Profil Kemampuan Penalaran Kreatif Matematis Mahasiswa Calon Guru

This study aims to obtain an overview of the mathematical creative reasoning abilities of the prospective teacher. The ability of mathematical creative reasoning in this study is the ability of students to justify a statement on the grounds of the truth of a statement that is based on novelty, plausible, and mathematical foundation. This research approach is qualitative using Grounded Theory. The population in this study were all students participating in the Calculus class of the Study Program Mathematics Education at one of the universities in West Java. In a while, the sample of 55 students was selected by a cluster random sampling technique. The results showed that students' mathematical creative reasoning abilities were categorized into three levels of ability based on the quality of the four categories, namely the initial step, the flow of completion, the related concepts, and the mathematical term errors

KEMAMPUAN PEMAHAMAN MATEMATIS SISWA PASCA PANDEMI COVID-19 PADA MATERI PERSAMAAN KUADRAT KELAS IX

Students must have the ability to understand mathematics because learning mathematics is not only about memorizing formulas and counting, but also about understanding concepts. The purpose of this study is to determine the mathematical understanding of students after the Covid-19 pandemic with quadratic equations. This type of research is qualitative with a population of 30 students and a sample of 10 class IX students conducted at SMPN 8 Cimahi. The instrument used is a mathematical comprehension test. The data obtained from the test results are processed in three stages, namely first data reduction (analysis of student answers), second presentation, and thirdly drawing researchers' conclusions. The results showed that 10% of students who have mathematical ability belong to the very high and very low categories, 20% belong to the high and low categories, and 40% of students belong to the medium category. This research shows that students' mathematical comprehension skills still need to be developed because students still do not understand the material and are not used to doing mathematical comprehension questions so they still make mistakes when solving problems

HUBUNGAN KEMAMPUAN KOMUNIKASI MATEMATIK SISWA SMP DI KABUPATEN BANDUNG BARAT MENGENAI MATERI PERSAMAAN DAN PERTIDAKSAMAAN LINEAR SATU VARIABEL

This study aims to describe the mathematical communication skills of seventh grade students of West Bandung District Junior High School in understanding linear equations and one variable inequality. This type of research is qualitative research. Research subjects were selected based on even semester semester math report cards. Research subjects used in this study were 3 students selected from 15 students, namely one high-ability student, one moderate-capable student and one low-ability student. The results of this study were (1) Subjects with high ability in understanding Equation and the inequality of one variable reaches three indicators of mathematical communication ability that is to state mathematical problems related to Linear Inequality and Inequality One variable in the form of a story problem. stating the problem given in the form of mathematical models in the form of equations and solving them and stating a story problem into an idea or problem related to Equality and Inequality of one variable and can solve the problem, (2) Subjects with moderate ability to understand Equations and Inequality One variable reaches two indicators of mathematical communication ability, namely expressing mathematical problems related to equations and inequality of one variable in the form of story problems and expressing an image into an idea or mathematical problem related to linear equations and inequalities of one variable and the problem can be solved. And (3) Subjects with low ability in understanding Equations and inequality of one variable reach an indicator of mathematical communication ability which states mathematical problems related to linear equations and inequalities of one variable

Pengembangan model PJBL berbantuan tableau pada mata kuliah statistika dasar untuk meningkatkan kemampuan analisis statistik mahasiswa

The ability of student teacher candidates is still low, one of which is understanding of statistical analysis. The purpose of this study was to develop a Tableau-assisted PJBL learning model to improve students' statistical analysis skills in basic statistics courses. This type of research is development (R&D) according to Thiagarajan's flow, namely 4-D (Four-D Models) with 36 students who teach basic statistics courses as many subjects.

PELATIHAN SOFTWARE WINGEOM UNTUK MENINGKATKAN KOMPETENSI GURU DI KECAMATAN PANGALENGAN

Community service is conducted in the form of a training workshop on the use of wingeom software for elementary, junior and senior high school teachers in Pangalengan District. The purpose of this service is to improve teacher competence in using learning software in the classroom, especially wingeom software. The location of the service was held at SMAN 1 Pangalengan, with a total of 51 participants. Researchers conducted initial observations by distributing questionnaires on the google form. The results of preliminary observations indicate that teachers in schools are still lacking in the use of ICT, especially mathematical software in learning. The teachers do not have the skills to use the software in learning mathematics. The lack of use of ICT is due to the teachers' lack of understanding of ICT, so that teachers have difficulty in operating mathematical software. This has encouraged the implementation team to conduct wingeom software training to improve the competence of teachers in the ICT field in Pangalengan District. During the wingeom software training, the teachers were very enthusiastic in following their activities from the beginning to the end of the training. Through the questionnaire at the end of the training it was found that the teachers could master the wingeom software and be able to apply the software when learning especially learning about geometry. Wingeom software training can improve the competence of teachers in Pangalengan District. Through this mathematics software training, the teacher has skills n teaching mathematics that is interesting and fun for students
