B.Tech Common Syllabus(1st Sem) Semester I HS it 01 ENGLISH FOR PROFESSIONAL COMMUNICAT ION' (Objective of the Course) To impart basic skills of Communication in English through intensive practice to the First Year UG Students of Engineering so as to enable them to function confidently & effectively in that Language in the Professional Sphere of their life. Desirol Entry Behaviour The student must have some basic command of English so that the Student must be able to: 1. Write reasonably & grammatically 2. Understand (if not use) at least some 2500 general purpose words of English 3. Use some 2000 (at least 1500) general-purpose words of English to express himself in writing & 1500 such words to talk about day-to-day events & experiences of life. 4. Understand slowly-delivered spoken material in Standard Indian English, and Teaching Method 5. Speak reasonably clearly (if not fluently) on routine matters with his fellow Students.. 1. The topics must be covered essentially through plenty of examples. Lecture Classes must be conducted as Lecture-cum-Tutorial Classes. 2. It is a course that aims to develop skills. It is, therefore, "Practical" in orientation. Plenty of exercises of various kinds must be done by the Students both inside & outside the Classroom. . 3. The Teacher must not depend on a single or a set of two to three Text Books. He must choose his materials from diverse sources. 4. Keeping in view the requirements of his Students, the Teacher may have to prepare some teaching & exerciss materials. 5.
