In-class Activity Design -1 Learning Objective(s) of In - Class Activity At the end of the class, students will be able to, Compute the power delivered by complex circuits (ANALYZE Level) Apply superposition theorem to simplify a circuit (ANALYZE Level) • • Key Concept(s) to be covered § Applying basic laws to a given circuit (those laws that are discussed in this learning resource) § Limitations of Superposition theorem Department of ECE, Bennett University 12

In-class Activity Design -2 Active Learning activity(ies) that you plan to do Concept clarification using § Peer Instruction Finding the limitations of superposition theorem using. § Think-SOlo-Pair-Share (TOPS) Department of ECE, Bennett University 13

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does At the starting of the class, teacher provides summary of the basic laws used to simplify the electrical circuits. Two PI questions were asked. First PI question as below is asked. Q 1: Using Kirchhoff’s laws, Calculate the power consumed by the resistor R L. What is the value of RL if the power consumed is maximum. are your observations. Department of ECE, Bennett University 14

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Q 2: Apply superposition theorem to calculate the power consumed by the 4 k. W resistor. Department of ECE, Bennett University 15

In-class Activity Design -2 Peer Instruction Strategy – What Student Does § § § For each question they will first answer individually. Then they will discuss with peers and come to consensus. Listen to instructors explanation. Department of ECE, Bennett University 16

In-class Activity Design -2 TOPS Strategy – What Instructor does Teacher asks the following question. Is the power consumed by a load resistor due to individual sources in a circuit adds up to the power consumed by the load resistor due to all sources put together? Department of ECE, Bennett University 17

In-class Activity Design -2 TOPS Strategy – What Instructor does Think (~2 minutes) Instruction: Students were asked to think on the relation between voltage (polarity) across a resistor and current through a resistor (direction of current) and link it to the sign of the power consumed by a resistor. Then apply the thinking to “Is the power consumed by a load resistor due to individual sources in a circuit adds up to the power consumed by the load resistor due to all sources put together? ” Department of ECE, Bennett University 18

In-class Activity Design -2 TOPS Strategy – What Instructor does Solo (~10 minutes) Now teacher re-opens Q 2 with the following question. Calculate the power consumed by the 4 k. W resistor individually due to 8 m. A current source (P 1) and due to 12 V source (P 2). Is this power equal to the total power as calculated in (Q 1)? What are your observations and reasons behind your observations. Department of ECE, Bennett University 19

In-class Activity Design -2 TOPS 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. Department of ECE, Bennett University 20

In-class Activity Design -2 TOPS Strategy – What Instructor does Share (~8 minutes) Instructor asks a group to share their answer with class and see whethere are different answers. After sharing is done, instructor gives feedback on the correct solution on why the power delivered to load resistance by individual power sources doesn’t adds up to the power delivered to the load resistance by keeping all the power sources together. Department of ECE, Bennett University 21

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. • are required to think deeply about the content they were familiarized in out-of-class and do higher order thinking. • are required to work on their own to solve a problem in the class Finally, an immediate feedback is provided either through peer discussion or instructor summary Department of ECE, Bennett University 22
