La efectividad de diferentes métodos de la enseñanza de la lecto-escritura en español. Una revisión de literatura

Para la enseñanza de lecto-escritura de español en niños existen diferentes métodos usados por los profesores. La importancia de los métodos de lecto-escritura usados para los niños de la primera infancia se vincula con el futuro educativo y profesional de la persona. Por tanto, la preocupación de este trabajo es hacer una revisión de literatura sobre cuáles son los métodos usados por las diferentes instituciones y evaluar la efectividad de dichos métodos en la enseñanza de lecto-escritura. Se hace la revisión de 26 artículos, de los cuales 15 son estudios hechos por diferentes autores para evaluar la efectividad de los diferentes métodos. En el contexto de los artículos revisados se encuentra el método global, el sintético, el fonético, el silábico, el ecléctico, junto con estrategias pictofónicas y el programa de Experiencias Comunicativas en Situaciones variadas de lectura y escritura (ECOS). Los hallazgos permiten concluir que sí hay métodos más efectivos que otros en la enseñanza de lecto-escritura de español en niños. También se puede concluir de acuerdo a la revisión, que la familiaridad de las palabras y el entrenamiento en habilidades fonológicas juega un papel importante en el desempeño de los niños en la realización de las diferentes tareas.

Preliminary Remarks on Old Spanish Auxiliares: haber, ser and estar

En aquest article s'intenta aportar una visió descriptiva del funcionament d'haber, ser i estar en construccions 'perifràstiques' del castellà medieval. Quant a les perífrasis 'AUX+ infinitiu', s'observa que no s'ajusten a una anàlisi del tipus 'SV que selecciona un SV'. D'altra banda, s'aporta evidència que afavoreix una visió de la derivació dels futurs i condicionals analítics on el verb [-finit] s'excorpora de l'auxiliar funcional per traslladar-se a CO. Finalment, s'estableix que les construccions 'haber/ser/estar+participi' poden ser analitzades com a verbs lèxics que subcategoritzen una oració reduïda el predicat de la qual és el participi. Això permet relacionar l'avantposició de participi amb la dels SA i la dels arguments interns. Els aspectes bàsics d'aquest canvi sintàctic que duu del castellà medieval i preclàssic a l'espanyol actual són: (a) la categoria lèxica SV dels verbs en qüestió es reanalitza com una categoria funcional SAsp i aquests verbs esdevenen auxiliars; (b) hi ha un canvi de subcabgorització, ja que aquests verbs deixen de subcategoritzar una oració reduïda per passar a subcategoritzar un SVmàx, i (c) la pèrdua de la projecció màxima SCONC1 comporta la desparició dels efectes de la llei Tobler-Mussafia, de la possibilitat d'avantposar el participi i també de la concordança de participi en els perfets compostos.

Towards the computer-aided diagnosis of dementia based on the geometric and network connectivity of structural MRI data

We present an intuitive geometric approach for analysing the structure and fragility of T1-weighted structural MRI scans of human brains. Apart from computing characteristics like the surface area and volume of regions of the brain that consist of highly active voxels, we also employ Network Theory in order to test how close these regions are to breaking apart. This analysis is used in an attempt to automatically classify subjects into three categories: Alzheimer’s disease, mild cognitive impairment and healthy controls, for the CADDementia Challenge.

Os resultados obtidos permitiram a análise do comportamento dos alunos diante da nova maneira de se estudar e, ainda, um confronto de suas opiniões com as vantagens e restrições encontradas na literatura. A experiência vivenciada pelo pesquisador durante o experimento, permitiu-lhe concluir que o estudo desenvolvido foi importantíssimo na sua carreira, como professor de contabilidade e, ainda, como educador preocupado com aspectos de um ensino crítico. O estudo permitiu que fossem sugeridas recomendações ao governo, universidades, editores e professores sobre a utilização desta nova ferramenta de ensino e sugestões sobre novas pesquisas nesta área.

Aprendizagem da língua japonesa apoiada por ferramentas computacionais: estudo e desenvolvimento do jogo Karuchā Ships Invaders

The use of technology tools for teaching and learning has grown increasingly in our daily life. In this context, a branch that has had tremendous growth is the area of teaching and learning language through computational tools. The study of CALL (Computer Assisted Language Learning), accomplished in this research, aims to evaluate existing tools in this context, focused specifically on the Japanese language; and from this study, accomplish the development of a new computational tool that can assist teaching/learning of the Japanese language. As results, we present a wide survey on the subject in various technologies/devices, as well as the complete development process of a new tool, the Karuchā Ships Invaders game, that proposes to teach basic concepts of the language, blended with entertainment, and still, focusing on the Brazilian students of Japanese language audience. We will present all the concept phases of the game and its evolution through the research, as well as an interface evaluation. Still, we present proposal and validation of a method to evaluate motivational aspects of computational tools with educational focus, and results extracted from an experiment accomplished with prospective users

