The present study explores the factorial structure and the degree of measurement invariance of 12 divergent thinking tests. In a large sample of German students (N = 1328), a three-factor model representing verbal, figural, and numerical divergent thinking was supported. Multigroup confirmatory factor analyses revealed that partial strong measurement invariance was tenable across gender and age groups as well as school forms. Latent mean comparisons resulted in significantly higher divergent thinking skills for females and students in schools with higher mean IQ. Older students exhibited higher latent means on the verbal and figural factor, but not on the numerical factor. These results suggest that a domain-specific model of divergent thinking may be assumed, although further research is needed to elucidate the sources that negatively affect measurement invariance.

ABSTRACTThis research is aimed to know the differences increase critical thinking skills through learning group and individual problem solving in thermochemical material. This research uses a quasi-experimental design with nonequivalent control group design and study sample consisted of 103 students, divided into the first experimental (group problem solving) (35 students), the two group experimental (individual problem solving) (34 students). The collected through pretest-posttest. The analyzed with the Kruskal Wallis test, the results showed that the learning problem solving as a group or individually can improve students’ critical thinking skills. Statistical test there are significant differences in the students critical thinking skills thermochemical material between students who received group and individual problem solving. Critical thinking skills improvement with problem solving individual learning higher compared with group learning problem solving.Keywords: problem solving learning, critical thinking skillsABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan peningkatan keterampilan berpikir kritis siswa melalui pembelajaran group dan individual problem solving pada materi termokimia.

This research is motivated by the competence of teachers in preparing poor learning outcomes tests and has not been able to measure high-level thinking skills, especially critical thinking skills. Therefore the researcher seeks to improve teacher competence in compiling tests on student learning outcomes based on critical thinking skills through academic supervision. This study uses a school action research design that has stages of planning, implementation, observation, and reflection. This research was conducted for 2 months starting April 9 to May 17, 2019 for Physics teachers in the 7 target schools. Data is sourced from interviews with teachers and test documents prepared by the teacher. Data collection techniques include observation, interviews and documentation. Data analysis through the stages of data collection, data simplification, data presentation, conclusion drawing. Data were analyzed using assessment rubrics adjusted to indicators of critical thinking skills. The results of this study conclude that teacher competence in preparing tests of learning outcomes based on critical thinking skills has increased from the first cycle with a percentage of 61% with sufficient categories to 76% with good categories in cycle II.

The background of the research is the low assessment of high order thinking skills of students due to the conventional methods used by the school. The aims of this study are: (1) how student learning activities when using hybrid learning Student Teams Achievement Division (STAD) and jigsaw, (2) how student learning activities when taught using the direct learning model, and (3) the effect of hybrid learning Student Teams Achievement Division (STAD) and jigsaw towards high order thinking skills. This study used a quasi experimental nonequivalent control group design with the sample of 50 students from a population of vocational high school students in Ponorogo. Data collection techniques used instruments in the form of high order tests and non-test instruments in the form of observation sheets. Data analysis used was independent sample t-test. The results showed: (1) the use of Student Teams Achievement Division (STAD) based on hybrid learning and jigsaw made 28% of students were very active, 28% of students active, and 44% of students quite active in the learning process, this was evidenced by an average value of 70.56, (2) the use of direct learning models in learning made 24% of students quite active, 36% of students less active, and 40% of students passive in the learning process, which can be seen from the acquisition of an average value of 51.52, and (3) there was a significant effect of Student Learning Achievement Division (STAD) based on hybrid learning and jigsaw on students' high order thinking skills.
