PhET Simulation, Academic Performance, Balancing Equations


The study assessed the effectiveness of PhET interactive simulation as a tool in improving the academic performance of students on balancing chemical equations, which is the least mastered skill in the 4th quarter of grade 10 Science. The subjects of the study are 8 males and 12 females Grade 10 students who were purposely selected for the study. The instruments used in the study were the validated 15-item pretest and the posttest from the Regional Test Item Bank.  The items of the test were purely balancing of chemical equations aligned with the learning competency on how to apply the mass conservation principles to chemical reactions, particularly the skills of balancing chemical equations of (in) Grade 10 Science K-12 curriculum. Moreover, the researcher utilized appropriate statistical tools such as the frequency distribution, mean, percentage, and t-test. The paired sample t-test revealed that there is a significant difference between the students' performance before and after the implementation of the PhET interactive simulation. This is established through the t-value of 15.28, which is greater than the t-critical value of 1.729 (15.28>1.729), and a probability value (p value) of .001, which is less than the 0.05 level of significance (.001<0.05).  Based on the data presented, it was evident that the use of PhET interactive simulations is an effective tool in improving the academic performance of the student. It is an effective intervention or remediation tool in assisting learners to develop mastery skills in balancing equations.   This implies that PhET interactive simulation is an effective tool in improving the mastery level of students in balancing chemical equations, thus increasing academic performance.
