The development of powerpoint optimization training module as learning media: A validation study

Abstract

Module is a complex teaching material that allow students to learn independently. Qualified module is produced through validation stages. Validation is a very important process in teaching material development so that it can be used practically and effectively. This study aimed to determine the validity of the training module of PowerPoint optimization as a learning media. The type of this research is Research and Development with 4D model (Define, Design, Develop, and Disseminate). Research data is the result of expert evaluations regarding product validation such as content validity, construct validity, and language validity. Validation is a sequence of activities at the development stage. In conducting validation, it must also be ensured that the instrument used to assess the product is also valid to avoid bias when evaluating the product. Validation data were analyzed using Aiken’s V. The results of the study showed that the module developed was in the valid category with the average of Aiken’s V coefficient > 0,6 therefore, it could be used at the trial stage.
