No. of bitstreams: 1 CAROLINA ROSA CAMPOS.pdf: 3585459 bytes, checksum: ff8320df856df1f736a4caeeb06da635 (MD5) Previous issue date: 2017-02-13 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Considering the importance of the inclusion of the visually impaired regarding issues investigated by Psychology, this research had the objective of continuing a process of building a battery to assess cognitive abilities of visually impaired children. The instrument, consisting of four subtests (verbal reasoning, logical, numerical and memory) which belong to the Intelligence Assessment Battery for Visually Impaired Children (PAIC-DV) and the scale of Teacher?s Perception of Visually Impaired Children?s Intelligence (EPIC-DV), was the target of a series of studies aiming for the investigation of its psychometric qualities. Different samples were used to achieve these goals: 195 children, with 30 visually impaired (type: acquired n = 8; congenital n = 12; degree: low vision n = 23; blindness n = 7) aged between seven and 12 years (M = 9.76; DP = 1.81) and 165 normal vision children, aged between seven and 12 years (M = 11.57; DP = 0.41); 15 teachers, with 10 specialized in service to the visually impaired and 5 regular education teachers, which responded to scale evaluating each of the 195 children. The results of the PAIC-DV pointed to psychometric suitability of the instrument?s factorial structure, inside a model with second-order factor (General Intelligence) and three specific factors related to the subtests Verbal Reasoning, Logical and Numeric (the Memory subtest was not inserted in the analysis). Significant differences were also found related to total scores of each subtest within the group, and normal vision children showed better results in all subtests when compared to children with visual impairment. Significant positive correlations were found in moderate magnitude and weak for most of the results in the comparison between PAIC-DV and BPR-5, as well as between the PAIC-DV and school grades and levels of internal consistency amongst 0.85 and 0.88 for each factor, indicating good precision of the instrument. EPIC-DV results showed content evidence validity through the analysis of judges and construct validity evidence by means of a model with second-order factor (General Intelligence) and four specific factors related to the subtests Verbal Reasoning, Logical, Numerical and Memory. Significant differences were found regarding the performance subtests at all, with the exception of numerical reasoning. The evaluations carried out by the teachers showed better performance of children with visual impairment in all factors (with the exception of numerical reasoning), compared to the evaluations carried out for normal vision children. Regarding the type of disability, a significant difference was found only for verbal reasoning, with better performance of children with congenital deficiency and, in relation to the degree, no significant differences were found for any factor. Considering school grades, few correlations and low magnitude have been found. The reliability, by means of internal consistency ranged from 0.94 to 0.97 for each factor, indicating good accuracy of the instrument. Supplementary analysis made through the investigation of convergent validity evidence, used the BPR-5 that indicated significant negative correlations and weak magnitude from the PAIC-DV with Logical Reasoning and Numerical Reasoning, as well as of the total score of the EPIC-DV with Numerical Reasoning test. Finally, congruence analysis was applied concerning the instruments that structure the battery, whose results indicated significant correlations as moderate positive and weak among the instruments, indicating the possibility that both are used as complements when assessing cognitive aspects of children with visual impairment. We conclude that the studies developed with the instruments brought relevant data about the importance of a specific intelligence assessment instrument for children with visual impairment, and studies with larger samples can enrich and contribute to the expansion in use of the built instrument. / Teniendo en cuenta la importancia de la inclusi?n de la discapacidad visual en las cuestiones investigadas por la psicolog?a, esta investigaci?n tuvo como objetivo