E-Book Learning Research in Physics Education During the Last Five Years: A Review and Bibliometric Study

E-Book Research Increases every year consistently and has an excellent opportunity to be developed. This study aims to examine the type of document, the author's keywords, the country's contribution to learning about the subject of e-books in physics, and potential future research topics related to e-books. Through bibliometric analysis, a literature review is used in this research method with the help of Publish or Perish (PoP) software and Vosviewer to find articles. The data source was obtained from the Google Scholar database, which obtained 13,200 articles in 2017-2021 with the keywords "E-Book Physics Education". In the meantime, the Scopus database found 21 publications with the term "E-Book Physics" from 2007 to 2021. The results of the bibliometric analysis show that the trend of research topics and the contribution of Indonesian researchers is still relatively lacking, but the highest publication contribution by Indonesia. This is a challenge for future research to prove the extent to which the existence of E-Books can continue to be developed. Additionally, there are suggestions for research areas in learning with keywords, one of which is STEM. Therefore, E-Books can be used with a STEM approach to enhance students' learning abilities, particularly in understanding physics, and be used in subsequent studies.
