Ensino de ciências e educação moral: uma interface de implicações mútuas

Nas teorias sociomorais que perpassam Piaget, Kohlberg e Habermas, encontramos subsídios para o ensino de Ciências que se estabelece na perspectiva da construção crítica do conhecimento e da desmistificação da visão de ciência, assim como, de forma correspondente, também encontramos nos pressupostos do ensino crítico e desmistificado de Ciências um conjunto de subsídios que potencializa o desenvolvimento moral e a dimensão ética discursiva. Neste artigo, compartilhamos com o leitor alguns de nossos argumentos em prol da existência dessa ainda subestimada interface de implicações mútuas entre Ensino de Ciências e Educação Moral, com a presença de relevantes subsídios teórico-práticos que uma área pode dar à outra. A expectativa é que as discussões apresentadas contribuam para a reflexão do trabalho docente, numa perspectiva de educação científica e moral baseada no processo de construção da autonomia do aluno.

Características da interface dos sites de notícias: um estudo do design e da usabilidade de jornais impressos e eletrônicos

The paper presents an ergonomic analysis of reading usability of electronic journals and the comparison with newspapers. As a method, it was adopted an evaluation of the user perception, from a printed questionnaire applied to a group of 41 people. Overall, the results indicate that on the analyzed newspapers there is need for greater care concerning the aspects of visual representation, involving more design application, usability, ergonomics, technology and communication.

Desempenho de crianças com deficiência auditiva e implante coclear em tarefas de seleção de e de nomeação de figuras

The aim of this study was to investigate the development of specific domains of Numerical Cognition (Number Sense – NS, Number Comprehension – NC, Number Production – NP, and Calculation – CA) in Brazilian children with Specific Learning Disorders. The study included 72 children (36 boys), from 9-to 10-years-old, enrolled in 4th and 5th years of elementary school of public schools at countryside of Sao Paulo State, Brazil. They were divided into three groups: control (CT, N = 42), Developmental Dyslexia (DL, N = 11) and Developmental Dyscalculia combined with dyslexia (DDc, N = 19). All participants had intellectual level within the normal range, however, children from the last two groups had Learning Disorders classified by School Achievement Test - TDE (Stein, 1994) and DDc children received necessarily classification as 'inferior' in Arithmetic Test of TDE. The children did not differ in NS. DL and DDc children showed slight deficits in NC. However, DDc children had moderate in NP and mild to moderate deficits in CA, which indicates a more generalized impairment in Numerical Cognition. Furthermore, DDc children showed discrepancy in Numerical Cognition performance when compared to the other groups. Thus, children with Learning Disorders showed different performances in Numerical Cognition, although both groups had preserved SN, DDc children showed higher deficits and discrepancy in relation DL and typically developing children.

Aprendizagem após via exclusão e formação de classes de equivalência em crianças com deficiência auditiva e implante coclear (aceito condicionalmente)

Studies on learning by exclusion have shown that participants tend to select a new object or a new figure when a new word is dictated, rejecting the objects and figures they already know or that were associated with other words. This study aimed at training conditional relations between dictated word-picture and between picture-printed word, by exclusion, and verify whether this training would be a condition for the emergence of relations between dictated word-printed word, printed word-figure, picture naming and reading. We also investigated whether responding to the words dictated with a female voice generalized to other frequencies such as male and child voices. Participants were five children between five and nine years old, with acute neurosensorial bilateral hearing impairment, users of cochlear implant Nucleus 24k®. They were exposed, individually, to tasks that consisted in selecting a comparison stimulus (either picture or printed word) related to the sample (either dictated word or picture). Words with lowest scores on a pre-test were used. The relations between dictated word-figure (AB) and figure-printed word (BC) were taught by exclusion. We assessed the emergence of the relations between dictated and printed words (AC), printed word and picture (CB), male and child voices generalization (A’C and A’’C), naming (BD) and reading (CD). All the children responded by exclusion and learned relations AB and BC, showing receptive vocabulary; AC and CB relations also were learned, consistent with class formation. Responding generalized to male and child voices, but data on naming were not systematic. Learning by exclusion was similar to that of children with typical hearing and these results describe some conditions that can improve receptive verbal repertoire.

Uma proposta de formação continuada de professores de ciências e matemática na interface do agir comunicativo e das questões sociocientíficas

The objective of this paper is to present a theoretical proposal for the training of teachers of mathematics and science at the interface of communicative action and socio-scientific issues. In this paper we argue for the need for a continuous training of teachers if we are to be interested in developing the scientific training of students from the public school system. To form communicatively competent students, by the end of schooling, becomes necessary the training of argumentatively competent teachers. Therefore, we believe that the theory of communicative action by Jurgen Habermas, will cooperate to this end.

Ecóico e nomeação de figuras em crianças com deficiência auditiva pré-lingual com implante coclear

The aim of this work was to verify the effect of teaching the echoic behavior over the pictures naming in four children between eight and nine years old with prelingual hearing impaired, users of cochlear implants. The design adopted was: (a) pre-training that taught the matching-to-sample task; (b) pre-tests that selected three words to teach; (c) teaching of auditory-visual conditional relations; (d) naming pos-test; (e) the teaching of echoic with orofacial clues and, (f) the second naming pos-test. In the pre-test all participants achieved smaller percentage of correct on naming (60%-80%) and echoic (20%-50%) when compared to percentages word recognition (86%-93%). All participants learned the auditory-visual relations. The improvement on naming test occurred after auditory training select based for two participants; for other two participants the improvement on naming test occurred just after the training of echoic. Analysis of data showed that the listening and speaking performances are independent in their establishment and require specific conditions of teaching; in the case of this study, even though the result is not generalized to all participants, the highest correspondence into point to point naming was obtained following the teaching of echoic.

Problemas ergonômicos enfrentados por profissionais de enfermagem em ambientes hospitalares: aspectos da interface trabalhadores x equipamentos

The ergonomic design seeks to establish parameters to improve the interface between the technologies (products, systems and environments) and between man (users). Among the many factors involved, there are the activities performed in hospital settings, both by patients and by clinical staff. Accordingly, efforts have been demonstrated biomechanical with a leading occupational problem, especially regarding the transfer of patients.

Bond strength and Raman analysis of the zirconia-feldspathic porcelain interface

The test groups were experimental zirconia, Zirkonzahn zirconia, and Schuetz zirconia. Blocks of partially sintered zirconia were cut into disks (n=20) and then veneered with a feldspathic porcelain. Half of the specimens from each group (n=10) were incubated in 37°C water for 24 hours, and the other half were thermocycled. All the specimens were then subjected to shear testing. The fractured areas were analyzed with optical stereomicroscopy and classified as adhesive, cohesive, or an adhesive-cohesive failure. Spectral patterns were examined to detect bands related to the zirconia and feldspathic porcelain phases. The shear strength data were submitted to 2-way ANOVA. Results No significant differences in shear bond strength were observed among the 3 groups, regardless of whether or not the specimens were thermocycled. Adhesive failures were the most prevalent types of failure (70%). Raman spectra were clearly distinguished for all the materials, which showed the presence of tetragonal and monoclinic phases. Conclusions The controlled production of the experimental zirconia did not influence the results of the bond strength. Raman analysis suggested a process of interdiffusion by the presence of peaks associated with the zirconia and feldspathic ceramics.
