Attendance and Missing Class: Attendance in ECS 101 is MANDATORY beginning on January 22nd, 2026. First, my lecture slides are text-poor, which means that without hearing what I say about each slide, you will NOT be able to reconstruct this information purely from the slide. Second, the review quizzes are not by themselves sufficiently comprehensive to let you do well on exams, despite what you might have heard.
Beginning January 22nd, 2026 (the day after Drop/Add), there will be the possibility that I will give an unannounced, pop-quiz during class, for a total of 6 pop-quizzes. You may miss ONE of these without penalty. After that, for every pop-quiz you miss, I will take off 0.7% of your attendance grade (up to a total of 3.5%).
IF you think you must miss lecture due to emergency, family, health, or other valid reasons, you MUST fill out a short-term illness form. An excused absence does not count towards the one “free” absence you can have. Athletes MUST provide a list of dates they will be absent during the semester (as anticipated or develops). Missing class, even excused (but see below), does not entitle you to multimedia or audio lecture recordings of the class. It is your responsibility to get good notes from someone who was there. We are unable to go through entire lectures that you missed during office hours. We can certainly answer specific questions.
If you are excused for more than three or more consecutive lectures PLEASE contact the instructor to discuss receiving additional help. Duke University has established procedures to deal with long-term absences due to illness, as well as family emergencies. Information can be found HERE.
