This study aims to produce teaching materials in the form of student worksheet based on problem-based learning (PBL) in respiratory system material to improve quantitative literacy of eleventh grade students of senior high school using ADDIE development model method (Analysis-Design-Development-Implement-Evaluation). The instruments of this study were validation sheets for the teaching materials and pretest and posttest for quantitative literacy. The validation sheets were validated by an expert at teaching material, an expert at material, two biology teachers, four colleagues and fifteen students. Pretest and posttest to measure students' quantitative literacy were validated by two experts and were tested to 29 eleventh grade students of senior high school. The results revealed that the teaching materials were theoretically feasible to use in that the feasibility score of the materials was 3.50 (very good), the feasibility score of the teaching materials was 3.59 (very good), and the feasibility score of the biology teachers and colleagues was 3.52 (very good) and the students' response score was 3.48 (very good). Moreover, the results of quantitative literacy showed that there are nine students categorized to high criteria and twenty students categorized to moderate criteria. The results indicated that the PBL-based student worksheet as a teaching material is feasible and recommended to be implemented in the learning process. © Published under licence by IOP Publishing Ltd.
