Abstract

Mathematical proof is an important aspect in mathematics, especially in analysis. An error in the mathematical proof construction process often occurs. This study aims to analyze the students’ errors in producing proof. Each of the categories of students’ Adversity Quotient (AQ) is identified related to the type of students’ error. The type of students’ errors used according to Newmann’s Error Analysis. This study used a qualitative approach. This study was conducted to 25 students who were taking real analysis course. Documentation, test, and interview were used to gather the data. Analyzing the students’ test result and then interviewing them for each AQ category were done for the analysis process. The results show that there are 48% climber students, 52% camper students, and no one is identified as a quitter student. Climber students tend to make some proving error such as transformation error, process skill error, and encoding error while camper students make the comprehension error, transformation error, process skill error, and encoding error when they are producing proof.

Abstract

This study aims to: (1) describe the implementation of mathematics learning using a cooperative learning model type think pair share to improve understanding of mathematical concept and learning motivation of student, (2) describe the results of an increase in concept understanding and learning motivation of students in class VIII B of SMP Negeri 3 Ponorogo through cooperative learning model type think pair share. This research is a classroom action research (CAR) with data sources include all students of class VIII B consist of 30 students. This  study was conducted in two cycles with each cycle includes four phases: planning, implementation, monitoring/ observation, reflection. The results showed that: (1) the learning process using cooperative learning model TPS in the second cycle has been entered in the excellent category; (2) indicator of the ability to understand mathematical concepts in the second cycle, all indicators have reached very good categories; (3) learning motivation of students in the second cycle reached a score of 67,75% include in the high category. Thus, it can be concluded that the study with cooperative learning model of think pair share the type can improve the understanding of mathematical concepts and motivation of students in class VIII B of SMP Negeri 3 Ponorogo.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh Model Pembelajaran Make A Match dan Talking Stick terhadap kemampuan pemecahan masalah matematika. Juga untuk mengetahui apakah Model Pembelajaran Make A Match lebih efektif terhadap kemampuan pemecahan masalah matematika daripada Talking Stick. Penelitian ini merupakan penelitian eksperimen semu dengan sampel kelas VIII B dan VIII D dari seluruh siswa kelas VIII SMP Negeri 1 Babadan Ponorogo sebagai populasi. Kelas VIII B diberi pembelajaran Make A Match dan kelas VIII D diberi pembelajaran Talking Stick. Data penelitian diperoleh dari hasil tes kemampuan pemecahan masalah matematika yang kemudian dianalisis menggunakan Uji Wilcoxon, Uji Paired Sample t-Test, dan Uji Mann Withney. Diperoleh hasil bahwa Model Pembelajaran Make A Match dan Talking Stick berpengaruh terhadap kemampuan pemecahan masalah matematika. Model Pembelajaran Make A Match lebih efektif terhadap kemampuan pemecahan masalah matematika dibandingkan Talking Stick.

Abstract

Penelitian ini bertujuan untuk menganalisis kesalahan mahasiswa dalam menyelesaikan soal geometri euclide khususnya pada kasus pembuktian. Analisis yang digunakan berdasarkan pada Newmann Error Analysis yang meliputi reading error, comprehension error, transformation error, process skill error dan encoding error. Subyek penelitian ini adalah mahasiswa program studi pendidikan matematika Universitas Muhammadiyah Ponorogo yang sedang menempuh mata kuliah geometri euclide pada semester ganjil tahun akademik 2016/2017. Jenis dan pendekatan dalam penelitian ini yaitu jenis penelitian deskriptif dengan pendekatan kualitatif. Teknik pengumpulan data yang digunakan dalam penelitian ini dengan metode dokumentasi, tes dan wawancara. Analisis dilakukan dengan menganalisis hasil tes kemudian wawancara dengan beberapa mahasiswa dengan tipe kesalahan yang berbeda-beda. Berdasarkan hasil penelitian, diperoleh kesimpulan bahwa kesalahan mahasiswa terletak pada kesalahan teori/konsep dasar serta ketidaklengkapan justifikasi pada setiap langkah yang digunakan dalam pembuktian.This research aim to analyse the student error, when they solve the problems of euclidean geometry especially proofs. That is based on Newmann Error Analysis, such as error reading, error comprehension, error transformation, error skill process and error encoding. This research was conducted toward the student of Mathematic Department, Teacher Training and Education Faculty, Muhammadiyah University of Ponorogo who studied euclidean geometry in 2016/2017. This research was descriptive research with qualitative approach. Documentation method, interview and test was used to gathering data. The analysis process had been doing by analysed the student result test, and then interviewed with some student with different error type. The result of this research was misconception of previous concept and incompletely the justification of every proofs step.
