Pengembangan Bahan Ajar E-modul Matematika Berbantuan Flip Pdf Professional Pada Materi Peluang Kelas VII SMP

This study was aimed at know the result of validity and practicality of developing mathematics teaching materials in the form of e-modules with the assistance of flip pdf professional on probability materials for class VIII SMP. The type of development research used the ADDIE model which consists of 5 stages, namely analysis, design, development, implementation, and evaluation. The research instrument used was a validation sheet with data collection techniques using a Likert scale and Guttman scale, and student response questionnaires using a Likert scale. The object of this research is mathematics e-modules teaching materials with the assistance of flip pdf professional on probability materials for class VIII SMP. The subjects of the trial were limited to small groups consisting of 12 students of class VIII SMP. The e-modules were validated by three validators, consisting of two Mathematics Education Lecturers from the Faculty of FKIP UIR and one mathematics teacher at SMP Negeri 22 Pekanbaru. The validity and practicality data were analyzed by determining the average of each assessment. The results of the study show that (1) the assessment of e-modules on the feasibility aspect of presentation using the Guttman scale, was obtained an average of 100% with very valid criteria, and on the media, material, and language aspects using a Likert scale, was obtained an average of 86.11% with very valid criteria; (2) the results of the practicality test based on the student's assessment of the student response questionnaires obtained an average of 95.39% with very practical criteria. Therefore, the conclusion to be drawn is that the mathematics e-module teacing materials assisted by flip pdf professional on probability materials of class VIII SMP were tested for their validity and practicalit
