The "Flashcard ก-ฮ" project was developed with the objective of transforming the challenge of learning Thai consonants into an opportunity for creating innovative and contemporary educational tools. The design emphasizes ease of recognition and usability, fostering positive interaction between parents and children. The flashcards were formulated through a comprehensive design process aimed at addressing essential learning challenges, such as the retention of consonants and the mitigation of common writing errors. The inclusion of illustrations and structured designs enhances the learning experience, making it both engaging and memorable. At BKKDW2025, visitors can explore the flashcards and learn about the design process behind them, highlighting the role of design in problem-solving and everyday learning.
