Keterampilan Berpikir Kritis Mahasiswa Dalam Memecahkan Masalah Matematika Berdasarkan Keterampilan Abad 21

Abstract

Descriptive analysis methode of research describes about increasing subject in the level of critical thinking skills of students in solving mathematics based on 21st-century skills. The subjects research were 28 students of Mathematics Education Study Program at Ibrahimy University of Situbondo. Data collection is done by providing pre-test and study documentation to students. The test is given to collect data related to students' critical thinking skills. Then learning is done based on 21st-century skills. Furthermore, students are given a post-test solving mathematical problem. Data were collected through observations, test results and interview data tested for their validity by triangulation. The data analysis technique used is qualitative descriptive data analysis. The results of this study indicate that: (1) the results of the achievement of indicators of critical thinking of students based on critical thinking stages formulated by Facione, overall the subject of an increase of 7.53%; (2) there was the same highest increase in the achievement of the indicator thinking Facione stage, namely at the Analyze stage (A) for high, medium, and low category subjects respectively, 77.78%, 80%, and 44.44%. However, there are still two stages of critical thinking that still need attention for further research, namely at the List (L) and Self-Correct (S) stages classified as still needing special attention in implementing 21st-century skills in learning activities; (3) the level of critical thinking skills of students based on the critical thinking stages formulated by Facione was in the category of "not critical" for the pre-test results and was in the category of "sufficient critical" for the post-test results.

Prospective Teachers' Expectations of Students' Mathematical Thinking Processes in Solving Problems

“…This research is limited by its focus, specific criteria to ensure data validity and provisional design. Also, qualitative data is generated through joint decisions (Munawwarah et al, 2020;Tohir, 2019). Yin (2017) argued that a qualitative research design is used for in-depth investigation of the current situation in real-life contexts.…”

The Level of Critical Thinking Skill on Solving Two-Dimensional Arithmetics Problems Through Research-Based Learning

“…The interpretation result of the value is high which means the research is successful. Therefore, a person's critical thinking skills need to be continuously honed and improved for all levels of education (Munawwarah et al, 2020). Because students are able to think critically will be able to solve problems effectively (Arifani, As'ari, & Abadyo, 2017;Chukwuyenum, 2013;Peter, 2012).…”

“…Mathematical critical thinking skills have indicators. Based on Ennis (Munawwarah, Laili, & Tohir, 2020), critical thinking has six indicators including Focus, Reason, Inference, Situation, Clarity, and Overview. According to book P21 (Abidin & Tohir, 2019), critical thinking consists of (1) reasoning effectively, (2) thinking systems, (3) making decisions, and (4) problem-solving skills.…”

Analisis Berpikir Logis Siswa Dalam Menyelesaikan Matematika Realistik Ditinjau Dari Kecerdasan Interpersonal

“…Suatu masalah tidak akan memberikan kesimpulan jika tidak ada suatu penyelesaian masalah. Menurut Gartmam & Freiberg (Munawwarah, Laili, & Tohir, 2020) dalam proses pemecahan masalah terdapat proses menyadari dan mengatur berpikir tentang siswa untuk melakukan pendekatan dari suatu masalah, siswa dapat memilih strategi dalam menyelesaikan permasalahan dan bertanya kepada diri sendiri tentang masalah tersebut. Selain itu, (Tohir, Maswar, Atikurrahman, Saiful, & Pradita, 2020) mengatakan bahwa peran guru sangatlah penting dalam pembelajaran matematika sekolah, agar proses berpikir matematis siswa harus selalu tetap diasah setiap saat secara kontinu dan berkesinambungan, agar berpikir matematis siswa lebih sempurna.…”
