Mitigating Academic Decline in English Language Skills through Aspectual Diversification and Curriculum–Practice Convergence: A Multi-Theoretical Perspective Based on PTAPD, ADLL, and CPCT
Abstract
Persistent decline in students’ academic performance in English Language across Nigerian secondary schools has raised critical concerns for educators, curriculum planners, and policymakers. This paper synthesizes three contemporary theoretical contributions: Philip’s Theory of Academic Performance Decline (PTAPD), the Aspectual Diversification in Language Learning Theory (ADLL), and the Curriculum–Practice Convergence Theory (CPCT) to construct a multi-theoretical lens for diagnosing and addressing the crisis. Drawing from national examination trends, curriculum studies, and second language acquisition literature, the paper argues that English Language underachievement is not merely a product of poor instructional quality but a systemic interplay of cognitive overload, undiversified pedagogical practices, and longstanding gaps between prescribed curriculum expectations and classroom realities. PTAPD provides a diagnostic framework explaining the cognitive, structural, and motivational triggers of learning decline; ADLL advances an innovative pedagogical model that promotes multi-teacher, aspect-based instruction for grammar, comprehension, writing, oral communication, and literature; and CPCT highlights the pressing need to realign curriculum documents with feasible classroom enactment. Through a conceptual synthesis of these theories, the paper proposes an Expanded Academic Recovery (EAR) Model that integrates instructional diversification, curriculum streamlining, teacher re-specialisation, and assessment reform as pathways toward mitigating English Language performance decline. This paper contributes a theoretically grounded and practice-oriented agenda for strengthening English Language education in Nigerian secondary schools and provides a foundation for future empirical research in curriculum innovation, language pedagogy, and educational policy reform.
