Educação bilíngue para surdos : um estudo acerca de práticas de letramento crítico com alunos surdos usuários da Língua Brasileira de Sinais

At a time when the issue of the inclusion of hearing-impaired students in regular schools has been discussed, it becomes necessary to reflect upon the relevance of a recurrent educational process in schools specialized in education for the hearing-impaired: the bilingual schools. Such institutions, still scarce in Brazil, offer an oriented and specialized education to hearing-impaired children and adolescents, since they have the Brazilian Sign Language as a language of instruction in all subjects, and the Portuguese written language as an additional language, which gives them the bilingual status. This research aims to investigate how the practices developed in my Portuguese classes in a bilingual school have contributed to the development of student‟s literacy, specifically the Critical Literacy (STREET, 1985, 1990, 1998), in two classes of hearing-impaired students enrolled in the final grades of elementary school. It is a qualitative, ethnographic research, which uses the triangulation system for analyzing data: (i) the pedagogical sequences; (ii) the students‟ activities and (iii) the teacher‟s and students‟ written accounts registered as field notes. Through the intersection of the data, this work evaluates whether students have achieved some level of Critical Literacy, and what kind of collaboration and/or activity is relevant during this process. This research is justified by the need to evaluate practices at bilingual schools that, although supported by current law in Brazil, are still a minority whose work is still not acknowledged or valued. The results show that activities using real texts of different genres can contribute to the development of Critical Literacy, and also to dynamic classes, with discussions about relevant topics to society in Sign Language. Also, activities that encourage students to do research and that provide to the hearing-impaired student, the understanding of the real usefulness of Portuguese as an instrument for the social inclusion of the hearing-impaired providing opportunities for them to change their social position can collaborate to this process.

Correlation between anxiety and academic self-concept in interpreter trainees

This paper focuses on two basic issues: the anxiety-generating nature of the interpreting task and the relevance of interpreter trainees’ academic self-concept. The first has already been acknowledged, although not extensively researched, in several papers, and the second has only been mentioned briefly in interpreting literature. This study seeks to examine the relationship between the anxiety and academic self-concept constructs among interpreter trainees. An adapted version of the Foreign Language Anxiety Scale (Horwitz et al., 1986), the Academic Autoconcept Scale (Schmidt, Messoulam & Molina, 2008) and a background information questionnaire were used to collect data. Students’ t-Test analysis results indicated that female students reported experiencing significantly higher levels of anxiety than male students. No significant gender difference in self-concept levels was found. Correlation analysis results suggested, on the one hand, that younger would-be interpreters suffered from higher anxiety levels and students with higher marks tended to have lower anxiety levels; and, on the other hand, that younger students had lower self-concept levels and higher-ability students held higher self-concept levels. In addition, the results revealed that students with higher anxiety levels tended to have lower self-concept levels. Based on these findings, recommendations for interpreting pedagogy are discussed.

Following instructions from working memory: Why does action at encoding and recall help?

Two experiments investigated the consequences of action at encoding and recall on the ability to follow sequences of instructions. Children aged 7–9 years recalled sequences of spoken action commands under presentation and recall conditions that either did or did not involve their physical performance. In both experiments, recall was enhanced by carrying out the instructions as they were being initially presented and also by performing them at recall. In contrast, the accuracy of instruction-following did not improve above spoken presentation alone, either when the instructions were silently read or heard by the child (Experiment 1), or when the child repeated the spoken instructions as they were presented (Experiment 2). These findings suggest that the enactment advantage at presentation does not simply reflect a general benefit of a dual exposure to instructions, and that it is not a result of their self-production at presentation. The benefits of action-based recall were reduced following enactment during presentation, suggesting that the positive effects of action at encoding and recall may have a common origin. It is proposed that the benefits of physical movement arise from the existence of a short-term motor store that maintains the temporal, spatial, and motoric features of either planned or already executed actions.

