Abstract

In this research, the authors investigated difference in the mathematical problem-solving abilities of students at SMKN 1 Grati Pasuruan, in terms of the cognitive style of adaptation and innovation of class XI. Data collection was carried out by giving an Adaptation-Innovation in Workplace s (AI-W) questionnaire to determine students' cognitive styles and the Matrix Problem Solving Task (TPMM) to measure the mathematical problem solving abilities. Data collection is used to obtain relevant and accurate data. The methods used for data analysis techniques are questionnaires, tests, and interviews. In this study, students with an adaptive cognitive style were able to fulfill three of five indicators of solving mathematical problems, while subjects with an innovative cognitive style were able to fulfill four of them. The results of this research indicated that students in the innovation group performed better than the adaptation group. Overall, these results provide a more detail description of individual differences in the math problem-solving abilities of SMK students on the matrix.

Abstract

Difficulty understanding the concept of fractions is still a major challenge for elementary school students and has an impact on numeracy skills and self-efficacy in learning mathematics. This study aims to analyze the learning difficulties of grade IV students of SD Muhammadiyah 1 Taman on fractional material reviewed from numeracy ability and self-efficacy. The research method used a quantitative descriptive approach involving 25 students of grade IV A. Data were collected through numeracy ability tests, Bandura scale-based self-efficacy questionnaires, and structured interviews. The results showed that students' numeracy ability was in the medium category with an average achievement of 56.8%, with dominant difficulties in the aspects of fraction comparison (42%) and mixed fraction counting operations (38%). Student self-efficacy was also moderately (62.7%), with the magnitude dimension obtaining the lowest score (56%). The Pearson correlation test showed a strong positive relationship between numeracy ability and self-efficacy (r = 0.724; p < 0.01), while regression analysis showed a 52.4% contribution to numeracy ability to self-efficacy. The results of the interviews confirmed that students better understand the concept of fractions through concrete media and contextual learning. This study recommends the application of ethnomathematics-based fractional learning model with a strategy of increasing self-efficacy through positive reinforcement and scaffolding.

Abstract

Pembelajaran matematika bertujuan mengembangkan kemampuan komunikasi matematis siswa. Namun, hanya 7% siswa SMP yang mempunyai kemampuan komunikasi matematis tinggi. Kemampuan komunikasi matematis, baik tulis maupun lisan, dipengaruhi oleh gaya kognitif reflektif dan impulsif. Oleh karena itu, siswa diupayakan mampu melakukan pengembangan kemampuan komunikasi matematis melalui penyelesaian soal cerita pada materi Sistem Persamaan Linear Dua Variabel (SPLDV). Kajian ini memiliki tujuan medeskripsikan kemampuan komunikasi matematis tulis dan lisan siswa yang bergaya kognitif reflektif dan impulsif dalam menyelesaikan soal cerita SPLDV. Subjek penelitian terdiri atas dua siswa SMP kelas VIII yang bergaya kognitif reflektif dan impulsif, dengan kemampuan matematika tinggi setara, dan berjenis kelamin perempuan. Instrumen penelitian meliputi MFFT, TKM, tugas komunikasi matematis, dan pedoman wawancara. Temuan studi mengindikasikan bahwasanya siswa yang bergaya kognitif reflektif mampu untuk memenuhi indikator kemampuan mengekspresikan ide-ide matematika secara tertulis dan lisan serta indikator kemampuan menggunakan simbol, notasi, dan istilah matematika secara tertulis dan lisan. Namun, siswa yang bergaya kognitif reflektif tidak mampu memenuhi indikator kemampuan memahami, menginterpretasi, dan mengevaluasi ide-ide matematika secara tertulis dan lisan karena tidak tepat dalam menyusun rencana penyelesaian serta menentukan kemungkinan maksimal jumlah pembelian dua barang, sehingga kesimpulan jawaban yang disebutkan tidak sesuai dengan informsai yang ditanyakan. Sebaliknya, siswa yang bergaya kognitif impulsif tidak mampu memenuhi seluruh indikator komunikasi matematis tulis dan lisan dalam menyelesaikan soal cerita SPLDV.
