NOTE:- THE PROJECT MAY IDENTIFIED AT THE BEGINNING OF 4TH SEMESTER
RATIONALE
Realising the great importance of student exposure to world of work for his
professional growth, two spells of industry oriented projects-minor and major have
been included in the curriculum. It is necessary that teachers to play a pro-active
role in planning and guidance of individual students for optimizing the benefits of
the activity in stipulated time.
Minor project work aims at exposing the students to industrial/field practices so as
to have an appreciation of size, scale and type of operations; and work culture in
the industries. Also the their application in solving field/industrial problems. The
work done in minor project work will also prepare them in taking up problem
solving at latter stage under major project work.
Some of the projects are listed below which is just a guideline for selecting the
minor project. Students can also select any project with the advice of his teacher.
1.
Regulated power supply.
2.
Timers using 555 and other oscillators.
3.
Touch plate switches- transistorized or 555 based.
4.

If the project is linked to industry/field, the students may be asked to:
a)
Study various types of materials being used.
b)
Learn and Study various operations /processes.
c)
Know about various measuring instruments and test equipment being used.
d)
Study the plant layout and material handling in an industry.
e)
Have knowledge about production planning and control in an industry.
f)
Know about various quality control techniques and safety measures
adopted.
h)
Prepare list of specifications of equipment and machines used.
(This list is only suggestive, however other problems may also be identified
depending on local industries)
For effective planning and implementation of the above, it is suggested that
polytechnics/institutes should:
a)
Identify adequate number of industrial/field organizations and seek their
approval for deputing students for exposure/visits.
b)
Prepare a workbook (which can be used by students) for guiding students to
perform definite task during the above-mentioned exposure.
c)
Identify teachers who would supervise the student’s activities and provide
guidance on continuous basis during the project work.

Important Notes:
1.
The criteria for evaluation of the students have been worked out for 100
maximum marks. The internal and external examiners will evaluate
students separately and give marks as per the study and evaluation
scheme of examination.
2.
The teachers are free to evolve another criteria of assessment, depending
upon the type project work.
It is proposed that the institute may organize and annual exhibition of the project
work done by the students and invite leading industrial organization(s) in such an
exhibition. It is also proposed that two students or two projects, which are rated
best, be given merit certificate at the time of annual day of the institute. It would
be better if specific industries were approached for instituting such awards.
