What does the phrase “diverse students” mean? An exploration of CS teachers’ ideas of race, culture, and community in their classrooms

ABSTRACT Background and Context Recent research suggests that there is work to be done in overcoming color-evasive ideologies in Computer Science (CS) education. In particular, we have limited insight into how to support white teachers in using Culturally Responsive Computing (CRC) approaches. This paper addresses this gap in the literature by analyzing interviews with white high school CS teachers through the lens of hegemonic whiteness. Objective We ask two questions 1) What are the gaps between these teachers’ views on culture, community, and responsiveness, and how CRC envisions the interplay of these three elements? 2) How can we use teachers’ understandings to reconceptualize presenting CRC to them in a manner that may best benefit their students? Method We use semi-structured interviews of nine teachers until data saturation. We use in-vivo and values coding in the first round and code-weaving in the second round to come up with emergent themes. Findings Our findings show that these teachers did one or more of the following: 1) had dynamic but content-agnostic views about culture in the classroom; 2) focused on community connections with academia, industry, and/or parents; 3) framed the challenges of implementing CRC through a deficit lens; and 4) valued students’ individuality, but were essentialist about student culture. Implications We have implications for practitioners, e.g. to have professional developments that allow teachers to name and challenge white supremacy in CS. We also have implications for researchers, e.g. to investigate ways in which white students and teachers can benefit from anti-racist CS education.

Cross-Country Variation in (Binary) Gender Differences in Secondary School Students’ CS Attitudes: Re-Validating and Generalizing a CS Attitudes Scale

The current study compared American, Korean, and Indonesian middle and high school students’ CS attitudes. Concurrently, this study also examined whether the items in the CS attitudes scale exhibit country and gender measurement biases. We gathered data on CS attitudes from middle and high school students in the US, Korea, and Indonesia. The participating students took the same (translated) previously validated CS attitudes scale. We ran a unidimensional IRT, differential item functioning (DIF), a two-way ANOVA, and the Kruskal-Wallis H test. Despite the valid instrument, we found it inappropriate as is for international comparison studies because students from different countries interpreted some items differently. We then compared gender-based differences in CS attitudes across countries. The results revealed no significant differences between males and females in the Indonesian middle school data, whereas male students had significantly higher CS attitudes than female students in both American and Korean student data. Furthermore, we found the same pattern in gender differences in Korean and Indonesian high school students’ CS attitudes scores as in the middle school study. These findings underscore the importance of a country’s sociocultural context in influencing gap and diversity in secondary school students’ CS attitudes.

The influences of computer gameplay and social media use on computer science identity and computer science career interests

Computer gameplay and social media are the two most common forms of entertainment in the digital age. Many scholars share the assumption that leisure-time digital consumption is associated with computer science (CS) affinity, but there is a dearth of research evidence for this relationship. Female students generally spend less time on gaming and more time on social media than do male students, so a gender comparison perspective is helpful. Using multinomial logistic regression analysis on a national sample of 10,197 U.S. college students in introductory CS courses, we found that frequent computer gameplay was strongly associated with an increase in the probability of CS career interest relative to a Non-STEM career interest (β = -0.17, se = 0.06, p < .01) for both male (N = 7214) and female students (N = 2659). In contrast, increased social media use predicted a higher CS career interest relative to a Science/Engineering career interest (β = 0.12, se = 0.06, p < .05) for female students by 8%, however, a lower interest for male students by 4%.

Practitioner Perspectives on COVID-19’s Impact on Computer Science Education Among High Schools Serving Students from Lower and Higher Income Families

