Usage of Mobile Application in Assisting Chemical Experiments

Abstract

ChemEx is a mobile application that is created to assist students in performing chemical experiments. Students who study Bachelor of Electronic Engineering majoring in Nanotechnology use chemical experiment to synthesise nanoparticles. Through observation, they lack of confidence during the nanoparticles synthesis because they were not involved in any chemistry activities after foundation. To overcome this issue, a mobile application called ChemEx is created using Android Studio. In ChemEx, the usage of apparatuses and instruments, lab safety, the concept molarity and dilution, as well as the data of chemicals are introduced. Pre and post-test are used to evaluate the effectiveness of ChemEx in helping the students. Besides this, feedback form is used to evaluate the satisfaction of students after using ChemEx. The pre and post-test results show that the students have improved their understanding in apparatuses, safety, molarity and dilution. In the meantime, feedbacks show students are satisfied using ChemEx.