Experimental Evidence that Retaliation Claims Are Unlike Other Employment Discrimination Claims

The type of discrimination claim that strikes fear in the hearts of all employers is the dreaded retaliation claim. While employers contend, and plaintiffs admit, that retaliation is different from other discrimination complaints, employee advocates have put forth legislation that would equalize retaliation with the other types of discrimination. This bill, Protecting Older Workers against Discrimination Act (POWADA), would expand the so-called mixed-motive jury instruction to age, and disability, as well as retaliation. Moreover, it would allow plaintiffs, not judges, to decide which types of instruction the jury would receive. In this article, the authors argue that retaliation claims should not receive the same treatment as other discrimination claims (including age and disability), because it’s easy for juries to believe that retaliation is a factor, regardless of other facts. Once a fact-finding jury checks the box to indicate that an employer’s motive might include retaliation, the employer will likely have to pay fees and costs, at minimum, regardless of the claim’s final resolution.

Effet de la contingence entre l'atteinte du critère de maîtrise et l'activité subséquente sur le temps requis par des élèves en difficulté d'apprentissage pour atteindre ce critère

Bloom (1968) et Keller (1968) élaborèrent presque simultanément leur modèle d'organisation de l'enseignement. Ces modèles, la pédagogie de la maîtrise (mastery learning) et le système d'enseignement personnalisé (personalized system of instruction), quoique s'appuyant sur des contextes théoriques différents, possèdent plusieurs caractéristiques communes et fournissent un traitement pédagogique différencié selon le rendement démontré par l'élève. Les recherches entreprises sur les deux modèles, depuis la fin des années soixante, peuvent être divisées en deux courants de recherches. Un de ces courants évalue l'influence globale des modèles sur des variables comme le rendement scolaire, le degré de rétention de l'apprentissage, l'intérêt envers le contenu pédagogique, le concept de soi, le temps consacré à l'apprentissage, etc. Les premiers résultats des écrits expérimentaux de ce courant de recherche semblent convergés. Kulik, Jaska et Kulik (1978), dans une recension des écrits expérimentaux sur le système d'enseignement personnalisé appliqué au niveau collégial et universitaire, concluent que l'application de ce système entraine une amélioration du rendement scolaire et du niveau de rétention de l'apprentissage. Block et Burns (1976) parviennent à des conclusions semblables dans leur recension des écrits expérimentaux sur l'utilisation des deux modèles du niveau élémentaire au niveau universitaire. Un autre courant de recherche s'est appliqué à isoler l'effet spécifique des différentes composantes des modèles sur le rendement scolaire (Block et Burns, 1976; Kulik, Jaska et Kulik, 1978). L'effet spécifique des différentes composantes des modèles sur d'autres variables comme le temps consacré à l'apprentissage ou l'intérêt pour le contenu pédagogique n'a pas été, à notre connaissance, étudié jusqu'ici. Cette étude s'inscrit dans ces deux courants de recherche. Elle s'intéresse principalement à l'influence globale d'un ensemble de caractéristiques des deux modèles sur le rendement scolaire d'élèves en difficulté d'apprentissage de niveau primaire, ainsi qu'à l'effet d'une de ces caractéristiques sur le temps requis par ces élèves pour maîtriser leur apprentissage.

