This study was motivated by several issues, namely (1) students have low reading comprehension skills, making it difficult for them to understand the content of the text (2) students find it difficult to read long texts (3) students are unable to understand the content of the text because the teaching materials used are not interesting, as they consist only of textbooks and supporting teaching modules that are not appealing. This study aims to develop E-module teaching materials based on the quantum reading learning model to improve students' reading comprehension skills in narrative texts in fourth grade elementary school that are valid, practical, and effective for use as teaching materials in the learning process for fourth grade elementary school students. This study is a research and development (R&D) study using the 4D method (define, design, development, dissemination). The results of the study indicate that the E-module teaching materials based on the quantum reading learning model for students' reading comprehension potential are highly valid, with a percentage of 81.5% in terms of material, media, and language. From the practicality test, the E-module teaching materials assisted by the quantum reading learning model for students' reading comprehension potential obtained a very practical criterion with an average score of 88.33% from teachers and 82.95% from students based on the aspects of use, visual appeal, and benefits. The results of the learning effectiveness test in class IVA had an average score of 88.39% with a very effective criterion. Thus, it can be concluded that the E-module teaching materials developed by the researcher are valid, practical, and effective for use by students in the learning process.
