A working party of academics from both professional safeguarding backgrounds and research backgrounds developed and wrote ethical guidelines on safeguarding children in research on behalf of their faculty research ethics committee. The working party encountered a lack of useful precedents while developing the guidelines leading to a lengthy process of debate and consideration of the issues. This paper explores the various issues and dilemmas arising during this process, particularly the tension between safeguarding children from abuse and maintaining research confidentiality. One (...) of the main areas of discussion was how to establish the limits of confidentiality without compromising the research in hand. The role and responsibilities of researchers in supporting children's welfare, and the development of procedures for ensuring that safeguarding is effective are discussed as key elements. In addition, the issues researchers may face when determining thresholds for intervention are considered alongside the uncertainties created by considerations of the extent to which children can give informed consent in research contexts. The paper reflects the process of considering these issues and the conclusions the working party drew as to how best to support children's welfare during research. It also outlines the key elements of the guidelines and the structures developed to ensure researchers could get advice if suspected child abuse became an issue in their research. The paper includes a short version of the guidelines which were eventually approved across the Higher Education Institute. (shrink)

By its very nature ethnography is an emergent methodology. To be ethical the ethnographer needs to manage research ethics in-situ. This need to manage ethical dilemmas as they arise often comes into conflict with increased ethical regulation and procedures from ethics review boards that require the researcher to foresee ethical quandaries before data collection commences. These regulations can constrain the emerging purpose of the study, evolving means of data collection and multifaceted ways of interacting with participants that are seen as (...) being the strengths of undertaking an ethnographic approach. 0The chapters in this volume problematise this tension and highlight the importance of managing ethics in-situ by reflecting on recently completed and current projects drawing out ethical dilemmas relating to data ownership, dissemination, representation, social justice and managing ethnographic studies in the midst of a global pandemic and Covid-19 lockdowns. 0Reflecting on these experiences of doing educational ethnography with children and young people, drawing on a diverse range of studies conducted in England, Scotland, South America, India, and the Basque Country, this volume argues that administrative and conceptual change is needed to ensure that ethics does not become a tick box exercise but that ethnographers commit fully to conscientiously managing ethics in-situ.

Exploitation locates what it is we recognize as bad when we judge a situation to be exploitative. Ideal for courses in social and political philosophy, public policy, or political science.

Offers an analysis of three strongly contrasting primitive civilizations, showing how behavior is influenced by custom and tradition.

Charles Taylor is one of the most influential and prolific philosophers in the English-speaking world today. The breadth of his writings is unique, ranging from reflections on artificial intelligence to analyses of contemporary multicultural societies. This thought-provoking introduction to Taylor's work outlines his ideas in a coherent and accessible way without reducing their richness and depth. His contribution to many of the enduring debates within Western philosophy is examined and the arguments of his critics assessed. Taylor's reflections on the topics (...) of moral theory, selfhood, political theory and epistemology form the core chapters within the book. Ruth Abbey engages with the secondary literature on Taylor's work and suggests that some criticisms by contemporaries have been based on misinterpretations and suggests ways in which a better understanding of Taylor's work leads to different criticisms of it. The book serves as an ideal companion to Taylor's ideas for students of philosophy and political theory, and will be welcomed by the non-specialist looking for an authoritative guide to Taylor's large and challenging body of work.

In attempting to derive irreversible macroscopic thermodynamics from reversible microscopic dynamics, Boltzmann inadvertently smuggled in a premise that assumed the very irreversibility he was trying to prove: ‘molecular chaos.’ The program of ‘Einselection’ within Everettian approaches faces a similar ‘Loschmidt’s Paradox’: the universe, according to the Everettian picture, is a closed system obeying only unitary dynamics, and it therefore contains no distinguishable environmental subsystems with the necessary ‘phase randomness’ to effect einselection of a pointer observable. The theoretically unjustified assumption of (...) distinguishable environmental subsystems is the hidden premise that makes the derivation of einselection circular. In effect, it presupposes the ‘emergent’ structures from the beginning. Thus the problem of basis ambiguity remains unsolved in Everettian interpretations. (shrink)

