What is Intro to Computer Science II?
Obviously, it is a continuation of CS I. But what does that mean? I would like to use the analogy to college composition I & II. In composition I, you learn how to put words together, grammatically correct, into sentences. You then learn how to put sentences together to form paragraphs. In composition II, you take those skills and learn how to create entire documents to express ideas. For computer science, this means finding algorithmic solutions that scale well. What is an algorithm? It is a sequence of steps to solve a problem. In a fundamental way, computer science is problem-solving. For many problems, there is not a single answer. In this course, you'll find that within broad guidelines (i.e. the requirements), much is left up to you to specify.
In CS I, you learn the symbols and syntax to create grammatically correct programs, i.e. they compile and run. You learn how to adjust the flow of control (loops and decisions) to get the programs to perform the intended work. In computer science II, you learn how to create novel solutions to problems presented to you. The assignments are more open-ended than what you had in CS I. In that course, it is important that you have structures and limits so we can ensure you are using the skills correctly. In this course, you are given requirements where it is up to you to provide the design and structure to satisfy those requirements. If you have doubts about what is required, ask!
A Big Jump
This is a big jump in 10 weeks! It is critical that you learn how to read and understand requirements. It is important that you understand how to resolve apparent gaps in the requirements to fill them in. We do not tell you how to create programs (other than requiring specific items). That also means we are not looking for "A" correct answer. If you use the required tools and the program does what is asked, then you did it (mostly) right! Enjoy your freedom!
What do I mean by freedom? The freedom comes from project and lab requirements that are intentionally non-specific. We present problems with some of the parameters required. Others are left for you. You will include design documents for the assignments so you can outline how you resolved these gaps. You can focus on the design, and not just try to implement specific tasks provided by us. In 161, you were learning new skills and needed that structure. In 162, we try to give you a chance to think it through by yourself. We encourage you to work in groups (an important professional skill). Although all the labs and projects are individual work (except the group project), you can use the Piazza forums and your own study group for the projects and labs.
Freedom is also from student-driven learning (SDL). We encourage a similar process for you to learn new skills. You have an idea of what you need to know. We try to guess and provide study materials that we think you'll need. But what if we're wrong? SDL encourages the student to reflect on what they know. Once you determine what else you need, you can go get it. Maybe it's in a lecture. Maybe it's in the textbook. Maybe you find a video online that works. The tricky part is that what works for one may not work for another. We're here to help you find or to provide that information. This is the motivation for putting together synchronous sessions so you can work with classmates and a TA face to face (or as close as we can get in an online environment).
As with much freedom, there are responsibilities. In this case, much of the work are problems for you to solve. You must also solve the "problem" of what additional knowledge you require.
What to do?
Please be aware that some links in this tab are only accessible to registered students. Please go over all the contents in the Course Syllabus page. Please read the course policy and schedule carefully. Mark the important dates like due dates of assignments and tests on your own calendar. Finish the course policy quiz and get full points to unlock week one module. There are some useful links under the resources module. Please check them out as well. You might need them for the first few assignments. Also check out the code related policy under the "Code related things" module.
Please register the course Piazza forum. There are two general discussions during the first week on Piazza. One is simply a chance for you to find classmates close to you. You should introduce yourself on CS162 Piazza forum by making a short post. We encourage you to form study groups through this discussion. The study group can be an online group or a local group where you can meet in person. The other is to start the topic discussions on Piazza. I will post more discussion topics as we introduce new contents. For more details, please check this page: A Note About Group Activities.
Please check the university academic calendar for start date, deadlines, holidays and so on. Also, be sure to check the "Resources" module and "Ecampus and other policies" module, where you can find information about Disabilities Access Services, The Valley Library, the OSU Computer Helpdesk, and more.

Please post all the course-related questions on Piazza discussion forum so that the whole class may benefit from our conversation.
Please email us for matters of a personal nature. We have two instructors in one section this term. You can contact any of us. To keep the communication more consistent, for student's last name from A to L, you can contact Luyao Zhang for the course related questions, and for student's last name from M to Z, you can contact Samarendra Hedaoo. Please include the tag [CS162 Fall 2019] in your email subject and use your OSU email instead of the Canvas email. We will reply to course-related questions and emails within 48 hours.
We will also send out the course updates through Canvas Announcement to the whole class and you will receive an email notification on each announcement. It is your responsibility to check your OSU email and the Canvas course website regularly to keep updated.
For questions and requests about grading and re-grading, please post privately on Piazza and @ your grading TA. Please don't post any grade-related request on Slack. TAs will hold office hours online (Zoom or Slack) from week 1 to week 10. The office hour schedule and link will be posted on Canvas in the "Start here" module. TA's contact information and who will grade your assignment will also be posted in the "Start here" module. These contact information will be updated within week 1.
Measurable Student Learning Outcomes
At the completion of the course, students will be able to:
- Design and implement programs that require:
(a) multiple classes, structures
(b) hierarchies of classes that use inheritance and polymorphism
(c) understanding of abstraction, modularity, separation of concerns, exception handling
- Construct and use basic linear structures (arrays, stacks, queues, and various linked lists) in programs, and be able to describe instances appropriate for their use.
- Classify moderately complicated algorithms in these complexity classes: O(1), O(log n), O(n), O(n log n), and O(n2).
- Develop test-data sets and testing plans for programming projects
- Produce recursive algorithms, and choose appropriately between iterative and recursive algorithms.
Graded Course Works
- Tests and Quizzes
There will be a policies quiz at the beginning of the course, one course survey at the end of the term, and four open-book tests. Each test will have around 20 questions (T/F and multiple choices) on Canvas. You may take the test a second time, but only the score of the final attempt will count. Each attempt will be timed. You may not get the same questions each time.
