Pedagogy (General Instructions):

These are sample Strategies, which teacher can use to accelerate the attainment of the various course outcomes.

  1. Lecturer method (L) does not mean only traditional lecture method, but different type of teaching methods may be adopted to develop the outcomes.
  2. Show Video/animation films to explain methods of synthesis of nanomaterials.
  3. Encourage collaborative (Group Learning) Learning in the class
  4. Ask at least three HOTS (Higher order Thinking) questions in the class, which promotes critical thinking
  5. Adopt Problem Based Learning (PBL), which fosters students’ Analytical skills, develop thinking skills such as the ability to evaluate, generalize, and analyse information rather than simply recall it.
  6. Topics will be introduced in a multiple representation.
  7. Show the different ways to solve the same problem and encourage the students to come up with their own creative ways to solve them.
  8. Discuss how every concept can be applied to the real world – and when that’s possible, it helps improve the students’ understanding.
