Policies

Communication

We will be using Piazza for discussions outside of class. Rather than emailing general questions to a professor or TA, we encourage you to post your questions on Piazza, so everyone can benefit from the answer and any discussions around it.

Grading

For each exam (and only for the exams), we will curve the scores (upward only) to a normal distribution.

We translate your final class percentage into a letter grade as follows:

The total points possible are allocated as follows:

Note that there are three exams: we will drop your lowest exam score.

Electronics

Studies show that multitasking with electronics in the classroom can have a significant negative impact not just on your understanding, but also on the learning of students around you. Hence, aside from the clickers discussed below, students may not use any electronic devices in lecture (no cell phones, laptops, tables, etc.) without explicit permission in writing from the instructor. Students are expected to take notes, but to do so manually (e.g., with pencil and paper). Exceptions will be granted in accordance with university guidelines for accessibility concerns.

Participation

Attendance is required (if not always strictly recorded). You will be responsible for all materials presented in lectures and recitations. You should not expect that all lecture or recitation materials will be given to you in written form. We strongly encourage you to be active in class discussions, in recitation, and Piazza, but your actual participation grades will be based on the quantitative measures described below.

Recording (audio or video): Students may not record lectures or recitations without explicit permission in writing from the instructor. Violations will result in your failing the course. Exceptions will be granted in accordance with university guidelines for accessibility concerns, but even then such recordings may not be shared publicly or privately and must be deleted at the end of the semester.

Recordings of course sessions, when provided, are provided solely for educational use by students enrolled in the course and may not be distributed to any other person or posted on the internet without the express written permission of the course instructor.

Class participation score and quizzes: Students will use “clickers” to answer both quiz questions and class participation questions. Most classes will begin with 2-3 quiz questions about the previous lecture. These will be answered on your own and graded for correctness. There will also be participation questions during the lectures. For these, you will typically be allowed to confer with a neighbor before answering. These questions are designed to help you figure out if you’re following the material, and will not be graded for correctness. Overall, there will typically be 4-5 questions each class. To lower the pressure and to account for inevitable conflicts that cause you to miss class, we will allow you to get 20% of quiz questions wrong without penalty and to miss (i.e., not answer) 20% of the participation questions. In other words, if you answer 80% of all quiz questions during the semester correctly, you will receive the full 5% quiz score; if you answer 80% of all participation questions (correctly or not), you will receive the full 5% participation score. We reserve the right to modify the participation score based on classroom behavior (e.g., disruptive behavior in the classroom that interferes with student learning may result in the score going down; particularly helpful posts on Piazza may result in the score going up).

Recitation participation score: Many recitations will involve a group activity that you should be able to complete during recitation (the goal is not to give you more homework!). If you complete the activity by the end of recitation, you will receive two points. If by the end of recitation, you can show us that you made substantial progress on the activity, then you will receive 1 point. Otherwise, you will receive 0 points. We will drop the lowest 20% of your recitation activity scores.

Resources

Before each lecture, we will endeavour to provide you with a list of lecture notes, which will include a variety of questions you should be able to answer by the end of the lecture. The notes are not a substitute for attending lecture; they are merely intended to help you focus on important topics that the lecture will cover. Note that material that does not appear in the lecture notes is still fair game for homeworks and exams.

Most lectures will be accompanied by required and optional readings. The former provide additional detail on the lecture topic, and so they should be helpful for the associated homeworks and exams. Optional readings provide further depth and/or explanation, but material in optional readings will not be required for homeworks or exams.

Late Days for Homework

Late days interfere with the ability of course staff to quickly turn around assignment grades and solutions. The problem is we cannot give out solutions or graded assignments until everyone has turned in their work. However, we understand that unforseen circumstances may arise. Thus, each student has a budget of 4 late days for the semester, with a maximum of 2 that can be used toward a single homework. To use a late day, you must send the course staff a private Piazza message before the official deadline. If you ask to use a late day after the deadline, it will be too late. Once your budget of late days has been used up, no further days will be granted, and late homework will be marked as a zero.

The only exceptions will be for family emergencies or exceptional circumstances, such as hospitalization. We do not offer exceptions for personal scheduling issues such as interviews, class load, etc.

Ethics and Cheating

The course staff will treat all students ethically and fairly. We, in turn, expect the same from all students.

Any lapse in ethical behavior will immediately result in −1,000,000 points, as well as be immediately reported to the appropriate university disciplinary unit. Really. No matter what. The course staff looks at students who cheat or plagiarize as far beneath someone who fails the course.

This course will follow CMU’s policy on cheating and plagiarism. Note that the policy gives several examples of what constitutes cheating and plagiarism. If you have any questions, you should contact the instructors.

Students should behave ethically. This means obeying the law, but that is not enough. Behaving ethically means you avoid activities that do harm or may do harm to people, the environment, or other computers. In short, don’t be a nuisance.

Note just because you can do something (or you read about others doing it) does not make it ok. For example, scanning a network may not be illegal (I am not a lawyer, so I shy away from definitive statements). However, scanning can crash computers. For example, we know of several very popular commodity-grade IP cameras that crash when you scan them. Sure, the camera software is buggy. But is there any reason for you, not being a professional, to crash a camera monitoring a baby? Launching exploits, “testing” the security of a system without explicit permission from all necessary parties, and so on are all unethical for the purpose of this course.

Collaboration. Students are encouraged to talk to each other, to the course staff, or to anyone else about any of the assignments. Assistance should be limited to discussion of the problem and sketching general approaches to a solution. Each student must turn in his or her own solution, derived from his or her own thoughts. Course staff may verify a student did the prescribed work by asking for a verbal explanation, and failure to correctly re-explain a submitted solution is considered a strong indication of cheating.

Work Life Balance

Take care of yourself. Do your best to maintain a healthy lifestyle this semester by eating well, exercising, avoiding drugs and alcohol, getting enough sleep and taking some time to relax. This will help you achieve your goals and cope with stress.

All of us benefit from support during times of struggle. You are not alone. There are many helpful resources available on campus and an important part of the college experience is learning how to ask for help. Asking for support sooner rather than later is often helpful.

If you or anyone you know experiences any academic stress, difficult life events, or feelings like anxiety or depression, we strongly encourage you to seek support. Counseling and Psychological Services (CaPS) is here to help: call 412-268-2922 and visit their website. Consider reaching out to a friend, faculty or family member you trust for help getting connected to the support that can help.

If you have questions about this or your coursework, please let us know.
