Promoting transfer and an integrated understanding for pre-service teachers of technology education

The ability of pre-service teachers (PSTs) to transfer learning between subjects and contexts when problem solving is critical for developing their capability as technologists and teachers of technology. However, a growing body of literature suggests this ability is often assumed or over-estimated, and rarely developed explicitly within courses or degree programmes. The nature of the problems tackled within technology are such that solutions draw upon knowledge from a wide range of contexts and subjects, however, the internal organization and structure of institutions and schools tends to compartmentalize rather integrate these. Providing a knowledge base and strategies to enhance PSTs’ awareness of and skills in transferring knowledge may allow for a more integrated understanding to develop. The importance of developing this ability to transfer knowledge is heightened as PSTs will, in turn, be responsible for developing the similar capabilities of their future students. This paper begins by considering problem solving in technology education and some of the issues associated with learning transfer. Thereafter, a framework and strategy for better integrating learning between courses is described and forms the basis for developments in an initial teacher education degree programme for technology education. Provisional data from evaluations and PSTs’ work indicated a positive effect in enhancing their thinking and additional data collected in the form of questionnaires, interviews and course work further illuminate this finding. It is argued that the development framework and approach enhances PSTs’ mental models of teaching technology and offers a significant step forward in promoting skills in the transfer of future learning between subjects; something increasingly critical for 21st century STEM Education

Considering the Smartphone Learner: developing innovation to investigate the opportunities for students and their interest

Ownership of mobile smartphones amongst the general consumer, professionals and students is growing exponentially. The potential for smartphones in education builds upon experience described in the extensive literature on mobile learning from the previous decade which suggests that the ubiquity, multi-functionality and connectivity of mobile devices offers a new and potentially powerful networked learning environment. This paper reports on a collaborative study conducted by an undergraduate student with the support of two members of academic staff. The research sought to establish the extent to which students are autonomously harnessing smartphone technology to support their learning and the nature of this use. Initial findings were explored through student interviews. The study found that students who own smartphones are largely unaware of their potential to support learning and, in general, do not install smartphone applications for that purpose. They are, however, interested in and open to the potential as they become familiar with the possibilities for a range of purposes. The paper proposes that more consideration needs to be given to smartphones as platforms to support formal, informal and autonomous learner engagement. The study also reflects on its collaborative methodology and the challenges associated with academic innovation

Evaluating the Stream Control Transmission Protocol Using Uppaal

The Stream Control Transmission Protocol (SCTP) is a Transport Layer protocol that has been proposed as an alternative to the Transmission Control Protocol (TCP) for the Internet of Things (IoT). SCTP, with its four-way handshake mechanism, claims to protect the Server from a Denial-of-Service (DoS) attack by ensuring the legitimacy of the Client, which has been a known issue pertaining to the three-way handshake of TCP. This paper compares the handshakes of TCP and SCTP to discuss its shortcomings and strengths. We present an Uppaal model of the TCP three-way handshake and SCTP four-way handshake and show that SCTP is able to cope with the presence of an Illegitimate Client, while TCP fails. The results confirm that SCTP is better equipped to deal with this type of attack.Comment: In Proceedings MARS 2017, arXiv:1703.0581

Cryptoart: Ethical Challenges of the NFT Revolution

The digital transformation of the art world has become a revolution for the sector. Cryptoart, based on non-fungible tokens (NFT), is attracting the attention of artists, collectors and enthusiasts for its ability to tokenise any element that can be sold as art in the digital market. That means it is able to become a scarce resource and an economic asset by encapsulating the market value of a piece of digital art, which may or may not have a reference in the real world. This study will delve into the ethical aspects underlying what is known as the NFT Revolution, particularly impacts related to the abuse or destruction of cultural heritage, speculation and the generation of economic bubbles and environmental unsustainability

