Improving Reading to Improve Math

Reading provides information across the curriculum. Thus, to the extent that fundamental (i.e., generalizable) reading comprehension strategies can be taught, the benefits should be found in multiple domains. To test this claim, children in the third and fourth grades read by simulating text content using the two-part, embodied Moved by Reading intervention. While reading six initial texts, children literally manipulated pictures on a computer screen to simulate sentence content; next, for additional texts the children imagined the manipulation of the pictures. These additional texts were in the form of mathematical story problems. Compared to a control condition, children using Moved by Reading solved more problems correctly, and this improvement is mainly attributed to a 35% reduction in the use of irrelevant numerical information in solution attempts. Thus, Moved by Reading teaches a fundamental strategy that encourages the sense-making that can aid mathematical story problem solution.     

Building on similarity: a whole class use for simplified language materials

This article examines how the recommended pedagogy for people with Down syndrome may be of use to a wide range of other individuals within a mainstream school setting. Drawing on current practices within English education, it describes the evidence behind the current advice about the language to be used in materials for people with Down syndrome, and then examines why similar language forms have been devalued as teaching tools in relation to people who are learning English as an additional language. The article then describes the use of differentiated materials in a secondary school and the problems that this both highlights and generates. Drawing on these three strands, as well as current best practice and research into comprehension and simple English, this article then proposes a possible usage for simplified language materials (SLMs) at transition points of lessons. It suggests that if SLMs are used at these specific moments within lessons they could be of value to the whole class, and serve as a useful inclusive pedagogy. The article highlights the need for further research into the possible use of SLMs within mainstream schools.     

Two tests of approach-iron golf skill and their ability to predict tournament performance

Abstract

The aim of this study was to investigate the convergent and predictive validity of two skill tests that examine the ability of golfers to hit accurate approach-iron shots. Twenty-four high-level golfers (handicap = 2.6 ± 1.7) performed the Nine-Ball Skills Test (assesses the ability to shape/control ball trajectory with high accuracy) and the Approach-Iron Skill Test (assesses the ability to hit straight shots from varying distances with high accuracy). Participants then completed at least eight rounds of tournament golf over the following 90 days and reported an indicator of approach-iron accuracy (per cent error index). A moderate correlation (r = 0.50, P < 0.05) was noted between scores for both tests. Generalised estimating equations, using two covariates (lie of the ball and distance to hole), were used to determine model fit and the amount of variance explained for tournament per cent error index. Results showed that the Approach-Iron Skill Test was the slightly stronger predictor of on-course per cent error index. With both test scores considered together, a minimal amount of additional variance was explained. These findings suggest that either of the tests used individually or combined may be used to predict tournament approach iron performance in high-level golfers.     

The effects of caffeine ingestion on performance time,speed and power during a laboratory-based 1 km cycling time-trial

Abstract

There is little published data in relation to the effects of caffeine upon cycling performance, speed and power in trained cyclists, especially during cycling of ～60 s duration. To address this, eight trained cyclists performed a 1 km time-trial on an electronically braked cycle ergometer under three conditions: after ingestion of 5 mg · kg^?1 caffeine, after ingestion of a placebo, or a control condition. The three time-trials were performed in a randomized order and performance time, mean speed, mean power and peak power were determined. Caffeine ingestion resulted in improved performance time (caffeine vs. placebo vs. control: 71.1 ± 2.0 vs. 73.4 ± 2.3 vs. 73.3 ± 2.7 s; P = 0.02; mean ± s). This change represented a 3.1% (95% confidence interval: 0.7–5.6) improvement compared with the placebo condition. Mean speed was also higher in the caffeine than placebo and control conditions (caffeine vs. placebo vs. control: 50.7 ± 1.4 vs. 49.1 ± 1.5 vs. 49.2 ± 1.7 km · h^?1; P = 0.0005). Mean power increased after caffeine ingestion (caffeine vs. placebo vs. control: 523 ± 43 vs. 505 ± 46 vs. 504 ± 38 W; P = 0.007). Peak power also increased from 864 ± 107 W (placebo) and 830 ± 87 W (control) to 940 ± 83 W after caffeine ingestion (P = 0.027). These results provide support for previous research that found improved performance after caffeine ingestion during short-duration high-intensity exercise. The magnitude of the improvements observed in our study could be due to our use of sport-specific ergometry, a tablet form and trained participants.     

