<![CDATA[This research is motivated by the limited use of interactive digital teaching materials in biology learning, especially on the human reproductive system material, so that students are less actively involved in the learning process and have difficulty in understanding the concept in depth. This research uses a development method (research and development) which is limited to the product validation stage with a quantitative descriptive approach focused on product validity analysis with the aim of determining the level of validity of problem-based learning-based e-modules on the human reproductive system material. The resulting product is a problem-based learning-based e-module compiled using Canva and presented in the form of a flipbook. The data sources in this study consist of material expert validators and media expert validators who provide an assessment of the validity of problem-based learning-based e-modules on the human reproductive system material. The research data were obtained through a validation questionnaire given to the validators using a Likert scale, while the data analysis technique was carried out descriptively quantitatively by calculating the percentage of the product validity level. The results showed that validation by material experts obtained a percentage of 92.5% with a very valid category, while validation by media experts obtained a percentage of 82.5% with a very valid category. Based on the validation summary, an average percentage of 87.5% was obtained, categorized as highly valid. Based on these results, it can be concluded that the problem-based learning e-module on the human reproductive system is highly valid and suitable for use as a biology teaching material.]]>
