Using Differentiation Techniques to Improve Speaking Skills in Mixed-Ability Classrooms

This article investigates the effectiveness of differentiation techniques in developing speaking skills among learners in mixed-ability English as a Foreign Language (EFL) classrooms. The study examines how differentiated instruction — including tiered speaking tasks, scaffolded activities, and flexible grouping — can respond to the diverse proficiency levels, learning styles, and confidence levels found in a single classroom. Drawing on theoretical frameworks by Tomlinson (2001), Vygotsky (1978), and Harmer (2007), the article argues that a uniform teaching approach fails to meet the individual needs of all learners, particularly during speaking activities where differences in fluency, accuracy, and anxiety become most visible. An experimental study was conducted at School 14 in Fergana with 6th and 7th grade learners divided into experimental and control groups. Findings demonstrate that learners in the experimental group — where differentiated instruction was applied — showed significantly greater improvement in speaking performance, motivation, and willingness to communicate compared to the control group. The article concludes that systematic use of differentiation techniques is both practical and necessary for inclusive, effective speaking instruction in mixed-ability secondary school classrooms.
