Defining the Competencies, Programming Languages, and Assessments for an Introductory Computer Science Course

The purpose of this study was to define the competencies, programming languages, and assessments for an introductory computer science course at a small private liberal arts university. Three research questions were addressed that involved identifying the competencies, programming languages, and assessments that academic and industry experts in California’s Central Valley felt most important and appropriate for an introduction to computer science course. The Delphi methodology was used to collect data from the two groups of experts with various backgrounds related to computing. The goal was to find consensus among the individual groups to best define aspects that would best comprise an introductory CS0 course for majors and non-majors. The output would be valuable information to be considered by curriculum designers who are developing a new program in software engineering at the institution. The process outlined would also be useful to curriculum designers in other fields and geographic regions who attempt to address their local education needs. Four rounds of surveys were conducted. The groups of experts were combined in the first round to rate the items in the straw models determined from the literature and add additional components when necessary. The academic and industry groupings were separated for the remainder of the study so that a curriculum designer could determine not only the items deemed most important, but also their relative importance among the two distinct groups. The experts selected items in each of the three categories in the second round to reduce the possibilities for subsequent rounds. The groups were then asked to rank the items in each of the three categories for the third round. A fourth round was held as consensus was not reached by either of the groups for any of the categories as determined by Kendall’s W. The academic experts reached consensus on a list of ranked competencies in the final round and showed a high degree of agreement on lists of ranked programming languages and assessments. Kendall’s W, values, however, were just short of the required 0.7 threshold for consensus on these final two items. The industry experts did not reach consensus and showed low agreement on their recommendations for competencies, programming languages, and assessments

In Search of a “Fair Explanation”: Helping Young People to Consider the Possibilities, Limitations, and Risks of Computer- and Data-Mediated Systems

Significant resources have been directed towards K-12 computing and data education over the past ten years, as part of what has come to be known as the CSforAll initiative. This initiative has focused on raising awareness of computing education among parents and students, developing situated learning progressions that resonate with many different interests and pursuits, training teachers, and addressing issues of underrepresentation in computing among females and racial minorities. In this dissertation, I argue that as the CSforAll initiative continues to expand, it is important for the education community to also reflect on the forms of knowledge that are believed to be essential, and the presumed benefits of computing and data education. Specifically, how might the goal of producing citizens with robust computing and data literacies change what is considered to be fundamental to a computing education; as well as the kinds of contexts in which computing and data science are situated?I use the term sociotechnical literacy to name this vision for computing education, which I define as a broad set of social and technical practices, strategies, ideas, and dispositions that can help people to reason about the computer-mediated systems that shape their everyday lives. As the term suggests, I argue that it is important for learners to engage with technical ideas as well as their social applications and implications. To examine what this might mean for teaching and learning, I describe two design experiments that I conducted with young people (ages 14 – 22). Each approach aimed to make the applications of computing primary (rather than treating applications as the backdrop from which the abstractions of computation are motivated), so that learners could examine some of the specific ways in which data and computing might be directed to particular goals, subject to real possibilities and constraints, and in relation to alternative forms of participation. I examine the possibilities and limitations of each approach. I also analyze some of the assumptions that framed the design experiments – which were naïve, but also reflective of a broader ethos that pervades CSforAll. I reflect on what these studies collectively reveal about the possibilities, limitations, and risks of data and computing, as situated in the lives of young people; as well as what this might mean for helping young people develop a robust sociotechnical literacy. There are very real limits to what can be accomplished with computing and data alone. There are also significant benefits and risks associated with the many sociotechnical systems that shape our lives. As such, I argue that rather than positioning computing education as a remedy to various social ills, we instead offer young people a fair explanation of what computing is and is not capable of, grounded within specific contexts involving real people. I conclude with what this fair explanation might include, and how it might be fostered

