ResumenEl objetivo fundamental de este trabajo es el estudio conjunto de los principales factores que determinan el conocimiento y la representación del entorno en los invidentes, haciendo especial énfasis en las relaciones entre desarrollo y aprendizaje. El marco teórico se toma de la psicologia ambiental y de la psicología evolutiva del conocimiento espacial. El procedimiento consiste en el aprendizaje de un entorno desconocido, en un máximo de cuatro sesiones. El conocimiento espacial se evalúa mediante tres tipos de técnicas. Los resultados no muestran, en términos generales, grandes diferencias entre ciegos de nacimiento y ciegos tardíos, ni tampoco entre el espacio pequeño y el grande. Las diferencias más significativas son las debidas a la edad de los sujetos, y el aprendizaje también se revela como factor importante, aunque en nuestro diseño parezca estar subordinado al desarrollo. La investigaáón tiene implicaciones claras para la instrucción de la orientación, movilidad y conocimiento del entorno en los invidentes. 相似文献

ResumenLos datos lingüísticos fueron registrados mediante un vídeo en un contexto natural y habitual del niño. Se analiza el lenguaje desde los tres planos lingüísticos, sintáctico, semántico y pragmático. Además, para observar el nivel de desarrollo lingüístico, se comparó la producción del lenguaje del sujeto estudiado con la de otro niño cuyo desarrollo es adecuado.Tras los resultados obtenidos del trabajo, se puede concluir que los factores externos, en los aspectos que están relacionados a pautas de cuidado y de interacción diádica adulto-niño, son fundamentales para la adecuada adquisición y desarrollo lingüístico y, además, la rehabilitación del mismo no es muy esperanzadora. 相似文献

This study looks at the perceived ability of components of IT infrastructure integration and supply chain process integration to predict specific radio frequency identification (RFID) system deployment outcomes—exploration, exploitation, operational efficiency, and market knowledge creation. Data for this pilot research study was collected using a survey questionnaire administered online to members of the Council of Supply Chain Management Professionals (CSCMP). It was hypothesized that data consistency and cross-functional application integration, both elements constituting IT infrastructure integration, and information flow integration, physical flow integration, and financial flow integration, all elements constituting supply chain process integration would be positively associated with and predict the four RFID system outcomes. Multiple regression results show partial support for all four proposed hypotheses. Cross-functional application integration and financial flow integration predicted exploration, while data consistency and physical flow integration predicted exploitation. Data consistency and cross-functional application integration, on the other hand, predicted both operational efficiency and market knowledge creation. Supply chain managers planning to deploy RFID systems are alerted to the criticality of these IT infrastructure issues as they brace for a likely widespread implementation of RFID in supply chains they participate in. 相似文献

Previous research has been done to identify the best pragmatic approach that DBMSs must follow to manage different workloads. Some approaches have followed the “One size fits all” approach, trying to incorporate all features in a row-oriented DBMS (also called horizontal) to manage both OLTP and DSS workloads. Additionally, there have been specialized DBMS, following a columnar approach (also called vertical), that focuses on the growing demand to efficiently manage DSS workloads. This paper proposes a combination of both vertical and horizontal DBMS to best manage OLTP and DSS workloads. We have used mature, commercially available products from a single vendor and developed a custom middleware Decision Query Module that identifies the best option for most efficient execution of a query. This V + H architecture also offers the functionality of a mirrored DB without paying twice for storage. 相似文献

Nowadays, universities tend to promote more learner-centred learning, creating a more interactive and motivational environment for students and teachers. This paper describes an expanded framework to help chemical educators to construct a quiz for solution of chemical exercises in their courses. The novelty of this contribution is that the proposed tool combines a flashcards-based method with knowledge pills. The framework has three levels: definition of problem for a teacher; the quiz; use of the quiz for the student. The tool could provide predefined or automatically generated exercises of chemicals. Students could practise where and whenever they like via the Internet. Theirs answers would be registered automatically by the tool and if the students have doubts about any of the questions, they can see a knowledge pill with a teacher explanation about the solution of the exercise. Moreover, they would be able to check their scores from the tests. Once the flashcards were designed and produced, the opinions of other lecturers and students about them were considered. Both groups considered that the tool could be useful to improve the students’ learning process. For future work, this design will be used with the students and its effectiveness will be analysed. 相似文献

ResumenDurante los últimos años, los trabajos sobre el aprendizaje de las ciencias han estado dominados por dos enfoques contrapuestos: la teoría piagetiana de las operaciones formales y el enfoque de las ideas previas o concepciones alternativas. Frente a estos dos enfoques los autores proponen una alternativa intermedia basada en el concepto de «teorías implícitas». Estas teorías serían teorías personales que, como las teorías científicas, sirven para organizar y predecir el mundo circundante. No obstante, presentan también características muy diferentes de las teorías científicas tanto en lo referente a su contenido como a su organización. Estas diferentes características tienen, como se expone en el artículo, importantes consecuencias tanto para la investigación como para la práctica educativa. 相似文献

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

Basic and superior reasoning skills are woven into the clinical reasoning process just as they are used to solve any problem. As clinical reasoning is the central competence of medical education, development of these reasoning skills should occur throughout the undergraduate medical curriculum. The authors describe here a method of teaching reasoning skills in a clinical context during a human anatomy course. Anat Sci Educ 3:267–271, 2010. © 2010 American Association of Anatomists. 相似文献

OBJECTIVES: The purpose of this 5-year study was to improve detection in two consecutive phases: (a) To close the gap between the number of identified cases and the actual number of cases of child abuse by increasing detection; and (b) To increase the possibility of a broader spectrum of detection. METHOD: The Balearic Islands (one of the Autonomous Communities of Spain, with 161,287 children under 18 years old) was selected as the study area. Phase 1: front-line professionals (181) from all the health and social services agencies were trained in detection. Phase 2, school professionals (251) from all schools in the territory were also trained. The independent factor was the intervention provided to the professionals with training and support. A pre-post design was used over the area, divided in territories, in which the program was gradually implemented to provide within-territory and between-territories controls. RESULTS: Phase 1: Comparison before-after implementation of the program showed that detection was tripled in the Balearic Islands (from .58 to 1.77 per 1,000 children). An unplanned generalization effect was found, and post hoc analysis considering only the islands showed the expected increase. Phase 2: A subsequent increased detection rate was found in Child Protection Services cases 2.18 per 1,000. Of those new cases, 24.5% came from schools, after controlling for duplication. CONCLUSIONS: This detection system showed positive changes after training and supporting frontline health and social services professionals. However, these professionals only have occasional contacts with the child population. Therefore, to broaden the spectrum of detection and to reach more maltreated children, who are less likely to be visible to CPS, it is necessary to train and support school professionals because of the frequency of their contacts with children on an almost daily basis. 相似文献
