PhET Interactive Simulation on Gas Properties and its Effect on the Mastery Level on KMT of Selected Grade 10 Students at Emiliano Tria Tirona Memorial National High School

Abstract

INTRODUCTION

The primary purpose of this research is to determine the effect of utilizing a virtual lab simulation develop by PhET on the mastery level of students on the Kinetic Molecular Theory (KMT)

METHODS

The respondents of the study were selected Grade 10 students of Emiliano Tria Tirona Memorial National High School for the school year 2015-2016. The study made use of a validated test on KMT following pretest-posttest quasi-experimental design.

RESULTS

T-test of independent means at 0.05 level of significance revealed that there is a significant difference between the mean score of students who utilized the PhET Simulation and those students who made use of the prescribed activities in the learner's manual. Moreover, student-respondents find the PhET Simulation highly effective in terms of gaining mastery of the subject matter, enhancing the mastery of a competency-based skill, and enhancing their interest in chemistry.

DISCUSSIONS

Since the mean score of the of students who utilized the PhET Simulation is higher than the other group, it was concluded that using PhET Simulation on Gas Properties is an effective tool in increasing students' mastery on KMT.
