Analizar el rendimiento de unos alumnos de octavo de EGB en función de una serie de variables aptitudinales, del nivel de popularidad entre los compañeros, del grado de inadaptación y del criterio que el profesorado tiene de cada alumno. Constatar los condicionamientos que han podido influir en la elección del camino a seguir al acabar la EGB y comprobar si las variables que explican el rendimiento en octavo de EGB se mantienen en el tiempo. Muestra representativa, compuesta por 385 alumnos de 8 de EGB, de clase media-baja pertenecientes a centros estatales de la provincia de Girona. Grupos homogéneos en cuanto a edad y sexo. Realiza una breve introducción a la orientación y predicción escolar e intenta demostrar su eficacia. Plantea un modelo ecléctico con las siguientes variables independientes operacionalizadas mediante la aplicación de una batería de tests: inteligencia general, aptitudes mentales primarias, capacidad de concentración y resistencia a la fatiga, memoria, personalidad, popularidad entre compañeros y opinión de los profesores. Variable criterio: rendimiento en 8 de EGB y rendimiento en BUP y FP. Analiza cada una de las variables con la criterio o entre sí. Plantea una ecuación de predicción para el rendimiento escolar. Realiza un seguimiento de los dos cursos siguientes y valida las ecuaciones de predicción para BUP y FP. Utiliza los siguientes tests: D-48, reducción del Terman colectivo, PMA, Tolouse-Pieron, Test de memoria de TEA, adaptación para adolescentes de Bell, Test sociométrico y un cuestionaruio de opinión para los profesores. Prueba de Kolmogorov, porcentajes, Chi cuadrado, T de Student, correlaciones y ecuaciones de regresión. El rendimiento escolar se ha de fomentar entre unos márgenes de probabilidad, nunca tomarlo como una predeterminación del alumno. Se ha de procurar corregir a tiempo aquellos factores que inciden negativamente y actuar en las situaciones ambientales que favorecen el éxito. Propone que en futuros diseños sería interesante la introducción de otras variables que puedan explicar las situaciones escolares, como por ejemplo el ámbito sociocultural.

L'objectiu general d'aquesta tesi fou estudiar longitudinalment l'adquisició lectora (català i castellà), de 2n. a 5è. cursos d'Educació Primària, en una mostra de 214 alumnes (101 nenes i 113 nens) d'una escola pública catalana, a partir dels resultats obtinguts en les Proves Psicopedagògiques d'Aprenentatges Instrumentals (P.P.A.I.; Canals, Carbonell, Estaún i Añaños, 1988), aplicades a principi i final de cada curs. Les P.P.A.I. valoren la velocitat i exactitud de descodificació lectora a través de la lectura de textos diferents per a cada curs, i la comprensió lectora mitjançant exercicis diferents per a cada curs (ordenar frases, executar ordres escrites, respondre qüestions sobre el contingut d'un text...). Els resultats van ser: -La majoria de la mostra, escolaritzada en català, amb independència de la llengua més parlada a casa (català o castellà), van desenvolupar progressivament i de forma similar les habilitats lectores (català i castellà) iniciades en cursos anteriors, aconseguint a finals de 5è. l'automatització dels procés de descodificació lectora en ambdues llengües. -La velocitat lectora pràcticament es va triplicar, passant d'unes 40 paraules/minut inicials a unes 130 paraules /minut a finals de 5è. - L'exactitud lectora també va augmentar i, a finals de 5è., la majoria de la mostra llegien sense quasi errors d'exactitud. -La comprensió lectora cada cop fou més elaborada i la majoria es van afrontar progressivament, amb èxit, a activitats més complexes de comprensió lectora. -En general, el desenvolupament de les habilitats lectores va ser bastant similar en els dos sexes, però a finals de 5è. es van detectar més nens que nenes amb nivell baix (descodificació i/o comprensió) i més nenes que nens amb nivell alt (descodificació i/o comprensió). -Els subjectes que es van situar en un nivell mig (descodificació i/o comprensió) a 2n., van ser els que més es van mantenir en el mateix nivell fins a 5è. En canvi, els que a 2n. mostraven nivells extrems (alt o baix), van evolucionar de forma més variable. -Es va observar que les habilitats adequades de descodificació lectora no van implicar, necessàriament, haver desenvolupat un bon nivell de comprensió lectora. I al revés, un bon nivell de comprensió no sempre va correlacionar amb un nivell correcte de descodificació. -Després de classificar la mostra en tres subgrups (mig, alt i baix) a partir dels resultats en descodificació i comprensió en català de l'última valoració de 5è., es van observar evolucions bastant paral·leles entre els subgrups en velocitat i comprensió, mantenint-se cada subgrup en el nivell que els definia al llarg dels diferents cursos. Però un 6,54% de la mostra, amb dificultats de comprensió lectora en català a finals de 5è, va experimentar, respecte la mostra i el seu propi rendiment en la primera valoració de 5è., una important disminució de la comprensió lectora a finals de 5è.