Heidegger argues that modern technology is quantifiably different from all earlier periods because of a shift in ethos from in situ craftwork to globalised production and storage at the behest of consumerism. He argues that this shift in technology has fundamentally shaped our epistemology, and it is almost impossible to comprehend anything outside the technological enframing of knowledge. The exception is when something breaks down, and the fault ‘shows up’ in fresh ways. Stiegler has several important addendums to Heidegger’s thesis. (...) Firstly, that Heidegger fails to fully appreciate the early Greek myth of Prometheus, and the technological depth that fire offers all human societies. Secondly, the fall, or failure, which is doubled in the myth of Prometheus, and shows up in epistemology accordingly. Thirdly the acceleration of technology since the onset of Information Technology, and the way this is disorientating our Being. I argue the fall in both Heidegger and early Stiegler has encaptured their imagination. In later work, Stiegler argues that acceleration is fused with algorithmic pretensions, that are distorting and undermining the creative political imaginary, and making it difficult to revalue the values that underpin the nihilist Anthropocene. The overcoming of the Anthropocene engages politics, economics, power, physics, and ecology. (shrink)

Austrian immigration authorities frequently reject the family reunion applications of immigrant workers. They justify their decisions not only on legal grounds but also on the basis of their own often prejudiced judgements of the applicants' ability to `integrate' into Austrian society. A discourse-historical method is combined with systemic-functionally oriented methods of text analysis to study the official letters which notify immigrant workers of the rejection of their family reunion applications. The systemic-functionally oriented methods are used in a detailed analysis of (...) a sample of rejection letters while the discourse-historical method allows this analysis to be intertextually connected to other related genres of discourse and strategies of argumentation, and to the history of post-war immigration in Austria generally.

This paper takes a sideways look at the controversial topic of educational assessment, raising the question: what place should the success/failure distinction have in an effective and humane educational system? Though the experience of failure may undermine the self-esteem that is conducive to learning, its possibility is clearly important educationally. Instead of asking whether teachers should be truthful about children’s achievements or dishonestly promote their self-esteem, we need to recognise a certain logical indeterminacy about what young children can do. Given (...) this, it is reasonable to presume in favour of many of their capacities rather than against them, for this is how children develop the confidence to act. This includes the confidence to fail as well as the confidence to succeed. It is argued that both are crucial for learning. (shrink)

Understanding climate change is becoming an urgent requirement for those in education. The normative values of education have long been closely aligned with the global, modernised world. The industrial model has underpinned the hidden and overt curriculum. Increasingly though, a new eco-centric orientation to economics, technology, and social organisation is beginning to shape up the post-carbon world. Unless education is up to date with the issues of climate change, the estate of education will be unable to meet its task of (...) knowledge transfer. This paper covers the basic science and ethical policy debates, and begins to outline the questions that will necessarily entangle education as we orientate ourselves to the new world that is upon us.

Happiness is a large idea. It looms enticingly before us when we are young, delivers verdicts on our lives when we are old, and seems to inform a responsible engagement with children. The question is raised: do we want this idea? I explore a distinction between rich and poor conceptions of happiness, suggesting that many sceptical arguments are directed against the latter. If happiness is to receive its teleological due, recognised in rather the way Aristotle saw it, as a final (...) end that crucially lacks specificity, it must be richly conceived without denying the significance of unhappiness or despair. I suggest that Aristotle's Nicomachean Ethics is ‘completed’ in a distinctively Aristotelian sense by authors like George Eliot and Virginia Woolf. Substantial excerpts are discussed to show how ideas like ‘making others happy’ may be richly conceived. By treating literary examples (poetically articulated, sensually received) as ineliminable reference points in our thinking, we open up a new way of imagining relationships in education. We attend communally, conversationally and often argumentatively to the dramas of human life. This, I argue, is how we grapple with large ideas and bring about ethical learning. (shrink)

