This is the standard Computer Science II course using the C# computer language. The emphasis is on designing and programming object-oriented computer solutions to problems, as well as on the data structures used for this purpose. An introduction to the analysis of algorithms is made. Students must register for both a lecture section and a laboratory section.

Lean about each phase in software life cycle.
Understand the concepts of abstract data types.
Understand the concepts of recursion, inheritance, and polymorphism.

During the term there will be two in-class midterm exams and a final examination. Laboratory assignments will be given in the regularly scheduled laboratory. Pop-quizzes may be given at anytime in lab or lecture without prior notification. Your grade will be computed from your performance on these components using the following weights:
Midterm Exam 1 15%
Midterm Exam 2 15%
Final Exam 20%
(Tuesday, April 21, 2009, 10:15 am -12:15pm)
Pop-quizzes & lab quizzes 10%
(during lab hours, probably in the last week)
(PMT Make up: TBA)
The following grading scale will be used.
A – 90; BA – 85; B – 80; CB – 75; C – 70; DC – 65; D –60.
If you miss an exam (a Midterm Exam or the Final Exam), the decision as to whether or not it is made up and how it is made up will be made on an individual basis. To be excused there must be significant circumstances beyond the student’s control. Generally this will require documentation, such as a doctor’s note in the case of an illness. Normally, if your absence from an exam is excused, you will have to take a make up exam. Contact the instructor asking for a make up exam as soon as it is possible (if possible inform the instructor even before the exam that you will miss).
Students taking this course are required to register for a lab section. Lab grades are based on student performance on programming assignments and quizzes. Additionally, the Programming Skills Mastery Test (PMT) is given in lab.
Lab assignments will be given on a regularly scheduled basis. Many of these assignments will need to be worked on outside of the regular scheduled labs.
Each assignment will have a due date/time. For each day an assignment is late, 5% of the total possible points for the assignment will be deducted. (If an assignment is more than 20 days late, it is no longer worth any points.) Weekends and holidays are all counted when calculating lateness. No assignments may be submitted after 11:59 PM on the day preceding the last day of the classes (before the Final Exam Week). By this time all work should be complete and submitted.
There will be regular quizzes given in the lab. Additionally, pop-quizzes may be given at anytime in the labs or lectures without prior notification. If you miss a quiz for any reason, you will receive a 0 on it.
During the last lab session of the semester, students will be given the Programming Skills Mastery Test (PMT). The test will consist of a short programming problem. Students must program the solution in an essentially complete and correct form in the allotted time. This problem must be solved within the allotted time to earn a passing grade in the course. Students that fail the PMT on their first attempt will be given the second, and last, chance with a different problem.
Producing competent programmers is a primary goal of this course, and therefore a minimum performance in lab is required for students to pass the course.
You must pass the lab with at least 60% of the total possible lab points in order to pass the course regardless of exam scores.
You should strive to complete all assignments. In order to pass the laboratory, you may have at most two assignments incomplete. Even if an assignment is so late that the credit would be 0, it can still satisfy the completeness policy if it is completed and submitted.
You must pass the PMT to pass the course.
You are expected to stay alert and pay attention to the directions/announcements in the class. Cellphones, PDAs, and other electronic devices should NOT be used during the lecture and should be turned-off. If available, please do bring your laptop to the class. Email checking or web-surfing of non-course related material is NOT permitted during the class. You may surf the web only when specifically told to do so. In order to maintain the integrity of the classroom and if I feel it is distracting you or others, I may ask you to turn-off your laptop.
Please note that the incomplete grade - I - is intended for the student who has missed a relatively small portion of work due to circumstances beyond his/her control. In general, performance on work done must be at a level of C or better in order to qualify for an incomplete. An I grade will not be given to replace an otherwise low or failing grade in the class.
The following statement has been approved and distributed by the Western Michigan University Faculty Senate:
You are responsible for making yourself aware of and understanding the policies and procedures in the Undergraduate and Graduate Catalogs that pertain to Academic Honesty. These policies include cheating, fabrication, falsification and forgery, multiple submission, plagiarism, complicity and computer misuse. [The policies can be found at http://catalog.wmich.edu under Academic Policies, Student Rights and Responsibilities.] If there is reason to believe you have been involved in academic dishonesty, you will be referred to the Office of Student Conduct. You will be given the opportunity to review the charge(s). If you believe you are not responsible, you will have the opportunity for a hearing. You should consult with me if you are uncertain about an issue of academic honesty prior to the submission of an assignment or test.
We also encourage you to browse http://osc.wmich.edu and www.wmich.edu/registrar to access the Code of Honor and general academic policies on such issues as diversity, religious observance, student disabilities, etc.
Unless otherwise told, you may not bring aids to exams. Submission of another person’s work in part or whole is not permitted. Learning can certainly occur with discussion of class material and assignments with other students, and we will be doing considerable collaborative activity, but at all times take care that you don’t represent the work of another as your own.
If you are copying another’s work in part or whole, either by hand or electronically, you are going too far.
If two or more people are working so closely together that the outcomes, particularly on significant portions of computer programs, are essentially line-by-line the same in logical structure, they are going too far.
You should not give your completed work to someone else or accept another’s completed work to “review or look at” in either hardcopy or electronic form. This too easily facilitates copying.
Easy availability of information, material, source codes, lecture notes etc on the Internet may make it possible to find solutions to your assignments on the Internet or elsewhere. It is okay to refer to those, understand them and use them to enhance your solutions, generate your own ideas etc. However, you must give proper and full credit to original authors of the work, if you include their ideas and/or solutions. Failing to do so is part of academic and professional dishonesty. It will not be tolerated in this class. Do not give in to temptations.
If you are found responsible for violation of academic honesty in the course, you will receive a course penalty up to and including an E grade for the class. (Note that the Office of Student Conduct can impose additional penalties.)
