| What statistical finding was observed between the experimental and control groups? | there was a significant difference between the control and experimental groups. | The research employed a two-fold approach, consisting of an experimental group and a control group. An assessment tool comprising opinion-based questions and achievement-based tests (questionnaire) was employed. The study commenced with a pre-test for the control group, followed by a post-test after delivering suitable teaching-learning experiences to the experimental group. Based on statistical data, there was a significant difference between the control and experimental groups. It concludes that the conventional lecture-based approach in teaching science concepts proved inadequate in achieving desired learning outcomes. | 405 | relationship | 0.970 | https://ejournals.ncert.gov.in/index.php/ET/article/view/5111 | Based on statistical data, there was a significant difference between the control and experimental groups.

| What is the purpose of PhET Interactive Simulations? | to facilitate improved comprehension and learning of various scientific and mathematical concepts for both students and educators | Published 2026-04-15 Simulations represent computational replicas of actual or hypothesized scenarios or natural occurrences. These virtual models enable users to investigate the consequences of altering parameters within them. PhET Interactive Simulations, often referred to as "PhET," constitute a series of free online interactive simulations developed by the University of Colorado Boulder. These simulations are purposefully crafted to facilitate improved comprehension and learning of various scientific and mathematical concepts for both students and educators. This study endeavours to evaluate the current grasp of science concepts among eighth-grade students and aims to enhance these concepts through the utilization of PhET simulations. Five pivotal science concepts were selected from the eighth-grade science textbook in Tamilnadu as the focus of this study. | 438 | summary | 0.970 | https://ejournals.ncert.gov.in/index.php/ET/article/view/5111 | These simulations are purposefully crafted to facilitate improved comprehension and learning of various scientific and mathematical concepts for both students and educators. | ||||
