A Relationship Between Problem Solving Ability and Students’ Mathematical Thinking

Abstract

This research have a purpose to know is there an influence of problem solving abilty to students mathematical thinking, and to know how strong problem solving ability affect students mathematical thinking. This research used descriptive quantitative method, which a population is all of students that taking discrete mathematics courses both in department of Information Systems and department of mathematics education. Based on the results of data analysis showed that there are an influence of problem solving ability to students mathematical thinking either at department of mathematics education or at department of information systems. In this study, it was found that the influence of problem solving ability to students mathematical thinking which take place at mathematics education department is stonger than at information system department. This is because, at mathematics education department, problem-solving activities more often performed in courses than at department of information system. Almost 75% of existing courses in department of mathematics education involve problem solving at the implementation of courses, meanwhile, in the department of information systems, there are only 10% of these courses. As a result, mathematics education department students' are better trained in problem solving than information system department students. So, to improve students' mathematical thinking, its would be better, at firstly enhance the problem solving ability. Keywords: students' mathematical thinking, problem solving ability Abstrak Penelitian ini bertujuan untuk mengetahui apakah terdapat hubungan yang signifikan antara kemampuan mathematical thinking dengan problem solving mahasiswa program studi sistem informasi dan untuk mengetahui seberapa besar kemampuan problem solving mempengaruhi kemampuan mathematical thinking mahasiswa. Populasi dalam penelitian ini adalah seluruh mahasiswa yang mengontrak mata kuliah matematika diskrit pada program studi Sistem Informasi dan program studi pendidikan matematika. Berdasarkan hasil analisis data diperoleh bahwa terdapat pengaruh yang signifikan antara kemampuan problem solving dan mathematical thinking baik pada mahasiswa prodi sistem informasi maupun pendidikan matematika. Pada penelitian ini, ditemukan fakta bahwa pengaruh kemampuan problem solving terhadap mathematical thinking lebih besar terjadi pada mahasiswa prodi pendidikan matematika. Ini disebabkan, karena kegiatan memecahkan masalah dalam perkuliahan mahasiswa prodi pendidikan matematika lebih sering dilakukan dibandingkan dengan mahasiswa prodi sistem informasi. Hampir 75% mata kuliah yang ada dalam program studi pendidikan matematika melibatkan problem solving dalam tujuan mata kuliahnya, sementara itu, pada program studi sistem informasi, hanya terdapat 10% saja mata kuliah tersebut. Akibatnya mahasiswa pendidikan matematika lebih terlatih kemampuan problem solvingnya dibandingkan dengan mahasiswa prodi sistem informasi.

Development of Students' Pedagogical Abilities through Socio-Psychological Training

“…A certain virtuosity of personality (vivid imagination, the ability to fantasize) is also important for the success of pedagogical activity [36]. As for inborn factors, in some studies, they are considered as anatomical and physiological drives (properties of the nervous system) that underlie the formation of abilities, and the abilities are always the result of progress in a certain activity [37].…”

Pre-Service Mathematics Teachers’ Conception of Higher-Order Thinking Level in Bloom's Taxonomy

“…Delima (2017) reveals there is an influence of problem-solving ability to students mathematical thinking. Furthermore, a good understanding of Bloom Taxonomy will support preservice mathematics teachers in constructing questions to access students' thinking ability.…”

Proses Berpikir Mahasiswa Field Dependent Berdasarkan Kerangka Berpikir Mason

“…Pentingnya pemecahan masalah dalam matematika sehingga menjadi salah satu standar proses menurut NCTM dan pemecahan masalah dapat mengembangkan pemahaman konsep (NCTM, 2000). Soedjadi (Delima, 2017) menyatakan bahwa Indonesia mempunyai dua tujuan utama dalam pendidikan matematika. Pertama, tujuan formil, menekankan pada susunan penalaran dan pengembangan kepribadian anak.…”

“…Pentingnya berpikir matematis yaitu dapat mendukung sains, teknologi, kehidupan ekonomi dan pengembangan dalam perekonomian (Delima, 2017). Oleh karena itu, dalam penelitian ini akan digunakan kerangka berpikir matematis menurut Mason.…”
