Educación XX1 : revista de la Facultad de Educación
2017
Resumen basado en el de la publicación Título, resumen y palabras clave también en inglés El rendimiento dispar encontrado en algunos países del informe PISA 2009 (OECD, 2010) entre textos continuos y no-continuos en tareas de competencia lectora, así como la naturaleza y estructura diferente de la información textual, han motivado el estudio del procesamiento on-line de ambos tipos de texto con el objetivo de explorar qué sucede cuando se usan para responder preguntas. Se analizan las decisiones estratégicas de relectura de textos continuos y no-continuos en tareas de competencia lectora similares a las de PISA, así como la estabilidad en el uso de esta estrategia. Para ello, se aplicaron …
¿Tiene sentido seguir distinguiendo entre aprendizaje de conceptos, resolución de problemas de lápiz y papel y realización de prácticas de laboratori…
2021
Nuestra pretensión en este trabajo es cuestionar la distinción clásica entre «teoría», «prácticas de laboratorio» y «problemas». Intentaremos mostrar qué investigaciones realizadas en los tres campos privan de sentido a esta separación que, conviene notar, no guarda paralelismo alguno con la actividad científica real. Our aim with this paper is to question the typical distinction between «theory», «lab» and «paper and pencil problem-solving » activities. We intend to show that research done on these domains does not support their separation in the teaching/learning process. In fact, this separation does not take place in any real scientific activity.
Validation and Measurement Invariance of the Scale of Positive and Negative Experience (SPANE) in a Spanish General Sample
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/1660-4601/17/22/8359 Este artículo pertenece a la sección "Health behavior, chronic disease and health promotion". Well-being has been measured based on di erent perspectives in positive psychology. However, it is necessary to measure a ects and emotions correctly and to explore the independence of positive and negative a ect. This cross-sectional study adapts and validates the Scale of Positive and Negative Experience (SPANE) with a non-probabilistic sample of 821 Spanish adults. A confirmatory factor analysis confirmed two related factors with two correlated errors. The average variance extracted was 0.502 for…
Psychometric Properties of the “Alcohol Consumption Consequences Evaluation” (ACCE) Scale for Young Spanish University Students
2020
Instruments that evaluate alcohol use consequences among young people do not consider the intensive alcohol consumption pattern that is so characteristic during these ages. Some of these instruments are even ineffective in the Spanish population. Hence the interest in developing an instrument more adapted to the reality of our young people. A total of 601 university students (35.9% male and 64.1% female) from 18 to 20 years old were recruited. All of them answered a total of 77 items obtained from the review of both the scientific literature and the different scales used to measure consequences derived from alcohol consumption. In addition, they completed the AUDIT and the Timeline Followba…
Étude de l’évolution du potentiel génétique de populations bactériennes dégradant l’atrazine
2011
17 pages de références bibliographiques et 20 pages d'annexes; L’atrazine, un des herbicides les plus utilisés pour contrôler le développement des plantes adventices dans les cultures, a conduit à la contamination de l’environnement. L’exposition chronique à cet herbicide a conduit à l’émergence de populations microbiennes du sol capables de dégrader l’atrazine et de l’utiliser comme une source d’azote pour leur croissance. Ces populations microbiennes sont responsables de la biodégradation accélérée (BDA) de l’atrazine, un service écosystémique contribuant à diminuer la persistance de cet herbicide dans l’environnement. L’objectif de ce travail était d’étudier les mécanismes génétiques et …
Reliable Correlational Cuing While Controlling for Most-Recent-Pairing Effects.
2020
Irrelevant aspects of the environment or irrelevant attributes of task-relevant stimuli can have important and reliable effects on behavior. When the specific values of an irrelevant stimulus attribute are correlated with different responses, a correlational-cuing effect is observed: faster and more accurate responses when the correlation is positive than when it is negative. Previous work has shown that this effect is not due to simple differences in how often the specific stimuli are being presented, and most explanations of the effect have stressed the clear parallels with classical associative learning. Very recently, however, evidence in favor of an alternative model has been presented…
The Australian Sheep-Goat Scale: An Evaluation of Factor Structure and Convergent Validity.
2018
The Australian Sheep-Goat Scale (ASGS) is a commonly used measure of belief in the paranormal. The scale contains items that index extrasensory perception (ESP), psychokinesis (PK), and life after death (LAD). Although, research employs the ASGS as both a general (unidimensional) and factorial (multidimensional) measure, few studies have examined the appropriateness of these solutions. Accordingly, the present paper tested the psychometric integrity of the ASGS via two studies. Study 1 assessed ASGS factorial structure using confirmatory factor analysis. To achieve this, merging of ASGS data from previously published studies and ongoing work created a heterogeneous sample of 1,601 responses…
An Evaluation of the Belief in Science Scale
2019
The Belief in Science Scale (BISS) is a unidimensional measure that assesses the degree to which science is valued as a source of superior knowledge. Due to increased academic interest in the concept of belief in science, the BISS has emerged as an important measurement instrument. Noting an absence of validation evidence, the present paper, via two studies, evaluated the scale’s factorial structure. Both studies drew on data collected from previous research. Study 1 (N = 686), using parallel analysis and exploratory factor analysis, identified a unidimensional solution accounting for 56.43% of the observed variance. Study 2 (N = 535), using an independent sample, tested the unidimensional …
The Binge Eating Scale: Structural Equation Competitive Models, Invariance Measurement Between Sexes, and Relationships With Food Addiction, Impulsiv…
2019
Introduction: The Binge Eating Scale (BES) is a widely used self-report questionnaire to identify compulsive eaters. However, research on the dimensions and psychometric properties of the BES is limited. Objective: The aim of this study was to examine the properties of the Spanish version of the BES. Methods: Confirmatory Factor Analyses (CFAs) were carried out to verify the BES factor structure in a sample of Spanish college students (N = 428, 75.7% women; age range = 18–30). An invariance measurement routine was carried out across sexes, the latent means were compared, and estimates of reliability and convergent and discriminant validity were presented. Results: A one-factor model fit the…
Effects of Grammatical Structure of Compound Words on Word Recognition in Chinese
2018
Two lexical priming experiments were conducted to examine effects of grammatical structure of Chinese two-constituent compounds on their recognition. The target compound words conformed to two types of grammatical structure: subordinate and coordinative compounds. Subordinate compounds follow a structure where the first constituent modifies the second constituent (e.g., , meaning snowball); here the meaning of the second constituent (head) is modified by the first constituent (modifier). On the other hand, in coordinative compounds both constituents contribute equally to the word meaning (e.g., , wind and rain, meaning storm where the two constituent equally contribute to the word meaning).…