Research Problem. Computer science (CS) education researchers conducting studies that target high school students have likely seen their studies impacted by COVID-19. Interpreting research findings impacted by COVID-19 presents unique challenges that will require a deeper understanding as to how the pandemic has affected underserved and underrepresented students studying or unable to study computing. Research Question. Our research question for this study was: In what ways has the high school computer science educational ecosystem for students been impacted by COVID-19, particularly when comparing schools based on relative socioeconomic status of a majority of students? Methodology. We used an exploratory sequential mixed methods study to understand the types of impacts high school CS educators have seen in their practice over the past year using the CAPE theoretical dissaggregation framework to measure schools’ Capacity to offer CS, student Access to CS education, student Participation in CS, and Experiences of students taking CS. Data Collection Procedure. We developed an instrument to collect qualitative data from open-ended questions, then collected data from CS high school educators ( n = 21) and coded them across CAPE. We used the codes to create a quantitative instrument. We collected data from a wider set of CS high school educators ( n = 185), analyzed the data, and considered how these findings shape research conducted over the last year. Findings. Overall, practitioner perspectives revealed that capacity for CS Funding, Policy &amp; Curriculum in both types of schools grew during the pandemic, while the capacity to offer physical and human resources decreased. While access to extracurricular activities decreased, there was still a significant increase in the number of CS courses offered. Fewer girls took CS courses and attendance decreased. Student learning and engagement in CS courses were significantly impacted, while other noncognitive factors like interest in CS and relevance of technology saw increases. Practitioner perspectives also indicated that schools serving students from lower-income families had (1) a greater decrease in the number of students who received information about CS/CTE pathways; (2) a greater decrease in the number of girls enrolled in CS classes; (3) a greater decrease in the number of students receiving college credit for dual-credit CS courses; (4) a greater decrease in student attendance; and (5) a greater decrease in the number of students interested in taking additional CS courses. On the flip-side, schools serving students from higher income families had significantly higher increases in the number of students interested in taking additional CS courses.

Building a gender-inclusive secondary computer science program: teacher led and stakeholder supported

ABSTRACT Background Despite ongoing calls for prioritizing K-12 computer science (CS) education, an enduring gender gap exists. Objective We explored one high school CS program where female participation was consistently higher than state averages to better understand how the program was developed. Method Using a case study method, data were collected over three-months through interviews, observations, course documents, student reflections, and researcher reflections. Constant comparative analysis was employed to analyze data throughout and following data generation. Findings Recruitment and teacher support were key practices. Recruitment practices included letter writing campaigns and recruiting from introductory CS courses. Teacher support came from counselors, administrators, and other teachers. While the CS program was consistently more gender-inclusive, the focus when building the program had been on supporting all students, not only female students. Implications Recruitment should be active and purposeful, but using academic indicators for targeted recruitment campaigns can limit student exposure. Teachers need support for broadening participation, particularly from counselors and administrators, who must also be aware of what CS is and their role in these efforts. Opportunities for coteaching within CS programs can be beneficial for growth. Overall, broadening participation must be a holistic effort, supported by school-wide stakeholders, not only CS teachers.

Interaction effects of race and gender in elementary CS attitudes: A validation and cross-sectional study

Computer science (CS) initiatives for elementary students, including brief Hour of Code activities and longer in- and after-school programs that emphasize robotics and coding, have continued to increase in popularity. Many of these initiatives are intended to increase CS exposure to students who historically have been underrepresented in CS academic trajectories, including women and students of color. This study aimed at examining the gender and race difference in elementary students’ attitudes toward CS. To that end we developed and validated a survey instrument called Elementary Computer Science Attitudes (E-CSA) which consisted of the constructs of CS self-efficacy and outcome expectancy , through a combination of classical test theory and item response theory. The target audience for this instrument and study was upper elementary students (grades 4 and 5, ages 8 to 11). The E-CSA was found to be a gender and race bias-free instrument. A two-way ANOVA test was then used to answer research questions. We found no significant interaction effect between gender and race in the two constructs of CS Attitudes. We also did not see a significant difference based on race. However, a significant difference was found in both CS attitudes constructs based on gender, whereby male students had higher CS attitudes than female students. We discuss our findings from the perspective of the equity issue in CS education. Furthermore, we believe the E-CSA instrument can inform classroom-based interventions, the development of curricular materials, and reinforce findings from cross-sectional CS studies. • E-CSA instrument includes the constructs of CS self-efficacy and outcome expectancy. • The E-CSA was found to be a psychometrically gender bias-free instrument. • Found that male students had significantly higher CS attitudes than female students

Take space, make space: how students use computer science to disrupt and resist marginalization in schools

