Algebraic Thinking Profile of Junior High School Students with Reflective Cognitive Style in Solving Mathematics Problems

2023-10-20T08:49:24+07:00

The differences in algebraic thinking when solving problems are determined by the characteristics of students. One of the distinguishing characteristics is cognitive style. The aim of this study was to describe the algebraic thinking profile of students who have reflective cognitive styles in solving math problems. This research is descriptive qualitative research, focusing grade 8 junior high school students with reflective cognitive style. Data collection methods using tests and interviews. This study used three types of tests, the Matching Familiar Figure Test (MFFT) to determine students' cognitive style, the Mathematics Ability Test (AMT) to measure students' mathematical abilities, and the Problem-Solving Test (PST) to obtain data related to students' algebraic thinking profile in solving math problems. Data analysis is conducted in three stages: data reduction, data presentation, and conclusion drawing. The results showed that the algebraic thinking of students with reflective cognitive style in solving problems meets the three aspects of algebraic thinking indicators, namely performing activities to generalize the pattern and determine the next term of the given pattern, represent and compare data in tabular form, and understand the meaning of variables and use variables in the form of letters or symbols as a representation of something unknown value in algebraic form. Students with a Reflective Cognitive Style in solving problems can understand the problems given well, be careful and thorough in writing the steps of completion, straightforward and coherent in answering questions so that the answers given tend to be correct.

Microsite-Based Mathematical Statistics Educational Media to Increase Student Study Motivation after the Covid-19 Pandemic

This research aims to describe student study motivation in learning mathematical statistics using microsite-based media after the Covid-19 pandemic. The research methodology used is descriptive quantitative about student study motivation using six indicators from Pintrich [1] after researching the development of microsite-based media with the research and development method and implemented in mathematical statistics lectures. By using microsite-based educational media, student study motivation in terms of the six indicators produced is in the very strong category with an average percent score reaching 80%.

Profil Kemampuan Literasi Matematika Siswa SMK dalam Menyelesaikan Soal Geometri Berdasarkan Perbedaan Kemampuan Awal

Mathematical literacy is an vital portion of building 21st-century abilities. This think about pointed to look at the scientific proficiency capacity profile of professional understudies in tackling geometric issues concurring to their starting numerical capacities. This inquire about may be a clear ponder employing a subjective approach. The devices utilized in this consider were an introductory numerical capacity test, a scientific education test, and an meet direct. The subjects of this ponder were three understudy course of X review understudies from each category, to be specific understudies with tall, medium, and moo starting scientific capacities. The comes about of this consider were understudies with tall introductory numerical capacities were able to total all markers of the definition, application, and translation forms; understudies with direct beginning numerical capacities can as it were total the definition and application pointers; students with low initial math ability not all indicators can be achieved. Out of the three categories, students with higher initial mathematical skills performed the best in mathematical literacy.

The Exploration of Geometrical Concept in Batik Pamekasan

Indirectly, mathematical themes can be found throughout Indonesia's unique culture, one of which is mathematics in batik cultural items. Exploring ethnomathematics will be really beneficial. Apart from acquiring the concept of mathematics in Indonesian culture, it can also sharpen Indonesian culture's sense of love for the nation. The purpose of this study is to describe the philosophical meaning of the geometrical concepts contained in Pamekasan batik, the geometrical concepts contained in Pamekasan batik, and the implementation of Batik pamekasan as the context in learning geometry. This is ethnomathematics study which gather the data by observation and interview. The interview held two regions in Pamekasan with four informants. As a result, scholars aim to conduct an ethnomathematics examination of traditional Pamekasan batik. This research shows that aside from the Batik itself, the mathematical objects found in Batik each have their own meaning and hopes. As a result, mathematical motifs such as the point that depicts a rice or maize seed have philosophical significance. Meanwhile, reflection reveals that human life requires balance. Each mathematical object in the pattern has its own meaning. Meanwhile, geometrical objects in Batik Pamekasan are two-dimensional figures such as circles, rectangles, squares, lines, points, angles, and curves. In addition, transformative geometry like as rotation, reflection, and translation exist in Batik Pamekasan. Besides, batik pamekasan can be used as the context in learning geometry. This can be seen from the learning outcomes that was written in Merdeka curriculum. Moreover, problem-based learning and project-based learning are two models that support ethnomathematics-based learning.

Berpikir Siswa SMA dalam Memecahkan Masalah AKM Numerasi Bangun Ruang Sisi Lengkung Berdasarkan Teori Dual-Process

2023-07-17T03:29:45+07:00

AKM numerasi merupakan salah satu program peningkatan kemampuan numerasi yang dilakukan terhadap siswa kelas 5, 8 dan 11. AKM numerasi memuat permasalahan matematika salah satunya materi bangun ruang sisi lengkung yang menerapkan kemampuan berpikir tingkat tinggi. Dalam proses pemecahan masalahnya, siswa akan bernalar untuk menghasilkan solusi. Berdasarkan teori Dual-Process, bernalar digolongkan menjadi dua jenis yaitu sistem 1 dan sistem 2. Penelitian ini bertujuan untuk mengkaji pelibatan sistem 1 dan sistem 2 siswa SMA dalam memecahkan masalah AKM numerasi bangun ruang sisi lengkung. Penelitian ini merupakan penelitian kualitatif studi kasus jamak. Subjek penelitian terdiri dari dua siswa kelas 11 SMA yang melibatkan sistem 1 dan sistem 2 dalam memecahkan masalah AKM numerasi bangun ruang sisi lengkung. Instrumen penelitian ini adalah Peneliti, masalah AKM numerasi bangun ruang sisi lengkung, alat rekam audio-visual, catatan peneliti dan pedoman wawancara. Data penelitian ini adalah jawaban tertulis subjek dan rekaman wawancara subjek. Data penelitian dianalisa menggunakan rubrik karakteristik sistem 1 dan sistem 2 subjek. Hasil dari penelitian ini adalah siswa dengan karakteristik berpikir dominan sistem 1 tanpa melibatkan sistem 2 untuk mengevaluasi jawabannya, menghasilkan solusi masalah yang salah. Di sisi lain, siswa dengan karakteristik berpikir melibatkan sistem 1 dan diiringi aktifnya sistem 2 sebagai evaluator, menghasilkan solusi masalah yang benar. Kesimpulan penelitian ini adalah sistem 2 sangat diperlukan dalam proses pemecahan masalah karena dapat digunakan sebagai pengendali jawaban yang dihasilkan oleh sistem 1.
