A7, final-exam scores, course grades posted

A7, final-exam scores and course grades have been posted to CMS and to FacultyCenter (where they will propagate to transcripts shortly). The information available about how course grades were determined has not changed from that posted on the "Grading" page on the course website.

To see your grade for the course, look at the top of the CMS CS1110 page; right under the title, you'll see text that says "Show Final Grade:" Click on the red "Show" to reveal your grade for the course.

Because of the closure of the homework handback room for the semester, it's unfortunately not possible to view your final exam until next semester (Fall 2016).

Game+OOP Opportunity

Dear students of CS 1110, We are a group of people taking CS 6360 (Educational Technology), and as part of the class we have been working on a game that tries to teach object-oriented programming concepts to learners with a little bit of programming experience. We're looking for volunteers to play the game so we can collect data, and we thought that students in CS 1110 might be a good approximation of our target audience. We would be extremely grateful if you could check out our project! If you are reviewing OOP concepts for the 1110 final, planning on taking CS 2110, or are just interested in trying out an educational game, you might find it worthwhile.

Prelim 2 (re-)grade guidelines

        You can pick up your graded prelims in your section this week
(exception for grad students: see bottom of this announcement).
You can also pick them up from section next week, but the regrade deadline
will have passed (see below).

APPROXIMATE grade guidelines:
A: 31-34
B: 25-28
C: 19-23

Regrade request procedure:

On a separate sheet of paper write your name, netid, section time and location.
Then write down your grading issue on this sheet.
DO NOT WRITE ON THE EXAM ITSELF.
STAPLE this sheet to the front of your exam.
Hand the sheet+exam packet to Prof. Van Loan at the end of lecture on Thursday May 5th.
Making reference to the grading guide (available on CMS) in your statement would be wise.

Requests for makeups for the final exam due May 4, 6pm

See the exams page for the petition template, which explains what to submit to CMS assignment "Final Exam conflicts" if you need to request a makeup. Makeup requests are due May 4, 6pm (the exam itself is Wednesday May 18, 7pm-9:30pm).

Q: I already talked to you by email/in person about a makeup. Do I need to do this "assignment"?
A: Yes, you MUST do so. (We need to centralize the information collection process in order to manage.)

Q: If I have two exams back-to-back or two exams within 24 hours, can I have a makeup?
A: Sorry, no. The rules are that it's 3 exams within a 24-hour window that trigger a makeup.

Q: Will the makeup be earlier than the regular exam?
A. No-ish (high probability the answer is "no")

What is going on with where the prelims are

For those who are curious, here is more than you ever wanted to know about what is going on with the prelims being moved around to various secure (un)disclosed locations.

The issues are as follows:

  • The homework handback room doesn't have the staffing capacity to have hundreds of CS1110 students coming by during a short period of time (not to speak of the other large CS courses also contributing traffic). The CS1110 staff themselves are under similar constraints.
  • We want to get the prelim regrade requests processed as soon as we can, and would ideally fold them back in with the other uncollected prelims.
  • A number of students could not find their prelim at their section. It appears there were two causes: (a) The student circled the wrong section on the front page, or didn't circle a section at all, or (b) The course staff misfiled the prelim.

So: we made the prelims available in lab section this week, thus using distributed distribution (ha) to lessen the load on the handback room. Grad students were directed to the handback room.

Then, in order to track down missing prelims, we needed to reclaim any exams from the homework handback room Wednesday before the close of business in order to be able to search through the whole lot and, in addition, make sure there wasn't any possibility of exams getting picked up without us knowing about it (i.e., lost exams turning out to be picked-up exams).

Now (Thursday), we are finalizing the process of tracking down any remaining missing prelims among the prelims that we have, and manually (!!) checking all indicated student sections for accuracy [there were a lot of mistakes made by students in this regard. People who do this: you are making kittens weep! Please stop it!.] to make sure we can route the prelims to the correct sections.

And, if we can get the regrade requests done in a timely fashion, we can put the regraded exams in with all the other exams we have and not need an additional return mechanism for them.

Finally, we still have to be mindful of not overwhelming the homework handback room staff, so we have to decide whether we will again route the uncollected exams to lab sections for another round, or instead do something else.

And yes, at least one of your professors has never, ever been accused of “not overthinking it”.

A2 grading: why -2 points for not exactly matching output in capitalization does (not) matter

Don't think of two points off as "10 out of 12 is a B (83%)", because we don't. We think of it as "just two points off: a small penalty to make you aware of something you should fix later on, but not a big deal in the scheme of things". If your only deduction is this two points, you are doing fine. Code must produce exactly, including spacing and capitalization, what the caller — which might be a program — expects.

Imagine another program is calling your function, and is running something like "if s[14:] == 'Make a U-Turn'", since that's what the handout led them to expect your code to do. If your code instead prints "Make A U-Turn" (capitalizing the 'A') , their code is going to miss the U-turn, with perhaps disastrous consequences.

Prelim 1 places, what to bring, studying, and how labs/office hours that week are affected

What room you go to for the exam depends on your last name (unless you are taking a makeup prelim or have extra time, in which case you will have been contacted separately by Course Administrative Assistant Megan Gatch).

  • 119 Baker Lab (A-Chem)
  • 135 Baker Lab (Chen-Fao)
  • 219 Baker Lab (Faq-Hub)
  • 335 Baker Lab (Huc-Lans)
  • 200 Baker Lab (Lant-Z)

Bring your Cornell ID and something to write with. No calculators, no laptops, etc. are to be used.

