<![CDATA[Students' chemical literacy regarding the topic of acids and bases remains relatively low, as this subject requires an integrated understanding of macroscopic, microscopic, and symbolic levels. Therefore, this study aimed to design an "Electronic Chemistry Magazine" (E-Chemagz) on acids and bases a valid and practical resource to enhance the chemical literacy of Phase F (high school/Islamic high school) students. The study employed the Educational Design Research (EDR) methodology, following the Plomp model, which resulted in the development of a four prototype (Prototype IV). The prototype development phase adhered to a formative evaluation process, consisting of self-evaluation, expert review, one-to-one evaluation, and small-group evaluation. The validity assessment was conducted by a panel of experts, including three lecturers from the Department of Chemistry at the Faculty of Mathematics and Natural Sciences (FMIPA) of Universitas Negeri Padang (UNP) and two chemistry teachers from a public high school in Padang. The practicality assessment involved two chemistry teachers and nine Phase F students from a public high school in Padang. Data were collected using validity and practicality questionnaires. Validity results were analyzed using Aiken’s V formula, while practicality results were analyzed based on the percentage of the product's practicality achievement scores. The findings indicate that the Aiken’s V values for each aspect ranged from 0.8 to 0.9, falling into the "valid" category. Furthermore, the average practicality scores provided by the teachers and students were 93.17% and 91.15%, respectively, placing the resource in the "highly practical" category. These assessment results demonstrate that the E-Chemagz on acids and bases is both valid and practical for improving the chemical literacy of Phase F high school students. Consequently, this E-Chemagz resource is ready to proceed to an effectiveness test to measure its impact on enhancing the chemical literacy of Phase F students.]]>
