DESCRIPTION:Abstract: Exams are an important tool for summative assessment\
 , whose utility has only grown with the advent of large language models (LL
 Ms) like ChatGPT\, because they can be implemented in a trustworthy manner.
   But exams are generally not well liked by either students or faculty.  St
 udents find them stressful. For faculty (and their course staff)\, they rep
 resent a large adminstrative burden to write\, proctor\, and grade.  This l
 arge burden means they are done infrequently in many classes\, but this inf
 requent testing encourages cramming and leads to high test anxiety.\n\nIn t
 his talk\, I'll share (1) research on the benefits of frequent testing and 
 "second-chance testing" (optional exam re-takes) on increased student learn
 ing and decreased test anxiety\, (2) research on patterns of cheating on un
 proctored online assessments\, and (3) how we've reduced the instructor wor
 kload at Illinois to implement frequent testing through our Computer-Based 
 Testing Facility (CBTF).  The CBTF is a collection of proctored computer la
 bs that\, in conjunction with the PrairieLearn open-source question-asking 
 platform\, enable our faculty to run sophisticated exams with almost no rec
 urring effort even in the largest classrooms.  For example\, our CS 1 cours
 e for majors (run by a single faculty member) ran weekly exams for 1\,150 s
 tudents.  Key enabling ideas for the CBTF include: (1) sophisticated auto-g
 rading questions\, (2) question generators\, (3) asynchronous exams\, and (
 4) dedicated testing space and proctors.  The CBTF has been running for ove
 r 10 years and proctored over 100\,000 exams last semester.  \n\nBio: Craig
  Zilles is a Professor and Severns Faculty Scholar in the Siebel School of 
 Computer and Data Science at the University of Illinois at Urbana-Champaign
 . His current research focuses on applying computing and data analytics to 
 education\, including the development of the Computer-Based Testing Facilit
 y (CBTF).  Previously\, his research focused on the interaction between com
 pilers and computer architecture\, and he developed the first algorithm tha
 t allowed rendering arbitrary three-dimensional polygonal shapes for haptic
  interfaces (force-feedback human-computer interfaces).  He received the IE
 EE Education Society's 2010 Mac Van Valkenburg Early Career Teaching Award 
 and an NSF CAREER award.  At Illinois\, he has received a wide range of tea
 ching awards\, including a 2018 Campus Award for Excellence in Undergraduat
 e Teaching\, a 2013 Illinois Student Senate Teaching Excellence Award\, and
  the College of Engineering's Rose Award (2007) and Everitt Award (2008) fo
 r Teaching Excellence.  He holds 5 patents and his research has been recogn
 ized by a best paper awards from ASPLOS in 2010 and 2013 and by selection f
 or inclusion in the IEEE Micro Top Picks from the 2008 Computer Architectur
 e Conferences.\n\nPlease join us in DLC 1B70 or on Zoom for this talk!
