关键词： Employer attractiveness   Job pursuit intentions   Work-life balance   Employee recommendation   Job attributes   Alternative work arrangement  

摘要： Drawing on signaling theory (Spence 1978), we propose that communicating work-life balance benefits offered along with favorable employee recommendations and valued job attributes could be construed as signals organizations deliberately use to influence potential applicants' perceptions of employer attractiveness and enhance job pursuit intentions. We test these ideas in two experiments. In study 1, using carefully constructed vignettes to manipulate work-life balance (WLB) benefits, employee recommendation, and job attributes in a 2 x 2 x 2 between-subjects design and with data gathered from 320 Indian MBA students, we found support for the direct and interactive effects of these variables on employer attractiveness. In study 2, using a 3 x 2 x 2 between-subjects design and data from 360 Indian MBA students, we examined the influence of three different alternative work arrangements, a form of WLB benefit, and how such benefits interact with employee recommendations and job attributes to influence job pursuit intentions. We discuss implications for theory, research, and practice.

关键词： Computer science education   programming   teacher preparation   pre-service teachers   programming education  

摘要： This study investigates pre-service computer science (CS) teachers' perspectives on the factors affecting their programming abilities, concerns about their future professional lives, and pedagogical suggestions for effective programming teaching. The participants of the study were twenty-eight pre-service CS teachers studying at eighteen different universities in Turkiye. The data was gathered with a questionnaire consisting of open-ended questions. Results showed that inherent programming challenges, personal factors, and quality of undergraduate education affected pre-service CS teachers' abilities in programming teaching. They were concerned about their professional lives relating to programming teaching, keeping up with technological innovations, pedagogical concerns, and teaching practice. They also suggested pedagogical approaches that could be used in programming teaching under two categories, namely basic programming teaching, and teaching principles and techniques. The study contributes to the development of programming teaching by shedding light on the current perspectives of pre-service CS teachers on programming education.

关键词： Co-design   Computational empowerment   Computer science education   Physical computing   Trading zones   Visual programming  

摘要： In this paper we build on a conceptual framing of computational empowerment that seeks to provide alternative endpoints for computer science (CS) education beyond degree attainment and job placement. But, as opposed to a teleological framing that prioritizes ends, we propose using the metaphor of trading zones to construct a framing for computational empowerment that is based on collaborative multi-directional exchanges of resources and knowledge between people with different expertise. This leaves the co-design and implementation of CS education open to emergent directions and possibilities. Using a descriptive case study methodology, we detail trading zones in two different co-design projects that sought to situate CS education in relationship to cultural contexts through multi-directional exchanges of resources and knowledge: (1) a co-design project in a youth boxing gym with coaches, mentors, and staff;(2) a co-design project in a high school barbering program with a barbering instructor and barbering students. Our findings show that the metaphor is useful for the concept of computational empowerment in ways that are reflexive and interventionist. © 2023 Elsevier B.V.

关键词： diversity   computer science   diversity-aware technology   Black feminism   critical race theory  

摘要： Diversity has become increasingly relevant in computer science and technology development, both in terms of inclusive design teams and as a concept used to design "diversity-aware" technologies. The latter part has received less attention and notions of diversity leveraged to design technologies remain understudied. This paper critically examines diversity concepts employed by computer scientists and designers by reviewing 120 articles in two subfields of computer science: personalized recommendations and human-computer interaction. Drawing on Black feminism and critical race theory-inspired literature, I offer a critique of demographic and cultural user representations and underscore the shortcomings of diversity as a strategy to increase user satisfaction and fairness. Particularly concerning is the unreflected use of binary, static, and individual-level diversity concepts in the design of technologies. Such concepts render structural inequalities between and within groups of users invisible and thereby risk reinforcing existing injustices. The paper closes with considerations on whether and how diversity concepts can be leveraged by designers in a social justice-oriented manner.

