One important aspect of a theory presentation is how we end the class. At the end of every class, lecture, demonstration or presentation, we need to review what we just covered. Typically, we do this with a simple Q&A. There is absolutely nothing wrong with using Q&A, as long as it is used periodically and every time we teach.
There are so many ways you can review the material and engage your students in the process.
Here is one idea.
Have each student write down their first name. Then give the students a few minutes to review the material and come up with one word from the topic that corresponds to each letter in their name.
For example. If we are covering Infection Control, here is what I would come up with my name Lisha.
L – Local Infection
I – Inflammation
S – Streptococci
H – HIV
A – Acquired Immunity
Next, have the student study their terms, get comfortable with the definition. Then have each student get up and share their words with the rest of the class, along with the definition. If your class is large, you might consider putting them in small groups of 5 to 7 people.
It is really the same as a Q&A, but the student is actively involved rather than just listening.
