Eight deaf children in kindergarten to 3rd grade classes will be randomly selected for single case research. Their language skills will be monitored and assessed daily. Using a noncurrent multiple baseline design (Single Case Research Design or SCRD), Strategic and Interactive Signing Instruction (SISI) will be administered to two children in each of four classes.
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.

| Single Case Research Design: Phase 1 | Experimental | 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 Phase 1 participants in a class will begin receiving SISI while other children remain in the baseline for 3 to 9 weeks. |
|
| Single Case Research Design: Phase 2 | Experimental | 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, three weeks after Phase 1 participants have begun SISI, Phase 2 participants in a class will begin receiving SISI while other children remain in the baseline. |

| Single Case Research Design: Phase 3 | Experimental | 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. |

Under a data-sharing agreement that is in compliance with the internal policy at UTK, non-identifying data can be shared with other researchers for a minimum of 10 years on the University of Tennessee Research and Creative Exchange (TRACE). The raw data consists of videos of teachers, which will not be shared to maintain confidentiality. The processed data will be in the form of percentages for individual teachers across an academic year documented in a .csv file (Excel). Center for Open Science Foundation (OSF) is a free and open source project management tool that supports researchers throughout their entire project lifecycle. OSF also allows people to locate this data through project names, author names, and study keywords.
December, 2026 to December, 2036
Researchers may contact the principal investigator for additional supporting information not available on OSF.
