Proceedings of the Working Group Reports on Innovation and Technology in Computer Science Education

In these proceedings, we present reports from the Working Groups that convened at the 24th Annual Conference on Innovation and Technology in Computer Science Education (ITiCSE), held at the University of Aberdeen, Scotland, UK from July 15 to July 17, 2019. The concept of Working Groups has been a unique feature since the start of the ITiCSE conference series, with CompEd adopting the Working Group practice in 2019. A Working Group comprises of typically 5 to 10 researchers who work together on a project related to computing education. Working Groups provide a wonderful opportunity to work intensively on a topic of interest with an international group of computing education researchers. Working groups begin work electronically before the ITiCSE conference. They convene for face-to-face work three days before the conference (usually on the Friday evening), work together during the two days before the conference starts, and continue working throughout the three days of the conference. At the end of the conference, each group submits a draft report and a few weeks after the conference they submit a final report for review. If the report is accepted, the groups revise it based on the reviewers' comments and suggestions for the camera-ready version that is going to be published as a dedicated Working Group proceedings volume in the ACM Digital Library. This unique experience is one that, in our opinion, each Computer Science Educator should strive to participate in at least once. In 2019, 16 proposals for Working Groups were received and ten Working Groups were selected by the Working Group chairs to convene at ITiCSE 2019. Participants presented their results to conference attendees at one of two special working group presentation sessions. Their final reports were double blind reviewed by at least three selected expert reviewers, and we are glad that nine reports were selected for publication in these proceedings for the ACM Digital Library.
