|Description||A technical introduction to the fundamentals of programming with an emphasis on producing clear, robust, and reasonably efficient code using top-down design, informal analysis, and effective testing and debugging. Starting from first principles, we will cover a large subset of the Python programming language, including its standard libraries and programming paradigms. We will also target numerous deployment scenarios, including standalone programs, shell scripts, and web-based applications. This course assumes no prior programming experience. Even so, it is a fast-paced and rigorous preparation for 15-122. Students seeking a more gentle introduction to computer science should consider first taking 15-110. NOTE: students must achieve a C or better in order to use this course to satisfy the pre-requisite for any subsequent Computer Science course.|
At the end of the course, students should be able to:

Instructor Office Hours:
TA Office Hours (After Midterm2 / During TP Season):
Piazza Virtual Office Hours:
Piazza is monitored by TA's daily at all (reasonable) hours of the day.
When posting on Piazza, remember to make your post private! Public posts by students are not allowed.
Scheduled weekly by recitation TA's.
Homework Booster Sessions:
Academic Development Walk-in Tutoring:
This is a great resource provided not by 15-112 but rather by Academic Development in support of 15-112.
(*): Friday Writing Sessions:
Wednesday recitations meet in the rooms listed below. All Friday writing sessions, however, meet in the Gates 5th floor clusters. You are required to attend during your scheduled time, but may attend in any of the three cluster rooms unless directed otherwise by faculty or staff.
15-112 can be an intense course, but it becomes much more manageable if you use the course resources well.
These resources include:
|Every required software package we use is available for free on the web. This includes:|
|Participation with earnest effort in this course is required and consists of the following activities:
Any material covered in lecture, in recitation, in assigned readings, or in homework assignments may be included in any future homework assignment, quiz, or exam.
Midsemester and Semester grades will be assigned using a standard scale, as will each homework, quiz, midterm, term project, and final, as such:
A: 90 - 100
B: 80 - 89
C: 70 - 79
D: 60 - 69
R: 0 - 59
Note that graduate students will be assigned +'s and -'s according to the following scale (generalized across letter grades):
The course instructors may choose to change the scales at their discretion. You are guaranteed that your letter grade will never be lowered as a result of changing scales.
Semester Grade Cap Policy
In all cases, your semester grade is capped at 10 points above the highest score you receive on the course's proctored events -- that is, on your semester quiz average, on midterm1, on midterm2, or on the final exam. For example, if your raw semester average is 83, but your highest proctored score is a 65, then your semester score is capped at 75 and you would receive a C as your semester grade.
Alternate Minimum Grading (AMG) Policy
This AMG policy is available to everybody, but is designed specifically for those students who struggle in the first part of the course and then through sustained hard work and dedication manage to elevate their performance in the latter part of the course to a level that merits passing with a C, even if their Standard Grade might be lower than that.
In addition to Standard Grading as described above, we will separately compute your grade using an Alternate Minimum Grading (AMG). Students do not sign up for AMG. Every student will be considered both for Standard Grading and AMG, and their semester grade will be the higher of the two (where the highest grade via AMG is a C).
To compute your Alternate Minimum Grade, first use the following to compute your raw score:
Unlike the Standard Grade, effort is heavily factored into your AMG score. To qualify for AMG you must put forth sustained effort, which means meeting the following requirements:
Writing Session exercises are released no later than Tuesdays before lecture. These exercises are designed to help you learn the current week's material well, so that you have a solid foundation heading into the solo homework. You may work collaboratively on these exercises. There is nothing to submit, either. Instead, you will sit for a timed and proctored Writing Session in your assigned lab on Friday. In this time, you will solve a selected subset of the assigned exercises (or similar exercises) without access to any notes or other supports, though you will have access to a Python IDE and an autograder.
Homeworks are released on Tuesdays before lecture and are due on Saturdays at 8pm. These can contain a mix of coding exercises (reading, debugging, and writing code) and written exercises. They generally assess the material taught the week they are released, and take several hours to complete. We strongly encourage you to start the homeworks early, as soon as you have mastered the material for the week's Writing Session.
