The innovative aspects of this study lie in the use of hyperfocus as a strategic tool to enhance student learning and engagement, the use of TEACCH principles, and the use of the phonics method as a literacy model. The tool combines playful elements, specific educational goals, and reading teaching methods based on the latest studies on verbal language, especially in the areas of psycholinguistics and neuroscience. The prototype of this application was tested by special education professionals, and the test results indicated the need for a redistribution of levels and content. The modifications were made during the implementation phase, and the platform was tested with special education professionals from the early years of elementary school and with children with ASD aged 6 to 12, in the first grades of elementary school. The results showed high student interest in the platform, as well as strong adherence to the most current teaching methods for children with ASD.pt-BRAttribution 3.0 BrazilSistemas de InformaçãoTranstorno do Espectro Autista (TEA)Jogos Sérios (JS) – AlfabetizaçãoEducação especialAutismoAutismSerious gamesLetramundo: um jogo sério para alfabetização de crianças com Transtorno do Espectro Autista (TEA) em ambiente escolarTrabalho de Conclusão de CursoCIENCIAS EXATAS E DA TERRA:CIENCIA DA COMPUTACAO:METODOLOGIA E TECNICAS DA COMPUTACAO:SISTEMAS DE INFORMACAO