To help you study, solution sketches for labs 1-4 and solutions for A1-A3 are now posted. Once the due dates for Lab 5 and A4 pass, those solutions will also be posted.

Because of the prelim, there is no new lab for the week of March 14th. The Tuesday labs will be staffed and you can treat them as drop-in office hours. The Wednesday labs are cancelled and will not be staffed at all.

There will be no office hours or consulting hours Tuesday 4:30pm through Saturday.

A2: print vs return

Consultant Fred Callaway writes the following:

It's very important to understand the difference between the following two functions:

        def add_one(x):
            return x + 1

        def print_plus_one(x):
            print x + 1
        
The first is a fruitful function. The second is a void function or a procedure. The first function doesn't "do" anything; it just gives you a new value (it returns). The second function actually does something (it prints 4); but it doesn't give anything back.
        if __name__ == '__main__':
            add_one(3)  # no effect
            print_plus_one(3)  # 4 is printed to the screen

            four = add_one(3)
            print four  # 4 is printed to the screen

            five = print_plus_one(4)
            print five  # "None" is printed to the screen

            print_plus_one(add_one(3))  # 5 is printed to the screen
        
A common pattern is to have one function that prints things, but doesn't return anything, and several helper functions which don't print anything, but do return things. Siri.py is an example of this. One function only prints, and the other only returns. It is important that you follow the directions when deciding which function in Siri.py should return and which function should print.

Two things. I skipped over the first half of the slide show feeling that it just clarified the import/module business that was done last week. (Check it out though!)

More installation to enable graphical programs

Now is the time to follow steps 4 and 5 in the Python installation instructions ("Adding necessary packages to Python" and "Test the necessary packages"), so you'll be set to run the graphical python programs we discussed in class.

New office hours added where we'd like to prioritize those without prior programming experience

We've been able to add another regular set of office hours, which means there's an additional two hours on Friday before A1 is due. See the Staff page.

We'd like to prioritize students who have no prior programming experience for tomorrow's Friday 3:30-5:30pm hours. So please use other hours or Piazza for help if you already have some prior programming experience. (Again, see the Staff page for the full list.)

Lab 02 due date extension

The Lab 02 due date is extended to the end of consulting hours on Monday the 22nd. Due to unusual scheduling because of break, we will have staff on hand during the Wed Feb 17th lab hours, so you can also get checked off there, regardless of what section you are registered for. (The Tuesday Feb 15th labs will not be staffed, since it's break.)

A1 is still due on Friday the 12th, and we recommend you get help with sections 1, 2, 4 and 5 of the lab beforehand if you need it.

What to do if you are an undergraduate with a "section problem"

This announcement is about what to do if you are an undergraduate in CS 1110 but have a "section problem".

Think about taking CS 1112 (Matlab) which for many students is a perfectly fine substitute for 1110. Both courses prepare you for CS 2110 (Java), the next course. If you just need one computing course to enhance your career ambitions, then Matlab is almost always just as good, if not better than Python. CS 1112 has plenty of open seats.

Think about taking CS 1110 next semester or in the summer.

Think about taking CS 1133 next semester.

Think about StatSci 4060. This is an excellent 2-credit Python course that works if you are headed into the business sector or any of the sciences.

If none of these alternatives are appealing, then be aware how things might play out in CS 1110. Recall that

  • Sections 201-213 are "real sections" because they meet.
  • Section 214 is a "phantom section" because it doesn't actually meet.

If you are registered in a real section that you cannot attend because of a schedule conflict, then drop/add your way into the phantom section. This might help one of your classmates and it doesn't hurt your chances of getting into a real section of your choice.

If you are registered in the phantom section then you will have to stay there until a spot opens up in a real section that works for you. We cannot predict whether or not this will happen. While in the phantom section undergraduates are still required to complete the lab assignments and to have then checked off by a member of the course staff, but must do so at consulting hours (you cannot attend a lab you are not registered for).

Some Facts to help you understand the big picture:

  1. There are about 50 graduate students in the course and they are all required to take the phantom section.
  2. Real sections have a capacity of 40 students so there is a total lab capacity of 13*40 = 520.
  3. The overall enrollment is very close to the fire marshall limit = 287+287 = 574
  4. There are enough seats in the lab to accommodate all undergraduates.
  5. You are not allowed to attend a given lab unless you are formally registered for that lab.
  6. We are unable to offer more real sections and unable to accommodate more than 574 students overall.

Lab 01 ready for you to start if you like

The Lab 01 handout and accessory file have been posted to the "Labs" section of the website, so you can start now if you like! We definitely recommend at least reading the lab handout before you come to your lab section.

"Discussion sections" (labs) do not start until Feb 2 and 3

The "discussion sections" (henceforth labs) for CS1110 do not start until Tuesday Feb 2/Wednesday Feb 3rd.
If you haven't been able to enroll in the class or in your preferred section because of at-capacity sections, please still come to the first day of lecture (Thursday January 28th); we will discuss possible solutions then.

All (and only) masters and PhD students should enroll in the TBA section (a.k.a. lab) 214

All masters and PhD students should enroll in the TBA section CS 1110-214 (18823). This "section" will never meet: masters and PhD students neither attend lab sections nor submit lab exercises. Undergraduates should (eventually) enroll in one of other sections, CS 1110-201 through CS 1110-213.
