Enhancing Linguistic Ability to Speaking Impaired Learners Using Universal Design Framework: An Experimental Study

Abstract

Many students around the world struggle with speech impediment, a form of communication dysfunction. Because of this, it is crucial to provide effective teaching for students with speech impairments so that they can improve their communication abilities. This experimental study looks into how well the Universal Design for Learning (UDL) framework can help students with speech impairments develop their language skills. The study involved 112 participants aged 18 to 20 diagnosed with speech impairments. During the study, the participants were randomly divided into two groups: an experimental group n=56, which received speaking skills instruction using the UDL framework, and a control group n=56, which received traditional instruction. Participants from both groups will complete a pre-test to measure their baseline speaking skills. The experimental samples received instruction using UDL, while the control group was exposed to traditional methods. After the intervention, both groups completed a post-test to measure their speaking skills. Statistical methods such as ANOVA and t-tests were used to analyze the data collected. According to the results, the experimental group performed better on the post-test than the control group regarding speaking skills. Performance levels were higher among the experimental group than among the control group. This study proves that the UDL framework can effectively facilitate speaking skills for learners with speech impairments. The study suggests that the UDL framework can help educators deliver instruction accessible to all learners, including those with disabilities.
