Development of "Set and Logic" E-Book With Flip Pdf Pro

Abstract

The implementation of the learning system during the COVID-19 pandemic underwent a change in learning styles. Where, learning is usually done offline, during a pandemic, learning activities are carried out fully online. Reflecting on the need for online learning activities, namely teaching materials in digital form, the researchers conducted development research with the 4D development model (Define, Design, Develop, and Desseminate) from Thiagarajan (1974). This study aims to produce a product in the form of an E-book "Set and Logic" with the FLIP PDF PRO application which is suitable for use for students in the "Set and Logic" lecture. In this study, the research subjects were first semester students in class Dik-E 2021, the Mathematics Education Study Program, FMIPA Unimed. The quality of the development results is determined based on the criteria of Nieveen (1999), namely valid, practical and effective. The results of the research on the development of this E-book, according to experts, show that the E-book "Set and Logic" developed has very feasible or valid criteria with an average score of 4.64, which is based on the results of the assessment of material expert validators and media expert validators. And to see the practicality that is based on the results of the positive response of students with the acquisition of a percentage of 85.71%. Meanwhile, to see the effectiveness of the development of this E-book is based on the results of the normalized gain index value. From the research data, the gain value is 0.74, which is based on the pretest (43.2) and posttest (85.3) values. This indicates that the E-book is effective for use in the "Set and Logic" course. Thus, this E-book is included in the appropriate criteria and can be used in the lecture activity "Set and Logic".
