Abstract

In learning mathematics, students often experience mistakes or omissions in solving the questions given both the questions of practice, assignments, tests, and exams. This study aims to determine the student's errors mistakes in solving mathematical problems in the composition and inverse functions in SMA Negeri 1 Maumere. The method used is descriptive qualitative, with X MIPA 4 students' research subjects, amounting to 34 people who were selected based on purposive sampling technique where this subject who gets material on compulsory mathematics, namely the material composition function and inverse function. Data collection procedures are taken through the provision of test questions and interviews whit students. Data analysis includes data reduction, data presentation, and conclusions. This study results can be said that the student's errors in solving mathematical problems in the composition and inverse functions of high, medium, and low ability students make the same mistakes, namely errors in using data, language interpretation errors, and technical errors.

The validity of the data used triangulation method. The results of this study show that male and female students who have high learning interest have the ability to understand the concept that being able to explain, to apply the relationship between concepts and procedures, and provide examples and not examples, but they are unable to develop concepts. Male students who have medium learning interest are able to explain and give examples and not examples, but are less able to apply the relationship between concepts and procedures and also unable to develop concepts. Female students who have medium learning interest are able to explain, to apply relationship between concepts and procedures, and to provide examples and not examples, but they are unable to explain and to develop concepts. Male students who have low learning interest are able to apply the relationship between concepts and procedures and to provide examples and not examples, but they are unable to explain and to develop concepts. Female students who have a low interest learning are unable to explain, unable to apply the relationship between concepts and procedures, unable to provide examples and not examples, and unable to develop concepts that have been learned.

Abstract

ABSTRAK: Penelitian ini bertujuan untuk meningkatkan kualitas proses dan hasil belajar Statistika Dasar mahasiswa Jurusan Pendidikan Matematika FKIP Unismuh Makassar melalui penerapan Model Pembelajaran Kooperatif Tipe Snowball Throwing. Jenis penelitian ini merupakan Penelitian Tindakan Kelas (PTK). Subjek penelitian ini adalah mahasiswa IC sebanyak 32 orang terdiri dari 3 laki-laki dan 29 perempuan. Penelitian ini dilaksanakan selama 2 siklus. Setiap siklus terdiri atas 8 tahap, tahap (1) guru/dosen menyampaikan materi yang akan disajikan, (2) guru/dosen membentuk kelompok–kelompok dan memanggil masing–masing ketua kelompok untuk memberikan penjelasan tentang materi, (3) masing-masing ketua kelompok kembali ke kelompoknya kemudian menjelaskan materi yang disampaikan oleh guru/dosen kepada teman-temannya, (4) kemudian masing-masing peserta didik diberikan satu lembar kertas kerja untuk menuliskan satu pertanyaan apa saja yang menyangkut materi yang sudah dijelaskan oleh ketua kelompok, (5) kemudian kertas tersebut dibuat seperti bola dan dilempar dari satu peserta didik kepeserta didik yang lain selama lebih dari 15 menit, (6) setelah peserta didik dapat satu bola diberikan kesempatan kepada siswa untuk menjawab pertanyaan yang tertulis dalam kertas berbentuk bola tersebut secara bergantian, (7) evaluasi untuk materi yang telah dibahas, dan (8) penutup. Hasil tes menunjukkan dari 32 mahasiswa, pada siklus I hanya 11 Mahasiswa (34,37%) yang mencapai skor standar ketuntasan yakni 75. Pada siklus II mengalami peningkatan menjadi 28 mahasiswa (87,50%). Berdasarkan observasi mahasiswa merasa tertarik dengan aktif dan bersunggu-sunggu dalam mengikuti perkuliahan, selain itu kerjasama dan saling menghargai antara mahasiswa juga nampak terjadi. Dari hasil wawancara dengan mahasiswa yang diajar merasa senang dengan model yang digunakan tersebut. KATA KUNCI: Hasil belajar, model pembelajaran kooperatif tipe snowball throwing

Abstract

The purpose of this study was to know the effect of Blended Learning on the ability of Mathematical Representattion and Self efficacy. Populations of this study were all students of class VIII in one of SMP in Purwokerto at 2018. It was experimental study post test only disgn. The sampel were students of class VIII G as the experimental class and class VIII D as the control class. The average of post test result of the students’ mathematical representation ability reach 70,30 for the experimental class and 62,08 for the control class. After a hypothesis testing by using Man Whitney test was obtained significance value of 0,036. Due to the significance value was smaller, so H0 was rejected. It can be concluded that the mathematical representation of students using blended learning was higher than students using direct learning or the blended learning has an effect on mathematical representation.The average of questionnaireof result of the students’ efficacy ability reach 77,05 for the experimental class and 74,91 for the control class. After a hypothesis testing by using Man Whitney test was obtained significance value of 0,254. Due to the significance value was bigger, so H0 was accepted. It can be concluded that there was no difference between the students’ self efficacy by blended learning and direct learning or the blended learning has no effect on student’ efficacy.

Abstract

The purpose of this study is to find out which gives better mathematics learning achievement in the TPS type cooperative learning model with a scientific approach, students with high, medium, or low levels of social interaction on the subject matter of function. This research is a quasi-experimental study. The population is all eighth grade students of state junior high schools in Ngawi Regency 2016/2017 school year. The sampling technique uses stratified cluster random sampling, so that students are obtained at SMP Ngrambe 3, SMP Negeri 2 Paron, and SMP Negeri 2 Widodaren as a research sample of 90 students. Data collection instruments used achievement tests and student social interaction questionnaires. Hypothesis testing using analysis of variance (anava) one cell path is not the same. The conclusion of this study is the type of TPS cooperative learning model with a scientific approach to students with high levels of social interaction provides better mathematics learning achievement compared to students with moderate and low levels of social interaction, and mathematics learning achievement of students with moderate levels of social interaction as well compared to students with levels of interaction socially low in providing mathematics learning achievement on the subject matter of function.
