Abstract

Cognitive development in early childhood is an important phase in forming the foundation of a child's intellectual growth. First, the sensorimotor phase highlights the importance of sensory and motor stimulation in early childhood. Children learn through touch, sight and physical movement, which form the basis for understanding the world around them. Then, the preoperational phase marks the development of symbolic thinking and language skills. Children's creativity and imagination flourish, while their understanding of the concepts of space and time begin to develop. Next, the concrete operational phase shows the child's ability to think logically and understand abstract concepts with the help of concrete objects. Cognitive processes become more complex, and children are able to connect concepts in greater depth. Finally, the formal operational phase marks the child's ability to think abstractly and develop more complex problem-solving skills. Social interactions, educational play and supportive learning experiences all play a key role in forming the foundation of intellectual growth. This understanding also forms the basis for designing effective educational programs, ensuring that children can optimize their cognitive potential during this critical period of development.

Abstract

Children aged 0-6 years are at an age where cognitive development is very rapid. Counting ability is one of the things that cannot be ignored in this case. The Ethnomathematics approach is an approach that prioritises cultures that contain mathematical values This study aims to determine the ethnomathematics approach to counting skills 1- 20 students aged 4-6 years. This research is a quasi-experimental research with posttest only control design, with a sample of 22 children out of 44 students at RA Al-Qur'an Dina Padang Matinggi. The results showed a significant effect of initial counting ability on the final counting ability of experimental class students using the ethnomathematics approach.experimental class students who used the ethnomathematics approach. Statistical results show the value of F = 18,861 with a significance of 0.000 (p < 0.05). The Ethnomathematics approach can be used in the learning process at the early childhood education level. So that counting skills can develop through this approach. And of course it is necessary to pay attention to the understanding of the culture possessed by students after the learning process is carried out

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh video animasi Nusa dan Rara terhadap kemampuan bercerita anak usia 4-5 tahun di PAUD Mawar, Kota Padangsidimpuan. Hal ini didorong oleh adanya anak-anak yang masih mengalami kesulitan dalam bercerita dan pengucapan kosakata mereka juga belum lancar. Jenis penelitian yang digunakan adalah kuantitatif dengan metode eksperimental (Quasi Experimental Design). Dalam penelitian ini terdapat 2 kelas, yaitu kelas eksperimen dan kelas kontrol. Metode yang digunakan dalam menganalisis data penelitian meliputi normalitas, homogenitas, dan uji hipotesis. Pada kelas eksperimen yang berjumlah 22 anak, nilai awal (pretest) diperoleh rata-rata 16,68 dengan kategori rendah atau buruk dan nilai akhir (posttest) diperoleh rata-rata 25,86. Sedangkan pada kelas kontrol yang juga berjumlah 22 orang, hasil pretest diperoleh nilai 13,81 dan nilai akhir (posttest) diperoleh rata-rata 27,13. Distribusi data yang dihasilkan memiliki distribusi normal dan homogen. Untuk uji hipotesis, terlihat bahwa T(hitung) (4,690)> T(tsbel) (4,690) yang menunjukkan bahwa Ha diterima dan Ho ditolak. Ini berarti bahwa terdapat pengaruh video animasi Nusa dan Rara terhadap kemampuan bercerita anak-anak di PAUD Mawar Padangsidimpuan City.

Abstract

This research is driven by the limited use of mathematics learning tools such as teaching modules in schools. At MA Al-Junaidiyah in Mandailing Natal Regency, learning still largely relies on textbooks based on the 2006 curriculum, resulting in low student achievement in mathematics, particularly in the topic of algebraic function limits. This study aims to determine the validity, practicality, and effectiveness of a Mathematics Learning Module developed using the Missouri Mathematics Project (MMP) Model for the topic of Algebraic Function Limits for Grade XI students at MA Al-Junaidiyah. The research follows the Research and Development (R&D) methodology with the ADDIE development model comprising five stages: Analysis, Design, Development, Implementation, and Evaluation. Module validation involved experts in content, media, and language. The trial was conducted with 23 students of class XI-2. Two validators were assigned for each area. Results showed that the module achieved an overall validity score of 84.29%, categorized as valid. Its practicality reached 89.75%, categorized as practical. Student learning effectiveness reached 47%, showing the module is effective in improving learning outcomes. Therefore, the module is deemed feasible, engaging, and beneficial for enhancing student achievement.

Abstract

This study is motivated by the lack of use of mathematics learning tools such as student worksheets (LKPD) at MAS Darul Istiqomah Padangsidimpuan, where teacher handbooks and textbooks are more frequently used. Additionally, the students' mathematics learning outcomes, particularly in the topic of arithmetic sequences and series, are low. This study aims to assess the validity, practicality, and effectiveness of student worksheets (LKPD) based on brain-based learning (BBL) using crossword puzzles in the topic of arithmetic sequences and series for class X at MAS Darul Istiqomah Padangsidimpuan. This research is a research and development (R&D) study. The development model used in this research is the 4D model, which consists of four stages: Define, Design, Development, and Disseminate. The validation of the LKPD includes material validation, media validation, and language validation. The trial was conducted in class X-B, with a total of 19 students at MAS Darul Istiqomah Padangsidimpuan. The material experts, media experts, and language experts each consisted of 2 validators. The results of this study indicate that the developed LKPD meets the eligibility criteria, with an overall validation percentage of 87.32%, categorized as valid. The practicality of all aspects is shown by a value of 85.63%, categorized as very practical. The effectiveness is indicated by an average student learning outcome score of 71%, calculated from the overall average learning outcomes of the students, categorized as effective. Therefore, it can be concluded that the LKPD is feasible, engaging, and capable of improving student learning outcomes.

Abstract

Program pengabdian ini bertujuan untuk meningkatkan kompetensi guru Matematika SMA Negeri 1 Batang Angkola dalam merancang dan membuat multimedia interaktif berbasis Canva sebagai upaya mendukung pembelajaran yang lebih menarik dan komunikatif. Kegiatan ini dilaksanakan dengan metode partisipatif yang melibatkan guru secara aktif melalui observasi awal, wawancara, pelatihan intensif, pendampingan individual, serta evaluasi hasil. Pelatihan berfokus pada pemanfaatan Canva untuk mengembangkan media pembelajaran pada materi barisan dan deret aritmatika. Hasil pengabdian menunjukkan adanya peningkatan signifikan dalam kemampuan guru memvisualisasikan konsep matematika secara lebih jelas melalui animasi, grafik, dan elemen interaktif. Guru yang sebelumnya terbatas pada media statis kini mampu menghasilkan produk multimedia yang sesuai dengan prinsip desain instruksional modern seperti hierarki visual dan pengurangan beban kognitif. Pendampingan individual terbukti membantu percepatan penguasaan fitur Canva, terutama bagi guru yang memiliki kemampuan teknologi dasar. Selain itu, pelatihan ini juga meningkatkan kompetensi TPACK guru, ditandai dengan kemampuan mereka mengintegrasikan aspek teknologi, pedagogi, dan konten matematika secara efektif. Temuan ini menegaskan bahwa Canva merupakan platform yang praktis dan relevan untuk mendukung pembelajaran matematika di sekolah menengah.
