Abstract

The purpose of this study was to see the improvement of students' mathematical problem-solving ability after implementing of the Creative Problem Solving (CPS) learning model. The research method used quantitative research with a quasi-experimental design. The population of this study was all students of class VIII of SMP PGRI 5 Cimahi. Two classes as research samples were selected through the Cluster Random Sampling technique, where one class was the experimental class and one class was the control class. The instrument used was a mathematical problem-solving ability test instrument in the form of a description of 5 questions arranged based on indicators of mathematical problem-solving ability. Data processing used the normality test and the Mann-Whitney test. The results of this study were an increase in students' mathematical problem-solving ability who implemented the Creative Problem Solving (CPS) learning model better than those who used conventional learning.

Abstract

The ability to solve problems is an essential skill that students must have in everyday life and as an integral part of the math curriculum. The research aims to achieve and improve the mathematical problem-solving ability of junior high school students through the application of the STAD (Student Teams Achievement Divisions) cooperative learning model. The method used is a quasi-experimental design experiment. The results of the study found that before the implementation of the STAD model, students' mathematical problem-solving skills were still low, as seen from the results of the pre-test. This study concluded that cooperative learning STAD is effective in achieving and improving the mathematical problem-solving ability of junior high school students.

Abstract

This research aims to see the improvement in mathematical problem solving abilities of class VII middle school students through the Discovery Learning Learning Model assisted by animated videos. This research is experimental research.   The population in this study were class VII students, while the sample was students from class VII A as the experimental class and VII B as the control class at SMP IT Al-ajwa Al-Islamy. This research uses the Nonequivalent Pretest-Posttest Control Group Design research design. The research instrument used was an essay question with a total of 7 questions.  The data obtained will be analyzed and processed using a 2 independent sample test using a normality test, a homogeneity test first as a prerequisite and followed by a t-test.  The results of hypothesis testing using the Independent Sample T-Test show that the significant value is 0.000 ≤ 0.05, so is rejected.  So, it can be concluded that the Discovery Learning Model assisted by animated videos to improve the mathematical problem solving abilities of Al-Ajwa Al-Islamy IT Middle School students is better and has increased.

Abstract

This research aims to analyze the increase in students' critical mathematical thinking skills after being given treatment using the approach problem solving. This research was carried out at SMP Negeri 36 Bandung in class VIII with a sample size of 25 students. The method used in this research is quasi-experimental. The instrument and learning tools used are questions pretest and questions posttest. The data collection technique in this research is 5 descriptive questions with indicators of critical thinking abilities. Data analysis was carried out using the N-Gain test, normality test, test Mann-Whitney, homogeneity test, and Test independent t-test. The results of the research showed that there was an increase in students' mathematical critical thinking abilities by learning using problem solving approach.

Abstract

The motivation behind this investigation was the weak performance of children in math problems. The purpose of this study is to determine the impact of problem-based learning model on improving students' ability to solve mathematical problems. This study utilized a quasi-experiment method with a Nonequivalent Control Group design. The subjects in this study were class VII B as the experimental group and class VII C as the control group. Each of the two classes had thirty-five students.  The purpose of using a control group as a comparison is to observe what symptoms appear in the group of participants who receive treatment. The conclusion shows that the Problem Based Learning model has a significant impact on the average N-Gain score based on the variation between the pretest score and the final score, namely the posttest score, where the average N-Gain score of the experimental and control classes is significantly different.

Abstract

This research was motivated by the low mathematical communication skills of high school students, this research was carried out at SMP Dharma Kartini in grade VII as many students. The instrument used was a mathematical communication ability description test. The purpose of this research is to improve students' mathematical communication skills and the achievement of students' learning goals using the Problem Based Learning (PBL) model assisted by audiovisual media. The data from the study were processed using 2 independent samples using the normality test and the Monte Carlo test. The results of the analysis showed that grade VII junior high school students who used the Problem Based Learning (PBL) model with the help of audiovisual media got a better increase in mathematical communication skills compared to students who used the conventional learning model. Furthermore, students who get an improvement in learning using the Problem Based Learning (PBL) model assisted by audiovisual media also experience achievement in learning objectives.

Abstract

The aim of this study is to evaluate the enhancement of mathematical problem-solving abilities among Grade VII Junior High School students using two different instructional models: the Visual Basic for Applications Excel (VBA) Assisted Problem-Based Learning Model and the scientific learning model. The research employs an experimental approach with a pretest-posttest control group design involving two groups: an experimental class and a control class. The entire 7th-grade population of SMP Negeri 3 Lembang participated in the study, with Class VII-D serving as the experimental group and Class VII-E as the control group. Data on mathematical problem-solving abilities were collected through pretest and posttest assessments. Data analysis was conducted using Microsoft Excel and SPSS 29. The findings indicate that students in the experimental group, who were taught using the Problem-Based Learning Model assisted by Visual Basic for Applications Excel (VBA), demonstrated greater improvement in their mathematical problem-solving skills compared to those taught using the scientific learning model.

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan pemahamn konsep matematis siswa setelah mengikuti pembelajaran dengan pendekatan saintifik pada materi aljabar. Penelitian dilakukan di SMP Pondok Pesantren Baitul’Izzah Nusantara pada kelas VII yang terdiri dari 20 siswa. Instrumen yang digunakan meliputi soal pretest dan posttest serta Lembar Kerja Peserta Didik (LKPD) yang berisi materi aljabar. Data yang terkumpul akan dianalisis menggunakan analisis 2 sampel dependent, dimulai dengan uji normalitas untuk memastikan distribusi data, dan dilanjutkan dengan uji homogenitas serta uji t-test untuk menilai signifikansi perbedaan antara nilai pretest dan postest. Hasil analisis menunjukkan adanya peningkatan yang signifikan dalam kemampuan pemahaman konsep matematis siswa setelah pembelajaran menggunakan pendekatan saintifik. Temuan ini memberikan dukungan bahwa pendekatan ini efektif dalam meningkatkan kemampuan siswa dalam pemahaman konsep matematis, khususnya dalam konteks materi aljabar.
