Medical microbiology presents a challenge to undergraduate students, mostly due to its extensive content and complexity of unfamiliar terminology. In addition to a narrative review of the literature, we report findings on students’ motivation for and approach to learning in the Infections module of an undergraduate medical curriculum, and their perceived lack of retention of knowledge acquired in the module, as determined by a self-administered, anonymous questionnaire. When students experienced information overload, they reverted to performance goals and the wrong motivation for learning. Their focus turned primarily to being successful in tests and examinations, and they consequently adopted a surface approach to learning. Surface learning and memorisation of facts without understanding its content usually result in moderate retention of knowledge, which could handicap the development of clinical reasoning. However, the concern about students’ perceived poor retention of knowledge can be laid to rest – the prognosis is not discouraging after all.  相似文献

Visual field biases have been identified as markers of atypical lateralization in children with developmental conditions, but this is the first investigation to consider early lateralized gaze behaviors for social stimuli in preterm infants. Eye-tracking methods with 51 preterm (33 male, 92.1% White) and 61 term-born (31 male, 90.1% White) infants aged 8–10 months from Edinburgh, UK, captured the development of visual field biases, comparing gaze behavior to social and non-social stimuli on the left versus right of the screen. Preterm infants showed a significantly reduced interest to social stimuli on the left versus right compared to term children (d = .58). Preterm children exhibit early differential orienting preferences that may be an early indicator of atypical lateralized function.  相似文献

Existing scholarship on the debates over expertise in mid-nineteenth-century Britain has demonstrated the importance of popular writings on the sciences to definitions of scientific authority. Yet while men of science might position themselves in opposition to the stereotype of the merely popular writer, the self-identity of the popular writer remained ambiguous. This essay examines the careers of William Charles Linnaeus Martin (1798-1864) and Thomas Milner (1808-ca. 1883) and places them in the context of others who made their living by writing works on the sciences for the general reader. Martin wrote on zoology and Milner moved between astronomy, geology, and geography. The essay unravels the close but ambivalent relationship between the professions of authorship and of science and highlights writing as another aspect of scientific practice. Both writers were moderately financially successful, but Martin's sense of failure and Milner's satisfaction reflect their contrasting images of their professional identity.  相似文献

This study examined whether practice with arithmetic problems presented in a nontraditional problem format improves understanding of mathematical equivalence. Children (M age = 8;0; N = 90) were randomly assigned to practice addition in one of three conditions: (a) traditional, in which problems were presented in the traditional "operations on left side" format (e.g., 9 + 8 = 17); (b) nontraditional, in which problems were presented in a nontraditional format (e.g., 17 = 9 + 8); or (c) no extra practice. Children developed a better understanding of mathematical equivalence after receiving nontraditional practice than after receiving traditional practice or no extra practice. Results suggest that minor differences in early input can yield substantial differences in children's understanding of fundamental concepts.  相似文献

Previous studies have found that social exclusion can cause distress to those excluded. One method used to study social exclusion is through a virtual ball-toss game known as Cyberball. In this game, participants may be excluded from or included in the ball-toss game and typically report lower feelings of self-esteem, control, belonging, and meaningful existence following exclusion. Experiments 1 and 2 sought to explore the transfer of feelings of exclusion and inclusion through stimulus equivalence classes. In both experiments, participants were trained to form two three-member equivalence classes (e.g., A1–B1, B1–C1; A2–B2, B2–C2) and were tested with novel stimulus combinations (A1–C1, C1–A1, A2–C2, C2–A2). Thereafter, participants were exposed to the Cyberball exclusion and inclusion games. In these games, one stimulus (C1) from one equivalence class was assigned as the Cyberball inclusion game name, whereas one stimulus (C2) from the other equivalence class was assigned as the Cyberball exclusion game name. In Experiment 2, participants were only exposed to the Cyberball exclusion game. During a subsequent transfer test, participants were asked to rate how included in or excluded from they thought they would be in other online games, corresponding to members of both equivalence classes. Participant reported that they felt they would be excluded from online games if the games were members of the same equivalence class as C2. In contrast, participants reported that they felt they would be included in online games if the games were members of the same equivalence class as C1. Results indicated the transfer of feelings of inclusion (Experiment 1) and feelings of exclusion (Experiments 1 and 2) through equivalence classes.  相似文献

This paper provides a systematic examination of the use of a Grand Innovation Prize (GIP) in action – the Progressive Automotive Insurance X PRIZE – a $10 million prize for a highly efficient vehicle. Following a mechanism design approach we define three key dimensions for GIP evaluation: objectives, design, and performance, where prize design includes ex ante specifications, ex ante incentives, qualification rules, and award governance. Within this framework we compare observations of GIPs from three domains – empirical reality, theory, and policy – to better understand their function as an incentive mechanism for encouraging new solutions to large-scale social challenges. Combining data from direct observation, personal interviews, and surveys, together with analysis of extant theory and policy documents on GIPs, our results highlight three points of divergence: first, over the complexity of defining prize specifications; secondly, over the nature and role of incentives, particularly patents; thirdly, the overlooked challenges associated with prize governance. Our approach identifies a clear roadmap for future theory and policy around GIPs.  相似文献

We suggest that most inquiry in special education is misconceived. We examine the consequences of an allegiance to the erstwhile knowledge of special education in professional assumptions about learning difficulty and the research and practice of special education. We assert that obeisance to that knowledge has proven unfruitful for the children and young people it is intended to serve. Suggesting that the preferred inquiry methods of special education have led only into culs-de-sac, we argue that inclusive education should reinstate the importance of teachers' own experience, insights, and values—restore the significance of reflective practice. It is these that should provide the lead for new developments in inclusion. We suggest that arguments for inclusion have to emerge less out of the kind of supposed knowledge so respected by 20th-century educators—less out of notions of success and failure (of children or of schools)—and more out of ideas about social justice and human rights.  相似文献

This investigation assessed the effect of dietary nitrate (NO3?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO2peak 53.1 ± 8.7 mL.kg?1.min?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYPBR; 13 mmol NO3?) or NO3depleted BR placebo (HYPPLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO2) was measured during the warm-up. There were no significant differences observed between HYPBR and HYPPLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYPBR compared with HYPPLA. There was a moderate effect for VO2 to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO3? may not improve repeat-sprint performance in hypoxia but may reduce VO2 during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献
