Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective 1 Assessment Strategy Expected duration (in min) Additional Instructions (if any) Based on Video 1, Summing of Voltage using Op-Amp What will be the output of Op-Amp adder if the two inputs are 2Vpp and 3 Vpp? 2 min Please go through to V1 and V2 on first Video, 5 Marks for Correct answer and submission before 10th Oct,2017, -1 for each day delay Learning Objective 2 Assessment Strategy Expected duration (in min) Additional Instructions (if any) Based on Video 2, Integrator and Differentiator What will be the output of Op-Amp differentiator if the inputs is square wave? Draw waveform. 5 min Please go through to V5 on first Video, 5 Marks for Correct answer and submission before 10th Oct,2017, -1 for each day delay FCA, FDP201x, Mewar University

In-class Activity Design -1 Learning Objective(s) of In - Class Activity At the end of the class, students will Know the real life implementation of Op-Amp mathematical operations. Able to modify the circuit as per the requirements of the practical scenario Key Concept(s) to be covered Use of Op-amp in Real World Problem Solving Use combination of the Op-amp operation for complex functions FCA, FDP201x, Mewar University

In-class Activity Design -2 Active Learning activity(ies) that I plan to do Peer Instruction Think-Pair-Share FCA, FDP201x, Mewar University

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Pose the two PI questions at the start of the class and provide brief overview of Op-Amp Applications. Q 1: What will happen to the output if value of Capacitor is increase to twice the current value? Output will be same Output will be doubled Output will be halfed FCA, FDP201x, Mewar University

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does  Q 2: What will happen if the value of resistances used in Op-Amp Subtraction circuit are halved to the previous value? Output will be same Output will be doubled Output will be halfed FCA, FDP201x, Mewar University

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does  Q 3: What will happen if the integrator is cascaded with the differentiator? Input will be differentiated Input will be integrated Input and output will be same FCA, FDP201x, Mewar University

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 some common agreement. Complete class discussion to get common answer Listen to facilitator’s explanation. FCA, FDP201x, Mewar University

In-class Activity Design -2 TPS Strategy – What Instructor does First take them to the lab where Op-Amp kits and various passive components are available. Students are required to design a circuit to perform a mathematical operation of Z(t)= d/dt{w(t) + x(t) - y(t)} FCA, FDP201x, Mewar University

In-class Activity Design -2 TPS Strategy – What Instructor does Think (~3 minutes) Instruction: Use BODMAS for solving the expression. Think individually and identify which operation will be implemented first and then the sequence of these operations. FCA, FDP201x, Mewar University

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 circuit. While students are pairing and discussing, instructor goes to 2~3 sections to see what they are doing. FCA, FDP201x, Mewar University

In-class Activity Design -2 TPS Strategy – What Instructor does Share (~10 minutes) Instructor asks a group to share their circuit with class and see whether there are different circuits. After sharing is done, instructor gives feedback on the correct solution and how BODMAS and op-amp operation can be used for solving the expression. FCA, FDP201x, Mewar University

In-class Activity Design -2 Justify why the above is an active learning strategy In both the above strategies, students have to be in active mode for thinking and discussing the solution with the peers and finally to instructor. They have to finally implement the circuit and observe the waveforms also. FCA, FDP201x, Mewar University
