How fast can we read in the mind? Developmental trajectories of silent reading fluency

The silent reading fluency is not an observable behaviour and, therefore, its evaluation is perceived as more challenging and less reliable than oral reading fluency. The present research is aimed to measure the silent reading speed in a sample of proficient students, assessed by an original silent reading fluency task, based on behavioural indicators of the silent reading speed. A total of 325 high school and university skilled students (age range 14–23 years) have been assessed using 3 tasks aimed to evaluate the oral reading speed (lists of words, lists of pseudowords and narrative text) and one task aimed to measure the silent reading speed. The average silent reading speed in our sample was around 12.5 syll/sec, almost double than the oral reading speed rate. The silent reading speed had an increase from 9.13 to 12.38 syll/sec from the first year of high school (ninth grade) to the fifth year of University. Conversely, the oral reading speed remained substantially unchanged for the entire academic course. Our results showed that the reading fluency in silent mode tends to increase up to the last years of University and it may be considered the most rapid and efficient reading mode. This study highlights the importance of including both silent and oral reading modes in the assessment of the older students and young adults, since silent reading is the main reading mode for proficient readers.     

Individual Differences in Childhood Behavior Disorders Associated With Epigenetic Modulation of the Cortisol Receptor Gene

Behavioral/emotional difficulties in children are the first sign of mental health problems. These problems are however, heterogeneous. A domain that may identify homogenous subgroups is hypothalamic–pituitary–adrenal function. This study tested whether epigenetic regulation of glucocorticoid receptor gene could explain the co‐occurrence of anxiety problems in children with behavior problems. Four‐ to 16‐year‐old clinically referred children (N = 241) were measured for psychiatric symptoms, methylation of target CpG sites in blood or saliva, and morning cortisol levels in those who gave blood. Increased methylation of promoter 1F CpG sites was associated with higher vulnerability to co‐occurring internalizing symptoms and morning cortisol. The results support increasing optimism that epigenetic regulation of key neuroendocrine systems might help explain hitherto unfathomable individual differences in susceptibility to psychiatric symptom profiles.     

Second Chance Programmes: a response to educational needs in compulsory education

This paper asks whether the integrated training provision currently offered through the different Spanish Second Chance Programmes (SCPs) constitutes a valid response to the educational needs and deficits known to exist among those young people who do not satisfactorily complete the Compulsory Secondary Education stage (ESO). The objectives of the current Social Guarantee Programmes (SGPs) are examined, as are the characteristics of the young people who participate in them. The Programmes of Initial Vocational Qualification (PCPI) envisaged in the most recent educational legislation are also discussed. Having identified the key factors which the empirical studies suggest influence the effectiveness of these programmes in addressing the educational needs and training deficiencies of the young people involved, a number of proposals are presented in connection with the training needs of teaching staff. The paper concludes with a number of proposals for improving the educational response to the challenges that the new perspectives and expectations raise for the development of a system of inclusive education to overcome the education deficits of the young people concerned.     

Teaching Modern Chemistry through ‘Recurrent Historical Teaching Models’

Today there are little more of 3 million chemist all over the world producing about 800,000 papers a year. They produce new substances – from some hundreds in 1800 to about 20 million now – the vast majority artificial. This rate is growing quite fast. Once the majority of chemistry teachers all over the world used textbooks as the main (sometimes the only) source of information, we became, without wanting to... history teachers! If ‘scientific literacy’ is the aim of science lessons in school, it is much more than the literacy now developed in science classrooms. It must include an understanding of the nature and process by which scientific activities are carried out. Recognition of the exponentially chemistry knowledge growth and the incompleteness of the current chemistry textbooks are thus intimately related to recognition of the need for recurrent historical teaching models.     

Models and methodology for simulating virtual enterprises in educational environment

This paper deals with a semester-long educational experience the authors led at the University of Calabria for reproducing current developments and uncertainties in real-world concurrent engineering, knowledge management practice and virtual enterprise organization. Students with different backgrounds (mechanical engineering, computer science engineering and management engineering) were selected in order to form a laboratory class and then were divided into many multidisciplinary teams. Such teams played different roles and were required to collaborate on the Web to simulate a virtual enterprise, which was aimed at designing virtual prototypes of average complexity articles. In addition to that, any team was involved in the construction of a knowledge base for codifying the explicit knowledge arising from the execution of technical and managerial tasks. The paper deals with models, methodologies and technologies that have been used in this laboratory experience and, moreover, it describes an approach for simulating, in an educational environment, some aspects of the behaviour of virtual enterprises generated by a virtual organization.     

Effects of plyometric jump training in female soccer player’s vertical jump height: A systematic review with meta-analysis

ABSTRACT

To assess the effects of plyometric jump training (PJT) in female soccer player’s vertical jump height, a review was conducted using the data sources PubMed, MEDLINE, Web Of Science and SCOPUS. Only peer-review articles were included. To qualify for inclusion in the meta-analysis, studies must have included (i) a PJT programme of at least 2 weeks, (ii) cohorts of healthy female soccer players with no restriction for age, (iii) a control group, (iv) a measure of countermovement jump (CMJ). The inverse variance random-effects model for meta-analyses was used. From 7,136 records initially identified through database searching, 8 were eligible for meta-analysis, comprising 9 training groups (n = 99) and 9 control groups (n = 94). The magnitude of the main effect was moderate (ES = 1.01 [95%CI = 0.36–1.66], Z = 3.04, p = 0.002). Sub-group analyses were performed (i.e., PJT frequency, duration and total number of sessions), revealing no significant subgroup differences (p = 0.34–0.96). Among the studies included in this review, none reported injury or other adverse effects. In conclusion, PJT is effective in female soccer players for the improvement of vertical jump height. In future, research must identify specific dose–response relationships following PJT, particularly in the long term.
