(In general, wherever it is not indicated, one period each from any three subjects in
third and fourth semesters is to be set apart for ISAP.)
INFORMATION SEARCH ANALYSIS AND PRESENTATION SKILLS
DEVELOPMENT
IInnttrroodduucctt iioonn The average Engineer walking out of education institution is surprised by the amount of non-technical work he or she faces in the real world(by the amount of personal contact, the number of phone calls, meetings, reports and presentation etc). Further many cannot find appropriate jobs, because of the lack of these skills. The problem aggravates in the case of diploma pass outs who are supposed to have interactions with different cadres in an industrial environment. The time allotted for ISAP skills development are to be utilized to provide a slice of practical training in a form that may be used in a class room setting. This is not to be taught in a conventional manner. Here the emphasis will shift from teacher oriented methods to students oriented methods. While the information – skills acquired by all students will be same, the actual methods & techniques used by each student will vary according to his or her initiative, enthusiasm, effort taken etc. These hours are to be taken as a supplement to the theory classes. Students will acquire ISAP skills based on the fundamental knowledge he/she has acquired from the theory sessions.
Objectives
Educational researchers have found that 17 year olds, in a single academic year, learn about 200 to 300 new words, in a university environment. However, during the same period they acquire around 4000 words in their informal home and play environment. That is learning is higher in an informal environment than in an academic one designed specifically for that purpose. The primary objective here is to simulate the informal learning environment. Student is provided an ideal opportunity to acquire skills in learning to learn which is essential for the professional growth. This will inculcate information skills in the students. These skills will be a life long asset to him or her in fact they grow with age.
75
Oral and written communication skills are of at most importance to any engineer for a positive professional growth. Emphasis is given for this aspect also.
Activities
A. PART ONE. Write articles on various technical areas and basic research papers. Students can identify simple projects individually or groups of not more than 4 any technical area. Emphasis here is on the acquisition of ISAP skills.
Source of Information
a. People b. Print media – Magazines, News papers, Journals, Vendors catalogues etc. c. Electronic information – CD ROM, Usage of internet – User news groups,
WWW.
B. PART TWO
Transparency based Presentation
1. Preparation 1.1 Audience Analysis. 1.2 Information Gathering. 1.3 Transparency design using Power Point/Presentation software. 1.4 Production of transparency for OHP.
2. Delivery
Sample Projects
1. Prepare and deliver transparency based presentations on the topics, a. Technicians are not properly appreciated in the society. b. Engineers do not know about non technical topics. c. Lay people do not know enough about technical topics. d. India’s products are not competitive in international markets as its quality
is not good. e. India’s software professionals are paid too much.
2. Prepare transparency based presentation for the opposite side of the issue you choose in project 1.
3. Prepare and deliver a brief autobiographical presentation. 4. Prepare and deliver a sales promotional presentation (Example – Washing
machine, Computer , Air conditioner, Microwave oven or other items related to your branch of study)
76
5. Prepare and deliver a brief sales promotional presentation on a service (Example- Insurance Policy, Credit cards etc)
6. Prepare and deliver a technical presentation before lay audience (Example – Use of computers to common man, energy saving measures in a domestic environment or other topics related to specific branches of study)
C. PART THREE – COMMUNICATION SKILLS
Written Communication
Preparation of a. Reports
Formal reports Progress reports Feasibility Reports Laboratory reports.
b. Technical Proposals. c. Email. d. User manuals e. Job Hunting material
Resumes Letters for job hunting
f. Business letters g. Memo, Notices, Agenda and minutes
Oral Communication
Oral communication activities like, a. Dyadic communication (Interaction between two persons, example Telephone
conversation) b. Meetings. c. Job interview. d. Group Discussions. e. Debates. f. Case studies.
EEVVAALLUUAATTIIOONN There is no separate evaluation for ISAP skills. But the teachers will consider this for the award of internal assessment marks related to the theory subjects in that semester. The performance of the student will be taken equivalent to an Assignment and an Examination while awarding the internal assessment marks.
