Distractor Efficiency in an Item Pool for a Statistics Classroom Exam: Assessing Its Relation With Item Cognitive Level Classified According to Bloom…
2018
Multiple-choice items are one of the most commonly used tools for evaluating students’ knowledge and skills. A key aspect of this type of assessment is the presence of functioning distractors, i.e., incorrect alternatives intended to be plausible for students with lower achievement. To our knowledge, no work has investigated the relationship between distractor performance and the complexity of the cognitive task required to give the correct answer. The aim of this study was to investigate this relation, employing the first three levels of Bloom’s taxonomy (Knowledge, Comprehension, and Application). Specifically, it was hypothesized that items classified into a higher level of Bloom’s class…
Loneliness and its relation to mental health in the general population: Validation and norm values of a brief measure
2021
Abstract Background Loneliness has been increasingly recognized as an important determinant of mental health. The purposes of this study were to (1) determine the degree of loneliness of women and men across different age groups, (2) explore its association with distress, (3) psychometrically evaluate the Three-Item Loneliness Scale, (4) provide norm values. Methods The Three-Item Loneliness Scale was applied in a representative survey of the German population (N=2527; 14–95 years). Standardized scales were used measuring distress (depression and anxiety symptoms, perceived stress, hopelessness, suicidal ideation, fatigue, life satisfaction). Factor structure and measurement invariance acro…
Item Response Trees: a recommended method for analyzing categorical data in behavioral studies
2015
Behavioral data are notable for presenting challenges to their statistical analysis, often due to the difficulties in measuring behavior on a quantitative scale. Instead, a range of qualitative alternative responses is recorded. These can often be understood as the outcome of a sequence of binary decisions. For example, faced by a predator, an individual may decide to flee or stay. If it stays, it may decide to freeze or display a threat and if it displays a threat, it may choose from several alternative forms of display. Here we argue that instead of being analyzed using traditional nonparametric statistics or a series of separate analyses split by response categories, this kind of data ca…
Estudio del espesor óptico de nubes a partir de radiación solar
2015
El objetivo general de este trabajo es el cálculo del espesor óptico de nubes para nubes bajas y medias formadas por gotas de agua en la ciudad de Burjassot (Valencia), mediante un método de minimización. Los espesores han sido obtenidos tanto para cielos cubiertos como para cielos parcialmente nubosos con el Sol oculto por las nubes, a partir de medidas de irradiancia eritemática (UVER) e irradiancia solar total a nivel de suelo. Para ello se han utilizado dos modelos de transferencia radiativa que presuponen capas de nubes homogéneas plano-paralelas. También se han obtenido diferentes relaciones empíricas entre el espesor óptico de nubes obtenido y diferentes factores de transmisividad at…

Puheen ymmärtämisen tehtävien taitotasoille asettaminen Yleisissä kielitutkinnoissa
2016
The aim of this study is to explore rater effects, such as consistency and severity of the judgements of 12 expert judges, and to report the extent of assessment criteria used by them. The data of the study are based on the three different phases of the standardization procedure which were analyzed using the MFRM model. In addition, feedback gathered from the expert judges was used to find out their opinions about the procedure and to validate the results of the standardization. The results of this study indicate that general discussion on and statistical information about the items influenced judges’ consistency and severity and their adaptation of the assessment criteria. The judges thems…
Influencia del tiempo de ligadura del cordón umbilical en la morbilidad secundaria neonatal y los depósitos de hierro en el neonato
2022
El déficit de hierro es el déficit nutricional más frecuente a nivel mundial y constituye un importante problema de salud pública, principalmente en los países más desfavorecidos. La causa más frecuente de anemia en el mundo es la deficiencia de hierro. Los períodos críticos donde los requerimientos son elevados son el primer año de vida, la adolescencia y el embarazo. El pinzamiento demorado aumenta los depósitos de hierro en los RN, que les garantiza una disponibilidad de este mineral durante los primeros meses de vida, periodo crucial del desarrollo de múltiples sistemas como el SNC. , pero también se le se asoció con un aumento de la policitemia neonatal, ictericia patológica con necesi…

Discovering Gender-Specific Knowledge from Finnish Basic Education using PISA Scale Indices
2014
The Programme for International Student Assessment, PISA, is a worldwide study to assess knowledge and skills of 15- year-old students. Results of the latest PISA survey conducted in 2012 were published in December 2013. According to the results, Finland is one of the few countries where girls performed better in mathematics than boys. The purpose of this work is to refine the analysis of this observation by using education data mining techniques. More precisely, as part of standard PISA preprocessing phase certain scale indices are constructed based on information gathered from the background questionnaire of each participating student. The indices describe, e.g., students’ engagement, dri…
