<![CDATA[Low physics achievement among junior high school students, particularly on the topics of work and energy, indicates the need for more effective instructional strategies. This study examined the effect of a guided inquiry approach assisted by PhET simulations on students’ learning outcomes in Work and Energy. A nonequivalent control group design was employed, involving 30 students in the experimental class and 30 students in the control class. The instrument consisted of 20 multiple-choice items designed to assess students’ understanding of fundamental concepts in Work and Energy. The results showed that the implementation of the PhET-assisted guided inquiry approach significantly improved students’ learning outcomes. This conclusion was supported by the results of an independent t-test and a high effect size. Nevertheless, the study was limited to a single topic and relied solely on quantitative data. Future research is therefore recommended to investigate other physics topics and to incorporate qualitative.]]>