ABSTRACT Background and Context Overlaying Computer Science (CS) courses on top of inequitable schooling systems will not move us toward “CS for All.” This paper prioritizes the perspectives of minoritized students enrolled in high school CS classrooms across a large, urban school district in the Western United States, to help inform how CS can truly be for all. Objective This paper explores what student agency looks like while answering the research question “From the perspective of minoritized students historically underrepresented in computing, what makes a critical difference in their sense of agency in introductory CS high school classes?” Method Our research-practice partnership used qualitative data (including classroom observations, interviews, student artifacts, and video/photos) and surveys to surface the perspectives and visions of minoritized youth. Findings The research describes what student agency looks like as youth – who have had no prior CS learning experiences – use CS as a tool to resist marginalization and dehumanizing school contexts, while declaring their own “rightful presence” in CS classrooms. Implications Findings demonstrate the importance for CS curricula and pedagogy to center the lives of students in ways that are consequential for minoritized youth. This would support deeper engagement with content learning and student agency with computing.

A Framework for Using Hypothesis-Driven Approaches to Support Data-Driven Learning Analytics in Measuring Computational Thinking in Block-Based Programming Environments

Systematic endeavors to take computer science (CS) and computational thinking (CT) to scale in middle and high school classrooms are underway with curricula that emphasize the enactment of authentic CT skills, especially in the context of programming in block-based programming environments. There is, therefore, a growing need to measure students’ learning of CT in the context of programming and also support all learners through this process of learning computational problem solving. The goal of this research is to explore hypothesis-driven approaches that can be combined with data-driven ones to better interpret student actions and processes in log data captured from block-based programming environments with the goal of measuring and assessing students’ CT skills. Informed by past literature and based on our empirical work examining a dataset from the use of the Fairy Assessment in the Alice programming environment in middle schools, we present a framework that formalizes a process where a hypothesis-driven approach informed by Evidence-Centered Design effectively complements data-driven learning analytics in interpreting students’ programming process and assessing CT in block-based programming environments. We apply the framework to the design of Alice tasks for high school CS to be used for measuring CT during programming.

Sharing computer science education ideas

This article describes a unique Israeli-Russian project, in which Israeli high school computer science (CS) teachers promote curricular reform in the Russian region of Penza, based on the Israeli high school CS curriculum. The reform involves local schools, universities, the hi-tech industry and local government officials. It includes changes in courses, textbooks and other teaching materials. The Israeli teachers provided workshops to assist the Russian teachers in the assimilation of the reform. This collaboration may encourage other countries to collaborate and not necessarily re-invent the wheel; for some countries it can serve as a catalyst to assist in bringing computer science education into schools.

Democratizing computer science knowledge: transforming the face of computer science through public high school education

Despite the fact that computer science (CS) is the driver of technological innovations across all disciplines and aspects of our lives, including participatory media, high school CS too commonly fails to incorporate the perspectives and concerns of low-income students of color. This article describes a partnership program – Exploring Computer Science (ECS) – that directly counters this problem in our nation's second largest school district. With a mission of democratizing CS learning, we argue that despite the constraints of working within public schools, it is imperative to do so. We discuss the ECS program based on inquiry, culturally relevant curriculum, and equity-oriented pedagogy. We describe two ECS-affiliated projects that highlight the importance of authorship, purpose, and agency for student learning and engagement: DietSens using mobile technology to study community health, and a project in which students create video games about social issues. Our work offers a counter-narrative to those who have written off the possibilities of working within public schools and a debunking of the too widespread myth within our educational system that females and students of color are inherently uninterested in rigorous CS learning.

