Examining the Role of Invisible Disabilities in Shaping Pedagogical Approaches for Inclusive Classrooms

Abstract

This study analyzed how invisible disabilities influenced student learning experiences and teaching practices in inclusive classrooms across diverse school types (public, private, urban, and rural) in Kenya. The study focused on student perspectives and the diverse needs of these children to fill gaps in understanding and implementing inclusive pedagogies. Drawing from theoretical frameworks such as Universal Design for Learning (UDL) and Differentiated Instruction (DI), this research employed a sequential explanatory mixed-methods design. The target population comprised 16 schools from four counties (Nairobi, Kiambu, Nakuru, and Mombasa), with a total of 10,000 students and 565 teachers. A sample size of 196 participants (81 teachers and 115 students) was calculated using Fisher's formula with a 7% margin of error. The researcher visited 11 schools and successfully collected data from 9 schools. Data collection achieved a 72.4% response rate with 142 participants (71 teachers and 71 students) across 9 schools. For the qualitative phase, purposive sampling selected 9 school administrators out of 16 targeted for in-depth interviews, achieving a 56.3% response rate. Students reported significant learning challenges, with 73.2% experiencing difficulties across multiple subjects and written expression presenting the greatest challenge (M=2.93). Students demonstrated clear preferences for visual learning strategies (67.6% identifying pictures and visual aids as most helpful) and identified classroom noise as the primary learning barrier (63.4%). Teachers demonstrated strong philosophical commitment to inclusive education (90.1% believing students with invisible disabilities could achieve success) but reported substantial knowledge gaps, with only 40.8% rating their understanding as good or excellent. Teachers perceived inclusive practices as most effective in social-emotional development (M=4.20) compared to academic achievement (M=3.99). Large class sizes represented the most severe implementation barrier (71.8% significant/major), with public schools facing significantly more constraints than private schools (78.2% vs. 56.3%). Students confirmed implementation challenges through limited access to accommodation, with only 32.4% receiving extended time for tests and 16.9% accessing special materials. The study revealed that while teachers possessed strong commitment to inclusive principles, significant gaps existed between philosophical beliefs and practical implementation capacity. Student perspectives validated teacherreported barriers while demonstrating remarkable consistency between learning preferences and evidence-based accommodation requests. Structural barriers, particularly large class sizes and resource limitations, fundamentally constrained inclusive practice delivery, with public schools experiencing more severe challenges than private institutions. Schools should establish systematic professional development programs targeting invisible disability identification and intervention strategies, implement resource allocation plans for specialized materials and reduced class sizes, and develop family engagement initiatives to build community understanding. Policy makers should create national inclusive education standards, reform teacher preparation programs, and establish funding mechanisms that account for inclusive education costs while developing accommodation policies for national assessments.
