Approaches to Respiratory and Excretion Systems Teaching: An Innovative Learning through Cirsa

The purpose of this study was to analyze the effect of the cooperative integrated reading and composition learning model based scientific approach (Cirsa) and conventional learning on eighth-grade students on the subject matter of human excretory and respiratory system. Cirsa is based on constructivism learning theory that integrates the CIRC learning model with a scientific approach. The research method used was quasi-experiment using pretest-posttest non-equivalent control group design. Participants (N = 160 students; M = 95, F = 65) were randomly selected from junior high school. One group was assigned to Cirsa learning (n = 80), and another group was assigned to conventional learning (n = 80). The conceptual of excretory and respiratory system of the human using tests with open questions were developed and used. The results showed that the Cirsa learning model was more effective than conventional learning in the subject matter of the human excretory system and the respiratory system. Based on the findings, the teachers are advised to develop the biological concept of students by using Cirsa learning, which emphasizes reading through scientifically based activities.
