Prediction of the difficulty level in a standardized reading comprehension test : contributions from cognitive psychology and psychometrics
2013
Esta investigación busca identificar posibles variables predictoras del nivel de dificultad de los ítems de comprensión de lectura utilizados en una prueba psicométrica estandarizada para la admisión a una institución universitaria. Se propusieron varios posibles predictores del nivel de dificultad, a saber: densidad proposicional, negaciones, estructura sintáctica, dificultad del vocabulario, presencia elementos de realce (palabras resaltadas tipográficamente), abstracción del ítem y grado de similitud entre opción correcta y texto relevante para resolver el ítem. Mediante el Modelo Logístico Lineal de Rasgo Latente se encontró que la cantidad de proposiciones, la estructura sintáctica y, …
IRT Modeling of Decomposed Student Learning Patterns in Higher Education Economics
2019
Researchers have spent decades arguing how to measure improvements in learning within formal settings, where achievements are intended and presupposed, in a reliable and valid way. Repeated measures are required to investigate improvements of any kind. Students usually take a multiple-choice test at least twice with the difference between the two measurements indicating how much they have learned. Walstad and Wagner (J Econ Educ 47:121–131, 2016) presented a new approach to gathering more information about different learning patterns by decomposing these difference measures. They describe the patterns of positive learning (PL) and negative learning (NL), i.e., the development from not knowi…
Comparing speaking situations in three different language tests
2013
The purpose of this study was to compare learner outcome when five similar speaking situations were offered in the speaking subtest in Finnish, Swedish and English intermediate level tests in the Finnish National Certificates language testing system. The overall aim was to investigate the tasks by comparing learner outcomes across the three tests and to seek explanations for the outcome in the learners’ selfreported demographic, language, educational and professional background.The speaking situations were selected from the NC item bank meaning that they have undergone the Item Response Theory based analyses which indicate that the tasks function well in all tests. More information was need…
Assessing learners’ writing skills in a SLA study: Validating the rating process across tasks, scales and languages
2014
There is still relatively little research on how well the CEFR and similar holistic scales work when they are used to rate L2 texts. Using both multifaceted Rasch analyses and qualitative data from rater comments and interviews, the ratings obtained by using a CEFR-based writing scale and the Finnish National Core Curriculum scale for L2 writing were examined to validate the rating process used in the study of the linguistic basis of the CEFR in L2 Finnish and English. More specifically, we explored the quality of the ratings and the rating scales across different tasks and across the two languages. As the task is an integral part of the data-gathering procedure, the relationship of task p…
On the long-term response of elastic-perfectly plastic solids to dynamic cyclic loads
1992
It is shown that the long-term response of an elastic-perfectly plastic solid subjected to dynamic actions cyclically varying in time is characterized by stresses, plastic strain rates and velocities that are all periodic with the same period of the external actions, and are in perfect analogy with the quasi-static case; on the other hand, plastic strains and displacements are in general nonperiodic (except in case of alternating plasticity) and may increase indefinitely (except when elastic or plastic shakedown occurs). Besides, the work performed by the external actions in the steady cycle equals the work performed by the elastic stresses (i.e. pertaining to the elastic response of the bo…
Estimating sexual knowledge of people with mild intellectual disability through a valid and reliable assessment scale: The ISK-ID
2021
Background Despite the relevance of assessing sexual knowledge in people with Intellectual Disability, there is a lack of appropriate assessment tools to measure this domain. The current study tests the psychometric properties of the new ‘Inventory of Sexual Knowledge of people with Intellectual Disability’ (ISK-ID). Method 345 individuals with mild intellectual disability completed the ISK-ID before and after the implementation of a sexual education program. Psychometric properties of the ISK-ID were analysed according to Multidimensional Item Response Theory (MIRT). Results Its underlying factorial structure, along with parameters derived from the MIRT (item discrimination, difficulty, an…
Is It Possible to Measure the Role of the Bystander and the Victim of Bullying in Children? Construct Validity of Two Brief Pictorial Scales With IRT…
2021
The study's objective was to develop and validate the psychometric properties of two brief pictorial scales to evaluate the roles of bystanders and victims of bullying. A sample of 910 students was considered (49.6%, boys; 50.4%, girls) between the ages of 7 and 13 (M = 10, SD = 1.4). Both instruments present nine pictorial items representing two dimensions: physical bullying (items 1 to 4) and psychological bullying (items 5 to 9). An additional measure of anxiety was used to assess convergent validity. The Confirmatory Factorial Analysis shows that the two-dimensional oblique model, physical bullying and psychological bullying, presents a better fit to the bystander scale data (RMSEA = .…
Development and Validation of the ADAS Scale and Prediction of Attitudes Toward Affective-Sexual Diversity Among Spanish Secondary Students
2017
Violence against non-heterosexual adolescents in educational contexts remains a worrying reality, but no adequate attitudes toward affective-sexual diversity (AtASD) measure exists for Spanish adolescent students. We developed a 27-item scale including cognitive, affective, and behavioral aspects, which was completed by 696 secondary school students from the Madrid area. Factor analyses suggested a unidimensional model, Cronbach's alpha indicated excellent scale scores reliability, and item calibration under the item response theory framework showed that the scale is especially informative for homophobic attitudes. A hierarchical multiple regression analysis showed that variables traditiona…
The SF-8 Spanish Version for Health-Related Quality of Life Assessment: Psychometric Study with IRT and CFA Models.
2018
AbstractThe aim of current research is to analyze the psychometric properties of the Spanish version of the SF–8, overcoming previous shortcomings. A double line of analyses was used: competitivestructural equations modelsto establish factorial validity, andItem Response theoryto analyze item psychometric characteristics and information. 593 people aged 60 years or older, attending long life learning programs at the University were surveyed. Their age ranged from 60 to 92 years old. 67.6% were women. The survey included scales on personality dimensions, attitudes, perceptions, and behaviors related to aging. Competitive confirmatory models pointed out two-factors (physical and mental health…
Comparison of the brainstem auditory evoked responses during sevoflurane or alfaxalone anaesthesia in adult cats.
2017
Abstract Objective To compare the effects of general anaesthesia using sevoflurane or alfaxalone on the brainstem auditory evoked response (BAER) test in adult healthy cats. Study design Prospective, clinical, ‘blinded’, crossover study. Animals Ten feral adult healthy cats. Methods Premedication consisted of dexmedetomidine (0.01 mg kg –1 ) intramuscularly (IM). The first general anaesthesia was induced and maintained with sevoflurane (treatment S) for physical examination, BAER test, complete blood tests, thoracic radiographs and abdominal ultrasound. The second general anaesthesia was induced with alfaxalone (treatment A) IM (2 mg kg –1 ) and maintained with alfaxalone (10 mg kg –1 hour …
