Scenario
Ben Bitdiddle is an M.Eng. student, and he has been appointed as a 6.006 TA. On Wednesday 3/2, Ben needs to post Problem Set 2, due in one week on 3/9. The assignment has 2 theory problems, and one problem that requires coding. Ben prepared a description in PDF format. For the programming problem, he also prepared some input test cases, and Python script to automatically test the students’ submissions. Ben logs on the site, creates a Problem Set, and uploads all files in the right places. He uploads the TA solution, as well as a broken solution, to make sure that his automated tests work as intended. Once Ben is pleased with the results, he makes the Pset visible to students.
Alyssa P. Hacker is a sophomore living in Random Hall. Alyssa checks the site and notices the announcement that PS 2 is out. She reads the PDF description, and finds an error. She e-mails Ben, who acknowledges the error. Ben must upload a revised PDF description, and make an announcement that would be visible to anyone who tries to submit a solution.
Alyssa finishes the coding problem that evening. She submits her Python program on the website, and finds out that her solution takes too much time to run on the automated tests. She removes her debugging checks, and re-submits. The site assures her that she has passed the automated tests, so Alyssa starts working on the write-up. Later that night, she submits her PDF write-up.
PS 2 is due on Wednesday 3/9 at midnight, and the server chugs through the usual last-minute submission rush. Next afternoon, Ben prints out students’ submissions, and starts grading them. Wednesday late at night, he finishes grading. He logs on the submission site, and goes through the stack of psets in front of him, entering the grades on the site. After he’s done, he makes all the grades public.
Alyssa goes online on Sunday, and sees her grade for the problem set posted. She also checks the distribution of grades for the problem set, and her overall grade.
Louis Reasoner is a senior who recently settled on Course 18C, and is trying to graduate. Prof. Smith signed an Add Form for Louis, and granted him an extension for the two problem sets. Ben pointed Louis to the submission site. Louis signs up for an account, registers for the class, and prints out the two problem sets. He eventually submits everything, after having gotten an undisclosed amount of help from Alyssa.
Monday morning, Ben goes through the late submissions, from students who were granted deadlines. He prints them out, grades them quickly, and enters the new grades on the site.
