Improving the Ability to Classify Objects by Shape and Size Using Stones Among Children Aged 4–5 Years

Abstract

This study aimed to improve the ability to classify objects based on shape and size by using stone media among children aged 4–5 years at PAUD Kasih Ibu, Seluma Regency. The study was motivated by the low ability of children to recognize differences in shapes, classify objects based on similar shapes, distinguish object sizes, and describe the results of classification. This study employed the Classroom Action Research (CAR) method using the John Elliot model, which was conducted in two cycles. Each cycle consisted of four stages: planning, action, observation, and reflection. The research subjects were 15 children, consisting of 8 boys and 7 girls. Data were collected through observation, documentation, and field notes. The data were analyzed using descriptive quantitative and descriptive qualitative techniques. The results showed that the use of stone media improved children's ability to classify objects based on shape and size. The percentage of children's developmental achievement increased from 70% in Cycle I, categorized as Developing as Expected, to 99% in Cycle II, categorized as Very Well Developed. These findings indicate that stone media effectively improved children's ability to recognize shape differences, classify objects according to their shapes, distinguish object sizes, and describe the classification results. Therefore, stone media can be used as an alternative learning medium to enhance young children's cognitive development, particularly their ability to classify objects based on shape and size.
