Analisis Kemampuan Pemecahan Masalah Ditinjau Dari Gaya Kognitif Siswa pada Model Project Based Learning Bernuansa Etnomatematika

Abstract: Penelitian ini bertujuan untuk (1) mengetahui keefektifan pembelajaran dengan model Project Based Learning bernuansa etnomatematika dalam meningkatkan kemampuan pemecahan masalah, dan (2) mendeskripsikan kemampuan pemecahan masalah siswa ditinjau dari gaya kognitif. Penelitian ini merupakan jenis penelitian mixed method dengan desain sequential explanatory. Subjek dalam penelitian ini ditentukan berdasarkan analisis gaya kognitif menggunakan Group Embedded Figure Test (GEFT) pada siswa kelas VIIIA SMP N 1 Wates, Yogyakarta. Teknik pengumpulan data menggunakan observasi, tes dan wawancara. Efektivitas dianalisis berdasarkan (1) uji kesamaan rata-rata; (2) uji ketuntasan dan uji beda rata-rata. Hasil penelitian menunjukkan bahwa pembelajaran dengan model Project Based Learning bernuansa etnomatematika efektif terhadap kemampuan pemecahan masalah. Siswa dengan gaya kognitif Field Independent (FI) cenderung memiliki kemampuan pemecahan masalah yang lebih baik daripada siswa dengan gaya kongnitif Field Dependent (FD). Siswa FDL mampu memahami masalah, namun kurang mampu merencanakan penyelesaian dan melaksanakan rencana penyelesaian serta tidak mampu memeriksa kembali. Siswa FDK mampu memahami masalah dan merencanakan rencana penyelesaian, namun kurang mampu melaksanakan rencana penyelesaian dan memeriksa kembali. Siswa FIL mampu memahami masalah, merencanakan penyelesaian dan melaksanakan rencana penyelesaian, namun kurang mampu memeriksa kembali. Siswa FIK mampu memahami masalah, merencanakan penyelesaian, melaksanakan rencana penyelesaian, serta memeriksa kembali dengan baik.

Buginese ethnomathematics: barongko cake explorations as mathematics learning resources

Abstract: Mathematics is still viewed as a culture-free subject. This forms a negative perception for students on mathematics. Most students assume that mathematics and culture are not related. This may occur because mathematics taught in school is not contextual and far from the reality of everyday life. Historically, mathematics has become a part of daily life. As a maritime nation, Indonesia has a diverse culture. But many teachers are not yet aware of the integration of the culture into mathematics learning. Barongko cake is one of the Buginese cultural heritages. Buginese people have unconsciously been practicing mathematics in making these cakes. Therefore, this research aims to explore activities in making Barongko cakes in the Buginese community that involves mathematical concepts. This research is a qualitative descriptive with an ethnographic approach. The data collection methods are carried out through observation, documentation, interview with an expert in making Barongko cake. This research found that Barongko making process involves mathematics in the concept of division, congruence and similarity, as well as a triangular prism, and half sphere. This cake has the potential to be used as a source of contextual mathematics learning in schools.

The differences of cognitive style fields-independent and dependent on students' mathematical problem solving abilities

Abstract: The study aims to determine the differences in field-independent cognitive styles with a dependent on students' mathematical problem solving abilities. This researcher uses a quantitative approach with a correlational survey method with factual exposure research types. The study population was the seventh grade students of Madrasah Tsanawiyah in Lombok Timur, amounting to 680. The sampling used was simple random sampling technique. The sampling technique uses percentage techniques. From a population of 680 people taken 10%, so the number of samples in this study was 68 people. The hypothesis analysis test used the t test with SPSS 22. The results showed that there was a difference between students' mathematical problem solving abilities in the group of students who had a field independent cognitive style and a group of students who had a field dependent cognitive style. the principal in recruiting students to enter the Madrasah Tsnawiyah, not only the value of the results of the National Primary School exam but rather the grouping of students based on independent and field dependent cognitive field styles

Students’ Metacognitive Process in Mathematical Problem Solving Based on Cognitive Style

Abstract: This study is a qualitative literature review aimed to describe junior high school students’ metacognitive process in mathematical problem solving based on field independent and field dependent cognitive style. The research was done based on these following steps: 1) Data library relevant to variable and in accordance to the data source criteria was collected; 2) the data library was classified according to the grade and the subjects; 3) the data was analyzed. The instruments used in this study were the researchers and interview. The interview was conducted to confirm the classified data. Based e this study, it can be concluded that students using field independent style, competently can employ metacognitive process in planning, monitoring, and evaluating because they can write down the known fact and the question using mathematical symbol, choose the appropriate strategy, and answer the question thoroughly. Students using field dependent style were having difficulties in writing down the known fact and the question using mathematical symbol, choosing an appropriate strategy, and answering the question thoroughly.

Project based learning berbasis etnomatematika berbantuan augmented reality untuk meningkatkan kemampuan pemecahan masalah geometri

Abstract: Salah satu catatan pembelajaran matematika yang tidak kunjung selesai adalah pembelajaran yang bersifat pasif, rendahnya motivasi belajar siswa, rendahnya kemampuan siswa memvisualisasi gambar geometri, lemahnya kemampuan pemecahan masalah geometri siswa dan lain-lain. Studi literatur ini akan membahas tentang model Project Based Learning (PJBL) berbasis etnomatematika berbantuan teknologi Augmented Reality (AR) untuk meningkatkan kemampuan pemecahan masalah geometri. PJBL merupakan pembelajaran yang mendukung pemecahan masalah berupa aktivitas siswa secara langsung melalui proyek, hal tersebut terlihat pada kesesuaian tahapan PJBL dan indikator kemampuan pemecahan masalah. Tugas proyek akan lebih bermakna jika masalah proyek berada dekat dengan siswa yaitu dengan etnomatematika. Media AR akan menjadi perantara terhadap kesenjangan materi geometri yang berupa gambar 2D atau 3D dengan benda-benda pada tugas proyek yang bersifat nyata. Selanjutnya berdasrkan beberapa hal diatas, maka model pembelajaran baru dapat meningkatkan kemampuan pemecahan masalah geometri siswa. Model PJBL yang merupakan modifikasi dari Wati (2018) : (1) menganalisis masalah berbasis etnomatematika (2) membuat desain dan jadwal pelaksanaan proyek (3) melaksanakan penelitian berbantuan AR (4) menyusun draf/prototipe produk secara teori (5) menilai, memperbaiki dan menambahkan prototipe dengan bantuan AR (6) Finalisasi dan publikasi proyek. (7) guru memberikan penguatan, masukan, dan perbaikan.

The Achievement of Middle School Students’ Mathematical Problem Solving Abilities through Project-Based Learning Models

Abstract: This research aims to determine the use of project-based learning (PjBL) in the achievement of students' mathematical problem-solving abilities. The variables in this research were PjBL and mathematical problem-solving abilities. The instrument in this research was a description test of mathematical problem-solving abilities, which was analyzed by testing the hypothesis using the Mann Whitney U test. The results showed that the average value of students learning using PjBL was higher than students learning using conventional models. The results of the Mann Whitney test show that learning using PjBL is effective in improving students' mathematical problem-solving abilities.
