Motivation: Program visualizations are widely used to support novice programmers, yet students often ignore or resist well-designed visual scaffolds. Research on multiple external representations (MERs) suggests cognitive design principles for coordinating views, but says little about what determines whether learners actually engage with the representations available to them.

Introductory programming (CS1) courses often struggle to support students' understanding of program execution. While visualizations can make execution processes explicit, their effectiveness depends on design and context, and empirical evidence for AI-generated visualizations remains limited. We propose Generated Animated Traces (GATs), AI-generated, analogy-based, narrated animations that coordinate source code, execution state, and conceptual analogies. We conduct a study at two institutions in CS1 courses (Python N=961; Java N=151) comparing GATs to textual explanations. We measure immediate learning performance and experience, end-of-course engagement and exam performance. Results show that GATs can yield selective benefits for immediate learning, but benefits are context-dependent and short-term. We observe that GATs' influence on performance is moderated by learner engagement profiles. This finding underscores the importance of personalized approaches.

As computing education becomes increasingly globalized, many students learn computer science through a second language. Prior work has documented cognitive and performance challenges faced by non-native English-speaking (NNES) students, yet less is known about how language background shapes their motivational experiences and intentions to persist. Drawing on Expectancy-Value Theory, we analyzed matched pre- and post-term survey data from 374 students (198 NNES, 176 NES) in a CS1 course at a large North American university. We measured programming self-efficacy, implicit theories of intelligence, need for cognition, sense of belonging, motivation and learning strategies, and intentions to major in computing. NNES students began the course believing intelligence is fixed and had lower self-efficacy on language-dependent tasks, gaps that persisted throughout the term. However, despite lower confidence, NNES students were more willing to choose challenging assignments and consistently used more strategic learning approaches. While NNES and native English-speaking (NES) students reported similar overall belonging, NNES students experienced greater belonging uncertainty, specifically when encountering difficulties, and were more likely to want to fade into the background within the CS community. These findings reveal language background as a persistent motivational cost in introductory computing and underscore the need for instructional designs that explicitly support belonging, self-efficacy, and adaptive strategy use for linguistically diverse learners.

Motivation: Database courses focus on SQL querying (DQL) while treating schema definition (DDL) and data manipulation (DML) as side topics, even though real-world database work begins with understanding schema design and data updates. This misalignment leaves students underprepared for authentic data management practice. Method: We integrated scaffolded DDL and DML exercises as a core concept in a third-year data course across three offerings (2023-2025). Students completed structured weekly tasks in an LMS that provides immediate feedback and unlimited attempts, encouraging low-stakes, iterative practice. We analyzed student interaction data (number of attempts and performance) to examine learning patterns across DDL/DML and DQL. We analyzed 9,071 total exercise submissions from 669 students, examining both the number of LMS exercise attempts and assignment performance across DDL/DML and DQL. Results: Students required fewer attempts on DDL/DML tasks than on traditional DQL tasks, indicating strong receptiveness when these topics were properly scaffolded. Early performance on schema-definition tasks was moderately correlated with later SQL performance, suggesting that schema competence supports subsequent query learning. Implications: We encourage database educators to teach schema design and data manipulation as core topics to strengthen students' conceptual foundations, as our results suggest these skills are learnable with scaffolding and may support subsequent query learning.

Motivation: Solid-state drives (SSDs) are now ubiquitous in computing systems, yet their internal data layout and operations remain largely invisible and difficult for students to conceptualize. Existing operating systems (OS) teaching materials provide minimal learning support for these abstract processes, which in turn limits student understanding. Method: We designed SSDVis, a web-based interactive SSD visualizer that enables students to simulate file operations and observe SSD internals through coordinated visualizations and step-by-step execution. We evaluated it in a third-year OS course by surveying students (N=154) on their usage and perceptions of SSDVis. Results: 95.4% of survey participants reported using the visualizer extensively, and the overwhelming majority reported improved understanding of SSD data layout, file operations, and garbage collection when using SSDVis. Students valued the interactive features for predicting and verifying behavior, including the step-by-step mode. While usage for understanding wear leveling was lower, this likely reflects the topic's inherent complexity to observe indirectly in elaborate scenarios, rather than usability issues. Implications: Our findings show that a pedagogically designed SSD visualizer has the potential to effectively support the learning of modern OS topics with complex hidden mechanisms.

Systematic Literature Reviews (SLRs) are fundamental to scientific progress, yet the process is hindered by a fragmented tool ecosystem that imposes a high cognitive load. This friction suppresses the iterative, exploratory nature of scholarly work. To investigate these challenges, we conducted an exploratory design study with 20 experienced researchers. This study identified key friction points: 1) the high cognitive load of managing iterative query refinement across multiple databases, 2) the overwhelming scale and pace of publication of modern literature, and 3) the tension between automation and scholarly agency.

