Abstract

The primary objective of this study is to ascertain the degree to which the implementation of the Problem Based Learning methodology can enhance students' interest in statistics content and mathematics learning outcomes. This investigation is a two-round classroom action research project. The study sample comprised 34 pupils enrolled in class X MPLB 5 at SMK Negeri 7 Medan. The process of gathering data was conducted via observation, questionnaires, and assessments. During the data collection phase, both teacher actions pertaining to the management of learning activities and student engagement in problem-based learning activities are assessed. Questionnaires are employed to determine the degree of interest that students have in mathematics courses. Subsequently, learning outcomes assessments are implemented to determine the degree to which pupils have comprehended the material. Based on the examination of research outcomes, one may deduce that the implementation of the Problem Based Learning pedagogical approach has resulted in enhanced scholastic performance and heightened student engagement with mathematics, particularly with regard to the domain of statistics. The observed performance increase is evident in the report of progress, which indicates a rise from 65% in the pre-cycle to 70% in cycle I, and subsequently to 95% in cycle II. The survey responses indicate that the proportion of students who are enthusiastic about acquiring knowledge in the field of mathematics rises as they progress from the pre-cycle stage to cycles I and II. More precisely, the proportion of pupils classified as "good" rose from 61.53% in the pre-cycle phase to 73.72 % in cycle I, and subsequently climbed to 87.73 percent in cycle II. The results of student learning assessments also demonstrate an upward trend. The proportion of accurate responses was 65.73% in the pre-cycle phase, 71.17% in cycle I, and 85 % in cycle II. Therefore, it can be inferred that the Problem Based Learning instructional strategy possesses the capacity to enhance students' scholastic performance and cultivate a passion for the study of mathematics

Abstract

The aim of this research is to improve students' mathematics learning outcomes through the problem-based learning (PBL) model using Curipod media. The research subjects consisted of 31 students of class XI TKR 4 at SMK Negeri 2 Medan, with data concentration measurement material. This type of research is classroom action research (PTK), which is carried out in two cycles, each cycle consisting of four stages: planning, implementation, observation and reflection. Based on the results of mathematics learning in the pre-cycle, it was found that only 8 out of 31 students or 25.8% achieved learning completeness, with a class average of 61.74. After implementing the PBL learning model using Curipod media in cycle I, the number of students who achieved learning mastery increased to 23 out of 31 students or 74.2%, with a class average of 76.68. At the end of cycle II, the number of students who achieved learning completion increased again to 28 out of 31 students or 90.3%, with a class average of 84.87. This shows an increase in student mathematics learning outcomes from pre-cycle to cycle II. Thus, it can be concluded that the application of the problem-based learning (PBL) model using Curipod media in class XI TKR 4 SMK Negeri 2 Medan can improve students' mathematics learning outcomes.

Abstract

This research is motivated by low student learning outcomes caused by minimal interaction between students and lack of active participation in the learning process. As part of our endeavour to enhance classroom learning, we seek to assess how the Make a Match cooperative learning paradigm affects students' arithmetic ability. Classroom Action Research (PTK) is the methodology used. The academic year 2024–2025 saw the research team from SMA Negeri 10 Medan doing their studies, with the research subjects being class XI IPA 4 students, namely 33 students, consisting of 13 men and 20 women. The research results show an increase in learning outcomes, especially in the material Deriving Algebraic Functions. In cycle I, 20 students achieved the KKM score (≥75) and 13 students did not achieve it. In cycle II, 26 students reached the KKM and 7 students did not. There was an increase of 18.18% from 6 students who previously did not reach the KKM. This shows the effectiveness of the Make a match cooperative learning model in improving student learning outcomes.

