Single Case Research Design: Deaf Children's Language Outcomes

A randomized selection method will be employed to select deaf children to participate in single case research. Two children will be selected from each age group between 5 and 10, making a total of eight students. Their language skills will be closely monitored and evaluated over the course of the year. Following the noncurrent multiple baseline design, in succession across 8 child participants in 4 classes, 2 SCRD participants in a class will begin receiving SISI while other children remain in the baseline for 3 weeks. Brainstorming occurs on Monday and the final sign language composition is shared on Friday. At the end of each day's intervention, child participants will independently narrate their expressed message recorded on videos. A score of 1 (applied correctly), 0.5 (applied but incorrectly), or 0 (omitted) will be given to their inclusion of target sign language skills, which is converted into percentages. If a child receives 100% on their target SL skill for 3 consecutive days (3 data points), Teacher 1 will select a new sign language skill to target. If the child receives 0% or 50% on their target sign language skill, Teacher 1 continues to focus on the same sign language skill.
