‘A planet of confusion and debate’: children's and young people's response to the news coverage of Pluto's loss of planetary status

Despite calls that the school science curriculum should develop among students an ability to understand and respond critically to science-related media reports, very little research has been directed toward an important matter relevant to that aim, namely, how children and young people, untutored, react to science in the news. This study sought, in the context of media coverage of the debate surrounding the planetary status of Pluto, to explore this issue. A questionnaire, completed by 350 students aged between eight and 18, showed just over half of the children and young people were able to write relevantly about the subject though it was the gist not the detail of the story they recounted. There was evidence, nonetheless, that this media-acquired information functioned as active rather than passive knowledge. Students demonstrated relatively few misconceptions and those presented were predominately pre-existing rather than media-derived. As with the wider public, many of the children and young people held strong opinions on Pluto's loss of planethood. Such responses diminished with age, however, with older students expressing a degree of indifference. The paper concludes with a discussion of some implications of the research findings for science instruction.

Distúrbios osteomioarticulares : lombalgia e escoliose : prevalência e fatores associados : um estudo analítico e transversal em adolescentes da região do Algarve

RESUMO - Introdução: Os distúrbios osteomioarticulares envolvem diversas condições donde se destacam a lombalgia e a escoliose, a primeira considerando o fato que a sua prevalência tem vindo a aumentar em adolescentes consistindo num problema crescente de saúde pública que envolve custos indiretos e a escoliose pela ausência de estudos nacionais. Diversos fatores físicos, genéticos, mecânicos, comportamentais e ambientais podem estar envolvidos na patogénese das lombalgias e escolioses. O ambiente escolar, incluindo as posturas adotadas pelos alunos e o transporte das mochilas escolares, e alguns hábitos de estilos de vida constituem fatores que podem contribuir para o desenvolvimento destes distúrbios osteomioarticulares. Este estudo também aborda o estado ponderal, nomeadamente o excesso de peso e a obesidade, pois este é referido frequentemente como um potencial fator de risco destes distúrbios osteomioarticulares (apesar de ainda apresentar controvérsia na literatura), além de ser, por si só, atualmente considerado como um dos mais graves problemas de saúde pública a nível mundial. Objetivos do estudo: (1) determinar a prevalência pontual, anual e ao longo da vida de lombalgia, assim como a prevalência de escoliose em adolescentes da região do Algarve; (2) identificar os fatores associados ao desenvolvimento destes distúrbios osteomioarticulares; (3) determinar a prevalência de excesso de peso e de obesidade e explorar a sua eventual associação com a prevalência de lombalgia e escoliose em adolescentes; (4) comparar os resultados obtidos nos diferentes métodos antropométricos (Índice de massa corporal - IMC, medição das pregas cutâneas e circunferência abdominal) e verificar a sua concordância. Material e métodos: O desenho deste estudo foi de natureza observacional, analítico e transversal. O estudo foi aprovado pela Comissão de Ética da Administração Regional de Saúde do Algarve, pela Direção Regional de Educação do Algarve, pela Direção-Geral de Inovação e de Desenvolvimento Curricular, Ministério da Educação e Ciência, e pelas Direções dos Agrupamentos de Escolas que participaram do projeto. A amostra incluiu 966 adolescentes da região do Algarve, sul de Portugal, com idades compreendidas entre os 10 e 16 anos (12,24±1,53 anos), sendo 437 (45,2%) do sexo masculino e 529 (54,8%) do feminino. O método de amostragem foi aleatório estratificado, com base nos concelhos da região do Algarve, assumindo que poderia existir heterogeneidades geográficas. Os instrumentos de medida foram