In _Feminist Interpretations of John Rawls_, Ruth Abbey collects eight essays responding to the work of John Rawls from a feminist perspective. An impressive introduction by the editor provides a chronological overview of English-language feminist engagements with Rawls from his Theory of Justice onwards. She surveys the range of issues canvassed by feminist readers of Rawls, as well as critics’ wide disagreement about the value of Rawls’s corpus for feminist purposes. The eight essays that follow testify to the continuing (...) ambivalence among feminist readers of Rawls. From the perspectives of political theory and moral, social, and political philosophy, the essayists address particular aspects of Rawls’s work and apply it to a variety of worldly practices relating to gender inequality and the family, to the construction of disability, to justice in everyday relationships, and to human rights on an international level. The overall effect is to give a sense of the broad spectrum of possible feminist critical responses to Rawls, ranging from rejection to adoption. Aside from the editor, the contributors are Amy R. Baehr, Eileen Hunt Botting, Elizabeth Brake, Clare Chambers, Nancy J. Hirschmann, Anthony Simon Laden, Janice Richardson, and Lisa H. Schwartzman. (shrink)

A recent ontological modification of Cramer’s Transactional Interpretation, called “Possibilist Transactional Interpretation” or PTI, is extended to the relativistic domain. The present interpretation clarifies the concept of ‘absorption,’ which plays a crucial role in TI. In particular, in the relativistic domain, coupling amplitudes between fields are interpreted as amplitudes for the generation of confirmation waves by a potential absorber in response to offer waves, whereas in the nonrelativistic context CW are taken as generated with certainty. It is pointed out that (...) solving the measurement problem requires venturing into the relativistic domain in which emissions and absorptions take place; nonrelativistic quantum mechanics only applies to quanta considered as ‘already in existence’, and therefore cannot fully account for the phenomenon of measurement, in which quanta are tied to sources and sinks.

In this paper I adduce a new argument in support of the claim that IBE is an autonomous form of inference, based on a familiar, yet surprisingly, under-discussed, problem for Hume’s theory of induction. I then use some insights thereby gleaned to argue for the claim that induction is really IBE, and draw some normative conclusions.

A large literature has grown up around the proposed use of 'weak measurements' to allegedly provide information about hidden ontological features of quantum systems. This paper attempts to clarify the fact that 'weak measurements' are simply strong measurements on one member of an entangled pair, and that all such measurements thus effect complete disentanglement of the pair. The only thing 'weak' about them is that the correlation established via the entanglement does not correspond to eigenstates of the 'weakly measured observable' (...) for the component system that is subject to the weak measurement. It is observed that complete disentanglement always occurs, whether post-­‐selection is performed before or after the pointer detection. Assertions in the literature that weak measurements leave a system negligibly disturbed are therefore inaccurate, and claims based on those assertions need to be critically reassessed. (shrink)

One of the virtues of the biosemantic view of language is the clarity and simplicity of its description of the general nature of nonrepresentational linguistic constructions. It doesn't follow, however, that it is obvious on this view how these functions should be described individually. After an explanation of the biosemantic approach, initial suggestions are made for analyses of a variety of nonrepresentational constructions that have traditionally been considered problematic. Included are “not”, “is” (of identity), “exists”, “means”, “but”, “if … then”, (...) “possibly” and “true.”. (shrink)

Tim Maudlin's argument for the inconsistency of Cramer's Transactional Interpretation of quantum theory has been considered in some detail by Joseph Berkovitz, who has provided a possible solution to this challenge at the cost of a significant empirical lacuna on the part of TI. The present paper proposes an alternative solution in which Maudlin's charge of inconsistency is evaded but at no cost of empirical content on the part of TI. However, Maudlin's argument is taken as ruling out Cramer's heuristic (...) "pseudotime" explanation of the realization of one transaction out of many. (shrink)

