Analisis Kemampuan Komunikasi Matematika Siswa SD dalam Menyelesaikan Masalah Matematika

Abstract

ABSTRAKPenelitian ini bertujuan untuk menganalisis kemampuan komunikasi dalam memecahkan masalah matematika. Penelitian ini adalah penelitian kualitatif. Subjek penelitian adalah siswa SD Islam Quran Al Bahjah Tulungagung. Penentuan subjek menggunakan purposif sampling berdasarkan kemampuan komunikasi dan penyelesaian masalah matematika. Instrumen penelitian ini berupa soal tes pemecahan masalah matematika dan lembar wawancara. Teknik pengumpulan data dilakukan dengan mengumpulkan data dari tes tulis dan wawancara siswa. Hasil penelitian ini adalah 1) tahap memahami masalah, subjek memahami masalah dengan baik dan mampu menyatakan gagasan-gagasan matematika secara lisan dan tulis, mampu menjelaskan representasi matematika yang dibuat; 2) tahap merencanakan strategi penyelesaian soal cerita, subjek dapat menjelaskan rencana penyelesaian soal cerita yang dikerjakan serta mempunyai kemampuan menyatakan gagasan-gagasan matematika secara lisan dan tulis, mampu menjelaskan representasi matematika yang dibuat dan mampu menjelaskan hubungan ide dalam penyelesaian soal; 3) tahap melaksanakan strategi penyelesaian, subjek yakin dengan hasil yang dikerjakan dan dapat menunjukkan bahwa jawabannya itu benar serta mampu menyatakan gagasan matematika secara tulis dan lisan; dan 4) pada tahap memeriksa kembali, subjek melakukan pemeriksaan kembali jawaban yang diperoleh serta mampu menyatakan gagasan-gagasan matematika secara lisan dan tulis. ABSTRACT This study aims to analyze communication skills in solving mathematical problems. This research is qualitative research. The subjects of the research is the Islamic Elementary School students of Quran Al Bahjah Tulungagung. Determination of subjects using purposive sampling based on communication skillsand solving mathematical problems. The instrument of this research is in the form of mathematical problem solving test questions and interview sheets. Data collection techniques are done by collecting data from written tests and student interviews. The results of this study are 1) the stage of understanding the problem, the subject understands the problem well and is able to express mathematical ideas verbally and written, able to explain mathematical representations made; 2) the stage of planning a strategy for solving a story problem, the subject can explain the plan to solve the story problem that is done and have the ability to express mathematical ideas verbally and written, able to explain mathematical representations made and able to explain the relationship of ideas in solving problems; 3) the stage of implementing a settlement strategy, the subject is sure of the results done and can show that the answer is correct and able to express written and oral mathematical ideas; and 4) at the re-examination stage, the subject re-checks the answers obtained and is able to express mathematical ideas verbally and written.

Meningkatkan Aktivitas Dan Hasil Belajar Ipa Melalui Discovery Learning Berbantuan LKS Bertema

“…Terdapat beberapa hal terkait model pembelajaran yang perlu guru perhatikan, yaitu (1) pengaitan materi pembelajaran dengan kehidupan sehari-hari, (2) kejelasan penyampaian materi dari guru, (3) pemberdayaan kerja kelompok (Utomo, 2011), dan (4) meningkatkan minat siswa dalam belajar (Indrawati, 2019). Salah satu model pembelajaran yang memenuhi keempat hal tersebut yaitu Discovery Learning karena merangsang aktivitas siswa dalam kelompok, menggugah minat dan aktivitas siswa, dan meningkatkan hasil belajar siswa (Ana, 2019).…”

High School Students' Mathematical Skills in Addressing Minimum Competency Assessment Problems using Working Backward Strategy

“…There are ten problem-solving strategies to be an option in solving the problems presented (Sholihah & Afriansyah, 2018). According to (Utomo, 2019), there are various problems with different characteristics, some can be solved with only one strategy, and there are also problems that can be solved with various strategies. However, what is still being debated is in determining the best and most efficient problem-solving strategies to solve problems that must be based on the experience and knowledge of students.…”

Analysis of The Relationship Between Student Interest and Written Communication in Solving Realistic Mathematics Problems

“…Communication can be interpreted as a technique for expressing a message from the messenger to the recipient to express or notify comments either orally or in writing (Leyva et al, 2022;Utomo, 2019). Students' success in improving their mathematical communication skills can affect several aspects, both from their own and external factors (Armania et al, 2018;Luo et al, 2022;Partono et al, 2021).…”