The Effect of Bicycle Ergometer Exercise at Varying Intensities on the Heart Rate,EMG and Mood State Responses to a Mental Arithmetic Stressor

Abstract

The purpose of this study was to examine the effect of bicycle ergometer exercise at varying metabolic intensities upon the heart rate, electromyographic (EMG), and mood state responses to a timed mental arithmetic stressor. Twelve males participated in four experimental conditions: three exercise trials consisting of workloads of 40%, 55%, and 70% of physical work capacity, and an attentional control condition. Daily test protocol involved the following time sequence: habituation, baseline, exercise or control condition (presented in a counterbalanced order), recovery, mental arithmetic, and completion of mood state questionnaire. Results indicated no differential response to the mental arithmetic stressor across the four conditions for the 12 subjects for heart rate, EMG activity, or mood state. Thus, 15 min of exercise at 40%, 55%, and 70% of physical work capacity proved to be no different from an attentional control condition in influencing the physiological and psychological responses to the mental arithmetic stressor.     

The effects of carbohydrate ingestion on the badminton serve after fatiguing exercise

Abstract

The badminton serve requires great skill and may be affected by fatigue. The aim of the present study was to determine whether carbohydrate ingestion affects badminton performance. Nine male badminton players (age 25 ± 7 years, mass 80.6 ± 8.0 kg) attended the laboratory on three occasions. The first visit involved an incremental exercise test to exhaustion to determine peak heart rate. Participants were given 1 L of a carbohydrate-electrolyte drink or a matched placebo during the experimental trials. The accuracy of 10 long and 10 short serves was determined before and after exercise. The fatiguing exercise was 33 min in duration (83 ± 10% and 84 ± 8% peak heart rate for the placebo and carbohydrate trial respectively). Capillary blood samples (20 μL) were taken before and after exercise for determination of blood glucose and lactate. There was deterioration in long serve accuracy with fatigue (P = 0.002), which carbohydrate ingestion had a tendency to prevent (P = 0.077). There was no effect of fatigue (P = 0.402) or carbohydrate ingestion (P = 0.109) on short serve accuracy. There was no difference in blood glucose concentration between trials (P = 0.851). Blood lactate concentration was higher during the placebo trial (P = 0.016). These results suggest that only the long serve is influenced by fatigue and carbohydrate had a tendency to prevent the deterioration in performance.     

The Decline of Mass Sport Provision in the German Democratic Republic

The German Democratic Republic's sports system, often termed a ‘sports miracle’, produced outstanding results in international sport. Drug abuse aside, this system appeared to be based on a robust and symbiotic relationship with mass sport, which was amply provided for by the state. Using unpublished letters sent by GDR citizens to the state authorities drawn from the Federal Archive in Berlin, this article sheds light on the miserable state of mass sport, particularly in the last decade of the state's existence. Although great numbers of East Germans took part in some form of sport or the other, elite sport – and the privileged facilities and equipment that went with it – was effectively hermetically sealed off from wider society. The impressive upward trajectory of GDR sport – in terms of international titles and Olympic medals won – went hand in hand with the decline in standards of facilities and availability of equipment for the masses.     

The Emergence and Transformations of the World Cup for the Homeless: From the Excitement of Soccer to Managerial Decisions between 2003 and 2012

Abstract

An international football-soccer tournament was initiated for socially excluded homeless individuals in July 2003 and has been held ever since, growing annually in terms of size, competing delegations, media attention and corporate involvement. The aim of the paper is to analyze the initial, historical, journey of this World Cup from its conceptual formation until the end of its first decade (2003–2012). The paper looks particularly at the efforts involved in bringing the concept to life and the challenges the organizers faced before achieving the annual frequency of an event dedicated for wider social purposes. However, also discussed is the use of competitive football formats and the organization of the competition for male and female players. As the tournament has become more successful, it is argued that its overall aim of proposing tools beyond sport for homeless people has been displaced in certain ways. The management orientations, the focus on the trophies, images of excitement, and the corporate agendas have brought sensitive contradictions to its principles of inclusion.
