CMSC 330, Fall 2006
Organization of Programming Languages
Prerequisites and Description
A study of programming languages, including their syntax, semantics, and implementation. Several different models of languages are discussed, including procedural (e.g., C, Pascal), functional (e.g., ML, LISP, Scheme), rule-based (e.g., Prolog), and object-oriented (e.g., Java, C++, Smalltalk). Language features such as formal syntax, scoping and binding of variables, higher-order programming, typing and type polymorphism, and object inheritance are explored.
List of Topics (Tentative)The following list of lecture topics will vary according to the pace of lecture.
Programming projects will be developed on the OIT Grace UNIX Cluster, grace.umd.edu. You will use your own Glue account to access the cluster and do coursework, so if you do not have a Glue account, request one immediately online.
If you have access to another system you are welcome to do your development there instead, but all project submissions must work correctly on the Grace cluster, and your projects will be graded solely based on their results on the cluster. Because language and library versions may vary with the installation, in unfortunate circumstances a program might work perfectly on your system but not work at all on the cluster. Thus we strongly recommend that if you develop any project on another system, you should complete it several days early to have time to address any compatibility problems.
Office Hours and Web Forum
Office hours for the instructional staff will be posted on the course web page a few days into the semester.
While we will provide assistance with assignments during office hours, you are responsible for developing and debugging your own programs. Do not rely on the instructional staff to make your project work. Lower-level CMSC courses provide extensive debugging and development help in office hours, but upper-level CMSC courses expect students to complete projects with minimal extra help. Therefore in CMSC 330, we will provide less debugging help than some students may be used to. If you come in with a question, expect to be pointed in the right direction, but it will be up to you to finish solving the problem on your own.
Important announcements will be made in class or in the class web forum. Please make it a habit to check the web page and class web forum daily. You may also use the web forum to ask general questions of interest to the class as a whole, e.g., administrative issues or project clarification questions. Please do not post any information that would violate the university academic integrity policy.
You are responsible for all material discussed in lecture and discussion section and posted on the class web page, including announcements, deadlines, policies, etc. During the semester we may provide ungraded practice homework exercises and solutions. While we will not collect these exercises, completing them is essential preparation for exams. You may work together on these ungraded homeworks, and you may of course come to office hours for additional help.
Your final course grade will be determined according to the following percentages:
We expect to assign 6 programming projects, though there is some chance we will assign more or fewer projects, in which case they will be given equal weight out of 45%.
Any request for reconsideration of any grading on coursework must be submitted within one week of when it is returned. Exam regrading requests must be made in writing. Any coursework submitted for reconsideration may be regraded in its entirety, which could result in a lower score if warranted.
Final course grades will be curved as necessary, based on each student's total numeric score for all coursework at the end of the semester. Important: Completing the programming assignments is an essential part of the course. Therefore, we may fail any student who does not make a good-faith attempt on all course projects, regardless of the student's performance or scores on the other coursework.
Projects must be submitted electronically following the instructions given in class. Projects may not be submitted by any other means (e.g., please do not email your projects to us). It is your responsibility to test your program and verify that it works properly before submitting. All projects are due at 11:59:59pm on the day indicated on the project assignment, according to the submission server's internal clock.
Projects may be submitted up to 24 hours late for a 10% penalty. For example, a project that would earn 90 points for an on-time submission will earn 81 (which is 90 times 0.90) if submitted up to 24 hours late. Projects may be submitted between 24 and 48 hours late for a 25% penalty. Projects may not be submitted more that 48 hours late. Note that your project score as it appears on the project submission server will not include any late penalties. Any penalties will be incorporated into the final project grade on the grade server. If you submit on-time, late, and really late (24-48 hours), your project will received the maximum of the three penalty-adjusted scores.
Project extensions will not be granted due to system problems, network problems, power outages, etc., so do not wait to submit a project until the night it is due. You may submit multiple times up to the deadline, and only your last on-time submission is graded. Similarly, if you submit late, only your last submission before the 24-hour deadline will be graded, and the same for the 48-hour deadline. No consideration in grading will be made for errors made in transferring files or submitting the wrong version of your project. Having a working, unsubmitted version will not count; only submitted code will be be counted.
Unlike lower-level programming classes, we will not provide you with test cases before projects are due. Instead, you will be responsible for developing your own techniques for testing your projects. To reiterate: your projects will be graded based on test cases not provided in advance. Because grading is done automatically, you must follow the project specification exactly. Also, while projects will generally not be graded on style or documentation, we reserve the right to manually grade program source code for some projects.
Finally, any "hard coding" in a project assignment will result in a score of zero for that project, and is considered a bad-faith effort. Hard coding refers to attempting to make a program appear as if it works correctly, when in fact it does not. One example of hard coding would be printing the desired output instead of computing it. This is only one example, and if you have any questions as to what constitutes hard coding, be sure to ask ahead of time.