continuar con el proceso de construcci?n de una bater?a de pruebas para evaluar las capacidades cognitivas de los ni?os con discapacidad visual. El instrumento consta de cuatro pruebas de rendimiento (razonamiento verbal, l?gico, num?rico y memoria) que pertenece a la Bater?a de Evaluaci?n de Inteligencia para ni?os con discapacidad visual (PAIC-DV) y la Escala de Percepci?n de Maestros acerca de la inteligencia de ni?os con discapacidad visual (EPIC -DV), que fue objeto de una serie de estudios para investigar sus cualidades psicom?tricas. Diferentes muestras se utilizaron para alcanzar estas metas: 195 ni?os, 30 discapacitados visuales (tipo: Adquirida n = 8; cong?nita n = 12; grado: baja visi?n n = 23; ceguera n = 7) con edades comprendidas entre siete y 12 a?os ( M = 9.76, SD = 1.81) y 165 ni?os videntes, con edades comprendidas entre siete y 12 a?os (M = 11,57, SD = 0,41); 15 profesores, 10 especializados en el servicio a personas con discapacidad visual y 5 maestros de escuelas regulares, que respondieron a la escala de evaluaci?n de cada uno de los 195 ni?os. Los resultados de la PAIC-DV se?alaron adecuaci?n psicom?trica de la estructura factorial del instrumento dentro de un modelo con un factor de segundo orden (inteligencia general) y tres factores espec?ficos relacionados con las pruebas de razonamiento verbal, l?gico y num?rico (prueba memoria no fue insertado en el an?lisis). Tambi?n se encontraron diferencias significativas en relaci?n al total de cada prueba en relaci?n con el grupo. Los ni?os con visi?n han obtenido mejores resultados en todas las pruebas en comparaci?n con los ni?os con discapacidad visual. En cuanto al tipo de discapacidad, no se encontraron diferencias significativas, y s?lo la prueba de la memoria mostr? diferencias significativas a favor de los ni?os con baja visi?n. Se encontraron correlaciones significativas positivas de magnitud moderada y baja para la mayor?a de los resultados en comparaci?n entre PAIC-DV y BPR-5, as? como entre PAIC-DV y los a?os escolares. Los ?ndices de consistencia interna estuvieron entre 0,85 y 0,88 para cada factor, lo que indica buen instrumento de precisi?n. Los resultados de EPIC-DV mostraron evidencia de la validez de contenido, a trav?s del an?lisis de los jueces y validez de contenido de pruebas por medio de un modelo con un factor de segundo orden (inteligencia general) y cuatro factores espec?ficos relacionados con las pruebas razonamiento verbal, l?gico, num?rico y la memoria. No se encontraron diferencias significativas con respecto al rendimiento en todas las pruebas, excepto por el razonamiento num?rico. La evaluaci?n hecha por los profesores indicaron un mejor rendimiento de los ni?os con discapacidad visual en todos los factores (excepto para el razonamiento num?rico), en comparaci?n con las evaluaciones para los ni?os videntes. En cuanto al tipo de discapacidad, no se encontraron diferencias significativas, s?lo para el razonamiento verbal, con un mejor rendimiento de los ni?os con discapacidad cong?nita y en relaci?n al grado, no hubo diferencias significativas para cualquier factor. En cuanto a los a?os escolares, se encontraron pocas correlaciones y baja magnitud. La precisi?n a trav?s de la consistencia interna vari? de 0,94 a la 0,97 para cada factor, lo que indica buen instrumento de precisi?n. Posterior an?lisis de investigaci?n de validez convergente con la BPR-5 ha indicado correlaciones significativas negativas y de baja magnitud de PAIC-DV con el Razonamiento L?gico y el factor de Razonamiento Num?rico, as? como el total de la EPIC -DV con la prueba de Razonamiento Num?rico. Por ?ltimo, se realiz? un an?lisis de congruencia entre los instrumentos que componen la bater?a y la escala. Los resultados mostraron correlaciones significativas moderadas y d?biles positivas entre los instrumentos de forma que indique la posibilidad de que ambos se utilizan de manera complementaria en la evaluaci?n cognitiva de los ni?os con discapacidades visual. Se concluye que los estudios llevados a cabo con el instrumento trajeron datos relevantes sobre la importancia de un instrumento espec?fico para evaluar la inteligencia de los ni?os con discapacidad visual y que los estudios con muestras m?s grandes pueden enriquecer y contribuir a la expansi?n del uso del instrumento construido. / Considerando