Abstract

Early numeracy skills are crucial for young children's cognitive and mathematical development, particularly during the preoperational stage (ages 2-7), when they begin to develop symbolic thinking and foundational mathematical concepts. This study investigates the progression of early numeracy skills in two preschool-aged children (Child H and Child K), focusing on their ability to engage with numeracy concepts such as counting, cardinality, numeral identification, and number combination. Using a qualitative case study approach, the research observes the children's numeracy behaviors through assessments and direct observation during play-based learning activities. Findings reveal notable differences in the children’s numeracy development: Child H demonstrates stronger skills in one-to-one counting, subitizing, number ordering, and problem-solving, while Child K shows emerging abilities but struggles with tasks such as number comparison and number combination. These differences highlight the variability in the development of numeracy skills, with confident children progressing more rapidly in their understanding of numbers and relationships. The study emphasizes the importance of concrete, hands-on learning experiences in developing mathematical thinking, mainly through physical manipulatives and interactive, game-based activities. The results underscore the need for tailored learning experiences to support children in the preoperational stage, which has implications for early childhood educators in fostering a strong mathematical foundation.

Abstract

Kemampuan numerasi awal merupakan faktor kunci dalam menentukan kesuksesan akademik anak di masa depan. Namun, perhatian terhadap pengembangan keterampilan numerasi awal masih belum memadai. Penelitian ini bertujuan untuk mengevaluasi penelitian-penelitian sebelumnya melalui metode analisis konten terhadap artikel-artikel ilmiah yang dipublikasikan di jurnal internasional mengenai numerasi awal. Data dikumpulkan dari SciSpace sebanyak 108 artikel, dengan fokus pada jenis penelitian, subjek, instrumen, dan keterbatasan penelitian. Temuan menunjukkan dominasi penelitian kuantitatif dan kekurangan penelitian kualitatif serta R&D. Selain itu, terdapat sedikit perhatian terhadap guru sebagai subjek penelitian dan keterbatasan ukuran sampel. Penelitian ini merekomendasikan pengembangan metode, model, serta pendekatan baru yang lebih beragam untuk meningkatkan kualitas dan pemahaman tentang kemampuan numerasi awal.

Abstract

Preschool education is important for developing children’s social and cognitive skills, with early mathematical ability being a strong predictor of future success. This study evaluated the psychometric properties of the Preschool Home Mathematics Questionnaire (PHMQ) using Rasch Model Analysis. A total of 95 parents and guardians of preschool-aged children participated in the study. A total of 37 Likert-scale items were analysed. The results showed excellent person reliability (0.93) and item reliability (0.96), indicating strong consistency and well-targeted item difficulty. Of the 37 items, 32 were valid according to the Rasch fit criteria, while five items (Q13, Q15, Q22, Q24, and Q26) showed misfit based on the Outfit mean square (MNSQ), Z-standard (ZSTD), and PTMEA-CORR. The Likert scale functioned well with ordered thresholds and smooth transitions between categories. The unidimensionality test confirmed that the PHMQ measures a single construct, with 44.1% of the variance explained and only 12.8% unexplained in the first contrast. While the PHMQ shows good validity and reliability, this study focused only on basic Rasch validation. Future research should explore differential item functioning (DIF), item bias, and long-term stability to further improve this instrument and support its use in different settings.
