The Influence of the DOCAR Model on the Critical Thinking of Junior High School Students

The DOCAR learning model is a development model to improve the critical thinking skills of first-school students. Where this DOCAR learning model is a contextual problem-based model that is able to improve students' critical thinking skills. The subjects of this study were junior high school students in the even semester of the 2020/2021 academic year. Data collection techniques are carried out by observation and critical thinking skills tests. The technique of estimating data in this study is (1) instrument validity analysis. To see the validity, reliability of the instrument and analyzed using the interrater correlation coefficient and Cronbach alpha (Webb), (2) data analysis of learning implementation. To see the percentage of DOCAR model implementation, (3) analyze student activity. To see student activity, (4) analyze critical thinking skills. To see the influence on learning outcomes between the experimental class and the control class, it was analyzed by a t-test for two independent samples (independent sample t-test). This analysis is carried out by comparing the significance values. From the results of the study, it was concluded that there is an influence of the DOCAR learning model on critical thinking ability.
