Development of an Application for Calculating Half-life Values in a Periodic Table

Abstract

The research aimed to develop an application for calculating the half-life of isotopes in the periodic table. The objectives were to 1) design the application for calculating the half-life of isotopes in the periodic table, 2) study the half-life of isotopes in the periodic table, and 3) compare the performance before and after using the application to calculate the half-life of isotopes in the periodic table. The mobile application development tool used in this research was easy to develop, requiring no programming skills or software installation. Content and data for research were collected from the internet and experts. The research process included studying the problem and its solutions, designing the application interface, evaluating the application's performance, which was evaluated by experts, and providing a questionnaire for the experimental groups, which were divided into two groups: a group that did not use the application and a group that did. The evaluation results of the application showed an overall mean (  = 3.66,  = 0.57) at a high level, and the satisfaction of the group that used the application had an overall mean (  = 3.58,  = 0.61) at a high level.
