Enhancing Workplace English Communication: A Comparative Study of Technology-Assisted and Task-Based Linguistics Models in Delhi Organizations

Abstract

Effective workplace communication is vital in multilingual, multicultural contexts like Delhi’s immigrant workforce. This study compared Google Classroom–based Digital Didactic Units (DDU) and Task-Based Speaking Clubs in enhancing English skills among 42 immigrant employees from Nepal and Myanmar. Using a mixed-methods quasi-experimental design with diagnostic tests, final tests, anxiety scales, and focus groups, results showed significant gains: DDU scores rose from 27% to 75%, and Speaking Club scores from 42% to 78% (p < .001). Anxiety decreased from 4.1 to 2.3 (α = .92). Findings highlight ICT-supported and task-based approaches as effective for communication, confidence, and workplace inclusion.
