Berpikir Impulsif Dalam Komunikasi Matematis Siswa Sekolah Menengah Pertama

Abstract

Abstrak: Tujuan penelitian ini untuk menelusuri komunikasi matematis siswa kelas VII SMP berdasarkan gaya kognitif impulsif. Jenis penelitian ini adalah penelitian kualitatif deskriptif. Subjek dalam penelitian ini adalah siswa kelas VII SMP N 2 Gubug Pemilihan subjek penelitian dengan teknik purposive sampling, Teknik keabsahan data yang digunakan dengan triangulasi metode. Analisis data mengikuti konsep Miles dan Huberman dengan proses: (1) Reduksi data, (2) Sajian data; dan (3) Penarikan kesimpulan dan verifikasi. Hasil dari penelitian ini menunjukkan siswa mampu membuat tulisan dalam pemecahan masalah matematika, tetapi cenderung tergesa-gesa dan salah, membuat tabel dalam proses pemecahan masalah yang diberikan, dapat mengisi hal – hal yang diketahui dan ditanyakan tetapi cenderung salah, mengerjakan soal yang diberikan dengan tahapan – tahapan secara terurut terkait dengan masalah yang diberikan, dapat menyelesaikan langkah-langkah tersebut walaupun cenderung salah, mampu secara lengkap dan jelas dalam mengkomunikasikan ide – idenya kepada orang lain secara lisan, tetapi cenderung tergesa – gesa dan cepat.

Mathematics Communication Junior High School Students in Solving Open-Ended Question Based on Reflective-Impulsive Cognitive Style

“…This indicates that the written mathematics communication of the SR subject related to the information on the questions was accurate and complete. These results are in accordance with Shodiqin's [16] research that reflective students are able to write down things that are known and asked completely and correctly. Following are the interviews of researchers with SR subjects related to information that is known and asked in open-ended questions.…”

“…Based on the above analysis, communication both oral and written of SI subject can be said inaccurate, complete and fluent in terms of mentioning the steps for solving open-ended questions. This is in accordance with the results of Shodiqin's [16] research that impulsive students can complete the completion steps and were able to communicate them completely and clearly even though there are still some mistakes.…”

Validity and Practicality of Problem-Based Integral Calculus Teaching Materials Assisted with Mathematical Software

“…Based on the analysis of the lecturer's response questionnaire, an average score of 3.37 was obtained which was also in the practical category. This study was supported by [26] found that the use of the Geogebra program had a good effect in terms of learning outcomes and motivation, research [27] found that learning using mathematics teaching materials in the form of tabloids assisted by Wolfram Mathematica software with a contextual approach was better than conventional learning on integral material and also supported by [30] that the use of software, especially Geogebra helps students to focus on the material, and they also admit that they can visualize graphics well using Geogebra.…”

Analisis Kemampuan Berpikir Kritis Matematis Ditinjau dari Gaya Kognitif Siswa

“…Sehingga siswa impulsif tidak perlu memikirkan secara mendalam untuk dapat memahami masalah. Hal ini sejalan dengan penelitian Shodiqin & Zuhri (2018), siswa impulsif mampu menentukan hal-hal yang diketahui dan ditanyakan, tetapi cenderung tergesa-gesa. Sebagai tambahan, penelitian yang dilakukan Cahyono dkk., (2019), dalam memahami masalah siswa impulsif menceritakan kembali informasi yang didapat menggunakan bahasa sendiri maupun mengadopsi dari soal.…”
