Abstract

Problem-Based Learning (PBL) and Case-Based Learning (CBL) are two typical learning approaches that involve problem-solving activities, likely to encourage students' mathematical connection abilities. This study aimed to describe the differences in mathematical connection ability between students studying with the PBL and those who used the CBL approach. A quasi-experiment with a pretest-post-test non-equivalent group design was conducted for the purpose. The data collection method was non-routine problems about mathematical connections. The data was analyzed using inferential statistics. Paired sample t-tests adopted were to examine the difference between pretest and post-test data in each experimental class, and independent sample t-tests were to verify the difference in the effectiveness of the two learning approaches. The results showed that the PBL and CBL approach enhanced mathematical connection ability. However, there was no significant difference in the mathematical connection ability between students who studied with the PBL and CBL approaches. The results, furthermore, suggest teachers construct appropriate learning to foster mathematical connection ability.

Abstract

This study aims to present the abilities of junior high school students' mathematical literacy in Sleman Regency, Yogyakarta Special Region Province, Indonesia. This survey used proportional random sampling to sample 428 eighth graders from fourteen schools. A mathematical literacy task for this study has been tested for validity and reliability. The data were analyzed by converting the test scores using interval scales to categorize the abilities. Based on the analysis, the mathematical literacy skills of students were generally included in the low category, with a distribution of 62.15% of students in the very low category, 13.32% in the low category, 14.02% in the medium category, 5.37% in the high category, and 5.14% in the very high category. They were: 1) in a low category for the formula and employ processes, and a very low category for the interpreting process; 2) in a low category for the Quantity and Uncertainty Data content, and a very low category for the change and relationship and space and shape content; and 3) in a low category for the Personal and Occupational context, and a very low category for the social and Scientific context. The results of this study are expected to be a consideration for related parties to improve the quality of education, especially in learning mathematics.

Abstract

Salah satu syarat pengembangan karier guru adalah menulis karya ilmiah. Faktanya syarat ini justru menjadi penghambat bagi guru untuk naik pangkat dikarenakan kurangnya kemampuan dan minat menulis di kalangan guru. Tujuan pengabdian kepada masyarakat ini adalah untuk memberikan pengetahuan dan pemahaman tentang cara menulis dan mempublikasikan artikel ilmiah pada jurnal bereputasi guna menunjang karier guru. Khalayak sasaran kegiatan pengabdian ini yaitu para guru di SMA Negeri 1 Salaman yang sebagiannya mengalami kendala kenaikan pangkat karena kurangnya syarat publikasi artikel ilmiah. Kegiatan pengabdian dilakukan melalui tiga tahapan yaitu perencanaan, pelaksanaan, dan evaluasi. Metode kegiatan pengabdian berupa pelatihan dengan metode ceramah, tanya jawab, dan diskusi. Pelaksanaan kegiatan pengabdian berupa pelatihan ini didukung oleh beberapa faktor yang memberikan banyak kontribusi atas keberhasilan kegiatan. Kegiatan pengabdian ini secara keseluruhan berjalan dengan baik. Hasil kegiatan berupa peningkatan pemahaman guru mengenai cara menulis artikel ilmiah yang baik, cara menentukan jurnal ilmiah yang sesuai, dan tata cara pengiriman artikel pada online journal system. Kegiatan pelatihan juga membangkitkan motivasi guru dalam menulis artikel ilmiah tidak hanya untuk pengembangan karier namun juga pengembangan diri. Capaian ini terlihat dari antusiasme guru saat sesi diskusi dan hasil refleksi di akhir kegiatan bersama guru dan kepala sekolah yang disampaikan secara lisan.
