Abstract

Research has been carried out with the title Innovation Development of Android-Based Digital Teaching Materials on Colloid Systems Material. The purpose of this study was to develop an android-based digital teaching material colloidal system and to determine the level of validation of android-based digital teaching materials. The development of this digital teaching material uses the Borg and Gall research model. The development procedure includes 4 stages, namely: (1) Preliminary study, (2) Development, (3) Field Test, (4) Final Product Dissemination. At the development stage, the products that have been developed are then assessed by three experts, namely instrument experts, material experts and media experts. Furthermore, the field test phase is divided into two, namely limited field test and product feasibility test. In a limited field test, products that have been assessed by material experts and media experts are then revised and reassessed by peer reviewers in this case high school chemistry teacher. While on the product feasibility test, the results of the peer reviewers' revisions that were revised by the developer were then assessed by reviewers. The results of the expert's assessment of the questionnaire included the very good and feasible categories used in the field. The results of the assessment of material experts and the media on the feasibility of this digital teaching material have a very good category with the percentage of safety ideals respectively 92.67% and 93.016%. In the limited field testing stage by peer reviewers on digital teaching materials, scores were obtained with very good categories and overall ideal percentage of 89.86%. During the product feasibility test by the reviewer, the assessment results were included in the excellent category and the overall ideal percentage was 91.94%. Based on expert judgment, peer reviewers and reviewers of android-based digital teaching materials on colloidal system material are very suitable to be used as supporting chemical learning.
