Abstract

Performa mahasiswa memiliki peran penting dalam menghasilkan lulusan yang berkualitas. Kurang optimalnya performa mahasiswa terlihat dari hasil belajar mahasiswa pada mata kuliah Persamaan Diferensial rata-rata sekitar 70 dan masih ada yang mendapatkan nilai kurang dari 70 sekitar 38%, serta kurangnya kemandirian belajar mahasiswa. Oleh karenanya optimalisasi performa mahasiswa perlu dilakukan. Tujuan dari penelitian ini adalah untuk mendapatkan optimalisasi performa mahasiswa melalui penggunaan bahan ajar komputasi matematika berbantuan software Mathematica. Kemandirian belajar dan hasil belajar mahasiswa dijadikan sebagai sasaran performa mahasiswa yang akan dioptimalkan. Penelitian ini dilaksanakan di Program Studi Pendidikan Matematika FKIP Universitas Muhammadiyah Tangerang yang berjumlah 24 mahasiswa pada mata kuliah Persamaan Diferensial menggunakan bahan ajar Komputasi Matematika Berbantuan Software Mathematica. Penelitian ini merupakan penelitian kuasi eksperimen dengan desain eksperimen yang digunakan adalah one-group pretest-posttest design. Hasil yang didapat dari penelitian ini adalah terdapat perbedaan yang signifikan antara sebelum dan sesudah penggunaan bahan ajar untuk kemandirian belajar dan hasil belajar mahasiswa melalui uji t. Rata-rata peningkatan persentase kemandirian belajar dan hasil belajar mahasiswa secara berturut-turut sebesar 7% dan 24%.Students’ performance has an important role in producing quality graduates. Less optimal students’ performance can be seen from student learning outcomes in Differential Equation courses an average of around 70 and there are still those who score less than 70 about 38%, and lack of students’ self regulated learning. Therefore, optimizing students’ performance needs to be done. The purpose of this study is to obtain the optimization of students’ performance using computational mathematics teaching materials assisted by Mathematica software. Self regulated learning and student learning outcomes are targeted as students’ performance to be optimized. This research was conducted in the Mathematics Education Study Program FKIP Muhammadiyah University of Tangerang, totaling 24 students in the Differential Equation course using Mathematica Software Computational Mathematics teaching material. This research is a quasi-experimental research with the experimental design used is a one-group pretest-posttest design. The results obtained from this study are that there are significant differences between before and after the use of teaching materials for self-regulated learning and student learning outcomes through t-test. The average increase in the percentage of self-regulated learning and student learning outcomes are 7% and 24%, respectively.

Abstract

Most educators agree that problem solving is among the most meaningful and importantkinds of learning and thingking. That is, the central focus of learning and instructionshould be learning to solve problems. There are several warrants supporting that claims.They are authenticity, relevance, problem solving engages deeper learning angtherefore enhances meaning making, and constructed to represent problems (problemsolving) is more meaningful. It is the reason why we must provide teaching and learningto make student’s problem solving skill in progress. There are many informationprocessingmodels of problem solving, such as simplified model of the problem-solvingprocess by Gicks, Polya’s problem solving process etc. One of them is IDEAL problemsolving. Each letter of IDEAL is stand for an aspect of thinking that is important forproblem solving. IDEAL is identify problem, Define Goal, Explore possible strategies,Anticipate outcme and Act, and Look back and learn. Using peer interaction andquestion prompt in small group in IDEAL problem solving teaching and Learning canimprove problem solving skill.Kata kunci: IDEAL Problem Solving, Interaksi Sebaya, Pertanyaan Penuntun, KelompokKecil.

