No. of bitstreams: 1 Walquiria de Jesus Ribeiro.pdf: 1179237 bytes, checksum: 226dd5d8500031ff1bfbecf3cc0c440e (MD5) Previous issue date: 2013-02-18 / Pontif?cia Universidade Cat?lica de Campinas / The high ability/giftedness is a multidimensional phenomenon, whose evaluation has become a challenge nowadays, especially when it considers the lack of standardized and validated instruments in Brazil for this purpose. This study aimed to look for evidence of validity (construct and criterion) of a Battery for Assessment of High Ability. The sample was composed of students of the 2nd. year of elementary school to 3rd. year of high school, of both sexes, average age eleven (SD=2,02), divided into 470 students in regular education and 118 students participating in the Student Support Services Program with High Ability. The instrument used was composed of six subtests, four of reasoning (verbal, abstract, numerical and logical) one of figural creativity (Completing figures) and other verbal creativity (Creating Metaphors). Through exploratory factor analysis, we found three factors with eigenvalues of 3.737, 1.535 and 1.093, explaining 70.72% of the total variance, with Factor 1 representing measures Verbal Creativity; Factor 2, Intelligence; and Factor 3, Creativity figural. Correlations were found between the factors, more moderate, between Creativity and Intelligence Verbal (r=0.346). Significant effects of the variable group were noted in relation to evidence RV, RA, RN and RL, as well as factor in test preparation Figural Creativity and Quality characteristic Metaphorical Verbal Creativity Test, demonstrating discriminatory power of these measures in the identification of students with high skills. The results showed evidence of construct validity Battery for Assessment of High Ability in assessing Intelligence, Creativity Figural and Verbal and evidence of criterion validity for identifying high ability students from the subtests of intelligence, and partially through some measures of verbal and figural creativity. Other studies are needed to further investigate the psychometric criteria of the instrument under construction. / As altas habilidades/superdota??o ? um fen?meno multidimensional, cuja avalia??o tem se tornado um desafio nos dias atuais, ainda mais quando se constata a falta de instrumentos validados e normatizados no Brasil para tal fim. Este estudo teve como objetivo buscar evid?ncias de validade (construto e crit?rio) de uma Bateria para Avalia??o das Altas Habilidades. A amostra total foi composta por 588 alunos do 2?. ano do ensino fundamental ao 3?. ano do ensino m?dio, de ambos os sexos, m?dia de idade de 11,11 anos (DP=2,02), divididos em 470 alunos de sala de ensino regular e 118 alunos participantes de Programa de Atendimento ao Aluno com Altas Habilidades. O instrumento utilizado foi composto por seis subtestes, sendo quatro de racioc?nio (Racioc?nio verbal, abstrato, num?rico e l?gico), um de criatividade figural (Completando figuras) e outro de criatividade verbal (Cria??o de Met?foras). Atrav?s da an?lise fatorial explorat?ria, foram encontrados tr?s fatores com eigenvalues de 3,737; 1,535 e 1,093, explicando 70,72% da vari?ncia total, com o Fator 1 representando medidas de Criatividade Verbal, o Fator 2, de Intelig?ncia e o Fator 3, de Criatividade Figural. Correla??es foram encontradas entre os fatores, de forma mais moderada, entre Criatividade Verbal e Intelig?ncia (r=0,346). Efeitos significativos da vari?vel grupo foram notados em rela??o ?s provas RV, RA, RN e RL, bem como no fator Elabora??o no teste de Criatividade Figural e na caracter?stica Qualidade Metaf?rica do teste de Criatividade Verbal, demonstrando poder discriminat?rio dessas medidas na identifica??o dos alunos com altas habilidades. Os resultados apontaram evid?ncias de validade de construto da Bateria para Avalia??o das Altas Habilidades na avalia??o da Intelig?ncia, Criatividade Figural e Verbal e evid?ncias de validade de crit?rio para identifica??o de alunos com altas habilidades a partir dos subtestes de intelig?ncia, e, parcialmente, atrav?s de algumas medidas de criatividade figural e verbal. Outros estudos se fazem necess?rios para melhor investiga??o dos crit?rios psicom?tricos do instrumento em constru??o.

