Museum exhibits often rely on visualizations or graphics to communicate scientific data to the general public. These visual representations render the benefits of these exhibits inaccessible to blind and low vision (BLV) learners. While both tactile and auditory representations of data can serve as accessible alternatives to visualizations for BLV learners, there is little work exploring how the unique affordances and drawbacks of these modalities affect learning about data in informal learning environments (ILEs). Our work seeks to further this understanding through the design and evaluation of an accessible and interactive display for learning about ocean data. We prototyped three versions of our display, each with a different modality for representing habitat data (sound, texture, sound and texture). By prototyping multiple versions, we investigate how auditory and tactile feedback can be leveraged to support informal learning about scientific data.

Artificial intelligence (AI) is ubiquitous in K-12 youths' everyday lives. However, it has become increasingly well-documented that AI can cause harm by reflecting and amplifying societal biases. While many youth are not currently empowered to engage in broader responsible AI discourse and processes, there is great potential. Foundational to engaging in critical conversations is ability to critique AI. We present the RAD framework, designed to scaffold critique of AI in three steps: Recognize (harms of AI), Analyze (societal aspects of AI harms), and Deliberate (what more responsible AI could be). We ran a workshop study with racially diverse middle school girls (N = 21) to investigate its effectiveness. We found that through being scaffolded with the framework, the youth could articulate biases that they saw in an AI scenario and consider how biases may impact different stakeholders. They then could contemplate how different stakeholders had varying amounts of power in the AI scenario and what that meant in terms of creating more responsible AI systems and processes. After participating in the study, the youth felt more strongly about voicing their opinions about AI with others. The RAD framework and activities work toward emboldening youths' engagement in critical discourse about AI.

Open-source software projects have become an integral part of our daily life, supporting virtually every software we use today. Since open-source software forms the digital infrastructure, maintaining them is of utmost importance. We present Climate Coach, a dashboard that helps open-source project maintainers monitor the health of their community in terms of team climate and inclusion. Through a literature review and an exploratory survey (N=18), we identified important signals that can reflect a project’s health, and display them on a dashboard. We evaluated and refined our dashboard through two rounds of think-aloud studies (N=19). We then conducted a two-week longitudinal diary study (N=10) to test the usefulness of our dashboard. We found that displaying signals that are related to a project’s inclusion help improve maintainers’ management strategies.
