Abstract

Matematika adalah salah satu bidang studi yang harus dikuasai oleh siswa, karena merupakan sarana pemecahan masalah sehari-hari. Kesulitan dan kesalahan yang paling banyak dialami siswa dalam menyelesaikan masalah kontekstual adalah rendahnya keterampilan berpikir kritis siswa dalam menyelesaikan pemecahan masalah kontekstual.Tujuan Penelitian ini adalah Untuk mengetahui kesulitan siswa dalam pemahaman mengenai materi bangun Ruang dan untuk mengetahui faktor yang menyebabkan kesulitan belajar matematika pada siswa. Penelitian ini dilaksanakan di SDN 060820 medan. Penelitian ini dilaksanakan pada semester genap tahun ajaran 2022/2023. Penelitian ini merupakan penelitian deskriptif kualitatif yang dilakukan untuk menganalisis dan mendeskripsikan suatu fenomena yang biasanya terjadi di lapangan dengan mempertimbangkan segala masalah yang diteliti. Hasil Penelitian menunjukkan bahwaKesulitan yang dialami siswa pada proses pembelajaran materi bangun ruang khususnya pada topik bola, yaitu: kesulitan pemahaman konsep, kesulitan keterampilan, dan kesulitan pemecahan masalah.

Abstract

Since mastery of problem-solving techniques is one of the main objectives of studying mathematics, such techniques are very important in the field of mathematical education. With the help of the Pythagorean theorem, the problem-solving skills of eighth-grade students will be assessed. SM Muhammadiyah 01 Field, Class VIII-1 Integrated Facilities, is the location of this research. This research uses qualitative research methodology. The instruments used in this study are four and ten-question model questionnaires labeled Highly Agree (SS), Agreed (S), and Disagreement (TS). This research resulted in high categories whose presentation scores reached 57 to 60 were obtained by 2 students, a medium category where its presentation ratings reached 35 to 46 was achieved by 21 students, and a low category where the presentation value reached 2 compared to 31 was achieved by 5 students.

Abstract

The purpose of this study was to test students' ability to solve mathematical problems using Pythagorean theorem material. The subjects of this study were grade VIII students of SMP Ani Idrus perguruan ERIA, a class consisting of twenty children selected using purposive sampling techniques, where six students were selected based on their ability to the instruments in this study, along with supporting instruments such as test instruments for students' mathematical problem-solving abilities and interview procedures. The findings showed that while students in the high-ability category were able to solve problems, they lacked comprehensiveness in reading questions. Advanced students cannot solve a given problem because they can only understand it. Students who are classified as poor in ability are no longer able to answer the challenges given because they continue to struggle to understand the questions given.

Abstract

Finding a solution to a problem is called problem-solving, therefore learning mathematics means finding solutions to problems that arise in everyday life. The purpose of this study is to characterize students' aptitude in mathematical reasoning after completing a project related to Real Analysis. This study used descriptive techniques and was quantitative. Students' logical reasoning skills were revealed from the test results they obtained while answering questions designed based on indicators of mathematical thinking skills. Data analysis techniques used in this research include surveys, data visualization, and observation. Research on students' mathematical thinking skills showed findings with high, medium, and lesser categories.

Abstract

This study aims to describe changes in the mathematical creative thinking abilities of students in the experimental and control classes and to analyze the differences in the increase in mathematical creative thinking abilities between students who received learning with the Problem-Based Learning (PBL) model and students who received conventional learning on the material of comparative value. This research was motivated by the low mathematical creative thinking ability of seventh-grade students of Karya Pembangunan Private Middle School, Deli Tua, especially in the aspect of flexibility and originality. The method used is quantitative with a quasi-experimental design, a nonequivalent control group design type. The study population was all 36 seventh-grade students, with the sample determined through a purposive sampling technique, namely class VII-A as the experimental class (n = 18) who received PBL learning and class VII-B as the control class (n = 18) who received conventional learning. The research instrument is in the form of a descriptive test consisting of 4 questions representing the indicators. Fluency, flexibility, originality, and elaboration were declared valid (0.702–0.721) and reliable (r_hitungCronbach's Alpha= 0.919). The results of the study showed that the average posttest score of the experimental class (12.8333) is higher than that of the control class (9.6667), with the N-Gain of the experimental class being 0.675. The control class was 0.352, both of which are in the medium category, but the magnitude of the increase in the experimental class is consistently higher than the control class. Because the data were not normally distributed (Shapiro-Wilk test, Sig. = 0.008), hypothesis testing used a nonparametric test. Mann-Whitney U test, and the value of Asymp. Sig. (2-tailed) = 0.000 < 0.05 is obtained, so H0 is rejected and Ha is accepted. It can be concluded that there is an influence of the model H_0 H_a Problem-Based Learning on the mathematical creative thinking abilities of class VII students of Karya Pembangunan Private Middle School, Deli Tua, on the material of comparative value.
