The New Zealand Qualifications Authority takes the credit for education

Education in many Western countries is being reformed. The paper examines the role of the New Zealand Qualifications Authority in the neo-liberal reforms and their revenue gathering from students credits in a contradictory neo-liberal policy context.     

School Governors: An LEA Perspective

The article relates the experiences of one large comprehensive school in its first year as a member of a pilot Local Resource Management (LRM) scheme. It considers some of the difficulties, the training implications and some of the advantages and disadvantages which have already come to light. Some advice is also given to other schools which are likely to be involved in such schemes as soon as the ‘Baker Bill’ becomes law.     

Does extensive on-water rowing increase muscular strength and endurance?

The purpose of this study was to compare changes in aerobic condition, strength, and muscular endurance following 8 weeks of endurance rowing alone or in combination with weight-training. Twenty-two elite rowers were assigned to (1) rowing (n = 10, 250-270 km · week?1) or (2) rowing (n = 12, 190-210 km · week?1) plus four weight-training sessions each week. Pre and post mean and standardized effect-size (ES) differences in aerobic condition (watts at 4 mmol · L?1) and strength (isometric pull, N), prone bench-pull (6-repetition maximum, 6-RM), 5- and 30-repetition leg-press and 60-repetition seated-arm-pull (J, performed on a dynamometer) normalized by body mass and log-transformed were analysed, after adjusting for gender. The standardized differences between groups were trivial for aerobic condition (ES [±90% CI] = 0.15; ±0.28, P = 0.37) and prone bench-pull (ES = 0.27; ±0.33, P = 0.18), although a moderate positive benefit in favour of rowing only was observed for the seated-arm-pull (ES = 0.42; ±0.4, P = 0.08). Only the weight-training group improved isometric pull (12.4 ± 8.9%, P < 0.01), 5-repetition (4.0 ± 5.7%, P < 0.01) and 30-repetition (2.4 ± 5.4%, P < 0.01) leg-press. In conclusion, while gains in aerobic condition and upper-body strength were comparable to extensive endurance rowing, weight-training led to moderately greater lower-body muscular-endurance and strength gains.     

Anthropometry, strength and benchmarks for development: a basis for junior rowers' selection?

The aims of this study were to establish whether anthropometry, muscle strength and endurance accounted for differences between junior and senior elite rowing ergometer performance, and to determine annual development rates for juniors associated with training. Twenty-six junior (8 females, age 18.0 ± 0.3 years and 18 males, age 17.9 ± 0.2 years) and 30 senior (12 females, 23.7 ± 3.0 years and 18 males, 24.0 ± 3.9 years) heavyweight rowers, were assessed anthropometrically, performed a 2000-m ergometer time-trial, and completed various muscular strength and endurance tests. There were no anthropometrical differences between males; however after controlling for body-fat and standing-height, senior females were of greater body-mass (70.5 ± 4.6 kg and 77.2 ± 5.9 kg, P = 0.01) and sitting-height (89.8 ± 2.2 cm and 92.2 ± 6.1 cm, P = 0.04) than juniors. Moderate to very large standardised differences in all strength and endurance tests were observed between juniors and seniors (effect size (ES) range 0.9-1.9). Greater development rates (5.0% to 6.0%) and adjusted 2000-m performance was associated with upper-body strength (males) and endurance (females). In conclusion, after identification of desirable anthropometry, the 2000-m ergometer potential of juniors may be accounted for by upper-body strength and endurance.     

The development,validation, and potential uses of the Student Interest-in-the-Arts Questionnaire

The Student Interest-in-the-Arts Questionnaire was designed to measure elementary school students’ interest in dance, drama, music, and the visual arts. We collected data providing evidence for reliability, content validity, construct validity, and convergent and discriminant validity. We describe the development of the method and the collection and analysis of the validity data. The brief instrument is easy to administer, fills a gap in the compendium of available instruments, and is useful in a variety of settings with a variety of research and evaluation designs.
