This study aimed to examine the psychometric properties (reliability and validity) of the Arabic version of Sherouk's Critical Thinking Test. This test has four parts, each of which provides a story that is divided into an introduction and a scene; each story is then followed by a list of sensitive questions featuring two response options (Agree/Disagree). A sample of 158 university students participated in this study. The results showed that the reliability of the entire scale was 0.885, and the reliability of each of its four parts was 0.885, 0.829, 0.772, and 0.721, respectively. Confirmatory factor analysis of the collected data revealed a good fit with the latent constructs (CMIN/DF: 1.446; CMIN/DF: 1.357; CMIN/DF: 1.417; and CMIN/DF: 1.151) for parts one to four, respectively. The test's adaptability was considered when designing this instrument, and examinees were invited to review it. This paper recommended using this instrument in the fields of performance, leadership, selection, training, and improvement, and it was also created as a tool to measure individuals' critical thinking skills and abilities in organizations, companies, and academic environments. The English and German versions of this test were also examined; these versions are now currently available for use.

Proporsi siswa yang memiliki kemampuan berpikir kritis dan kepercayaan diri pada kategori minimal “baik” lebih dari 75%. Dengan demikian dapat disimpulkan bahwa pembelajaran berbasis proyek efektif ditinjau dari prestasi belajar, kemampuan berpikir kritis, dan kepercayaan diri siswa. The effectiveness of project-based learning viewed from students’ learning achievement, critical thinking skill, and self-confidenceAbstractThe purpose of this study was to describe the effectiveness of project-based learning in statistical material viewed from learning achievement, critical thinking skills, and self-confidence of seventh-grade junior high school students. Project-based learning consists of six steps: (1) determining the project; (2) designing project completion steps; (3) preparing the project implementation schedule; (4) completion of the project with facilitation and monitoring from the teacher; (5) preparation of reports and presentation/ publication of project results; and (6) evaluation and results of the project. The population in this study was seventh-grade students of SMP 1 Yogyakarta, Indonesia. The instruments used were a learning achievement test, a critical thinking ability test, a self-confidence questionnaire, and an observation sheet of learning accomplishments. Hypothesis testing uses the proportion Z test at a significant level of 95% (α = 5%). Based on the results of the hypothesis test, the proportion of students who have learning achievement reached KKM was more than 75%. The proportion of students who have critical thinking skills and self-confidence in the minimum category of "good" was more than 75%. Thus it could be concluded that project-based learning was an effective view from students’ learning achievement, critical thinking skills, and self-confidence.

The Rasch Model

This study aims to determine the effect of applying problem-based learning models on critical thinking skills and scientific attitudes of pre-service chemistry teachers in Basic Chemistry 1. This quasi-experimental research uses pre-test and post-test through an unequal control group design. This research has been carried out for 3 months from September-November in 2021 on pre-service chemistry teachers. The data were analyzed using Hotelling's T2 test and the Rasch model. Empirical evidence shows that based on Hotelling's T2 test results obtained a significance value of 0.001 < (0.05) with a partial eta squared value of 0.28 which means Ha is accepted. So, it can be concluded that there is a contribution of problem-based learning models on critical thinking skills and scientific attitudes of students with the contribution of 28%. Another finding also shows that based on the results of the Rasch model test, it shows that in the experimental class the indicators of critical thinking skills and scientific attitudes are mostly possessed the ability to synthesize attitudes towards scientific investigations. The indicators of critical thinking skills and scientific attitudes are least possessed the ability to analyze and chemistry learning experiences. The conclusions of this study include there is a significant effect of the application of the PBL model on students' critical thinking skills and scientific attitudes with a model contribution of 28%, as well as critical thinking skills and scientific attitudes that most students have in the experimental class are analytical skills and attitudes towards scientific investigations.

The present research assessed the structural validity of The Ross Test of Higher Cognitive Processes, a recently developed instrument designed to assess the higher-level thinking skills of analysis, synthesis and evaluation as outlined in Bloom's Taxonomy. Confirmatory factor analysis, analysis of variance and trend analysis were used to test the correspondence between Bloom's Taxonomy and the Ross Test, and to study the developmental nature of critical thinking. Subjects were 154 gifted third through sixth graders. Confirmatory factor analysis of individual test items and of the eight Ross subtests provided empirical evidence for the structural validity of this instrument, and normative data on gifted students' performance on the test was presented. This investigation of the Ross Test yielded findings relevant to the use and interpretation of this measure of critical thinking in the gifted and regular classroom.
