The effectiveness of Electro Briefcase intervention in improving the test performance in Science V

The research aimed to improve the test performance in science of the Grade V - Einstein pupils of Dadiangas West Elementary School, particularly on the topic of electricity and circuits through the “Electro Briefcase” intervention, emphasizing the use of tangible learning materials and active learning strategies. A mixed method approach was employed. Data were collected through pre-tests, post-tests, and interviews, and analyzed using a t-test and thematic analysis. Results revealed a significant improvement in test scores—from a mean of 7.88 (low performance) to 26.09 (very high performance) post-intervention (p < 0.0001). Qualitative key findings indicate that tangible learning materials and active learning support conceptual understanding of abstract science topics. These results demonstrate that the Electro Briefcase intervention is effective in improving test performance in Science V. It is recommended that science teachers integrate tangible materials like the Electro Briefcase when teaching abstract concepts. Future researchers are encouraged to explore similar interventions across different science topics and grade levels to further validate its impact.
