Intervenção mediacional na aprendizagem do braille: um estudo com crianças deficientes visuais

This study aimed to construct and evaluate a proposed mediational intervention with preschool children through reading workshops and writing in Braille system. The proposal is based on the concepts of Vygotsky on defectology and approach to the Mediated Learning Experience (MLE) developed by Feuerstein. For the research were drawn up ten Mediational workshops, in which they developed a work by reading a children's story and from her reading activities and writing in Braille system. The workshops took place within in kindergarten room of the institution. Study participants were four blind children, six and seven years in an institution that assists visually impaired people in the city of Uberaba / MG, and their mothers and the teacher responsible for the room in which they study. During the workshops, the children showed interest in participating in the activities of reading and writing in Braille. We believe that the data built during the research are not sufficient to establish a generalization, due to the small number of participants. However, at the end of the workshops and the assessment of participants' responses can infer the relevance of the proposal, because in addition to the interest shown and the request of the children there were more activities like that, it was noticed greater fluency in reading and greater ease in writing.

El álgebra en la enseñanza inclusiva de la matemática Braille: estrategias didácticas en el 3er. ciclo de la enseñanza básica en Portugal

“Las Escuelas deben de reconocer y satisfacer las necesidades de sus alumnos, adaptándose a los varios estilos y ritmos de aprendizaje, con el fin de garantizar un buen nivel en la educación, para todos a través de curricula adecuados, de una buena organización escolar, de estrategias pedagógicas, de utilización de recursos y de una cooperación con las respectivas comunidades. Son precisos, por tanto, un conjunto de apoyos y de servcios para satisfacer ese conjunto de necesidades especiales dentrto de la Escuela”, “con todo ello y aunque, sin embargo, los compromisos internacionales, asumidos por los políticos, sean muy importantes, éstos no desencadenan, por sí solos, prácticas diferentes en las comunidades a las que van dirigidos” y, como comprueban diversos estudios, la formación inicial de los profesores no ha desarrollado en los docentes la práctica de estrategias inclusivas. La investigación presente pretende elaborar algunos puntos de convergencia entre la orientación der las políticas educativas mundiales, la investigación realizada en ese ámbito y las prácticas lectivas actuales, dado que “Los profesionales de la educación se enfrentan en la práctica con innumerables problemas. En vez de aguardar soluciones venidas del exterior, muchos de ellos procuran investigarlos directamente”. Afirmamos que es posible enseñar en las circunstancias más difíciles, si utilizamos los medios y los recursos necesarios, y para ello es imprescindible la creatividad, trabajo, y conocer los medios, para que la enseñanza sea realmente eficaz. El presente trabajo de investigación, tiene como motivos principales diseñar, aplicar y evaluar estrategias inclusivas que permitan transmitir el conocimiento algebraico a todos los alumnos de una sección de enseñanza regular, que incluye a los alumnos invidentes, de tal modo que puedan responder a la cuestión: ¿Qué estrategias de enseñanza y qué recursos educativos será necesario diseñar y aplicar para que estos alumnos logren adquirir el conocimiento algebraico en el 3er, Ciclo de la Enseñanza Básica en Portugal, de modo semejante a como lo hacen los restantes del grupo? Para ello se ha procurado, a través del paradigma de investigación interpretativa, descriptiva y cualitativa, según una metodología de investigación-acción, basándose en un estudio de caso: a) conocer las características, limitaciones y las dificultades consecuentes de la grafía Matemática Braille (GMB), las cuales, aunque puedan no estar directamente relacionadas con el estudio en cuestión, subyacen bajo él; b) identificar las dificultdes mayores que tienen los alumnos invidentes en el aprendizaje del Álgebra, partir de esto mismo. c) diseñar estrategias de organización y gestión del aula para la inclusión de alumnos invidentes en actividades algebraicas, utiizando los recursos pedagógicos existentes en el contexto del presente estudio; así como: d) Evaluar el impacto de la aplicación de un amplio campo de actividades de carácter exploratorio, que posibiliten a dichos alumnos desarrollar su propio raciocinio matemático, especialmente en el ámbito del álgebra y así evolucionar en su proceso de enseñanza-aprendizaje...

Determination of preventive maintenance lead time using hybrid analysis

The time for conducting Preventive Maintenance (PM) on an asset is often determined using a predefined alarm limit based on trends of a hazard function. In this paper, the authors propose using both hazard and reliability functions to improve the accuracy of the prediction particularly when the failure characteristic of the asset whole life is modelled using different failure distributions for the different stages of the life of the asset. The proposed method is validated using simulations and case studies.

