Revista electrónica de investigación y evaluación educativa

2010

Este trabajo tiene el propósito de mostrar el uso de la metodología de Modelos de Ecuaciones Estructurales (SEM) para validar la estructura conceptual de cuestionarios de contexto que se utilizan en los estudios nacionales e internacionales para evaluar el logro educativo de los escolares. Desgraciadamente, los organismos evaluadores no destinan los mismos recursos técnicos a los cuestionarios de contexto que a las pruebas de aprendizaje, por lo que rara vez los primeros son sujetos a estudios de validez. Para mostrar el uso de la metodología SEM, se seleccionó el cuestionario dirigido a alumnos que utilizó el Instituto Nacional para la Evaluación de la Educación (INEE) para conocer los fac…

Background questionnaires of PISA : a study of the assessment indicators

2016

El sistema de evaluación de PISA ha generado y continúa generando intensos debates sobre su estructura y utilidad. Este artículo se centra en los cuestionarios de contexto, como forma de analizar y entender de manera adecuada los resultados. Los objetivos son analizar los indicadores de contexto que se utilizan en las distintas ediciones de las pruebas PISA, su utilización en distintos estudios y en los resultados de estos estudios. Se proporciona una visión general del modelo utilizado para conseguir que estos indicadores dejen de ser algo que acompaña a las prueba de rendimiento para que alcancen su verdadero sentido: analizar conjuntamente el rendimiento junto con las variables que…

Assessment of Modelling Structure and Data Availability Influence on Urban Flood Damage Modelling Uncertainty

2014

Abstract In modelling application, different model structures may be equally reliable in terms of calibration ability but they may produce different uncertainty levels; moreover, available data during model calibration may influence the uncertainty linked to the predictions of the same modelling structure. In the present paper, Bayesian model-averaging was applied to several flood damage estimation models in order to identify the best model combination for urban flooding distribution analysis in Palermo city center (Italy). During the analysis, was taken into account the effect of the available data growth on the model uncertainty with respect to the different combination of models outputs.

Validación de una escala reducida para valorar competencias básicas de aprendizaje del alumnado universitario

2021

[ES] La relación entre evaluación y desarrollo de las competencias básicas para el aprendizaje del alumnado universitario es indiscutible, pues la evaluación juega un papel relevante al determinar lo que aprende el alumnado y la forma en la que realiza sus tareas académicas. Con el objetivo de contribuir en el avance de la metodología evaluativa para la valoración de dichas competencias, este estudio pretende validar una escala reducida la cual ha sido adaptada del Autoinforme de desarrollo de las competencias básicas de los estudiantes –COMPES-. Dicha escala busca medir, de forma concisa y breve, el nivel competencial percibido por parte del alumnado respecto a un conjunto de competencias …

The Development of the Dealing with Challenging Interaction (DCI) Method to Evaluate Teachers’ Social Interaction Skills

2012

The Dealing with Challenging Interaction (DCI) method was developed to measure social interaction skills of teacher study groups. The participants were 70 teachers from three schools. The inter-rater agreement, Cohen’s kappa, varied between 0.57- 1.00. The discriminant validity was supported by a cluster analysis differentiating between the skilful and less skilful teachers. The results of the supplementary instrument were equivalent to the cluster analysis maintaining criterion oriented validity of the method developed. The DCI appeared to be a reliable and valid tool for measuring teachers’ social interaction skills. Peer reviewed

18F-FDG PET imaging of breast cancer : evaluation of the metabolic behaviour of the different breast cancer subtypes and prediction of the tumor resp…

2015

Positron Emission Tomography (PET) with 18Fluoro-deoxyglucose (18F-FDG) is the reference imaging examination for in-vivo quantification of the glucidic metabolism of tumour cells. It allows for the monitoring of tumour metabolic changes during chemotherapy. Breast cancer comprises several distinct genomic entities with different biological characteristics and clinical behaviours, leading to different tailored treatments. The aim of this doctoral thesis was to evaluate the relationship between the different biological entities of breast cancer and the tumour metabolic behaviour during neoadjuvant chemotherapy. We have also retrieved, among the various metabolic parameters on PET images, the …

La Valle dei Templi in epoca medioevale. Caratterizzazione antropologica e paleopatologica delle sepolture antistanti in Tempio della Concordia

2021

Riassunto ― Il lavoro presenta i risultati delle analisi bio-archeologiche effettuate su resti scheletrici umani rinvenuti in quattordici sepolture di epoca medioevale rinvenute nel Parco Archeologico della Valle dei Templi di Agrigento (Sicilia). L’obiettivo è stato l’acquisizione delle informazioni necessarie per la ricostruzione del profilo biologico di ciascun individuo, al fine di determinarne il sesso, la stima dell’età biologica alla morte, la stima della statura e la valutazione delle patologie e degli indicatori di stress occupazionale mediante le correnti metodologie e tecniche diagnostiche di tipo antropologico. Sebbene il cattivo stato di conservazione di alcuni individui non ne…

Summary ― The work presents the results of the bio-archaeological analyzes carried out on human skeletal remains found in fourteen burials of Medieval chronology at the Archaeological Park of Valle dei Templi in Agrigentum (Sicily). The aim of the work was the acquisition of the information necessary for the reconstruction of the biological profile of each individual throught the determination of sex the estimate of the biological age at death the estimate of height and the evaluation of pathologies and markers of occupational stress through current anthropological diagnostic methodologies and techniques. Althought the poor state of conservation of some individuals has not allowed their whole anthropological characterization the investigations have highlighted the heterogeneity relating to the age groups and have allowed us to ascertain the presence of pathological alterations in subjects of mature age sometimes of unknown etiology such as DISH (Diffuse Idiopathic Hyperostosis). The sample size is not representative of the entire population but subsequent insights will provide a better understanding of the population dynamics of Medieval Agrigentum.Settore BIO/08 - Antropologia
