Abstract

Abstrak Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir analitis siswa SMA pada pemecahan masalah matematika ditinjau dari gaya kognitif visualizer dan verbalizer, sehingga jenis penelitian yang digunakan adalah deskriptif kualitatif. Instrumen dalam penelitian ini yaitu angket (Visualizer and Verbalizer Questionnaire (VVQ)), tes kemampuan matematika, tes berpikir analitis, dan pedoman wawancara. Subjeknya adalah satu siswa bergaya kognitif visualizer dan satu siswa bergaya kognitif verbalizer. Tehnik pengumpulan data yang digunakan adalah tes kemampuan matematika, tes berpikir analitis, dan wawancara. Data yang terkumpul selanjutnya dianalisis dengan metode reduksi data, penyajian data, dan kesimpulan. Hasil penelitian menunjukkan bahwa siswa visualizer dan verbalizer pada tahap memahami masalah melakukan aktivitas kognitif berupa membedakan dan mengorganisasi, pada tahap membuat dan melaksanakan rencana, kedua siswa melakukan aktivitas kognitif berupa mengorganisasi dan memberikan atribut, langkah penyelesaian yang dilakukan kedua siswa sesuai dengan rencana yang disusun, siswa visualizer mengilustrasikan ide penyelesaian dengan panah dan menulisnya secara ringkas, siswa verbalizer menuliskan ide tersebut secara terstruktur dan jelas, pada tahap melihat kembali, siswa visualizer melakukan aktivitas kognitif berupa mengorganisasi dan memberikan atribut, sedangkan siswa verbalizer melakukan aktivitas kognitif berupa memberikan atribut. Kata kunci: Kemampuan, berpikir analitis, pemecahan masalah, visualizer dan verbalizer Abstract This study aims to describe the analytical thinking skills of high school students in solving mathematical problems in terms of visualizer and verbalizer cognitive styles, so the type of research used is descriptive qualitative. Instruments in this research are questionnaire (Visualizer and Verbalizer Questionnaire (VVQ)), mathematical ability test, analytical thinking test, and interview guide. The subject is one student with cognitive visualizer style and one student with cognitive verbalizer style. The data collection techniques used were mathematical ability tests, analytical thinking tests, and interviews. The collected data was analyzed with data reduction, data presentation, and conclusion. The results showed visualizer and verbalizer students at the stage of understanding the problem perform cognitive activities namely distinguishing and organizing, at the stage of making and implementing plans, both students perform cognitive activities namely organizing and assigning attributes, the completion steps were perform by both students according to the plans drawn up, students visualizer illustrates the idea of ​​completion with arrows and writes it briefly, verbalizer students write down the idea in a structured and clear manner, at the stage of looking back, visualizer students perform cognitive activities namely organizing and assigning attributes, while verbalizer students perform cognitive activities namely of giving attributes. Keywords: Ability, analytical thinking, problem-solving, visualizer and verbalizer

Abstract

This study aims to describe the creative thinking ability of high school students in posing collaborative problems on sequences and series, so the type of research used is a case study with a qualitative approach. The subjects in this study were high school students of grade X who were divided into groups of students with high, medium, and heterogeneous mathematical abilities (high, medium, and low). There are four data collection techniques used in this study, namely the mathematics ability test (TKM), the collaborative mathematics problem posing task (TPMKM), observation, and interviews. The instruments in this study are divided into two, namely the main instrument and supporting instruments. The main instrument is the researcher, while the supporting instruments are in the form of the mathematics ability test grid (TKM), the collaborative mathematics problem posing task sheet (TPMKM), observation guidelines, and interview guidelines. The collected data were then analyzed into three stages: data condensation, data presentation, and conclusion drawing. Data validity checking in this study uses method triangulation. There are two methods used in checking the validity of the data, namely researcher observation and FGD. The results of the study found that in homogeneous groups, the high homogeneity group demonstrated creative thinking skills in the form of fluency, flexibility, and novelty when posing collaborative problems, while the medium homogeneity group only demonstrated fluency and flexibility. In heterogeneous groups, the researchers found that student groups only demonstrated fluency. The different creative thinking skills of each group were due to differences in the composition of the mathematical abilities of the group members.
