Abstract

The type of research used in this research is qualitative research. The subjects in this study were students in class VIII A and VIII I of SMP Negeri 9 Surakarta, which consisted of six students. The sampling technique in this study used a purposive sampling technique. The instruments used in this research are interview sheets and test instruments. Qualitative data analysis techniques in this study used the Miles and Huberman method which included data collection, data reduction, data presentation, and drawing conclusions. The results of this study are that the level of critical thinking that can be achieved by research subjects with low mathematical abilities is critical thinking level 1 with characteristics of low mathematical ability in solving mathematical problems on the circumference and area of a circle. Furthermore, the level of critical thinking that can be achieved by research subjects with moderate mathematical abilities is critical thinking level 2. The level of critical thinking that can be achieved by research subjects with high mathematical abilities is critical thinking level 3.

Abstract

Research Objective: To improve students' learning outcomes in social studies. By implementing the Problem Based Learning (PBL) method to help students understand social studies concepts better. Methodology: This research is a Classroom Action Research (CAR) consisting of four stages of activities, namely: (1) planning stage, (2) action implementation stage, (3) observation stage, and (4) evaluation stage and reflection. The research sample was fifth grade students at SDN 143 Tamiai, with research instruments namely observation, documentation and tests. Main Findings: The results of the study showed that in the pre-cycle, students' learning completeness reached 27.58%. There was an increase of 20.69% in the implementation of cycle I. In cycle II, there was an increase of 37.93% or learning completeness of 86.20%. Thus, it is proven that the use of the Problem Based Learning learning model can improve students' learning outcomes. Research Update: This research strengthens the relationship between the Problem Based Learning model and learning outcomes, especially in social studies lessons.
