Project – Assistive Technology and Classroom Participation of Students with Hearing Impairment: A Study of Selected Special Schools in Lagos State

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Education is a fundamental means through which individuals develop knowledge, skills, social competence and capacities necessary for personal and societal development. The right to education applies equally to persons with disabilities, including students with hearing impairment, and requires educational systems to remove barriers that prevent meaningful participation in learning. The United Nations Convention on the Rights of Persons with Disabilities specifically recognises the right of persons with disabilities to inclusive, quality education and requires appropriate support, reasonable accommodation and individualised measures that facilitate effective participation in education. For students who are deaf or hard of hearing, the Convention further recognises the importance of appropriate communication modes, sign language, specialised educational materials and trained personnel. Thus, participation in education is not simply a matter of enrolling students with hearing impairment in schools but also ensuring that the classroom environment provides the communication and technological support necessary for them to participate effectively (United Nations, 2006).

Hearing impairment can create significant barriers to students’ access to classroom communication because much of conventional teaching depends on spoken explanations, oral instructions, classroom discussions and auditory information. Students with hearing impairment may therefore experience difficulties following teacher explanations, participating in discussions, responding to questions, interacting with peers and receiving information presented primarily through speech. The World Health Organization emphasises that hearing loss can affect communication, education and social participation and that rehabilitation may include hearing technologies, hearing assistive technology, captioning, communication support and sign-language services. For children and adolescents, early and appropriate intervention is particularly important because unaddressed hearing loss can affect educational development and participation in school and community life (World Health Organization [WHO], 2024, 2026).

Assistive technology has consequently become an important component of disability-inclusive education. Assistive technology refers broadly to products, devices, systems and related services that maintain or improve an individual’s functioning and participation. In the case of students with hearing impairment, relevant technologies may include hearing aids, frequency-modulation systems, classroom amplification systems, captioning tools, speech-to-text applications, alerting devices, digital learning applications, video materials with captions and technologies that facilitate sign-language communication. The World Health Organization notes that assistive technology can improve functioning, communication, inclusion and participation, while a systematic review by Fernández-Batanero et al. (2022) found that assistive technologies can increase accessibility and inclusion for students with disabilities, although barriers such as inadequate teacher preparation, limited information and accessibility constraints can reduce their effectiveness.

The relevance of assistive technology to students with hearing impairment extends beyond merely helping students hear classroom instruction. Technology can provide alternative channels through which information is received, processed and communicated, thereby creating opportunities for students to participate more actively in classroom activities. A systematic review by Rodríguez-Correa et al. (2023) identified several categories of technologies designed to support Deaf people’s communication, including sign-language recognition and translation technologies, sign-language teaching tools, automatic caption-generation systems, online educational resources and text-based technologies. Such technologies can reduce communication barriers between Deaf students and hearing teachers or peers and may facilitate educational, social and collaborative participation. The authors nevertheless emphasised that technology needs to be designed and implemented with attention to the linguistic and cultural characteristics of Deaf communities rather than assuming that a single technological solution is appropriate for all learners (Rodríguez-Correa et al., 2023).

Classroom participation is an important dimension of educational inclusion because students need opportunities not only to be physically present in school but also to engage behaviourally, cognitively, emotionally and socially in classroom activities. For students with hearing impairment, participation may involve listening or accessing visual information, answering questions, contributing to discussions, interacting with teachers, collaborating with peers, completing classroom tasks and demonstrating understanding. Evidence indicates that communication barriers, classroom noise, complex instructions and inadequate technological support can make classroom participation more difficult for students with hearing loss. A recent systematic review of deaf children’s experiences found that hearing demands in school can be substantial and that background noise, complex oral instructions and listening fatigue may reduce concentration and participation; the review also reported that some students rely heavily on hearing devices and additional visual or communication support in school environments (Journal of Deaf Studies and Deaf Education, 2025).

The Nigerian context makes the relationship between assistive technology and classroom participation particularly important because the availability, accessibility and utilisation of specialised educational technologies remain significant concerns. Recent Nigerian research has identified barriers such as inadequate infrastructure, insufficient teacher training, limited access to devices and weak integration of technology into educational practice. In research involving Nigerian schools, teachers and students expressed positive perceptions of the potential of digital learning applications to improve engagement, literacy and independent learning among students with hearing impairment, despite very low reported levels of actual use. Similarly, Ogunwale, Okoro and Ibitoye (2025), in a study of secondary-school teachers in Ibadan, found a significant positive relationship between assistive technology and inclusive classroom management and reported that the availability of assistive technology significantly influenced students’ academic engagement. These findings suggest that the availability and effective use of assistive technology may be important conditions for improving classroom experiences among students with hearing impairment in Nigeria (Ogunwale, Okoro, & Ibitoye, 2025; Nigerian Online Journal of Educational Sciences and Technology [NOJEST], 2026).

