“Shut up and calculate”: the available discursive positions in quantum physics courses

Educating new generations of physicists is often seen as a matter of attracting good students, teaching them physics and making sure that they stay at the university. Sometimes, questions are also raised about what could be done to increase diversity in recruitment. Using a discursive perspective, in this study of three introductory quantum physics courses at two Swedish universities, we instead ask what it means to become a physicist, and whether certain ways of becoming a physicist and doing physics is privileged in this process. Asking the question of what discursive positions are made accessible to students, we use observations of lectures and problem solving sessions together with interviews with students to characterize the discourse in the courses. Many students seem to have high expectations for the quantum physics course and generally express that they appreciate the course more than other courses. Nevertheless, our analysis shows that the ways of being a “good quantum physics student” are limited by the dominating focus on calculating quantum physics in the courses. We argue that this could have negative consequences both for the education of future physicists and the discipline of physics itself, in that it may reproduce an instrumental “shut up and calculate”-culture of physics, as well as an elitist physics education. Additionally, many students who take the courses are not future physicists, and the limitation of discursive positions may also affect these students significantly.     

A Review of Practical Reasoning in Child and Youth Research

The purpose of the review is to investigate various relations between the concepts of competence and participation found within child and youth research with the aim of identifying differences in practical reasoning of the various kinds of child research. The search identified 260 articles, and an in-depth analysis of 39 articles was conducted, elaborating the conceptual differences inherent in the different child research fields. Based on a philosophy of practice, the analysis identified 3 different causal connections between the concepts of competence and participation, indicating 3 different ways of understanding means and ends in child research. The review thereby offers an understanding of how and why interdisciplinary problems sometimes occur in education and child care.     

Tweeting the Viewer—Use of Twitter in a Talk Show Context

Twitter is currently one of the most popular outlets of so-called social media, Internet services that allow their users to communicate and share content in a variety of ways. As with the Internet itself, Twitter has been heralded to hold interesting possibilities within the context of journalism—potentially bringing journalists and their respective audiences closer to each other through supposedly common Twitter practices like @ messages and retweeting. This article presents a large-scale empirical study on Twitter use in the journalistic context. The aim is to assess patterns of journalist-audience interaction on Twitter. Specifically, the article outlines a structural analysis of Twitter use pertaining to the first season of the current events talk show Hübinette, which aired on Swedish public service television during the fall of 2011. Employing state-of-the-art approaches for data collection and analysis, the article shows that while traditional patterns of journalist-reader relationships are most common, some users are employing the Twitter platform in somewhat unforeseen ways.     

The role of schools in explaining individuals’ subject choices at age 14

Abstract

The subjects that young people study from age 14 onwards may have important consequences for their future academic and labour market outcomes. These decisions are shaped by the schools in which they find themselves. Schools also face constraints of their own. This paper explores the extent to which individuals’ decisions are affected by the school they attend and to what extent this is affected by the composition of schools in terms of academic attainment, gender, and socioeconomic background. We use multi-level variance decomposition models applied to administrative data on the subjects that young people in mainstream state-funded schools in England study between ages 14 and 16. Our results highlight the important role that constraints on schools play in subject choice decisions. We also note the particular role of attending a non-selective school within a selective schooling district.     

The influence of child,family, home factors and pre‐school education on the identification of special educational needs at age 10

The early identification of young children's special educational needs (SEN), as well as the development of specific strategies to support those children identified with special needs, are increasingly recognised as crucial to facilitating good adjustment to school and to ensuring that such children are helped to reach their full potential in education. Using a large national sample of young children in England whose developmental progress was followed up from pre‐school, this study investigates which child, family, home and pre‐school factors can be viewed as risk or protective factors for later SEN‐status at age 10. The experience of high‐quality pre‐school education is shown to reduce the likelihood of a child being identified as experiencing SEN in the long run. Teachers’ assessments of SEN are found to be strongly related to children's reading and mathematics attainment, but other factors also predict SEN, including a child's age within a year group.     