Homeworks are entirely solo. See the "Academic Integrity" section below for more details. That said, you always have access to extensive help provided by the TA's and course faculty.
Programming assignments will be graded based on style (modularity, effective use of data abstraction, readability, commenting, etc.) and functionality (correctness and efficiency of the program on all possible test inputs). Your code should be properly annotated with comments that are well-placed, concise, and informative. Your assignments will be graded by TA's, by automated graders, and at times by the course faculty.
The Term Project will take place over three weeks at the end of the semester. You will design and build a program of your choosing with the guidance of a mentor TA. More information can be found in the Term Project Assignment writeup.
15-112 is and will remain a rigorous and challenging course.
However, we are always seeking ways for you to achieve rigor and excellence
while minimizing your time-on-task and stress. To that end, we are
providing optional HW Booster Sessions this semester.
The goal of a Hw Booster Session is to give you a boost, to help you converge towards understanding and completing the hw, but only after you have invested considerable time, energy, and earnest focused effort on the hw.
Hw Booster Session Structure:
Quizzes will be given most weeks, generally in lecture on Tuesday. Quizzes generally focus on material from the previous week and the previous homework, though any prior material may appear as well.
There will be two midterm exams, weighted as indicated above, given in class as noted in the course schedule.
There will be a standard 3-hour final exam, weighted as indicated above, during the final exam period at the end of the semester.
Unless otherwise noted, all homework exercises are solo, meaning that you must not collaborate with anyone in any way. Examples of cheating on homework include:
Remember: you always have access to extensive help provided by the TA's and course faculty. We strongly encourage you to use this support!
Homework Booster Session:
Here are some cheating-related items for Hw Booster Sessions:
The Term Project has its own policy, allowing for certain kids of productive collaboration basically so long as it is carefully and properly cited and otherwise follows the rules as clearly described in the term project writeup. Still, you will only be graded on your original contributions, and those must be truly and entirely yours.
Assessments (Writing Sessions, Quizzes, and Exams):
Examples of cheating on assessments (Writing Sessions, Quizzes, and Exams) include:
If you are repeating 112, your prior work in this course is treated just as anyone else's work -- that is, you may not consult it. This is to promote the best possible learning, and using your prior homework answers or term project solutions will only hurt in that regard, and so is entirely disallowed.
Programs are naturally structured, which makes them much easier to compare than handwritten work or typed essays. We run an automated plagiarism detection system on all assignments to detect copied code. Here is a short video demonstrating one of several detection methods we use. In short: if you copy code, we will be able to tell. Don't copy code!
Penalties are decided by the course faculty, and can vary based on the severity of the offense. Possible penalties include:
To end this section on a more positive note, you should know that we put a high premium on honesty. Of course, it's by far the best to always be honest and not have an Academic Integrity violation in the first place. That said, if you do get into an Academic Integrity situation, then the sooner and more completely you tell the entire truth, by far the better it is for you and for everyone else involved. The bottom line: If you regret a lapse in judgment, it is always better to let us know right away, to come clean and be honest and truthful. You will feel better about it, as will we, and it may perhaps result in a better outcome for you as well.
Here is this semester's
Extension Request Form.
That said, in general, due to the scale of the class, we cannot give individual extensions on assignments or assessments.
However, there are a few exceptions:
In general, all homework is due at the assigned date and time.
However, we understand that life can sometimes get in the way. Therefore, we provide 2 Grace Days for homework assignments. These can be used to submit homeworks up to 24 hours late with no penalty.
You may only use one grace day per homework.
You do not submit a request to use a Grace Day -- you simply submit
your homework after the posted deadline, and autolab automatically
counts that as a grade day if one is available for you.
We strongly urge you not to use these grace days immediately; try to save them for unforeseen events. Note that grace days may only be used on homeworks, and may not be used on writing sessions, quizzes, or exams.
Important note: if you are out of grace days, then any late submissions to Autolab will receive 0 points.