Abstract

Abstrak Pemahaman konsep matematis yang baik tentu saja tidak hanya diperuntukkan bagi anak-anak yang berada di wilayah yang memiliki tingkat pendidikan tinggi saja melainkan juga wilayah yang memiliki tingkat pendidikan yang rendah seperti wilayah tepian Sungai Deli. Wilayah tersebut masih mempunyai tingkat pendidikan yang minim maka pemahaman konsep matematis yang ada di lingkungan itu masih tergolong rendah dan masih banyak anak-anak yang buta terhadap matematika dasar seperti operasi hitung matematika. Maksud analisis ini ialah untuk mengoptimalkan pemahaman konsep matematis anak-anak di SASUDE berbantuan pojok alat peraga matematik (POLAGATIK). Kegiatan ini dilakukan di Sanggar Sungai Deli, Kec. Medan Maimun, Kota Medan, Sumatera Utara. Peserta kegiatan ini merupakan anak-anak berumur 7-13 tahun. Kegiatan ini menggunakan metode pendidikan masyarakat dengan empat langkah utama: persiapan, pelaksanaan, pemantauan, dan penilaian. Hasilnya menunjukkan peningkatan pemahaman konsep matematika anak-anak dari Pre-test ke Post-test sebesar 72%. Kegiatan tersebut berjalan dengan lancar dan mendapat tanggapan positif dari peserta anak-anak Kata kunci: pemahaman konsep matematis; alat peraga; POLAGATIK; SASUDE. Abstract A good understanding of mathematical concepts is of course not only intended for children in areas with a high level of education but also in areas with a low level of education such as areas on the banks of the Deli River. This area still has a minimal level of education, so understanding of mathematical concepts in that environment is still relatively low and there are still many children who are blind to basic mathematics such as mathematical calculation operations. The purpose of this analysis is to optimize children's understanding of mathematical concepts at SASUDE with the help of the mathematics teaching aids corner (POLAGATIK). This activity was carried out at Sanggar Sungai Deli, Kec. Medan Maimun, Medan City, North Sumatra. Participants in this activity are children aged 7-13 years. This activity uses a community education method with four main steps: preparation, implementation, monitoring and assessment. The results show an increase in children's understanding of mathematical concepts from Pre-test to Post-test by 72%. This activity ran smoothly and received positive responses from the child participants. Keywords: understanding mathematical concepts; props; POLAGATIK; SASUDE

Abstract

This study aims to analyze the understanding of Mathematics Education Study Program students towards the mathematical abilities of Junior High School (SMP) and Senior High School (SMA) students, as well as the factors that influence them. This study uses a descriptive quantitative approach with 35 fifth semester students of the Mathematics Education Study Program as research subjects. Data were collected using a questionnaire compiled based on indicators of students' understanding of mathematical abilities, problem-solving and mathematical reasoning abilities, pedagogical reflections of prospective teachers, and internal and external factors that influence students' mathematical abilities. Data were analyzed descriptively using percentages and classified into understanding criteria. The results showed that students' understanding of junior high school students' mathematical abilities was in the good category with a percentage of 82.04%, understanding of high school students' mathematical abilities was 82.71%, understanding of problem-solving and mathematical reasoning abilities was 81.58%, students' pedagogical reflection was 81.18%, and understanding of factors that influence students' mathematical abilities was 81.49%. Overall, the research results indicate that students have a good understanding of their role as prospective mathematics teachers, although some areas still require strengthening, particularly understanding student difficulties with specific material and developing ongoing pedagogical reflection. These findings are expected to inform the evaluation and development of the curriculum for prospective mathematics teachers.

Abstract

Sabun cuci piring yang banyak digunakan dan beredar di pasaran tidak sedikit menggunakan zat kimia aktif yang bisa dikatakan tidak ramah terhadap kulit manusia sehingga menyebabkan kulit terasa kering, gatal-gatal dan terkelupas. Namun, ada zat aktif lain yang bisa digunakan dalam pembuatan sabun pencuci secara alami, yaitu ekstrak sereh wangi dari tanaman sereh wangi. Oleh karena itu, penggunaan ekstrak serai wangi dalam pembuatan sabun cuci piring dianggap sangat efektif, tidak hanya untuk memberikan aroma, tetapi juga untuk memberikan efek antibakteri. Sebagaimana peneliti telah melakukan observasi awal ke lokasi yayasan, peneliti mendapatkan bahwa anak-anak berbagi peralatan makan yang sama. Kondisi ini menunjukkan adanya potensi tinggi terhadap penyebaran kuman dan bakteri, terutama melalui peralatan makan yang digunakan bersama tanpa adanya jaminan kebersihan yang optimal. Oleh karena itu keterampilan pemanfaatan ekstrak daun serai untuk pembuatan sabun cuci piring khususnya pada warga di Yayasan Al-Kahfi Medan Amplas akan sangat membantu menghemat biaya pembelian sabun dan meningkatkan keterampilan dalam memanfaatkan bahan alami untuk produk cuci piring.