Lagos State provides a particularly relevant setting for examining this issue because the state has established special and inclusive schools serving learners with disabilities, including students with hearing impairment. The Lagos Eko Secondary Education Project identified five special schools and seven inclusive schools and reported support for specialised educational materials, software, teacher training and other resources intended to facilitate teaching and learning for students with disabilities. Earlier research conducted in Lagos State also examined the audiological profile of hearing-impaired pupils enrolled in designated inclusive schools, demonstrating that hearing impairment is an established educational concern within the state’s school system. More broadly, UNICEF emphasises that children with disabilities frequently encounter barriers to education and that assistive technologies, including hearing aids and other communication-support technologies, can help children with disabilities participate in learning and social life (Lagos Eko Project, 2012; Asoegwu, Ogban, & Nwawolo, 2019; UNICEF, 2024).

Despite the increasing recognition of assistive technology as an instrument of inclusive education, access to a device does not automatically guarantee meaningful classroom participation. The effectiveness of assistive technology may depend on availability, appropriateness, reliability, teacher competence, student familiarity, maintenance, electricity and infrastructure, communication practices and the extent to which technology is integrated into classroom instruction. Evidence from Nigerian research indicates that inadequate teacher training and infrastructure can constrain the use of assistive technology, while international evidence similarly identifies teacher preparation and accessibility as important barriers. Therefore, examining the relationship between assistive technology and classroom participation requires attention not only to whether technologies are available but also to their use in actual teaching and learning situations. This study consequently focuses on selected special schools in Lagos State to assess how assistive technologies such as hearing devices, captioning and visual communication technologies, digital learning technologies, and classroom communication systems relate to the classroom participation of students with hearing impairment (Fernández-Batanero et al., 2022; Ogunwale et al., 2025; WHO, 2024).

1.2 Statement of the Problem

Students with hearing impairment have the same right to education and participation as other learners, but their ability to participate meaningfully in classroom activities can be affected by communication barriers. Traditional classroom instruction frequently relies on spoken explanations, oral questioning, auditory instructions and spontaneous teacher–student interaction. Where students cannot adequately access such information, they may experience difficulties following lessons, answering questions, contributing to discussions and interacting with classmates. The United Nations recognises the need for reasonable accommodation, individualised support and appropriate communication modes for students with disabilities, while the WHO identifies timely hearing interventions and assistive technologies as important means of supporting educational participation among children with hearing loss (United Nations, 2006; WHO, 2026).

A second problem concerns the availability and utilisation of appropriate assistive technologies in educational settings. Although technologies such as hearing aids, captioning systems, frequency-modulation systems, digital applications and other communication-support devices can potentially reduce barriers, access to these technologies remains uneven. A systematic review of assistive technology for students with disabilities identified lack of teacher education, limited information and accessibility constraints as significant barriers to effective technology use. Recent Nigerian evidence also reports inadequate infrastructure, limited devices and insufficient teacher training as obstacles to integrating digital learning applications for students with hearing impairment. Thus, the mere presence of assistive technology in a school may not necessarily translate into effective classroom use or improved participation (Fernández-Batanero et al., 2022; NOJEST, 2026).

Another problem is that students with hearing impairment may continue to experience low levels of classroom engagement even where some forms of technological or educational support are available. Classroom participation involves more than hearing the teacher; it includes asking and answering questions, contributing to discussions, working with peers, completing learning tasks and interacting with teachers. Research among students with hearing impairment has demonstrated that targeted educational interventions can improve school engagement, while research on hearing experiences indicates that background noise, listening effort, complex instructions and inadequate support can restrict participation. These findings raise the question of whether the assistive technologies available in special schools are sufficiently appropriate and effectively utilised to facilitate active classroom participation (Adediran et al., 2020; Journal of Deaf Studies and Deaf Education, 2025).

