Pupil Speech during Morning News: the effects of reducing teacher questions and increasing pauses and praise     

Dennis W. Moore  Tony Knott  Stuart McNaughton 《教育心理学》1989,9(4):311-320

Classroom discourse patterns were examined in the morning news sessions of a primary school classroom. The effects of reducing teacher questions and increasing rates of teacher pauses, praise and directives were investigated. Child words spoken and child expansions were recorded, as well as class call‐outs and teacher control statements. Frequencies of child words spoken showed no significant changes across the phases of the study. However, reducing teacher questions and increasing teacher pauses significantly decreased child expansions, while reducing teacher questions and increasing teacher praise significantly increased child expansions. Replacing teacher questions with directives had no significant effect upon child expansions. Class call‐outs and teacher control statements showed no significant changes across the intervention phases. The results of this study suggest that, for this teacher and class, teacher questions may be decreased without adversely affecting either child utterances or class behaviour, and that replacing questions with praise may increase children's contributions — particularly in the form of verbal expansions — to morning news talks.  相似文献   

Phosphate loading and the effects on VO2max in trained cyclists     

I Stewart  L McNaughton  P Davies  S Tristram 《Research quarterly for exercise and sport》1990,61(1):80-84

It is known that an increased level of red blood cell 2,3-diphosphoglycerate (DPG) shifts the oxyhemoglobin dissociation curve to the right, thus allowing a greater unloading of oxygen at the tissue level. It has been hypothesized that phosphate might help increase VO2max by increasing 2,3-DPG level. Eight trained cyclists underwent three cycle ergometer tests (control, placebo, and experimental) to determine whether phosphate ingestion had any positive effect on VO2max, time to exhaustion, serum 2,3-DPG, and serum phosphate levels. We found no change between the control, placebo, or experimental conditions in pretest serum phosphate levels, but we did find increases in 2,3-DPG levels in the phosphate condition (p less than .05), which suggests that even a small amount of phosphate could increase levels of 2,3-DPG. We also found significant differences in VO2max between the control (p less than .05) and placebo (p less than .02) conditions and also in time to exhaustion between the three conditions (p less than .05). We suggest that phosphate may have an ergogenic effect, but clearly more work needs to be undertaken to ascertain the amount of phosphate required and the magnitude of the effect.  相似文献   

Reading the mass violence in Indonesia 1965–1966 as a form of primitive accumulation     

Colm McNaughton 《Inter-Asia Cultural Studies》2013,14(2):292-305

Abstract

A human rights perspective is compromised in its ability to understand and respond to the mass violence that took place in Indonesia, largely against members and supporters of the Indonesian Communist Party (PKI) from 1965–1966. In “Indonesia's Original Sin: Mass Killings and Capitalist Expansion, 1965–66,” Hilmar Farid makes the point that a human rights standpoint is limited when capital or its various actors, are involved in propagating and/or perpetrating mass violence. In starting to fashion an alternative reading, Farid proposes Marx's notion of primitive accumulation. While Farid's position is suggestive, I contend that his analysis is marred by a number of theoretical weaknesses, which I attempt to sublate in this article. As such, I will offer an alternative reading of primitive accumulation perceived through a multi-dimensional local/global dialectic.  相似文献   

The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia     

Georgina L. Kent  Brian Dawson  Lars R. McNaughton  Gregory R. Cox  Louise M. Burke  Peter Peeling 《Journal of sports sciences》2019,37(3):339-346

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.  相似文献   

A History of Errors in the Analysis of Oral Reading Behaviour     

Stuart McNaughton 《教育心理学》1988,8(1-2):21-30

Abstract Behavioural analyses of oral reading behaviour have ascribed different functions to errors and the correction of errors. Two positions are discussed. One is the legacy of Skinner which views errors as problematic and which advocates near error‐less learning. The other position views errors and potential errors as providing opportunities for self regulation and enhanced feedback. On the basis of recent research this paper argues that errors can have generative and inhibiting effects on oral reading, depending on the instructional context and the literacy goals of the classroom.  相似文献   

From preschool to home: processes of generalisation in language acquisition from an indigenous language recovery programme     

Arapera Royal Tangaere  Stuart McNaughton 《International Journal of Early Years Education》2003,2(1):23-40

Processes of generalising bilingual expertise from Te Kohanga Reo (an indigenous preschool for the revitalisation of Maori language) to home are analysed. Observations at the preschool and home settings revealed several features. The active and strategic role of the child in transferring expertise was evident. So too were the presence of complementary activities at home, sensitive responding to generalised language and shared cultural commitments. These processes were present in a range of activities. The results are discussed in terms of theoretical approaches to generalisation and the effectiveness of indigenous language intervention programmes.  相似文献   

Curriculum as an instrument of change with particular reference to the social sciences     

A. H. McNaughton 《Interchange》1970,1(4):61-69

The social science curriculum of the future must prepare students to face rapidly changing circumstances in their world. The home and church seem to be unable to deal with those changes that are leading to a deterioration in human relationships and moral standards. The school seems to have the greatest potential for meeting the challenge and it is argued here that the most suitable setting in the school is the classroom with a wide range of ability and racial groups in it. The methodological principles stemming from the Taba Curriculum in Social Studies, supplemented and refined by those of Piaget and Kohlberg, offer possibilities for effecting positive social changes to meet the moral crisis at present facing Western society.