Additionally, no late/make-up writing sessions, quizzes, or exams will be administered, except in the cases covered under the Extensions policy. Approved missed quizzes will be excused; approved missed writing sessions or exams will be taken at the earliest possible date as approved by course faculty.
|Regrade Requests:||We occasionally make mistakes while grading (we're only human!). If you believe that you found a mistake which you would like us to correct, please submit a regrade request using this form. Regrades must be requested within three weeks of the time when the contested grade was released. Note: regrade requests will result in the entire problem being regraded, not just the possibly-incorrectly-graded part.|
|Formatting Errors:||Misformatted homework in general cannot be graded by our autograder, and as such may receive penalties, which can range from -5% to not being accepted at all. Therefore, be sure to submit your homework early (you can submit repeatedly, we only grade the last submission) to be sure you do not have obvious formatting errors. Errors can be detected by checking your Autolab grade and feedback a few seconds after submitting.|
|Electronics:||Research has shown that devices can greatly detract from student learning. Therefore, unless otherwise noted or without explicit permission from the instructors or TA's, students may not use phones, laptops, or other electronic devices in lecture, recitation, lab, or any other faculty-led or TA-led course events. You may still take notes during lecture, of course, but do so with pen and paper. This policy is meant to help all students focus, as electronic devices are distracting not only for the user, but also for the students surrounding them.|
|Recording:||Students may not record audio or video of lectures or recitations or any other faculty-led or TA-led course events without explicit permission in writing from the instructor or the TA in the instructor's absence. Exceptions will be granted in accordance with university guidelines for accessibility concerns, but even then such recordings may not be shared publicly or privately.|
|We gladly accommodate students with special needs (as approved by the Office of Disability Resources (ODR), as explained here). If you are eligible for accommodations, please deliver the appropriate form to the instructors in the first two weeks of the semester. If you need to acquire the form, contact Catherine Getchell, Director of Disability Resources.
Extended Time: students who receive Office of Disability Resources (ODR) approved extended-time on assessments will need to request proctoring from the ODR for each quiz and exam. The course instructors will send you a list of examination days at the beginning of the semester so that you can request proctoring in bulk. Extra-time assessments must take place on the same day as the in-class assessment.
Important: to use extended-time, you must attend the Office of Disability Resources (ODR) proctored quiz or exam and not the normal-duration quiz or exam. You do have the option of attending the normal-duration quiz or exam, but then you will have to complete it in the assigned time (without extended-time). If you are in lecture during a normal-duration quiz when you plan to take the extended-time quiz, you may remain in the room and work quietly on other materials (without electronics), or you may leave the room for the duration of the quiz.
|Auditing:||We have found that students who audit 15-112 do not tend to succeed, as they generally cannot dedicate the requisite time and focused discipline to the course. Therefore, auditing will only be allowed in exceptional circumstances, and must be approved by the course instructors first. Rather than auditing, in some cases you may take the course as Pass/Fail instead. This still is not ideal basically for the same reasons, but history suggests that it is a better option in some cases (say, for graduate students who want to learn how to program but already have an over-full load of graduate courses). Note: you may not take the course Pass/Fail if you plan to use 15-112 as a prereq.|
|Waitlist:||If you are on the waitlist, don't panic!. Most waitlisted students get into the course eventually. Just be sure to fully participate from day one as though you were enrolled. Attend lecture and recitation, submit the assignments, and stay involved. If you are still not enrolled at the beginning of the third week, contact the course instructors and they will help you find a section with open seats.|
We care very much about your well-being and
happiness. Yes, CMU students (and faculty) work hard, sometimes very hard.
But we must keep our balance and always attend to our well-being and happiness.
That comes first, academics follow. So be sure to get enough sleep, eat
right, exercise regularly, and attend to your well-being and happiness.
Here is a list of ideas that might help.
Also, please know that we do care about you and take your well-being seriously. We want to help you learn while minimizing stress. Towards this end, we are working to reduce the workload of the course as much as is possible, while still meeting the learning goals of the course. If you have any ideas or feedback towards reducing the workload or student stress, or improving the course in general, please let us know!
Finally, if you are feeling overly stressed, or anxious, or unhappy about your performance or your general experience in this course: please come talk to us. We will listen. We are here for you and we will try to help.
Addendum: Here is a great summary of many CMU Student Support Services.