This pilot study investigated students' perceptions of visual progress bar and on-demand hints in a CS1 course. Students valued both feedback systems, with more confident students preferring on-demand hints for direct problem-solving support. Progress bars were consistently perceived as beneficial across varying confidence levels.

Machine learning (ML) has become increasingly important for students, yet university-level ML courses are often perceived as challenging and time-intensive. This study explores the perceived challenges and motivations of students in a university ML course to inform curricular and teaching strategies. Through 5 surveys conducted in two instances of a 12-week introductory ML course, we examined students' engagement with both theoretical and practical aspects of ML. Results indicate that while students initially express strong interest in applying ML concepts, their reported interests can shift toward theoretical foundations. Challenges in both theory and practice are reported, including difficulties in mathematical notation and vectorization of gradient components, as well as model implementation. Students also discuss the time commitment required in a course with both theoretical and practical content. We recommend aligning course content with student motivations, providing targeted support for mathematical notation and vectorization, and balancing theoretical depth with practical application.

Self-explanation promotes active learning by having students articulate their conceptual understanding in their own words. This study investigates whether the timing of self-explanations (before vs. after solving an exercise) relates to performance in a flipped, second-year computer organization course. Although students who self-explained before the exercises achieved higher course marks, the difference was not significant. Still, these findings suggest that early self-explanation may better prepare students for problem-solving when learning new concepts.

Self-explanation deepens understanding by giving learners an opportunity to reflect on what they are learning in a structured way. However, many students struggle to engage in it effectively. We investigate whether large language models (LLMs) can scaffold self-explanations in a flipped computer organization course. In an A/B test, one group used a fixed prompt to compare their explanations with an expert's, while another engaged in an interactive dialogue with an LLM to identify gaps. Although the overall quality of the explanation did not differ significantly between conditions, some students (non-native English speakers and women) reported greater comfort and perceived value when using the LLM.

Creating a supportive community in introductory programming courses is vital to student success, yet forums meant to facilitate this can cause stress due to social comparison. According to social identity theory, students are more likely to engage and feel a sense of belonging when they perceive connections with their peers. This study investigates whether peer-modeled posts that simulate students exhibiting desirable engagement behavior can reduce feelings of isolation and foster social connection among students. We introduced curated posts modeling expected student behavior -- covering content, providing emotional support, and offering study tips -- into Q&A forums for two introductory computing courses. These posts were inserted using different student accounts. Surveys and forum data were analyzed to measure the impact on students' feelings of isolation. Students responded positively to the seeded posts, reporting a significant reduction in feelings of isolation. Notably, women reported feeling less isolated after seeing the posts more than men, and many students reported feeling relieved that other students had the same worries and concerns as them. Seeding peer-modeled posts can significantly reduce student isolation and foster a greater sense of belonging in competitive academic contexts. However, future work may explore alternative delivery mechanisms, such as instructor posts framed as ''questions from last year,'' to determine if they can achieve similar effects.

This research evaluates voice-based self-explanations as a pedagogical tool in preparation for lectures, assesses user preferences between voice and text, and derives design insights. We report two studies: Study 1, a quasi-experimental field study, with 247 participants divided into voice-based (N = 83), text-based (N = 81), and choice (N = 83) conditions. Study 2 uses semi-structured interviews (N = 16) to explore perceptions of the interaction paradigms in-depth. Results from the first study revealed a general preference for text, though voice users produced longer responses and more topic-related keywords. Over time, the preference for voice increased among students, from 10% to 46%, when given a choice. Study 2 suggested that factors like social presence contribute to hesitance toward voice-based explanations, with a cognitive load, self-confidence, and performance anxiety also influencing medium preferences. Our findings highlight design recommendations and demonstrate the potential of voice-based self-explanations in educational settings, indicating that mixed interfaces might better meet diverse needs.