In view of a resurgence of concern about the measurement problem, it is pointed out that the Relativistic Transactional Interpretation remedies issues previously considered as drawbacks or refutations of the original TI. Specifically, once one takes into account relativistic processes that are not representable at the non-relativistic level, absorption is quantitatively defined in unambiguous physical terms. RTI therefore provides a well-defined terminus to what appears to be a necessary infinite regress concerning ‘absorption’ when only the non-relativistic level is considered. In (...) addition, specifics of the relativistic transactional model demonstrate that the Maudlin ‘contingent absorber’ challenge to the original TI cannot even be mounted: basic features of established relativistic field theories dictate that the ‘slow-moving offer wave’ required for the challenge scenario cannot exist. It is concluded that issues previously considered obstacles for TI are no longer legitimately viewed as such, and that reconsideration of the transactional picture is warranted in connection with solving the measurement problem.

Do we really know the things we think we know? Are any of our beliefs reasonable? Scepticism gives a pessimistic reply to these important epistemological questions - we don't know anything; none of our beliefs are reasonable. But can such a seemingly paradoxical claim be more than an intellectual curiousity? And if it is, can it be refuted? Ruth Weintraub answers yes to both these questions. The sceptical challenge is a formidable one, and should be confronted, not dismissed. The (...) theoretical and practical difficulties it presents - in that the sceptical life cannot be lived, and the doctrine seems self-defeating - are in fact superficial, according to Ruth Weintraub. Her study looks at the sceptical arguments of Descartes, Hume and the ancient Greek sceptic, Sextus Empiricus. The author argues that by drawing on philosophy, rather than science, the sceptical challenge can be answered. _The Sceptical Challenge_ is a bold and original response to scepticism; it represents a new way of looking at the field for philosophers of epistemology.

ABSTRACTComparative effectiveness studies, referred to here as “usual-care” trials, seek to compare current medical practices for the same medical condition. Such studies are presumed to be safe and involve only minimal risks. However, that presumption may be flawed if the trial design contains “unusual” care, resulting in potential risks to subjects and inaccurately informed consent. Three case studies described here did not rely on clinical evidence to ascertain contemporaneous practice. As a result, the investigators drew inaccurate conclusions, misinformed research participants, (...) and subjects’ safety was compromised. Before approving usual-care protocols, IRBs and scientific review committees should evaluate the quality and completeness of information documenting usual-care practices. Guidance from governmental oversight agencies regarding evidence-based documentation of current clinical practice could prevent similar occurrences in future usual-care trials. Accurate information is necessary to ensure that trials comply with government regulations that require minimizing research risks to subjects and accurate informed consent documents. (shrink)

This volume contains essays which cover a range of aspects in the debate over genetic testing. It looks at both the advantages and disadvantages involved in knowing or not knowing whether one is a carrier of certain genetic traits.

The 'enhancement agenda' in educational policy is based on the idea that 'something affective', which supports and improves learning, can be a) measured and b) enhanced. This idea is explored, and it is argued that the identity of the 'something' that the enhancement agenda seeks to enhance is fatally obscure, as is the idea of measurable enhancement. Interpreted in Aristotelian terms as the desire to cultivate certain emotional dispositions, the idea of 'prevailing' on children morally makes good sense. Unlike the (...) enhancement agenda, however, the Aristotelian project is informal, intimate and bound to the notion of human flourishing. The paper concludes with an enquiry into the central concerns that drive the enhancement debate, and an answer is sketched in terms of excessive fear and shame, and the circular logic of failure. This answer, it is argued, elucidates an 'ordinary' concept of low self-esteem that is a potential 'barrier to learning', and should therefore be taken seriously by educators. (shrink)

The universalist argument that all children should be educated in inclusive mainstream schools, irrespective of their difficulties or disabilities, is traced to the claims that special schools and disability ‘labels’ are inherently humiliating, and that no decent society tolerates inherently humiliating institutions. I ask whether there is a sound reason for a child to feel humiliated by special schools/disability ‘labels’ as such, and find none. Empirically, some do and some do not find these humiliating, and it is argued that the (...) failure to address the multiple ‘realities’ of disability and learning difficulty is responsible for the policy impasse in this area.

