Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
2013
Different spatial distributions of optical vortices have been generated and characterized by implementing arrays of devil's vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the preferred position and topological charge value to each vortex in the structure, tuning the desired angular momentum. Distributions with charges and momenta of the opposite sign have been experimentally demonstrated. The angular velocity exhibited by the phase distribution around the focal plane has been visualized, showing an excellent agreement with the simulations. The practical limits of the method, with interest for applications involving particle transfer and manipula…
Where lol is: function and position of lol used as a discourse marker in YouTube comments
2020
Lol is probably one of the most popular words in computer-mediated communication. It is generally taken to be the acronym of “laughing out loud”, but it is not always used to indicate a humorous response; rather, it is multifunctional. Drawing on previous studies of the different functions of lol, this paper explores a possible correlation between the position and function of non-lexicalized lol in the specific context of YouTube comments. The hypothesis is that the function of lol largely depends on its position: clause-initial lol is not used with the same functions as clause-final lol. The data for the study come from the comment threads of three popular YouTube videos posted in 2017, 20…
The role of achievement beliefs and behaviours in spontaneous reading acquisition
2006
Abstract This study examined the role of motivational or attitudinal factors, such as achievement beliefs and behaviours, in learning to read before receiving formal instruction. A total of 200 Finnish children were examined at ages 5 and 6½. Half of them ( n = 107) had a familial risk for dyslexia. The results showed that those children who were verbally skilful at age 5 showed a higher level of task-focused behaviour at age 6½. This task-focused behaviour then contributed to spontaneous reading acquisition. The impact of previous verbal skills on spontaneous reading acquisition was mediated in part by achievement behaviour.
Assessing dyslexia in Finnish high-school students: a pilot study
2000
A pilot study concerning Finnish dyslexics at senior high school (lukio), for 16–19-year-olds, is reported. The phonological processing deficit was assumed to underlie dyslexia in these late teenage subjects. The regular nature of Finnish orthography was taken into consideration. Four tasks were introduced to a total of 32 students, of whom 15 were dyslexics and 17 were controls. The controls outperformed the dyslexics on three tasks: text recoding, pseudoword recoding and pseudoword spelling. On the text spelling task, both groups performed equally well. In the correlational analysis of all subjects, both recoding tasks showed high correlations with selfestimated school achievement in lang…
An Analysis of a Single Case of Comorbidity between Learning Disability and Borderline Intellectual Functioning
2012
Abstract In this study we explored a case of comorbidity between DSA and Borderline Intellectual Functioning. The girl was fourteen years old, ninth grade of school in Palermo, with significant learning difficulties. Two interviews were conducted, one with parents and one with teachers, to investigate the history of the girl's learning. In the pre-test phase the following cognitive areas were investigated: Q.I. (Level of Intelligence), decoding ability, reading comprehension and writing skills. Motivational-emotional profile was also evaluated: school motivation, self-handicapping strategies, self esteem and school anxiety. To assess these cognitive areas we used: Reading Comprehension Test…
Reading comprehension in French 1st and 2nd grade children: Contribution of decoding and language comprehension
2006
This paper reports a study conducted with French first-grade and second-grade children (mean age: 6;8 and 7;8 respectively). The first aim was to re-examine the Gough and Tunmer’s (1986) Simple View in assessing the specific contribution of decoding ability and language comprehension to reading comprehension. The second one was to analyse the difficulties of children in reading comprehension. Reading and listening comprehension were assessed using both visual and auditory version of the same test. Decoding ability was assessed by means of a nonword reading test. On the basis of reading comprehension scores, skilled and less skilled comprehenders were contrasted, and then two groups of less …
The relationship between children‘s reading ability, verbal and fluid intelligence and measurements of eye movements during reading
2014
The aim of this study was to clarify, which of the following two measures: verbal intelligence or measurements of eye movements, is better predictor of reading ability. In addition, the study also investigated the relationships between reading ability, fluid intelligence and measurements of eye movements. Participants of the study (N = 28; mean age = 8.80; SD = .41; 54% boys) were assessed in reading with LMST-I Reading achievement test, verbal and fluid intelligence was measured using two scales – Verbal Comprehension and Perceptual reasoning – from Latvian edition of Wechsler Intelligence Scale for Children Fourth Edition (WISC- IV, Latvian version), as well as eye tracking was made durin…
Emotional correlates of body weight: The moderating effects of gender and family income
2011
Abstract This study explored emotional correlates of relative body weight in a sample of 187 male and 269 female college students. The contribution of relative body weight, gender, family income and their interactions to variables related to anxiety and anger were evaluated by multiple regression procedures. Relative body weight was positively related to trait anxiety, especially among those with lower family incomes. Increased body weight was also related to trait anger and an anger-out expression style, but only among men. These results suggest that gender and family income moderate the contribution of relative body weight to anxiety and anger, both central aspects of a 'disease-prone per…
Computer-Assisted Reading and Spelling Intervention with Graphogame Fluent Portuguese
2018
Learning to master reading and spelling can be assisted by communication technologies, ever more common among children. The aim of this study was to investigate whether a new science-based computer-assisted intervention could improve reading and spelling in 2nd graders at risk to fail literacy acquisition. Participants were 7-year-old monolingual children identified as having reading difficulties in their native language, Portuguese. Following neurocognitive assessment, the children were divided into two matched groups (N = 15 × 2), one to be trained with Graphogame Fluent Portuguese that we developed (target intervention) and the other with an analogous Graphogame in mathematics (control i…