Teaching down or learning up

Résumé : L'élément important que cette thèse sous-tend est que l'enseignement efficace n'est pas seulement constitué de techniques et de méthodologie, mais plutôt d'attitude et d'approche envers l'enseignement. Ceci ne veut pas nécessairement dire que plusieurs méthodes d'enseignement reçues dans un cours avec l'intention d'optimaliser les mécanismes de transmission et d'assimilation de la matière sont inappropriées. Cependant, l'absence de ce que nous pourrions définir comme un ton pédagogique est essentiel, c'est-à-dire, qu'une attitude positive à la productivité autant vis-à-vis de la matière à transmettre que vis-à-vis de l'individu impliqué dans "l'acte" de réception versus la découverte, aura davantage de succès. Toute autre méthode sera complètement inefficace, inaccessible, voire même inutile. D'emblée, dans l'hypothèse de départ, l'argument principal présente une attitude générale d'enseignement à divers échelons ; soit au niveau secondaire ou collégial qui est inappropriée, incomplète ou négative. En d'autres mots, cette approche thérapeutise l'éducation. Dans l'exercice de cette approche, l'enseignant ou l'enseignante adopte plutôt le rôle d'un thérapeute que celui d'un éducateur. De ce fait, le professeur en situation a une approche plutôt de thérapeute que celle de maître-précepteur et que la matière présentée est souvent diluée, et réduite à des niveaux d'apprentissage accompagnés de carences notoires et d'échecs académiques. Les attentes d'une performance dans le milieu académique sont souvent des plus modestes. Cette même tendance d'une éducation à la baisse est évidente aussi dans le processus d'évaluation. Il est certain que dans les disciplines non scientifiques, l'évaluation formative a grandement suivi l'évaluation normative conduisant le précepteur, tour à tour, dans une évaluation dormative dans laquelle l'effort et l'intention remplacent les aptitudes et les habilitées réelles. Si l'approche pédagogique est vraiment l'élément crucial de l'éducation, il Importe que l'approche générale influence le climat de l'éducation contemporaine, de fait, devienne un palliatif contre-productif souvent réhabilitant. De plus, cette pseudo-thérapie d'où d'écoule une attitude exigeante envers l'enseignant et l'apprenant dont le fondement est la reconnaissance des impératifs culturels qui en sont le reflet et le corps doit-être affirmé et transposé dans la réalité. Cette dernière comprend des attentes très poussées en ce qui concerne la performance en classe et aussi le respect de la matière qui contient la présentation routinière et fondamentale; renouveau intense du processus d'évaluation qui fournira des standards communs et des objectifs externes dans l'évaluation du travail de l'étudiant. Cette connaissance et domestication empirique que nous présente Vygotsky dans un climat contemporain qu'il a expliqué ces termes comme "des zones de développement proximales" basées sur la doctrine suivante que le bon apprentissage précède le développement et que conséquemment s'ensuit une pédagogie d'apprentissage plutôt qu'une pédagogie centrée sur l'apprenant. L'application significative de ces derniers principes ou de ces épistémologiques s'imbriquent dans une situation d'apprentissage ascentionnel dont la structure est détaillée et considérée par différentes perspectives de la recherche qui suit.||Abstract : The central tenet of this thesis is that effective teaching is not only and perhaps not primarily a matter of technique and methodology but of attitude and approach. This is not to say that diverse methods of classroom instruction intended to optimize the mechanics of transmission and the assimilation of data are inappropriate but that in the absence of what we might denominate as a certain pedagogical tone. that is, a productive attitude toward both the material to be conveyed and the individuel engaged in the 'act' of reception-and-discovery, even the most powerful methods will be differentially unavailing or, at best, inefficient. Given this initial assumption, the argument proceeds that the general attitude toward instruction currently in place at the secondary echelons, that is, on the high school and college levels, may be popularly represented as a 'teaching down' approach, in other words, as one which seeks to therapeuticize education. In practice this means that the teacher tends to manifest in situ more as a therapist than as a preceptor, that the material to be presented is frequently diluted or scaled down to perceived levels of cognitive (dis)ability (as is also the case with the rate of instruction), and that performance expectations in the current pedagogical milieu are commonly quite modest. The same downward trend is evident in assessment protocols as well. Certainly in the nonscientific disciplines, normative evaluation has been widely succeeded by formative evaluation, leading in turn to a peculiar kind of dormative evaluation in which intangibles such as effort and intention may deputize for realized ability. If pedagogical approach is indeed the crucial element in instruction, and if the general approach that pervades the contemporary climate of instruction is indeed counter-productively remedial or rehabilitory, that is, therapeutic, then it should follow that a more demanding attitude toward teaching and learning founded on the recognition of the culturel imperative which teaching both reflects and embodies needs to be re-affirmed and translated into practice. This latter would entail the maintenance of high expectations with regard to classroom performance, a respect for the material which precludes its routine mitigation or debasement, a renewed insistance on grading protocols that provide an external, 'objective' or communal standard against which the student's work can be measured, the empirical acknowledgment or domestication of what Vygotsky has termed "the zone of proximal development," based on the doctrine that good learning proceeds in advance of development, and conséquently, a learning-centered rather than learner-centered pedagogy. The meaningful application of this latter set of principles or epistemological gradients comprises the 'learning up' situation whose structure is excunined in some détail and considered from various perspectives in the ensuing.

