Abstract

Students typically need help understanding a succession of stories, relating mathematical concepts, and formulating them logically, systematically, and critically. Thus, students' math skills still need to improve. Students' mathematical intelligence, which has yet to be employed to solve story-form questions, affects their math abilities. This study examines MTs Walisongo Sukajadi class VIII students' mathematical and logical abilities. This research is quantitative and ex post facto. This study included 25 MTs Walisongo Sukajadi class VIII pupils. This study randomly selected 25 pupils from the population. Data is collected using surveys and tests. Data analysis uses Simple Linear Regression. This research found that Y = -8.728 + 0.958X is the regression equation from the analysis above. Statistical hypothesis testing yields Fcount = 50.200 and Ftable = 4.22. Since Fcount > Ftable and 0.000 > 0.05, H0 was rejected. This suggests that mathematical and logical intelligence positively and significantly affects SPLDV tale problem-solving. The R2 value of 0.686 shows how much mathematical and logical intelligence affects problem-solving. After utilizing the determinant method was 68.6%, meaning logical intellect contributed 68.6% to problem-solving, whereas other variables contributed 31.4%.

Abstract

This study aims to understand the role of simulation-based mathematics learning media in developing the cognitive abilities of early childhood. This media is an interactive approach that utilizes a digital or virtual environment to represent mathematical concepts in a concrete and engaging manner for children. Through simulation, children can explore, manipulate, and solve mathematical problems directly, thereby encouraging active engagement and meaningful learning. Recent studies have shown that the use of simulation media can improve conceptual understanding, critical thinking skills, and problem-solving abilities in early childhood. Simulation also provides an adaptive learning experience that can be tailored to the needs and learning styles of each child, effectively accommodating the diversity of cognitive abilities in the classroom. In addition, simulation media supports cognitive development in accordance with Piaget's and Vygotsky's theories, where children learn through active interaction with the environment and guidance from adults. This study highlights the importance of selecting and developing simulation media that are appropriate to the cognitive developmental stage of early childhood, as well as the need to evaluate the effectiveness of these media through valid and reliable measuring instruments. Thus, simulation-based mathematics learning media has the potential to be an innovative solution in improving the quality of mathematics learning and supporting the optimal cognitive development of early childhood.

Abstract

This research aims to develop an Edmodo-based e-learning media integrated with Macromedia Flash 08 for middle school students on sequences and series. The development of this media used a 3-D model (Define, Design, Develop) and focused on assessing the resulting product's validity, practicality, and effectiveness. Validation results showed that the developed learning media were highly valid, with a validity score of 4.68 from media experts and 4.62 from material experts. Regarding practicality, this media was deemed easy to use by teachers (score 4.53) and students (score 4.48). The media's effectiveness was also evident in the student learning achievement rate of 95% and the average positive student response rate of 89%. This learning media increased student interest and motivation in learning mathematics and made learning more engaging and interactive. However, there are challenges such as internet connection stability and the time required to access materials through Edmodo and Macromedia Flash. Overall, Edmodo-based e-learning media combined with Macromedia Flash 08 is a suitable alternative to support mathematics learning in the digital age.

Abstract

The learning model is a teacher's tool in the form of structured images that are presented to students. The learning model applied aims to improve students' understanding of mathematical concepts. The author determines the purpose of this study. Namely to assess the impact of experiments on the subject's knowledge of mathematical concepts in geometry material. This type of research uses experimental research using a mind mapping learning model with a pre-experimental design, one-group pretest-posttest. Tests were carried out randomly or through cluster sampling on building materials class VII Realschule. The data collection tool that the researchers used for this research was a test designed to test students' understanding of concepts. The researcher interviewed teachers, students, and documents in this data collection method. A hypothesis test was carried out on the data obtained after conducting a sig5% level t-test, normality test, and homogeneity test on statistical data. It was found that students could not understand mathematical concepts (mind mapping). This dramatically influences the results of understanding mathematical concepts. After using this method, students receive higher performance scores than before. Based on the t-test results, we can conclude the difference in the value of learning outcomes before and after applying the author's teaching method.

