theodp writes: After a flood of cheating cases roiled Harvard's Computer Science 50: "Introduction to Computer Science I" last year, Dean of Undergraduate Education Jay Harris implored students in the course not to cheat on assignments at an orientation session Wednesday night. Course head David Malan, the Harvard Crimson reports, spent the last five minutes of the orientation session fielding questions from students confused about the course's collaboration policy and whether or not CS50 enrollees are allowed to use code found online. He told them never to Google solutions, and never to borrow a friend's work. Last week, CS50 students were informed via a CS50 FAQ that they are also now "encouraged" to physically attend the course's taped weekly lectures. In an essay last year, Prof. Malan had questioned the value of saying everyone should attend every lecture. Attendance is now also expected at every discussion section until the first mid-semester exam. In case you're curious, the estimated sticker price for attending Harvard College during the 2017-2018 school year is $69,600-$73,600 (health insurance sold separately).