The Scientific Study of Expert Levels of Performance: general implications for optimal learning and creativity 1

Recent research in many different domains of expertise has shown that the large differences in performance between experts and novices are frequently reproducible under standardized conditions and can often be captured with representative tasks in the laboratory. Furthermore, these differences in performance are predominantly mediated by complex skills acquired over a decade, as a result of high daily levels of activities which are specially designed'to improve performance (deliberate practice). The effects of extended deliberate practice are remarkably far‐reaching and include physiological adaptations and qualitative changes in performance mediated by acquired cognitive skills. Most importantly, expert performers have acquired mental representations that allow them to plan and reason about potential courses of action and these representations also allow experts to monitor their performance, thus providing critical feedback for continued complex learning. The study of elite performance also reveals how acquired representation and skills provide the necessary tools for the ultimate eminent achievement, namely the generation of creative innovations to the domain.

     

Managing the teaching–research nexus: ideals and practice in research-oriented universities

This paper demonstrates that while ideals of close linkages between research and teaching are widely embraced in research-oriented universities, a practice of division of labour between teaching-oriented and research-oriented staff persists. In an investigation of how the research–teaching nexus is managed at three Swedish universities, we identify a perceived misalignment between institutional incentives for individual academic staff and the needs of teaching. Under pressure from such tensions, managers are forced to deploy pragmatic strategies for the staffing of undergraduate education tasks. This includes allowing research needs and agendas to take priority over teaching needs. While managers seek to secure the participation of senior researchers in education, they often actively prefer to delegate the bulk of teaching activities to less research-active staff. Such strategies seem to reinforce existing patterns of division of labour among academic staff.     

Critical perspectives on Danish early childhood education and care: between the technical and the political

This paper discusses trends in contemporary Danish early childhood education and care (ECEC). Data are sourced from various policy documents, along with material from ongoing research projects in which the authors are involved. It is claimed that contemporary policy on Danish day care services has a tendency to emphasize narrow curriculum improvements and standardized testing. The democratic dimensions are still relatively strong, but at the moment these dimensions are interpreted within a skills‐and‐testing framework, which is leading to a situation where the political masquerades as the technical.     

Graphical means for inspecting qualitative models of system behaviour

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios. Given a library of model fragments and a scenario describing an initial situation, the qualitative simulation engine generates predictions in the form of a state–transition graph. This rich knowledge representation has potential for educational purposes. However, communicating the contents of simulation models effectively to learners is not trivial. The predicate logic format used by Garp is not easy for non-experts to understand, and a simulation often contains so much information that it is difficult to get an overview while still having access to detailed information. To address these problems, a tool has been developed that generates graphical representations of the information contained in a qualitative simulation. This tool, named VisiGarp, incorporates a vocabulary of graphical elements for model ingredients and relationships, and combines these into interactive diagrams. VisiGarp has been evaluated by thirty students, with promising results, using a setup which included simulation results and exercises about Brazilian Cerrado ecology.     

Anabolic–androgenic steroid use and correlates in Norwegian adolescents

This paper surveys the prevalence and correlates of anabolic androgenic steroids (AAS) use among Norwegian adolescents, and examines the degree to which sports participation is a mediating or moderating factor to well-known correlations between AAS use and problem behaviour. The data come from the “Ungdata” study, a cross-national youth survey system offered to all municipalities in Norway (response rate: 74%, N?=?77,572). The study demonstrates a lifetime prevalence of AAS use of 1.27% and a higher prevalence among boys (1.81%) than girls (0.76%). The analyses show that AAS use is clearly related to problem behaviour such as violence and other substance use. When controlling for problem behaviour, there are no correlations between AAS use and exercising in a sports club or on one’s own, whilst there is a weak positive correlation between AAS use and exercising in a gym or engaging in other forms of physical exercise such as dancing or martial arts. These patterns are more or less the same for boys and for girls. We conclude that adolescent AAS use is a low-prevalence phenomenon that primarily takes place in smaller subgroups of individuals who engage in other forms of problem behaviour as well.
