Abstract

This study aims to analyze students’ mathematical conceptual understanding ability based on their adversity quotient. The indicators of mathematical conceptual understanding in this study are (1) to restate a concept, (2) classifying objects by their properties, (3) giving an examples and counter examples, (4) presenting concepts into various mathematical representation, (5) to use and choose the procedure properly, (6) applying a concept or algorithm in problem solving and (7) to develop the sufficient requirements of a concept. There are three types of adversity quotients in this study are quitter, camper, and climber. This is a descriptive qualitative research. The Subjects in this study were 106 people of natural science major, in second grade of high school in Jakarta. The instrument used was the test of mathematical conseptual understanding ability and adversity quotient questionaire. Data were analyzed by reducing data, presenting the data and making the conclusions. Based on the study, there are two students with quitter types, 60 students with camper types, and 44 students with climber types. This Research indicates that the mathematical conceptual understanding ability is moderate category and the type of students’ adversity quotient is classified as camper.

Abstract

The covid-19 pandemic period like now requires to find an alternative learning that is effectively used. It drives a changing method of learning from face-to-face to online. One alternative in learning today is the use of smartphones or commonly referred to as mobile learning. This study aims to determine: 1) differences in student mathematics learning achievement with learning through mobile learning and google classroom, 2) interaction between learning through mobile learning and the ability to work together with students towards mathematics learning achievement, 3) differences in student mathematics learning achievement at the level of ability cooperate. The subjects of this study were students of the Mathematics Education Study Program STKIP Pamane Talino who took 68 Integral Calculus courses consisting of 2 classes. The research was conducted in 5 meetings. Each group was taught with the same material. The instruments in this study were test and questionnaire. The research method used was quasi experiment with 2x3 factorial design approach. The data analysis test used was the two-way ANAVA test with the analysis prerequisites in the form of a normality test and a homogeneity test. The results of data analysis show that the data are normally distributed and homogeneous. Thus, it can be concluded that: (1) learning with Mobile Learning media is more effective than learning with Google Classroom media, (2) the level of ability to work together high, medium and low gives different effects on student mathematics learning achievements and (3) students with all levels of ability to work with learning media Mobile Learning and Google Classroom provide equally good learning achievements.

Abstract

Pembelajaran Matematika di jenjang Sekolah Menengah Kejuruan (SMK) masih memerlukan pilihan model pembelajaraan kooperatif yang dapat mengoptimalkan prestasi belajar. Hal ini dikarenakan lulusan SMK harus mampu bersaing di bidang teknologi. Model pembelajaran kooperatif tipe Teams-Games-Tournaments (TGT) dipilih, sebab model tersebut dapat meningkatkan rasa kebersamaan dan saling menghargai sesama anggota kelompok sehingga memunculkan motivasi belajar siswa. Tujuan penelitin ini adalah untuk mengetahui prestasi belajar siswa berdasarkan tiga tingkatan motivasi belajar dan dua tipe model pembelajaran kooperatif, yaitu tipe TGT dan tipe Jigsaw, pada pokok bahasan Persamaan Lingkaran. Metode penelitian yang digunakan adalah metode kuantitatif dengan desain quasi eksperimental dan rancangan faktorial 2x3. Populasi penelitian ini adalah semua siswa kelas XI SMK Gondang Wonopringgo yang terdiri dari 10 kelas. Teknik pengambilan data yang digunakan adalah tes dan angket. Teknik analisis data dilakukan dengan menggunakan Anava dua jalan. Hasil penelitian menunjukkan bahwa: (1) Prestasi belajar siswa pada pembelajaran dengan model kooperatif tipe TGT lebih baik daripada pembelajaran dengan model kooperatif tipe Jigsaw; (2) Prestasi belajar siswa yang memiliki motivasi belajar tinggi lebih baik dari pada siswa yang memiliki motivasi belajar sedang dan prestasi belajar siswa yang memiliki motivasi belajar sedang sama baiknya dengan siswa yang memiliki motivasi belajar rendah; (3) Tidak terdapat interaksi yang signifikan antara tiga tingkatan motivasi belajar dengan dua tipe model pembelajaran kooperatif, yaitu tipe TGT dan tipe Jigsaw, ditinjau dari prestrasi belajar.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pemecahan masalah Higher Order Thinking yang ditinjau dari gaya kognitif siswa. Penelitian ini merupakan penelitian kualitatif. Peneliti menggunakan data hasil GEFT (Group Embedded Figure Test), data hasil penyelesaian soal – soal berpikir tingkat tinggi (Higher Order Thinking) dan juga data hasil wawancara pada dua subjek siswa SMA Negeri 1 Taman. Dua subjek tersebut terdiri dari satu subjek dengan gaya kognitif field independent dan juga satu subjek dengan gaya kognitif field dependent. Selanjutnya data yang diperoleh dianalisis dengan menggunakan empat indikator pemecahan masalah Polya. Dari penelitian yang telah dilakukan menujukkan hasil penelitian sebagai berikut: (1) Siswa dengan gaya kognitif field independent dinyatakan mampu pada seluruh indikator pemecahan masalah Polya pada masalah matematika higher order thinking dengan tingkatan kognitif analyze (menganalisis), evaluate (mengevaluasi) dan create (menciptakan). (2) Siswa dengan gaya kognitif field dependent dinyatakan mampu pada seluruh indikator pemecahan masalah Polya pada masalah matematika higher order thinking dengan tingkatan kognitif analyze (menganalisis) dan create (menciptakan). Akan tetapi kurang mampu pada indikator merencanakan atau merancang strategi pemecahan masalah, indikator melaksanakan perhitungan serta indikator memeriksa kembali kebenaran hasil atau solusi pada tingkatan kognitif evaluate (mengevaluasi).

Abstract

Mathematics Education of UIN Raden Intan Lampung has a problem in the process of preparing the thesis proposal seminar schedule, because there are many students who conduct seminars in the adjacent period. During this time the preparation of the proposal seminar schedule is done manually, not infrequently many schedule lecturers and examiners are clashing with other student proposal seminar schedules. To overcome these problems, a thesis proposal seminar schedule was arranged by applying the concept of point coloring to graphs using the Welch Powell Algorithm. The points on the graph are represented as students who will conduct a thesis proposal seminar, while the side that connects the two points states that these two points have one and / or two supervisors. The research method used is the study method of literature study. The results of this study indicate that graph coloring using Welch Powell algorithm can be applied to arrange seminar schedule for students' thesis proposal for Mathematics Education, Faculty of Tarbiyah and Teacher Training. UIN Raden Intan Lampung.
