Improving the experimentation skills in science of grade 5 learners through electronic inquiry-based learning kit

This action research investigates the effectiveness of the Electronic Inquiry-Based Learning Kit (EIBLK) in enhancing the experimental skills of Grade 5 pupils in Science, specifically focusing on the learning competency: discuss why some materials are good conductors of heat and electricity.The study responds to the observed challenges in Parioc East Elementary School, where students exhibited low science performance due to passive learning approaches.Grounded in the 7E instructional model and constructivist learning theory, the EIBLK was developed to promote active, inquiry-driven learning through digital and hands-on experiments.A one-group pretest-posttest design was employed involving 18 Grade 5 learners.Results revealed a significant increase in mean scores from 4.94 (low) in the pretest to 12.67 (very high) in the posttest.A paired-sample t-test indicated a statistically significant improvement (t = 13.21,p < 0.05), while Cohen's d = 4.29 showed a very large effect size.Additionally, 100% of the respondents demonstrated improved experimental skills after the intervention, compared to only 31.23% in the pretest.These findings align with global and local literature supporting the use of inquiry-based and technology-enhanced instruction in science education.The study recommends integrating EIBLKs into regular instruction to develop learners' scientific process skills and foster 21st-century competencies.It further proposes the replication of the intervention across schools to improve science outcomes and promote active learning.
