bibliometric and content analysis

This study aims to identify the bibliometric outcomes of articles and research trends in specific areas. This study revealed research on the use of e-books for EFL education published in selected journals of the Web of Science from 2011 to 2020, and discusses the trends of the top-cited countries, journals, the most used keywords, and the popular subjects, learning strategies, target skills, and the research outcomes. A total of 53 selected articles were manually and systematically analyzed. The results revealed that the most productive country was Taiwan, and the most cited journal was Computers & Education. The most used keywords were "engagement." " The bibliometric analysis can be reflected in the content analysis as preschoolers and elementary school students were the most common participants, guided learning were the most frequently used strategy, and the main target skill was reading. This review study provides an overview of the research agenda for the last 10 years, and highlights the trends in the field by analyzing relevant past research. When the use of e-books in EFL education studies was examined, reading comprehension, teaching/learning strategies, and learning engagement were found to be crucial in the studies. Therefore, there is a need to develop more useful features of e-books to support EFL teaching practices. It is therefore suggested that future research focus more on pedagogical aspects and e-book feature development.
