Abstract

This study aims to examine the effectiveness of implementing Qreatif Educative Virtual Lab in improving middle school students' conceptual understanding of temperature and heat. This study uses a quasi-experimental approach with a single-group pretest-posttest design. The research subjects consisted of 18 students from class VII A at a junior high school in Kemiri District, Purworejo Regency, in the 2025/2026 academic year. The research instrument was a 10-item multiple-choice test administered before and after the treatment. The data were analyzed using the N-Gain test to assess the increase in conceptual understanding and the paired t-test to test the difference in learning outcomes. The average student score increased from 43.8 to 65.5 with an N-Gain value of 0.376, which falls into the moderate category. The paired t-test showed a significant difference (p < 0.05). Thus, the use of the Qreatif Educative Virtual Lab proved to be effective in improving students' conceptual understanding, although further optimization in the learning process is still needed.
