Abstract

The acquisition of language is a crucial process in human cognitive and social development. This article discusses the stages of language acquisition in children and the bodily tools that support this process, such as the brain, nervous system, and speech apparatus. The research includes a theoretical analysis from linguistic and neurobiological perspectives and explores the roles of the brain and articulatory organs in language acquisition. Various theories from recent experts, including studies from the last five years, are employed to review the role of each bodily tool in supporting language acquisition. Through a literature approach and empirical research, this article reveals the interaction between biological development and social environment in the language acquisition process. The conclusion drawn is that language acquisition results from a complex interaction between inherent biological abilities and environmental stimulation, particularly social interactions

Abstract

Writing skills are an essential competency in Indonesian language learning, playing a significant role in developing students’ critical thinking and communication abilities. However, various studies indicate that students’ writing skills remain relatively low, particularly in generating ideas and organizing texts systematically. This study aims to analyze the teaching of writing skills through the process approach (prewriting, drafting, revising) and the Problem Based Learning (PBL) model based on recent literature. The method used is a literature review by analyzing relevant scholarly articles published between 2020 and 2024. The results of the review show that the writing process approach can gradually improve the quality of students’ writing, while the PBL model is effective in enhancing students’ motivation and critical thinking skills. The integration of both approaches provides a more optimal impact on writing skills. Therefore, process-based and contextual problem-based writing instruction is recommended for implementation in elementary schools.

Abstract

ABSTRACT This study aims to describe the implementation of Napier's Bones media in improving mathematics learning outcomes, particularly on multiplication of whole numbers, for third-grade elementary school students. The low mathematics learning outcomes, especially on multiplication, became the main issue underlying this research. A Classroom Action Research (CAR) design with two cycles was conducted at SDN 14/I Sungai Baung, Muara Bulian District, involving 20 third-grade students as research subjects. Data were collected through observation, tests (pre-test and post-test), interviews, and student response questionnaires, then analyzed descriptively both qualitatively and quantitatively. The results show that the implementation of Napier's Bones media significantly improved students' learning outcomes, as evidenced by the increase in average scores and learning completeness percentage from cycle I to cycle II. Napier's Bones converts multiplication problems into addition problems, enabling students to understand multiplication concepts concretely. This study contributes to strengthening the empirical foundation for using manipulative-based teaching aids in elementary school mathematics learning. Keywords: Napier's Bones Media, Learning Outcomes, Mathematics, Multiplication, Elementary School ABSTRAK Penelitian ini bertujuan untuk mendeskripsikan implementasi media Batang Napier dalam meningkatkan hasil belajar matematika, khususnya pada materi perkalian bilangan cacah, bagi siswa kelas III Sekolah Dasar. Rendahnya hasil belajar siswa pada mata pelajaran matematika, terutama materi perkalian, menjadi permasalahan utama yang melatarbelakangi penelitian ini. Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan desain dua siklus yang dilaksanakan di SDN 14/I Sungai Baung, Kecamatan Muara Bulian. Subjek penelitian adalah siswa kelas III yang berjumlah 20 orang. Pengumpulan data dilakukan melalui observasi, tes (pre-test dan post-test), wawancara, dan angket respons siswa. Data dianalisis secara deskriptif kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa penerapan media Batang Napier secara signifikan meningkatkan hasil belajar siswa, yang terlihat dari peningkatan nilai rata-rata dan persentase ketuntasan belajar dari siklus I ke siklus II. Penggunaan media Batang Napier mengubah persoalan perkalian menjadi persoalan penjumlahan sehingga memudahkan siswa memahami konsep perkalian secara konkret. Penelitian ini berkontribusi dalam memperkuat landasan empiris penggunaan alat peraga berbasis manipulatif dalam pembelajaran matematika di sekolah dasar.
