RATIONALE
Interpersonal communication is a natural and necessary part
of organizational life. Yet, communicating effectively can be challenging
because of our inherent nature to assume, overreact to and misperceive what
actually is happening. Poor communication or lack of communication is often
cited as the cause of conflict and poor teamwork. In today’s teamoriented
workplace, managing communication and developing strategies for creating shared
meaning are crucial to achieve results and create successful organizations. The
goal of the Communicating Skills course
is to produce civic-minded, competent communicators. To that end, students must
demonstrate oral as well as written communication proficiency. These include
organizational and interpersonal communication, public address and performance.
The objectives of this subject are understanding
how communication works, gaining active listening and responding skills, understanding the importance of body
language, acquiring different strategies of reading texts and increasing
confidence by providing opportunities for oral and written expressions

The role of Chemistry and chemical products in every branch
of engineering is expanding greatly. Now a days various products of chemical
industries are playing important role in the field of engineering with
increasing number of such products each successive years. The strength of materials, the chemical
composition of substances, their behaviour when subjected to different
treatment and environment, and the laws of heat and dynamic energy have entered
in almost every activity of modern life. Chemistry is considered as one of the
core subjects for diploma students in
engineering and technology for developing in them scientific temper and
appreciation of chemical properties of materials, which they have to handle in
their professional career. Effort should be made to teach this subject through
demonstration and with the active involvement of students.
