Abstract

This study aims to examine the impact of a volcanic eruption experiment on the cognitive development of early childhood students at TK Al-Hikmah Ketapang Banyuwangi. Using an experimental method with a One-Group Pretest-Posttest design, the sample consisted of 15 children from group B1. The results showed a significant increase in the children's cognitive abilities after the treatment. Before the treatment, most children were in the "Not Yet Developed" and "Starting to Develop" categories. After the treatment, there was a significant increase to the "Developing as Expected" and "Developing Very Well" categories. The Wilcoxon test indicated that this experiment positively influenced the children's cognitive development. Nature-based science learning not only enhances cognitive abilities but also motivation, social skills, and both physical and mental health of children. This method is effective in integrating direct experiences with the natural environment to prepare children for future challenges.

Abstract

This study aims to examine the impact of nature-based science learning on the cognitive development of early childhood students at TK IT Nada Ashobah Wiyung Surabaya. The research method used is a quasi-experimental design with a one- group pretest-posttest design. The population in this study consists of all group B children at TK IT Nada Ashobah, totaling 15 children. The sampling technique used is saturated sampling. The sample consists of 15 group B children. The results show a significant improvement in children's understanding of plant parts after the treatment. The pretest indicated that most children were in the "Starting to Develop" category, while the posttest showed an increase, with the majority of children in the "Developing Very Well" category. The Wilcoxon test showed an Asymp (2-tailed) value of 0.001, indicating that nature-based science learning has a significant impact on children's cognitive development. The study concludes that the nature-based learning approach is effective in enhancing children's understanding and interest in science and recommends integrating this method into the early childhood education curriculum.
