The course is designed to train students in receptive (listening and reading) as well as productive and
interactive (speaking and writing) skills by incorporating a comprehensive, coherent and integrated
approach that improves the learners' ability to effectively use English language in academic/
workplace contexts. The shift is from learning about the language to using the language. On
successful completion of the compulsory English language course/s in B.Tech., learners would be
confident of appearing for international language qualification/proficiency tests such as IELTS,
TOEFL, or BEC, besides being able to express themselves clearly in speech and competently handle
the writing tasks and verbal ability component of campus placement tests. Activity based teaching-
learning methods would be adopted to ensure that learners would engage in actual use of language
both in the classroom and laboratory sessions.
Course Objectives
Facilitate effective listening skills for better comprehension of academic lectures and English
spoken by native speakers
Focus on appropriate reading strategies for comprehension of various academic texts and
authentic materials
Help improve speaking skills through participation in activities such as role plays,
discussions and structured talks/oral presentations
Impart effective strategies for good writing and demonstrate the same in summarizing,
writing well organized essays, record and report useful information
Provide knowledge of grammatical structures and vocabulary and encourage their appropriate
use in speech and writing
Learning Outcomes
At the end of the module, the learners will be able to
understand social or transactional dialogues spoken by native speakers of English and
identify the context, topic, and pieces of specific information
