Abstract

Most children still have difficulty connecting number symbols with objects, ordering numbers, and performing simple arithmetic operations. This condition is exacerbated by limited availability of engaging learning media appropriate to early childhood development. Therefore, learning media development is needed. Domino Ceria (DORIA) is a set of domino cards with an attractive visual design used to improve understanding of number concepts in children aged 4–6 years. The research method used in this study is Research and Development (R&D) with the ADDIE model. The research subjects were Group B children of Trisula Perwari Kindergarten aged 4–6 years. The research instruments included needs analysis, expert validation, and effectiveness testing. The results showed that the Domino Ceria media met feasibility standards with an average percentage of 97.00% based on expert validation and proved effective in improving children's understanding of number concepts.

Abstract

Problem-solving skills are essential competencies that need to be developed during early childhood education. However, learning practices in many early childhood institutions are still teacher-centered, limiting children's opportunities to explore and solve problems independently. This study aimed to develop and examine the effectiveness of a DIY (Do-It-Yourself) learning model to improve problem-solving skills among children aged 5–6 years. The research employed a Research and Development (R&D) approach adapted from the ADDIE model consisting of analysis, design, development, implementation, and evaluation stages. The effectiveness of the model was tested using a pre-experimental design with a one-group pretest–posttest approach. The research participants consisted of 14 children from Group B at TK Negeri Parakanlima, Purwakarta. Data were collected using observation sheets measuring four indicators of problem-solving ability. The results showed a significant improvement in children's problem-solving skills, with the average score increasing from 52.43 in the pretest (developing category) to 80.36 in the posttest (very well-developed category). The N-Gain value of 0.65 indicated a moderate-to-high effectiveness level. The findings demonstrate that the DIY learning model can provide meaningful learning experiences through hands-on construction activities using recycled materials, encouraging children's independence, creativity, and critical thinking. Therefore, the DIY learning model can serve as an innovative pedagogical alternative to support the development of problem-solving skills in early childhood education.

Abstract

This study aims to develop an innovative learning medium called Rumah Pintar Gembira (MAHARIA) to improve the cognitive abilities of early childhood. The research was conducted using a Research and Development (R&D) approach with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The study was carried out in two early childhood education institutions, namely TK Sukakarya and TK Cemerlang in Sukabumi City, with children aged 4–5 years as the research subjects. The needs analysis revealed that cognitive learning media used in both institutions were limited and mostly consisted of worksheets and static picture cards. Most teachers (78–90%) expressed the need for concrete, manipulative, and interactive learning media, while the average cognitive ability of children was still in the low category (43.7%). Based on these findings, the MAHARIA learning media was developed in the form of a three-dimensional miniature house equipped with eight learning activity components designed to stimulate number recognition, one-to-one correspondence, classification skills, and simple problem-solving abilities. The feasibility of the media was validated by three experts consisting of one media expert and two material experts, resulting in an average feasibility score of 75.3%, categorized as feasible with revision. The effectiveness test was conducted using a comparative experimental design. The experimental group obtained an average N-Gain score of 0.51 (moderate category), which was higher than the comparison group with an average N-Gain score of 0.28 (low category). These findings indicate that the MAHARIA learning media contributes positively to improving early childhood cognitive abilities compared to conventional learning media. Therefore, the MAHARIA learning media can serve as an alternative innovative learning medium to support cognitive development in early childhood education.
