Measurement of critical thinking in physics: The identification of students' critical thinking skill through the work report on momentum conservation?

This study aims to measure students' critical thinking skills through the ability to make practical work reports. The method used is qualitative descriptive method in the form of critical thinking skills through assessment of student work reports and questionnaire data. Rubric that used to measure students' critical thinking skills with 10 indicators: clarity, accuracy, precision, consistency, relevance, strength, reason, depth, breadth and fairness. The study sample was 34 students. The results showed that students' critical thinking skills through work reports were still 17.6% of students already had very high critical thinking skills, 58.82% had moderate critical thinking skills and as many as 23.53% students have weak critical thinking skills. Students have a high category in the breadth. Then clarity, accuracy, precision, consistency, and relevance have a moderate and evidence has a weak. The results of the student and teacher questionnaires about the application of practicum also stated that before practicum students were still sometimes given time to conduct preliminary studies.
