Abstract
This article examines the role, functions, and principles of visual technologies in the speech preparation of preschool children, particularly those aged 6–7, for school education. Visualization is described as a key tool for transforming complex information into clear and memorable images, promoting the development of speech, memory, thinking, and attention. The study analyzes the main types of visual technologies, their psychological and pedagogical foundations, their impact on children’s cognitive and speech development. The article also highlights pedagogical principles for applying visual technologies, including consideration of age characteristics, interactivity, systematicity, and associativity.