Rhodes seeks to defend her ‘conclusion that everyday ethics and medical ethics [are] incompatible’.1 She challenges ‘views that medical ethics is nothing more than common morality applied to clinical matters’.1 Beauchamp and Childress explicate the term ‘common morality’ at length.2 Nowhere do they claim that medical ethics is ‘nothing more than common morality applied to clinical matters’. Here is what they do say: “The origin of the norms of the common morality is no different in principle from the origin of (...) the norms of a particular morality for a medical or other profession … The primary difference is that the common morality has authority in all communities, whereas particular moralities are authoritative only for specific groups”.2 This critique discusses the seven examples Rhodes uses to illustrate her main point: that common morality and medical ethics are radically different. I contend that common morality accounts for the purported differences she cites. In ordinary life, people can simply mind their own business, whereas physicians have a duty to act in their professional setting. On this view, common morality cannot explain the moral obligation people have to prevent easily avoidable harm to others. A bystander …. (shrink)

A relation is obtained between weak values of quantum observables and the consistency criterion for histories of quantum events. It is shown that “strange” weak values for projection operators always correspond to inconsistent families of histories. It is argued that using the ABL rule to obtain probabilities for counterfactual measurements corresponding to those strange weak values gives inconsistent results. This problem is shown to be remedied by using the conditional weight, or pseudo-probability, obtained from the multiple-time application of Lüders’ Rule. (...) It is argued that an assumption of reverse causality implies that weak values obtain, in a restricted sense, at the time of the weak measurement as well as at the time of post-selection. Finally, it is argued that weak values are more appropriately characterized as multiple-time amplitudes than expectation values, and as such can have little to say about counterfactual questions.

Recently, some of the leading proponents of the view that there is widespread incommensurability among goods have suggested that the incommensurability of some goods is a constitutive feature of the goods themselves. So, for example, a friendship and a million dollars are incommensurable because it is part of what it is to be a friendship that it be incommensurable with money. According to these ‘constitutive incommensurabilists’ incommensurability follows from the very nature of certain goods. In this paper, I examine this (...) idea and argue that constitutive incommensurabilists have mistaken for constitutive incommensurability a particular emphatic kind of comparability. This examination involves an account of ‘higher’ and ‘lower’ goods and an explanation of how goods of different ‘types’ figure in practical conflict. (shrink)

This paper is not concerned with the (amply discussed) question as to the rational response to peer disagreement. Instead, it addresses a (considerably less often debated) problem to which many views about the (epistemic) significance of disagreement are vulnerable (to some extent or another): self-undermining. I reject several answers that have been proposed in the literature, defend one that has been offered (by meeting objections to it), and show that in its light, the prevalent assumption that the ‘equal-weight view’, a (...) prominent view about disagreement, rationally requires us to suspend judgement about contentious matters, is seen to be too pessimistic.

Teachers need grounded ethical confidence: an intellectual virtue analogous to courage. I distinguish this from SCAA's notion of teacher confidence, based on the ‘authority of consensus’. Such a notion is challenged by Wittgenstein's later philosophy. I argue that confidence in authority is deferential rather than intellectual, which is not what we want for teachers. As courage (according to Aristotle) is a mean between vices, grounded ethical confidence is a mean between tendencies to excessive and insufficient doubt (forms of ‘not knowing (...) one's way about’ philosophically.) It is the virtue of thinking well ethically, and knowing that one thinks well. (shrink)

This paper is an empirical critique of causal accounts of scientific explanation. Drawing on explanations which rely on nonlinear dynamical modeling, I argue that the requirement of causal relevance is both too strong and too weak to be constitutive of scientific explanation. In addition, causal accounts obscure how the process of mathematical modeling produces explanatory information. I advance three arguments for the inadequacy of causal accounts. First, I argue that explanatorily relevant information is not always information about causes, even in (...) cases where the explanandum has an identifiable causal history. Second, I argue that treating theoretical explanations as reductions from general causal laws does not accurately describe the types of "top-down" explanations typical of dynamical modeling. Finally, I argue that causal/mechanical accounts of explanation are intrinsically vulnerable to the irrelevance problem. (shrink)

