Abstract

This research is motivated by the many mistakes made by students in working on questions on matrix material. The aim of the study was to find out how the description of the mistakes made by students of class XI IPS 2 SMA Negeri 2 Gunung Talang. The research method used is descriptive with a quantitative approach. The subjects of this study were students of class XI IPS 2 SMA Negeri 2 Gunung Talang. The sampling technique used purposive sampling technique. Research instruments were used to collect data in the form of tests, interviews and documentation. The test results were analyzed according to Newman's error criteria The results showed that in the indicator of scalar multiplication with matrix, the errors found in (1) subjects with high ability were transformation errors, writing the final answers, (2) subjects with moderate abilities were errors in process skills and errors in writing the final answers, and ( 3) subjects with low ability are understanding errors, transformation errors and errors in writing the final answer. Whereas in the matrix multiplication indicator, the errors found in (1) subjects with high ability were transformation errors, errors in writing the final answer, (2) subjects with medium ability were reading errors, comprehension errors, transformation errors, process skill errors and final answer writing errors, and (3) subjects with low ability are reading errors, understanding errors, transformation errors, and final answer writing errors

Abstract

The background of this research is that srudents’ mathematics learning outcomes are still low, students participate less and have not maximized their role in group learning. The purpose of the study was to determine  the improvement of students’ mathematics learning outcomes by applying the pair checks type cooperative learning model to the VIII grade students of SMP Pertiwi 2. This type of researchis pre-experimental design research with research design one shoot case study. The population in this study were students class VIII SMP Pertiwi 2 Padang which consists of 2 classes retrieval technique. The sample was taken using purposive sampling, so that class VIII.1 was chosen SMP Pertiwi 2 Padang as a sample. The research instrument is the final test in the form of essays and reliability of questions  = 0,86 with reliable criteria. Based on the calculation results, it was obtained that the percentage of learning outcomes obtained by students while using the pair checks type of cooperative learning model obtained t count = -2,5 = 2,5 (absolute value) and t table = 1,79 with the degree of truth (dk) = n-1, n = 12 then (dk) = 11 and a significant rate of 5% = 0,05. So  is rejected because t count > t table. So it can be concluded that there is an increase in student learning outcomes by applying the pair checks cooperative learning model to class VIII students SMP Pertiwi 2 Padang.
