CMSC 330, Fall 2015
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 dynamic, scripting (e.g., Ruby, Python) functional (e.g., OCaml, Haskell, Scheme), logical (e.g., Prolog), and concurrent/parallel (an aspect of many languages). Language features such as formal syntax, scoping and binding of variables, higher-order programming, typing and type polymorphism, and concurrent language features will be 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 Grace Cluster www.grace.umd.edu. Accounts are distributed via the grades server, grades.cs.umd.edu. Log in with your OIT account; if you do not have a OIT 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 (by the submit server). 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.
Grades will be maintained on the CS Department grades server. You can always see your current grade here.
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:
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. But: It is very likely that 90 and above earns an A, 80-90 earns a B, 70-80 earns a C, etc.; the curve will only lower the cutoffs, not raise them. 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. We will define good-faith attempt as achieving at least 20 percent on the submit server for each project. To obtain these points you may submit solutions past the late deadline.
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 11:59pm 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 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 both on-time & late, your project will received the maximum of the 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 deadline will be graded. 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 (or, very few). 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 may 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.
Do not share or publicly post your project solutions on-line; doing so constitutes a violation of academic integrity. This issue is discussed in greater detail below.
Quizzes will be given at various times during the semester in discussion section. Quiz dates will be announced in lecture shortly in advance. No makeup quizzes will be given under any circumstances. The lowest quiz grade will be dropped.
Laptops in class
In general, we discourage the use of laptops in class. Not only are they a distraction for their user, they are a distraction for students around that user. For those who wish to use laptops to take notes, please sit in the back two rows of the lecture hall. Elsewhere, laptops must remain closed.
Meet your professor
You have the opportunity to earn 1 point of extra credit by merely coming to office hours to or another arranged time and introduce yourself to your professor. You can chat about academic goals, the course, or anything else that seems interesting.
Outside-of-class communication with course staff
We will interact with students outside of class in primarily three ways: in-person during office hours, electronically via the web forum and course web page, and electronically via e-mail. The large majority of communication should employ the first two methods, reserving e-mail for personal (presumably rare) circumstances.
Personalized assistance, e.g., with programming assignments or exam preparation, will be provided 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. Office hours for the instructional staff will be posted on the course web page a few days into the semester.
Additional assistance will provided via the Piazza web forum. You may use this forum to ask general questions of interest to the class as a whole, e.g., administrative issues or project clarification questions. The course staff will monitor piazza on a daily basis, but do not expect immediate answers to questions. Please do not post publicly any information that would violate the university academic integrity policy (e.g., project code or test cases).
Piazza allows students to post private questions that are only visible to instructors. Please use this feature if you wish to ask specific questions concerning your project solutions. Generally it will also be helpful to submit your current project code to the submit server, so instructors & TAs can try running your code on their machines before answering your questions.
Personal e-mail to instructors or TAs should be reserved for issues that cannot be handled by the above methods.
Important announcements will be made in class or on the class web page, and via piazza.
Any student who needs to be excused for an absence from a single lecture, recitation, or lab due to illness shall:
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 excused so long as the absence is requested in writing at least 2 days in advance and the student includes documentation that shows the absence qualifies as excused; a self-signed note is not sufficient as exams are Major Scheduled Grading Events. For this class, such events are the final exam, and the two midterms, which will be given in class on the following dates
For medical absences, you must furnish documentation from the health care professional who treated you. This documentation must verify dates of treatment and indicate the timeframe that the student was unable to meet academic responsibilities. In addition, it must contain the name and phone number of the medical service provider to be used if verification is needed. No diagnostic information will ever be requested. Note that simply being seen by a health care professional does not constitute an excused absence; it must be clear that you were unable to perform your academic duties.
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. If you have a conflict with one of the planned exams, you must inform us prior to the end of the first two weeks of the class.
For missed exams due to excused absences, the instructor will arrange a makeup exam. 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.
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.
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 (the first two weeks of class). Please provide DSS's letter of accommodation to the instructor at that time.
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; later requests (including retroactive ones) will be refused.
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. Both the person receiving assistance and the person providing assistance are in violation of the honor code. 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.
Course EvaluationsIf you have a suggestion for improving this class, don't hesitate to tell the instructor or TAs during the semester. At the end of the semester, please don't forget to provide your feedback using the campus-wide CourseEvalUM system. Your comments will help make this class better. CourseEvalUM is scheduled to be open between Tuesday, December 1 and Sunday, December 13, but this is subject to change by campus.
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.
