An Examination of the LVA Approach to Teaching Reading

The Language Vocabulary Acquisition (LVA) Approach is a revolutionary method of reading instruction for emergent and developing readers. It is an intense reading program with high levels of student participation, engagement, and interaction with print text, that yields high outcomes in phonological awareness, reading and writing fluency, and comprehension. The LVA Approach quickly immerses young African-American children into print text, bombarding them with a preponderance of new words, ideas, and general understandings about their surroundings and the world in general. This approach enables them to develop expansive word knowledge, resulting in reading, writing, and thinking competencies at or above their grade level and national norms. This approach focuses on the printed text—words, words, and more words—rather than visual images, picture clues, and illustrations.

Research studies on literacy development supported the use of printed text in children's initial efforts in reading (Gough and Hillinger 1980). Words, word constructions, and vocabulary development are the beginning steps to the LVA Approach. Children are able to take the skills learned in the LVA Approach and apply them to children's literature and standard basal reading texts. The LVA Approach was developed by Angela L. Davis who successfully introduced it to her first-grade class during the 2000–2001 school year. This article describes a three-year pilot effort to improve the reading competencies of primary-age children at Bouchet Academy, a Chicago Public School (CPS) located on the southeast side of the city.     

High-tech,hard work: an investigation of teachers’ work in the digital age

This paper explores the ways in which digital technologies are now implicated in the work – and specifically the labour – of school teachers. Drawing upon qualitative studies in two Australian high schools, the paper examines the variety of ways in which teachers’ work is now enacted and experienced along digital lines. In particular, the paper highlights the association of digital technologies with the standardization, evidencing, intensification and altered affect of teachers’ work. The paper questions the extent to which these trends might be seen as constituting ‘new’ forms of labour, with the research data pointing to continuities and disjunctures in terms of teachers’ autonomy and professionalization. The paper also considers how these conditions are experienced in different ways across the teaching workforce. The paper concludes by reflecting on how fairer and/or empowering working conditions might be achievable through alternate uses of digital technology.     

Practice, instruction and skill acquisition in soccer: challenging tradition

The acquisition of soccer skills is fundamental to our enjoyment of the game and is essential to the attainment of expertise. Players spend most of their time in practice with the intention of improving technical skills. However, there is a lack of scientific research relating to the effective acquisition of soccer skills, especially when compared with the extensive research base on physiological aspects of performance. Current coaching practice is therefore based on tradition, intuition and emulation rather than empirical evidence. The aim of this review is to question some of the popular beliefs that guide current practice and instruction in soccer. Empirical evidence is presented to dispel many of these beliefs as myths, thereby challenging coaches to self-reflect and critically evaluate contemporary doctrine. The review should inform sports scientists and practitioners as to the important role that those interested in skill acquisition can play in enhancing performance at all levels of the game.     

Exercise training and impaired glucose tolerance in obese humans

Individuals with impaired glucose tolerance (IGT) are at greater risk of developing diabetes than in normoglycaemia. The aim of this study was to examine the effects of 12-weeks exercise training in obese humans with IGT. Eleven participants (6 males and 5 females; 49±9 years; mean Body Mass Index (BMI) 32.4 kg · m(-2)), completed a 12-week brisk walking intervention (30 min per day, five days a week (d · wk(-1)), at 65% of age-predicted maximal heart rate (HR(max)). Anthropometric measurements, dietary intake, pulse wave velocity (PWV, to determine arterial stiffness) and blood pressure (BP) were examined at baseline and post intervention. Fasting blood glucose, glycosylated haemoglobin, insulin, blood lipids, indices of oxidative stress and inflammation (lipid hydroperoxides; superoxide dismutase; multimeric adiponectin concentration and high-sensitivity C-reactive protein) were also determined. Post intervention, PWV (9.08±1.27 m · s(-1) vs. 8.39±1.21 m · s(-1)), systolic BP (145.4±14.5 vs. 135.8±14.9 mmHg), triglycerides (1.52±0.53 mmol · L(-1) vs. 1.31±0.54 mmol · L(-1)), lipid hydroperoxides (1.20±0.47 μM · L(-1) vs. 0.79±0.32 μM · L(-1)) and anthropometric measures decreased significantly (P < 0.05). Moderate intensity exercise training improves upper limb vascular function in obese humans with IGT, possibly by improving triglyceride metabolism, which may subsequently reduce oxidative stress. These changes were independent of multimeric adiponectin modification and alterations in other blood biomarkers.     

Characteristics of the start in women's World Cup skeleton

This study characterizes key elements of the start in elite female World Cup skeleton athletes. The top 20 female competitors in three World Cup races were videotaped within a calibrated space to allow the following components of the start to be quantified: (1) acceleration (velocity at 15-m mark, time to 15-m mark), (2) capacity (time to load, total number of steps to load), and (3) load (velocity at 45-m mark). A correlation analysis was used to establish the relationship between the variables of interest and overall start time (15- to 65-m mark). Velocity at the 15-m mark accounted for 86% of the variance in overall start time at St. Moritz and 85% at Sigulda. A stepwise regression analysis revealed that approximately 89% of the variation in start time could be explained by velocity at the 15-m mark, time to load, and velocity at the 45-m mark. Of the variables analysed in this study, rapid acceleration to attain a high velocity at the 15-m mark was the most important component of a fast overall start time. The importance of the time to load and velocity at the 45-m mark vary according to the different track characteristics.
