Abstract

The Pre-Service Competency Teacher Level in Teaching Early Mathematics Instrument has been developed to measure the competency level and readiness to teach early mathematics in Preschool. This study was conducted to produce empirical evidence on the validity and reliability of this instrument by using the Rasch model. Surveys were conducted in three private universities that offer Early Childhood Education Programmes. A total of 85 pre-service teachers were selected as a sample of the study through simple random sampling. The validity and reliability of the instrument were measured using Rasch's model through Winstep software version 3.68.2. The findings of the unidimensionality test showed 46.1%. The Rasch analysis shows the person reliability index is 0.8 with a separation index is 2.05. The item reliability index is 0.91 and the separation index is 3.18. The item fitness analysis found 29 items in the instruments are in the valid range and one item that falls out of the allowed range. The finding showed that this instrument has a high degree of validity and reliability and can be used to measure the competency level of pre-service teaching in teaching early mathematics.

Abstract

Kreativitas anak usia dini penting untuk perkembangan kognitif, sosial, emosional, dan kemampuan memecahkan masalah. Namun, praktik pembelajaran PAUD masih kurang optimal karena minimnya media inovatif. Pada saat yang sama, meningkatnya limbah plastik membuka peluang pemanfaatannya sebagai media edukatif ramah lingkungan. Penelitian ini bertujuan meningkatkan kreativitas anak usia 4–5 tahun di KB Al Huda Pracimantoro melalui pemanfaatan limbah plastik. Menggunakan pendekatan kualitatif studi kasus, data diperoleh dari observasi, wawancara, dan dokumentasi terhadap 30 anak, kepala sekolah, dua guru, dan dua orang tua selama enam bulan (April–Oktober 2025). Hasil penelitian menunjukkan peningkatan signifikan pada empat aspek kreativitas: kelancaran ide (anak mampu menghasilkan rata-rata 3–5 ide karya berbeda dalam satu sesi), fleksibilitas (80% anak mampu mengombinasikan minimal tiga jenis bahan limbah), orisinalitas (karya unik seperti robot bergerak dan taman mini), serta elaborasi (anak menjelaskan karya dengan narasi imajinatif yang terstruktur). Anak menunjukkan antusiasme tinggi, percaya diri saat presentasi, dan kemampuan kolaboratif dalam kelompok. Kolaborasi guru dan orang tua turut mendukung keberhasilan kegiatan berbasis daur ulang ini. Secara praktis, temuan ini merekomendasikan integrasi limbah plastik sebagai media permanen dalam kurikulum PAUD untuk menstimulasi kreativitas sekaligus menumbuhkan kesadaran lingkungan. Penelitian lanjutan disarankan untuk mengkaji efektivitas jangka panjang dan penerapan di konteks PAUD dengan karakteristik sosial-ekonomi berbeda.
