Development of Photographic Thematic Flashcards as a Learning Medium for Introducing Basic English Vocabulary to Kindergarten Students at Kiddos Preschool

This study aims to analyze needs, design a prototype, and test the feasibility of Photographic Thematic Flashcards as an alternative for introducing basic English vocabulary to Kindergarten A students at Kiddos Preschool. The study employed a Level 1 Research and Development (R&D) method based on the Borg and Gall model, as adapted by Sugiyono (2019), encompassing needs analysis, product design, and expert validation without a field trial. Data were collected through classroom observations, teacher interviews, curriculum analysis, and an expert validation questionnaire. Learning media previously used at the school, such as video presentations on television, have made a positive contribution to vocabulary introduction; therefore, a supplementary visual medium was developed in the form of 15 cm × 15 cm picture cards made of 310 gsm Art Carton with a glossy laminate and rounded corners, designed in alignment with the curriculum themes. Validation results from two experts yielded an average score of 71.5 in the “Good” category, with a feasibility percentage of 79.44%. Thus, the Photographic Thematic Flashcards were deemed academically valid and suitable for further development through field testing.
