Abstract

This qualitative research aims to analyze the stages of mathematics learning activities carried out by primary school teacher candidates at the University of Mataram. The data analysis of this research was conducted in a descriptive qualitative manner. The research subjects were randomly selected consisting of two primary school teacher candidates who have different genders but have the same academic ability. The data analysis process was carried out by collecting data, presenting data, and drawing conclusions. Data collection was obtained through instructional videos of primary school teacher candidates in primary school mathematics learning courses . The presentation of data is done by describing the stages of learning activities that the teacher must do in the classroom. The results of this study indicate that the research subjects have their respective strengths and weaknesses in the implementation of learning activities, the material abilities of the research subjects are still weak in learning activities and the research subjects do not utilize/use knowledge in previous courses to improve teaching quality.

Abstract

This study aims to describe the process of identifying elementary student teacher candidates using constructive and deconstructive strategies. This study's research subjects were 6th-semester PGSD students of Mataram University who attended elementary mathematics learning courses. This type of research is a descriptive study with a qualitative approach. Data collected in the form of test results about patterns and interviews. Then the data is analyzed. The results of the data analysis showed that there was no difference between the process of identifying student patterns using either constructive or deconstructive strategies. The process carried out by students is seeing the shape of the image compiler, making rules for each image, then determining the next pattern rules based on the rules that have been made previously in each image.Keywords: pattern identification, constructive strategy, deconstructive strategy, figural pattern

Abstract

This quasi-experimental quantitative research aims to improve the written communication skills of mathematical disposition students of grade 10 social studies-track students at a public high school in Jakarta. The design of this study was one group pretest-post test design with a sample of 36 people. Based on the mathematical written communication test, results obtained showed that the average pretest value was 55.74  and the average posttest value was 79.39. The t-test results also showed that the study showed (0.00 <0.05), then is rejected. This means that the TTW type of cooperative learning influences mathematical written communication skills. The results of the mathematical disposition questionnaire also showed that the average mathematical disposition before treatment was 57.563 (medium category) and the average value of mathematical disposition after treatment was 63.382 (high category). This shows that the mean of using TTW type of cooperative learning influences mathematical disposition.BAHASA INDONESIA ABSTRACT: Penelitian kuantitatif quasi eksperiment ini bertujuan untuk meningkatkan kemampuan komunikasi tertulis dan disposisi matematis siswa kelas X IPS 4 SMAN 50 Jakarta.

Abstract

This qualitative research aims to describe the problem solving of pattern generalization in terms of visual, auditory, and kinesthetic learning styles. The subjects in this study were three primary school teacher candidates at the University of Mataram with visual, auditory, and kinesthetic learning styles. Data was collected by giving ELSA learning style tests and pattern generalization tests to the subjects and interviewing the subjects. Data was analyzed using descriptive method and classificationing. The results showed that the research subjects who had a visual learning style were able to perform the problem-solving stages better than the audio and kinesthetic learning styles. This is because the visual learning style likes reading or understanding written instructions which results in the visual learning style being capable of good and orderly coding and processing of information.BAHASA INDONESIA ABSTRACT: Penelitian kualitatif ini bertujuan untuk mendeskripsikan pemecahan masalah generalisasi pola ditinjau dari gaya belajar visual, auditori dan kinestetik. Subjek pada penelitian ini adalah tiga orang mahasiswa calon guru Universitas Mataram dengan gaya belajar visual, auditori dan kinestetik. Pengambilan data dilakukan dengan cara memberikan tes gaya belajar ELSA dan tes generalisasi pola dan wawancara. Data dianalisis dengan cara deskriptif dan klasifikasi. Hasil penelitian menunjukkan bahwa subjek penelitian yang memiliki gaya belajar visual mampu melakukan tahapan pemecahan masalah yang lebih baik dibandingkan gaya belajar audio dan kinestetik. Hal ini disebabkan karena gaya belajar visual memiliki sifat suka membaca ataupun memahami instruksi secara tertulis yang mengakibatkan gaya belajar visual memiliki sifat mampu melakukan pengkodean dan pemrosesan informasi yang baik dan teratur.

Abstract

This qualitative research aims to describe students’ misconceptions in linear programming reviewed from written mathematical communication ability. Four students from grade X SMKN 1 Purwasari were selected as research subjects by purposive sampling. Data collected through observation and essay tests. The results showed that the sample students experienced misconceptions in the low and high categories. Misconception with high categories lies in the indicators of changing mathematical ideas into mathematical models (75%), represent mathematical ideas into images or vice versa (100%), and mathematical problem-solving procedures (75%), while misconception with low categories is found in indicators choose the right concept in solving mathematical problems (25%). Based on this result, further treatment is needed to overcome students’ misconceptions before students continue learning to a higher stage.

Abstract

Pemahaman konsep matematika merupakan aspek penting yang harus dikuasai oleh siswa sekolah dasar. Untuk meningkatkan kemampuan tersebut, perlu diterapkan model pembelajaran yang tepat dan penggunaan media konkrit yang mendukung proses belajar mengajar. Oleh karena itu, penelitian ini bertujuan untuk mengkaji pengaruh model problem based learning (PBL) berbantuan media papan penjumlahan bersusun (PAJUSUN) terhadap pemahaman konsep matematika siswa kelas III di SDN Prapak. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis eksperimen dan desain penelitian yang digunakan adalah One-Group Pretest-Posttest Design. Sampel penelitian berjumlah 31 siswa kelas III SDN Prapak. Teknik pengumpulan data menggunakan tes pemahaman pemahaman konsep matematika yang meliputi empat indikator yaitu menyatakan ulang konsep, memberikan contoh dan non-contoh, menyajikan konsep dalam bentuk representasi matematis, dan mengklasifikasi konsep atau algoritma pemecahan masalah. Data yang diperoleh dianalisis menggunakan Wilcoxon Signed Rank Test. Berdasarkan hasil analisis data diperoleh nilai signifikansi 0,000 < 0,025, yang berarti terdapat pengaruh yang signifikan antara hasil pretest dan posttest. Selain itu, nilai rata-rata siswa meningkat dari 59,879 pada pretest menjadi 87,701 pada posttest, yang menunjukkan peningkatan pemahaman konsep secara keseluruhan setelah perlakuan yang diberikan. Dengan demikian, H₀ ditolak dan Hₐ diterima, yang membuktikan bahwa model Problem Based Learning berbantuan media papan penjumlahan bersusun (PAJUSUN) berpengaruh terhadap pemahaman konsep matematika siswa kelas III di SDN Prapak.
