Abstract

Penelitian ini bertujuan untuk meningkatkan pemahaman konsep matematis peserta didik pada materi fungsi komposisi dan fungsi kuadrat melalui penerapan model Problem Based Learning (PBL). Penelitian ini menggunakan metode Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus. Subjek penelitian adalah siswa kelas XI di SMA Negeri 3 Kisaran. Pada siklus I, hasil menunjukkan bahwa dari 34 siswa, 18 siswa (52,94%) mencapai ketuntasan, sedangkan 16 siswa (47,06%) belum tuntas, dengan rata-rata nilai siswa sebesar 65. Setelah perbaikan dilakukan pada siklus II, terdapat peningkatan signifikan dengan 30 siswa (88,24%) mencapai ketuntasan dan hanya 4 siswa (11,76%) yang belum tuntas. Rata-rata nilai siswa pada siklus II mencapai 86,76, dengan nilai tertinggi 100 dan nilai terendah 70. Hasil penelitian ini menunjukkan bahwa penerapan PBL efektif dalam meningkatkan pemahaman konsep matematis peserta didik, serta mendorong keterlibatan aktif dan kolaboratif dalam proses pembelajaran.

Abstract

This community service program is driven by the urgent need to improve the quality of primary education in rural areas, particularly at SDN 014686 Sidomulyo, North Sumatra, which faces significant challenges, including limited technological infrastructure, low numeracy and verbal skills among students, and a lack of innovation in teaching methods. This program aims to enhance students' cognitive and verbal abilities through the implementation of the abacus learning method combined with simple digital technology as an innovative and adaptive solution to these existing limitations. The activities were conducted using a descriptive qualitative approach, involving 60 second-grade students and two teachers. The program was carried out in five stages: socialization, training, technology implementation, mentoring, and evaluation, along with the sustainability of the program. Data were collected through observations, formative tests before and after the intervention, interviews with teachers and students, and activity documentation. Data analysis was conducted using the triangulation method to ensure the validity of findings from various sources. The results showed a significant improvement in students' numeracy skills, with an average score increase of 46.6% after three weeks of implementation. Additionally, students' verbal skills also demonstrated positive development, with average scores increasing from 2.4 to 4.0 on a five-point scale. Teachers reported improvements in pedagogical skills and began integrating digital tools into the teaching process. The use of a digital abacus application proved to enhance students' enthusiasm and active participation in mathematics learning. This program not only addresses existing academic challenges but also empowers teachers and creates an innovative learning model that can be replicated in other schools with similar conditions.

Abstract

This community service research aims to improve the spatial skills of elementary school students through local wisdom-based geometry learning with geoboard media. The main problem faced is the low understanding of students towards geometry concepts due to the abstract and less contextual learning approach. The method used is Participatory Action Research (PAR) which actively involves teachers and students in planning, implementation, and evaluation. The activity was carried out at UPTD SDN 014686 Sidomulyo, with the participation of 90 grade III students. The results showed a significant increase in students' spatial skills: 88% of students found it easier to understand geometric shapes, 91% showed active involvement, and 94% hoped that this method would continue to be used. In addition, 100% of teachers stated that this method was effective and increased their confidence in teaching. The use of geoboards and the integration of local cultural motifs have been proven to create contextual, enjoyable, and meaningful learning experiences. The conclusion of this activity is that local wisdom-based geometry learning with the help of geoboards is effective in improving students' spatial skills and is relevant to be applied widely

Abstract

The integration of technology in education necessitates that future teachers acquire the skills to design and implement effective digital learning media. The Merdeka Curriculum, particularly through its Alur Merdeka framework, emphasizes flexible and independent learning, aligning with this need. This study aimed to develop and evaluate a Digital Learning Media module grounded in the Alur Merdeka approach to improve student competencies in educational technology. A Research and Development (RD) methodology was applied, guided by the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). Module validity was assessed by expert reviewers. Practicality was gauged through student response questionnaires, and effectiveness was measured using N-Gain Scores from pretest and posttest results. The module demonstrated high validity (87.6%) and strong practicality (84%) based on expert evaluations and student feedback. Effectiveness testing showed a significant improvement in students’ competencies, with an N-Gain Score of 0.72, categorized as high. The findings confirm that the Alur Merdeka-based module is a valid, practical, and effective tool for supporting independent learning in teacher education. Its implementation can enhance prospective teachers’ ability to develop technology-driven instructional media. This study contributes to the development of flexible, competency-based digital learning resources in alignment with the Merdeka Curriculum, supporting the broader integration of technology in teacher education programs.

Abstract

The study aimed at finding out in dept about the interaction between Problem Posing model assisted with Autograph Software with the student’s gender to students' mathematical communication ability. This study used quantitative research with quasi experimental method. The approach used was a scientific one. The population of this study were all the Class X students of MAN Kisaran. The sample in this study were the students of class X-IPA1 and X-IPA-2 in MAN Kisaran of Asahan Regency. This study was conducted in the even semester of the academic year 2017/2018. Data analysis was done by 2-way ANOVA test. Based on the statistical calculation, it can be concluded that the value of Fcount<Ftable is 0.778 <3.12. This shows that Fcount<Ftable(0.778 <3.12) is not significant so that it can be concluded that H0 is accepted and Ha is rejected which means there is no interaction between learning with students’ gender. The finding of students’ actitivity aspects is based on direct observation. Female students are more active in learning but are weaker in reasoning, meanwhile Male ones are quick in reasoning but are less active in learning.
