Abstract

This study aims to determine the impact of using gadgets on high school students' learning motivation in high school chemistry lessons. The type of research used in this research is descriptive qualitative. Qualitative research is research that is intended to reveal symptoms as a whole and in accordance with the context or what they are through collecting data with a natural background as a direct source with the key research instruments themselves. So in this study the researchers conducted observations, interviews and documentation. The results of the study show that: 1) the use of gadgets among high school students, especially in chemistry lessons, is used as a communication aid in increasing student learning motivation such as the use of practicum videos and animations. But there are some students who often play games rather than study. 2) the positive impact of using gadgets, students are able to get information and communication easily while the negative impact of using gadgets during class hours can interfere with student learning concentration so that it can affect student learning behavior. Most students often open the internet and communicate for less useful things that can interfere with the learning process. So that it makes students' learning motivation decrease.

Abstract

AbstractThis study aims to analyze the needs before developing computational chemistry-based learning media on hydrocarbon materials. This research is classified as development research developed with the ADDIE model. It's just that the stage used in this study is only limited to the analysis stage. Data collection in research is carried out by literature study methods and field studies with research instruments in the form of questionnaires on learning media needs and interviews by teachers. The location of this study is SMA Negeri Modal Bangsa Arun. Based on the results of interviews with chemistry teachers, it was found that learning hydrocarbon material at the high school level requires more effort because students must understand molecular structure, chemical bonds, and atomic structure. This makes students less understanding of concepts microscopically and can also cause misconceptions. Then, the results of the needs analysis show that there are still limited learning media that support microscopic concepts, especially the shape of molecules in 3-D. Based on the results of this study, it can be concluded that it is necessary to develop computational chemistry-based learning media on hydrocarbon materials.
