LESSON PLAN: 2017-18
A Good Lesson Plan is instrumental for the delivery of course content in a competent way so that students get benefited in view
of learning, developing good skill set, updating with current trends in industry etc., Delivery including latest trends in the technology
and applications brings deep insight of the course in students. As the plan includes the home assignments, quizzes, course projects
etc., it carries out the continuous assessment of student learning (course outcomes).
The course delivery in adherence to the lesson plan is ensured through course level audit forms on regular basis.
