Pengembangan Aplikasi Media Pembelajaran Berbasis Android pada Materi Larutan Elektrolit dan Nonelektrolit

Abstract

The purpose of this study is to develop the Melonit applications an Android-based learning media on electrolyte and non-electrolyte solutions, and disclose the level of validity of the developed product regarding the validity of the content, construct and media. This type of research is Educational Design Research applying the Plomp development model, which consists of three stages, namely preliminary research, prototyping stage and assessment stage. The research instruments used were in the form of content validity questionnaires, constructs and media and one to one evaluation interview sheets. The results of processing the content and construct validity data were obtained at 0,89 with a valid category. Meanwhile, the validity of the media was obtained at 0,94 with a valid category. Research on android-based learning media applications that have been developed is valid, so that further research can be carried out on the practicality and effectiveness of the applications that have been developed.

Development of android-based learning media applications on mole concept topics for high school students

“…Teachers have never used android-based learning media applications in their lessons. Some literature states that android-based learning media applications have been developed on electrolyte and non-electrolyte solutions, thermochemistry, basic laws of chemistry, atomic structure, periodic system, and chemical equilibrium [6,7,8,9,10,11]. It is concluded that the android-based learning media application is valid for learning.…”

“…One of the abstract chemical materials is salt hydrolysis material. Abstract chemical concepts will be easier to understand by involving three levels of chemical representations, namely macroscopic, submicroscopic and symbolic representations (Sagita et al, 2018), (Yani et al, 2019), (Rachmawati et al, 2021), (Utari & Azra, 2022), (Adawiyah & Azra, 2022). Learning by applying chemical multirepresentations provides facilities for meaningful or in-depth learning to occur (Sagita et al, 2017), and is able to improve understanding of chemical concepts and chemical problem solving (Sari & Helsy, 2018).…”
