Course organization:  The course will be conducted in lecture, small group discussion, demonstration. Knowledge based information will be handled in lecture method. Summary at the end of the class and recap before the next class begins will be diligently followed. Reading assignments will be provided on regular basis. A healthy classroom discussion with interactive sessions will be encouraged. Clarifications can be asked at any point during the class or later. Students are expected to prepare notes for themselves through class lectures and suggested reading materials. Reference details will be shared before and after every class.

 

Class requirements/ expectation from student

Class participation: Students are expected to actively participate in classroom discussions and activities. Students will be rated based on this skill. Incase a student misses a class, the student is expected to obtain missed notes and updates, preferably prior to the next class of the course.

Internal assessments and University examinations will follow the course curriculum which will be covered through classroom teaching, assignments, discussions and models/displays. Assignments will focus on application of class teaching or suggested reading material. Students are expected to adhere to the expected date and time of submission of assignments. 

Formative assessments will be evaluated for 50 marks and will be conducted as per academic calendar

Theory (25 marks)

·         First Internal Assessments (IA) in written format for a duration of 1 hour 30 minutes - 50 marks

·         Second IA will be conducted in the form of online Quiz for 50 marks

·         Third IA in written format + class participation - 50 marks

 

Average of the above three divided by two will be considered for Theory’s final IA marks (maximum 25 marks). Feedback will be provided for these formative assessments on regular basis.
