Abstract

This study aims to develop a contextual mathematical literacy instrument based on local wisdom that is valid, reliable, and practical for junior high school students. The development of this instrument was motivated by the limited availability of assessment tools capable of measuring students’ mathematical literacy comprehensively and in alignment with their cultural contexts. The research employed the ADDIE development model, consisting of five stages: analysis, design, development, implementation, and evaluation. The study involved 30 students from a junior high school in Tangerang Regency. Data were collected through written tests, expert validation sheets, classroom observations, and practicality questionnaires. The results of expert validation showed an average score of 4.65, indicating that the instrument is highly valid. Field trials revealed a reliability coefficient of α = 0.89, suggesting high internal consistency. Furthermore, the practicality and acceptability levels reached 88.7% and 90.3%, respectively, both categorized as very good. These findings indicate that the developed contextual mathematical literacy instrument based on local wisdom is feasible for use as an authentic assessment tool to evaluate students’ mathematical literacy skills in a meaningful and culturally relevant manner.

Abstract

Program Kampus  Mengajar merupakan  bagian dari kebijakan Merdeka Belajar Kampus  Merdeka(MBKM) dari Kementerian Pendidikan, Kebudayaan, Riset dan Teknologi. (Kemendikbudristek). Program  ini  menghadirkan mahasiswa dari  seluruh  program  studi  di perguruan  tinggi  untuk  berkontribusi  dalam  rangka penguatan literasi dan numerasi.  Kabupaten Tangerang adalah salah satu daerah penempatan mahasiswa program Kampus Mengajar. Tujuan dari  penelitian  yang  dilakukan  adalah melihat bagaimana implementasi program Kampus Mengajar, selain itu melihat bagaimana capaian literasi  numerasi  siswa  di salah satu sekolah dasar di Kabupaten  Tangerang. Metode penelitian yang  digunakan  adalah  deskriptif  kuantitatif dengan uji paired sample t-test dengan  peneliti  bertindak  sebagai  observer.  Hasil penelitian menunjukan bahwa siswa tertarik dengan pembelajaran  berbantukan media pembelajaran  dan  metode  pembelajaran  yang  dilakukan  secara  berkelompok  membuat  pembelajaran  sangat efektif  sehingga  perkembangan  keterampilan  dan  numerasi  terdapat  peningkatan  pada  kelompok  siswa  belum fasih membaca dan semakin baik pada kelompok siswa yang sudah fasih membaca.

Abstract

Siswa umumnya takut matematika karena dianggap sulit dipahami. Penelitian ini bertujuan untuk meningkatkan prestasi matematika siswa kelas VIII SMP Al Fattah Tigaraksa 2022/2023 dengan menerapkan metode pembelajaran IMPROVE. Metode penelitian yang digunakan adalah eksperimen dengan desain siklus. Hasilnya menunjukkan bahwa metode IMPROVE dapat meningkatkan prestasi matematika siswa. Nilai ketuntasan klasikal untuk prestasi belajar matematika siswa untuk KD Keterampilan meningkat dari 48,3% pada kondisi awal menjadi 72,4% pada siklus 1 dan 89,6% pada siklus 2. Hal ini menunjukkan bahwa pembelajaran kooperatif IMPROVE dapat meningkatkan kualitas pendidikan matematika.

Abstract

This study aims to identify the Learning obstacles experienced by students in learning quadrilaterals and to analyze how these obstacles indicate the emergence of a conceptual crisis. The method used is a descriptive qualitative approach involving junior high school students as research subjects. Data were collected through diagnostic tests, interviews, and classroom observations to explore students’ learning difficulties in greater depth. The findings show that students still encounter various types of Learning obstacles, including ontogenic, epistemological, and didactical obstacles. These obstacles are evident in students’ inability to understand basic concepts, difficulties in connecting different representations of geometric figures, and the mismatch between teachers’ instructional strategies and students’ learning characteristics. These conditions indicate the presence of a conceptual crisis that may hinder students’ understanding of more complex mathematical concepts. In conclusion, this study emphasizes that the Learning obstacles identified are influenced not only by students’ initial abilities but also by instructional resources and the teaching approaches used. The findings contribute theoretically to the discussion of Learning obstacles in mathematics education and provide practical recommendations for teachers in designing geometry instruction that is more contextual, interactive, and conceptually oriented.