The class includes two midterms and a final exam. Tentative dates for the exams are posted on the class web site. The exact dates will be confirmed later, and may vary due to the progress of lecture and other factors. We will let you know the exact deadlines well in advance. Midterms will be held in discussion section, though possibly in a different location. The final exam date is determined by the University. The final exam can be rescheduled only for students who have another final at exactly the same time, or for students with three or more final exams scheduled on the same day. If either of these situations applies to you, you must inform the instructor during the schedule adjustment period for any allowances to be made. Please also let us know immediately if you have a conflict with a midterm date.
Besides the policies in this syllabus, the University's policies apply during the semester. Various policies that may be relevant appear in the Undergraduate Catalog.
If you experience difficulty during the semester keeping up with the academic demands of your courses, you may consider contacting the Learning Assistance Service in 2201 Shoemaker Building at (301) 314-7693. Their educational counselors can help with time management issues, reading, note-taking, and exam preparation skills.
Missing an exam for reasons such as illness, religious observance, participation in required university activities, or family or personal emergency (such as a serious automobile accident or close relative's funeral) will be an excused absence. However, excused absences must be requested in writing and must include documentation that the absence qualifies as excused.
For example, for medical absences, you must furnish documentation from the health care professional who treated you. The documentation should include the name and phone number of the health care professional and should explicitly state the dates and times that you were incapacitated and therefore unable to attend. The dates and times must include the date of the missed exam; an illness preceding an exam does not constitute an excused absence. Also, simply being seen by a health care professional does not constitute an excused absence. Furthermore, self-documentation of illness is not sufficient support to excuse an absence. Excused absences will not be given unless documentation as described is provided. If you become ill, keep in mind that the University Health Center will not provide medical documentation.
It is the University's policy to provide accommodations for students with religious observances conflicting with exams, but it is the your responsibility to inform the instructor in advance of intended religious observances. Written notice must be provided immediately upon an exam date being announced or confirmed in order for an absence to be excused. If you have a conflict with one of the planned exams, you must inform us prior to the end of the schedule adjustment period.
For missed exams due to excused absences, the instructor will arrange a makeup exam. However, unless immediate notice is given as early as possible of the reason for any missed coursework, an excused absence may not be granted. If you might miss an exam for any other reason other than those above, you must contact the instructor in advance to discuss the circumstances. We are not obligated to offer a substitute assignment or to provide a makeup exam unless the failure to perform was due to an excused absence.
The policies for excused absences do not apply to project assignments. Projects will be assigned with sufficient time to be completed by students who have a reasonable understanding of the necessary material and begin promptly. In cases of extremely serious documented illness of lengthy duration or other protracted, severe emergency situations, the instructor may consider extensions on project assignments, depending upon the specific circumstances.
Students with DisabilitiesStudents with disabilities who have been certified by Disability Support Services as needing any type of special accommodations should see the instructor as soon as possible, during the schedule adjustment period. All arrangements for exam accommodations as a result of disability must be made and arranged with the instructor at least three business days prior to the exam date, or accommodations will not be made.
The Campus Senate has adopted a policy asking students to include the following statement on each examination or assignment in every course: "I pledge on my honor that I have not given or received any unauthorized assistance on this examination (or assignment)." Consequently, you will be requested to include this pledge on each exam and project. Please also carefully read the Office of Information Technology's policy regarding acceptable use of computer accounts.
Programming projects are to be written individually, therefore cooperation or use of unauthorized materials on projects is a violation of the University's Code of Academic Integrity. Any evidence of this, or of unacceptable use of computer accounts, use of unauthorized materials or cooperation on exams or quizzes, or other possible violations of the Honor Code, will be submitted to the Student Honor Council, which could result in an XF for the course, suspension, or expulsion.
Violations of the Code of Academic Integrity may include, but are not limited to:
If you have any question about a particular situation or source then consult with the instructors in advance. Should you have difficulty with a programming assignment you should see the instructional staff in office hours, and not solicit help from anyone else in violation of these rules.
It is the responsibility, under the honor policy, of anyone who suspects an incident of academic dishonesty has occurred to report it to their instructor, or directly to the Honor Council.
Every semester the department has discovered a number of students attempting to cheat on project assignments, in violation of academic integrity requirements. Students' academic careers have been significantly affected by a decision to cheat. Think about whether you want to join them before contemplating cheating, or before helping a friend to cheat.
You are welcome and encouraged to study and compare or discuss their implementations of the programming projects with any others after they are graded, provided that all of the students in question have received nonzero scores for that project assignment, and if that project will not be extended upon in a later project assignment.
Right to Change InformationAlthough every effort has been made to be complete and accurate, unforeseen circumstances arising during the semester could require the adjustment of any material given here. Consequently, given due notice to students, the instructors reserve the right to change any information on this syllabus or in other course materials.