Specialised Languages and Multimedia. Linguistic and Cross-cultural Issues

none2noThis book collects academic works focusing on scientific and technical discourse and on the ways in which this type of discourse appears in or is shaped by multimedia products. The originality of this book is to be seen in the variety of approaches used and of the specialised languages investigated in relation to multimodal and multimedia genres. Contributions will particularly focus on new multimodal or multimedia forms of specialised discourse (in institutional, academic, technical, scientific, social or popular settings), linguistic features of specialised discourse in multimodal or multimedia genres, the popularisation of specialised knowledge in multimodal or multimedia genres, the impact of multimodality and multimediality on the construction of scientific and technical discourse, the impact of multimodality/multimediality in the practice and teaching of language, the impact of multimodality/multimediality in the practice and teaching of translation, new multimedia modes of knowledge dissemination, the translation/adaptation of scientific discourse in multimedia products. This volume contributes to the theory and practice of multimodal studies and translation, with a specific focus on specialized discourse.Rivista di Classe A - Volume specialeopenManca E., Bianchi F.Manca, E.; Bianchi, F

Introducing Computational Thinking in K-12 Education: Historical, Epistemological, Pedagogical, Cognitive, and Affective Aspects

Introduction of scientific and cultural aspects of Computer Science (CS) (called "Computational Thinking" - CT) in K-12 education is fundamental. We focus on three crucial areas. 1. Historical, philosophical, and pedagogical aspects. What are the big ideas of CS we must teach? What are the historical and pedagogical contexts in which CT emerged, and why are relevant? What is the relationship between learning theories (e.g., constructivism) and teaching approaches (e.g., plugged and unplugged)? 2. Cognitive aspects. What is the sentiment of generalist teachers not trained to teach CS? What misconceptions do they hold about concepts like CT and "coding"? 3. Affective and motivational aspects. What is the impact of personal beliefs about intelligence (mindset) and about CS ability? What the role of teaching approaches? This research has been conducted both through historical and philosophical argumentation, and through quantitative and qualitative studies (both on nationwide samples and small significant ones), in particular through the lens of (often exaggerated) claims about transfer from CS to other skills. Four important claims are substantiated. 1. CS should be introduced in K-12 as a tool to understand and act in our digital world, and to use the power of computation for meaningful learning. CT is the conceptual sediment of that learning. We designed a curriculum proposal in this direction. 2. The expressions CT (useful to distantiate from digital literacy) and "coding" can cause misconceptions among teachers, who focus mainly on transfer to general thinking skills. Both disciplinary and pedagogical teacher training is hence needed. 3. Some plugged and unplugged teaching tools have intrinsic constructivist characteristics that can facilitate CS learning, as shown with proposed activities. 4. Growth mindset is not automatically fostered by CS, while not studying CS can foster fixed beliefs. Growth mindset can be fostered by creative computing, leveraging on its constructivist aspects

Reuse and Repurposing of Online Digital Learning Resources within UK Higher Education: 2003-2010

This research set out to examine developments in reuse and repurposing of online digital resources within higher education (HE) in the United Kingdom (UK) over a period (2003-2010), when the emphasis of educational resource reuse and repurposing activity shifted from reusable learning objects (RLO) to open educational resources (OER). It aims to contribute to understanding of this transition, and locates this shift within a broader picture of UK HE activity within the UK, and a wider understanding of reuse of learning resources in digital, online form. The research presents a review and critical examination of the environment in which reuse practice occurred. It does this through macroenvironmental, mesoenvironmental and microenvironmental level reviews. The microenvionmental review is presented through research analysis of five case examples from UK HE and a sixth example from HE in Ireland. The mesoenvironmental review examines the significant changes in resource facilitation and practice during the research period. This thesis is particularly concerned with identifying and understanding how reuse of digital online learning resources was facilitated in practice, and whether reuse occurred, or occurred in the form(s) anticipated. The thesis identifies and examines themes and factors which appeared to have influenced, or had potential to influence, reuse in each case. Cross-case comparison offers a synthesis of the research observations. Finally, a structured approach to classifying factors is suggested based on this research. This leads to generalisable recommendations of how to facilitate digital online resource reuse in the future