Motivation: Q&A forums are a critical resource for supporting students in large educational environments, yet students often perceive these forums as stressful and report discomfort in participating visibly, especially in classes that are large and have students with varying levels of prior programming experience (PE). Method: We divided students in a CS1 Q&A forum into smaller, homogenous groups based on their PE. We use a mixed-methods approach to compare data from this experience to data from a setting where all students shared a single, large Q&A forum (a “mixed” setting). We quantitatively analyze measures of student engagement and use an open-ended qualitative approach to examine responses about student experience on the forums. This approach helps us identify the motivation behind student decisions to participate in visible or non-visible ways and to evaluate their alignment with theoretical frameworks. Results: In the mixed setting, students frequently use anonymity, with students without PE using anonymity more than students with PE and women using anonymity more than men. In contrast, in the homogenous groups, novices used anonymity less than novices in the mixed setting, while the students in higher-experience groups tended to use it more. We also observe a reduced anonymity usage among women in the homogenous experience groups, suggesting that PE plays a critical role in the observed gender disparities in forum participation. The qualitative analysis provides additional evidence that social status issues and confidence may explain these behavioral patterns. Conclusion: This study highlights the potential benefits and consequences of grouping students by experience. Homogenous PE groups foster increased student comfort and engagement within the Q&A forum for students with less experience, but students with more experience are exposed to more perceived status threats. We discuss how these results align with the theories we used to design the homogenous group setting. This exploration contributes to a deeper understanding of the underlying dynamics shaping student behavior in online learning communities. Educators and platform designers can use these lessons to more effectively create inclusive environments that accommodate diverse student needs and preferences.

Faculty and industry practitioners recognize written communication to be important in computer science, but it can be challenging to convince students of the same. As student perceptions are molded early in a program of study, we focus on early-year CS students to understand their perceptions towards the importance of writing in CS, with the goal of framing discipline-specific writing pedagogy. We qualitatively analyze responses from first and second-year CS students in a survey about the role of writing in their field. The responses reveal that a majority view writing as an indispensable skill. Specifically, students recognize it as a fundamental skill, applicable across diverse contexts, and uniquely relevant in CS compared to other fields. We identified 4 perceptions that they hold which are helpful to their development as writers: that writing is a useful fundamental skill, which is useful for achieving various goals in a variety of contexts, and that writing in CS is different than in other fields. However, 20% of responses include reasons why writing is not important in CS, and we identify 4 perceptions harmful to students' development as writers: that writing skills can be avoided, are defined narrowly, do not need to be developed beyond a baseline, and come at the cost of computing skills. We believe that there is an opportunity to align discipline-specific writing instruction with these useful and harmful perceptions.

In computing courses, instructor involvement and social comfort are vital for resilience and belonging. We examine engagement with instructor emails aimed at strengthening the connection with students. We sent weekly emails from instructors to first- and upper-year computing students. These emails included reminders for the assignments due each week. Half of the students received reminders embedded in an informal message that contained approachable wording and relevant current course events, while the rest received a list of precise deadlines. This text had no emotional engagement from the instructor. We collected and analyzed email access and link click rates, along with student survey responses about email preferences and engagement. We found that first-year students had lower email access and link click rates than upper-year students. While we did not find differences in first-year engagement based on the type of email, upper-year students appeared to be more engaged when receiving the intentionally informal version of the email. Understanding the message preferences of computing students can enhance instructor messaging and improve engagement. Strategies should be explored to boost first-year student engagement, while the higher engagement among upper-year students underscores the importance of instructor support in advanced courses.

Asking for help (help-seeking) is a recognized and effective problem-solving strategy. This study investigates students' interaction with on-demand hints (automated hints requested by students) and assesses their impact on learning progress. We conducted an A/B experiment in a third-year computer science database course, offering hints for selected SQL problems with different hint designs. We collected data on students' code submissions, grades, and hint requests, and we administered a survey to gather feedback and gauge student perception of the hints. Many students accessed hints immediately without attempting the problem first, often requesting multiple hints in quick succession. While students perceived the hints to be valuable, we did not detect an impact on student problem-solving. These insights could inform future studies on the possible impact of students' attitudes toward hints, and how different types of hints might impact uptake and perception of hints.

This study explores links between attributes of computing students, such as prior programming experience (PE) and gender, with expectations for success and the perception of challenges. Using Expectancy-Value Theory (EVT), we investigate their major intentions and the impact of these factors post-CS1. Data was gathered using surveys at the beginning and end of an introductory programming course, focusing on demographics, expectations of success, and perceptions of challenges. Application status for the computing major was also recorded. Our results revealed that men and students with PE generally perceived greater potential for success and reported facing fewer challenges. In contrast, women and students without PE more often indicated concerns about intellectual ability and perceived challenges less positively. Notably, while gender appears in the preceding results, an intersectional analysis indicates that PE is the central factor. PE is also linked to persistence in the field of computing. Our results further highlight the importance of providing students with opportunities to develop experience, as it can help shape their expectations, perceived challenges, and retention in computing.

