This study aims to explain the procedural fluency of students in numerical methods courses. Procedural fluency refers to knowledge of procedures, about when and how to use them appropriately, and the skills to carry out procedures flexibly, accurately, and efficiently. The method in this study uses a descriptive method with a qualitative approach and data analysis techniques for the Miles and Huberman models. In this study also performed triangulation of techniques by conducting interviews to strengthen the test result data. From the data analysis, it can be concluded that regarding the smoothness in students' procedural procedures in solving problems related to numerical methods courses, students are able to solve problems with more than one method. However, some students have not been able to streamline steps and make accurate calculations. In addition, mastery in operating a scientific calculator needs to be improved so that students can be more efficient and get more accurate answers.
The role of computers becomes an inseparable part of daily life, including as a media for learning mathematics, including making it easier to visualize 3D objects (building three-dimensional space). GeoGebra is software that can be used for mathematics education by combining geometry, algebra, and calculus. This research is an experimental research and the design used is the nonequivalent control group design. Sampling and sampling in this study using purposive sampling techniques. Based on the different test of the two average gain indexes, it was concluded that improving the problem-solving ability of students who studied using the GeoGebra-assisted problem-based learning approach was better than students who studied with conventional learning. The results of the attitude scale, it was found that in general students are positive towards mathematics learning by using the GeoGebra-assisted problembased learning approach. The results of the bivariate correlation calculation concluded that there is a positive correlation between students 'attitudes towards learning using the application of GeoGebra-assisted problem-based learning and improving students' mathematical problem-solving abilities.
The purpose of this research was to determine the improvement of student’s mathematical representation skills and student’s attitudes towards learning using SAVI learning assisted by GeoGebra. This research is a quasi-experimental research with the object of research of students of SMP Negeri 3 Cianjur. Students in class VIII-5 will be the experimental class and students in class VIII-7 will be the control class. The method used in this study is quasi-experimental research methods with non-randomized control group pretest - post-test design. Data processing will be executed with the normality test, Mann Whitney test, and the percentage of achievement indicators. Based on the results of data processing and interpretation, it is shown that SAVI learning assisted by GeoGebra better than ordinary learning in improving student’s mathematical representation skills. Then the attitude of students towards SAVI learning assisted by GeoGebra is generally positive.
Pemahaman konsep akan sebuah ilmu pengetahuan berperan penting, salah satunya untuk menghubungkan atau mengaitkan sebuah konsep yang satu dengan yang lainnya yang telah dipelajari. Oleh karenanya, kemampuan pemahaman konsep menjadi salah satu tujuan penting dalam pembelajaran. Pemahaman konsep memberikan pengertian bahwa materi yang diajarkan bukanlah hanya sebuah hafalan. Berdasarkan pentingnya peranan pemahaman akan sebuah konsep, dilakukanlah sebuah penelitian dengan tujuan untuk mengetahui dan menelaah tingkat kemampuan pemahaman konsep mahasiswa dan mengetahui kesalahan-keselahan mahasiswa dalam memahami mata kuliah pemrograman komputer. Penelitian dilakukan dengan menggunakan metode deskriptif kuantitatif dengan subjek penelitian mahasiswa peserta didik tingkat I mata kuliah Pemrograman Komputer Program Studi Pendidikan Matematika Universitas Suryakancana Tahun Akademik 2016-2017. Teknik Pengumpulan data dilakukan dengan menggunakan instrument tes. Hasil penelitian 1) Secara umum tingkat kemampuan pemahaman konsep mahasiswa pada mata kuliah pemprograman komputer adalah sedang dengan persentase kemampuan pemahaman konsep sebesar 68,724%. 2) Kesalahan yang paling banyak dilakukan pada penyelesaian yang dilakukan mahasiswa adalah mengenai konsep C++ dengan persentase sebesar 58,929%.
Pada penelitian yang dilakukan oleh Setiawan dkk, menyatakan bahwa metode loss distribution approach dengan pendekatan kernel density estimation mampu menghasilkan nilai economic capital yang lebih efisien sebesar 1,6% -3,2% dibandingkan dengan pendekatan distribusi probabilitas tertentu. Fungsi kernel yang digunakan dalam penelitian tersebut adalah kernel Gaussian dengan pertimbangan dapat memberikan visual grafik yang lebih mulus dibandingkan visual grafik yang dihasilkan oleh fungsi kernel lainnya, seperti Uniform, Epanechnikov, dan Segitiga. Padahal tidak ada jaminan bahwa grafik yang lebih mulus dapat memberikan hasil economic capital yang lebih efisien. Oleh karena itu, akan dilakukan penelitian lebih lanjut yang bertujuan 1) menghitung nilai economic capital menggunakan loss distribution approach dengan pendekatan kernel density estimation yang menggunakan fungsi kernel Gaussian, Uniform, Epanechnikov, dan Segitiga, 2) membandingkan nilai-nilai economic capital yang dihasilkan dengan cara uji perbedaan rata-rata. Perhitungan nilai economic capital dilakukan melalui simulasi komputasi berbasis bahasa pemrograman python. Hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan pada nilai economic capital yang dihasilkan. Oleh karena itu, pemilihan fungsi kernel yang tepat sangat diperlukan agar dapat memberikan nilai economic capital yang lebih efisien.
