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

Menulis PTK merupakan suatu pengembangan kompetensi profesional bagi guru untuk melakukan inovasi pembelajaran sekaligus menjadi salah satu persyaratan peningkatan karier guru. Namun, masih banyak guru belum mampu menulis laporan PTK karena keterbatasan pengetahuan serta kurangnya motivasi dalam hal ini. Tujuan program pengabdian masyarakat ini adalah menambah pengetahuan tentang penulisan laporan PTK untuk mendukung kompetensi profesional dan motivasi guru dalam menulis PTK. Sasaran peserta yaitu para guru di SMAN 1 Salaman dan SMPN 2 Muntilan yang berjumlah 72 orang. Kegiatan pengabdian terdiri dari tiga tahap: persiapan, pelaksanaan, dan evaluasi. Sementara metode pelaksanaan yaitu pelatihan yang mencakup sesi ceramah, tanya jawab, dan diskusi. Untuk melihat ketercapaian tujuan kegiatan digunakan angket respons yang mengukur kebermanfaatan kegiatan dalam menambah pengetahuan penulisan laporan PTK, motivasi, dan keterlaksanaan. Analisis dilakukan dengan menghitung persentase peserta yang memberikan respons positif terhadap pernyataan angket. Hasil dari program ini yaitu menambah pengetahuan guru mengenai penulisan laporan PTK yang meliputi perumusan masalah, penyusunan kajian teori, metode penelitian, hasil dan pembahasan hingga kesimpulan. Selain itu, pelatihan ini mampu membangkitkan motivasi para guru untuk menulis PTK, tidak hanya untuk tujuan karier, tetapi juga untuk pengembangan kompetensi profesional.
