Abstract

This study aims to analyze the mental structure experienced by students when understanding the concept of probability reviewed from APOS Theory and then suggests a lesson that accommodates the mental structure. APOS theory states that a learner forms a suitable mental structure when interpreting a mathematical concept. This study involved 106 third semester students who enrolled in Probability Theory. The students were given ACE (Activities, Classroom, Exercises) learning cycle treatment. After treatment, students were then given homework assignments that aim to reinforce the learning process. After the sixth week of learning, data were collected through a test. The results of this study are as follows: (1) the mental structure of students towards the concept of opportunity is still at the process level, not at the object-level, (2) Improving the learning of probability concept requires activities to improve verbal understanding, not only in the form of pictures and symbols. The alternative learning treatments are written in this article.

Abstract

This study examines the effect of the flipped classroom learning model and cognitive style on students' mathematical problem solving abilities. The type of quasi-experimental research with the sample technique is cluster random sampling. The population is all students of class XI SMAN 11 Pandeglang, with a sample of 2 classes for 1 experimental class with flipped classroom and 1 control class with conventional. The stages of the research were giving the GEFT test to classify based on cognitive style. Then pretest, treatment and finally given posttest. The test instrument is in the form of 4 essay questions that have been tested using the CVR method. The data analysis technique used was to determine descriptive statistics, pretest and posttest scores, normality and homogeneity tests of N-gain data and Two Way Anova analysis. The results of statistical tests show that 1) there are differences in the improvement of mathematical problem solving abilities of students who use the flipped classroom model with students who use conventional models, 2) there are differences in the improvement of mathematical problem solving abilities between students who have a field independent cognitive style and students who have a cognitive style. field dependent on flipped classroom learning, 3) there is an interaction between the learning model and cognitive style on increasing students' mathematical problem solving abilities.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan dan menganalisis pemecahan masalah matematis siswa di MTs Negeri 3 Serang pada materi sistem persamaan liniar dua variabel (SPLDV) berdasarkan teori Polya ditinjau dari kemampuan representasi matematis. Pemilihan subjek penelitian ini dipilih berdasarkan pada kategori siswa yang menguasai ketiga representasi matematis. Selanjutnya terpilih 3 siswa sebagai subjek dengan kategori memiliki ketiga kemampuan representasi matematik yaitu: representasi visual, representasi simbolik, dan representasi verbal. Penelitian ini menggunakan penelitian deskriptif dengan pendekatan kualitatif. Instrumen yang digunakan untuk pengumpulan data adalah dokumentasi, hasil tes kemampuan pemecahan masalah, dan lembar wawancara. Teknik analisis data yang digunakan adalah reduksi data, penyajian data, dan menarik kesimpulan. Hasil penelitian menunjukkan bahwa subjek penelitian memiliki kemampuan yang berbeda-beda. Semua subjek mampu memahami masalah, merencanakan penyelesaian masalah, dan melaksanakan rencana penyelesaian. Namun kebanyakan masih bermasalah pada tahapan memeriksa kembali jawaban sesuai tahapan Polya. Kata Kunci: Polya, Pemecahan masala, Representasi Matematik

Abstract

Abstract: Emotional intelligence as a spectrum of skills, abilities, and non-cognitive competencies affects the ability of learners to cope with environmental demands and pressures. Self-efficacy is a person's belief about his ability to organize and decide certain actions needed to obtain certain results, and mathematical literacy is the ability used in solving mathematical problems related to everyday life. This study uses a survey-type quantitative approach with a population of 3,737 all State MTs students in Serang Regency. The sampling technique used was area random sampling and 380 respondents were selected. Data analysis techniques include outer and inner models as well as bootstrapping. The results showed that there was a positive and significant effect of emotional intelligence on learning achievement in mathematics, there was a positive and significant effect of emotional intelligence on self-efficacy, there was a positive and significant effect of emotional intelligence on mathematical literacy, there was a positive and significant effect of self-efficacy on learning achievement. mathematics, there is a positive and significant influence of mathematical literacy on learning achievement in mathematics, there is a positive and significant influence on emotional intelligence indirectly through self-efficacy on learning achievement in mathematics, and there is a positive and significant influence on emotional intelligence indirectly through mathematical literacy on learning achievement mathematics.
