ACTIVE LEARNING ASSIGNMENTS: Preparation of power-point slides, which include videos,
animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate
chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point
slides should be put up on the web-site of the College/ Institute, along with the names of the students of the
group, the name of the faculty, Department and College on the first slide. The best three works should
submit to GTU.
