Abstract

The purpose of the research is to identify the conceptual and procedural error of eleventh grade students in solving problems in the Applications of Derivatives of Algebraic Functions based on Cognitive Style. The subjects of this research are eleventh grade students of SMA Negeri 1 Gunungsari. The four selected subjects consist of two field independent students and two field dependent students. This research is included in the type of descriptive qualitative research. Data collection techniques were carried out in three stages, namely the GEFT test, a written test about the description of Mathematics for the application of Algebraic Function Derivatives, and interviews. The result of this study shows that the field independent students committed one conceptual error and four procedural errors with different indicators. Meanwhile the field dependent students committed three conceptual errors and three procedural errors with different indicators. The differences between the field independent and field dependent students error are be able to know based on the error type. The field independent students tend to make procedural errors. Meanwhile the field dependent students tend to make conceptual errors.

Abstract

The non-linear mathematical model of the break even point (BEP) problem is difficult to solve analytically to obtain an exact solution, so the alternative is to solve it numerically. This research aims to solve the BEP problem and measure the effectiveness of Brent's method compared to other solution methods based on error and number of iterations. This research is an applied type whose implementation procedures include preparation, implementation, program testing, program revision, analysis, and conclusion. The errors of Brent’s, secant, false position, and bisection methods in solving the BEP problem are 0.00118; 0.00893; 0.64485; and 0.89119, respectively. While the number of iterations from several checks are 52, 53, 91, and 101, respectively. Therefore, it can be concluded that the Brent’s method is more effective than the other three methods.

Abstract

This study proposes to improve students' learning activities and learning outcomes math in class X.12 SMAN 2 Mataram in the academic year 2023/2024. The type of this research is class action research conducted in two cycles. Each cycle consists of planning, implementation, observation, and reflection. Data on student learning activities were obtained through observation, and data on student learning outcomes were obtained through evaluation tests at the end of each cycle. The learning activities of students in cycle I were in the active category, then increased in cycle II with a very active category. As for the learning outcomes of students, there was also an increase in the percentage of students' classical completeness in cycles I and II, which were 75% and 86%, respectively. Therefore, it can be concluded that implementing the problem-based learning model aided by Liveworksheet on subject statistics can increase the activity and learning outcomes math of students in the class X.12 SMAN 2 Mataram in the academic year 2023/2024.

Abstract

Higher-order thinking skills are essential competencies in 21st-century mathematics education, particularly for higher education students. One crucial aspect of this skill is the understanding of interconnected mathematical concepts. However, students often experience misconceptions that hinder their comprehension. This study aims to analyze the types and causes of students' misconceptions in the concepts of combinatorics and number theory. The research adopts a quantitative approach to measure the percentage of each type of misconception and a descriptive qualitative approach to explain how these misconceptions occur. The subjects of this study were 113 preservice mathematics teachers. The shows that a Three-Tier Diagnostic Test, was developed to identify misconceptions in detail. The findings revealed that pure misconceptions are the most dominant type, occurring in both combinatorics (34.80%) and number theory (27.80%). Students often fail to connect new concepts with their prior knowledge, a problem exacerbated by fragmented understanding from early education. These misconceptions have the potential to impact their future mathematics teaching, especially if they become educators

Abstract

Difficult integral problems that cannot be solved analytically often require numerical approaches. PHP (Perl Hypertexr Prepocessor) programming has become one of the tools that can be used to solve numerical problems. This research aims to develop a numerical integration program using the Simpson 3/8 method and Romberg method on polynomial, exponential, and trigonometric functions with PHP programming, as well as to compare the efficiency of both methods based on relative error and execution time. Based on the implementation of the algorithms of both methods in PHP programming, the research results show that the average error for the Simpson 3/8 method and Romberg method are 0,013787% and 0,001356%, respectively. The comparison of errors between these two methods indicates that the Romberg method is 9,89% more accurate than the Simpson 3/8 method. However, in terms of program execution time, the Simpson 3/8 method requires less time compared to the Romberg method. The average execution time for the Simpson 3/8 method and Romberg method are 0,00117 seconds and 1,77811 seconds, respectively, and the comparison of execution time between these two methods shows that the Simpson 3/8 method is shorter than the Romberg method when using the same number of iterations.

Abstract

Penelitian ini bertujuan untuk menghasilkan suatu produk berupa media interaktif berbasis Google sites yang layak, praktis dan efektif untuk meningkatkan kemampuan komunikasi matematis siswa kelas VIII SMP. Media interaktif berbasis Google sites dikembangkan melalui empat tahap sesuai dengan prosedur model 4D yaitu define, design, develop dan disseminate. Penelitian ini dibatasi hanya sampai pada tahap devlopment. Kevalidan atau kelayakan media interaktif dapat diketahui melalui lembar validasi ahli media dan ahli materi. Teknik analisis data menggunakan uji aiken v untuk mengukur validitas produk, uji keparktisan dan uji N-Gain untuk mengukur efektivitas media. Validator ahli media memberikan skor rata-rata 0,90 dengan kategori sangat valid dan ahli materi memberikan skor 0,94 dengan kategori sangat valid atau sangat layak. Efektivitas media interaktif diukur dengan instrumen tes kemampuan komunikasi matematis. Selanjutnya dilakukan uji coba kepada 27 siswa kelas VIII SMPN 11 Mataram. Berdasarkan hasil pre-test diperoleh nilai 16,78 dan hasil post-test sebesar 37,48 dengan nilai rata-rata standart n-gain sebesar 0,73 dengan interpretasi tinggi atau efektif. Hasil angket respon siswa memperoleh presentase sebesar 74,1% dengan kategori baik dan angket respon guru memperoleh presentase sebesar 93,3% dengan kategori sangat baik. Maka dapat disimpulkan bahwa media interaktif berbasis situs Google dinyatakan layak, efektif dan praktis untuk digunakan dalam pembelajaran matematika di kelas.