关键词： Computer science   Coding   Computational thinking   Curriculum  

摘要： In this article, the relatively new phenomenon of integrating coding and computer science (CS) related concepts and skills into the K-8 grades is analysed through a comparative analysis of related provincial curriculum initiatives in Canada. First, provincial K-8 curricula that include coding and CS related concepts and skills are identified, as well as the placement of these components within the provincial policy documents. This is followed by a comparative analysis of stated aims and objectives of the curriculum components, and an analysis of the selected concepts and skills themselves. Throughout this analysis, context is provided by theory in the field, as well as the general approaches from jurisdictions outside of Canada, which have been found in the literature. What results is a comparative analysis of this nascent curriculum topic as well as important insights for educators, policy makers, and researchers alike. Dans cet article, par le biais d'un examen comparatif des initiatives provinciales connexes en matiere de programmes d'etudes en vigueur au Canada, on analyse le phenomene relativement recent de l'integration des competences et des concepts lies a l'informatique dans les classes de la maternelle a la 8e annee. On cerne tout d'abord les programmes provinciaux de la maternelle a la 8e annee qui incluent le codage et les competences et concepts qui y sont associes, ainsi que l'endroit ou se retrouvent ces elements dans les documents enoncant les politiques provinciales. Vient ensuite une analyse comparative des buts et objectifs declares des elements faisant partie du programme, ainsi qu'un examen des competences et des concepts choisis. Tout au long de cette analyse, le contexte provient de la theorie liee au domaine ainsi que des approches generales relevant de competences situees hors du Canada trouvees dans la documentation. Il en resulte une analyse comparative de ce sujet particulier (a l'etat naissant) du programme d'etude ainsi que des connaiss

摘要： Today, there is a great variety of learning techniques and methodologies: traditional lectures, role-plays, group dynamics, project-based learning, simulations, educational games, and so on. Regarding technology-enhanced learning, the educational usage of virtual reality is innovative and the initiatives carried out suggest that this technology is an appealing medium for young people that facilitates an active and effective teaching. On the other hand, agile methodologies are widely spread across the IT industry and it is necessary to look for the best techniques to learn them in the most appropriate way. This contribution presents a virtual reality serious video game, named ScrumVR, which aims to teach the key aspects of the most widespread agile methodology for software development: Scrum. To do so, this video game tries to gets players closer to their first weeks of work within a Scrum team. The empirical results, gathered through a case study conducted with 78 software engineering students and supported by instruments, such as prepost tests and questionnaires, indicate that ScrumVR facilitates the learning of the roles, meetings, artifacts, and practices employed in Scrum, and contributes to enhance student's motivation and the whole learning experience.

关键词： computer science   approximate symmetry   partial symmetry   local symmetry   point cloud   voxel   line segment  

摘要： The paper presents a new algorithm for reflection symmetry detection, which is specialized to detect maximal symmetric patterns in an Earth observation (EO) dataset. First, we stress the particularities that make symmetry detection in EO data different from detection in other geometric sets. The EO data acquisition cannot provide exact pairs of symmetric elements and, therefore, the approximate symmetry must be addressed, which is accomplished by voxelization. Besides this, the EO data symmetric patterns in the top view usually contain the most useful information for further processing and, thus, it suffices to detect symmetries with vertical symmetry planes. The algorithm first extracts the so-called interesting voxels and then finds symmetric pairs of line segments, separately for each horizontal voxel slice. The results with the same symmetry plane are then merged, first in individual slices and then through all the slices. The detected maximal symmetric patterns represent the so-called partial symmetries, which can be further processed to identify global and local symmetries. LiDAR datasets of six urban and natural attractions in Slovenia of different scales and in different voxel resolutions were analyzed in this paper, demonstrating high detection speed and quality of solutions.

关键词： computer science   education 4   0   learning design   teaching competencies  

摘要： Education 4.0 is a recently introduced concept focused on innovation, novelty, use of technology and connections with employment and industry. In particular, in engineering disciplines like computer science (CS) it is essential that educators keep up to date with industry developments. Indeed, how CS educators effectively design and implement innovative teaching and learning deserves more systematic attention. This study aims to catalogue and synthesise learning design approaches to teaching and learning within CS: (1) Which innovative pedagogic approaches are used in teaching of CS? (2) Which approaches align with Education 4.0? (3) What skills and competences do educators require to align CS teaching with Education 4.0? Our systematic literature review (SLR) included CS papers published between 2016 and 2020. Two hundred and thirty-one studies were identified of which 66 were included in the final phase, which were coded by a multidisciplinary team. The findings indicated that many CS educators included Education 4.0 learning design elements. We found a clear distinctive three-cluster solution: (1) EDU4 light, (2) project-based/hands-on learning and (3) full EDU4 (refer to Reference [7] conceptualisation, while Education 4.0 refers to our own definition [Reference 71]. These findings suggest three broad flavours when designing innovative CS practices, which might help educators align their practice.
