EE2357 PRESENTATION SKILLS AND TECHNICAL SEMINAR
OBJECTIVE
During the seminar session each
student is expected to prepare and present a topic on engineering/ technology,
for a duration of about 8 to 10 minutes. In a session of three periods per
week,
15 students are expected to present
the seminar. A faculty guide is to be allotted and he / she will guide and
monitor the progress of the student and maintain attendance also.
Students are
encouraged to use various teaching aids such as over head projectors, power
point presentation and demonstrative models. This will enable them to gain
confidence in facing the placement interviews
