Mapping Interlanguage through Error Analysis: A PEN Framework for Pedagogical Intervention in Rural ESL Contexts

Within contemporary English Language Teaching, narrowing the divide between learners' first language and the target language is essential for fostering communicative competence beyond rote grammatical instruction. This study quantitatively investigates persistent grammatical error patterns in the essays written by rural ESL learners in Gujarat, India and proposes the Productive Failure–Error Analysis–Noticing (PEN) framework as a conceptual pedagogical model emerging from empirical evidence. Grounded in Interlanguage Theory and Error Analysis, the study analyses a corpus of 423 descriptive essays produced by Class XII students from nine Jawahar Navodaya Vidyalayas in Gujarat, India, with a stratified sample of 127 essays examined in detail. Seventeen categories of morpho-syntactic and orthographic errors were identified, with spelling, articles, noun usage, and lexical choice structures emerging as the most frequent domains. Statistical analyses reveal significant variations across gender and academic streams, indicating patterned interlanguage development influenced by interlingual, intralingual, and overgeneralization factors. Findings are systematically mapped onto the PEN framework, establishing a clear connection between empirical analysis and pedagogical intervention. Building on these findings, the study synthesizes insights from errorful learning and productive failure, operationalized through Written Corrective Feedback, and culminates in Schmidt's Noticing Hypothesis as the key learning trigger. The resulting PEN framework offers a structured, feedback-driven model that reconceptualizes learner errors as productive resources for language development. The study contributes to SLA and ELT by advancing a theoretically integrated and pedagogically actionable model for rural ESL contexts.