a necessidade da inclus?o do deficiente visual nas quest?es investigadas pela Psicologia, bem como a garantia de igualdade nas avalia??es psicol?gicas realizadas, essa pesquisa teve como objetivo a continua??o do processo de constru??o de uma bateria de testes para avalia??o das habilidades cognitivas de crian?as deficientes visuais. O instrumento, composto por quatro subtestes de execu??o (racioc?nio verbal, l?gico, num?rico e mem?ria) pertencentes ? Provas de Avalia??o da Intelig?ncia para Crian?as Deficientes Visuais (PAIC- DV) e pela Escala de Percep??o de Professores da Intelig?ncia de Crian?as deficientes visuais (EPIC-DV), foi alvo de uma s?rie de estudos visando a investiga??o das suas qualidades psicom?tricas. Diferentes amostras foram utilizadas para alcan?ar esses objetivos: 195 crian?as, sendo 30 deficientes visuais (tipo: adquirida n= 8; cong?nita n=12; grau: baixa vis?o n= 23; cegueira n= 7) com idades entre sete e 12 anos (M= 9,76; DP= 1,81) e 165 crian?as normovisuais, com idades entre sete e 12 anos (M= 11,57; DP= 0,41); 15 professores, sendo 10 especializados no atendimento a deficientes visuais e 5 professores de ensino regular, os quais responderam a escala avaliando cada uma das 195 crian?as, assim como um grupo de ju?zes especialistas na ?rea de avalia??o psicol?gica. Os resultados do conjunto PAIC-DV apontaram adequa??o psicom?trica da estrutura fatorial do instrumento, dentro de um modelo com fator de segunda ordem (intelig?ncia geral) e tr?s fatores espec?ficos relacionados aos subtestes Racioc?nio Verbal, L?gico e Num?rico. Foram encontradas diferen?as significativas em rela??o ao total de acertos de cada subteste em rela??o a grupo (crian?as normovisuais apresentaram melhores resultados em todos os subtestes em compara??o com as crian?as com defici?ncia visual), o mesmo n?o ocorrendo em rela??o ao tipo de defici?ncia (somente o subteste de Mem?ria apresentou diferen?as significativas a favor das crian?as com baixa vis?o). Foram encontradas correla??es significativas positivas de magnitude moderada e fraca para a maioria dos resultados na compara??o entre PAIC-DV e BPR-5, bem como entre o conjunto PAIC-DV e as notas escolares, tomados como crit?rio externo. ?ndices de consist?ncia interna entre 0,85 e 0,88 foram encontrados para cada fator, indicando boa precis?o do instrumento. Os resultados da EPIC-DV, por sua vez, apresentaram evid?ncias de validade de conte?do, por meio da an?lise de ju?zes e evid?ncias de validade de construto por meio de um modelo com fator de segunda ordem (intelig?ncia geral) e quatro fatores espec?ficos relacionados aos subtestes Racioc?nio Verbal, L?gico, Num?rico e Mem?ria. Diferen?as significativas em rela??o ao desempenho em todos os subtestes, com exce??o do racioc?nio num?rico, a favor das crian?as com defici?ncia visual em todos os fatores (com exce??o do racioc?nio num?rico). Em rela??o ao tipo de defici?ncia, diferen?a significativa foi encontrada apenas para o racioc?nio verbal, com melhor desempenho das crian?as com defici?ncia cong?nita e, em rela??o ao grau, n?o foram encontradas diferen?as significativas para nenhum fator. Em rela??o ?s notas escolares, poucas correla??es e de baixa magnitude foram encontradas. A precis?o, por meio da consist?ncia interna variou entre 0,94 e 0,97 para cada fator, indicando boa precis?o do instrumento. An?lise complementar, por meio da investiga??o de evid?ncias de validade convergente, usando-se a Bateria de Provas de Racioc?nio 5 indicou correla??es significativas negativas e de magnitude fraca da PAIC-DV com o fator Racioc?nio L?gico e Racioc?nio Num?rico, bem como do Total da EPIC-DV com a prova de Racioc?nio Num?rico. Por fim, foi realizada an?lise de congru?ncia entre os instrumentos que comp?em a bateria, cujos resultados indicaram correla??es significativas positivas moderadas e fracas entre os instrumentos, de modo a indicar a possibilidade de que ambos sejam usados de forma complementar na avalia??o cognitiva de crian?as com defici?ncia visual. Conclui-se que os estudos desenvolvidos com o instrumental trouxeram dados relevantes quanto ? import?ncia de um instrumento espec?fico de avalia??o da intelig?ncia para crian?as com defici?ncia visual e que, estudos com amostras maiores podem enriquecer e contribuir para a expans?o do uso do instrumento constru?do.

