Usually our student is so diverse, often times 50% of our student has experience and 50% is a novice learners. I often talk to the student that have experience to the subject on the sides, prior from discussing it to the rest of the student. This way I can set up the discussion in more interesting face, by using the student talk about their experienced on the focal subject, the negative and positives are discuss in more dramatic ways, by allowing them to hear it based on a real experience. Then we can add all the positives points to remember as well the negatives that we can avoid in a long run. This way the experience student learn it twice and retained the information even further better that before. After giving key point to remember, negative and positives.
