Abstract

This study aims to determine the quality of the Biology instrument items on the digestive system material with the Rasch model for analyzing critical thinking skills. The research employed a quantitative descriptive method involving 63 students of senior high schools in Yogyakarta. The data were collected using a critical thinking skills description test and processed using the Rasch model with the Winstep 5.0.3.4 program. The study shows that the overall validity is acceptable. The item validity did not require improvement in items 14, 3, 8, 13, 12, 1, 4, 10, 6, 2, 7, 11, 15, and 9, and required improvement or replaced of item 5 because it did not fit. The analysis result using Cronbach's alpha shows that the overall reliability is very good, and the item reliability is good. Rating scale analysis using partial credit ratings and probability curves shows that respondents need help understanding the five-point Likert scale. The analysis of the item difficulty based on Logit and Wright maps shows that the most difficult item to work on is item 14. Items with moderate categories are items 13, 12, 1, 4, 10, 6, 2, 5, and 7. Items easy to work on are items 11, 15, and 9. The bias results show item 14 gender-biased. The results of the interaction between the item and the person through the ICC plot image show that all items are on the curve of the outfit confidence space and follow the Rasch modeling.

Abstract

STEM-based Engineering Design Process learning model as a learning innovation to improve creative and critical thinking skills. This research aims to determine the influence of the STEM-based Engineering Design Process learning model on creative and critical thinking skills in a multivariate manner, as well as the correlation between students' creative and critical thinking skills on the subject of environmental pollution. The design of this research is Quasi Experimental with a pretest-posttest control group design. The treatment given to the experimental class was learning using the STEM-based Engineering Design Process model, while the control class used the Discovery Learning model with a scientific approach. The results of this research show that there is an influence of the STEM-based Engineering Design Process model on the ability to think creatively and critically in a multivariate manner with a value of sig. in Hotelling's trace from the MANOVA test 0.000 ‹ 0.05, and there is a correlation between creative and critical thinking abilities and the sig value. from the pearson test ‹ 0.000 ‹ 0.05. In conclusion, the STEM-based Engineering Design Process model is able to improve creative and critical thinking abilities, and there is a correlation between creative and critical thinking abilities.
