Validity of PowerPoint-iSpring Learning Media Integrated Prompting Question on Acid-Base Titration

Nesya Firia, Guspatni Guspatni

Abstract


Acid-base titration is a difficult chemical concept for most students because it is abstract. The abstract concept require media that can display macroscopic, submicroscopic and symbolic representation to make student understand the concept. Powerpoint and iSpring can provide text, picture, audio, video, animation and quizzes to learning media to help student understand the abstract concept of chemistry. This study aims to determine the level of validity of the PowerPoint-iSpring learning media integrated Prompting questions on acid-base titration. This type of research is Design Research and uses the Plomp development model. The Powerpint-iSPring learning media integrated prompting questions were validated by 5 material expert validators and 3 media expert validators. The research instrument was a material validation sheet consisting of content validation and construct validation, and media validation sheet. The results of the validation data were analyzed using Aiken's V data analysis techniques. The results showed the validity value of the PowerPoint-iSpring learning media integrated prompting questions for content validity was 0 ,92. The average value for construct validity is 0.92 and for media validity is 0.99. Thus, it can be concluded that the PowerPoint-iSpring learning media integrated prompting questions is valid and can be proceed to practicality and effectiveness test.