aplicados num único momento (2011/2012) e incluíram o Questionário de Lombalgia e Hábitos Posturais para caracterizar a presença de lombalgia e os hábitos posturais adotados pelos alunos em casa e na escola, o escoliómetro para avaliar a presença de escoliose, a balança, o estadiómetro (sendo posteriormente calculado o IMC), o adipómetro e a fita métrica. A análise dos dados incluiu técnicas de estatística descritiva, gráficas e analíticas aplicadas à todas as variáveis em estudo. Para determinar a associação entre as variáveis do estudo foi utilizada a estatística inferencial, nomeadamente o teste de independência do Qui-quadrado. Para analisar as correlações entre as medidas obtidas com os métodos antropométricos (na sua forma quantitativa), foi utilizado o coeficiente de Spearman. A influência das diversas variáveis na presença de lombalgia foi aferida através de regressões logísticas binárias, sendo os resultados apresentados como odds ratios brutos e ajustados e respetivos intervalos de confiança. Resultados: O presente estudo revelou uma elevada prevalência de lombalgia (anual: 47,2%; pontual: 15,7%; ao longo da vida: 62,1%). As raparigas apresentaram 2,05 de probabilidade de apresentar lombalgia comparativamente aos rapazes (IC 95%: 1,58-2,65; p<0,001), assim como os alunos com idades mais avançadas (13-16 anos) comparativamente aos mais novos (10-12 anos) que tiveram 1,54 de chances (IC 95%: 1,19-1,99; p=0,001). Os alunos que indicaram adotar uma postura de sentado com a coluna vertebral posicionada incorretamente apresentaram 2,49 de probabilidade de revelar lombalgia (IC 95%: 1,91-3,24; p<0,001), os alunos que afirmaram se posicionar de forma inadequada para assistir televisão ou jogar videojogos tiveram a probabilidade de 2,01 (IC 95%: 1,55- 2,61; p<0,001) e aqueles que adotaram a postura de pé incorretamente tiveram 3,39 de chance de apresentar lombalgia (IC 95%: 2,19-5,23; p<0,001). A escoliose esteve presente em 41 (4,2%) alunos. As raparigas apresentaram a maior prevalência (4,5% versus 3,9%) do que os rapazes e o mesmo foi observado nas raparigas que apresentaram a menarca tardia (8,6% versus 3,3%) e os que foram classificados como magros (7,1%), não sendo no entanto estas diferenças estatisticamente significativas. Relativamente à prevalência de excesso de peso e obesidade, os valores variaram de 31,6%, 61,4% e 41,1% de acordo com a medição do IMC, pregas cutâneas e circunferência abdominal, respetivamente. Os valores obtidos com a avaliação dos três métodos antropométricos apresentaram um elevado alto grau de correlação entre o IMC e as pregas cutâneas (p<0,001; r=0,712), entre o IMC e circunferência abdominal (p<0,001; r=0,884) e entre a circunferência abdominal e as pregas cutâneas (p<0,001; r=0,701). Conclusões: O presente estudo revelou valores de prevalência de lombalgia semelhante a estudos anteriores sendo que os alunos com idade mais avançada, ou do sexo feminino ou aqueles que adotavam a postura sentada e de pé de forma inadequada ou os que transportavam indevidamente a mochila escolar apresentaram a maior prevalência. Quanto à presença de escoliose, observou-se uma baixa prevalência não sendo verificada nenhuma associação significativa com os fatores analisados. Relativamente ao estado ponderal, verificou-se uma elevada prevalência de excesso de peso e obesidade, com a utilização dos três métodos antropométricos: IMC, medição das pregas cutâneas e circunferência abdominal, tendo sido verificado um elevado grau de correlação entre estes três métodos antropométricos. Este estudo contribuiu para determinar a magnitude destes distúrbios osteomiarticulares nesta população específica, assim como seus possíveis fatores associados. De acordo os resultados obtidos no presente estudo, torna-se necessário ações de intervenção nas escolas, envolvendo não somente os alunos, mas toda a comunidade escolar, com o objetivo de prevenção destes distúrbios osteomioarticulares através da promoção de hábitos de vida saudável.

Teaching Principled negotiation skills to parents and their children : the impact of parental involvement /

