Content Validity of Digital E-Module Oriented on Problem Solving in Science Learning on States of Matter and Their Changes Topic

This study aims to analyse the level of validity of digital e-module teaching materials oriented towards problem solving for fifth grade elementary school students on the topic of the state of matter and its changes. The type of research used is development research using the ADDIE model which consists of five stages, namely analysis, design, development, implementation, and evaluation. The validity of the digital e-module was analysed using descriptive statistics. Data collection was carried out through a questionnaire technique using a validation sheet instrument arranged according to a Likert scale. The number of validators used in this study was four experts in the field of education and learning technology. The validity of the problem-solving-oriented digital e-module was assessed based on the construction aspects of the E-Module teaching materials and the material aspects. Furthermore, the expert validation data were analysed using Gregory's theory and equation and categorized into four categories, namely valid, quite valid, less valid and invalid. The results of data analysis on each aspect of the construction of the E-Module teaching materials showed a content validation coefficient value of 0.94 in the high validity category with a percentage of V value obtained of 94%, in the material aspect showed a content validity coefficient value in the valid validity category with a percentage of V of 90%. The average value is in the valid category. Based on the results of the analysis, it can be concluded that the Problem Solving-oriented Digital E-Module is declared valid and feasible to use. The implication of this study is that this problem-solving-oriented digital e-module can be a reference in developing digital e-modules for other themes or topics in science learning at the elementary school level. It can also be developed at different grade levels and subjects.
