A mobile game as a support tool for children with severe difficulties in reading and spelling
2020
We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading …
GraphoLearn SI : Digital learning support for reading difficulties in a transparent orthography
2020
Recognition of the importance of evidence-based technological tools that provide personalized learning opportunities is growing. This paper reports on a pilot study evaluating GraphoLearn for Standard Indonesian, a digital game environment that trains basic reading skills by extensive-but-playful exposure to grapheme–phoneme correspondences. The results obtained from 33 Indonesian first graders show that game progress was found to be a significant predictor of reading and decoding abilities both at the posttest and the 5-month follow-up assessment. Our results additionally indicated a significant interaction effect of game progress and letter–sound knowledge at posttest: Progress in the gam…
Junkbox, a waste management educational game for preschool kids
2019
Waste management is becoming an increasingly important issue in contemporary society. The growth in consumption, the increase in urbanization and economic development have as main consequence an increase in the production of waste. Moreover, the population's bad recycling habits are becoming more and more entrenched. In this context, sustainable development has gained considerable importance and the need to teach new generations the value of protecting the environment is key and what through our research we are experimenting is the way of playing. In fact, basic but very significant behaviours can be activated through a game and they may become stable habits and then proper lifestyles. This…
Expanding the Variety of Zirconium‐based Inorganic Building Units for Metal–Organic Frameworks
2019
Two new zirconium-based metal-organic frameworks with the composition [Zr6 O4 (OH)4 (OAc)6 (BDC)3 ] (CAU-26) and [Zr5 O4 (OH)4 (OAc)4 (BDC)2 ] (CAU-27) are reported, which were synthesized from acetic acid, a rarely utilized but green and sustainable solvent (BDC2- : 1,4-benzenedicarboxylate). Structure determination aided by automated electron diffraction tomography revealed that CAU-26 is composed of layers of well-known {Zr6 O8 } clusters interconnected by terephthalate ions. In contrast CAU-27 exhibits a three-dimensional structure with a so far unknown type of one-dimensional inorganic building unit (IBU), which can be rationalized as condensed polyhedron-sharing chains of {Zr6 O8 } cl…

Effectiveness of a Physical Education Program on the Motor and Pre-literacy Skills of Preschoolers From the Training-To-Health Project: A Focus on We…
2020
Many studies reported a positive relationship between motor skills, cognitive functions, and school performance in school-age children; however, little is known in preschool children. The aim of the present study was to demonstrate the effectiveness of a physical education program (PEP) on locomotor, object control skills, and pre-literacy cognitive functions in a wide population of preschoolers and verify whether weight status could influence these abilities. In the context of the Training-to-Health Project, a sample of 1,029 preschoolers was recruited in kindergartens from the urban area of Palermo (Italy). Their gross motor and pre-literacy skills were tested before (PRE) and after (POST…
Análisis del proceso migratorio de las familias colombianas en España
2014
espanolSe analiza la migracion como proceso centrado en la familia transnacional, segun relato de sus protagonistas: migrantes - padres e hijos - y familiares en Colombia. Se parte del modelo sistemico y de la metodologia de la Grounded-Theory. El proceso se desencadena por una combinacion de factores de empuje y de llamada; los pioneros, mayoritariamente mujeres, poseen un perfil muy variado. Destaca la dificultad de sus primeras experiencias, que mejoran gracias a sus apoyos externos y a su teson. A pesar de las dificultades del proceso de aculturacion, el balance realizado es positivo, sobre todo por la esperanza puesta en los hijos, que tras las dificultades iniciales desean permanecer …
Ruthenium-arene complexes bearing naphthyl-substituted 1,3-dioxoindan-2-carboxamides ligands for G-quadruplex DNA recognition.
2019
Quadruplex nucleic acids – DNA/RNA secondary structures formed in guanine rich sequences – proved to have key roles in the biology of cancers and, as such, in recent years they emerged as promising targets for small molecules. Many reports demonstrated that metal complexes can effectively stabilize quadruplex structures, promoting telomerase inhibition, downregulation of the expression of cancer-related genes and ultimately cancer cell death. Although extensively explored as anticancer agents, studies on the ability of ruthenium arene complexes to interact with quadruplex nucleic acids are surprisingly almost unknown. Herein, we report on the synthesis and characterization of four novel Ru(…
An exploration of self-awareness among shy adolescents
2009
The aim of this article is to explore the concept of self-awareness related to adolescents with shyness as an emotional and behavioural problem at school. In its extreme form shyness can be seen as an emotional and behavioural problem that interferes with an individual’s potential for growth, learning and overall well-being. Self-awareness is a rather ambiguous term, and psychological, philosophical and neuro-scientific literature discuss the term from different angles that are relevant for this group of adolescents. During interviews and observations in school, 15 adolescents presented their experiences and challenges. Their narratives are the foundation for a discussion related to self-a…
The development of phonological abilities and their relation to reading acquisition: case studies of six Finnish children.
1999
The relation between phonological abilities and reading acquisition and the interindividual variation in the development of different phonological manipulation skills were assessed for six 7-year-old Finnish nonreaders. Intensive time series data were collected by following the children for 13 months. Assessments were conducted every 4 weeks with five phonological manipulation tests. The results indicated gradual progress at the group level. However, analysis of the individual profiles indicated large interindividual variation in the rate of improvement and in the relation between different manipulation skills and reading acquisition.
