Acoustic scattering is strongly influenced by boundary geometry of objects over which sound scatters. The present work proposes a method to infer object geometry from scattering features by training convolutional neural networks. The training data is generated from a fast numerical solver developed on CUDA. The complete set of simulations is sampled to generate multiple datasets containing different amounts of channels and diverse image resolutions. The robustness of our approach in response to data degradation is evaluated by comparing the performance of networks trained using the datasets with varying levels of data degradation. The present work has found that the predictions made from our models match ground truth with high accuracy. In addition, accuracy does not degrade when fewer data channels or lower resolutions are used.

The goal of the session is to help attendees who are committed to diversity and inclusion learn to talk about different dimensions of identity (e.g., race, class, gender, sex, sexuality, etc.). The landscape of terms is always changing and we want SIGCSE attendees to feel more comfortable using current language to talk about issues related to diversity and inclusion. This special session will include eight short videos, individual reflection, and a Q&A with presenters. This is an expansion of a special session held at the NCWIT Summit in 2019; it was well received and we hope to offer it to the larger SIGCSE audience. The format also lends itself to attendees sharing the videos and discussions with their colleagues after SIGCSE, which are available at http://ncwit.org/intersectionality-videos

Navigating the intersection of both race and gender can be difficult for Black women in academia, especially when they lack representation, and proper support, which forces many to "learn on the fly." This panel convenes Black women in diverse faculty positions to discuss pursuing and persisting in academic careers, including career path considerations, identifying and mitigating challenges, mentorship and networking, balancing expectations with authenticity, and making institution and/or career changes.

Many SIGCSE attendees bring what they learn at SIGCSE back to their colleagues. In our well attended Special Sessions at SIGCSE in 2018 and 2019, attendees learned to respond to bias, which might be more difficult to bring back to their colleagues. This workshop will prepare attendees to lead interactive-sessions about responding to bias at their institution or at other conferences. The workshop will begin by modeling an interactive-session with updated materials from SIGCSE 2019. The workshop attendees will then explore facilitation strategies, ways of managing difficult conversations, and all attendee concerns. All attendees will receive printed copies of the game (csteachingtips.org/cards) to use at their institution or to local conferences.

Many SIGCSE attendees are committed to inclusive teaching practices and creating an inclusive culture within their classrooms; yet, advocating for and sustaining these initiatives may require having difficult conversations with our colleagues and students. Understandably, many faculty are unsure about how to talk about sensitive topics such as race and gender with their colleagues and students. Research suggests that practicing some of these difficult conversations is essential to achieve the goals of inclusive teaching and culture. In our well attended session at SIGCSE in 2018, attendees learned strategies for responding to bias in academic settings. This was facilitated by playing two rounds of a research-based game developed by the NSF project CSTeachingTips.org (#1339404). This session will extend the work begun last year by helping attendees to replicate this activity with their colleagues. In this special session, attendees will first play the game to practice those strategies in small groups and will then receive facilitation tips and guidance for conducting this activity on their own. All attendees will receive a printed copy of the game and a link to download and print more copies.

SIGCSE is packed with teaching insights and inspiration. However, we get these insights and inspiration from hearing our colleagues talk about their teaching. Why not just watch them teach? This session does exactly that. Each of six exceptional educators will be given ten minutes to teach the audience something. After this, the moderator will draw the attention of the audience to particular pedagogical moves that the instruction included. Attendees can see a new approach to introducing a topic or a new pedagogical move. No matter what, we expect attendees will be taking ideas from this session directly back to their teaching! The format is based upon a practice in chemistry of sharing "Five Slides About," which introduce a topic in a novel or concise way (https://www.ionicviper.org/types/five_slides_about). Resources from each of the presenters will be shared on the website CSTeachingTips.org.

Most SIGCSE attendees probably use active learning throughout their teaching, but we rarely see active learning at SIGCSE - let's try it! In this interactive session, attendees will learn strategies for responding to bias in academic settings. Attendees will then practice those strategies in small groups. This will be facilitated by playing two rounds of a research-based game learning approach developed by the NSF project CSTeachingTips.org (#1339404), which has been tested in group of 200 teaching assistants. This is the fifth iteration of the game-learning approach and all attendees will receive a printed copy of the game and a link to download and print more copies.
