Boostering Children’s Vocabulary by Using Integrated Thematical Textbook in Early Childhood Education (ECE)

Background/purpose. Kindergarteners' vocabulary deficiencies are caused by a lack of high-quality textbooks. The survey results demonstrated that children's learned language might be forgotten after a few days. The researchers conducted a study to identify and assess the standard of English textbooks already in use and to create textbooks that should be used in Kindergarten (TK) Aisyiyah Surakarta to address this issue. Materials/methods. Design-based research (DBR) was used in this study. The research process uses two stages: the development stage and the analysis stage of real-world problems. Results. The first findings indicated that there were benefits and drawbacks to the previously employed textbooks. The second stage of book production involves keeping the positive aspects of the first book, reducing or even getting rid of its negative aspects, and adding fresh, researcher-initiated features. These fresh components have been adjusted for the cognitive viewpoint. Conclusion. It is found that conversations and focus groups with instructors and academics as well as expert reviews went into creating this textbook prototype. Following the discussion and FGD, the textbook will be prepared for the TK Aisyiyah Surakarta test.
