9. 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 importance of ECM as a modern manufacturing process.
Analyze the process parameters and MRR of ECM.
Appraise the applications of ECM.
Key Concept(s) to be covered
Faraday’s Law of Electrolysis
Process parameters and MRR of ECM

10. In-class Activity Design -2
Active Learning activity(ies) that you plan to do
Concept clarification using.
Peer Instruction
In-depth understanding using.
Debates

11. In-class Activity Design -2
Peer Instruction Strategy – What Teacher Does
Pose the two PI questions at the start of the class and provide summary of basic identities and expression simplification.
Q 1: What is/are the suitable electrolyte(s) for ECM process?
Kerosene
HNO3
Water
NaCl

12. In-class Activity Design -2
Peer Instruction Strategy – What Teacher Does
 Q 2: Which of the following are the features of ECM process?
a. The electrolyte poses the risk of corrosion to tool workpiece and equipment.
b. Only electrically conductive materials can be machined.
c. High Specific Energy consumption.
d. Both electrically conductive and non-conductive materials can be machined

13. In-class Activity Design -2
Peer Instruction Strategy – What Student Does
For each question they will first vote individually.
Then they will discuss with peers and come to consensus.
Listen to instructors explanation.

14. In-class Activity Design -3
Debate
Students are divided into 4 groups and given topics to defend and debate upon. For example the following topics were given to the teams.
Team 1: Will talk about advantages of ECM process and remaining teams will question and negate/differ the advantages.
Team 2: Will talk about disadvantages of ECM and others will negate/ differ.
Team 3: Will talk about applications and ECM and other teams will question the applicability.
Team 4: Will talk about economics of ECM process and other teams will differ.
In this way, in-depth understanding of the concept of ECM is possible.

15. In-class Activity Design -4
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)