Language use and language attitudes in Malawian universities

This study aims to investigate patterns of language use and language attitudes amongst students in Malawian universities. This will highlight whether language issues affect Malawians’ ability to engage with tertiary education. It has been claimed that ineffective language policies in developing countries restrict people’s ability to access systems such as education. As a result, this has a negative impact on their own, and their country's, development. Specifically, Malawi frequently has the lowest rates of university enrolment worldwide and is consistently ranked amongst the world’s poorest countries. Recent language policy changes within Malawi have brought the issue of language use within education to the fore, with increased debate over whether English or indigenous languages are suitable for use in education. Through targeting university students across Malawi’s universities using semistructured interviews, data was collected to illustrate aspects of the sociolinguistic situation within Malawian universities. The results reveal that both English and indigenous languages are used within the university environment, while also suggesting that issues do arise from language use within university. While students recognise both positive and negative aspects of using each language, they are generally more favourable towards the use of English as a medium of instruction within university

A Cavalaria Portuguesa e as Missões de Paz : Reflexos da mudança da Arte Militar

O Exército Português tem projetado contingentes para participar em Missões de Paz sob e égide das principais Organizações Internacionais. Estas missões, pela sua complexidade exigiram das instituições militares a capacidade de atuar em conflitos em que as entidades desestabilizadoras se encontram no seio da população. O presente trabalho está subordinado ao tema: “A Cavalaria Portuguesa e as Missões de Paz – Reflexos da Mudança da Arte Militar” e o objectivo desta investigação é compreender as alterações efetuadas nas Unidades de Cavalaria projetadas em Operações de Apoio à Paz no Teatro de Operações do Kosovo. A metodologia utilizada para a realização do mesmo foi feita através do método indutivo, em que foi feito um estudo de caso baseado em Unidades de Cavalaria projetadas em Operações de Apoio à Paz no Teatro de Operações do Kosovo, com o objetivo de formular ideias e princípios a serem utilizados no Exército Português quer no mesmo teatro, quer em outros. A recolha de informação surgiu da análise documental e de algumas entrevistas feitas a militares que participaram em missões no Teatro de Operações do Kosovo. Os resultados espelharam que as mais notáveis alterações a nível orgânico, de instrução e treino e de emprego de viaturas blindadas no teatro refletiram-se sobretudo pela integração na Reserva Tática do Kosovo Force e consequentemente pela gradual pacificação do conflito.

Prevalencia del síndrome metabólico en el adulto mayor en las parroquias urbanas del cantón Cuenca, 2015

Introducción: En la actualidad existe un incremento de la población adulta mayor en el Ecuador, donde las tres principales causas de muerte son: diabetes, enfermedades hipertensivas, enfermedades cerebrovasculares. Las mismas que se relacionan etiopatológicamente con el síndrome metabólico. Objetivo: Determinar la prevalencia del síndrome metabólico (SM) en adultos mayores en el cantón Cuenca, 2015. Método y materiales: Se trata de un estudio descriptivo, que se realizó en 387 adultos de ambos sexos mayores de 65 años, en las parroquias urbanas del cantón Cuenca. Se excluyó a los adultos mayores con deficiencia mental, alteraciones del estado de conciencia, impedimento físico o con evidencia de diabetes. Para el levantamiento de los datos se utilizó una encuesta y se realizó pruebas de glicemia en ayunas, colesterol, triglicéridos, lípidos de alta densidad (HDL, high density lipids) y medidas antropométricas, los datos obtenidos fueron analizados estadísticamente mediante EpiInfo, Microsoft Excel 2010 y el software SPSS, y se presentó mediante tablas y gráficos de estadística descriptiva de porcentajes y frecuencias.

