Full text linkThis study aimed to determine the effectiveness of problem based learning model in terms of students' mathematical communication skills. The population of this study was all students of grade VIII of SMP Negeri 2 Pugung, Tanggamus in the academic year of 2018/2019 as many as 135 students, which were distributed into five classes. The sample of this study were students in VIIIA and VIIIB class selected by cluster random sampling technique. The design which was used was a pretest-posttest group design. Data analysis used the Mann-Whitney U test and proportion test. The results of data analysis showed that the mathematical communication skills of students who followed the PBL model were higher than the mathematical communication skills of students who followed conventional learning and the proportion of students who had good categorized of mathematical communication skills was more than 60% of the number of students who followed the PBL model. Thus, the PBL model was effective in terms of students' mathematical communication skills. Keywords : comunication skils of mathematics, problem based learnin

IMPLEMENTASI METODE SELF-ASSESMENT UNTUK MENINGKATKAN HASIL BELAJAR MATEMATIKA SISWA KELAS XI IPA SMA NEGERI I BANYUMAS PADA MASA PANDEMI COVID-19
No full textThe purpose of this study is to determine an increasement in student learning outcomes in mathematics learning using the Self-Assessment method in class XI MIPA 2 students, totaling 36 students in Linear Program material at SMA Negeri I Banyumas. This research is a Classroom Action Research (CAR) which consists of four steps in the cycle, namely Planning, Action, Observing, and Reflecting. Data collection and analysis techniques were analyzed using descriptive statistics. The test result obtained in the first cycle obtained a class average of 67.05 and a percentage of completeness of 50%. From the Self-Assessment sheet, it is known that students' difficulties are determining the area of completion and modeling the problem into a linear program, so it is necessary to do cycle II to improve student learning outcomes. From the test results in cycle II, it was found that the class average increased to 75.56. Students' learning completeness increased from previously only 50% of students who completed to 70%. The findings of student difficulties written on the Self-Assessment sheet are still dominated by modeling the problem and its objective function. The conclusion from this research is that the implementation of the Self-Assessment method shows an increase in student learning outcomes.Keywords: classroom action research; learning outcomes; self-assessment DOI: http://dx.doi.org/10.23960/mtk/v8i2.pp273-288 Alternative Link -> PD