Résumé Dans le futur, le programme d'études des sciences sociales devra préparer les élèves à faire face aux changements rapides de leur monde. La maison et l'église semblent incapables de s'occuper des transformations qui mènent à la déterioration des relations humaines et des valeurs morales. Il semble que l'école a le plus grand potentiel pour faire face à ce défi et l'auteur soutient que le meilleur milieu dans l'école c'est la salle de classe composée d'élèves qui ont des aptitudes variées et qui viennent de différents groupes raciaux. Les principles méthodologiques qui dérivent du programme scolaire dans les ciences sociales de Taba, augmenté de ceux de Piaget et Kohlberg, offrent des possibilités d'effectuer des changements sociaux positifs afin de faire face à la crise morale qui confronte à présent la société occidentale.

The effects of sodium bicarbonate ingestion on cycling performance and acid base balance recovery in acute normobaric hypoxia     

Lewis A. Gough  Sanjoy K. Deb  Danny Brown  S. Andy Sparks  Lars R. McNaughton 《Journal of sports sciences》2019,37(13):1464-1471

This study investigated the effects of two separate doses of sodium bicarbonate (NaHCO₃) on 4 km time trial (TT) cycling performance and post-exercise acid base balance recovery in hypoxia. Fourteen club-level cyclists completed four cycling TT’s, followed by a 40 min passive recovery in normobaric hypoxic conditions (FiO₂ = 14.5%) following one of either: two doses of NaHCO₃ (0.2 g.kg^?1 BM; SBC2, or 0.3 g.kg^?1 BM; SBC3), a taste-matched placebo (0.07 g.kg^?1 BM sodium chloride; PLA), or a control trial in a double-blind, randomized, repeated-measures and crossover design study. Compared to PLA, TT performance was improved following SBC2 (p = 0.04, g = 0.16, very likely beneficial), but was improved to a greater extent following SBC3 (p = 0.01, g = 0.24, very likely beneficial). Furthermore, a likely benefit of ingesting SBC3 over SBC2 was observed (p = 0.13, g = 0.10), although there was a large inter-individual variation. Both SBC treatments achieved full recovery within 40 min, which was not observed in either PLA or CON following the TT. In conclusion, NaHCO₃ improves 4 km TT performance and acid base balance recovery in acute moderate hypoxic conditions, however the optimal dose warrants an individual approach.  相似文献

Effects of sodium phosphate and caffeine loading on repeated-sprint ability     

Christopher Buck  Kym Guelfi  Brian Dawson  Lars McNaughton  Karen Wallman 《Journal of sports sciences》2015,33(19):1971-1979

The effects of sodium phosphate and caffeine supplementation were assessed on repeated-sprint ability. Using a randomised, double-blind, Latin-square design, 12 female, team-sport players participated in four trials: (1) sodium phosphate and caffeine, (2) sodium phosphate and placebo (for caffeine), (3) caffeine and placebo (for sodium phosphate) and (4) placebo (for sodium phosphate and caffeine), with ~21 days separating each trial. After each trial, participants performed a simulated team-game circuit (4 × 15 min quarters) with 6 × 20-m repeated-sprints performed once before (Set 1), at half-time (Set 2), and after end (Set 3). Total sprint times were faster after sodium phosphate and caffeine supplementation compared with placebo (Set 1: P = 0.003; Set 2: d = ?0.51; Set 3: P < 0.001; overall: P = 0.020), caffeine (Set 3: P = 0.004; overall: P = 0.033) and sodium phosphate (Set 3: d = ?0.67). Furthermore, total sprint times were faster after sodium phosphate supplementation compared with placebo (Set 1: d = ?0.52; Set 3: d = ?0.58). Best sprint results were faster after sodium phosphate and caffeine supplementation compared with placebo (Set 3: P = 0.007, d = ?0.90) and caffeine (Set 3: P = 0.024, d = ?0.73). Best sprint times were also faster after sodium phosphate supplementation compared with placebo (d = ?0.54 to ?0.61 for all sets). Sodium phosphate and combined sodium phosphate and caffeine loading improved repeated-sprint ability.  相似文献