Leveraging sponsorships on the Internet: Activation, congruence, and articulation

This paper considers how the Internet can be used to leverage commercial sponsorships to enhance audience attitudes toward the sponsor. Definitions are offered that distinguish the terms leverage and activation with respect to sponsorship-linked marketing; leveraging encompasses all marketing communications collateral to the sponsorship investment, whereas activation relates to those communications that encourage interaction with the sponsor. Although activation in many instances may be limited to the immediate event-based audience, leveraging sponsorships via sponsors' Web sites enables activation at the mass-media audience level. Results of a Web site navigation experiment demonstrate that activational sponsor Web sites promote more favorable attitudes than do nonactivational Web sites. It is also shown that sponsorsponsee congruence effects generalize to the online environment, and that the effects of sponsorship articulation on audience attitudes are moderated by the commerciality of the explanation for the sponsor-sponsee relationship. Importantly, the study reveals that attitudinal effects associated with variations in leveraging, congruence, and orientation of articulation may be sustained across time.

Dynamic matrix control on wind-induced vibration of spatial latticed structures [Chinese title = 空间网壳结构风振抑制的动态矩阵预测控制分析]

Ameliorated strategies were put forward to improve the model predictive control in reducing the wind induced vibration of spatial latticed structures. The dynamic matrix control (DMC) predictive method was used and the reference trajectory which is called the decaying functions was suggested for the analysis of spatial latticed structure (SLS) under wind loads. The wind-induced vibration control model of SLS with improved DMC model predictive control was illustrated, then the different feedback strategies were investigated and a typical SLS was taken as example to investigate the reduction of wind-induced vibration. In addition, the robustness and reliability of DMC strategy were discussed by varying the model configurations.

Evaluation of polycaprolactone scaffold degradation for 6 months in vitro and in vivo

The use of polycaprolactone (PCL) as a biomaterial, especially in the fields of drug delivery and tissue engineering, has enjoyed significant growth. Understanding how such a device or scaffold eventually degrades in vivo is paramount as the defect site regenerates and remodels. Degradation studies of three-dimensional PCL and PCL-based composite scaffolds were conducted in vitro (in phosphate buffered saline) and in vivo (rabbit model). Results up to 6 months are reported. All samples recorded virtually no molecular weight changes after 6 months, with a maximum mass loss of only about 7% from the PCL-composite scaffolds degraded in vivo, and a minimum of 1% from PCL scaffolds. Overall, crystallinity increased slightly because of the effects of polymer recrystallization. This was also a contributory factor for the observed stiffness increment in some of the samples, while only the PCL-composite scaffold registered a decrease. Histological examination of the in vivo samples revealed good biocompatibility, with no adverse host tissue reactions up to 6 months. Preliminary results of medical-grade PCL scaffolds, which were implanted for 2 years in a critical-sized rabbit calvarial defect site, are also reported here and support our scaffold design goal for gradual and late molecular weight decreases combined with excellent long-term biocompatibility and bone regeneration.

Real world contexts in PISA science : implications for context-based science education

The PISA assessment instruments for students’ scientific literacy in 2000, 2003 and 2006 have each consisted of units made up of a real world context involving Science and Technology, about which students are asked a number of cognitive and affective questions. This paper discusses a number of issues from this use of S&T contexts in PISA and the implications they have for the current renewed interest in context-based science education. Suitably chosen contexts can engage both boys and girls. Secondary analyses of the students’ responses using the contextual sets of items as the unit of analysis provides new information about the levels of performance in PISA 2006 Science. .Embedding affective items in the achievement test did not lead to gender/context interactions of significance, and context interactions were less than competency ones. A number of implications for context-based science teaching and learning are outlined and the PISA 2006 Science test is suggested as a model for its assessment.

The role of sensation seeking and need for cognition on web-site evaluations : a resource-matching perspective

The Internet theoretically enables marketers to personalize a Website to an individual consumer. This article examines optimal Website design from the perspective of personality trait theory and resource-matching theory. The influence of two traits relevant to Internet Web-site processing—sensation seeking and need for cognition— were studied in the context of resource matching and different levels of Web-site complexity. Data were collected at two points of time: personality-trait data and a laboratory experiment using constructed Web sites. Results reveal that (a) subjects prefer Web sites of a medium level of complexity, rather than high or low complexity; (b)high sensation seekers prefer complex visual designs, and low sensation seekers simple visual designs, both in Web sites of medium complexity; and (c) high need-for-cognition subjects evaluated Web sites with high verbal and low visual complexity more favourably.

The on-road difficulties of older drivers and their relationship with self-reported motor vehicle crashes

OBJECTIVES: To quantify the driving difficulties of older adults using a detailed assessment of driving performance and to link this with self-reported retrospective and prospective crashes. DESIGN: Prospective cohort study. SETTING: On-road driving assessment. PARTICIPANTS: Two hundred sixty-seven community-living adults aged 70 to 88 randomly recruited through the electoral roll. MEASUREMENTS: Performance on a standardized measure of driving performance. RESULTS: Lane positioning, approach, and blind spot monitoring were the most common error types, and errors occurred most frequently in situations involving merging and maneuvering. Drivers reporting more retrospective or prospective crashes made significantly more driving errors. Driver instructor interventions during self-navigation (where the instructor had to brake or take control of the steering to avoid an accident) were significantly associated with higher retrospective and prospective crashes; every instructor intervention almost doubled prospective crash risk. CONCLUSION: These findings suggest that on-road driving assessment provides useful information on older driver difficulties, with the self-directed component providing the most valuable information.
