Analisis Kemampuan Berpikir Logis Matematis Siswa Pada Materi Sistem Persamaan Linear Dua Variabel

Abstract

This study aims to describe the mathematical logical thinking ability of students of SMP Negeri 1 Ternate on systems of linear equations in two variables materials. This research uses a qualitative research. Subject of this study were three students of class VIII-J SMP Negeri 1 Ternate. The data collection stage was conducting tests, categorizing students according to the KBLM level based on the test results, and conducting interviews with research subjects. The data analysis used in this study was to analyze the data from the test results and interviews. The results showed that students at KBLM Level 2 were able to say and write down what was known and what was asked about the questions correctly, were able to use the steps to solve systems of linear equations in two variables and these steps were correct, were able to provide arguments about all steps-steps to solve systems of linear equations in two variables, and be able to draw conclusions correctly on the final answer. Students at KBLM Level 2 were able to say and write down what was known and not write down what is asked, able to use the steps to solve systems of linear equations in two variables and these steps are correct, able to provide arguments about all steps to solve systems of linear equations in two variables, and able to draw conclusions correctly on the final answer. Students at KBLM Level 2 were able to say and write down what was known and not write down what is asked, can use the steps to solve systems of linear equations in two variables but make calculation errors in these steps, do not provide arguments about all the steps solve systems of linear equations in two variables, and do not draw conclusions correctly on the final answer

Description of The Mathematical Logical Thinking Abilities of Students with Special Needs

“…Source: (Ruhama et al, 2021) The research subjects were selected using purposive sampling technique. The subjects in this study were 12th grade high school students as many as 5 students with special needs (hearing impaired).…”

“…students who have moderate mathematical logical thinking ability are unable to meet all the indicators of mathematical logical thinking ability. According to(Ruhama et al, 2021) students with level 1 mathematical logical thinking ability are able to mention what is known but are unable to mention what is asked in the problem, are able to describe the steps of completion, are able to provide arguments regarding the steps of completion, and are able to provide conclusions regarding the results of the answer. Therefore, S3 students have level 1 mathematical logical thinking ability or can be classified as students with moderate mathematical logical thinking ability.…”

“…Students are unable to draw a conclusion about the results of the answer correctly. This is in line with the research conducted by (Noviani et al, 2020) students who have low mathematical logical thinking ability are able to fulfill only 1 indicator of mathematical logical thinking ability.According to(Ruhama et al, 2021) students with level 0 mathematical logical thinking ability are able to mention what is known but are unable to mention what is asked in the problem, are able to describe the steps of completion but there are still errors, are unable to provide arguments regarding the steps of completion and are unable to provide conclusions about the answer results. Therefore, students S4 and S5 have level 0 mathematical-logical…”

Kurikulum Merdeka pada Pembelajaran Matematika

“…Serta dibekali cara berpikir, bernalar dan memakai logikanya dengan aktivitas mental yang berkesinambungan. (Nuryanti et al, 2022).…”

Pengembangan Media Truth or Dare Berbasis Model Problem Based Learning Untuk Meningkatkan Kemampuan Berpikir Logis dan Motivasi Belajar Matematika Siswa SMA Negeri 11 Medan

“…Ketiga hal tersebut meliputi; (1) pengertian (concept), (2) keputusan (decision), dan (3) penalaran (reasoning). (Mustafa, 2020) mengungkapkan ada 3 karakteristik berpikir logis, yaitu (1) keruntunan berpikir dimana siswa dapat menentukan langkah yang harus ditempuh dengan teratur dalam menyelesaikan permasalahan yang diberikan dari awal perencanaan hingga didapatkan suatu kesimpulan, (2) kemampuan berargumen dimana siswa dapat memberikan argumennya secara logis sesuai dengan fakta atau informasi yang ada terkait langkah perencanaan masalah dan penyelesaian masalah yang akan ditempuh, dan (3) penarikan kesimpulan dimana siswa dapat menarik suatu kesimpulan dari suatu permasalahan yang ada berdasarkan langkah penyelesaian yang telah ditempuh.…”