There are 4 larger programming project assignments. An assignment generally includes understanding the requirements, designing the program, implementing and testing the code, and writing a reflection document. Programs are graded on how well they solve the assigned problem, meet specifications, use proper formatting and documentation. All the 4 projects will be individual work.
Labs are small development projects that reinforce the topics presented each week. You will have one lab each week, and ten labs in total. All the labs will be individual work.
- Group Activities
Activities include two types of activities that support the course objectives. You will discuss certain topics on some concepts and techniques on Piazza with your classmates. There is a final reflection discussion (week 9 & 10) about your journey through 161-162 to learn how to program. This discussion will be on Canvas and will be available for about 2 weeks period. There will be two project peer reviews and you need review other student's code and give comments.
- Final Project
There will be a final project instead of a final exam. It will be similar in the format to the projects but will cover concepts from the entire course. The final project is also individual work. It will serve as the "Portfolio" in this course which means you can post the entirety of the assignment publicly (e.g. Github, personal website, etc…) after the course is ended.
The list below indicates how the course learning outcomes will be measured:
- Projects – 30%
- Labs – 30%
- Group activities – 10%
- Quizzes/Test – 15%
- Final project – 15%
- Total – 100%
|Grade letter||Percentage floor|
REMINDER: A passing grade for classes in CS is a C or above. A C- in a CS course is not considered a passing grade toward a CS degree or as a prerequisite for future CS classes.
Your grade for each assignment will be posted on Canvas (generally after one week of the due date). Canvas is used to simply record the scores. The final score displayed is only approximate. At any time, if you want a better estimate of your current grade in the course, please email the instructor from your OSU email account.
Re-grading: If you have a question about an assignment grade, you must contact your TA by post privately on Piazza within ONE WEEK of receiving your grade. You can use words like "regrading request lab 1 @ TA's name" in the post subject so we can see it right away. After one week, you will not be able to dispute your grade.
- The final project, last lab, group activities and test MUST be completed by the deadline, and no late submission would be accepted for grading purpose.
- Projects and labs should be completed by the due date. If you do not submit the assignment by the due date, there is late penalty:
- Late <= 1 day: 10% penalty;
- 1 day < Late <= 3 days: 20% penalty;
- 3 days < Late <= 7 days: 30% penalty;
- Late > 7 days: not be accepted.
Work submitted after 7 days will not be accepted. It is your responsibility to manage your time. If there are extenuating circumstances, please contact the instructor as soon as possible before the deadline.
- You have three bonus days in the entire term to apply to any labs/project. You can use it all at once for one assignment (if you are late for 3 days), or split it and use one day each for three assignments (no "half" day).
- How to apply the bonus day: leave a comment on Canvas under that assignment submission, saying that you would like to apply x bonus days for this late submission, and you have y bonus days left after that. When TAs are applying late penalty, they will look at your submission time and your comments. If you don't leave a comment there, TAs will directly apply the late penalty.
- If you have a really tough situation that might affect your progress a lot (illness, job duties, family emergency...), you should contact me immediately and ask for extensions other than the 3 Bonus days. Don't wait until the due date or even past the due date to explain your personal situations and ask for extensions. If you are not sure whether to ask for it, better do it.
Course Work Submission
- All work must be submitted before 23:59 (Pacific Time Zone) on the date they are due.
- All the files need be archived in a zip file
- Your submission must be named in the following format: assignment name + your last name + your first name for individual assignment (eg: Lab1_Jones_Adam).
- All the projects and labs must be submitted on Canvas.
- Programs must compile and run on the EECS server (flip) or they will not be graded. Programs must include a makefile.
- If you are not sure you submit the correct file, download it and check it. Make sure you include everything in your submission!

Programming assignments in this course are considered Take Home Programming Tests. You must do your own work, entirely.
To Do & Not To Do:
You MAY discuss the meaning of assignments, general approaches, and strategies with other students in the course.
You MAY show your code to the TAs or instructor for feedback and help.
You MAY NOT ask another student for help debugging your assignment code.
You MAY NOT use or copy code from any other source, including the internet. You MUST write your own code for your assignments. That doesn't mean we don't allow you to search solutions online when you meet problems. That means, if you learn how to implement some function from online recourse, do not just copy/paste the code. Make sure you cite the resources properly if the code is exactly the same, and also make sure you could write the code by yourself now without looking at the original source.
We use plagiarism-detection software to check your code against the code from other students. It is quite sophisticated and can easily see through variable name changes and formatting differences. If you are found in violation of any of the above policies, whether you are the giver or receiver of help, you will receive a zero on the assignment or fail the course (Instructor's decision). For further information, visit Academic or Scholarly Dishonesty, or contact the office of Student Conduct and Community Standards (SCCS) at 541-737-3656.
Statement Regarding Students with Disabilities
Accommodations are collaborative efforts between students, faculty and Disability Access Services (DAS), with accommodations approved through DAS are responsible for contacting the faculty member in charge of the course prior to or during the first week of the term to discuss accommodations. Students who believe they are eligible for accommodations but who have not yet obtained approval through DAS should contact DAS immediately at 541-737-4098.
NOTE for Disability Access Services (DAS) – If you have accommodations through DAS for extra time on your exams or quizzes it is very important that you communicate with your instructors as soon as possible. Ask the instructor to double check all timed exams and quizzes to make sure that extra time has been given to you for each exam. The instructor has to do this for each timed exam or quiz manually
If you start an exam and do not see your extended time, please have your proctor call Ecampus Testing or try to contact your instructor for assistance. We can give you extra time while you are still taking the exam if we can be contacted before the exam submits.
After you read all the details in the syllabus and start here module, please take the syllabus quiz and get full points to unlock the week 1 module.
