The development flipbook explainer of transformation geometry

This study aims to develop e-module teaching materials using a flip-book application in the transformation geometry course. In this study, an Explainer Flipbook will be developed. The flip-book that contains further explanations about the material written in the book, so that the ideas that are written in the book can be optimized. The method in this study was carried out using the Research & Development Plomp model, which is based on the objectives, which includes 4 stages, consist of, 1) Investigation stage, 2) Design stage, and 3) Construction stage, 4) Test, Evaluation and Revision stage. and Implementation. Based on the phases carried out, transforming geometry teaching materials are produced in the form of an explainer flip-book that is valid in content and language, is interesting, and practical.
