Abstract

Thinking skills are very important in learning mathematics because, with the help of mathematical reasoning, students can develop their thinking skills in mathematics. This research aims to improve students' mathematical reasoning abilities by using a project-based learning model (PjBL). This study uses a quantitative approach with a pre-experimental design, designed in a one-group pretest and posttest design. The population in this study were all students of SMP AW 8 (UNIVA) Medan which consisted of five classes. The research sample consisted of one class, namely class fourth with a total of 12 students selected by simple random sampling. Data collection techniques use students' mathematical reasoning abilities in the form of descriptive questions. The instrument used is a mathematical reasoning test consisting of pretest and posttest questions which will be used after testing the validity, reliability, level of difficulty, and discriminating power. The data analysis technique used to test the hypothesis is a paired sample t-test to find differences in students' mathematical reasoning abilities in the research class and get points to determine the increase in students' mathematical reasoning abilities. The results of the analysis using the sample t-test were obtained with a value of t_count = -27.735 <t_table = -2.20 indicating that students' mathematical reasoning abilities increased by using the project-based learning (PjBL) learning model. Students' mathematical reasoning ability increased in high class with an average score of 0.71

Abstract

Penelitian ini bertujuan untuk meningkatkan literasi digital dan kreativitas siswa sekolah dasar melalui pelatihan pembuatan animasi pembelajaran dengan Microsoft PowerPoint. Kegiatan dilaksanakan selama dua hari di SDIT AL-Habib dengan melibatkan 20 siswa kelas 5B. Metode yang digunakan adalah edukatif-partisipatif dengan pendekatan project-based learning. Hasil penelitian menunjukkan peningkatan signifikan dalam kemampuan teknis siswa menggunakan fitur PowerPoint, peningkatan kreativitas dalam menyusun media pembelajaran, serta peningkatan kepercayaan diri dalam mempresentasikan karya. Sebanyak 80% siswa berhasil menguasai materi dengan baik, sementara 20% memerlukan pendampingan intensif. Evaluasi dilakukan melalui observasi partisipasi, penilaian karya, dan presentasi hasil. Kegiatan ini membuktikan bahwa pembelajaran berbasis multimedia dapat meningkatkan minat belajar siswa dan mendukung pengembangan keterampilan abad 21. Disarankan untuk mengadakan pelatihan serupa secara berkelanjutan dengan dukungan fasilitas yang memadai.

Abstract

The purpose of this study is to develop a valid, practical, and effective Minangkabau local culture-based Student Worksheet (LKPD) to improve students' mathematical communication skills at SMA Negeri 3 Padang. This study uses the Research and Development (R&D) method with the ADDIE development model. The subjects of this study were 32 grade X students of SMA Negeri 3 Padang. Observation sheets, practicality questionnaires, mathematical communication ability tests, and validation sheets were the research instruments. The results showed that the developed LKPD met the valid criteria with an average validation score of 3.65 which is a very valid category, practical with an average practicality score of 3.72 which is a very practical category, and effective with an average N-gain score of 0.74 which is a high category. This LKPD integrates the context of Minangkabau local culture such as the traditional house, songket weaving, and rendang in mathematical materials, especially geometry and linear equation systems. This study concludes that local culture-based LKPD can be an effective alternative teaching material to improve students' mathematical communication skills.

Abstract

This study aims to describe the types of mathematics learning difficulties experienced by students at MTs Muallimin Univa Medan and the contributing factors. The research method used is descriptive qualitative. The research subjects consisted of 7th- grade students and mathematics teachers. Data collection was conducted through classroom observations, in-depth interviews, and diagnostic test analysis. The results showed that the students' main difficulties included difficulty in understanding abstract concepts, weaknesses in basic arithmetic operations, and low contextual problem-solving abilities. The factors causing these difficulties stem from internal factors (low motivation and math anxiety) and external factors (less varied teaching methods and lack of learning support at home).

Abstract

Technological developments require teachers to integrate interactive digital media to improve the quality of 21st-century learning. However, early observations at SMP Negeri 3 Tanjung Beringin showed that the utilization of web-based learning media was not optimal despite the availability of supporting facilities. This community service activity aims to introduce the Wordwall platform as an interactive learning media solution and to enhance teachers’ pedagogical competence in operating its features. The implementation method uses a learning-by-doing approach, which includes the preparation stage, workshops through lectures and demonstrations, independent practice in content creation, and evaluation. The results show a significant increase in teachers’ understanding and technical skills in developing digital learning media. Teachers were able to explore quiz features, games, and even printable formats (PDF) to overcome network constraints. In conclusion, this activity successfully narrowed the digital literacy gap and increased teacher motivation to create a more dynamic and student-centered learning environment at SMP Negeri 3 Tanjung Beringin.
