Development of Flip PDF-Assisted Scientific Approach E-Modules to Enhance Mathematical Understanding in Circle Topics for Grade VIII Students

The background of this research is the limitation of e-modules that are in accordance with the abilities of students who have difficulty in learning mathematics. This causes the low mathematical understanding skills of students. The goal of this study is to create an e-module based on the scientific approach assisted by flip pdf on circle material that is able to facilitate the mathematical understanding skills of grade VIII students. The development procedure is guided by the ADDIE model. This research was only conducted until the small group trial with subjects consisting of 10 students of SMPN 35 Pekanbaru grade VIII. Data was obtained by utilising interview and questionnaire techniques. The instruments used in data collection were validation questionnaire and student response questionnaire. The findings of the research obtained that e-module have an average validity of 3.52 which is classified as very valid. Meanwhile, the practicality of e-modules is classified as very practical with an average of 3.39. Thus, the e-module produced has met the requirements of validity and practicality, so that it is worth it for use by grade VIII junior high school / MTs students.