No. of bitstreams: 1 Janete Tonete Suarez.pdf: 3648120 bytes, checksum: 70000b5a6a9c28d53162eb70b92c10b2 (MD5) Previous issue date: 2014-02-26 / The process of identifying talent/giftedness with a view to educational services requires knowledge and appropriate resources. In order to reduce barriers to talent identificationhas been increasing a growing demand for trained teachers and valid measurement instruments. Given this context, this study aimed to identify creative and intellectual talent in the classroom from three instruments: Evaluation Battery Intelligence and Creativity - Children's version (BAICI), in validation process; Non Verbal Child Reasoning Test (TNVRI) already validated in Brazil, and their perception of teachers obtained from the scale entitled Talent Identification by Professor (ITP). Four studies were proposed: 1. The development of the Talent Identification scale by the teacher; 2. Identification of intellectual and creative talents by the Professor; 3. Identification of creative and intellectual talents by psychological tests, and finally, 4. Evidence of validity by way of external criterion between the Battery (BAICI) and the Teste (TNVRI), and between Battery (BAICI) and the scale (ITP). The study sample was composed of four judges, 10 professors and 120 students from the 4th and 5th year of elementary school, two private schools in the metropolitan region of Campinas, SP. The age of participants ranged from 9 to 10 years of which 62 were females and 58 males. The results for each study were as follows: 1. The coefficient of Content Validity (CVC) of ITP instrument was 0.82, considered positive. 2. The teacher seems to notice more female talent for the highest averages in all areas. However, the hypothesis of gender equality should be rejected only for the Memory subscale in ITP. 3. Gender was not significant in any subtest of BAICI including verbal and figural creative skills. The same was found with TNVRI reinforcing the hypothesis of absence of significant cognitive gender differences. 4. There was correlation between the various subtests of BAICI. The highest of these was between the visual memory subtest and overall cognitive index. As to the evidence of validity by way of external criterion between BAICI and TNVRI, it was noticed a significant correlation between subtest only for the fast thinking. The values of Cronbach's alpha were 0.83 and 0.75 for the ITP and BAICI, demonstrating the accuracy of results. Students who scored above average in psychological instruments were identified through a qualitative - comparative analysis of students, but these same students were not identified by their teachers. We conclude that education should pay attention to the training of teachers so that they understand the different abilities present in the classroom and promote actions aimed at its development from varied and combined procedures. / O processo deidentificacao do talento/superdotacao com vistas ao atendimento educacional exigeconhecimento e recursos apropriados. Tem sido cada vez maior a demanda por professores capacitados e instrumentos validos de medida a fim de diminuir os obstaculos que impedem a identificacao do talento. Diante deste contexto, este estudo objetivou identificar talentos criativos e intelectuais na sala de aula a partir de tres instrumentos: Bateria de Avaliacao da Inteligencia e Criatividade forma Infantil (BAICI), em processo de validacao; Teste Nao Verbal de Raciocinio Infantil (TNVRI), ja validado no Brasil; e a percepcao dos professores obtida a partir da escala intitulada Identificacao de Talentos pelo Professor (ITP). Quatro Estudos foram propostos: 1. Elaboracao da escala Identificacao de Talentos pelo professor; 2. Identificacao de talentos intelectuais e criativos pelo professor; 3. Identificacao de talentos criativos e intelectuais por testes psicologicos; e finalmente,4. Evidencias de validade por forma de criterio externo entre BAICI e TNVRI, e entre BAICI e ITP. A amostra do estudo foi composta por quatro juizes avaliadores, 10 professorese 120 estudantes do 4.o e 5.o anos do Ensino Fundamentalde duas escolas particulares da regiao metropolitana de Campinas SP. A idade dos participantes variou dos 9 aos 10 anos dos quais 62 eram do genero feminino e 58masculino. Os resultados referentes a cada estudo foram os seguintes: 1. O Coeficiente de Validade do Conteudo (CVC) do instrumento ITP foi de 0,82, considerado positivo. 2. Oprofessor parece perceber mais o talento feminino pelas medias mais altasem todas as areas. No entanto, a hipotese de igualdade de genero deve ser rejeitada apenas para a subescala Memoria no ITP. 3. O genero nao se mostrou significativo em nenhum subteste da BAICI, incluindo as habilidades criativas verbais e figurais. O mesmo foi verificado com o TNVRI reforcando a hipotese de nao existencia de diferenca cognitiva significativa entre os generos. 4. Houve diversas correlacao entre os subtestes da BAICI. A mais alta delas foi entre o subteste memoria visual e indice cognitivo total. Quanto as evidencias de validade por forma de criterio externo entre BAICI e TNVRI, percebeu-se haver correlacao significativa somente entre o subteste rapidez de raciocinio. Os valores de alfa de Cronbach foram 0,83 e 0,75 para o ITP e BAICI, demonstrando a precisao dos resultados encontrados. Atraves de uma analise qualitativa/comparativa foram identificados estudantes que pontuaram acima da media nos instrumentos psicologicos, porem nao identificados por seus professores. Conclui-se que a educacao deve atentar para a capacitacao de professores a fim de que estes conhecam as diferentes habilidades presentes na sala de aulas e promovam acoes dirigidas para seu desenvolvimento a partir de procedimentos variados e combinados.

