Abstract

The students’ mathematical literacy is a students’ skill in mathematics that become the initial support to enhance several potential cognitive skill i.e. analysis, synthesis, evaluation and students’ decision making in mathematics. The purpose of this study was to identify mathematical literacy aspects that develops in the students’ problem solving process. Participants of this study were 50 students in Calculus class at Universitas Serang Raya. The mathematical literacy aspects used is the relationship between the mathematical process (3 categories) and the basic mathematics skill (7 categories). The identification of a number variables of mathematical literacy that developed in the students’ problem solving process traced by confirmatory factor analysis. The analytical procedure obtained that three factors of mathematical literacy that supported the development of students’ problem solving work namely reasoning, devising strategies and mathematising. The dominant factor that provides a huge impact is the reasoning with the diversity data fairly accurate 74,31%. These results can be taken into consideration in preparing instructional and evaluations materials particularly in Calculus and as a reference analysis as well to similar aspects for other sciences course.Keywords: Confirmatory Factor, Factor Analysis, Mathematical Literacy, Problem Solving

Abstract

[Bahasa]: Penelitian ini bertujuan untuk menguji apakah ada perbedaan peningkatan kemampuan pemecahan masalah antara mahasiswa yang mendapat pembelajaran dengan pendekatan keterampilan fungsional matematis dan pembelajaran konvensional. Pendekatan penelitian kuantitatif dengan desain kuasi eksperimen digunakan untuk mencapai tujuan tersebut. Mahasiswa semester dua yang mengambil mata kuliah Kalkulus II pada jurusan pendidikan Matematika, Universitas Serang Raya dijadikan sebagai populasi penelitian. Sebanyak dua kelas ditentukan secara purposive random sampling untuk sampel penelitian, selanjutnya dinamakan kelas eksperimen dan kelas kontrol. Kelas eksperimen yaitu kelas yang mendapat pembelajaran dengan pendekatan functional skills mathematics sementara kelas kontrol adalah kelas yang mendapat pembelajaran konvensional. Hasil uji statistik menunjukkan bahwa tidak terdapat perbedaan rata-rata capaian namun terdapat perbedaan peningkatan (N-Gain) kemampuan pemecahan masalah di kedua kelas. Hal ini menunjukkan bahwa kemampuan pemecahan masalah mahasiswa di kelas eksperimen cenderung meningkat. Kata kunci: Keterampilan Funsional Matematis; Pemecahan Masalah; Quasi Eksperimen [English]: This study aims to examine whether there are differences in improvement of problem-solving ability between students who received learning with the approach of functional skills mathematics and conventional learning. Quantitative research with quasi experiment is used to achieve that goal. The second semester student who enrolled on Calculus II in the Mathematics Education Department, Universitas Serang Raya were the population of research. Two classes were determined by purposive random sampling for the sample of research, called experimental class and control class. The experimental class was taught using functional skills mathematics while the control class was taught by the conventional learning. The results of the statistical tests show that there is no difference in average performance but there is difference in N-Gain problem solving skills in both classes. This research concludes that problem-solving ability of students in the experimental class tends to increase. Keywords: Functional Skills Mathematics; Problem Solving; Quasi Experiment
