Analysis Of Students' Critical Thinking Skills On The Material Of Flat Shapes In The Fifth Grade Of Tindoi State Elementary School

The ability to think critically is one of the abilities that must be mastered by students and has an important role in the mathematics learning process. Based on initial observations, it shows that the critical thinking skills of fifth graders at SD Negeri Tindoi are still low. This study aims to analyze students' critical thinking skills on the flat-shaped material. This research is a qualitative research. This study uses 4 indicators of critical thinking skills according to Robert Ennis, namely providing simple explanations, making further explanations, determining strategies and tactics, and concluding. The subjects in this study were 9 students of class V SD Negeri Tindoi, consisting of 3 male students and 6 female students. Data collection was carried out by written tests, interviews, and document studies. Data analysis techniques used are data reduction, data presentation, and drawing conclusions. The technique of checking the validity of the data is using the triangulation technique. Based on the results of the study, it was shown that the critical thinking skills of the fifth grade students of SD Negeri Tindoi belonged to the low category. This can be seen by the number of students who have low critical thinking skills as many as 4 students, 2 students with sufficient critical thinking skills, and 3 students with very low critical thinking skills out of 9 students. The students' critical thinking ability on each indicator in solving the problem of flat shape material shows different results in each category of critical thinking ability, namely: 1) Students with sufficient critical thinking ability have been able to meet three indicators of critical thinking ability, namely the indicator provides an explanation. simple, determine strategies and tactics and conclude. 2) Students with sufficient critical thinking skills have been able to meet two indicators of critical thinking skills, namely indicators of providing simple explanations, determining strategies and tactics, and 3) Students with very low critical thinking skills are only able to meet one indicator of critical thinking skills, namely indicators provide a simple explanation.
