Abstract

This research aims to find out the association amongMathematical Critical Thinking (MCT) ability, Mathematical Communication, and Mathematical Curiosity Attitude (MCA) as the impact of applying Problem-Based Learning Cognitive Conflict Strategy(PBLCCS) in Number Theory course. The research method is correlative study. The instruments include a test for mathematical critical thinking skill and communication, and questionnaire to obtain the scores of mathematical curiosity attitude. The findings show that: 1) there is no association between critical thinking skill and mathematical curiosity attitude as the impact of applying problem-based learning cognitive conflict strategy, 2) there is no association between mathematical communication and curiosity attitude as the impact of applying problem-based learning and cognitive conflict strategy, and 3) the impact of applying problem-based learning cognitive conflict strategy is more influential in developing critical thinkingskillthan communication skill and curiosity.

Abstract

This study aims to find out the improvement of students’ mathematical critical thinking viewed from curiosity through teaching materials with Problem Based Learning model. This is quasi-experimental research. The samples are, where the overall population consists of 75 samples divided into two classes.  This research employed a simple random sampling technique.  The instruments were the mathematical critical thinking skill test and curiosity questionnaire. The technique of data collection was carried out with test and non-test techniques. The data were analyzed through a two-way Anova test. Based on the analysis and interpretation of the research findings, it was found that: there was an improvement in students’ mathematical critical thinking skill from High curiosity by using teaching materials with Problem Based Learning model; 1) There was an improvement from  Average curiosity through learning with Integral Calculus teaching materials; 2) There was an improvement from Low curiosity; 3) There was no improvement from the level of curiosity (High,  Medium,  Low) through Problem-based Learning. 4) There was no influence between the level of curiosity and learning in improving students’ mathematical critical thinking skills. Do more in-depth studies related to improving mathematical critical thinking skills by reviewing other affective aspects

Abstract

Penelitian ini bertujuan untuk menggambarkan kemampuan mahasiswa dalam menyelesaikan setiap soal uraian kalkulus integral yang disusun berdasarkan indikator kemampuan berpikir kritis matematis dan berdasarkan level akademik mahasiswa. Bentuk penelitian yang digunakan adalah penelitian kualitatif.  Subyek dalam penelitian ini adalah mahasiswa semester 2 tahun ajaran 2014/2015 Program Studi Pendidikan Matematika FKIP UIR Pekanbaru yang sedang mengikuti mata kuliah kalkulus 2 berjumlah sebanyak 115 orang. Subjek dibagi atas tiga kelompok yaitu mahasiswa pada level kemampuan tinggi (10 orang), mahasiswa pada level kemampuan sedang (88 orang), dan mahasiswa pada level kemampuan rendah (17 orang). Teknik pengumpulan data dalam penelitian ini menggunakan teknik tes dan wawancara. Pengolahan keabsahan data menggunakan teknik triangulasi (mereduksi data, penyajian data, dan penarikan kesimpulan). Berdasarkan hasil penelitian diketahui bahwa: (1) Mahasiswa pada level kemampuan tinggi yang menjawab dengan benar soal pada indikator 1 sebanyak 4 orang (40%), indikator 2 sebanyak 8 orang (80%), dan indikator 3 sebanyak 5 orang (50%); (2) Mahasiswa pada level kemampuan sedang yang menjawab dengan benar soal pada indikator 1 sebanyak 5 orang (5,68%), indikator 2 sebanyak 75 orang (85,23%), dan indikator 3 sebanyak 8 orang (9,09%); (3) Mahasiswa pada level kemampuan rendah yang menjawab dengan benar soal pada indikator 1 sebanyak 0 orang (0%), indikator 2 sebanyak 13 orang (68,42%), indikator 3 sebanyak 5 orang (26,32%); (4) Secara keseluruhan, indikator 1 sebanyak 9 orang (7,69%), indikator 2 sebanyak 96 orang (82,05%), dan indikator 3 sebanyak 18 orang (15,38%). This research aims to describe the ability of students to solve any problem at integral calculus course which is based indicators of mathematical critical thinking ability and  level mathematical ability of students. Research method used in this study is a qualitative research. Subjects in this study were students of the 2nd semester 2014/2015 academic year at Mathematics Education FKIP UIR Pekanbaru. This population of this study were 115 students participating in  integral calculus course. Subjects were divided into three groups: students in high-level abilities (10), students in medium-level (88), and students in low-level (17). Data collection techniques in this study using the test and interview techniques. Processing of data validity using triangulation techniques (data reduction, data presentation, and conclusion). Based on the results of the study are found that: (1) Students at a high-level correctly answering questions on the indicator 1 of 4 students (40%), indicator 2 of 8 students (80%), and 3 indicators as much (50%); (2) Students at the level of ability is being correctly answering questions on the indicator 1 5 students (5.68%), indicator 2 many as 75 students (85.23%), and indicators 3 of 8 persons (9.09%) ; (3) Students at a low level ability correctly answering questions on a first indicator from 0 (0%), indicator 2 as many as 13 students (68.42%), indicator 3 by 5 votes (26.32%); (4) Overall, the indicators one by 9 votes (7.69%), indicator 2 as many as 96 students (82.05%), and a third indicator as many as 18 students (15.38%).
