The emerging field of Data Science has had a large impact on science and society. This has led to over a decade of calls to establish a corresponding field of Data Science Education. There is still a need, however, to more deeply conceptualize what a field of Data Science Education might entail in terms of scope, responsibility, and execution. This special issue explores how one distinguishing feature of Data Science—its focus on data collected from social and environmental contexts within which learners often find themselves deeply embedded—suggests serious implications for learning and education. The learning sciences is uniquely positioned to investigate how such contextual embeddings impact learners’ engagement with data including conceptual, experiential, communal, racialized, spatial, and political dimensions. This special issue demonstrates the richly layered relationships learners build with data and reveals them to be not merely utilitarian mechanisms for learning about data, but a critical part of navigating data as social text and understanding Data Science as a discipline. Together, the contributions offer a vision of how the learning sciences can contribute to a more expansive, agentive and socially aware Data Science Education. 相似文献

ABSTRACTAlthough globalisation's influences on education have contributed to cultural evolution, economic development and social progress, they also have generated mixed reactions among Muslim populations. This article shows how globalisation has facilitated the infiltration of Western culture into Muslim societies through modern educational modes. Some conservative Muslim communities perceive this infiltration as a threat to Islamic values, creating a culture of fear. Combined with decades of colonisation, social injustice, and defeat, this fear has triggered a state of hatred and anger motivating the rise of extremism, terrorism, and retaliatory attacks on education. 相似文献

This article examines petitions submitted to the Egyptian state by students and parents over the span of a century. These sources reveal that Egyptians from across the economic spectrum were shifting their construction of schooling in response to changing political and educational policies and evolving conceptions of educational need. Over the course of the nineteenth and early twentieth centuries, parents and students were increasingly appealing to discourses concerning education, girls’ schooling and nationalism as a way to frame their personal pursuits as an extension of national advancement. As a result, petitioners saw education not as a matter of charity or luxury, but rather as a fundamental way to prevent ‘losing’ a brighter future. Ultimately, this shift in the concept of educational need underwrote the development of mass educational systems of the twentieth century as a cornerstone of the relationship between even the poorest of citizens and the Egyptian state. 相似文献

In computational modeling activities, learners are expected to discover the inner workings of scientific and mathematical systems: First elaborating their understandings of a given system through constructing a computer model, then “debugging” that knowledge by testing and refining the model. While such activities have been shown to support science learning, difficulties building and using computational models are common and reduce learning benefits. Drawing from Collins and Ferguson (Educ Psychol 28(1):25–42, 1993), we conjecture that a major cause for such difficulties is a misalignment between the epistemic games (modeling strategies) learners play, and the epistemic forms (model types) a given modeling environment is designed to support. To investigate, we analyzed data from a study in which ten groups of U. S. fifth graders (n = 28) worked to create stop motion animations and agent-based computational models (ABMs) to discover the particulate nature of matter. Content analyses revealed that (1) groups that made progress—that is, that developed increasingly mechanistic, explanatory models—focused on elements, movement, and interactions when developing their models, a strategy well-aligned with both animation and ABM; (2) groups that did not make progress focused on sequences of phases, a strategy well-aligned with animation but not with ABM; and (3) struggling groups progressed when they received guidance about modeling strategies, but not when they received guidance about model content. We present summary analyses and three vignettes to illustrate these findings, and share implications for research and curricular design. 相似文献

This study investigates the status of women engineers in the Middle East, considering women engineers in Lebanon as a case study. The author investigated the following questions: What are the influences behind females’ decisions to choose engineering as their major course of study? What are the motives behind this decision? What are the perceptions of females regarding the essential skills for a successful engineering career? An online survey consisting of Likert-scale items was completed by 327 female engineers who graduated from universities in Lebanon and now work in various locations around the world. A genuine interest in the field appeared to be the main influence in the participants’ decisions to choose engineering profession. The potential for professional growth was the leading motivator for choosing engineering. Although participants reported that they possessed adequate theoretical knowledge and technical skills before graduation, in the actual practice of engineering, they noted weaknesses in creativity and innovation. 相似文献

ABSTRACTScience educators demonstrated that students’ framings – their expectations of what is going on – influence how they participate, and what science knowledge they reveal, in clinical interviews. This paper complements research that explores how interviewers are likely to affect student framings, by exploring how subtler interactions can lead students to change their framings, and thus their behaviour, in unexpected ways. We present data from interviews with two students, Sarah and Omar, as they reasoned about evaporation and condensation. Sarah demonstrated spontaneous changes in how she participated over the course of the interview, whereas Omar demonstrated subtler changes that existing methods may not capture. These changes affected the nature of scientific knowledge and reasoning demonstrated by each participant, but could not be fully explained by response to interviewer behaviour. We use the constructs of footing and positioning theory to examine how students participated during the interviews, and how this affected the ways they demonstrated knowledge and reasoning about the interview topic. In both cases, footing and positioning theory allowed us to better understand the dynamic ways students engage in the interview. This paper contributes new methods for analysing complex interview dynamics, and suggests situations for which such methods are necessary. 相似文献

Due to the high market demands for professional engineers in the Arab oil-producing countries, the appetite of Middle Eastern students for high-paying jobs and challenging careers in engineering has sharply increased. As a result, engineering programmes are providing opportunities for more students to enrol on engineering courses through lenient admission policies that do not compromise academic standards. This strategy has generated an influx of students who must be carefully educated to enhance their professional knowledge and social capital to assist in future earthquake-disaster risk-reduction efforts. However, the majority of Middle Eastern engineering students are unaware of the valuable acquired engineering skills and knowledge in building the resilience of their communities to earthquake disasters. As the majority of the countries in the Middle East are exposed to seismic hazards and are vulnerable to destructive earthquakes, engineers have become indispensable assets and the first line of defence against earthquake threats. This article highlights the contributions of some of the engineering innovations in advancing technologies and techniques for effective disaster mitigation and it calls for the incorporation of earthquake-disaster-mitigation education into academic engineering programmes in the Eastern Mediterranean region. 相似文献

Lipid–oligonucleotide conjugates (LONs) are powerful molecular-engineering materials for various applications ranging from biosensors to biomedicine. Their unique amphiphilic structures enable the self-assembly and the conveyance of information with high fidelity. In particular, LONs present remarkable potential in measuring cellular mechanical forces and monitoring cell behaviors. LONs are also essential sensing tools for intracellular imaging and have been employed in developing cell-surface-anchored DNA nanostructures for biomimetic-engineering studies. When incorporating therapeutic oligonucleotides or small-molecule drugs, LONs hold promise for targeted therapy. Moreover, LONs mediate the controllable assembly and fusion of vesicles based on DNA-strand displacements, contributing to nanoreactor construction and macromolecule delivery. In this review, we will summarize the general synthesis strategies of LONs, provide some characterization analysis and emphasize recent advances in bioanalytical and biomedical applications. We will also consider the relevant challenges and suggest future directions for building better functional LONs in nanotechnology and materials-science applications. 相似文献
