Course Information
•
It is a coordinated course.
– Every section will have its own quizzes, but grading policy, topic breakdown,
and synchronized level of questions in the quizzes will be coordinated.
– Midterm and Final Exams will be common and physical for all sections.
– There are Practical and programming assignments with a weight of 10% of the
course grade. In the assignments, you will practice selective exercises and
practical programming assignments on the OS topics, some may not be
covered in the lecture for breadth coverage.
– Assignments will be managed by the Lab Instructor.
• Pre-requisite Course:
– COE 233/301 (Computer Organization/Digital Logic/Assembly Programming)
• Pre-requisites by Topics:
– Linux and C programming language awareness are required for the Lab.
– Fundamentals of a data structure for developing lab assignments,
– Algorithms and problem-solving,
– Computer Organization and Assembly Programming.
– Linux Mint and C programming toolkit are installed on the machines of the OS
Lab (Building 22-Room 336).

9th edition still can be used, but notice the chapter numbering.
 Topics presented in the classes should be your main reference.
 We may elaborate more on some topics than what
is there in the textbook.
 We may cover concepts that do not exist in the textbook.
 We will cover some exercises that are not in the textbook.
 Textbook exercises are very important for quizzes and exams.

•
•
•
•
•
•
Attendance will be taken at the end of the class.
You need to have your mobile phone to automatically check for
your attendance through the Darajati application.
You need to attend in your section time to be able to check
for your attendance.
Attending other sections is not allowed for that reason.
That will start next Sunday after finishing the period of
add/drop classes.
You will have about four absences FREE of charge.
Up to the ninth absence, each subsequent absence is worth 0.5 percentage points of your overall score.
After ten absences without any excuses, you will
automatically be assigned a DN grade (according to university
regulations).
An unexcused absence will become an excused one ONLY
by an official letter from the student’s affairs office.

Collaborative Environment
• We would like the course to run smoothly and to be enjoyable for you.
– Help each other to understand the OS fundamentals.
– Be supportive and collaborative with me and with your colleagues.
– Feel free to ask about any ambiguous concepts during the class.
• Feedback, by email or in person, is always welcome.
– Feel free to let me know what you find just good or bad about the
course.
• I am really on your side and doing my best to help you.
– Do not miss-interpret the democratic way of interaction.
– I can handle criticism or difference of opinion friendly.
– Your honest course-related feedback will be highly appreciated
and implemented.

Learning Strategies
•
Passive Learning/Instructor-Centered: The students are passive and just receive
information and ideas from the instructor.
•
Active/Cooperative Learning/Student-Centered: The students should be involved in
doing, observing, self-learning, presenting, and giving feedback through:
– Reading the materials before coming to the class.
– Engage in the class and discuss the presented topics.
• You will be assigned a book chapter/s to read, and understand.
• You will be asked to summarize what we said at the end/beginning of the class.
• You may be asked to answer some questions during the classes.
•
As a motivation, a part of the course assessment will be assigned for such activity.
•
Moreover, you will be rewarded pounce marks by actively participating and engaging in
the classes through asking or answering questions, this is a chance to make up the
quizzes and exams.
•
Your feedback about some issues will be highly appreciated: i.e.
• What kind of questions and topics should be covered in the exams in a way
that we keep the standard quality of learning outcomes?
• Time of the exams and quizzes.
