Effectiveness of Assistive Technology in Special Education for Learners with Hearing Loss in Wajir Kenya

Abstract

This study investigated the effectiveness of assistive technology in special education for learners with hearing loss at Wajir Secondary School for the Deaf, Kenya. The research addressed persistent challenges in inclusive education, where learners with hearing impairments faced barriers to accessing quality education despite technological advances and policy frameworks supporting inclusive practices. The study aimed to determine the types of assistive technology used, examine associated benefits, identify implementation challenges, and evaluate the impact on academic performance among learners with hearing loss. The research was grounded in the Universal Design for Learning framework, the Social Model of Disability, and the Technology Acceptance Model, providing theoretical foundations for understanding how assistive technologies enhanced educational accessibility and participation. The study was conducted at Wajir Secondary School for the Deaf in Wajir County, Kenya, targeting Forms 3 and 4 students with hearing loss, their teachers, and parents. A mixed-methods design was employed, combining quantitative and qualitative approaches to gather comprehensive data. The population included 35 learners with hearing loss, 10 teachers, and 5 parents. Data collection utilized structured questionnaires, semi-structured interviews, and classroom observations. Quantitative data were analyzed using descriptive statistics and chi-square tests via SPSS, while qualitative data underwent thematic analysis using NVivo software. The findings revealed that hearing aids (85.7%), visual learning tools (57.1%), and speech-to-text software (34.3%) were the most commonly used assistive technologies. Key benefits included enhanced communication with teachers (71.4%), improved access to learning materials (62.9%), and increased classroom participation (57.1%). Teachers reported improved student engagement (80%) and better academic performance (70%). However, significant challenges emerged, including frequent device breakdowns, inadequate technical support, limited teacher training, and insufficient funding for device maintenance.A statistically significant association (χ² = 6.12, p = 0.047) was found between frequent assistive technology use and perceived academic improvement, with 85.7% of learners reporting enhanced academic performance. Qualitative findings confirmed improvements in test scores, classroom participation, and social integration. The study demonstrated that while assistive technology showed considerable promise in enhancing educational outcomes for learners with hearing loss in resource-constrained environments, success depended critically on sustained institutional support, comprehensive teacher training, reliable technical maintenance, and adequate funding mechanisms to ensure long-term sustainability and effectiveness.
