Abstract

National Council Of Teacher Of Mathematics (NCTM) said that learning Mathematics goals develop five basic abilities, namely problem solving, communication, connection, reasoning, and representation. These five abilities are essential to be considered and assured its accomplishment. Thus, developing these five abilities cannot be separated because they contribute to one another. While in fact, these five Mathematics abilities of students are still low. This research aimed to know the development of these five basic Mathematical abilities through structured tasks using the blog and explaining the importance of basic Mathematical skills in math learning and how Mathematics builds basic math skills to students. One of them is to implement a blog-assisted structured task method. This research sample was five classes from 11 class X MAN 1 Aceh Barat and 1st grade from 2nd grade X SMA Unggul Tunas Bangsa, Aceh Barat Daya selected with random sampling. The data collection instrument was a written test of the five basic Mathematical abilities and interviewing few students. The Data was analyzed using T-Test. The results of the analysis showed that not all basic abilities developed. From these five basic mathematical abilities, three basic Mathematical abilities developed, namely problem solving, connections, and communication. In comparison, the other two capabilities did not develop, namely reasoning and representation.

Abstract

Setiap mahasiswa pada saat memahami atau menyelesaikan masalah matematikamemerlukan waktu atau strategi penyelesaikan yang berbeda. Menurut Polya, tahap dalam menyelesaikan masalah terdiri dari 4 tahap yaitu: memahami masalah, merencanakan masalah, menyelesaikan masalah dan mengecek kembali jawabannya. Pemecahan masalah sangat erat kaitannya dengan intuisi. Kognisi intuitif atau intuisi dijelaskan oleh Fischbein (1987) sebagai kognisi yang secara subjektif kebenarannya terkandung di dalamnya, dapat diterima dengan sendirinya dan secara langsung, holistik, penggiringan dan pemerkiraan. Kognisi intuitif berbeda dengan kognisi secara analitik. Penjelasan kebenaran suatu pernyataan karena harus membuktikan merupakan kognisi yang bersifat analitik, tetapi kebenaran yang munculnya secara subjektif dan diterima secara langsung (tanpa pembuktian secara formal) merupakan kognisi secara intuitif. Bila diperhatikan, bahwa banyak siswa pandai dalam memecahkan soal matematika sering menggunakan cara-cara yang cerdas di luar dugaan dan kebiasaan, sehingga memberikan jawaban yang singkat dan akurat. Sebaliknya pada siswa-siswa yang mempunyai kemampuan matematika sedang atau rendah, cara yang digunakan untuk memecahkan soal, cenderung memberikan jawaban yang panjang lebar dan terkadang kurang akurat, bahkan banyak siswa yang kemampuan matematikanya rendah mengalami kesulitan untuk menemukan cara dalam memecahkan masalah matematika. Hal tersebut menunjukkan ada kaitan antara kemampuan matematika yang dimiliki siswa dengan intuisi yang digunakan siswa dalam memecahkan masalah matematika.Beberapa karakteristik berpikir intuitif yangcenderung digunakan mahasiswa dalam menyelesaikan masalah matematika antara lain: (1) direct, self-evident, (2) intrinsic certainty, (3) perseverance dan coerciveness, (4)  extrapolativeness, (5)global (globality)dan implisit (implicitness). Pada setiap menyelesaikan masalah matematika dari memahami masalah sampai memeriksa kembali jawaban, ada sebagian mahasiswa yang memilki intuisi dan ada juga mahasiswa yang tidak memilki intuisi.

Abstract

Mathematical problem-solving ability became one of the abilities that students must possess. However, based on the results of previous research, it was stated that there were differences between the abilities of male and female students in problem-solving abilities, so it required an in-depth understanding of mathematical problem-solving abilities based on gender. This study aims to determine the mathematical problem-solving abilities of junior high school students on pyramid material regarding gender differences. This research is qualitative research with a descriptive research type. The subjects in this study consisted of 6 students, consisting of 3 male and three female students, with high, medium and low students. Data were collected through written tests and interviews, then analyzed descriptively, including data reduction, data presentation and drawing conclusions. The results of the study were (1) female and male subjects in the high category fulfilled all indicators of problem-solving ability, but male subjects were less thorough than female subjects (2) female and male subjects in the medium category fulfilled three indicators of problem-solving ability problems, and made mistakes in making mathematical calculations, but male subjects made more mistakes than female subjects (3) Male and female subjects in the low category only met one indicator of problem-solving ability.

