Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support. 相似文献

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months. 相似文献

Although molecular-level details are part of the upper-secondary biology curriculum in most countries, many studies report that students fail to connect molecular knowledge to phenomena at the level of cells, organs and organisms. Recent studies suggest that students lack a framework to reason about complex systems to make this connection. In this paper, we present a framework that could help students to reason back and forth between cells and molecules. It represents both the general type of explanation in molecular biology and the research strategies scientists use to find these explanations. We base this framework on recent work in the philosophy of science that characterizes explanations in molecular biology as mechanistic explanations. Mechanistic explanations describe a phenomenon in terms of the entities involved, the activities displayed and the way these entities and activities are organized. We conclude that to describe cellular phenomena scientists use entities and activities at multiple levels between cells and molecules. In molecular biological research, scientists use heuristics based on these intermediate levels to construct mechanistic explanations. They subdivide a cellular activity into hypothetical lower-level activities (top-down approaches) and they predict and test the organization of macromolecules into functional modules that play a role in higher-level activities (bottom-up approaches). We suggest including molecular mechanistic reasoning in biology education and we identify criteria for designing such education. Education using molecular mechanistic reasoning can build on common intuitive reasoning about mechanisms. The heuristics that scientists use can help students to apply this intuitive notion to the levels in between molecules and cells. 相似文献

Résumé Après avoir distingué différentes conceptions possibles de la liaison entre école et communauté locale (banalisation des équipements scolaires, intégration des équipements éducatifs, culturels et sociaux, ouverture de la pédagogie sur la vie réelle, contrôle et participation des parents et des usagers), l'auteur attribue les difficultés d'insertion et d'adaptation communautaires du système scolaire français à une tradition de centralisation administrative et bureaucratique (qui se manifeste dans la conception des programmes et méthodes d'enseignement aussi bien que dans le recrutement et la gestion des personnels). Parmi les innovations pédagogiques récentes susceptibles d'aller dans le sens d'une meilleure liaison entre école et communauté, on peut retenir surtout certaines expériences d'intégration architecturale et fonctionnelle d'équipements à vocation éducative, culturelle ou sociale conçues dans une perspective de participation et de déségrégation communautaire (cf. par exemple les réalisations d'Yerres, d'Istres et surtout de la Villeneuve de Grenoble). De telles expériences s'avèrent cependant difficilement généralisables dans le contexte français, de même que s'avèrent difficiles à mettre en oeuvre le contrôle des parents d'élèves sur le fonctionnement des établissements ou l'ouverture des contenus de l'enseignement sur les réalités du milieu local.
The author distinguishes between the different ways in which it is possible for the school to relate with the local community — by making school equipment generally available, by integrating the educational, social and cultural resources, by opening up education to real life, and by participation and control by parents and users. The difficulty for the French school system to penetrate and adapt itself to the communities in which it functions, is attributed to the tradition of administrative and bureaucratic centralisation manifested in the conception of teaching programmes and methods, as well as in the recruitment and management of personnel. Among recent educational innovations that could lead to a better association of the school with the community, one might mention first and foremost certain experiments concerned with the architectural and functional integration of educational, cultural and social facilities, conceived in a perspective of participation and desegregation of the community (e.g., in Yerres, Istres, and specially in Villeneuve, Grenoble). However, in the French context, such experiments are difficult to generalise from. It is equally difficult to effect any kind of control by parents over the functioning of educational institutions, or to open the curriculum to the realities of the local environment.
Zusammenfassung Zunächst unterscheidet der Verfasser zwischen verschiedenen möglichen Konzeptionen von der Verbindung der Schule mit der örtlichen Gemeinschaft (Zugänglichkeit der Schulausstattung, Integration der pädagogischen, kulturellen und sozialen Einrichtungen, Öffnung der Pädagogik auf die Wirklichkeit, Kontrolle und Teilnahme von Eltern und Benutzern). Die Schwierigkeiten des französischen Schulsystems, sich in die Gemeinde einzufügen und ihr anzupassen, schreibt er dem traditionellen administrativen und bürokratischen Zentralismus zu, der sich sowohl in der Konzeption der Lehrprogramme und -methoden als auch in der Einstellung und Führung der Lehrkräfte kundtut. Zu neueren pädagogischen Innovationen, die zu besserer Verbindung der Schule mit der Gemeinschaft führen könnten, gehören vor allem gewisse Beispiele architektonischer und funktioneller Integration von pädagogischen, kulturellen und socialen Einrichtungen im Hinblick auf Teilnahme und Einschluß der Gemeinschaft (wie z.B. realisiert in Yerres, Istres, und vor allem Villeneuve bei Grenoble). Derartige Neuerungen sind allerdings in Frankreich schwer generalisierbar, und auch Kontrolle der Institutionen durch die Eltern sowie Öffnung der Lehrinhalte auf die Wirklichkeit der örtlichen Gegebenheiten sind nicht leicht in die Tat umzusetzen.相似文献

