The Effectiveness of Differentiated Instruction in Developing English Reading Skills for Vocational School Students in Jinan, China

Abstract

In the context of China’s vocational education, English reading competence is crucial for accessing technical materials, safety protocols, and digital resources. However, students exhibit wide disparities in proficiency, motivation, and learning needs, making traditional “one-size-fits-all” instruction inadequate. This study investigates the effectiveness of Differentiated Instruction (DI) in enhancing English reading skills among first-year vocational students in Jinan, China. Employing a mixed-methods design, quantitative data from pre- and post-tests were combined with qualitative insights from semi-structured interviews to capture both performance outcomes and learner experiences. Results indicate that DI significantly improves reading comprehension compared to traditional instruction, with low- and medium-proficiency students showing the greatest gains. High-proficiency students achieved modest improvements, highlighting the need for upward differentiation. Qualitative findings reveal that appropriately leveled tasks, scaffolded support, and collaborative learning enhanced confidence, motivation, and engagement across proficiency levels. The study demonstrates that DI is not merely a remediation tool but a comprehensive instructional approach addressing cognitive, motivational, and social dimensions of learning. Implications include the importance of teacher training, tiered materials, and flexible grouping to foster equitable and effective vocational English education. Limitations and directions for future research, including long-term retention and skill transfer, are discussed.