Abstract

The low ability to understand mathematical concepts, because mathematics is abstract, the time for the teaching and learning process is limited, the teacher plays a more important role, especially in explaining the material, the lack of time to provide exercises and quizzes in the teaching and leasrning processs, teachers must be able to take advantage of existing technology at this time. Students can be said to have the ability to understand mathematical concepts, if these students can formulate settlement strategies, apply simple calculations, use symbols to present concepts, anad change one form to another. In fact, students ability to understand mathematical concepts is still relatively low, so we need a learning model that can develop students ability to understand mathematical concepts, namely the flipped classroom learning model. The purpose of this study was to determine the students conceptual understanding ability after the flipped classroom learning model was applied. The research design used a quasi experimental design with a pre-test control group design. The population in this study were all eighth grade students of MTsN 2 Aceh Besar. Sampling was done by random sampling so that class VIII-5 was chosen as the experimental class and class VIII-6 as the control class. Data were collected using the ability test sheet for understanding mathematical concepts which were then analyzed using independent sampel t-test (right side test). As for the results of the study, it was obtained that t arithmetic > t table, namely 4,14 > 1,68, so it can be concluded that the ability to understand mathematical concepts of students who are taught by the flipped classroom learning model is better than the ability to understand mathematical concepts of students who are taught by the learning model conventional.

Abstract

This research is motivated by the low learning outcomes of students' mathematics, especially the material on trigonometric functions due to abstract mathematics and teachers who must have skills in the field of technology because they can help explain the learning material in totality. The aims of this study are (1) to determine student learning outcomes using the application of Geometer's Sketchpad software in learning material on trigonometric functions and (2) to determine the comparison of student learning outcomes with the help of Geometer's Sketchpad software can be better than student learning outcomes without Geometer's Sketchpad in class. X SMA/MA. This research is a quantitative research with a pretest-posttest control design. Sampling in this study was taken by total sampling.learning trigonometric functions in class with the help of Geometer's Sketchpad. The teacher uses infocus and guides students in the process of drawing graphs and students are also able to explain the amplitude, period, maximum value and minimum value and are able to write equations that match the graph. It is stated that the application of Geometer's Sketchpad software in learning trigonometric function material is better than learning trigonometric functions by not using software. It is proven by the posttest value which is significantly increased from the pretest value of the experimental class(2) The results of the experimental and control class posttest data that have been carried out and obtained> that is 5.87 > 1.68. Then it can be concluded that it is rejected and thus accepted, so that the learning outcomes of trigonometric function material with the help of Geometer's Sketchpad can be better than student learning outcomes without Geometer's Sketchpad in class X SMA/MA.

Abstract

This study focuses on using different cognitive styles to solve mathematical issues. Their cognitive styles can be observed when students work on mathematical problems involving mathematical representation skills. Furthermore, the analyst should assess the mathematical representation abilities of pupils at MTsN 1 Banda Aceh using the field-dependent (FD) and Field Independent (FI) cognitive styles. A descriptive, qualitative technique is used. This study employs purposive sampling procedures and focuses on two pupils from class VIII-2, one identified as FD and the other as FI. Instruments utilized include representation skill tests, interview guidelines, and GEFT questions. Analyzing the research data involves data reduction, presentation, triangulation, and conclusion formulation. The research findings point to many conclusions: (1) FI students find it easier to understand issues, can provide better conceptual explanations, solve problems faster, and explain their solutions accurately. (2) FD students have more difficulty solving issues because they rely on teacher directions. Additional concerns include their failure to analyze and comprehend information and retain concepts from challenges effectively. It is envisaged that students will understand their cognitive types to improve their mathematical representation skills in math and other courses.

Abstract

Reasoning ability is one of the abilities that students must have through high-order thinking processes to solve problems. However, students have not been able to solve problems that require high-order thinking and students have not been able to examine the problems given. This study aims to describe errors and factors that cause students to make mistakes made by MTs students in solving HOTS questions based on mathematical reasoning abilities. This research uses a qualitative approach with a descriptive type. The subjects of this study were 2 students with high category of mathematical reasoning abilities, 2 students in medium category, and 2 students in low category. The research instrument consisted of the researcher himself and test questions as the main instrument followed by an interview guide and tape recorder. Data collection was carried out by written tests and interviews. The technique for checking the validity of the data uses time triangulation, namely giving STKPM1 and STKPM2 at different times. The results of this study indicate that students with high abilities are able to solve HOTS questions correctly without any errors, students with moderate abilities have errors in doing mathematical manipulation, compiling evidence or giving reasons for the correctness of solutions and drawing conclusions from statements. The factor that causes students to make these mistakes is that students do not understand the problems given and make mistakes in calculating. Meanwhile, students with low ability categories have errors in making assumptions, manipulating mathematics, compiling evidence or giving reasons for the correctness of solutions and drawing conclusions from statements. The factor that causes students to make these mistakes is not understanding the problem given.
