Active learning assignments:

A small group of 2-4 students study any one latest and current topic of research from
Biomedical Engineering Journals focusing on any one research paper. They should
understand and analyze the latest trends in the area of the selected topic and prepare and
present power-point slides, which may include videos, animations, pictures, and graphics
for better understanding of the topic. The faculty will guide and help the students in
identifying the topic of research