Several active learning strategies have been used when increasing the structure of a course as increasing course structure has been known to improve student learning in introductory STEM courses. Much has been studied on the value of frequent formative assessment; however, few studies have evaluated the effective modes of delivering summative assessment. This study examines the use of summative assessment as an inclusive teaching practice to improve first generation college student success in introductory biology and also uses faculty surveys to find out how instructors structure their introductory biology course and why they are structured that way. Final exams were evaluated by Bloom’s Taxonomy of Learning. Survey results showed that many instructors used online activities most of the time to supplement face-to-face courses. However, student and faculty viewpoints on assessments offer many interesting insights into how instructors may modify teaching strategies to increase the success of diverse student populations.

In der vorliegenden Studie wurde sowohl der Einfluss des Schulanteils an Kindern mit einer anderen Muttersprache als Deutsch auf die Sprachleistung (Leseverständnis, Wortschatz und Rechtschreibung) deutschsprachiger Kinder als auch jener des Anteils deutschsprachiger Kinder auf die Sprachleistung von Kindern mit Migrationshintergrund untersucht. Es nahmen 211 Kinder aus der vierten Grundschulstufe, 84 mit Deutsch als Muttersprache (39.8%) und 127 mit einer anderen Muttersprache als Deutsch (60.2%), teil. Kognitive Grundfähigkeiten und der sozioökonomische Hintergrund wurden miterhoben. Die mehrebenenanalytische Auswertung zeigte Effekte der kognitiven Grundfähigkeiten und des sozioökonomischen Hintergrundes auf die Sprachleistung. Die ethnische Zusammensetzung der Schule war nicht bedeutsam. Bei Kindern mit Migrationshintergrund erwies sich der Zeitpunkt des Spracherwerbs als wichtig für die Sprachleistung. Ein möglichst frühzeitiger Erwerb der Sprache des Einwanderungslandes ist daher dringend zu empfehlen. (Autor/inn/enref.) / Series: Discussion Paper Series / Center for Empirical Research Methods

Cette thèse se compose de trois essais sur l’éducation et la cohésion sociale dans les pays en développement, et plus particulièrement en Égypte et en Indonésie. Le premier chapitre analyse les comportements des ménages en Égypte, notamment l’investissement pour l’éducation et la santé, suite à la révolution de 2011, que nous interprétons ici comme un environnement instable. Pour étudier les effets du déclenchement de la révolution Égyptienne, nous combinons l’enquête représentative des ménages avec un enregistrement statistique unique de toutes les personnes arrêtées, blessées ou tuées lors des manifestations politiques dans le pays. Nos résultats montrent que les ménages adaptent considérablement leur comportement dans un contexte politique instable. Le deuxième chapitre analyse les conséquences des tremblements de terre sur l’éducation et les mesures de santé des enfants en Indonésie. Nous constatons que les résultats en matière d’éducation et de santé des enfants sont négativement affectées lorsqu’un ménage subit un tremblement de terre, avec une certaine hétérogénéité selon l’âge et le sexe de l’enfant. Le troisième chapitre analyse les effets du favoritisme ethnique dans l’attribution des transferts gouvernementaux aux ménages suite à une catastrophe naturelle Les résultats suggèrent que bien que tous les ménages d’un même village soient affectées, les ménages les plus susceptibles de recevoir des transferts gouvernementaux sont ceux qui partagent la même origine ethnique que le leader de la communauté. Mes conclusions démontrent également que dans les villages ou le favoritisme ethnique est répandu, la confiance entre groupes ethniques s’est réduite entre 2007 et 2014. / This thesis is a collection of three independent essays in empirical development economics, with a particular focus on the study of mechanisms that impact education and social cohesion in Egypt and Indonesia. The first chapter analyses the effects of the Egyptian Revolution on education and health spendings as well as savings. We construct a new measure of revolution intensity and match a representative household panel survey data with a unique statistical record that documents the number of arrested, injured and deaths during the uprisings in Egypt. We find that households significantly adapt their behaviour in a politically unstable environment. The second chapter analyses the short and long-term effects of earthquakes on children’s education and health outcomes. Findings rely on individual-level panel data from large-scale household surveys combined with precise measures of local ground tremors obtained from a US Geological Survey database. Results suggest that children’s education and health out-comes decrease with some heterogeneity by age and gender. The third chapter identifies ethnic favouritism in the distribution of post-disaster aid at household level in the context of Indonesia. Results show that co-ethnic households are more likely to receive post-disaster relief transfers than households that were equally affected by a natural disaster, but do not share the same ethnicity as the community leader. Results also suggest that ethnic favouritism significantly reduces social cohesion measured by trust in affected communities.Keywords: Education; Health; Cognitive skills; Critical age; Post-disaster aid; Household savings; Trust; Natural disaster; Political instability; Ethnic diversity; Ethnic favouritism; Egypt; Indonesia.

