The study was to describe the implementation of Problem-Based Learning (PBL) toward the improvement of students’ Higher Order Thinking Skill (HOTS) and characters and to describe the obstacles that had been encountered within the implementation. The study was a mixed research that made use of concurrent mixed method design. The population in the study was the students from eight junior high schools that had been selected from six provinces in Indonesia namely the Yogyakarta Special Region, Bengkulu, South Borneo, West Nusa Tenggara, Southeast Sulawesi and Papua. There were 648 students who had been selected randomly from these schools. The researchers conducted the PBL process within the experimental classes and the expository learning process within the eight control classes. The data gathering process was conducted through the test, the self-assessment and the open questionnaire. The quantitative data analysis was conducted inferentially using multivariate and univariate analysis, while the qualitative data analysis was conducted descriptively. The results of the study showed that: (1) the implementation of PBL had been more effective in comparison to the expository one in terms improving the students’ HOTS; (2) the implementation of PBL had not been more effective in comparison to the expository one in terms of improving the students’ characters; and (3) in overall the obstacles that had been encountered within the implementation of PBL process were related to the teachers’ unpreparedness, the time allocation, the unequal students’ input, the students’ learning habits and the difficult assessment.

This research aims at knowing the factors, involving both students and school levels, related to the math learning achievement for students in Indonesia, Japan, and Algeria by using PISA 2015 data. The sample in this study consists of students from three countries that took part in PISA 2015. The three countries chosen are Indonesia, Japan, and Algeria, each respectively having as participants 5.800, 6.411, and 4.460. the findings showed that the sense of belonging of students towards mathematics, the socio-economic status of their families, and the average of school’s social-economic status can predict significantly the students’ math learning achievement for the Indonesia and Japan, while for the Algerian students the socio-economic status is statistically insignificant in predicting their math learning achievement. The outcome of this analysis support the idea that the school attended plays a big role as far as mathematics learning achievement is concerned. To conclude, it should be summed up that the affective characteristics (sense of belonging of students), family background (students’ socio-economic status), and the variable school-level (average socio-economic status of schools) can be among students as far as mathematics learning achievement is concerned.

Jenis penelitian adalah penelitian kualitatif eksploratif. Subjek penelitian adalah mahasiswa tahun pertama Jurusan Pendidikan Matematika Universitas Nusa Cendana yang terdiri dari tiga subjek (kemampuan tinggi, sedang dan rendah). Instrumen utama dalam penelitian ini adalah peneliti sendiri dan dibantu dengan soal tes pemecahan masalah konteks budaya serta pedoman wawancara. Data penelitian dianalisis secara kualitatif berdasarkan indikator kemampuan pemecahan masalah serta divalidasi menggunakan triangulasi waktu. Hasil penelitian menunjukkan subjek berkemampuan rendah memiliki kemampuan pemecahan masalah dalam kategori cukup. Subjek memiliki keterbatasan dalam pemahaman dan penggunaan aturan matematika dalam pemecahan masalah konteks budaya. Subjek berkemampuan sedang cenderung memiliki ketegori kemampuan pemecahan masalah bergantung pada konteks masalah. Subjek masih belum konsisten terkait kemampuannya dalam pemecahan masalah matematika. Subjek berkemampuan tinggi memiliki kemampuan pemecahan masalah dalam kategori baik. Subjek memiliki performa matematika yang baik yang ditandai dengan pemahaman masalah yang baik, perencanaan, implementasi dan solusi yang akurat sesuai konteks masalah. AbstractThe purpose of this research is to describe the ability of mathematical problem solving of First-Year University students in solving geometry problems of cultural context. This research is qualitative-explorative. The subjects are from the First-Year University student of Mathematics Education Department at Nusa Cendana University who consists of three subjects (high, medium, and low ability). The main instrument in this research is researcher himself and equipped by instruments of problem-solving question and interview guides. Data were analyzed qualitatively based on indicators of problem-solving abilities and validated using time triangulation. The results showed the low ability subject had the problem-solving ability in the medium category. Subjects had limited in understanding and use of the rules of mathematics in solving cultural context problems. The medium ability subject had problem-solving ability depend on the context of the problem. The subject still not consistently related to its ability in solving mathematical problems. The high ability subject had the problem-solving ability in the good category. The subject had good mathematics performance that is characterized by a good understanding of the problem, planning, implementation and accurate solutions to context problems.
