Lopez 1 Tagoloan Community College, Baluarte, Tagoloan, Misamis Oriental, Philippines The study of electric circuits, which requires some technical skill, appears to be difficult and challenging during a pandemic not just for electronics technology students but also to the instructors handling such course. Having observed this problem in modular learning, the researchers decided to conduct a study which involves the use of mobile simulation application ¨C the EveryCircuit. This study focuses on the effect of using the simulation application on the procedural knowledge of students. An experimental research using the single group pretest-posttest design was utilized in this study. The first activity was the administration of the 40-item pretest, crafted and evaluated by skilled and experienced Electric Circuit instructors/engineers. At the end of the intervention, the posttest was administered, and grades were recorded. Data collected were analyzed using One-Way ANOVA, run through MS Excel - Data Analysis. Results of the study showed that there is a significant difference between the pretest and posttest scores of the students in favor of the posttest [P-value = 0.02121, < 0.05]. The pretest mean score of 0.25 which has increased as shown in the mean posttest score (1.45) of the students implies that the use of mobile simulation application may have played a significant role in enhancing studentsĄŻ procedural knowledge. Hence, the researcher recommends the use of any other simulation applications not only in electric circuits but also to other topics or even to the other disciplines, when applicable. http://pubs.sciepub.com/education/9/8/4/education-9-8-4.pdf simulation application procedural knowledge EveryCircuit electric circuits electronics technology
