10144EC610 COMMUNICATION SKILLS LAB - II

(Common to all B.E. / B.Tech.)

(To be conducted as a Practical Paper by the Department of English for 3 hrs per week)

OBJECTIVES

�� To equip the learners face the linguistic demands of post-degree entrance

examinations

�� To improve the IV level active vocabulary

�� To reactivate and reinforce the language functions introduced in earlier papers

�� To help the learner infer message from non-verbal cues and speak fluently on them

�� To help the learners inculcate the micro skills of debating on a subject

�� To motivate the learners read English dailies and react critically to news items

�� To help the learners acquire the skills related to organization of thoughts while

writing articles.

COURSE CONTENT

A) Target words (20 hrs)

((Words D+ to Z from Barron’s GRE Test)

B) Writing articles on media-based themes (10 hrs)

C) Debate (8 hrs)

D) Channel conversion (Speaking on Non-Verbal representations) (7 hrs)

RECORD LAY OUT

Every student has to maintain record in which he/she has to incorporate the following

details.

Part I: Use of Vocabulary

�� 10 assignments (each 20 words) using the target words in sentences of their own.

�� Separate word lists to be allotted to students so that all the words in the target

vocabulary are covered.

�� Assignments to be written in the record notebook only after the approval of the

professor in charge.

Part II: Article based on newspaper reading

�� One article (750 words) based on any theme emerging out of the news items.

(According to the methodology suggested)

�� It should be written only on the odd pages.

�� News items (at least 5) should be collected from English dailies and pasted on the

even pages.

Part III: Internal Question Papers on Target Vocabulary Testing & Coding sheets

�� Six Question papers to be pasted ( 2 for synonyms, 2 for antonyms and 2 for

sentence completion)

�� The corrected coding sheets (6) to be pasted.

The record should be duly signed by the Course Teacher and submitted to the External

Examiner for verification during the semester practical.

MODE OF EVALUATION

Internal Assessment (20 marks) (10 marks for the Record and 10 marks for the six tests

on Target Vocabulary)

External Assessment (100 marks-to be converted to 80 marks)

The external practical * will consist of two segments (a) Written Test and (b) Testing

Speaking

Written Test (1 hr)

a) Testing Target Vocabulary (40 objective type items – 15 synonyms, 15 antonyms

and 10 sentence completion) (40 marks)

b) Writing articles on the theme emerging from the given newspaper, items given (5

newspaper items based on a single theme will be given) (20 marks)

Testing Speaking (3 + 3 minutes)

a) Debate (Each student will be required to speak for three minutes for or against a

given topic) (20 marks)

b) Speaking on the given diagram / chart / table (20 marks)

(*Every learner will be assessed with a different set of question which he / she will

choose a random)
