Development of Science Teaching Books Based on Fun Experiments for Early Childhood (5-6 year-olds) in the Kindergarten of Kutalimbaru Subdistrict, Deli Serdang Regency

摘要

This research is motivated by the availability of textbooks that are not in accordance with the needs and conditions of the child's environment, so that the introduction of science learning for early childhood has not been carried out optimally. The aim of this research is: 1) To know the feasibility of using experimental science-based textbooks is fun for early childhood (5-6 years old) which was developed. 2) To know the effectiveness of the development of textbooks produced in improving cognitive abilities in children aged 5-6 years. The subjects in this study were group B students in the Islamic Kindergarten Integrated MTTQ School Kutalimbaru 2018-2019 of Academic Year, totaling 36 students. This type of research is research and development (R&D). The development of textbooks is based on 4-D model development research (Four D Models) according to Thiagarajan which includes 4 stages namely the defining stage (define), design, development, and disseminate. The research results obtained that (1) The level of feasibility of based science textbooks is fun based on: a) the results of the validation of the material expert on the feasibility of the contents of the developed textbooks are included in the "Good" category. b) Practical results from teachers stated that all teachers need science-based textbooks that are fun experimentation in the learning process because the books provided are not only for students but have guidelines in the form of teacher's books. (2) The results of the effectiveness of the textbooks developed showed that the cognitive abilities of children after using science-based textbooks for experimentation were higher than just using magazines and posters as learning media. Where the average initial value of the child is 50 and the final test increases to 75.50. This proves that there has been an increase in the value of children for cognitive development by 25.50.
