Abstract

The critical thinking skills need to be possessed by every student, and its evaluation requires the right measuring tool., while the critical thinking assessment has not used the right instrument. This study aims to produce an instrument to measure critical thinking skills in a circular motion. The method using Research and Development assimilated from Gall, Gall, & Borg and Sugiyono, adjusting to the purpose and time, so the steps are 5. The R&D steps are research and information collection, planning, developing a preliminary form of product, limited field test, and product revision. The developed instrument consists of 10 conceptual essay questions. The result from expert validation of construction, substance, and language aspects is very valid in each aspect, with 86.1%, 81.7%, and 75%. The result from field testing in 32 students is tested with Anates software and has a reliability of 0.77 in a high category. The validity result gets eight valid questions. Those eight valid questions have discrimination power which is medium, good, and very good. The difficulty levels are medium and hard. The average value of the student's score on the instrument is 43.69 shows that the students have medium skills of critical thinking in a circular motion. This study implies that the final product of the instrument consists of eight conceptual essay questions in the google form.

Abstract

This study aims to measure students' complex problem solving on the concept of global warming. This study used a quasi-experimental design with nonequivalent control group design. The research subjects were 52 grade 11 high school students in Pesawaran District using a purposive sampling technique. This study uses eight essay questions as complex problem-solving instruments with six skill indicators, namely 1) articulating the problem, 2) identifying the desired result, 3) brainstorming creative options, 4) analyzing and choosing the best option, 5) developing an action plan that will achieve the result desired end 6) establish a plan of action and adapt as needed. The results showed that there was an effect of learning using the nature of science on students' complex problem solving with an increase of 0.75 in the high category in the experimental class compared to the control class with an increase of 0.35 in the medium category.