This study explored the impact of training parents and children concurrently in principled negotiation skills for the purpose of developing negotiation skills and problem solving abilities in children. A second experimental group was utilized to determine the viability of negotiation skills training of junior elementary students for the purpose of improving problem solving and conflict resolving abilities. The student population in each experimental group was trained using The Program for Young Negotiators (Curhan, 1996). A control group was also established using the remaining grade four and five students attending the participating school. These students did not receive training as part of this study. Student group distribution was as follows: Experimental group 1 (students with parent participant) consisted of 10 (5 grade five and 5 grade 4 students), Experimental group 2 students without parent participant) consisted of 48 (20 grade 4 and 28 grade 5 students), and the Control group 3 (55 grade 4 and 5 students). The impact of training was measured using the Five Factor Negotiation Scale developed for use with the Program for Young Negotiators (Curhan, 1996). This measure was employed as a pre- and post-test questionnaire to the total student population, (113 students) to determine levels of ability in each of the key elements of negotiation, personal initiative, collaboration, communication, conflict based perspective taking, and conflict resolution approach (Nakkula & Nikitopoulos, unpublished). This measure has a coefficient alpha of .75 which is acceptable for this type of affective instrument. As well, open ended ability questions designed to measure ability, knowledge, and behaviour as they relate to negotiation skill application were given to the total student population, (113 students). Finally, journals were maintained by the students in both experimental groups, and informal feedback discussions were held with students and parents participating in the study.The intent of using both qualitative and quantitative measures was to provide an overall perspective of student abilities as they related to principled negotiation skills. While the quantitative measures were from the student perspective, more qualitative information was sought from parents and teachers through informal interviews, discussions, and use of confidential feedback cards. For analysis purposes, the ability questions were randomly selected for Experimental group 2 and Control group 3 in an effort to balance the groups more equitably with Experimental group 1. The findings of this study indicate that students of the junior elementary school age can be taught how to perceive conflict in a more constructive way. However, they are not as likely to use their skills when the conflict is with a sibling as they are with a peer, a teacher, or a parent. While no statistically significant differences between mean scores for Experimental groups 1 and 2 exist some subtle differences are noted. Overall, increases in mean scores for grade 4 students exceeded the increases for grade 5 students within Experimental group 1 . The implication being that younger students benefit more from having a parent trained in principled negoUation skills than older students. The skill level of a parent in principled negotiation can not be underesUmated. Without a consistent and effective role model the likelihood of developing student skill level to a point of automaticity is greatly reduced. Enough so that perhaps the emphasis should be placed on training parents more so than the students.

Bullying as a social process : factors influencing bystander behaviour

Bullying was approached as a social phenomenon in the present study. The central aim of this thesis was to uncover some of the factors that contribute to the attitudes and behavioural choices of bystanders during bullying situations. With this type of information, interventions can be tailored to change the behaviour of bystanders during bullying situations, and thus the ethos of the larger group. Thus, acting to alter the available sources of reinforcement for bullying behaviour and peer intervention attempts. Six hundred and twenty-six students participated. Students were sampled from grades 4 (n=140), 5 (n=l 13), 7 (n=205), and 8 (n=168). Students were measured for their involvement in bullying and victimization, as well as for involvement in the following bystander behaviours: encouraging, onlooking, defending, and seeking adult support. In addition, students were measured for tolerance of deviance, pro-victim attitudes, social anxiety and fear, and self-efficacy for peer intervention. Last, students were asked to complete a series of qualitative measures, including a series of hypothetical vignettes and open-ended questions. Analyses centered on the following areas: 1) rates of bullying, victimization, and bystander behaviour; 2) the influence of age and gender on bystander behaviour; 3) the characteristics associated with students who predominantly report involvement with defending, seeking adult assistance, encouraging, and onlooking behaviour; and 4) the influence of past involvement with bullying and victimization on bystander behaviour. b .--' -i . k Rates of bullying, victimization, and bystander behaviour were comparable to findings in the existing literature, where male students were more likely than female students to report involvement in both bullying and victimization. Boys were more likely than girls to report participation in encouraging and onlooking behaviours, while being less likely to report involvement in defending and seeking adult assistance. Partly consistent with existing findings, older students were more likely to report involvement in bullying, encouraging, and onlooking behaviour than younger students, who were more likely to report victimization, defending, and seeking adult assistance. Self-identified encouragers and onlookers reported a similar array of characteristics, in that they tended express high levels of tolerance of deviance, while expressing low levels of pro-victim attitudes and self-efficacy for peer intervention. Likewise, self-identified defenders and seekers of adult assistance tended to report a similar array of characteristics to each other, in that they tended to report low levels of tolerance of deviance, while expressing high levels of pro-victim attitudes and self efficacy for peer intervention. Additionally, self-identified bullies and self-identified bully-victims tended to report increased involvement in encouraging and onlooking, whereas self-identified victims tended to report increased involvement in defending behaviour and seeking adult assistance. Results are discussed in terms of implications for bullying prevention and intervention. Specifically, evidence from the present study suggests that as bystanders, students predominantly act to either support bullying acts or to support the victims of these acts, or alternatively, to actively remain outside bullying situations. Thus, encouraging students to make small changes in the way they express these sentiments during bullying situations would act to alter the culture of the larger peer group and the sources of reinforcement available for bullying acts as well as peer intervention attempts.

