Improving Learning Outcomes on the Human Respiratory System through Experiential Learning Assisted by Respiration Kit for Grade VI Elementary Students

This classroom action research aims to improve students’ learning outcomes on the human respiratory system through Experiential Learning aided by a Respiratory Kit. The study involved 23 sixth-grade students at SD Negeri Randuacir 02, Salatiga, and was conducted in two cycles using the Kemmis and McTaggart model. Data were collected through observation sheets, tests, and documentation. Results showed that Experiential Learning aided by the Respiratory Kit gradually improved student learning outcomes. In the pre-cycle, only 17.39% of students achieved the minimum competency standard of 70. This increased to 65.22% in Cycle I and reached 86.96% in Cycle II. Teacher engagement also increased from 78.57% in the first session of Cycle I to 96.43% in the second session of Cycle II. These findings indicate that Experiential Learning supported by the Respiration Kit effectively improves learning outcomes, teacher engagement, and student engagement. This model is recommended for elementary school teachers and curriculum developers as an alternative for teaching abstract science concepts by providing concrete materials that students manipulate in groups, guiding them through each stage of Kolb’s cycle using structured worksheets, and allocating time proportionally to each stage. Further research is recommended to measure long-term retention and involve broader participants.
