  • Comedy at Harvard


    While Harvard does offer a few courses on the topic — acting workshops and more academically minded examinations of comedy by Shakespeare and other playwrights — most of the action occurs outside the classroom, in student-driven extracurricular groups that have made the University something of a comedic training ground.

    Some observers, including alumnus John Lithgow, have credited the bright minds and ready wits Harvard turns out with making an indelible imprint on American comedy, a style the actor once described as swinging between “ironic-brainy and daffy-stupid.”

  • Teaching Academic Honesty in CS50 - SIGCSE 2020


    A talk for the 51st ACM Technical Symposium on Computer Science Education (SIGCSE '20). Paper at Slides at #SIGCSE2020

    We aspire to teach academic honesty in CS50 at Harvard University not only by addressing academic dishonesty when it occurs but by addressing it before it does. By way of communication, course- and campus-wide awareness of policy, just-in-time prompts, interventional conversations, and problem sets have we tried to preempt submission of plagiarized work. But few interventions have had significant or lasting effects on the number of instances thereof. Most impactful has been the addition of one sentence to the course's syllabus, a regret clause that encourages students to come forward within 72 hours of some dishonest act on their part, before the course itself is even aware. While we might zero the work in question in such cases, we commit to not escalating the matter further to the university's honor council, where the outcome might instead be admonishment, probation, or even required withdrawal from the university itself. We instead advise students on how best to move forward and connect them as needed with support structures on campus for academics and mental health. Since 2014 have 89 students invoked the clause, between 1% and 3% of the course's student body each year.