Essays on education and family planning

Le capital humain d’un pays est un facteur important de sa croissance et de son développement à long terme. Selon l’Unicef, ce capital humain est constitué en donnant à chaque enfant un bon départ dans la vie : non seule- ment la possibilité de survivre, mais aussi les conditions nécessaires pour se développer et réaliser tout son potentiel. Malheureusement, cet état de fait est loin d’être une réalité en Afrique Subsaharienne. En effet, selon toujours l’Unicef et sur la base d’enquêtes ménages dans 21 pays d’Afrique de l’Ouest et du Centre, c’est près de 32 millions d’enfants qui ont l’âge officiel d’être scolarisés, mais qui ne le sont pas. A ces chiffres, il faut ajouter 17 millions d’enfants scolarisés qui risquent fortement l’exclusion. De son Côté, l’OMS pointe du doigt la mauvaise santé des enfants dans cette région. Ainsi, les décès d’enfants sont de plus en plus concentrés en Afrique subsaharienne où les enfants ont plus de 15 fois plus de risques de mourir avant l’âge de cinq ans que les enfants des régions développées. Les difficultés économiques apparaissent comme la première explication des obstacles à l’amélioration du bien être des enfants aussi bien du côté de l’offre que de la demande. Cette thèse relie trois essais sur d’une part le lien entre conflit armés, l’éducation et la mortalité des enfants et d’autre part sur le lien entre fertilité et éducation des enfants en milieu urbain. Le premier chapitre identifie l’impact de la crise politico-militaire de la Côte d’Ivoire sur le bien être des enfants, en particulier sur l’éducation et la mor- talité infanto-juvénile en exploitant la variation temporelle et géographique de la crise. Il ressort de cette analyse que les individus qui vivaient dans les régions de conflit et qui ont atteint durant la crise, l’âge officiel d’entrer à l’école ont 10% moins de chance d’être inscrits à l’école. Les élèves qui habitaient dans des régions de conflit pendant la crise ont subit une diminu- tion du nombre d’années scolaire d’au moins une année. Les élèves les plus v vi âgés et qui sont susceptibles d’être au secondaire ont connu une décroissance du nombre d’année scolaire d’au moins deux années. Il ressort également que la crise ivoirienne a accru la mortalité infanto-juvénile d’au moins 3%. Mes résultats suggèrent également que la détérioration des conditions de vie et la limitation de l’utilisation des services de santé au cours du conflit con- tribuent à expliquer ces effets négatifs. Des tests de robustesse incluant un test de placebo suggèrent que les résultats ne sont pas dus à des différences préexistantes entre les régions affectées par le conflit et celles non affectées. Le deuxième chapitre étudie les disparités intra-urbaines en matière d’arbitrage entre le nombre d’enfant et la scolarisation des enfants en se focalisant sur le cas de Ouagadougou (Capitale du Burkina Faso). Dans cette ville, au moins 33% des deux millions d’habitants vivent dans des zones informelles (appelées localement des zones non-loties). Cette sous-population manque d’infrastructures socioéconomiques de base et a un niveau d’éducation très bas. Dans ce chapitre, prenant en compte la possible endogénéité du nombre d’enfants et en utilisant une approche "two-step control function" avec des modèles Probit, nous investiguons les différences de comportement des mé- nages en matière de scolarisation entre zones formelles et zones informelles. Nous nous focalisons en particulier sur l’arbitrage entre la "quantité" et la "qualité" des enfants. Compte tenu de l’hétérogénéité des deux types de zones, nous utilisons les probabilités prédites pour les comparer. Nos princi- pales conclusions sont les suivantes. Tout d’abord, nous trouvons un impact négatif de la taille de la famille sur le niveau de scolarisation dans les deux types de zone. Cependant, nous constatons que l’impact est plus aigu dans les zones informelles. Deuxièmement, si nous supposons que le caractère en- dogène du nombre d’enfants est essentiellement due à la causalité inverse, les résultats suggèrent que dans les zones formelles les parents tiennent compte de la scolarisation des enfants dans la décision de leur nombre d’enfants, mais ce ne est pas le cas dans les zones informelles. Enfin, nous constatons que, pour des familles avec les mêmes caractéristiques observables, la probabilité d’atteindre le niveau post-primaire est plus élevée dans les zones formelles que dans les zones informelles. En terme d’implications politique, selon ces résultats, les efforts pour améliorer la scolarisation des enfants ne doivent pas être dirigées uniquement vers les zones rurales. En plus de réduire les frais de scolarité dans certaines zones urbaines, en particulier les zones informelles, un accent particulier devrait être mis sur la sensibilisation sur les avantages de l’éducation pour le bien-être des enfants et leur famille. Enfin, du point vii de vue méthodologique, nos résultats montrent l’importance de tenir compte de l’hétérogénéité non observée entre les sous-populations dans l’explication des phénomènes socio-économiques. Compte tenu du lien négatif entre la taille de la famille et la scolarisation des enfants d’une part et les différences intra-urbaines de comportement des ménages en matière de scolarisation, le trosième chapitre étudie le rôle des types de méthodes contraceptives dans l’espacement des naissances en mi- lieu urbain. Ainsi, en distinguant les méthodes modernes et traditionnelles et en utilisant l’histoire génétique des femmes, ce chapitre fait ressortir des différences de comportement en matière de contraception entre les femmes des zones formelles et informelles à Ouagadougou (capitale du Burkina Faso). Les résultats montrent que les deux types de méthodes contraceptives aug- mentent l’écart des naissances et diminuent la probabilité qu’une naissance se produise moins de 24 mois après la précédente. Prendre en compte les caractéristiques non observées mais invariants avec le temps ne modifie pas significativement l’amplitude du coefficient de l’utilisation de la contracep- tion moderne dans les deux types de zone. Toutefois, dans la zone informelle, la prise en compte les effets fixes des femmes augmentent significativement l’effet des méthodes traditionnelles. Les normes sociales, la perception de la planification familiale et le rôle du partenaire de la femme pourraient expli- quer ces différences de comportement entre les zones formelles et informelles. Par conséquent, pour améliorer l’utilisation de la contraception et de leur efficacité, il est essentiel de hiérarchiser les actions en fonction du type de sous-population, même dans les zones urbaines.

