Abstract

Proses berpikir konseptual dalam memecahkan masalah sangat dipengaruhi oleh tipe kepribadian siswa. Kesalahan yang dilakukan oleh siswa pasti sangat beragam. Hal tersebut menyebabkan perbedaan dalam proses berpikirnya. Maka dari itu, perlu diketahui bagaimana proses berpikir konseptual siswa dengan berbagai tipe kepribadian dalam penyelesaian masalah bangun ruang sisi datar. Penelitian ini menggunakan pendekatan kualitatif dengan data metode tes dan metode wawancara. Hasil penelitian ini menunjukkan bahwa dalam menyatakan ulang sebuah konsep siswa dengan tipe kepribadian extrovert cenderung tidak menuliskan informasi yang didapat di lembar jawaban, sedangkan siswa dengan tipe kepribadian introvert menuliskan secara terstruktur pada lembar jawaban. Dalam memilih prosedur pemecahan masalah, siswa extrovert lebih suka mengerjakan soal secara langsung tanpa menganalisis terlebih dahulu, berbeda dengan siswa introvert yang menganalisis terlebih dahulu, siswa extrovert cenderung memiliki alternatif pemecahan masalah lebih sedikit daripada siswa tipe kepribadian introvert. Selain itu, dalam penerapan konsep dan algoritma siswa introvert menuliskan kembali kesimpulan dari permasalahan pada lembar jawaban, sedangkan siswa tipe kepribadian extrovert tidak.

Abstract

Kemampuan pemecahan masalah dan pemahaman konsep memiliki hubungan yang sangat erat dalam melakukan pemecahan masalah. Pemahaman konsep menjadi modal yang penting dalam meningkatkan kemampuan pemecahan masalah. Penelitian ini bertujuan untuk mengetahui bagaimana kemampuan pemecahan masalah siswa berdasarkan tingkat pemahaman konsep matematis siswa dalam menyelesaikan soal cerita bangun datar segi empat. Metode yang digunakan adalah metode deskriptif dengan pendekatan kualitatif. Subyek penelitian adalah 3 siswa SMPN 3 Sampit yang memiliki pemahaman konsep tinggi, sedang dan rendah. Hasil penelitian didapatkan bahwa S1 mampu memahami soal dengan baik dengan menyebutkan apa yang diketahui dan apa yang ditanyakan pada soal kemudian membuat gambar segi empat, mampu merencanakan penyelesaian dengan baik, hal ini ditunjukkan dari bagaimana subjek menentukan cara/rumus/metode apa yang digunakan untuk menyelesaikan soal segi empat dan mampu melaksanakan penyelesaian soal yang telah diberikan, serta melakukan pemeriksaan kembali pada jawaban. Sedangkan S2 mampu memahami soal dengan baik kemudian membuat gambar segi empat, namun pada tahap merencanakan penyelesaian dan melaksanakan penyelesaian masih terdapat kesalahan, serta tidak melakukan pemeriksaan kembali. Adapun S3 masih belum mampu memahami soal dengan baik dan tidak membuat gambar segi empat, serta belum mampu merencanakan penyelesaian, belum mampu melaksanakan penyelesaian dan tidak melakukan pemeriksaan kembali. Berdasarkan hasil penelitian S1 termasuk dalam kemampuan pemecahan masalah dengan pemahaman konsep tinggi, S2 termasuk dalam kemampuan pemecahan masalah dengan pemahaman konsep sedang dan S3 termasuk dalam kemampuan pemecahan masalah dengan pemahaman konsep rendah.

Abstract

Students often have difficulty in solving problems, this is due to lack of confidence and students' critical thinking skills are still low. Critical thinking skills are needed to make decisions in solving problems on problems. In order for students to make decisions, students must have confidence in practicing critical thinking skills. This study aims to describe students' critical thinking skills in solving story problems in junior high school students who have confidence. This research method is descriptive research with a qualitative approach, in the form of the results of the work of non-test students, written tests and in-depth interviews. This study included 2 subjects who had the ability to think critically with confidence. The results of this study show that students can meet all criteria such as (1) students are able to understand problems, write down problem information from known, namely Tini bought 2 pens and bought 1 writing book, while Aisyah bought more pens than Tini equivalent to the price of books, then what was asked was the price of 2 pens and 3 writing books, respectively, (2) students are able to analyze and create mathematical models, able to consider assumptions and determine the results of completion, namely solving mathematical models on the material of a system of two-variable linear equations (SPLDV). And (3) students are able to draw conclusions from the problem, namely being able to conclude from the results of the final solution correctly. So that students are able to understand, model and solve problems appropriately.

Abstract

The aim of this research is to describe the use of project-based learning with the help of Android smartphones in trigonometric ratio material in grade X SMAN 1 Kota Besi. This research method is descriptive qualitative. The subjects of this study were tenth grade students SMAN 1 Kota Besi. Based on the results of reflections and interviews, it shows that the use of android aplication in project-based learning, namely (1) makes learning easier for students to understand and learning is more interactive because students experience it for themselves, (2) learning becomes more interesting because they use their gadgets for learning and practicum, and (3) students are more creative because they have to make reports and make presentations in front of the class. Thus the use of android aplication can support project-based learning on trigonometric ratio  material at SMAN 1 Kota Besi both inside and outside the classroom and outside of school.

Abstract

Mathematical connection skills are very necessary in solving flat-sided geometric problems. This research aims to describe the mathematical connection abilities of class VIII students at SMP Negeri 11 Sampit in solving cubaid and prism problems in terms of cognitive style. This research uses a qualitative-descriptive approach. The subjects in this research consisted of cognitive style subjects’ field dependent (FD) 1 student and cognitive style subjects’ field independent (FI) 1 student. The instruments used in this research were the GEFT test, mathematical connection ability test and interviews the results of this research show that the mathematical connection ability in solving flat-sided geometric problems of FD cognitive style subjects has difficulty in connecting between concepts, is slow in making decisions and is less analytical. Mathematical connection abilities in solving flat-sided geometric problems, FI cognitive style subjects are able to connect and analyze concepts, and are able to categorize them into a plan. These results show that there are differences in students' mathematical connection abilities in solving flat-sided geometric problems in terms of cognitive style.
