Performative technologies and teacher subjectivities: A conceptual framework

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS).     

Teaching Traditions in Science Teachers’ Practices and the Introduction of National Testing

Our main interest in this article is to explore whether Swedish teachers changed their teaching and assessment practices in relation to the new national tests in science education that were introduced 2009. Data was collected using a web-distributed questionnaire, which was answered by 407 teachers. The concept of teaching traditions is used to capture patterns of what is emphasized by teachers in terms of goals and content in teaching and the design of the questionnaire was based on the concept of curriculum emphases. The results show two distinct groups of focus, which are compared with two traditions within science education: the Academic and the Moral tradition. The main content where teaching has been changed is in making science more applied than before, where applied not only means the application of science knowledge to practical technical issues, but also to moral and political issues.     

Leg amputation side determines performance in curve sprinting: a case study on a Paralympic medalist

The lower limb kinetics of curve sprinting in amputees are not well described in the literature, particularly with respect to the effect of the side of amputation. This is an issue due to the importance of the knowledge for prosthetic design and classification of athletes. Thus, the aim of this study was to investigate the influence of side of amputation on curve sprinting performance in athletes with a unilateral leg amputation. A three-dimensional motion analysis system (Vicon), four force plates (Kistler) and a modified mathematical human model (ALASKA) were used to compare clockwise and counter clockwise curve sprinting lower limb kinematics and kinetics of a Paralympic medalist with a left-sided knee exarticular amputation. Results reveal that vertical ground reaction force application and total vertical impulse were lower when the affected limb was at the inside of the curve. The unaffected limb showed joint mechanics different to those established for non-amputee athletes and might contribute better to propulsion when being the inside limb. Curve sprinting biomechanics and the ability to attain high radial velocities are directly dependent on the side of amputation relative to the curve direction in a unilateral amputee athlete of highest performance level.     

Energy turnover during 24 hours and 6 days of adventure racing

Abstract

Energy turnover was assessed in two conditions of mixed ultra-endurance exercise. In Study 1, energy expenditure and intake were measured in nine males in a laboratory over 24 h. In Study 2, energy expenditure was assessed in six males during an 800-km Adventure race (mean race time 152.5 h). Individual correlations between heart rate and oxygen uptake ([Vdot]O₂) were established during pre-tests when kayaking, cycling, and running. During exercise, energy expenditure was estimated from continuous heart rate recordings. Heart rate and [Vdot]O₂ were measured regularly during fixed cycling work rates to correct energy expenditure for drift in oxygen pulse. Mean energy expenditure was 18,050 ± 2,390 kcal (750 ± 100 kcal · h^?1) and 80,000 ± 18,000 kcal (500 ± 100 kcal · h^?1) in Study 1 and Study 2 respectively, which is higher than previously reported. Energy intake in Study 1 was 8,450 ± 1,160 kcal, resulting in an energy deficit of 9,590 ± 770 kcal. Body mass decreased in Study 1 (?2.3 ± 0.8 kg) but was unchanged in Study 2. Fat mass decreased in Study 2 (?2.3 ± 1.5 kg). In Study 1, muscle glycogen content decreased by only 60%. Adventure racing requires a high energy expenditure, with large inter-individual variation. A large energy deficit is caused by inadequate energy intake, possibly due to suppressed appetite and gastrointestinal problems. The oxygen pulse, comparing start to 12 h of exercise and beyond, increased by 10% and 5% in Study 1 and Study 2 respectively. Hence, estimations of energy expenditure from heart rate recordings should be corrected according to this drift.     

Education for Epiphany: The Case of Plato's Lysis

While a great deal has been written on Plato's Lysis in philosophy and philology journals over the last thirty years, nothing has been published on Lysis in the major Anglo‐American philosophy of education journals during that time. Nevertheless, this dialogue deserves attention from educators. In this essay, Mark Jonas argues that Lysis can serve as a model for educators who want to move their students beyond mere aporia, but also do not want to dictate answers to students. Although the dialogue ends in Socrates's affirmation of aporia, his affirmation is actually meant to persuade his interlocutors to reflect on an epiphany they had previously experienced. In what follows, Jonas offers a close reading of relevant passages of Lysis, demonstrating the way that Socrates leads his interlocutors to an epiphany without forcing his answers upon them.     

Three Misunderstandings of Plato's Theory of Moral Education

In this essay, Mark Jonas argues that there are three broadly held misconceptions of Plato's philosophy that work against his relevance for contemporary moral education. The first is that he is an intellectualist who is concerned only with the cognitive aspect of moral development and does not sufficiently emphasize the affective and conative aspects; the second is that he is an elitist who believes that only philosopher‐kings can attain true knowledge of virtue and it is they who should govern society; the third is that he affirms the realm of the Forms as a literal metaphysical reality and believes that for individuals to attain virtue they must access this realm through contemplation. The goal of this essay is to correct these misconceptions. The rehabilitation of Plato's reputation may enable future researchers in moral education to discover in his philosophy new avenues for exploring how best to cultivate virtues in students.     

Laboratory medicine education in Lithuania

In Lithuania there are two types of specialists working in medical laboratories and having a university degree: laboratory medicine physicians and medical biologists. Both types of specialists are officially being recognized and regulated by the Ministry of Health of Lithuania. Laboratory medicine physicians become specialists in laboratory medicine after an accredited 4-year multidisciplinary residency study program in Laboratory Medicine. The residency program curriculum for laboratory medicine physicians is presented. On December 9, 2009 the Equivalence of Standards for medical specialists was accepted and Lithuanian medical specialists in Clinical Chemistry and Laboratory Medicine can now apply for EC4 registration. Medical biologists become specialists in laboratory medicine after an accredited 2-year master degree multidisciplinary study program in Medical Biology, consisting of 80 credits. Various postgraduate advanced training courses for the continuous education of specialists in laboratory medicine were first introduced in 1966. Today it covers 1-2-week courses in different subspecialties of laboratory medicine. They are obligatory for laboratory medicine physicians for the renewal of their license. It is not compulsory for medical biologists to participate in these courses. The Centre of Laboratory Diagnostics represents a place for the synthesis and application of the basic sciences, the performance of research in various fields of laboratory medicine, as well as performance of thousands of procedures daily and provision of specific teaching programs.