Essa dissertação tem como objetivo analisar o comportamento manipulador relacionado à aplicação de instrumentos de mensuração de competências socioemocionais no ambiente escolar estimulado por duas abordagens que configuram contextos low-stake: o efeito da disseminação da informação sobre essas competências e suas relações com bem-estar e progresso social e da possibilidade dos professores receberem as respostas individuais dos alunos. Para isso, realizou-se um experimento com 2853 alunos de 10 escolas públicas da rede estadual de São Paulo. Os resultados indicam que os alunos são capazes de inflar suas respostas no sentido da desejabilidade social e que as duas abordagens fazem com que os alunos se sintam mais motivados em manipular suas respostas. Além disso, os resultados mostram que a inclusão de uma notificação sobre um mecanismo de detecção de respostas falsas no questionário cria uma barreira e desestimula o comportamento manipulador. / This dissertation aims to examine faking behaviour in personality assessments at schools. Two approaches that create low-stakes environments are investigated: information spreading about non-cognitive skills and their impact on well-being and social progress and the fact that teachers would receive individual students\' answers. Using a CRT technique with 2853 students from 10 São Paulo state public schools, we find that students are capable to fake their answers and these two approaches turn them more motivated to engage in faking. Moreover, we show that a warning about untruthful answers attached to the questionnaire imposes a cost, discouraging faking behaviour

Using a longitudinal panel dataset for a single municipality, we draw the distribution of latent cognitive and non-cognitive factors and consider a dynamic model of skill formation. We find our Constant Elasticity Substitution (CES) production function to be a Cobb-Douglas. The complementarity and share parameters of the CES are stable in diverse specifications tested. We find that early investment matters for cognitive skill accumulation during childhood. Preliminar estimation for long-term cognitive production presents evidence of self-productivity (skill begets skill). Since cognitive skill is persistent overtime, early childhood investment has a positive cumulative impact in the long-term by boosting cognitive skills in earlier stages. / Este trabalho contribui para a literatura de formação de capital humano estimando o impacto do investimento na primeira infância (por meio da frequência pré-escolar) sobre o desenvolvimento de habilidades cognitivas. Usando um painel longitudinal com dados para um único município, extraímos a distribuição dos fatores cognitivo e não-cognitivo e consideramos um modelo dinâmico de formação de habilidades. A função de produção Elasticidade Substituição Constante (CES) que estimamos é uma Cobb-Douglas. Os parâmetros de complementaridade e participação na CES são estáveis para diversas especificações testadas. Encontramos que o investimento na primeira infância é importante para o acúmulo de habilidades cognitivas durante a infância. Estimativas preliminares da função de produção usando medidas de longo prazo para o fator cognitivo apresentam evidências de autoprodutividade (habilidade gera habilidade). Como a habilidade cognitiva é persistente ao longo do tempo, o investimento na primeira infância tem um efeito cumulativo positivo no longo prazo, impulsionando as habilidades cognitivas nos estágios iniciais.