There have only been a small number of applications of consumer decision set theory to holiday destination choice, and these studies have tended to rely on a single cross sectional snapshot of research participants’ stated preferences. Very little has been reported on the relationship between stated destination preferences and actual travel, or changes in decision set composition over time. The paper presents a rare longitudinal examination of destination decision sets, in the context of short break holidays by car in Queensland, Australia. Two questionnaires were administered, three months apart. The first identified destination preferences while the second examined actual travel and revisited destination preferences. In relation to the conference theme, there was very little change in consumer preferences towards the competitive set of destinations over the three month period. A key implication for the destination of interest, which, in an attempt to change market perceptions, launched a new brand campaign during the period of the project, is that a long term investment in a consistent brand message will be required to change market perceptions. The results go some way to support the proposition that the positioning of a destination into a consumer’s decision set represents a source of competitive advantage.

The Australian tourism tertiary education sector operates in a competitive and dynamic environment, which necessitates a market orientation to be successful. Academic staff and management in the sector must regularly assess the perceptions of prospective and current students, and monitor the satisfaction levels of current students. This study is concerned with the setting and monitoring of satisfaction levels of current students, reporting the results of three longitudinal investigations of student satisfaction in a postgraduate unit. The study also addresses a limitation of a university’s generic teaching evaluation instrument. Importance-performance analysis (IPA) has been recommended as a simple but effective tool for overcoming the deficiencies of many student evaluation studies, which have generally measured only attribute importance or importance at the end of a semester. IPA was used to compare student expectations of the unit at the beginning of semester with their perceptions of performance ten weeks later. The first stage documented key benchmarks for which amendments to the unit based on student feedback could be evaluated during subsequent teaching periods.

Enhancing children's self-concepts is widely accepted as a critical educational outcome of schooling and is postulated as a mediating variable that facilitates the attainment of other desired outcomes such as improved academic achievement. Despite considerable advances in self-concept research, there has been limited progress in devising teacher-administered enhancement interventions. This is unfortunate as teachers are crucial change agents during important developmental periods when self-concept is formed. The primary aim of the present investigation is to build on the promising features of previous self-concept enhancement studies by: (a) combining two exciting research directions developed by Burnett and Craven to develop a potentially powerful cognitive-based intervention; (b) incorporating recent developments in theory and measurement to ensure that the multidimensionality of self-concept is accounted for in the research design; (c) fully investigating the effects of a potentially strong cognitive intervention on reading, mathematics, school and learning self-concepts by using a large sample size and a sophisticated research design; (d) evaluating the effects of the intervention on affective and cognitive subcomponents of reading, mathematics, school and learning self-concepts over time to test for differential effects of the intervention; (e) modifying and extending current procedures to maximise the successful implementation of a teacher-mediated intervention in a naturalistic setting by incorporating sophisticated teacher training as suggested by Hattie (1992) and including an assessment of the efficacy of implementation; and (f) examining the durability of effects associated with the intervention.

Background Motivation has been identified as an area of difficulty for children with Down syndrome. Although individual differences in mastery motivation are presumed to have implications for subsequent competence, few longitudinal studies have addressed the stability of motivation and the predictive validity of early measures for later academic achievement, especially in atypical populations. Method The participants were 25 children with Down syndrome. Mastery motivation, operationalised as persistence, was measured in early childhood and adolescence using tasks and parent report. At the older age, preference for challenge, another aspect of mastery motivation, was also measured and the children completed assessments of academic competence. Results There were significant concurrent correlations among measures of persistence at both ages, and early task persistence was associated with later persistence. Persistence in early childhood was related to academic competence in adolescence, even when the effects of cognitive ability at the younger age were controlled. Conclusions For children with Down syndrome, persistence appears to be an individual characteristic that is relatively stable from early childhood to early adolescence. The finding that early mastery motivation is significant for later achievement has important implications for the focus of early interventions.

Objective: The study investigated previous research findings and clinical impressions which indicated that the intensity of grief for parents who had lost a child was likely to be higher than that for widows/widowers, who in turn were likely to have more intense reactions than adult children losing a parent. Method: In order to compare the intensities of the bereavement reactions among representative community samples of bereaved spouses (n = 44), adult children (n = 40) and parents (n = 36), and to follow the course of such phenomena, a detailed Bereavement Questionnaire was administered at four time points over a 13-month period following the loss. Results: Measures based on items central to the construct of bereavement showed significant time and group differences in accordance with the proposed hypothesis. More global items associated with the construct of resolution showed a significant time effect, but without significant group differences. Conclusions: Evidence from this study supports the hypothesis that in non-clinical, community-based populations the frequency with which core bereavement phenomena are experienced is in the order: bereaved parents bereaved spouses bereaved adult children.
