Development of Geo Natural Resource-App Learning Media in Geography Subject in the 21st Century

Abstract

Learning media is developing rapidly along with technological developments. Teachers are challenged to continue to innovate and be creative in developing learning media. The purpose of this study is to develop a mobile learning application called GeoNatural Resource-App based on desktop as a learning medium in geography subjects. The development of GeoNaturalResource-App media follows the steps of ADDIE's development, which are as follows: (1) Analyze: analyze performance, student learning needs, and curriculum. (2) Design: the preparation of the content and display of the media is arranged by creating a storyboard. (3) Development: developing designs into prototypes and validation from material experts and media experts. (4) Implementation: applying valid media to teachers and students to determine the feasibility and effectiveness of the media. (5) Evaluation: analyze the results of comments and suggestions from validators and test subjects.  The results of the study show that the percentage of validation carried out by material expert validators is 88.33% and can be said to be feasible. The percentage of validation by media expert validators is 91.76% and can be said to be very feasible. The average percentage of all validators is 90.04% and can be said to be very suitable for use as a learning medium.
