HCI engages with data science through many topics and themes. Researchers have addressed biased dataset problems, arguing that bad data can cause innocent software to produce bad outcomes. But what if our software is not so innocent? What if the human decisions that shape our data-processing software, inadvertently contribute their own sources of bias? And what if our data-work technology causes us to forget those decisions and operations? Based in feminisms and critical computing, we analyze forgetting practices in data work practices. We describe diverse beneficial and harmful motivations for forgetting. We contribute: (1) a taxonomy of data silences in data work, which we use to analyze how data workers forget, erase, and unknow aspects of data; (2) a detailed analysis of forgetting practices in machine learning; and (3) an analytic vocabulary for future work in remembering, forgetting, and erasing in HCI and the data sciences.

Who is an activist? With the advent of activism-related scholarship in HCI and CSCW, the current challenge involves thinking about what activism is, who an activist is, and the opportunities and limitations of activism. Recently, researchers in academia and industry, such as Timnit Gebru, demonstrate a commitment to stay activated for the structural changes we need, for example, diverse and inclusive scholarship, to address overlapping problems, e.g., sexism, racism, and tokenism. Additionally, there is a continuing dominance of Western, formally educated, industrialized, rich and democratic (WEIRD) perspectives. Countering this requires collective efforts in citational justice and decolonial computing, among others. But such complex issues do not yet cover the inner conflicts that we face, such as mental health struggles while dismantling the prejudices stemming from the ivory tower, locating our privileges as academics while traversing less privileged locales of research sites, or the dilemmas on whether we are doing enough to fulfill our responsibilities to the people who have trusted us enough to work with us in the face of ”publish or perish” culture. This workshop explores what activism means within the CSCW community and how we can remain activated while harboring doubts and hopes in calling ourselves ”activists”.

In recent years HCI and CSCW work has increasingly begun to address complex social problems and issues of social justice worldwide. Such activist-leaning work is not without problems. Through the experiences and reflections of an activist becoming academic and an academic becoming an activist, we outline these difficulties such as (1) the risk of perpetuating violence, oppression and exploitation when working with marginalised communities, (2) the reception of activist-academic work within our academic communities, and (3) problems of social justice that exist within our academic communities. Building on our own experiences, practices and existing literature from a variety of disciplines we advocate for the possibility of an activist-academic practice, outline possible ways forward and formulate questions we need to answer for HCI to contribute to a more just world.

On the International Day to End Violence Against Sex Workers (IDEVASW), sex worker rights advocates and support services commemorate lives lost due to violence. In this paper we describe and reflect on a Feminist Participatory Action Research project that supported the activities of IDEVASW over two years in North East England. Working alongside a charity that provides services to women who are sex workers or have experienced sexual exploitation, we co-organised the first activist march on the day. As researchers and service providers, we present detailed reflections on the use of digital technologies during the public activist march, a private service for commemoration, and the development of a semi-public archive to collect experiences of the day. We develop three implications for the design of digital technologies for activism and the commemoration of lost lives: as catalysts for reflection and opportunities to layer experience.

Feminist HCI has made a profound impact on perceptions of women's health, emancipation through design, as well as gender identity, inclusion, and diversity. However, there is a distinct lack of connection between these disparate but inherently connected research spaces. This SIG meeting aims to bring scholars together to discuss emerging and evolving issues of feminist research, and finding ways of using feminist theory and practice as a tool in future HCI research. Ultimately, the SIG will facilitate the engagement of a community of feminist HCI researchers, designers, and practitioners. It brings together those who may feel isolated in their respective research groups or universities to create a platform for feminist thought within SIGCHI and facilitate collaboration to proactively move towards the mainstreaming of feminism in HCI.

We aim to bring together a number of researchers to share their stories and discuss opportunities for improvement in research practice with Third Sector Organisations such as charities, NGOs, and other not-for-profit organisations. Through these discussions, we will develop a framework for good practice, providing guidance on conducting research with these organisations, their staff, and their beneficiaries through ethical methodologies and methods. We will do this by discussing three ways in which working with TSOs impact the work we do: (1) the ways in which this kind of work impacts the third sector; (2) the ways in which it impacts the research itself; and (3) the ways in which it impacts us as researchers and people.

DIY-making can be an expensive pastime if makers are relying on ready-made toolkits, specialised materials and off-shelf components. Many prefabricated commercial kits seek to lower the learning barrier of making and to help beginners to successfully take their first steps in engineering. However, as soon as the novices become a little more advanced, these toolkits often do not fit the specific requirements of personal maker projects anymore. We introduce the idea of a Schnittmuster (or a meta-toolkit) as a novel approach to toolkit design that seeks to address these creativity-limiting factors as well as practical entrance hurdles. To demonstrate the adaptive power of the Schnittmuster concept, we discuss an exemplar in the context of capacitive touch sensing (FlexE-Touch). Implemented under the constraints of materials, user skill sets and making environments, we illustrate how the Schnittmuster facilitated four cheap and flexible toolkit instantiations for crafting custom touch sensor electrodes.

Non-homeless youths outperform their homeless peers in school even if they live in extreme poverty. This disadvantage can have long-term consequences for engagement with and navigation of wider society. In this paper we examine how differences in achievement could be tackled outside of school through the re-envisioning of ecologies of digital education. Through interviews, design workshops, and a street visit with a total of 20 homeless young adults during a three-week engagement with a centre for people of low social stability in Bucharest, Romania, we examine the perceptions of education among street involved youth or adults. We identify the core values, aspirations, opportunities and barriers for education among these people, including survival, friendship, learning networks, and curiosity. These findings resulted in five implications for design: learning "happens", learning "works", designing for distanced learning, designing for the social politics of learning, and designing artefacts of everyday learning. These show the importance and necessity of educational reform in the field of HCI.
