What to Expect and What to Focus on in SQL Query Teaching
2019
In the process of learning a new computer language, writing erroneous statements is part of the learning experience. However, some errors persist throughout the query writing process and are never corrected. Structured Query Language (SQL) consists of a number of different concepts such as expressions, joins, grouping and ordering, all of which by nature invite different possible errors in the query writing process. Furthermore, some of these errors are relatively easy for a student to fix when compared to others. Using a data set from three student cohorts with the total of 744 students, we set out to explore which types of errors are persistent, i.e., more likely to be left uncorrected by…
A Performance-Based Test for Assessing Students’ Online Inquiry Competences in Schools
2018
In this paper, we introduce a performance-based test for measuring adolescents’ competences in online inquiry. The test covers four competence dimensions: (1) searching and selecting relevant sources, (2) identifying the main ideas presented in the sources, (3) evaluating the credibility of the sources, and (4) synthesizing information across the sources. We implement a technological solution called NEURONE to carry out this routine. The scoring of the test data is demonstrated by presenting preliminary results of a case study. Finally, we discuss the strengths and limitations of the test.

Investigación pediátrica española financiada: contribución de Anales de Pediatría a su difusión
2017
Resumen: Objetivo: Identificar la investigación pediátrica española financiada publicada en revistas generales pediátricas incluidas en la WoS (2010-2014) y la de Anales de Pediatría (AP). Explorar la relación de la financiación con el prestigio de las revistas y describir sus condiciones para cumplir los mandatos de acceso abierto. Material y método: La financiación de los artículos publicados en revistas pediátricas generales se identificó utilizando el campo Agencia Financiadora de la WoS y revisando el documento original para AP. Para AP se identificaron las entidades financiadoras de los AF y se valoró la diferencia en la citación de los AF y los no financiados mediante test no paramét…
Scientific networks and research groups development: educational Psychology case in Spain during the five-year periods 2004-2008 and 2009-2013
2017
El objetivo de este estudio ha sido identificar y conocer los cambios experimentados en los grupos de la comunidad científica de auto- res que trabajan en instituciones españolas y que publican artículos en las revistas científicas incluidas en la categoría "Psychology Educational" en la Web of Science durante el período 2004 hasta el 2013 y su pertenencia y perma- nencia en los diferentes grupos de investigación. Se realizó un estudio com- parativo de los grupos y su composición a lo largo de los quinquenios 2004- 2008 y 2009-2013. Los resultados indicaron que existe un incremento en el número de investigadores y de los grupos de investigación en el ámbito de la psicología educativa, que v…
Hidden connections: Network effects on editorial decisions in four computer science journals
2018
Abstract This paper aims to examine the influence of authors’ reputation on editorial bias in scholarly journals. By looking at eight years of editorial decisions in four computer science journals, including 7179 observations on 2913 submissions, we reconstructed author/referee-submission networks. For each submission, we looked at reviewer scores and estimated the reputation of submission authors by means of their network degree. By training a Bayesian network, we estimated the potential effect of scientist reputation on editorial decisions. Results showed that more reputed authors were less likely to be rejected by editors when they submitted papers receiving negative reviews. Although th…
Atlas of Variations in Medical Practice in Spain: The Spanish National Health Service under scrutiny
2012
Early in the 2000s, a countrywide health services research initiative was launched under the acronym of Atlas VPM: Atlas of Variations in Medical Practice in the Spanish National Health System. This initiative aimed at describing systematic and unwarranted variations in medical practice at geographic level-building upon the seminal experience of the Dartmouth Atlas of Health Care. The paper aims at explaining the Spanish Atlas experience, built upon the pioneer Dartmouth inspiration. A few selected examples will be used along the following sections to illustrate the outlined conceptual framework, the different factors that may affect variation, and some methodological challenges.
El aprendizaje basado en proyectos en el aula de música: una revisión sistemática
2021
El Aprendizaje Basado en Proyectos (ABP) es una de las metodologías de mayor expansión en las aulas actualmente. A pesar de no existir una definición unificada sobre el término, existe un consenso en torno a dos ideas: que el proyecto constituye el eje del currículo y que el alumno desarrolla una investigación. En música, la adopción de la etiqueta ABP es reciente, aunque los trabajos que relacionan música y proyectos son numerosos. La presente revisión identifica cuatro características comunes a los principales trabajos publicados: generación de una investigación, desarrollo de la práctica artística, planteamiento multidisciplinar y muestra pública del proyecto.
Effects of Exercise on the Airways
2012
In the last ten years, the effects of exercise on bronchial epithelial cells and inflammatory cells in the airways have been studied in detail, and such new information has been combined with previous knowledge on bronchial reactivity and asthma evoked by exercise in asthmatic patients and athletes. The resulting picture is very complex, and the potential clinical consequences are often contradictory, suggesting the opportunity to define different phenotypes of exercise-associated airway changes (Lee & Anderson, 1985; Haahtela et al., 2008; Moreira et al., 2011a). Studies in asthmatic athletes in the 90’ had began to explore the possibility that airway inflammation might be involved in exer…
