About Out-of-Class Segment

Concept and Definition of Operating System:

An operating system (OS) is responsible for the coordination and management of the activities and sharing of resources in the computer system.

The operating system works as a host of application programs that run on machine.

Process State Diagram:

In a computer system, the processes occupies variety of states. These different states recognized by the operating system. These states are a useful abstraction to understand the processes.


About Out-of-Class Segment

CPU Scheduling:

CPU scheduling allows one process to use CPU while the execution of another process is on waiting state due to unavailability of any resource, hence making full use of CPU. The main goal of CPU scheduling is to make the system efficient and fast.

Types of CPU Scheduling: List of scheduling algorithms are as follows:

First-come, first-served scheduling (FCFS) algorithm.

Shortest Job First Scheduling (SJF) algorithm.

Shortest Remaining time (SRT) algorithm.

Non-preemptive priority Scheduling algorithm.

Preemptive priority Scheduling algorithm.

Round-Robin Scheduling algorithm.

In-class Segment

This section helps you design the in-class segment of Flipped Classroom Strategy.


About In-Class Segment

Make sure that In-Class segment contain activities for effective learning

• In active learning student goes beyond listening, copying of notes.

• Execution of prescribed procedures.

• Students are required to talk, write, reflect and express their thinking.

Engage students in higher-order thinking (Analyze-Evaluate-Create).

Ensure that students get feedback on their work, either from peers or you.

Ensure to provide summary that connects Out-of-Class and In-Class activities.


In-class Activity Design -1

1. Solve real-life scenario problems involving CPU Scheduling and concept of Operating system

2. Analyse criteria for scheduling

Learning Objective(s) of In - Class Activity

1. Use of Operating System

2. Use of CPU Scheduling

Active Learning activity(ies) that you plan to do

1. Active Learning Strategy

Explain the strategy by giving details of

1. What Teacher will do?2. What Student will do?

Justify why the above is an active learning strategy

Active Learning activity(ies) that you plan to do

Real world problem solving using.

Think-Pair-Share

Concept clarification using.

Peer Instruction



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 three CPU-intensive processes, which require 10, 20 and 30 time units and arrive at times 0, 2 and 6, respectively. How many context switches are needed if the operating system implements a shortest remaining time first scheduling algorithm? Do not count the context switches at time zero and at the end.

A. 1

B. 2

C. 3

D. 4



Peer Instruction Strategy – What Teacher Does

Q 2: Which of the following process scheduling algorithm may lead to starvation

1. FIFO

2. Round Robin

3. Shortest Job Next

4. None of these



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.



TPS Strategy – What Instructor doesA scheduling algorithm assigns priority proportional to the waiting time of a process. Every process starts with priority zero (the lowest priority). The scheduler re-evaluates the process priorities every T time units and decides the next process to schedule. Which one of the following is TRUE if the processes have no I/O operations and all arrive at time zero?



TPS Strategy – What Instructor does

Think (~2 minutes)

Instruction: Assuming that every process starts with the priority 0

Think individually and identify the scenario




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.




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

In the pair phase we ask students to compare the answers.

In the share phase again the different answers are sought.



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)