Based on the studies of Mauss (1935) and Bourdieu (1980) on the determination of body techniques by culture and social background, this study seeks to describe the rules, dispositions and habits specific to different forms of athletic running. It is based on a sample of 732 athletes, all of them are the members of French athletics clubs, comprising 220 sprinters, 213 half-distance runners and 299 long-distance runners. Sports practices are different depending on sub-culture affiliation, sociological characteristics and forms of commitment. This being said, simple links between variables should not be transformed into causal connections. Before drawing such conclusions, it is important to identify the nature of the sport studied. This shows that middle-distance and long-distance enthusiasts, traditionally classified in the same family, have less, in common, than those practising sprint and middle distance. These results potentially question the methodological groups and sociological interpretations made by researchers and sports science. 相似文献

Decolonizing love: ambivalent love in contemporary (anti)sexual movements of Taiwan and South Korea*
Pei Jean Chen 《Inter-Asia Cultural Studies》2018,19(4):551-567
ABSTRACTThis article problematizes the modern construction of “love” in colonial and contemporary Taiwan and South Korea through historicizing the concept from the nineteenth century to the present. The conception of modern love in East Asia emerged during the late nineteenth century that coincided with the beginnings of civilization and nation-building discourses advocating as a strong mediator for the reconfiguration of social and intimate relationships. In the case of colonial Taiwan and Korea, the colonial governments and intellectuals constantly pivoted on “exceptions” – obscene sex, indecent behavior or illegitimate subjects – to justify their political legitimacy/hegemony to love that prescribed a normative social relationship. Fully embraced by colonial Taiwan and Korea, this mechanism was extended to their postwar regimes; that is, love is celebrated and worshiped without the recognition of its underlying ideology of discrimination and exclusion. I coin the term “love unconscious” to characterize the colonial legacies of love in the contemporary social movements in Taiwan and South Korea. Furthermore I examine how both religious groups and LGBTQ activism were stuck in the “love unconscious” with two cases of contested love: the definition of love in the dictionary, and the rhetoric of love in (anti-)same-sex marriage movements. This article argues that Taiwan and South Korea's LGBTQ and marriage movements are based neither on Western discourses nor inspiration, but are instead driven by the reality and legacy of colonial history. To envisage the decolonization of love is to deconstruct the love unconscious and reconsider the history of colonial love. 相似文献

The effects of signaled reward were examined using DRL and DRH schedules of reinforcement. In each case, one group of rats received a brief cue between the reinforced response and the reward, and a second group received brief cues at random times. With the DRL schedule (Experiment 1), signaled reward decreased response rate, increased response efficiency (number of responses per reinforcer), and increased resistence to satiation relative to the control group. With the DRH schedule (Experiment 2), signaled reward increased response rate, efficiency, and resistance to satiation. These results refute an overshadowing explanation of the effects of signaled reward and suggest that food-correlated cues enhance learning of the reinforcement contingencies. 相似文献

Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and perceived cognitive load in relation to visual-spatial abilities. In a double-center randomized controlled trial, first-year (bio)medical undergraduates studied lower extremity anatomy in an interactive 3D AR environment either with a stereoscopic 3D view (n = 32) or monoscopic 3D view (n = 34). Visual-spatial abilities were tested with a mental rotation test. Anatomical knowledge was assessed by a validated 30-item written test and 30-item specimen test. Cognitive load was measured by the NASA-TLX questionnaire. Students in the stereoscopic 3D and monoscopic 3D groups performed equally well in terms of percentage correct answers (written test: 47.9 ± 15.8 vs. 49.1 ± 18.3; P = 0.635; specimen test: 43.0 ± 17.9 vs. 46.3 ± 15.1; P = 0.429), and perceived cognitive load scores (6.2 ± 1.0 vs. 6.2 ± 1.3; P = 0.992). Regardless of intervention, visual-spatial abilities were positively associated with the specimen test scores (η2 = 0.13, P = 0.003), perceived representativeness of the anatomy test questions (P = 0.010) and subjective improvement in anatomy knowledge (P < 0.001). In conclusion, binocular disparity does not improve learning anatomy. Motion parallax should be considered as another important depth cue that contributes to depth perception during learning in a stereoscopic 3D AR environment. 相似文献
