There are two basic guiding referents in the present investigation: the teaching and learning of school-level geometry (basic concepts of Euclidian geometry and measure) and the analysis of the conceptions of prospective primary teachers in Spain. The work assumes that such conceptions appear and develop during school years, and that consequently, for the prospective teachers to learn to teach mathematics, account must be taken of the requirements that arise from these conceptions themselves and from the prospective teachers’ knowledge of school-level mathematics. The objective of the study was to describe and analyse prospective primary teachers’ conceptions of school-level geometry and it teaching and learning. To this end, we considered the hypothesis that the students’ memories and expectations provide information with which to characterize their conceptions of the field of geometry and its teaching/learning at the primary school level. 相似文献

Ball screens are one of the most frequently used tactical behaviour in elite basketball games. The aim of the present study was to identify their predictors of success related to time, space, players, and tasks performed. The sample was composed of 818 ball screens corresponding to 20 close games (mean differences in score of 3.1 ± 0.8 points) randomly selected from the playoff games of the Spanish Basketball League (2008–2011). Classification tree analysis (CHAID) was used to analyse which variable or combination of variables, better predicts effectiveness during ball screens. The main results allowed identifying interactions with dribbler actions after the screen and the orientation of the screen on the ball. The results showed no interaction with game quarter and quarter minute temporal-related variables in both analyses. The present findings allow improving coaches’ strategic plans that involve selecting the most appropriate offensive approach when performing ball screens. 相似文献

As an important element in the cultural heritage of a people, traditional rural constructions need to be conserved over time. Graphic and metric documentation methods play a key role in the preservation of cultural heritage. In this paper different existing methods of graphic and metric documentation are analysed in order to select the most suitable for the documentation of agro-industrial buildings according to their characteristics. The selected one is a simple close-range photogrammetry method, which is affordable and easy to understand for non experts. It is based on the use of plumb lines, a conventional digital camera and monoscopic restitution. The application of the method is illustrated in a particular case consisting on the graphic and metric documentation of a windmill. Also the accuracy of the method is evaluated in this particular case. 相似文献

The seismic assessment of art objects requires a multidisciplinary approach and the definition of a specific methodology for evaluating the level of safety and the possible interventions necessary for seismic risk prevention, finding a compromise between safety and conservation. This paper describes a first step in this direction, in which the different aspects of the procedure, from knowledge path of the art object to the structural analysis, were studied in the six Michelangelo's statues located in the “Galleria dei Prigioni” (Slaves’ Gallery) at the Accademia Gallery of Florence. We showed that the general principles and criteria expressed in the “Italian Guidelines for evaluation and mitigation of seismic-risk to cultural heritage”, which are specifically devoted to masonry constructions, could be profitably extended to other artworks, like statues, starting from historical research, geometrical survey and material characterization, up to the developing of specific methods of analysis. This research could be the base for future studies to be performed concerning the prevention of seismic damage of art objects, including both bare minimum interventions and specific devices, such as isolation systems. 相似文献

La incidencia de las competencias lingüistícas del escolar sobre las adquisiciones escolares en las demás áreas del currículum es una realidad que todos los maestros pueden comprobar día a día. En este trabajo se investiga esa incidencia, medida a través de la variable fracaso escolar, y sus resultados podrían permitir extraer algunos principios de intervención educativa precoz en algunos aspectos del lenguaje cruciales para la escolaridad posterior. 相似文献

We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher’s conceptions
of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when
teaching science lessons. The data gathering procedures were interviews analyzed by means of cognitive maps and classroom
observations. The results reflected Miguel’s relativist conceptions of the nature of science that were consistent with his
constructivist orientation in learning and teaching. In the classroom, however, he followed a strategy of transmission of
external knowledge based exclusively on teacher explanations, the students being regarded as mere passive receptors of that
knowledge. Miguel’s classroom behavior was completely contrary to his conceptions, which were to reinforce the students’ alternative
ideas through debate, and not by means of teacher explanation. 相似文献

While adherence to medication remains a problematic area in the care of chronically ill elderly, an extended model that incorporates the interaction of studied variables remains a blank spot. Anchored on Ajzen's Theory of Planned Behavior, this article details our efforts to develop and test a model of medication adherence among Filipino elderly relative to their medication belief, follow-up visits, consultation satisfaction, memory task, trust with physician, perceived stress, memory strategies, social support, memory load, depression, length of time taking the medication, number of conditions, and self-efficacy with medication adherence. Structural equation modeling (SEM) was employed to study causalities among all parameters. With the participation of 325 older adults located in District IV, Sampaloc, Manila, data needed were gathered through a multiaspect questionnaire consisting of a robotfoto, a memory strategy usage measure, an eight-scale Morisky Medication Adherence Scale, a 15-item Geriatric Depression Scale, a General Self-efficacy Scale, a Consultation Satisfaction Questionnaire, and a Perceived Stress Scale. Data were analyzed using AMOS version 19. Results revealed that depression, trust with physician, and number of conditions affect adherence positively, while event-based memory, consultation satisfaction, memory load, and external memory strategy affect it otherwise. Some suggested variables were found to have no impact at all. As this study reveals, careful consideration should be given to multiple factors, and their interrelationship should be examined well. Because many factors can influence medication adherence behavior of the elderly, and because the reasons for their noncompliance are also varied, multifaceted solutions must be developed. 相似文献
