10. In-class Activity Design -1
Learning Objective(s) of In-Class Activity
At the end of the class, students will be able to,
Design a relation which is in BCNF, 4NF.(CREATE Level)
Analyze whether the given relation satisfies the 4NF. (ANALYZE Level)
Key Concept(s) to be covered
Multi Valued Dependency
Functional Dependency

11. In-class Activity Design -2
Active Learning activity(ies) that you plan to do
Real world problem solving using.
Think-Pair-Share
Concept clarification using.
Peer Instruction

12. 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: Consider the following relation and identify the functional dependency which is suitable for BCNF
A. {sid}{teacher_id,grade}
B. {teacher_id}{course_title} C. {teacher_id} {grade} D. {grade} -->{sid}

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 -2
TPS Strategy – What Instructor does
First provide a premise
Consider a relation scheme given below and convert relation to 4NF.

15. In-class Activity Design -2
TPS Strategy – What Instructor does
Think (~2 minutes)
Instruction: Think individually and identify the order of applying the clauses which provide an efficient solution.

16. 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.
Apply the solution that the students have written by considering following relation and rules of BCNF and 4NF

17. 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 and how the order of applying the operations effect the number of operations performed on the relation.

18. 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)