Depression: Illness, Insight, and Identity

Depression needs to be understood within interdisciplinary scientific, biopsychosocial, therapeutic frameworks, but it also has a moral dimension. The tendency to oppose moral and therapeutic perspectives, as well as to replace moral outlooks with mental-health outlooks, handicaps thinking about depression and many other topics. John Stuart Mill\u27s midlife crisis illustrates how an experience of depression can be both a sickness and a source of moral insight. Furthermore, therapy has a moral dimension, and conversely a humane outlook is interwoven with health-oriented approaches and avoids excessive blaming and guilt. Complicating matters, depression sometimes undermines moral autonomy, and there is a continuum between healthy and unhealthy depression

Digital Art as ‘Monetised Graphics:’ Enforcing Intellectual Property on the Blockchain

In a global economic landscape of hyper-commodification and financialisation, efforts to assimilate digital art into the high-stakes commercial art market have so far been rather unsuccessful, presumably because digital art works cannot easily assume the status of precious object worthy of collection. This essay explores the use of blockchain technologies in attempts to create proprietary digital art markets in which uncommodifiable digital art works are financialised as artificially scarce commodities. Using the decentralisation techniques and distributed database protocols underlying current cryptocurrency technologies, such efforts, exemplified here by the platform Monegraph, tend to be presented as concerns with the interest of digital artists and with shifting ontologies of the contemporary work of art. I challenge this characterisation, and argue, in a discussion that combines aesthetic theory, legal and philosophical theories of intellectual property, rhetorical analysis, and research in the political economy of new media, that the formation of proprietary digital art markets by emerging commercial platforms such as Monegraph constitutes a worrisome amplification of long-established, on-going efforts to fence in creative expression as private property. As I argue, the combination of blockchain-based protocols with established ambitions of intellectual property policy yields hybrid conceptual-computational financial technologies (such as self-enforcing smart contracts attached to digital artefacts) that are unlikely to empower artists, but which serve to financialise digital creative practices as a whole, curtailing the critical potential of the digital as an inherently dynamic and potentially uncommodifiable mode of production and artistic expression

Ethical rooms for maneuver and theirprospects vis á vis the current ethical food policies in Europe

In this paper I want to show that consumer concerns can be implemented in food chains by organizing ethical discussions of conflicting values that include them as participators. First, it is argued that there are several types of consumer concerns about food and agriculture that are multi-interpretable and often contradict each other or are at least difficult to reconcile without considerable loss. Second, these consumer concerns are inherently dynamic because they respond to difficult and complex societal and technological situations and developments. For example, because of the rising concern with global warming, carbon dioxide absorption of crops is now attracting public attention, which means that new requirements are being proposed for the environmentally friendly production of crops. Third, there are different types of consumers, and their choices between conflicting values differ accordingly. Consumers use different weighing models and various types of information in making their food choices. Changing food chains more in accordance with consumer concerns should at least take into account the multi-interpretable, dynamic, and pluralist features of consumer concerns, for example, in traceability schemes. In discussing usual approaches such as codes, stakeholder analysis, and assurance schemes, I conclude that these traditional approaches can be helpful. However, in cases of dynamic, pluralistic, and uncertain developments, maintaining some pre-existing evaluating scheme or some clear cut normative hierarchy, such as codes or assurance schemes, can be disastrous in undermining new ethical desirable initiatives. Instead of considering ethical standards and targets as fixed, which is done with codes and schemes, it is more fruitful to emphasize the structure of the processes in which ethical weighing of relevant consumer concerns get shaped. The concept of ¿Ethical Room for Maneuver¿ (ERM) is constructed to specify the ethical desirable conditions under which identification and weighing of paramount values and their dilemmas can be processed. The main aims of the ERM are making room in all the links of the food chain for regulating and implementing the relevant consumer concerns by (1) balancing and negotiating, (2) supporting information systems that are relevant and communicative for various consumer groups and (3) organizing consumer involvement in the links of the food chain. The social and political context of agriculture and food production, particularly in Europe, gives ample opportunity for implementing several types of Ethical Rooms for Maneuver. Finally, I discuss several types of Ethical Rooms for Manoeuvre in the food chains that can be communicated by means of specific traceability schemes to less involved stakeholders with the potential consequence that the stakeholders will be motivated to be more involve