The criteria for determining what it is to do good medical ethics are the quality of ethical analysis and ethical justifications for decisions and actions. Justifications for decisions and actions rely on ethical principles, be they the ‘famous four’ or subsidiary ethical principles relevant to specific contexts. Examples from clinical ethics, research ethics and public health ethics reveal that even when not stated explicitly, principles are involved in ethical justifications. Principles may come into conflict, however, and the resolution of an (...) ethical dilemma requires providing good reasons for preferring one principle over another. (shrink)

The book brings together social philosophy and educational theory. Liberalism's unresolved tensions between freedom and equality, public and private good, individual and state, etc., are illuminated by controversies in educational theory and policy.

It is pointed out that a slight variation on the Wheeler Delayed Choice Experiment presents the same challenge to orthodox quantum mechanics as Maudlin-type contingent absorber experiments present to the Transactional Interpretation. Therefore, the latter cannot be used as a basis for refutation of TI.

ABSTRACT: Simon Baron-Cohen has argued that autism and related developmental disorders (sometimes called “autism spectrum conditions” or “autism spectrum disorders”) can be usefully thought of as the condition of possessing an “extreme male brain.” The impetus for regarding autism spectrum disorders (ASD) this way has been the accepted science regarding the etiology of autism, as developed over that past several decades. Three important features of this etiology ground the Extreme Male Brain theory. First, ASD is disproportionately male (approximately 10:1 in (...) the case of Asperger’s Syndrome or high-functioning autism (HFA) and approximately 4:1 in the case of autistic disorder). Second, ASD is not psychogenic but biological in origin, and hence is not the product of sexist conditioning or childrearing practices, although these may affect the development of the disorder. Third, ASD is regarded as a spectrum developmental disorder, unlike other disorders such as Down Syndrome that are diagnosed by a (nearly) binary criterion. Down Syndrome, for example, is diagnosed by the presence in all or most cells within a given individual of an extra copy of Chromosome 21. Autism, on the other hand, is diagnosed by the presence of a set of symptoms that vary in their intensity and in their milder forms seem to conform to purported sex differences in cognitive, emotional, and social functioning. -/- In this paper, I do not challenge accepted science regarding the etiology of autism, and I do not challenge the idea of ASD as a disorder. Nor do I wish to offer an alternative account of what autism is. Instead, I focus on the usefulness of thinking of a disorder as an extreme version of ordinary sex differences. Does it follow from the fact that a disorder is more often found in men that we should think of it as an extreme form of maleness? If not, what other conditions must be met in order to warrant this way of thinking about ASD? What does it mean to say that ASD is a form of “extreme male brain”? Feminists are rightly skeptical of theories that make claims about male and female brains, so how should we respond to the clear evidence that the differences between typical and ASD individuals are not caused by childrearing practices? I explain what I take to be Baron-Cohen’s central argument that autism should be seen as the extreme male brain, and critique that argument. I conclude that there is no good argument that autistic symptoms should be regarded as an extreme form of male mental traits, and that Baron-Cohen’s claim does not help us to understand autism, women, or men. His claim is a speculative thesis that is readily mobilized for sexist practices. As such it requires a higher threshold for evidentiary support and rigorous argumentation—support and argumentation that does not exist. -/- KEYWORDS: autism, brain, gender, neuroscience, feminism, male .

In exploring the concept of vulnerability, we do not begin with a blank slate. In research involving human subjects, ethics guidelines typically provide a rough definition of the concept. For example, the commentary on Guideline 13 in the International Ethical Guidelines for Biomedical Research Involving Human Subjects, issued by the Council for International Organizations of Medical Sciences (CIOMS), says that "vulnerable persons are those who are relatively (or absolutely) incapable of protecting their own interests. More formally, they may have insufficient (...) power, intelligence, education, resources, strength, or other needed attributes to protect their own interests" (CIOMS 2002).