Abstract

Jenis penelitian ini adalah deskriptif kualitatif yang bertujuan untuk mengetahui bagaimana profil berpikir geometri siswa tunagrahita berdasarkan tingkatan berpikir van Hiele. Subjek dalam penelitian ini adalah tiga orang siswa yang terdiri masing-masing satu siswa dari kelas VII, VIII dan IX SMPLB C Negeri Salatiga. Penelitian ini dilakukan melalui wawancara semi terstrukur. Hasil dari penelitian yang dilakukan, ketiga siswa cenderung memiliki kemampuan yang sama dalam berpikir geometri. Ketiga siswa dapat mencapai tingkat 1 (visualisasi) berdasarkan tingkat berpikir geometri van Hiele, namun terbatas pada bentuk-bentuk bangun geometri yang dipahami atau dikenalnya. Siswa belum dapat melakukan analisis pada tingkat 2 dan hanya sebatas mengetahui sebagian komponen pada bangun segiempat serta menamainya menggunakan bahasanya sendiri yang tidak baku. Selain itu siswa mengetahui beberapa istilah yang ada pada bangun segiempat, namun tidak mengetahui maksud dari istilah-istilah tersebut. Kendala dan masalah yang dihadapi ketiga siswa yaitu lebih cenderung memperhatikan pada bangun-bangun yang dikenalnya, kurang cermat dan teliti dalam menggambar, kesulitan dalam menjelaskan atau mendeskripsikan secara lisan suatu bangun segiempat dan hanya terbatas pada bangun yang diketahuinya, hal tesebut karena siswa tidak banyak mengenal macam-macam bangun.This research is a qualitative descriptive which aims to determine how the profile geometry students think retarded by van Hiele levels of thinking. Subjects in this study were three students who comprised each of the students of class VII, VIII and IX SMPLB C State Salatiga. This research was conducted through semi-structured interviews. The results of the research conducted, the three students tend to have the same ability to think geometry. All three students can reach level 1 (visualization) based on the geometry of the van Hiele levels of thinking, but limited to the forms of geometry understood or known. Students have not been able to perform the analysis at 2 and merely knowing some components in the wake of the quadrilateral and named him use his own language is not standardized. In addition, students know some of the terms that exist in the wake of the quadrilateral, but do not know the purpose of these terms. Constraints and problems faced by the three students are more likely to pay attention in the wake familiar, less meticulous in drawing, difficulty in explaining or describing verbally a wake quadrilateral and confined to the waking knew, tesebut because students do not know a lot of Miscellaneous wake.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kesulitan belajar yang dialami mahasiswa pada materi aplikasi integral untuk luas daerah dalam perspektif disposisi matematis. Penelitian ini menggunakan metode deskriptif eksploratif dengan instrumen skala, tes, dokumentasi, dan catatan lapangan. Data diambil dari 80 mahasiswa dari program studi S1 pendidikan matematika di sebuah universitas di Jawa Tengah. Hasil penelitian menunjukkan bahwa mahasiswa dengan disposisi matematis positif sedang dan tinggi memiliki jenis kesulitan yang sama yaitu (1) kesulitan dalam menggambar grafik, (2) kesulitan dalam menentukan daerah yang dicari luasnya, (3) kesulitan dalam menentukan batas integral, (4) kesulitan dalam menggunakan rumus integral, dan (5) kesulitan dalam memahami integral. Mahasiswa dengan disposisi matematis positif rendah selain mengalami kelima kesulitan tersebut, juga mengalami kesulitan dalam menghitung integral. Terdapat tren atau kecenderungan peningkatan persentase pada 2 jenis kesulitan, dan penurunan persentase pada 1 jenis kesulitan, sedangkan pada 3 jenis kesulitan yang lain bersifat fluktuatif.The purpose of this research was to described the learning difficulties experienced by students in integral application material for the area in the perspective of mathematical dispositions. This research used descriptive exploratory methods with scale, tests, documentation, and field notes instruments. Data was taken from 80 undergraduate students from the mathematics education study program at a university in Central Java. The results showed that students with moderate and high positive mathematical dispositions had the same types of difficulties, namely (1) difficulties in drawing graphics, (2) difficulties in determining the area to be searched for, (3) difficulties in determining integral boundaries, (4) difficulties in using integral formulas, and (5) difficulties in understanding integrals. Students with low positive mathematical dispositions in addition to experienced these five difficulties, also experienced difficulties in calculating integrals. There is a trend or tendency to increase percentage in 2 types of difficulties, and a decrease in percentage in 1 type of difficulty, while in 3 other types fluctuating.