Como resolver uma situação de não aprendizagem: um estudo psicogenético sobre a construção do conhecimento social

Based on the Piagetian theory and on the research about the construction of Social Knowledge, this article presents the beliefs of children and adolescents regarding the resolution of a situation of not learning. Data were obtained from 80 students, between 06 and 16 years, who analyzed a story involving this issue. The main results indicate that most participants are not able think about the situation contained in the story in a more complex way, disregarding processes and elements, thus. They tend to give simplistic answers and it demonstrates the characteristics of the most elementary level of understanding of social reality. Even among the older students, a less elaborated representation of this daily social question, “to learn or not to learn”, was also preponderate.

Competência de juízo moral dos estudantes de medicina: um estudo piloto

The authors conducted a cross-sectional short-term study using Lind's Moral Judgment Test (MJT) to compare the moral judgment competence (C-score) among students in the first and eighth semesters from a medical school in the Northeast region of Brazil. This study also evaluated the influence of such factors as age and gender on moral competence. A difference equal to or greater than 5.0 points (absolute effect-size) on the C-score was considered significant. A regression of moral judgment competence among the students in their eighth semester in relation to the students in the first semester (C-score: 20.5 and 26.2 points, respectively) was observed. In the analysis of the students' performances in terms of MJT dilemmas, the phenomenon of moral segmentation was observed in both semesters, and the students performed better on the worker's dilemma than on the doctor's dilemma. Among students in the same semester of study, older students had lower C-scores. When comparing performance by gender, there was no significant difference between men's and women's C-scores. The finding of regression or stagnation in moral competence among the medical students demands deep reflection by those who work with the political-pedagogical projects of medical schools and by the entire faculty, in order to seek strategies to reverse this condition.

Coherence and Historical understanding in children's Biography and Historical Nonfiction Literature: A Content Analysis of Selected Orbis Pictus Books

