Data were collected through interview guidelines, questionnaires for material experts and media experts, students who responded to questionnaires, and questions’ tests. The beta test was carried out through a beta-1 test involving 30 students and a beta-2 test involving 27 students of Vocational High School, Lembang, Indonesia for the 2020/2021 academic year. The alpha test was carried out by seven content experts and two media experts. The validation test performed was an alpha test and a beta test. Product tests were performed at the production stage to assess the feasibility of the e-module. This e-module development focuses on the development design phases of Alessi & Trollip (2001), which consist of three stages, namely: the planning stage, the design stage, and the development stage. Some of the researchers are both practitioners and researchers in the research.

In this study, action research techniques were used. This study aims to create an e-module based on Sigil software on enumeration principles, as well as to examine the effects on self-regulated learning (SRL) using the e-module.

In the delivery of content, it is important to have multimedia elements so that the learning material delivery can be well received by students.