This work deals with the effect the natural environment on the development of motor and cognitive abilities of preschool age. The aim is to determine the effect of education in the natural environment to the level of motor skills and knowledge of preschool children. The theoretical part describes the characteristics of preschool age. Acquaints with the development of motor skills and their training in the natural environment. It also deals with the cognitive component of the preschool child's personality and the possibilities of its development in the countryside. Zooms problems of education in a forest environment, types of learnin and methods of training in the various components of the child's personality just in a forest. The practical part is a qualitative research method used is a questionnaire survey among kindergarten teachers to determine the most commonly used educational environment, the method standardized test for 4-6-year old children to determine the level of motor skills of the children, and the method of diagnostic interview, which examined the effect of natural environments on children's knowledge. Results in agreement with reported literature confirm the positive influence of education in the natural environment for the development of several components of the child's personality.

Les préférences, les aptitudes et la personnalité prédisent un large éventail de réalisations économiques. Je les mets en correspondance dans un cadre structurel de prise de décision en utilisant des données expérimentales uniques collectées sur plus de 1 200 personnes prenant chacune plus de 100 décisions à enjeu financier.J’estime conjointement les distributions des préférences pour le risque et le temps dans la population, leur stabilité au niveau individuel et la tendance des gens à faire des erreurs. J’utilise le modèle à préférences aléatoires (RPM) dont il a été récemment démontré que ses propriétés théoriques sont supérieures à celles des modèles précédemment employés. Je montre que le RPM a une forte validité interne. Les cinq paramètres structurels estimés dominent un large éventail de variables démographiques et socio-économiques lorsqu'il s'agit d'expliquer des choix individuels observés.Je démontre l’importance économique et économétrique de l’utilisation des chocs aux préférences et de l’incorporation du paramètre dit de « la main tremblante ». Les erreurs et l’instabilité des préférences sont liées à des capacités différentes. Je propose un indice de rationalité qui les condense en un indicateur unique prédictif des pertes de bien-être.J'utilise un modèle à facteurs pour extraire la capacité cognitive et les « Big Five » traits de la personnalité à partir de nombreuses mesures. Ils expliquent jusqu’à 50% de la variation des préférences des gens et de leur capacité à faire des choix rationnels. La conscienciosité explique à elle seule 45% et 10% de la variation transversale du taux d'actualisation et de l'aversion au risque, ainsi que 20% de la variation de leur stabilité individuelle. En outre, l'aversion au risque est liée à l'extraversion et les erreurs dépendent des capacités cognitives, de l’effort, et des paramètres des tâches. Les préférences sont stables pour l'individu médian. Néanmoins, une partie de la population a une certaine instabilité des préférences qui est indicative d’une connaissance de soi imparfaite.Ces résultats ont des implications à la fois pour la spécification des modèles économiques de forme réduite et structurels, et aussi pour l’explication des inégalités et de la transmission intergénérationnelle du statut socio-économique. / Preferences, ability, and personality predict a wide range of economic outcomes. I establish a mapping between them in a structural framework of decision-making under risk and delay using unique experimental data with information on over 100 incentivized choice tasks for each of more than 1,200 individuals.I jointly estimate population distributions of risk and time preferences complete with their individual-level stability and of people’s propensity to make mistakes. I am the first to do so using the Random Preference Model (RPM) which has been recently shown to have desirable theoretical properties over previously used frameworks. I show that the RPM has high internal validity. The five estimated structural parameters largely dominate a wide range of demographic and socio-economic variables when it comes to explaining observed individual choices between risky lotteries and time-separated payments.I demonstrate the economic and econometric significance of appending shocks directly to preferences and of incorporating the trembling hand parameter - their necessary complement in this framework. Mistakes and preference instability are not only separately identified but they are also linked to different cognitive and non-cognitive skills. I propose a Rationality Index which condenses them into a single indicator predictive of welfare loss.I use a factor model to extract cognitive ability and Big Five personality traits from noisy measures. They explain up to 50% of the variation in both average preferences and in individuals’ capacity to make consistent rational choices. Conscientiousness explains 45% and 10% respectively of the cross-sectional variation discount rates and risk aversion respectively as well as 20% of the variation in their individual-level stability. Furthermore, risk aversion is related to extraversion and mistakes are a function of cognitive ability, task design, and of effort. Preferences are stable for the median individual. Nevertheless, a part of the population exhibits some degree of preference instability consistent with imperfect self-knowledge.These results have implications both for specifying reduced form and structural economic models, and for explaining inequality and the inter-generational transmission of socioeconomic status.