The purpose of this study was to investigate a selection of children's historical nonfiction literature for evidence of coherence. Although research has been conducted on coherence of textbook material and its influences on comprehension there has been limited study on coherence in children's nonfiction literature. Generally, textual coherence has been seen as critical in the comprehensibility of content area textbooks because it concerns the unity of connections among ideas and information. Disciplinary coherence concerns the extent to which authors of historical text show readers how historians think and write. Since young readers are apprentices in learning historical content and conventions of historical thinking, evidence of disciplinary coherence is significant in nonfiction literature for young readers. The sample of the study contained 32 books published between 1989 and 2000 ranging in length from less than 90 pages to more than 150 pages. Content analysis was the quantitative research technique used to measure 84 variables of textual and disciplinary coherence in three passages of each book, as proportions of the total number of words for each book. Reliability analyses and an examination of 750 correlations showed the extent to which variables were related in the books. Three important findings emerged from the study that should be considered in the selection and use of children's historical nonfiction literature in classrooms. First, characteristics of coherence are significantly related together in high quality nonfiction literature. Second, shorter books have a higher proportion of textual coherence than longer books as measured in three passages. Third, presence of the author is related to characteristics of coherence throughout the books. The findings show that nonfiction literature offers students content that researchers have found textbooks lack. Both younger and older students have the opportunity to learn the conventions of historical thinking as they learn content through nonfiction literature. Further, the children's literature, represented in the Orbis Pictus list, shows students that authors select, interpret, and question information, and give other interpretations. The implications of the study for teaching history, teacher preparation in content and literacy, school practices, children's librarians, and publishers of children's nonfiction are discussed.

Flexibilidad en la resolución de problemas de identificación de patrones lineales en estudiantes de educación secundaria

El objetivo de este trabajo es caracterizar la flexibilidad, entendida como habilidad para modificar la estrategia de resolución de un problema cuando se modifica la demanda de la tarea, de estudiantes de educación secundaria (12-16 años) en problemas de reconocimiento de patrones con varios apartados. Se utiliza una metodología de tipo cualitativo analizando las respuestas de los estudiantes en base a dos criterios: corrección de las respuestas y estrategias de resolución, y agrupando las que presentan características semejantes. Los resultados indican tres perfiles de estudiantes en relación a la flexibilidad en el uso de estrategias y el éxito alcanzado. El primero agrupa a los estudiantes que usan sólo la estrategia recursiva; la mayor parte de ellos se bloquea al aumentar la demanda cognitiva de la tarea; predominan los estudiantes de 12-13 años. El segundo perfil corresponde a los que cambian de una estrategia recursiva a una aproximación proporcional dando un resultado incorrecto; es más frecuente en los estudiantes de 13-14 años. Finalmente, el tercer perfil agrupa a los estudiantes que al aumentar la demanda cognitiva de la tarea cambian con éxito de una estrategia recursiva a una funcional; su frecuencia aumenta con la edad. Se concluye que la flexibilidad necesaria para identificar patrones cuando se incrementa la demanda de la tarea está relacionada con los conocimientos de los estudiantes y con el control y la regulación del proceso de resolución. Por otra parte, los estudiantes más jóvenes manifestaron menor grado de flexibilidad que los más mayores.

Diferencias de género y edad en autoconcepto en estudiantes adolescentes chilenos

Investigaciones previas han puesto de manifiesto la importancia del estudio del autoconcepto durante la adolescencia. El objetivo de este estudio consistió en analizar las diferencias de género y edad en las distintas dimensiones del autoconcepto en una muestra de 1414 estudiantes chilenos de entre 13 y 18 años. El autoconcepto fue evaluado mediante la versión breve del SDQII. Los resultados evidenciaron diferencias de género para las dimensiones Autoconcepto Verbal, Apariencia Física, Sinceridad/Veracidad y Autoestima en favor de las jóvenes, así como diferencias en el Autoconcepto Matemático, Habilidades Físicas, Estabilidad Emocional y Relación con los Padres en favor de los varones. También se observó una tendencia en los alumnos de mayor edad a puntuar más alto en Autoconcepto Académico General, Habilidades Físicas, Apariencia Física, Relaciones con el Sexo Opuesto y Autoestima, que sus iguales de menor edad. Este mismo patrón, pero a la inversa, se obtuvo para las dimensiones de Autoconcepto Matemático, Verbal y Estabilidad Emocional. Los resultados no replicaron la tendencia de los varones, reportada en estudios previos, a valorar más positivamente su físico y a poseer una autoestima más elevada que las mujeres, así como a percibir más negativamente sus relaciones paterno-filiales.