Les facteurs affectant les taux de réussite des cours d’anglais et de sciences humaines des étudiants dans les programmes de formation technique

A large percentage of Vanier College's technology students do not attain their College degrees within the scheduled three years of their program. A closer investigation of the problem revealed that in many of these cases these students had completed all of their program professional courses but they had not completed all of the required English and/or Humanities courses. Fortunately, most of these students do extend their stay at the college for the one or more semesters required for graduation, although some choose to go on into the workforce without returning to complete the missing English and/or Humanities and without their College Degrees. The purpose of this research was to discover if there was any significant measure of association between a student's family linguistic background, family cultural background, high school average, and/or College English Placement Test results and his or her likelihood of succeeding in his or her English and/or Humanities courses within the scheduled three years of the program. Because of both demographic differences between 'hard' and 'soft' technologies, including student population, more specifically gender ratios and student average ages in specific programs; and program differences, including program writing requirements and types of practical skill activities required; in order to have a more uniform sample, the research was limited to the hard technologies where students work hands-on with hardware and/or computers and tend to have overall low research and writing requirements. Based on a review of current literature and observations made in one of the hard technology programs at Vanier College, eight research questions were developed. These questions were designed to examine different aspects of success in the English and Humanities courses such as failure and completion rates and the number of courses remaining after the end of the fifth semester and as well examine how the students assessed their ability to communicate in English. The eight research questions were broken down into a total of 54 hypotheses. The high number of hypotheses was required to address a total of seven independent variables: primary home language, high school language of instruction, student's place of birth (Canada, Not-Canada), student's parents' place of birth (Both-born-in-Canada, Not-both-born-in-Canada), high school averages and English placement level (as a result of the College English Entry Test); and eleven dependent variables: number of English completed, number of English failed, whether all English were completed by the end of the 5th semester (yes, no), number of Humanities courses completed, number of Humanities courses failed, whether all the Humanities courses were completed by the end of the 5th semester (yes, no), the total number of English and Humanities courses left, and the students' assessments of their ability to speak, read and write in English. The data required to address the hypotheses were collected from two sources, from the students themselves and from the College. Fifth and sixth semester students from Building Engineering Systems, Computer and Digital Systems, Computer Science and Industrial Electronics Technology Programs were surveyed to collect personal information including family cultural and linguistic history and current language usages, high school language of instruction, perceived fluency in speaking, reading and writing in English and perceived difficulty in completing English and Humanities courses. The College was able to provide current academic information on each of the students, including copies of college program planners and transcripts, and high school transcripts for students who attended a high school in Quebec. Quantitative analyses were done on the data using the SPSS statistical analysis program. Of the fifty-four hypotheses analysed, in fourteen cases the results supported the research hypotheses, in the forty other cases the null hypotheses had to be accepted. One of the findings was that there was a strong significant association between a student's primary home language and place of birth and his or her perception of his or her ability to communicate in English (speak, read, and write) signifying that both students whose primary home language was not English and students who were not born in Canada, considered themselves, on average, to be weaker in these skills than did students whose primary home language was English. Although this finding was noteworthy, the two most significant findings were the association found between a student's English entry placement level and the number of English courses failed and the association between the parents' place of birth and the student's likelihood of succeeding in both his or her English and Humanities courses. According to the research results, the mean number of English courses failed, on average, by students placed in the lowest entry level of College English was significantly different from the number of English courses failed by students placed in any of the other entry level English courses. In this sample students who were placed in the lowest entry level of College English failed, on average, at least three times as many English courses as those placed in any of the other English entry level courses. These results are significant enough that they will be brought to the attention of the appropriate College administration. The results of this research also appeared to indicate that the most significant determining factor in a student's likelihood of completing his or her English and Humanities courses is his or her parents' place of birth (both-born-in-Canada or not-both-born-in-Canada). Students who had at least one parent who was not born in Canada, would, on average, fail a significantly higher number of English courses, be significantly more likely to still have at least one English course left to complete by the end of the 5th semester, fail a significantly higher number of Humanities courses, be significantly more likely to still have at least one Humanities course to complete by the end of the 5th semester and have significantly more combined English and Humanities courses to complete at the end of their 5th semester than students with both parents born in Canada. This strong association between students' parents' place of birth and their likelihood of succeeding in their English and Humanities courses within the three years of their program appears to indicate that acculturation may be a more significant factor than either language or high school averages, for which no significant association was found for any of the English and Humanities related dependent variables. Although the sample size for this research was only 60 students and more research needs to be conducted in this area, to see if these results are supported with other groups within the College, these results are still significant. If the College can identify, at admission, the students who will be more likely to have difficulty in completing their English and Humanities courses, the College will now have the opportunity to intercede during or before the first semester, and offer these students the support they require in order to increase their chances of success in their education, whether it be classes or courses designed to meet their specific needs, special mentoring, tutoring or other forms of support. With the necessary support, the identified students will have a greater opportunity of successfully completing their programs within the scheduled three years, while at the same time the College will have improved its capacity to meeting the needs of its students.

