Abstract

The study aims to find out pseudo-thinking in solving mathematical problems. The methods used in this study are qualitative descriptive. The research subject is junior high school students using the purposive sampling technique, the students are grouped into three ranks i.e. low, medium and high rankings which each ranked 3 students as respondents. The total number of respondents was 9 students. Data collection techniques using tests, interviews, and documentation. From the results of the study gained that: 1) students who are ranked low in solving mathematical problems are experiencing pseudo-analytic or pseudo-false, 2) students who are in the moderate level also experience pseudo-analytic or pseudo-incorrect, 3) students who are in high ranking experience pseudo-analytic and pseudo-4) students who experience pseudo-thinking choose procedures using their own reasoning and convince it as a correct understanding , so there is no attempt to re-examine what he has done

Abstract

This study aims to describe the refractive thinking of class VIII B students of SMP Negeri 1 Sumbang. They are distributed in terms of thinking and feeling personality types. This type of research is qualitative research. The sample of this study was six students from class VIII B who were selected using a purposive sampling method. Data collection techniques are questionnaires, refractive thinking tests, interviews, and documentation. Data analysis techniques are divided into three stages: data reduction, data presentation, and conclusion. The results of this study indicate that students with the thinking personality type can gather information on the problem, link information in the issue with prior knowledge, propose solutions or alternative solutions to problems, eliminate solutions or alternative solutions to issues, carry out appropriate solving strategies and re-examine the solutions that have been obtained. Feeling personality type, students can gather information on the problem, relate the information in the issue with previous knowledge, and propose solutions or alternative solutions to problems

Abstract

Kemampuan numerasi sangat dibutuhkan dalam segala aspek kehidupan. Penelitian ini bertujuan menganalisis kemampuan numerasi dalam mengerjakan soal tipe AKM ditinjau dari gaya kognitif siswa. Metode penelitian ini adalah penelitian kualitatif deskriptif. Subjek yang diambil dalam penelitian ini adalah siswa kelas VIII G SMP Negeri 1 Jatilawang menggunakan teknik purposive sampling. Pengumpulan data dilakukan menggunakan tes GEFT, tes kemampuan numerasi, wawancara dan dokumentasi. Hasil penelitian menunjukan bahwa siswa dengan gaya kognitif field dependent tidak mampu memenuhi indikator numerasi yaitu menganalisis informasi, menggunakan berbagai macam angka dan simbol-simbol, serta pemeriksaan pendapat untuk mengambil keputusan. Sedangkan siswa dengan gaya kognitif field independent hampir memenuhi semua indikator kemampuan numerasi. Kekurangannya kadang siswa kurang teliti saat membaca data di gambar atau diagram pada soal. Siswa dengan gaya kognitif field independent jauh lebih unggul dibandingkan siswa field dependent dalam mengerjakan dan menjelaskan pengerjaan soalnya.

Abstract

This study aims to determine the increase in activeness and learning outcomes using a culturally responsive teaching approach in grade III students of SD Negeri 3 Karangtengah. This research was carried out in 2 cycles, each cycle consisted of 2 meetings. Each meeting consists of 4 stages, namely planning, implementation, observation/observation, and reflection. The data analysis technique used in this study is a quantitative data analysis technique using tests and qualitative data analysis techniques through observation. The results of the classroom action research using the culturally responsive teaching approach were proven to improve student learning outcomes, where based on the test results showed that the percentage of classical completeness in the first cycle increased to 66.65 in the second cycle to 79.8. In addition, an increase also occurred in the percentage of student activity level in the first cycle reaching 49%, increasing in the second cycle to 59%.

Abstract

Proses metakognitif merupakan komponen penting dalam pemecahan masalah matematis karena membantu peserta didik merencanakan, memantau, dan mengevaluasi proses berpikirnya agar memperoleh solusi yang tepat. Penelitian ini bertujuan mengeksplorasi proses metakognitif peserta didik SMP dalam pemecahan masalah matematis ditinjau dari gaya belajar Honey dan Mumford. Penelitian menggunakan pendekatan kualitatif deskriptif dengan delapan peserta didik yang dipilih melalui teknik purposive sampling, masing-masing terdiri atas dua peserta didik bergaya belajar aktivis, reflektor, teoris, dan pragmatis. Data dikumpulkan melalui angket gaya belajar, tes pemecahan masalah matematis, wawancara mendalam, dan dokumentasi. Analisis data menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan, sedangkan keabsahan data diperoleh melalui triangulasi teknik. Hasil penelitian menunjukkan bahwa proses metakognitif pada tahap planning telah muncul pada seluruh gaya belajar dengan kualitas yang berbeda. Peserta didik bergaya belajar teoris menunjukkan perencanaan dan pemantauan yang paling sistematis, sedangkan peserta didik bergaya belajar reflektor dan pragmatis masih mengalami kesulitan dalam menentukan strategi yang sesuai. Pada tahap monitoring, peserta didik bergaya belajar aktivis dan pragmatis belum konsisten dalam mengenali serta memperbaiki kesalahan. Pada tahap evaluation, seluruh subjek mampu merefleksikan proses berpikir melalui wawancara, tetapi aktivitas tersebut belum sepenuhnya tercermin pada jawaban tertulis. Temuan ini menunjukkan bahwa karakteristik gaya belajar memengaruhi kualitas proses metakognitif peserta didik dalam merencanakan, memantau, dan mengevaluasi penyelesaian masalah matematis. Penelitian selanjutnya disarankan mengembangkan strategi pembelajaran yang mendukung proses metakognitif sesuai karakteristik gaya belajar serta melibatkan subjek dan materi yang lebih beragam.
