For each question they will first vote individually.
Then they will discuss with peers and come to consensus.
Listen to instructors explanation.
EXAMPLE

28. In-class Activity Design -2
TPS Strategy – What Instructor does
First provide a premise
In a standard regulator circuit that uses Zener diode 10 V, the input voltage varies from 25 to 40 V, load current varies from 10 to 20 mA, and the minimum Zener current is 5 mA, the value of the series resistance in ohms will be:

29. In-class Activity Design -2
TPS Strategy – What Instructor does
Think (~2 minutes)
Think individually and identify relationship expression for the zenor diode
EXAMPLE

30. In-class Activity Design -2
TPS Strategy – What Instructor does
Pair (~5 minutes)
Instruction: Now pair up and compare your answers. Agree on one final answer.
While students are pairing and discussing, instructor goes to 2~3 sections to see
what they are doing.
EXAMPLE

31. In-class Activity Design -2
TPS Strategy – What Instructor does
Share (~8 minutes)
Instructor asks a group to share their answer with class and see whether there are different answers. After sharing is done, instructor gives feedback on the correct solution
In the pair phase we ask students to compare the answers.
In the share phase again the different answers are sought.

32. In-class Activity Design -2
Justify why the above is an active learning strategy
In both the above strategies, students are required to go beyond mere listening and execution of prescribed steps. They are required to think deeply about the content they were familiarized in out-of-class and do higher order thinking.
There is also feedback provided (either through peer discussion or instructor summary)