The Long and Winding Road: Heterogeneity in the Form and Timing of Postsecondary Education

Thesis (Ph.D.)--University of Washington, 2016-06

The relationship of aptitude, course grades, and program length, to performance on a standards based test (NCLEX -RN)

The purpose of this study was threefold: first, to investigate variables associated with learning, and performance as measured by the National Council Licensure Examination for Registered Nurses (NCLEX-RN). The second purpose was to validate the predictive value of the Assessment Technologies Institute (ATI) achievement exit exam, and lastly, to provide a model that could be used to predict performance on the NCLEX-RN, with implications for admission and curriculum development. The study was based on school learning theory, which implies that acquisition in school learning is a function of aptitude (pre-admission measures), opportunity to learn, and quality of instruction (program measures). Data utilized were from 298 graduates of an associate degree nursing program in the Southeastern United States. Of the 298 graduates, 142 were Hispanic, 87 were Black, non-Hispanic, 54 White, non-Hispanic, and 15 reported as Others. The graduates took the NCLEX-RN for the first time during the years 2003–2005. This study was a predictive, correlational design that relied upon retrospective data. Point biserial correlations, and chi-square analyses were used to investigate relationships between 19 selected predictor variables and the dichotomous criterion variable, NCLEX-RN. The correlation and chi square findings indicated that men did better on the NCLEX-RN than women; Blacks had the highest failure rates, followed by Hispanics; older students were more likely to pass the exam than younger students; and students who passed the exam started and completed the nursing program with a higher grade point average, than those who failed the exam. Using logistic regression, five statistical models that used variables associated with learning and student performance on the NCLEX-RN were tested with a model adapted from Bloom's (1976) and Carroll's (1963) school learning theories. The derived model included: NCLEX-RNsuccess = f (Nurse Entrance Test and advanced medical-surgical nursing course grade achieved). The model demonstrates that student performance on the NCLEX-RN can be predicted by one pre-admission measure, and a program measure. The Assessment Technologies Institute achievement exit exam (an outcome measure) had no predictive value for student performance on the NCLEX-RN. The model developed accurately predicted 94% of the student's successful performance on the NCLEX-RN.

No cotidiano da escola: o pensar e agir de jovens e adultos

The necessity of the view of the Youth and Adults Education (EJA) subjects beyond of their academic failures becomes imperative for a reconfiguration of this teaching modality. Thus, the compromise of this study is to go into these subjects‘ universe, give them a voice and, therefore, understand, in general, the web of relationships between these subjects and the school. It is understood that it is not possible to figure out the means attributed by the subjects without consideration, as an essential element, the social context in which such means has been built. For the development of this study, the methodology adopted was the ethnographic research. The procedures used for the data construction were the participative observation, the semi-structured interviews with a focal group, and the individualized semi-structured interviews. For the understanding of the data constructed in the field, the content analysis technique was used, which reach the expectations of an interpretative analysis. The observation occurred mainly in the classrooms, on a public school, located in a City of Natal/RN. The interviews were taken with a sample of eight students, males and females, with 25 to 60 year-olds. Such interviews highlight that for the young adult students, the school is much more than a place to learn. They realize such space as enabler of social interaction, as well as the possibility of rising through new professional horizons and, therefore achieve a social mobility. For the older students, mainly among women, the return to the school benches brings into the learning discourse, the desire of making new friends, having moments of meeting, chatting and relaxation, finally, to forget the problems of the day by day. The school quotidian observation allows a better understanding of the action of the subjects in relationship with the school practices. Finally, it can be affirmed that seeking for the school has not only the intention to recover the time lost in the childhood. Learning remains as a secondary goal. It does not matter whether they will be retained or promoted to the next level at the end of the academic year, what really matters is to be in school.

Digitala primärkällor i historieundervisningen: En utmaning för elevers historiska tänkande och historiska empati

In this study, 110 Swedish upper secondary students use a historical database designed for research. We analyze how they perceive the use of this digital tool in teaching and if they are able to use historical thinking and historical empathy in their historical writing and presentations. Using case-study methodology including questionnaires, observations, interviews and text analysis we find this to be a complex task for students. Our results highlight technological problems and problems in contextualizing historical evidence. However, students show interest in using primary sources and ability to use historical thinking and historical empathy, especially older students in more advanced courses when they have time to reflect upon the historical material.

Taiwanese nursing students' attitudes toward older people

The aim of this research was to establish Taiwanese undergraduate nursing students’ attitudes toward older people. This study involved a cross-sectional survey of 362 nursing students in a university in southern Taiwan. Overall, the results showed that nursing students had positive attitudes toward older people. Moreover, the findings suggested that nursing students’ intention to work with older people and gender were important factors influencing their attitudes toward older people. The findings of this study indicate that efforts are required to maintain these positive attitudes. In addition, provision of nursing courses related to older people that place greater emphasis on attitudes about aging and that take into account students’ working experience and career intention will lead to higher quality of care for older people.
