Analisis Berpikir Kritis Matematis Siswa Ditinjau Dari Big Five Personality

This study aims to describe students' mathematical critical thinking skills with the Big Five personality types, namely Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. This research is a descriptive research with a quantitative approach. Data collection technique used in this research is a Big Five personality type questionnaire and a written test. The research subjects consisted of 10 students who were selected from 29 students with purposive sampling technique. Questionnaire analysis data representing personality types were calculated to determine the dominant personality type in students, after that a mathematical critical thinking ability test was carried out on 10 students to be analyzed as data for classifying students' mathematical critical thinking ability levels analyzed using descriptive analysis. The results obtained are as follows: (1)The critical thinking ability of students with the Openness personality type meets the characteristics of high critical thinking abilities. (2)The critical thinking ability of students with Conscientiousness personality type meets the characteristics of a very high critical thinking ability level. (3)The critical thinking ability of students with Extraversion personality type meets the characteristics of a high level of critical thinking ability. (4)The critical thinking ability of students with Agreeableness personality type meets the characteristics of a high level of critical thinking ability. (5)The critical thinking ability of students with the Neuroticism personality type meets the characteristics of a moderate level of critical thinking ability. (6)The type of personality with the characteristics of very high critical thinking skills in learning mathematics is the Conscientiousness personality typePenelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis matematis siswa dengan tipe kepribadian Big Five yaitu tipe kepribadian Openness,  Conscientiousness, Extraversion,  Agreeableness dan Neuroticism.

Learning Design for Light Wave Oriented to the Multiple-Representations of High School Students in East Aceh

Several studies have shown a deficiency in multiple-representation skills among high school students in East Aceh, where the learning process has not fully accommodated the development of these skills. This research aims to develop a learning design focused on enhancing students' multiple-representation abilities in the subject of light waves. The methods used include surveys and design research, with data collection utilizing validation sheets, pretests, posttests, and interviews. The validation results indicate a very valid category for question instruments, worksheets, and media. An initial survey of 30 high school students in East Aceh revealed an average initial multiple-representation ability of 28.4%. After limited implementation of the learning design, students' multiple-representation ability increased to an average of 61.8%. Thus, this learning design has proven effective in enhancing students' multiple-representation skills. Future research could evaluate its application in other subject materials

KEMAMPUAN KOMUNIKASI MATEMATIS SISWA DAN SELF EFFICACY DENGAN MODEL PEMBELAJARAN BERBASIS E-LEARNING BERBANTUAN MICROSOFT KAIZALA

ABSTRAK Tujuan penelitian ini adalah mendeskripsikan kemampuan komunikasi matematis dan self efficacy siswa pada pembelajaran berbasis e-learning berbantuan Microsoft Kaizala. Jenis penelitian yang digunakan adalah penelitian deskriptif kuantitatif. Subjek pada penelitian ini adalah siswa kelas X OTKP 1 SMK Negeri I Cipanas sebanyak 10 orang siswa. Penelitian ini mengunakan instrumen berupa soal tes dan non tes (kuesioner/angket).  Hasil analisis data menunjukkan bahwa 1) kemampuan komunikasi siswa masuk ke dalam kategori baik; 2) Siswa mampu menyelesaikan permasalahan matematika dengan solusi yang tepat. Namun beberapa responden mengalami kendala dalam merancang permasalahan matematika. Responden tersebut mampu menyelesaikan masalah, namun belum mampu merancang situasi matematika dengan tepat. Siswa harus terbiasa dilatih dalam merancang  permasalahan matematika berdasarkan ide dan keterangan yang dekat dengan kehidupan sehari-hari, kemudian menyelesaikan permasalahan tersebut. 3) Pada tahap pengujian self efficacy, siswa memilki self efficacy cukup tinggi. Pembelajaran berbasis e-learning direkomendasikan menjadi salah satu alternatif metode pembelajaran yang dapat meningkatkan self efficacy siswa

Sifat Preservasi Lingkaran dan Garis Pada Transformasi Möbius

This article discusses Möbius transformation from the point of view of algebra to describe one of its geometric properties, i.e. preserving circles and lines in complex planes. In simple terms, this preservation means that Möbius transformation maps a collection of circles and lines (back) into a collection of circles and lines. In general, the discussion begins with an explanation of the definition of the Möbius transformation in the complex plane. The discussion continues on defining the basic mapping and direct affine transformation. These two concepts are used to prove the existence of the preservation properties of circles and lines in the Möbius transformation. It can be shown that the Möbius transformation can be expressed as a composition of the direct affine transform and the inverse. It can also be shown that the direct affine transform and the inverse both have the property of preserving circles and lines in the complex plane. Thus, it can be concluded that in this study the Möbius transformation has the property of preserving circles and lines in the complex plane

Penerapan Model Guided Discovery Learning Untuk Meningkatkan Pemahaman Konsep Matematis Mahasiswa

This action research is based on the implementation Guided Discovery Learning (GDL) in the 2013 curriculum (K13) for education in Indonesia. Beside that the minimum completeness criteria, for space analytic geometry in Suryakancana University, has not been achieved yet. The aim of this study was to improve the mathematical conceptual understanding of students who were taking lectures on space analytic geometry. The sample consisted of two classes with many students of 19 and 22 respectively. This classroom action research was completed in two cycles. In the second cycle, the class absorption of each class was 78.95% and 77.27%. Thus it can be concluded that the implementation of the GDL model can improve the ability to understand students' mathematical concepts, especially in the analytic geometry of space subject, and in general students provide a positive response to learning with the GDL model