Citizenship and its education is again gaining importance in many countries. This paper uses England as its primary example to develop a Habermasian perspective on this issue. The statutory requirements for citizenship education in England imply that significant attention be given to the moral and social development of the learner over time, to the active engagement of the learner in community and to the knowledge skills and understanding necessary for political action. This paper sets out a theoretical framework that offers (...) a perspective on learning suitable for these far-reaching aims. We argue that schools need to shift from the currently dominant discourse of accountability to incorporate a discourse of care in order to make room for an effective and appropriate pedagogy for citizenship. Habermas’s social theory gives us a theoretical framework that properly locates schools within the lifeworld as part of civil society. Schools should therefore attend to hermeneutical and emancipatory concerns, not only to strategic interests. We put these in the context of Habermas’s social theory to paint an alternative vision learning for citizenship education which is based in developing the dispositions, values and attitudes necessary for lifelong learning with a view to developing ongoing communicative action.

Commercial video games are popular entertainment media and part of students’ media reality. While commercial video games’ main purpose is not learning, they nonetheless could and should serve as objects of reflection in formal educational settings. Teachers could guide student learning and reflection as well as motivate students with commercial video games, but more evidence from formal educational settings is required. We conducted two mixed methods case studies to investigate students’ reflection processes using commercial video games in regular formal high (...) school teaching. In a double lesson, 29 students of a 10th-grade biology course and 17 students of a 12th-grade advanced course on history played and discussed a commercial video game related to the current curricular topic. We examined the reflection processes of students in terms of their reactions to the teachers’ game-related statements and questions. Regarding teachers’ statements, students discussed several topics related to game enjoyment and the games’ representation of topic-related content. Regarding teachers’ questions, students discussed multiple goals in each game, how the games represented topic-related content, and how the games could be appropriate for learning. In Study 2, students additionally discussed emotions, stereotypes, violence, and the narrative related to the digital history game. We found that the discussions provided students opportunities to reflect on their game experiences and the current curricular topic as well as to practice media criticism. We further provide quantitative results on students’ perceived topic knowledge, on several facets of their learning motivation, and on their acceptance of video games. Overall, our findings illustrate the educational value of using commercial video games as objects of reflection. (shrink)

Testing is an effective learning method, and it is the basis of mobile quiz apps. Quiz apps have the potential to facilitate remote and self-regulated learning. In this context, automatized feedback plays a crucial role. In two experimental studies, we examined the effects of two feedback types of quiz apps on performance, namely, the standard corrective feedback of quiz apps and a feedback that incorporates additional information related to the correct response option. We realized a controlled lab setting (n= 68, (...) Study 1) and an unsupervised mobile setting (n= 150, Study 2). In the learning phase, participants used the quiz app and received feedback. They also completed a subsequent test as well as a follow-up test 1 week later by using the same quiz app. Irrespective of feedback type and setting, cognitive outcomes (quiz scores) and metacognitive outcomes (response certainty) increased similarly in the short term and long term. Feedback effects were not moderated by participants' overall response certainty during learning, their prior knowledge, and the difficulty of quiz items. Moreover, we found that participants perceived the quiz app to be similarly attractive, interesting, and enjoyable in both feedback conditions and that they spent slightly more time to process quiz items in the lab setting. We discuss these results in detail, including the role of moderating and mediating factors and prospects for further research and practice. Overall, our results underline that quiz apps are useful and effective tools that can support the acquisition and retention of semantic knowledge in different learning settings. (shrink)

Time-symmetric interpretations of quantum theory are often presented as featuring "retrocausal" effects in addition to the usual forward notion of causation. This paper examines the ontological implications of certain time- symmetric theories, and finds that no dynamical notion of causation applies to them, either forward or backward. It is concluded that such theories actually describe a static picture, in which the notion of causation is relegated to a descriptor of static relationships among events. In addition, these theories lead to an (...) epistemic rather than ontologically referring, realist view of quantum states. (shrink)
