Objective Developing and validating a new instrument for assessing young children’s proficiency in the programming language ScratchJr, based on the Coding Stages framework. Method We used an iterative, design-based research approach to develop the Coding Stages Assessment (CSA), a one-on-one assessment capturing children’s technical skills and expressivity. We tested 118 five-to-eight-year-olds and used Classical Test Theory and Item Response Theory to evaluate the assessment’s psychometric properties. Findings The CSA has good to very good reliability. CSA scores were correlated with computational thinking ability, demonstrating construct validity. The items have good discrimination levels, and a variety of difficulty levels to capture different proficiency levels. Younger children tended to have lower scores, but even first graders can achieve the highest coding stage. There was no evidence of gender or age bias. Implications The CSA allows testing learning theories and curricula, which supports the implementation of Computer Science as a school subject. The successful remote administration demonstrates that it can be used without geographical restrictions.","PeriodicalId":45844,"journal":{"name":"Computer Science Education","volume":"32 1","pages":"388 - 417"},"PeriodicalIF":2.7,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08993408.2021.1956216","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42187439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent trend among these unplugged approaches is the use of tabletop games. While there are many commercial tabletop games on the market that are promoted as teaching computer science and/or computational skills, little is known about how these games are supposed to support learning. This study investigates the types of tabletop games that are currently being promoted as teaching computational thinking, who such games are marketed towards, and how game designs could provide opportunities for developing computational thinking. We conducted a content analysis to explore the type of tabletop games currently being created, their audiences, and the kinds of game mechanics and design features being implemented to teach computational thinking concepts. In this study, we created a taxonomy of computational thinking tabletop games that identified three primary categories (e.g. code building, code execution, and puzzle games) . Games that fall into our categories share similar learning claims, target audiences, and game mechanics. Our taxonomy offers a starting place for educators who want to explore the use of tabletop games for introducing computational thinking concepts in unplugged settings, suggestions for designers, and areas of investigation for researchers.","PeriodicalId":45844,"journal":{"name":"Computer Science Education","volume":"32 1","pages":"449 - 475"},"PeriodicalIF":2.7,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45680167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For studies with young adolescents as participants, manifested research philosophies are sometimes inconsistent with societal pluralisms. Objective Based on research literature from 2016 to early 2019 for CT|P in required science and engineering classes with youth ages 10-15 – a sensitive age range for cognitive and affective development – we wrote a literature review that argues for the use of more pluralistic and critical research philosophies, which will strengthen research design, implementation, and meta-inferences (Collins et al., 2012). Method We analyzed 20 qualifying studies per research philosophies common to mixed research, giving extra attention to studies that acknowledge cultural pluralisms, engage those pluralisms in conversation with each other, and ensure that historically marginalized populations have equiTable – not just equal – participation (Onwuegbuzie & Frels, 2013). Findings We found that studies consistently emphasized pragmatism-of-the-middle and communities of practice; sometimes operated within critical realist, pragmatism-of-the-right, or transformative-emancipatory philosophies; and rarely engaged in dialectical ways. Implications To avoid decontextualized or overly individualistic approaches that fail to address systemic and institutional social inequities (in education, housing, healthcare, policing, voting, etc.), future work should take more pluralistic and critical philosophical approaches. We highlight several exemplars in hope that research will support youth in maintaining and extending computational practices in culturally sustaining ways (Paris, 2012).","PeriodicalId":45844,"journal":{"name":"Computer Science Education","volume":"32 1","pages":"235 - 259"},"PeriodicalIF":2.7,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08993408.2021.1940787","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45477369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method We conducted semi-structured interviews with seven computer science (CS) teachers in upper secondary education (students aged 15–18). The data were analyzed qualitatively. Findings We found two patterns of variation in teachers’ PCK. First, we detected variation in the teachers’ goals related to their view of algorithms: they either focused on “thinking” about the algorithm as an object, or focused on “thinking and making”, where the algorithm is also regarded as a program. Second, we found variation in teachers’ knowledge about responding to differences between students, which may be generic or topic-specific. Furthermore, our findings reveal that teachers consider class discussions to play a significant role as an instructional method for provoking reflection.

Objective We examine the predictors of upward transfer computing students’ Ph.D. aspirations, focusing on how these patterns might be unique for upward transfer women. Method Relying on longitudinal survey data from upward transfer students across 15 research universities, we use logistic regression with interaction terms to identify the predictors of Ph.D. aspirations. Findings We found that Ph.D. aspirations were especially frequent among upward transfer women, 14% of whom aspired to earn a Ph.D. Other results highlight the importance of faculty encouragement for graduate study in predicting all upward transfer students’ Ph.D. aspirations. Beyond the direct role of such faculty encouragement, perceptions of computing faculty uniquely predicted Ph.D. aspirations for upward transfer women.

Findings Few studies have been conducted on the influence of emotions on learning programming. Research studies do not address gender differences. Research has been oriented along three main lines (a) determining what emotions are involved in the process of learning to program; (b) determining the behavioral patterns of novice students and how from this behavior their emotions can be identified; and (c) developing intelligent systems that respond adaptively to students’ emotions.