Generating self-explanations has been identified as a successful strategy in helping learners engage with course content and organize what they learn in a structured format. While typing an explanation may allow more structure and formality, explaining by voice can be more natural and help free cognitive resources to focus on learning goals and understanding concepts. As we investigated the effects and students' perceptions of using voice or text to self-explain new course concepts, we failed to find a tool that would meet our needs. We present our work in designing and developing VoiceEx, a submission courseware that allows text and voice input to collect data in both mediums. VoiceEx was created to support a self-explanations intervention for computer science students; however, given its features and the advantages of being able to collect spoken responses, it can be used in a variety of environments. Future refinement of this tool includes artificial intelligence features to better guide students' submissions.

In this poster, we present a pilot study investigating the impact of the medium used for self-explanation on students' performance outcomes in a databases course. We did not see notable differences in student performance based on the medium they used for self-explanation. We also note that while most students prefer using text to submit self-explanations, their preferences may differ when they use voice.

At ITiCSE 2021, Working Group 3 examined the evidence for teaching practices that broaden participation for women in computing, based on the National Center for Women & Information Technology (NCWIT) Engagement Practices framework. One of the report's recommendations was "Make connections from computing to your students' lives and interests (Make it Matter) but don't assume you know what those interests are; find out! " The goal of this 2023 working group is to find out what interests women students by bringing together data from our institutions on undergraduate module enrollment, seeing how they differ for women and men, and what drives those choices. We will code published module content based on ACM curriculum guidelines and combine these data to build a hierarchical statistical model of factors affecting student choice. This model should be able to tell us how interesting or valuable different topics are to women, and to what extent topic affects choice of module - as opposed to other factors such as the instructor, the timetable, or the mode of assessment. Equipped with this knowledge we can advise departments how to focus curriculum development on areas that are of value to women, and hence work towards making the discipline more inclusive.

Q&A forums are widely used in large classes to provide scalable support. In addition to offering students a space to ask questions, these forums aim to create a community and promote engagement. Prior literature suggests that the way students participate in Q&A forums varies and that most students do not actively post questions or engage in discussions. Students may display different participation behaviours depending on their comfort levels in the class. This paper investigates students' use of a Q&A forum in a CS1 course. We also analyze student opinions about the forum to explain the observed behaviour, focusing on students' lack of visible participation (lurking, anonymity, private posting). We analyzed forum data collected in a CS1 course across two consecutive years and invited students to complete a survey about perspectives on their forum usage. Despite a small cohort of highly engaged students, we confirmed that most students do not actively read or post on the forum. We discuss students' reasons for the low level of engagement and barriers to participating visibly. Common reasons include fearing a lack of knowledge and repercussions from being visible to the student community.

Previous work has reported on the advantageous effects of prior experience in CS1, but it remains unclear whether these effects fade over a sequence of introductory programming courses. Furthermore, while student perceptions suggest that prior experience remains important, studies have reported that a student's expectation of their performance is a more accurate predictor of outcome. We aim to confirm if prior experience (formal or informal) provides short-term and long-term advantages in computing courses or if the advantage fades. Furthermore, we explore whether the expectation of performance is a more accurate predictor of student success than informal and formal prior experience. To explore these questions, we deployed surveys in a CS1 course to gauge students' level of prior experience in programming, prediction of final exam grades, and self-efficacy to succeed in university. Grades from CS1 and CS2 were also collected. We observed a persistent (1-letter grade) gap between the performance of students with no prior experience and those with any experience, but we did not observe a noteworthy gap when comparing student performance based on formal or informal experience. We also observed differences in self-efficacy and retention rates between different levels of prior experience. Lastly, we confirm that success in CS1 can be better reflected and predicted by some controllable factors, such as students' perceptions of ability.

Many students are first exposed to computing in a programming course such as CS1. This course affects their understanding of computing and may affect their intention to major in the program. We investigate the intention to major in computing in relation to demographic factors and factors related to academic success. We deployed surveys at the beginning and end of a CS1 course to gauge students' level of prior experience in programming, elicit demographic factors such as gender and parental education level, and identify their intention to major in computing. Grades from CS1 and CS2 were also collected. Our results suggest that most students do not change their intention to major in computing after taking CS1. Students who were more likely to intend to major in programming at the beginning of the course were those with prior experience, those who identified as men, or students who had a parent with a bachelor's or post-grad degree. We also find that students' grades correlate to their change in program intention. This reinforces the need to change perceptions about computing early, prior to CS1.

With the widespread usage of mobile devices, users can now choose to provide input through voice or text. As researchers frequently ask students open-ended questions, we want to explore a natural mode to obtain better feedback in surveys. This study details a preliminary study demonstrating the importance of allowing students to choose between voice or text input to respond to surveys. A survey with several open-ended questions was deployed in a CS1 course. Correlations between the gender of the respondent and their method of responding were evaluated. We found that voice responses tended to be longer and preferred more by females relative to male students.
