Lectures are required to innovate in their learning by utilizing current technological developments. Producing an electronic module is one way that can be done to support mathematics learning. The purpose of this study was to determine the level of validity of the flipbook-based e-module on the material of analytical geometry of two dimensions. This study is a Research and Development (R&D) study with the PLOMP development model. This research uses a descriptive approach to explain the validity of the emodule. The instrument used is a validation questionnaire sheet and has been validated by three expert validators. Researchers conducted a validation sheet analysis to determine the quality of the e-module developed. The average percentage of the overall validation results from experts obtained a value of 92.5% with a very valid category. So, the flipbook-based e-module is very suitable for use as a teaching material for analytical geometry of two dimensions courses because it meets the assessment criteria. © 2026 Author(s).
