Abstract
In today's digital era, 4C skills (Critical Thinking, Communication, Collaboration, and Creativity) are essential competencies that students must master to face the challenges of the 21st century. However, complex and abstract physics learning often makes it difficult for students to develop their 4C skills. The use of electronic teaching materials can be an effective solution in facilitating the formation of students' 4C skills through more interactive and contextual learning. This study aims to determine the trends and focus of research related to electronic open materials to see students' 4C skills in physics material. The method used is bibliometric analysis. The population of this study was 1000 articles whose data were searched using the Publish or Perish (PoP) application from 2018-2023, so that 124 articles were obtained as samples that met the keyword criteria. The data is stored in Microsoft Excel as data processing material and stored in RIS form for use in VOSviewer software to obtain mapping in searching for publication trends.
