Abstract

Kemampuan numerasi murid di Indonesia masih belum memadai, meskipun kompetensi ini penting untuk persiapan akademik dan keikutsertaan dalam Asesmen Nasional (AS). Kemampuan numerasi murid yang belum memadai perlu dicarikan solusinya. Salah satu upaya yang diusulkan oleh para peneliti adalah pengembangan media pembelajaran berbasis digital. Aplikasi E-NuMeka diharapkan dapat meningkatkan kemampuan numerasi murid. Proyek ini bertujuan untuk membuat platform media digital "E-NuMeka" yang memenuhi persyaratan validitas, kepraktisan, dan efektivitas untuk meningkatkan literasi numerasi murid. Penulisan ini menggunakan Software Development Life Cycle dengan menggunakan teknik prototyping sebagai metodologi penulisan dan pengembangannya. Aplikasi E-NuMeka yang dikembangkan dinilai valid dan layak untuk digunakan, serta memperlihatkan efektivitas dalam meningkatkan kemampuan numerasi matematika murid. Hal ini dibuktikan dengan analisis Paired Samples Test, yang mana signifikansi (2-tailed) dengan asumsi varians yang sama adalah 0,000, yang berarti lebih kecil dari 0,05. Aplikasi E-NuMeka dinilai praktis, dengan skor evaluasi kuesioner murid rata-rata 80,20. Penulisan ini memperlihatkan jika program E-NuMeka dapat meningkatkan kemampuan literasi numerasi matematika di kalangan murid sekolah menengah atas.Students' numeracy skills in Indonesia are still inadequate, although this competency is important for academic preparation and participation in the National Assessment (AN). Students' inadequate numeracy skills need to be solved. One of the efforts proposed by researchers is the development of digital-based learning media. The E-NuMeka application is expected to improve students' numeracy skills. This project aims to create a digital media platform "E-NuMeka" that meets the requirements of validity, effectiveness, and practicality to improve students' numeracy literacy. This study uses the Software Development Life Cycle using prototyping techniques as its research and development methodology. The E-NuMeka application developed was considered valid and feasible to use with the results of the validation of material experts obtaining an average value of 88.75 and 90, then the average validation assessment from media experts was 79 and 77.66 with a valid category. And shows the effectiveness in improving students' mathematical numeracy skills, this is proven by the Paired Samples Test analysis, where the significance (2-tailed) assuming the same variance is 0.000, which means it is less than 0.05. The E-NuMeka application is considered practical, with an average student questionnaire evaluation score of 80.20. This study shows that the E-NuMeka program can improve mathematical numeracy literacy skills among high school students.

Abstract

This research aims to design and determine the feasibility and effectiveness of LKPD Poster Learning Media (POLKA PD) to improve students' mathematical understanding, especially in flat-sided geometric material. This research uses Research and Development (R&D) research with the ADDIE development model and research design using one group pretest-posttest design. The population of this study only consisted of class VIII students at MTs Negeri 3 Kuningan for the 2023/2024 academic year. The sampling technique used in this research was simple random sampling. From the research results, it was found that the POLKA PD media developed was suitable for use in educational environments, based on the verification results of media experts and material experts. The POLKA PD media developed is effective in increasing students' mathematical understanding. This can be seen from the average student mathematics comprehension test score after using POLKA PD media which is higher than before. The development of POLKA PD media on flat-sided geometric material received a good response from students. This can be seen from the results of a survey of student responses to POLKA PD media

Abstract

This study aims to determine the validity and effectiveness of the mathematical comic learning medium (KOMKA) to improve the numeration ability of elementary school students especially on area & volume measurement materials. This type of research is Research and Development. The development model used is the ADDIE model developed by Dick and Carey, which has five stages: Analysis, Design, Development, Implementation, and Evaluate. The population in this development research is all students of SDN 2 Padarek in the 2023/2024 academic year. The sampling technique used in this development research is simple random sampling. The data analysis technique used in this study is a descriptive analysis technique to describe whether the digital comics developed by the study are valid and effective for use in class learning. Research results show that the KOMKA learning medium is valid for use in learning activities, derived from the validity results of media experts and material experts. The KOMKA learning medium is effective in improving students' numeration skills. This can be seen from the average test results of students' mathematical understanding ability after the application of the KOMKA learning medium was higher than before.

Abstract

This study aims to describe the success of the Problem Solving model in improving students' mathematical problem-solving skills from the perspective of learning motivation. This study uses a sequential explanator design. The research sample consisted of 36 students of SMP Negeri 3 Darma for the 2023/2024 academic year, namely 18 VIII A students as the experimental group and 18 VIII B students as the control group. The instruments used are tests and questionnaires. Data analysis was carried out using 2-Path Variance Analysis. The results of the data analysis were known with a significance level of 5% that in the learning model factor, a value of 0.000 < 0.05 was obtained with the conclusion that there was a difference in mathematical problem-solving ability between students who were given Problem Solving learning and conventional learning. Hypothesis testing of learning motivation factors had a value of 0.307 > 0.05 with the conclusion that there was no difference in mathematical problem-solving ability between students and High, medium, and low learning motivation

Abstract

Asesmen kompetensi minimum adalah penilaian yang dilakukan untuk mengukur literasi, numerasi dan karakter siswa. Rendahnya tingkat kemampuan numerasi menjadi persoalan yang sangat penting untuk perkembangan pendidikan khusus bagi siswa sekolah dasar sampai atas. Perlu adanya solusi untuk peningkatan kemampuan literasi numerasi matematika siswa ini, dan model Problem Based Learning (PBL) dapat menjadi alternatif untuk meningkatkan kemampuan literasi numerasi siswa. Selanjutnya tujuan dari penelitian ini adalah ingin mengetahui apakah model Problem Based Learning (PBL) ini mampu membantu meningkatkan kemampuan literasi numerasi matematika siswa sekolah menengah pertama (SMP) atau Madrasah Tsanawiyah (MTs). Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan menggunakan model Kurt Lewin yaitu perencanaan, tindakan, observasi, dan refleksi. Hasil penelitian pada pra siklus menunjukan bahwa hanya dua siswa yang telah mencapai nilai ketuntasan atau sekitar 6,3% dengan rata-rata nilai numerasi 41,4. Selanjutnya setelah diberikan tindakan kelas pada siklus I, siswa yang tuntas mengalami kenaikan menjadi 10 siswa atau 31% siswa telah tuntas dengan nilai rata-rata 55,8. Karena belum mencapai indikator keberhasilan, dilakukan tindakan siklus II, didapat 24 siswa dinyatakan lulus dengan nilai rata-rata 74,9 atau 75% siswa telah tuntas. Dengan demikian indikator keberhasilan tindakan terpenuhi yaitu lebih atau sama dengan 75% siswa mencapai ketuntasan. Maka dapat diambil kesimpulan bahwa model PBL dapat membantu meningkatkan kemampuan literasi numerasi matematika siswa.

Abstract

Understanding the concept of fraction division is a basic skill that is important for second-grade junior high school students to master. This study aims to describe the level of students' understanding of the concept of fraction division. This study used a descriptive qualitative approach with data collection techniques through observation and interviews with six second-grade students of Oikumene Junior High School. The results showed that most students did not understand the basic concept of fraction division, including the inverse procedure in division operations and the identification of numerators and denominators. Although some students claimed to understand the terms numerator and denominator, they were unable to show them correctly in the form of a given fraction. The conclusion of this study shows that a weak understanding of the basic concept of fractions is one of the main causes of students' difficulties in solving fraction division problems, so a more contextual and conceptually oriented learning approach is needed.