Exploring the influence of a science content course incorporating explicit nature of science and argumentation instruction on preservice primary teachers' views of nature of science

There exists a general consensus in the science education literature around the goal of enhancing students. and teachers. views of nature of science (NOS). An emerging area of research in science education explores NOS and argumentation, and the aim of this study was to explore the effectiveness of a science content course incorporating explicit NOS and argumentation instruction on preservice primary teachers. views of NOS. A constructivist perspective guided the study, and the research strategy employed was case study research. Five preservice primary teachers were selected for intensive investigation in the study, which incorporated explicit NOS and argumentation instruction, and utilised scientific and socioscientific contexts for argumentation to provide opportunities for participants to apply their NOS understandings to their arguments. Four primary sources of data were used to provide evidence for the interpretations, recommendations, and implications that emerged from the study. These data sources included questionnaires and surveys, interviews, audio- and video-taped class sessions, and written artefacts. Data analysis involved the formation of various assertions that informed the major findings of the study, and a variety of validity and ethical protocols were considered during the analysis to ensure the findings and interpretations emerging from the data were valid. Results indicated that the science content course was effective in enabling four of the five participants. views of NOS to be changed. All of the participants expressed predominantly limited views of the majority of the examined NOS aspects at the commencement of the study. Many positive changes were evident at the end of the study with four of the five participants expressing partially informed and/or informed views of the majority of the examined NOS aspects. A critical analysis of the effectiveness of the various course components designed to facilitate the development of participants‟ views of NOS in the study, led to the identification of three factors that mediated the development of participants‟ NOS views: (a) contextual factors (including context of argumentation, and mode of argumentation), (b) task-specific factors (including argumentation scaffolds, epistemological probes, and consideration of alternative data and explanations), and (c) personal factors (including perceived previous knowledge about NOS, appreciation of the importance and utility value of NOS, and durability and persistence of pre-existing beliefs). A consideration of the above factors informs recommendations for future studies that seek to incorporate explicit NOS and argumentation instruction as a context for learning about NOS.

Militarising the body politic : new media as weapons of mass instruction

As militarization of bodies politic continues apace the world over, as military organizations again reveal themselves as primary political, economic and cultural forces in many societies, we argue that the emergent and potentially dominant form of political economic organization is a species of neo-feudal corporatism. Drawing upon Bourdieu, we theorize bodies politic as living habitus. Bodies politic are prepared for war and peace through new mediations, powerful means of public pedagogy. The process of militarization requires the generation of new, antagonistic evaluations of other bodies politic. Such evaluations are inculcated via these mediations, the movement of meanings across time and space, between formerly disparate histories, places, and cultures. New mediations touch new and different aspects of the body politic: its eyes, its ears, its organs, but they are consistently targeted at the formation of dispositions, the prime movers of action.
