Abstract

This study aims to compile a Lecture Schedule at the Mathematics Education Study Program, Faculty of Mathematics Natural and Earth Sciences Manado State University using the Welch-Powell Algorithm. The scheduling of lectures at the Mathematics Education Study Program, Faculty of Mathematics and Natural Sciences, Manado State University often collides because several lecturers have different numbers of courses and credit rights. This it can be seen that the method of preparing lectures used is still not effective and efficient. Preparation of a course schedule is an action taken so that time can be managed as effectively and efficiently as possible. The preparation of this lecture schedule will use a simple graph with input data, namely the number of lecturers, number of courses, credits for each course, days used in the week, time slots and number of classes used. After getting the input data, point coloring is carried out in coloring on the graph using the Welch-Powell Algorithm assisted by MATLAB software to get an effective and efficient class schedule. Lecture Schedule Arrangement in the Mathematics Education Study Program, Department of Mathematics, Faculty of Mathematics, Natural and Earth Sciences, Manado State University using the Welch-Powell Algorithm produces a schedule that does not collide, so that the Welch-Powell Algorithm can help prepare an effective and efficient class schedule .

Abstract

Tujuan penelitian ini adalah untuk mengetahui kesalahan yang dilakukan siswa dalam menyelesaikan soal matriks pada kelas XI SMA Negeri 2 Tondano di mulai dari yang berkemampuan tinggi, berkemampuan sedang, dan berkemampuan rendah di lihat berdasarkan kesalahan konsep, prinsip dan operasi sebagai acuan belajar. Adapun jenis penelitian ini adalah penelitian Deskriptif Kualitatif dengan menggunakan metode Triangulasi di mana instrumen utamanya adalah peneliti itu sendiri di sertai dengan instrumen pelengkap yang terdiri dari (tes 3 butir soal dan wawancara). Penelitian ini dilaksanakan di SMA Negeri 2 Tondano, yang berada di Kabupaten Minahasa, Provinsi Sulawesi Utara, pada semester genap tahun pelajaran 2022/2023. Subjek penelitian ini adalah siswa kelas XI SMA dan telah mempelajari materi matriks. Dari penelitian ini, diperoleh hasil yaitu siswa yang berkemampuan tinggi (T) hanya memiliki tingkat kesalahan yang kecil berupa kesalahan operasi pada 1 soal saja (kurang teliti), siswa yang berkemampuan sedang (S) memiliki kesalahan konsep dan prinsip sedangkan siswa yang berkemampuan rendah (R) memiliki banyak kesalahan konsep, prinsip dan juga operasi.

Abstract

This study seeks to characterize the categories of errors students make when solving SPLDV word problems using Newman's method. Descriptive qualitative research methods are employed. This study was conducted in class VIII A at SMP Negeri 4 Touluaan during the even semester of the academic year 2021-2022. The research participants were fifteen students. Then, a test comprised of SPLDV story questions was administered to collect data. The test results were then used to select 5 students at random for interviews, based on their distinct errors. The obtained data was analyzed using the following steps: data reduction, data presentation, and conclusion. Most of the class VIIIA students at SMP N 4 Touluaan made reading errors (4.44%), understanding errors (13.33%), transformation errors (26.66%), process skills errors (48.88%), and mnemonic skills errors (68.88%).

Abstract

When learning mathematics, students sometimes experience errors in understanding concepts, data, procedures, and principles, especially in algebraic operations. This research analyzes students' errors in solving mathematics problems on algebraic operations material. The research method used is a descriptive method with a qualitative approach. The research subjects were class VIII students at SMP Negeri 4 Kawangkoan. The instruments used were written tests, interviews, and expert validation. Data analysis techniques use qualitative techniques, including data collection, reduction, and conclusion. The conclusions obtained include that students experience three types of errors in solving mathematics problems: data errors, theorem or definition errors, and technical errors.