Digital Game-Based Learning in high school Computer Science education: Impact on educational effectiveness and student motivation

The aim of this study was to assess the learning effectiveness and motivational appeal of a computer game for learning computer memory concepts, which was designed according to the curricular objectives and the subject matter of the Greek high school Computer Science (CS) curriculum, as compared to a similar application, encompassing identical learning objectives and content but lacking the gaming aspect. The study also investigated potential gender differences in the game’s learning effectiveness and motivational appeal. The sample was 88 students, who were randomly assigned to two groups, one of which used the gaming application (Group A, N = 47) and the other one the non-gaming one (Group B, N = 41). A Computer Memory Knowledge Test (CMKT) was used as the pretest and posttest. Students were also observed during the interventions. Furthermore, after the interventions, students’ views on the application they had used were elicited through a feedback questionnaire. Data analyses showed that the gaming approach was both more effective in promoting students’ knowledge of computer memory concepts and more motivational than the non-gaming approach. Despite boys’ greater involvement with, liking of and experience in computer gaming, and their greater initial computer memory knowledge, the learning gains that boys and girls achieved through the use of the game did not differ significantly, and the game was found to be equally motivational for boys and girls. The results suggest that within high school CS, educational computer games can be exploited as effective and motivational learning environments, regardless of students’ gender.

The Evolving Culture of Computing: Similarity Is the Difference

Most studies of gender and computer science have been conducted (out of necessity) in gender-imbalanced environments. The findings often point to significant gender differences, leading the researchers to recommend strategies to meet these differences. One such recommendation is to adopt a female-friendly, contextual approach to curriculum development.1 In contrast, based on our recent and ongoing studies of undergraduate computer science (CS) students at Carnegie Mellon University, we hypothesize that in a more balanced environment, gender differences tend to dissolve. That is, the spectrum of interests, motivation, and personality types of men and of women becomes more alike than different. This leads us to be considerably more pragmatic in our recommendations for effective and positive change. Indeed, we believe that recommendations for curricular changes based on presumed gender differences can be misguided and may help reinforce, even perpetuate, stereotypes. Here, we describe some of the changes in the culture of computing as our undergraduate CS environment has become more balanced in three critical domains: gender, the mix of students and breadth of their interests, and the professional experiences afforded all students. Brief Background for the Evolving Culture In 1995, just 7percent (7 out of 96) of the entering freshmen CS majors at Carnegie Mellon were women. Since 1999, the percentage has increased nearly fivefold (on average, 45 out of 132), challenging trends across the country.2 Two major factors have contributed to the dramatic increase of women in CS at Carnegie Mellon: an outreach program for high school CS teachers that combined technical training with discussions of gender-gap issues and a broadened admissions policy (emphasizing diverse interests—along with high [End Page 110] achievement in mathematics and science—and de-emphasizing prior programming experience). To meet the needs of students with varying backgrounds, multiple entry routes were built into the first-year programming sequence.3 The subsequent creation of the proactive student organization Women@SCS has been catalytic in building an environment in which the new student body can flourish.4 Women@SCS explicitly provides crucial educational and professional experiences generally taken for granted by the majority in the community but typically unavailable for the minority participants.5 Many of these experiences are casual and often happen in social settings. For example, in an undergraduate CS program, male students often have the opportunity to discuss homework with roommates, with friends late at night, or over meals. Course and job information and recommendations are passed down from upperclassmen, from fraternity files, or from friends. Women students, being in the minority, do not have access to—in fact are often excluded from—these implicit and important advantages. As one proceeds into the professional world, similar phenomena occur. These key actions, and implications for other venues, are discussed further at the end of this paper. Our recent study, based on a set of interviews with seniors in the class of 2002, may be viewed to a limited degree as a follow-up to the intensive longitudinal studies of CS students at Carnegie Mellon carried out by Jane Margolis and Allan Fisher between 1995 and 1999.6 Their studies, funded by the Sloan Foundation and discussed in Unlocking the Clubhouse, were undertaken to help understand differences in male and female students' engagement (attachment, persistence, and detachment) with computer science, with a special focus on the gender imbalance in the field.7 A major goal was to devise and effect changes in recruitment, curriculum, pedagogy, and culture to encourage the broadest possible participation in the computing enterprise. Unlocking the Clubhouse paints a bleak picture for women in the undergraduate computer science program in the 1990s, one that still resonates with many CS programs across the nation. Margolis and Fisher note that for the most part, "women who were enthusiastic about computing find their confidence and interest extinguished in the college years."8 Consequently, many of the (few) women students who entered the...