Abstract

Pembelajaran matematika di sekolah seringkali abstrak dan terpisah dari realitas kehidupan siswa, sehingga mengakibatkan rendahnya kemampuan literasi numerasi. Padahal, lingkungan siswa memiliki potensi konteks lokal berupa kegiatan peternakan domba yang kaya akan konsep matematika namun belum dimanfaatkan sebagai sumber belajar. Penelitian ini bertujuan untuk menganalisis potensi data nyata usaha peternakan domba untuk diubah menjadi bahan ajar, serta menyusun spesifikasi kebutuhan pengembangan LKPD berbasis konteks. Metode Penelitian: Penelitian ini menggunakan metode Penelitian dan Pengembangan (R&D) yang terbatas pada tahap pendahuluan, yaitu tahap Analisis. Teknik pengumpulan data dilakukan melalui observasi lapangan di kandang ternak, wawancara mendalam dengan peternak, dan dokumentasi. Instrumen penelitian meliputi pedoman wawancara dan lembar observasi. Analisis data dilakukan secara deskriptif kualitatif melalui empat tahap: analisis front-end, analisis tugas dan konsep (pencarian matematika), analisis karakteristik siswa, dan perumusan tujuan pembelajaran. Hasil analisis tugas dan konsep menunjukkan adanya konten matematika dalam kegiatan peternakan, yaitu: Aritmatika Sosial dalam data modal awal dengan rincian pembelian kambing dan biaya kandang, serta perbandingan harga jual pada hari kurban dan hari biasa, Perbandingan Nilai yang ditemukan dalam rasio campuran pupuk cair urin dibandingkan dengan air; Geometri dalam desain kandang yang ditinggikan dan literasi data tentang dinamika populasi beberapa domba dan tingkat kematian ternak. Konteks peternakan domba memenuhi syarat untuk dikembangkan menjadi cetak biru lembar kerja siswa (LKPD) menggunakan pendekatan pembelajaran berbasis masalah untuk meningkatkan kemampuan literasi numerasi siswa.

Abstract

Kualitas pendidikan matematika, khususnya materi Aritmatika Sosial di sekolah dasar, belum optimal dalam menghubungkan konsep dengan konteks dunia nyata, termasuk pengembangan keterampilan kewirausahaan yang penting di abad ke-21. Fenomena bimbingan belajar sebagai inisiatif kewirausahaan sosial menunjukkan kebutuhan mendesak akan materi pengajaran inovatif yang terintegrasi dengan nilai-nilai kewirausahaan sosial (Edu-Sociopreneurship) dan Moderasi Agama. Studi ini bertujuan untuk menganalisis kebutuhan pengembangan e-modul interaktif bernama “MathPreneur Modere” berdasarkan integrasi ini untuk meningkatkan keterampilan kewirausahaan siswa dan kualitas pembelajaran matematika di sekolah dasar. Studi ini menggunakan desain deskriptif kualitatif sebagai bagian dari tahap analisis (Analisis Kebutuhan) dalam penelitian pengembangan. Data dikumpulkan melalui teknik observasi (terkait dengan kewirausahaan jasa pendidikan dan kualitas pembelajaran), wawancara (guru dan siswa), dan kuesioner kebutuhan. Instrumen yang digunakan meliputi lembar observasi, pedoman wawancara, dan kuesioner kebutuhan pengembangan e-modul. Data dianalisis secara interaktif (reduksi data, penyajian data, dan penarikan kesimpulan) berdasarkan model Miles & Huberman. Hasil penelitian menunjukkan adanya urgensi yang tinggi terhadap modul elektronik yang dapat mengintegrasikan pendidikan matematika dan kewirausahaan, karena bahan ajar yang ada saat ini tidak memfasilitasi keterampilan kewirausahaan sosial dan nilai-nilai moderasi keagamaan. Modul elektronik ini diyakini sebagai solusi efektif untuk meningkatkan kualitas pembelajaran Matematika Sosial dan mengembangkan keterampilan kewirausahaan pada siswa sekolah dasar, sejalan dengan kebutuhan akan bahan ajar yang inovatif, mandiri, dan kontekstual.
