Android-based tutorial: Improving students digital literacy in mathematics programming

Abstract

Abstract The purpose of this research is the development of making media tutorials based on Android mathematical applications (Wolfram Alpha, Geogebra, and Matlab). This tutorial media is stored online and displayed through Google Site pages. The development used the Plomp model that has four-phases, namely the initial investigation, the design, the realization/construction, the testing, evaluation, and revision. Before making a media tutorial, the media tutorial was validated by two material experts. This prototype was tried for students in a limited way to see the practicality of using media and to be an evaluation for researchers. The conclusion from the media tutorial is considered feasible if it meets 1) the element of validity with the average results obtained from the material validation sheet 88.5% and 83.5% media experts; 2) it seems that the effectiveness of complete material from limited tests is 88.17% and field tests are 82.81%; and 3) the results of the questionnaire responses were seen from students after using the tutorial media on a limited test showed 79.33%, and in the field, the test showed 78.23%, the achievement of reinforcement using digital literacy. The acquisition in this study, sharpening digital literacy using tutorial media, is 71.11% categorized.
