What is the purpose of this trial?

This trial tests a new method of teaching sign language, called Strategic and Interactive Signing Instruction (SISI), to help deaf children in prekindergarten through 3rd grade improve their sign language skills. Teachers will be divided into two groups: one will use the SISI method, while the other will continue with their usual techniques. The goal is to determine if SISI can better support the language development of these children. Deaf children in prekindergarten to 3rd grade and their teachers in deaf education programs may be suitable for this trial. As an unphased trial, this study offers a unique opportunity to contribute to innovative educational methods that could enhance language skills for young deaf children.

Will I have to stop taking my current medications?

The trial does not specify whether participants need to stop taking their current medications.

What prior data suggests that this method is safe for supporting sign language development in deaf children?

Research has shown that Strategic and Interactive Signing Instruction (SISI) can enhance sign language skills, potentially improving reading and health outcomes for deaf children. While specific safety data for this type of sign language teaching is not available, the trial does not involve testing a drug or medical device, so physical safety concerns remain minimal. The study focuses on learning and educational growth, making it a low-risk activity. Participants can feel assured that this study involves learning and support without any known negative effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Strategic and Interactive Signing Instruction (SISI) because it offers a fresh approach to teaching sign language to deaf children. Unlike traditional methods, which may rely heavily on standard teaching practices, SISI emphasizes interactive and strategic instruction tailored to enhance children's sign language skills more effectively. This innovative approach could lead to better language development outcomes, providing educators and students with a more engaging and potentially more effective learning experience.

What evidence suggests that Strategic and Interactive Signing Instruction is effective for sign language development in deaf children?

This trial will compare Strategic and Interactive Signing Instruction (SISI) with standard teaching methods. Studies have shown that learning complex sign language skills can improve reading and writing abilities and may even lead to better health. SISI resembles techniques that have successfully helped deaf and hard-of-hearing students enhance their writing and language skills. Research on a similar program, Strategic and Interactive Writing Instruction (SIWI), showed it effectively enhanced writing skills like storytelling and persuasive writing. These positive results suggest that SISI could help develop sign language skills in deaf children. ^{1 2 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Strategic and Interactive Signing Instruction

Trial Overview

The study tests a new method called Strategic and Interactive Signing Instruction (SISI) against the standard 'business-as-usual' teaching methods. Teachers will be split into two groups: one receiving SISI training and the other continuing with current practices.

How Is the Trial Designed?

Group I: RCT - Experimental Experimental Treatment 1 Intervention

This RCT study involves teachers divided into an experimental group and a control group. Teachers in the experimental group will receive SISI training to support the sign language development of deaf children, while those in the control group will continue with "business-as-usual" teaching methods. Pre- and post-assessments will be conducted for all deaf children at the beginning and end of the school year.

Group II: Quasi-Experimental Study - Control Placebo Group 1 Intervention

This quasi-experimental study involves teachers divided into an experimental group and a control group. Teachers in the experimental group will receive SISI training to support the sign language development of deaf children, while those in the control group will continue with "business-as-usual" teaching methods. Pre- and post-assessments will be conducted for all deaf children at the beginning and end of the school year.

In a study involving 224 adults with typical development, the distinct Key Word Signing (KWS) lexicon (SMOG) was found to have higher iconicity compared to Flemish Sign Language (FSL), making it potentially more accessible for individuals with communication difficulties.

The results suggest that using a separate sign lexicon like SMOG may be beneficial for enhancing communication, especially for those with intellectual disabilities, although considerations for availability and inclusion are also important.

Strategic and Interactive Writing Instruction (SIWI) significantly improved the writing skills of deaf and hard of hearing elementary students, particularly in information reports and persuasive writing, as shown by five case studies.

A larger group study with 31 students also demonstrated statistically significant improvements across all writing genres, indicating that SIWI is an effective instructional method for enhancing written expression in this population.

Younger deaf signing children (aged 4-7) showed more frequent omissions of signs compared to older children (aged 8-12) and deaf signing adults, indicating that age impacts the mastery of Italian Sign Language (LIS).

The study found that non-manual components (like facial expressions) used alongside manual signs are particularly challenging for younger children to learn, highlighting specific areas where linguistic skills develop more slowly.