Elabora??o de instrumento para identifica??o de alunos intelectualmente dotados por professores: estudo explorat?rio / Development of instrument for identifying intellectually gifted students for teachers: an exploratory study

Farias, Eliana Santos de 27 February 2012 (has links)
Made available in DSpace on 2016-04-04T18:29:57Z (GMT). No. of bitstreams: 1 Eliana Santos de Farias.pdf: 1151108 bytes, checksum: d8a60100a4bf3e58e4d3db0ecf8a6ca5 (MD5) Previous issue date: 2012-02-27 / The identification of students fitted and / or talent is characterized by a variety of possibilities. This identification may be multidimensional (areas, dimensions), multireferential (parents, teachers, psychologists and other staff), multi-method (methods, processes, tools), multi-temporal (time, stages of development), multi-contextual (tasks at school, at home and others), and multi-stage (stages or modules support). In this case, the figure of the teacher deserves, and effective participation through teacher nomination. In Brazil, there is no instrument with a favorable recommendation by the Federal Council of Psychology. Given this fact, the objective is to develop two studies, the first draw up a scale of appointing teachers for gifted and talented students as well as search for evidence of content validity, where as the second study, we sought evidence for the consistency of accuracy internal and validity based on internal structure and convergent and discriminant. After formulating the instrument (ENDI-p), the results of the first study indicate that the ENDI-p is ready for use, when looking at the kappa coefficient (km?dio= 0.778). The ENDI-p lost five items and had four items adapted to other areas other than the original. In the second study, by means of item-total correlation were removed 17 items from Endi-p showed that saturation index less than 0.30 (varimax rotation) which resulted in three major factors. With the removal of such items, the scale was a good value for the overall Cronbach's alpha (alfa= 0.801), but also for the three specific factors: F1 (alfa=0.892 with 23 items), F2 (alfa= 0.929 with 26 items), F3 (alfa= 0.727 with 7 items), given the goal 3. The Bartlett test of sphericity indicated a correlation between items (x2 0=4370,985; gl=1653; p<0,000). Since the measure of sampling adequacy for the application of factor analysis showed to be appropriate for the test of Kaiser-Meyer-Olkin (KMO = 0.498). The fourth objective was met through exploratory factor analysis (EFA) resulting in three factors. Objectives 5 and 6, about the search for evidence of validity based on relationships with external variables were partially met, which may suggest, for future studies using a larger sample. / A identifica??o de alunos dotados e/ou talentosos caracteriza-se por uma diversidade de possibilidades. Esta identifica??o pode ser multidimensional (?reas, dimens?es), multireferencial (pais, professores, psic?logos e outros agentes), multi-m?todo (meios, processos, instrumentos), multi-temporal (momentos, est?gios do desenvolvimento), multi-contextual (tarefas na escola, em casa e outros) e, multi-et?pica (fases ou m?dulos de apoio). Neste processo, a figura do professor merece destaque, e efetiva sua participa??o por meio de nomea??o docente. No Brasil, ainda n?o existe instrumento com recomenda??o favor?vel pelo Conselho Federal de Psicologia. Diante deste fato, objetivou-se por desenvolver dois estudos, no primeiro elaborar uma escala de nomea??o docente para alunos dotados e talentosos, bem como buscar por evidencias de validade de conte?do; j? no segundo estudo, buscou-se por evidencias de precis?o da consist?ncia interna, bem como validade baseada na estrutura interna e convergente e discriminante. Depois de elaborado o instrumento (ENDI-p), os resultados do primeiro estudo indicam que a ENDI-p est? pronta para uso, ao se observar o coeficiente de kappa (km?dio=0,778). A ENDI-p perdeu cinco itens e teve quatro itens adaptados para outras ?reas, que n?o as originais. No segundo estudo, por meio da correla??o item-total foram retirados 17 itens da ENDI-p que apresentaram ?ndices de satura??o inferiores a 0,30 (rota??o varimax) o que resultou em tr?s grandes fatores. Com a extra??o destes itens, a escala apresentou um bom valor para o Alpha de Cronbach geral (alfa=0,801), como tamb?m para os tr?s fatores espec?ficos: F1 (alfa=0,892 com 23 itens), F2 (alfa=0,929 com 26 itens), F3 (alfa=0,727 com 7 itens), atendendo ao objetivo 3. O teste de esfericidade de Bartlett indicou correla??o entre os itens (x2 0=4370,985; gl=1653; p<0,000). J? a medida de adequa??o da amostra para aplica??o da an?lise fatorial apresentou-se apropriada pelo teste de Kaiser-Meyer-Olkin (KMO=0,498). O quarto objetivo foi atendido por meio da an?lise fatorial explorat?ria (AFE) resultando em tr?s fatores. Os objetivos 5 e 6, a respeito da busca de evidencias de validade baseadas nas rela??es com vari?veis externas foram parcialmente atendidos, o que pode sugerir, para futuros estudos utilizar uma amostra maior.
