The Measurement of Preparing Recycling Materials with Many-Faceted Rasch Model


Ahmet Volkan YÜZÜAK


ABSTRACT
The research contributes to raising environmental awareness, particularly of recycling among 5th-grade students, by designing re-cycled materials. One question is: How can recycling materials be evaluated objectively by science teachers? Many-Faceted Rasch Model, based on Item Response Theory, can be an answer. This model is used to assess the performance judged. It also analyzes jury bias and specifies the most uncomplicated and complicated criteria, which will provide opportunities to improve students’ skills. The study was conducted in 2021-2022 academic year spring semester. Model’s surface are 14 projects, 10 criteria, and 11 jury: science teachers. FACETS program was used to analyze data. Findings of the study revealed that recycling project coded as RP 8 is more successful, student-level compatibility criterium was the simplest, and creativity was the hardest. the jury coded as ST8 is the most lenient, and the jury coded as ST7 is the severest.
