Online professional development (PD) can reach teachers from widespread areas. Here, we describe PD activities that are part of a project focused on integrated science, technology, engineering, and mathematics (iSTEM) teaching self-efficacy and effectiveness among earlycareer elementary teachers. Toward our objective of building a community of elementary teachers focused on improving their iSTEM teaching, we are conducting online PD institutes over four summers. These PD institutes are designed using Desimone’s five critical features of effective PD: content focus, active learning, coherence, duration, and collective participation. Our institutes engage teachers in an initial synchronous online session, which is followed by independent work time to put their learning into practice. It concludes with a final synchronous online session where teachers share their asynchronous work, receive feedback, and identify the next steps in enacting their learning in the classroom. Below we describe the first year’s PD activities. 

Engineering programs have long struggled with balancing curricula that are rigorous enough to prepare graduates to be capable practitioners and educational experiences that are engaging enough to retain undergraduate students. Data show a little more than half of students who start in a program leave after the first or second year, and that many of those students came to dislike engineering or lost interest in the profession. These findings suggest a mismatch between what incoming students think engineering practice is and what message they receive during their first two years of a program. This work will aim to understand how contextualization of what it means to practice engineering can improve the intentions of students, particularly those identifying as underrepresented minorities and women, to persist in a discipline that historically struggles to retain them. With this understanding, changes can be made to undergraduate engineering education to better retain students. In addition, this work will contribute new knowledge about students’ understanding of what it means to practice engineering and how that understanding changes with exposure to different types of contextualization (e.g., historical or technical). It will also contribute new knowledge about how undergraduate students associate engineering science and judgement with engineering practice, particularly with respect to how these facets of engineering practice are directly in service to design. Engineering science courses that occupy the middle two years of a program most often utilize traditional lecture-based pedagogy and simplified close-ended textbook problems, which do not typically allow students to engage in the kind of decision-making that is essential to developing engineering judgement. This work proposes a teaching pedagogy intended to provide students with context for how engineering science concepts are implemented in authentic engineering practice and how engineering judgement is essential in that implementation. Moreover, this work will aim to employ another teaching pedagogy to provide a more holistic contextualization of engineering practice by introducing students to the history of the profession. This pedagogy was implemented during the Fall 2023 semester in a required seminar course for mechanical engineering sophomores at [name of university]. This work will advance the field of engineering education research by studying how students’ perceptions of engineering practice develop as they progress through a program, and how these educational activities can shape that progress and/or reframe their beliefs about their education and training. Semi-structured interviews will reveal how students’ perceptions of engineering practice change longitudinally and whether the aforementioned educational activities influence that trajectory. In addition, a larger group of students will be invited to participate in surveys, which will enable drawing inferences from a broader sample about intention to persist as well as baseline levels of familiarity with engineering in general. 

The double star system WDS 22267+4433 ES 1346 AC was observed using the Las Cumbres Global Telescope Network (LCOGT) 0.4 meter telescope on October 19th, 2023. Upon observation, the position angle was 359.97° and the separation was 7.997″. This data was compared to historical data acquired from the Washington Double Star Catalog, the US Naval Observatory, and the Gaia Database. Because Gaia DR3 does not have parallax and proper motion values for the primary or secondary stars of this system, a comparison to the C component could not be made. 

With the decreasing cost of consumer display technologies making it easier for universities to have larger displays in classrooms, and the ubiquitous use of online tools such as collaborative whiteboards for remote learning during the COVID-19 pandemic, combining the two can be useful in higher education. This is especially true in visually intensive classes, such as data visualization courses, that can benefit from additional "space to teach," coined after the "space to think" sense-making idiom. In this paper, we reflect on our approach to using SAGE3, a collaborative whiteboard with advanced features, in higher education to teach visually intensive classes, provide examples of activities from our own visually-intensive courses, and present student feedback. We gather our observations into usage patterns for using content-rich canvases in education. 

While proving, and more broadly conceived “reasoning and sense-making,” have received a great deal of attention in mathematics education research over the past three decades, recently scholars have argued for the importance of justification as a learning and teaching practice. As teachers work toward realizing goals for more equitable classroom environments, little is known about whether teachers’ conceptions about mathematical practices, such as justification, reflect an understanding of how students’ engagement in those practices can support more than just mathematical achievement. In this paper, we present findings from our analysis of interviews with 10 secondary mathematics teachers engaged in participatory action research to explore connections, and potential disconnections, between teachers’ conceptions of justification and their visions for equitable instruction. 

September 2023 marks the 50th anniversary of the Electronic Visualization Laboratory (EVL) at University of Illinois Chicago (UIC). EVL's introduction of the CAVE Automatic Virtual Environment in 1992, the first widely replicated, projection-based, walk-in, virtual-reality (VR) system in the world, put EVL at the forefront of collaborative, immersive data exploration and analytics. However, the journey did not begin then. Since its founding in 1973, EVL has been developing tools and techniques for real-time, interactive visualizations—pillars of VR. But EVL's culture is also relevant to its successes, as it has always been an interdisciplinary lab that fosters teamwork, where each person's expertise contributes to the development of the necessary tools, hardware, system software, applications, and human interface models to solve problems. Over the years, as multidisciplinary collaborations evolved and advanced scientific instruments and data resources were distributed globally, the need to access and share data and visualizations while working with colleagues, local and remote, synchronous and asynchronous, also became important fields of study. This paper is a retrospective of EVL's past 50 years that surveys the many networked, immersive, collaborative visualization and VR systems and applications it developed and deployed, as well as lessons learned and future plans. 

SAGE3 is software to augment the cyberinfrastructure-enhanced research and education enterprise by supporting data-intensive collaboration across a wide range of display devices from high-resolution display walls to laptops. This paper provides insight into SAGE3’s implementation, which significantly improves on prior generations of SAGE by leveraging emerging advancements in Web technologies and Artificial Intelligence. We also provide an overview of new usage patterns that we observed with SAGE3.
