To raise awareness of Developmental Language Disorder (DLD) in Hong Kong, our Lab Director Dr. Anita Wong and three speech-language therapists, Ms. Rosanna Lee, Ms. Cecilia Au and Ms. Christine Au spoke to 250 teachers in 26 Po Leung Kuk Kindergartens on preschool language development and DLD on March 9, 2019. Through viewing video-clips of children with DLD, teachers learned about signs of the disorder. Teachers also learned how to provide a high quality interactive language environment for children in their classrooms.
