Out-of-class Activity Design -1 Learning Objective(s) of Out-of-Class Activity Students will able to explain the protocol in noiseless channel Key Concept(s) to be covered 1.Simplest protocol 2.Stop and wait protocol
Out-of-class Activity Design-1 Learning Objective(s) of Out-of-Class Activity At the end of watching the videos you should be able to Students able to explain the protocol that was supported for noiseless channel Operation of simplest protocol with flow diagram Operation of stop and wait protocol with flow diagram Key Concept(s) to be covered Simplest protocol Stop and wait protocol

Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected Duration (in min) Additional Instructions (if any) protocol that was supported for noiseless channel Q1.what are the categories of noiseless channel. 58 minutes Watch V1 and then answer Q1
Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected Duration (in min) Additional Instructions (if any) Operation of simplest protocol with flow diagram Q1. which protocol have no flow control and error control Q2.which protocol is unidirectional 2.19 minutes Watch V1 then answer Q1 and watch V2 then answer Q2
Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected Duration (in min) Additional Instructions (if any) Operation of stop and wait protocol with flow diagram Q1:what is the name of error detection technique whether the packet can be corrupted or not Q2: what is the flow diagram of stop and wait protocol 7.12 minutes Watch V2 then answer Q1 and Q2 Total activity duration 10 minutes
About In-class Segment students able to do in higher-order thinking (Analyze-Evaluate-Create). students able to get feedback on their work, either from peers or you. It provides summary of Out-of-Class and In-Class activities.
In-class Activity Design -1 Learning Objective(s) of In - Class Activity Categories of protocol Operation of simplest and stop wait protocol with examples Key Concept(s) to be covered 1.Simplest Protocol 2. Stop and wait Protocol
In-class Activity Design -2 Active Learning activity(ies) that you plan to do Problem solving using Think-pair-share activity Explain the strategy by giving details of Teacher plan to ask questions related to frame transmission of stop and wait protocol i)If Frame is lost or delayed what happens during frame transmission ii)How the timer works in stop and wait protocol Students has discusses the problem with peer instruction or with a teacher Justify why the above is an active learning strategy By using Think –pair –share activity student directly engaging the class ,students able to differentiate how frame transmission occurs without error and with error
In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Three questions are framed at the start of the class and provide summary of noiseless channel Q 1:write the program for simplest protocol Q 2:What happens to the frames if acknowledgement delayed Q 3:what are the advantages of stop and wait protocol
In-class Activity Design -2 Peer Instruction Strategy – What Student Does For each question students vote individually. You have to discuss with peers and come to conclusion. Listen to my explanation.
In-class Activity Design -2 TPS Strategy – What Instructor does Writes the program for simplest protocol step by step how frames are transmitted
In-class Activity Design -2 TPS Strategy – What Instructor does Think (3 minutes) Instruction:Identify what happens to the frames if acknowlegement is delayed What are the advantages of stop and wait protocol Think individually and provide solution
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. Discusses with neighbours answer and agree on the class declarations ,find the final solutions
In-class Activity Design -2 TPS Strategy – What Instructor does Share (~5 minutes) Instructor asks a group to share their answer with class and see whether anyone is having different answers. After sharing is done, instructor gives feedback on the correct solution. Solution:Timer times out- frame is lost and new frame is transmitted from sender to receiver,Receiver finds that particular frame is not received properly,same frame is transmitted again from sender to receiver,wait for acknowlegment,If frame acknowledgement was received before timer times out,frame was received successfully from sender to receiver
Advantage:Accuracy, Next frame is transmitted only when the first frame is acknowledged. In the pair phase students to compare the answers. In the share phase again the different answers are found
In-class Activity Design -2 Justify why the above is an active learning strategy In both strategies, students learned the program of simplest protocol in both sender and receiver and how frame transmission between sender and receiver occurs if error happens. They discuss and come out with final solution which helps to improve their Analytical ability.
