10. In-class Activity Design -1
Learning Objective(s) of In - Class Activity
At the end of the class, students will be able to,
Understand the use of injection moulding machine for manufacturing of plastic components.
Key Concept(s) to be covered
Practical applications of Injection Moulding Process
Constructional details of Injection Moulding Machine

11. In-class Activity Design -2
Active Learning activity(ies) that you plan to do
Think Pair share
Explain the strategy by giving details of
First 30 minutes teacher will explain the constructional details of injection Moulding Machine & discuss practical applications.
Students will think, discuss with peers & share the answers with each other.
Justify why the above is an active learning strategy
This activity enables student to think individually & discuss with peers which results in engagement of student in reading, thinking & explaining.

12. In-class Activity Design -2
TPS Strategy – What Instructor does
Think (~2 minutes)
 Q 1: Which types of components can be manufactured by using Injection Moulding Process.
Q 2: What is the function of ejector pins in injection moulding machine.
Think individually and identify the real life end products of injection moulding machine.

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

14. 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.

15. 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)
