Abstract

This study aims to analyze the profile of students critical thinking skills that emerged during the NOS-based science learning process on the concept of pressure by using a collaborative learning design of sharing and jumping tasks. The NOS-based science learning carried out includes 7 aspects, namely Empirical based, Tentative, Theories and law, Sociocultural embeddedness, Creativity, Scientific method, and Subjective. Indicators of critical thinking skills used are based on Ennis (1985). The method used in this research is descriptive qualitative. This research was conducted in one of the junior high schools in Sumedang Regency, West Java. The research subjects consisted of 16 students from class VIII. Lesson design sharing & jumping tasks consist of learning stages: opening activities, sharing tasks, jumping tasks, and closing activities. The instruments used are observation and audio video recordings during the learning process. The collected data were analyzed using Transcript Based Lesson Analysis (TBLA). The results of the analysis show that the implementation of NOS-based science learning on the concept of pressure by using a collaborative learning design of sharing and jumping tasks can bring up students^ critical thinking skills in the learning process. The activity profile of students^ critical thinking skills that appeared based on the Ennis (1985) indicator in the opening activity found 2 indicators with the percentage of students showing the highest critical thinking activity 41.7%, in the sharing task 1 activity found 5 indicators with the percentage of students showing critical thinking activities the highest was 43.7%, in the sharing task 2 activities found 12 indicators with the percentage of students showing the highest critical thinking activity 83.3%, in the jumping task and closing activities found 8 indicators with the percentage of students showing the highest critical thinking activity 100%.

Keywords: lesson design, critical thinking skills, NOS, sharing & jumping tasks, pressure.
