CURRICULUM

DIPLOMA IN PLASTICS ENGINEERING

Shri Bhagubhai Mafatlal Polytechnic started 3 years Diploma courses and was affiliated to the board of technical Examinations, Maharashtra State,in 1963. Since 1969, academicfreedom was granted to the Polytechnic, which enabled it to evolve curriculum and examination scheme and to introduce inplant training which involved industry institute interaction. Thus 4 years semester sandwich pattern came in existence. Since 1978-79 academic freedom was extended to all the full time diploma courses. In 1989 – 1990 ,full autonomy was granted to all seven full time diploma courses.

As a further development to the above, the multi point entry and credit system (MPECS) was initiated in 1981 on progressive basis.in this scheme students can regulate their pace of studies within the rules prescribed.

From 1993-94, full academic autonomy was extended to all 19 courses, which includes full time diploma, part time diploma, and post diploma courses. The students have to qualify for appearing in the final examination as per details given in MPECS rules. The examination is conducted by the institute and the final diploma is awarded by the institute at the convocation function.

Syllabus for semester I&II, which is common to all full time disciplines, is printed

The scheme of training and academic instructions is schematically shown below:

The students receive institutional training for the first four semesters.In the fifth semesters they are given inplant or field training. They return to the polytechnic in the sixth semester for institutional training. In the concluding eighth semester, they again receive inplant or field training. This scheme enables the students to be exposed to industry during their training provides for practice orientation and improves their prospects for employment.

(3) RATIONALE :

In take level of the students is S.S.C or is Equivalent. These students have studies English for minimum of 6 years. Expected level of heir Active Vocabulary is 2500 words from the Nagpur list of High Frequency words. However, in practice it was found that the students, particularly from the vernacular medium have only 1500 words at their command. They need to have course in English subject to offset this situation. Therefore, the first semester engineering course students need to study English. Further, in this age of information, Communication Skill is essential to everyone. This is equally true in the case of Engineers. Engineers having sound knowledge of the technical subjects should be able to communicate the same to his superiors, peers and subordinates in their routine work environment. Having a sound Communication Skill will enable the engineering students to learn and interprets the subject effectively. This saves time and money and enhances the effectiveness of the engineer’s performance.

18

(4) OBJECTIVES :

(i) The student will increase his English vocabulary to a minimum of 2500 words (Nagpur List) through the prescribed text and grammar exercises by various techniques such as synonyms, Antonyms, One word substitutes, Prefixes & Suffixes and Comprehension of new words, Idioms and Prepositional Phrases. Students will be able to use principles to solve problems in Mathematics at Higher Semester level.

(ii) Students will understand the various uses of grammar items such as Voice in English sentences, Degrees of Comparison, Tenses, Direct and Indirect Speech in formation of various kind of sentences.

(iii) Students will master the important structures of English sentences to enhance their communication skill so that they can interact (orally and in writing) with people at different levels and in different situations with confidence.

(iv) This subject will enable the engineering students to understand the following:

Effective Oral Communication

Better Written Communication

How to Improve Human Relations

How to Overcome Barriers to Communication

The need for Enhancing Personality

2. RATIONALE

The skills of Project Management have become important in all types of business and at all levels of work hierarchy. The purpose of development of Generic Skills is to develop the necessary skills, which will make students confident and competent in managing and executing engineering projects.

3. OBJECTIVES

Over a period of time it has been observed that effectively of polytechnic students, their utility at work place can be enhanced by imparting generic skills right from entry in the polytechnic. The generic skills are life skills, they are lifelong skills, whose edge needs to be sharpened every moment.

The content is divided into 4 logical units:

1. Information 2. Communication Skills 3. Self Development 4. Task Management

It is designed by keeping self in focus with a clear objective of developing Generic Skills, to enhance the capabilities in the field of searching, assimilating and using information on job. Developing self and managing given tasks, finally to present himself as a technomenger.

It is an effort to develop student that enables him to be successful in finding a practical and reaction solution to any problem he comes across. It covers more or less all aspects of life skills. The development of subject is progressively ascending parallel to development of study in polytechnic.
