This study discusses students’ responses and perceptions on the e-book of Local History of West Java (Indonesia) developed by the researchers. It uses a Research and Development approach and experimental method. Data collection techniques used in this study are observation, interviews, and focus group discussions with interactive model data analysis. The research subjects were students and teachers of high schools in West Java. They were taken as the subjects as they can represent the region. The History E-book is, however, published on ebooksejarah.id page while the system was developed by using SDLC (Software Development Life Cycle) Waterfall model. The results of the study indicate that the components of the e-book on the aspects of the materials, presentation, and completeness are overall suitable to be used by students. The materials are considered to be still inapplicable and not contextual. Further, they are still lack of latest issues as well as photos/illustrations. The study of student responses on the e-book reinforces that the zoomers (those belong to Generation Z) prefer to digital learning media because their social life belongs to the online world. Local history e-books should better adapt to the learning style of Generation Z, who prefer visuals and hands-on experiences to reading texts. Thus, e-book development needs to be equipped with various learning media in short audios and video explainers, animations, and infographics.

The vast technological development affects every layer of people’s daily life, including Education. However, Indonesia’s tertiary education status quo has not exhibited any rapid development in information technology-based learning media. This study aimed to develop and identify the effectiveness of Basic Pedagogy Material online learning material in improving students’ outcomes in pedagogy. It applied R & D design with a waterfall development model on second-semester students in Universitas Negeri Semarang, Indonesia, during the educational year of 2020/2021. The data collected through interviews, observation, questionnaire, scale, and test were analyzed using independent t-test and n-gain. The findings indicated a significant difference between the average score before and after students used the Basic Pedagogy Materials mobile learning application during the learning process. Therefore, the mobile learning application developed effectively improves students' learning outcomes in pedagogy subjects effectively.
