Salt hero: an interactive application for learning salt in chemistry

We introduce Salt Hero, an interactive learning application designed to support students in learning about salt. Salt is an ionic compound that results from the neutralisation reaction of an acid and a base, and is one of the fundamental topics when learning chemistry. The topic is often challenging to students as there are numerous equations of salt formation need to be identified and understood. Further, most students have constrained access to school chemistry laboratories thus limiting their opportunities to conduct practical experiments beneficial to their learning. Salt Hero allows students to conduct virtual experiments that simulates salt formation via its virtual lab anywhere and at any time. This article presents the production cycle of our award winning interactive learning application and its pedagogical considerations. User evaluations on Salt Hero yielded a high rate of user satisfaction and indicated that the interactive learning application is perceived as effective in enhancing student's learning experience of the topic.
