Abstract

This study aims to examine the impact of Project-Based Learning (PjBL) on the problem-solving abilities of tenth-grade students at SMA Negeri 1 Pegajahan within the context of the Merdeka Curriculum. The research employs a quantitative method with a quasi-experimental approach, utilizing a Pretest-Posttest Only One Group Design. The population includes all tenth-grade students, with samples selected using Cluster Random Sampling techniques. Data were collected through pretests and posttests and analyzed using descriptive and inferential statistical tests, including normality tests, homogeneity tests, and the Paired Sample t-Test. The results indicate a significant improvement in students' problem-solving abilities following the implementation of PjBL. The t-test results demonstrate a positive effect of PjBL on students' problem-solving skills. Based on these findings, it is concluded that PjBL is an effective teaching method for enhancing students' mathematical problem-solving abilities. This study provides valuable contributions to the development of more innovative and relevant teaching methods, particularly in supporting the implementation of the Merdeka Curriculum in Indonesia.

Abstract

Male students are different from women in acquiring, understanding and mastering mathematical concepts. This study intends to describe the ability of students to understand mathematical concepts from a gender perspective. The ability to understand mathematical concepts is analyzed from problem solving. This study applies a qualitative descriptive method. The subjects of the study were male and female students in grade IX of the Medan National Hero Private Junior High School as many as 12 people each. The research instrument used was in the form of a written test of mathematical concept comprehension ability consisting of 3 valid essay questions and an interview. The data was analyzed based on gender indicators of mathematical concept comprehension ability, namely restating concepts that have been learned, using certain procedures or operations, and applying concepts in meaningful problem solving to the concepts studied. Data are compared by gender. The results of the study showed that the ability to understand mathematical concepts of female students was better than that of male students on the indicators of restating the concepts that had been learned, using certain procedures or operations and applying concepts in meaningful problem solving to the concepts studied, which can be seen from the average achievement of female students 72.183 while male students reached an average of 58.3.

Abstract

Sosial media telah menjadi bagian integral dalam kehidupan sehari-hari masyarakat modern. Di desa Aman Damai, Kec. Seirapit, Kabupaten Langkat, penggunaan sosial media telah berkembang pesat dalam beberapa tahun terakhir. Namun, dengan pertumbuhan tersebut, muncul pula tantangan dalam penggunaan yang baik dan benar dari platform-platform sosial media. Penelitian ini bertujuan untuk mengkaji upaya sosialisasi penggunaan sosial media yang baik dan benar kepada warga di desa Aman Damai. Hasil sosialisasi yang dilakukan oleh pemerintah setempat dan organisasi masyarakat telah memberikan dampak positif dalam meningkatkan pemahaman warga tentang pentingnya penggunaan sosial media yang baik dan benar. Namun, masih ada kebutuhan untuk meningkatkan edukasi dan kesadaran warga mengenai bahaya penyebaran informasi palsu (hoaks), pelecehan online, serta privasi data. Dalam rangka menciptakan lingkungan sosial media yang lebih sehat dan beretika di desa Aman Damai, disarankan agar pemerintah setempat dan berbagai pihak terkait terus aktif dalam melaksanakan sosialisasi dan pelatihan terkait penggunaan sosial media. Selain itu, kolaborasi antara pemerintah, sekolah, dan organisasi masyarakat dapat menjadi langkah strategis untuk menciptakan pemahaman yang lebih baik tentang penggunaan sosial media yang bertanggung jawab dan positif di tengah masyarakat.

Abstract

This research aims to investigate the impact of the project-based learning model on students' problem-solving abilities. The study employed a quantitative research methodology with a quasi-experimental design. Specifically, a pretest-posttest control group approach was used. The population under investigation consisted of all students in the Mathematics Education study program at the Faculty of Tarbiyah and Teacher Training (FITK), UIN North Sumatra Medan. The sampling technique employed cluster random sampling, resulting in 26 students from the PMM-2 class being selected as the experimental group, while 27 students from the PMM-1 class served as the control group. Data collection involved a problem-solving ability test in descriptive form. For hypothesis testing, the independent sample t-test was utilized, preceded by tests to assess normality and homogeneity. The analysis of post-test data revealed a significance value of 0.0000 < ???? = 0.05, leading to the rejection of the null hypothesis (Ho) and acceptance of the alternative hypothesis (Ha). This finding indicates a significant difference in problem-solving abilities between students who experienced the project-based learning model and those who underwent direct learning. In conclusion, the project-based learning model has a discernible influence on students' problem-solving abilities.

Abstract

This research aims to find out whether there is an influence and how the ability to use the photomath application has on students' mathematical problem solving abilities. This research is a quantitative research carried out at DWI SATYA Middle School with a pretest-posttest only one group design. The sample for this research was taken using a total sampling method of 15 students. This research instrument is a test of problem solving abilities in the form of a pretest and posttest. Furthermore, this research data was analyzed using a paired sample t-test after analyzing descriptive statistics and inferential statistics, namely the normality test and homogeneity test. The research results showed that the average pretest score for students who studied using the Photomath application was 36 and the posttest was 66 from the ideal score of 75. There was an increase of 30, which means there was an influence of using the Photomath application on students' mathematics learning with an N Gain score of 0.78 in the high category. Simultaneously, there is a significant influence of learning using the photomath application on students' mathematical problem solving abilities where a sig value of 0.000 is obtained which is smaller than the significance level of 0.05.
