Abstract

This study examined the effectiveness of QR-code materials in teaching the Circulatory System to Grade 6 students at San Agustin Elementary School. The rapid shift in educational technology has significantly changed the way science instruction is delivered. From relying mainly on textbooks, classrooms are moving toward interactive and multimedia approaches that encourage engagement, active participation, and deeper understanding. Grounded in Mayer’s Cognitive Theory of Multimedia Learning and supported by the Enhanced Basic Education Act of 2013 (RA 10533), which highlights the importance of digital literacy and 21st-century competencies, this research explored how QR-code-based resources contribute to conceptual learning and student involvement in science. The study employed a quantitative quasi-experimental design involving two Grade 6 sections with a total of 79 respondents. Data-gathering tools included a pretest and posttest to measure academic performance and a survey questionnaire to evaluate students’ perceptions in terms of engagement, interaction, knowledge retention, and critical thinking. Most respondents were aged 11 years or younger (76%), and 52% were female. Cellphones were the most commonly owned devices for accessing QR-code materials (70%). Pretest scores indicated basic knowledge of the circulatory system, while posttest scores were reported as significantly higher. The p-value was presented as .000, which should be reported using an inequality rather than as zero. Students rated the materials as effective for interaction, retention, and application of concepts. Reported limitations included unstable internet connectivity, technical problems, and possible overreliance on digital tools. The reported pretest–posttest improvement and student evaluations suggest that QR-code materials can supplement instruction on the circulatory system when combined with teacher guidance.
