VALIDITAS E-MODUL BERBASIS PROBLEM SOLVING PADA MATERI PROGRAM LINEAR KELAS XI SMA/MA

Abstract

This study aims to produce teaching materials in the form of e-modules based on problem solving based on linear program material for class XI SMA/MA. The reason is that the use of technology in learning is not optimal and the users of teaching materials modified by learning methods are limited. This type of research is Research and Development (R&D) using a 4D research model (Define, Design, Develop, Disseminate). This research was only carried out up to level 3, which is only up to the validation stage by experts without direct trials to the field. The data in the study were collected by questionnaire. The instrument used is a validation sheet by an expert. Data were analyzed by descriptive analysis. The data obtained is qualitative data and then the data is converted into quantitative data using MSR. From the validation of media experts, they obtained an average assessment of 81.32% with very valid criteria and for material expert validation, they obtained an assessment of 71.94% with valid criteria. The validation results show that the teaching materials developed are declared to be very valid and feasible to be tested in the field.