Computer-Guided Surgery in Implantology: Review of Basic Concepts

The aim of the present study was to conduct a critical literature review about the technique of computer-guided surgery in implantology to highlight the indications, purposes, immediate loading of implants and complications, protocol of fabrication, and functioning of virtual planning software. This literature review was based on OLDMEDLINE and MEDLINE databases from 2002 to 2010 using the key words "computer-guided surgery" and "implant-supported prosthesis." Thirty-four studies regarding this topic were found. According to the literature review, it was concluded that the computer-assisted surgery is an excellent treatment alternative for patients with appropriate bone quantity for implant insertion in complete and partially edentulous arches. The Procera Nobel Guide software (Nobel Biocare) was the most common software used by the authors. In addition, the flapless surgery is advantageous for positioning of implants but with accurate indication. Although the computer-guided surgery may be helpful for virtual planning of cases with severe bone resorption, the conventional surgical technique is more appropriate. The surgical guide is important for insertion of the implants regardless of the surgical technique, and the success of immediate loading after computer-guided surgery depends on the accuracy of clinical and/or laboratorial steps.

A coleta de corpus de aprendizes: questões qualitativas em uma pesquisa sobre a escrita de aprendizes de língua espanhola

In this paper we discuss and present the first results gathered from the compilation of a learner corpus comprised of texts written by university students (Language, Literature and Translation Course). We made use of Corpus Linguistics and observations of researchers from the learner’s corpus field, in order to compile and analyze a corpus of argumentative and descriptive texts written in Spanish. Four hundred compositions were collected (about 120 thousand words) from August 2011 to December 2012. The methodology adopted assisted us considerably in maintaining a comprehensive working agenda, taking into consideration students’ needs and using the data collected as subsidy to improve classroom management of content. We also present the difficulties faced during the data gathering and propose procedures do avoid or minimize them.

A educação de professores de línguas em CALL: histórico e perspectivas

Over the last years, the new technologies have changed the way we relate to information and communicate with other people, which has brought on impact to foreign language teaching and learning, and, consequently, to the area of foreign language teacher education. The abbreviation CALL (Computer Assisted Language Learning) has been used to designate the processes of language teaching and learning with the use of computers, and language teacher education in CALL to name teacher education for and with the use of new technologies, since a number of authors point to the interdependence of both processes. We intend in this article to present an overview of the literature of the area of language teacher education in CALL nowadays and discuss issues related to the use of new technologies concerning its integration to teacher education and the functional and institutional roles to be taken. We also present two proposals of teacher education with the use of new technologies which are being implemented and at the same time studied in Brazil, which we believe have essential elements for the development of language teachers for and with the use of new technologies currently.

Fluorescence Level of Composites Assessed by Computer Processing of Digital Images - ScanWhite

The human dentition is naturally translucent, opalescent and fluorescent. Differences between the level of fluorescence of tooth structure and restorative materials may result in distinct metameric properties and consequently perceptible disparate esthetic behavior, which impairs the esthetic result of the restorations, frustrating both patients and staff. In this study, we evaluated the level of fluorescence of different composites (Durafill in tones A2 (Du), Charisma in tones A2 (Ch), Venus in tone A2 (Ve), Opallis enamel and dentin in tones A2 (OPD and OPE), Point 4 in tones A2 (P4), Z100 in tones A2 ( Z1), Z250 in tones A2 (Z2), Te-Econom in tones A2 (TE), Tetric Ceram in tones A2 (TC), Tetric Ceram N in tones A1, A2, A4 (TN1, TN2, TN4), Four seasons enamel and dentin in tones A2 (and 4SD 4SE), Empress Direct enamel and dentin in tones A2 (EDE and EDD) and Brilliant in tones A2 (Br)). Cylindrical specimens were prepared, coded and photographed in a standardized manner with a Canon EOS digital camera (400 ISO, 2.8 aperture and 1/ 30 speed), in a dark environment under the action of UV light (25 W). The images were analyzed with the software ScanWhite©-DMC/Darwin systems. The results showed statistical differences between the groups (p < 0.05), and between these same groups and the average fluorescence of the dentition of young (18 to 25 years) and adults (40 to 45 years) taken as control. It can be concluded that: Composites Z100, Z250 (3M ESPE) and Point 4 (Kerr) do not match with the fluorescence of human dentition and the fluorescence of the materials was found to be affected by their own tone.

Masculinities in Conflict: Representations of the Other in Narrative during the Spanish Civil War

In this article, I analyze the representation of the Other in three texts that were published during the Spanish Civil War: El infierno azul (1938?), by Republican Isidro R. Mendieta, and two closely related works by Falangist Jacinto Miquelarena: Cómo fui ejecutado en Madrid (1937) and El otro mundo: La vida en las embajadas de Madrid (1938). Although these texts adhere to different political ideologies and are stylistically very divergent, they are similar in their constant criticisms of the enemy. Furthermore, both Republicans and rebels tend to depict the enemy as possessing an inadequate masculinity. He is described, on one hand, as a beast or an animal, unable to control his instincts, and, on the other hand, as an unmanly and effeminate coward. Thus, for the construction of the nation, the Other presents an inappropriate masculinity, which is either excessive and uncontainable, or insufficient. Therefore, national ideologies seem to propose a normative masculinity that is located in an ambiguous middle ground: a masculinity that is able to control animal instincts yet capable of heroic acts.
