Development of Early Braille Reading Skills Teaching Module for Preschoolers: Fuzzy Delphi Method

Abstract

The Fuzzy Delphi Method creates an early braille reading skills module for vision-impaired preschoolers. The project seeks a consensus-based, holistic solution to declining rates and technological integration in early braille literacy. Based on the Model Bottom-Up, 11 experts assessed six constructs. For analysis, FUDELO 1.0 and a 7-point Fuzzy scale were employed. Constructs provide 86% expert support for all proposed features. The study supports Sustainable Development Goal 4's inclusive education goals with evidence-based special education. Future research should focus on module adaptability, longitudinal effect studies, and practical implementation in different educational contexts and learner needs.