Finally, there is a contextual research gap concerning selected special schools in Lagos State. Existing research has examined hearing impairment and inclusive education in Lagos, while other Nigerian studies have investigated assistive technology and students with hearing impairment in other locations such as Ibadan. Ogunwale et al. (2025), for example, found significant relationships between assistive technology, inclusive classroom management and students’ academic engagement in Ibadan, while Asoegwu et al. (2019) documented the audiological characteristics of hearing-impaired pupils in Lagos inclusive schools. However, there remains a need for more specific evidence on how different forms of assistive technology influence the classroom participation of students with hearing impairment in selected special schools in Lagos State. The absence of such context-specific evidence makes it difficult to determine which technological supports are most relevant to students’ participation in classroom activities. This study therefore seeks to examine the relationship between assistive technology and classroom participation of students with hearing impairment in selected special schools in Lagos State (Asoegwu et al., 2019; Ogunwale et al., 2025).

1.3 Objectives of the Study

The general objective of this study is to examine the relationship between assistive technology and classroom participation of students with hearing impairment in selected special schools in Lagos State.

The specific objectives are to:

1. examine the influence of hearing assistive devices on the classroom participation of students with hearing impairment in selected special schools in Lagos State;
2. determine the influence of captioning and visual communication technologies on the classroom participation of students with hearing impairment in selected special schools in Lagos State;
3. assess the influence of digital learning and communication technologies on the classroom participation of students with hearing impairment in selected special schools in Lagos State; and
4. examine the influence of classroom communication support technologies on the classroom participation of students with hearing impairment in selected special schools in Lagos State.

1.4 Research Questions

The following research questions will guide the study:

1. To what extent do hearing assistive devices influence the classroom participation of students with hearing impairment in selected special schools in Lagos State?
2. To what extent do captioning and visual communication technologies influence the classroom participation of students with hearing impairment in selected special schools in Lagos State?
3. What influence do digital learning and communication technologies have on the classroom participation of students with hearing impairment in selected special schools in Lagos State?
4. To what extent do classroom communication support technologies influence the classroom participation of students with hearing impairment in selected special schools in Lagos State?

1.5 Research Hypothesis

The following null hypothesis will be tested at the 0.05 level of significance:

H₀: There is no significant relationship between assistive technology and classroom participation of students with hearing impairment in selected special schools in Lagos State.

1.6 Significance of the Study

The study will be significant to the Lagos State Ministry of Education and other education authorities responsible for special and inclusive education. The findings will provide empirical information on the extent to which assistive technologies contribute to the classroom participation of students with hearing impairment. This may assist policymakers in planning the procurement, distribution, maintenance and effective utilisation of appropriate assistive technologies.

The study will also be useful to school administrators and principals of special schools. The findings may help administrators identify technological resources that can facilitate communication and participation among students with hearing impairment. The study may also encourage school administrators to consider teacher training, maintenance arrangements and appropriate classroom practices when implementing assistive-technology initiatives.

The study will benefit teachers of students with hearing impairment by identifying technological resources that may support classroom communication and student engagement. The findings may encourage teachers to integrate hearing devices, captioning, visual communication tools and digital resources into their instructional practices in ways that complement sign language and other established communication approaches.

The study will be beneficial to students with hearing impairment because improved understanding of the role of assistive technology may contribute to better classroom participation. Where appropriate technologies are available and effectively used, students may have greater opportunities to access instructional information, respond to teachers, participate in classroom discussions, collaborate with peers and complete learning activities.

The study will also be useful to parents and guardians of students with hearing impairment. It may provide information about the educational value of appropriate assistive technologies and reinforce the importance of supporting students’ access to and proper use of relevant hearing and communication devices.

The study will be significant to special educators, audiologists, speech and language professionals and educational technology practitioners. The findings may provide evidence that can support collaboration between education and rehabilitation professionals in identifying appropriate technological interventions for students with hearing impairment.

Finally, the study will contribute to academic literature on assistive technology and special education in Nigeria. By focusing on selected special schools in Lagos State, it will provide context-specific evidence that complements existing international research and Nigerian studies conducted in other educational settings.

1.7 Scope of the Study

The study focuses on Assistive Technology and Classroom Participation of Students with Hearing Impairment, with particular reference to selected special schools in Lagos State.

The content scope covers four major dimensions of assistive technology: hearing assistive devices, captioning and visual communication technologies, digital learning and communication technologies, and classroom communication support technologies. Classroom participation will be examined in relation to students’ ability to access classroom instruction, respond to teachers, participate in discussions, interact with peers, engage in learning activities and complete classroom tasks.

The geographical scope of the study is limited to selected special schools in Lagos State, Nigeria that provide educational services to students with hearing impairment. The study does not cover students with visual, physical, intellectual or other forms of disabilities except where such disabilities occur alongside hearing impairment among the selected participants.
