Abstract

This research includes qualitative research. Qualitative research is research that examines phenomena in a state of potency and attempts to describe these phenomena. The phenomenon studied in this study is the way of solving and thinking processes of students in mathematical problem solving related to mixed arithmetic operations by fourth grade elementary school students. The method of solving the problem will be studied according to the four steps of Polya's problem solving, namely: (a) understanding the problem; (b) planning solutions; (c) solving problems; (d) re-examine the results of the work. In this paper, we will discuss how to solve a student's problem and his thinking process in solving mathematical problems related to mixed arithmetic operations.

Abstract

This research is focused on elementary school students multiple mathematical representations through realistic mathematics education on fractions lesson. The problem that will be solved is "what is the ability of multiple mathematical representations of fourth grade elementary school students through realistic mathematics education on the concept of fractions and equivalent fractions?" This research was conducted at public school 1 Ternate City. The research subjects were 4 students, one high-ranking student, two medium-ranking students, and one low-ranking student. The research was conducted in two learning actions. The results of data analysis found: (1) high-ranking students (S1), from the beginning of first action to the end of second action, liked to study in groups. In the first action the percentage of mathematical representation ability to the ideal maximum score is 100% both when working on the LKPD and in the final test of first action. The mode of representation ability level is at level 4 (creating and using representations correctly); (2) students of moderate rank (S2 and S3), enjoy working in groups. The average percentage of achievement of the mathematical representation ability score by masters working on the LKPD is 94% and at the end of the action test it is 100%. The percentage of achievement of the mathematical representation ability score by S3 doing LKPD is 99.5% and at the end of the action test is 96%. S2 and S3 mathematical representation ability level mode is at level 4; (3) low-ranking students (S4) who like to work alone. The average percentage of achievement scores of mathematical representation abilities by S4 working on LKPD is 72% and on the final test of action 78%; (4) students enjoy learning the concept of fractions and equivalent fractions through realistic mathematics education. The use of bread model props for the concept of fractions and or equivalent fractions makes students actively work in pairs and enjoy learning; (5) students are able to use props to solve problems, (6) students are able to manipulate images to solve problems.

Abstract

The design of this research is classroom action research (CAR), following the Kemmis & Mc model. Taggart. The aim is to improve the learning abilities and independence of students of the Unsub mathematics education study program using the ACE (activities, class discussion, exercise) learning cycle in the Introduction to Algebraic Structure (PSA) course. The research subjects were 5th semester students (odd) who contacted the PSA course. The procedure for collecting data is through observation, independent learning questionnaires, interviews, and learning outcomes. Furthermore, the data were analyzed qualitatively following the flow model, with the stages of reducing data, presenting data, and drawing conclusions and verification. The results showed that the PSA lectures used the ACE learning cycle showing that: (1) in the activities phase; students in groups carry out activities outside the classroom; discuss the problems contained in the LKM well, (2) in the class discussion phase, students in groups carry out discussions in the classroom based on problems shared outside the previous class, then present the results, and (3) in the exercise phase ; the lecturer gives practice and test questions to complete. The results of the final tests, observations, and interviews showed that student learning independence increased from 62.15% (cycle I) to 86.05% in cycle II. In conclusion, the application of the ACE learning cycle in the Introduction to Algebraic Structures course can improve the ability and independence of student mathematics teacher candidate learning.

Abstract

Tujuan dari penelitian ini adalah untuk meningkatkan kemampuan Mathematical Creative Problem Solving (MCPS) melalui penggunaan multimedia matematika interaktif bagi siswa SD. Penelitian kuasi eksperimen dengan posttest control group design ini melibatkan 136 siswa kelas IV dan V dari dua jenjang Sekolah Dasar Negeri di Kota Tidore Kepulauan, yang masing-masing terdiri dari satu kelas eksperimen dan satu kelas kontrol. Instrumen yang digunakan meliputi: butir soal tes kemampuan MCPS dan mathematical habits of mind (MHM). Data penelitian untuk skor tes awal, tes akhir, dan gain ternormalisasi kemampuan MCPS dianalisis dengan menggunakan ANOVA dua jalur dan Mann-Whitney. Berdasarkan hasil analisis data, ditemukan bahwa terdapat perbedaan peningkatan kemampuan MCPS dan disposisi MHM secara signifikan antara siswa yang mendapat pembelajaran menggunakan multimedia matematika interaktif (kelas eksperimen) dan siswa yang mendapat pembelajaran konvensional (kelas kontrol) berdasarkan kedua level sekolah (tinggi dan sedang). Hasil Penelitian ini disimpulkan bahwa peningkatan kemampuan MCPS siswa SD yang mendapatkan pembelajaran menggunakan multimedia matematika interaktif lebih baik dibandingkan dengan pembelajaran konvensional ditinjau dari kedua level sekolah.
