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

The aims of the EVINCE research projectincluded examination of the impact of information on the clinical knowledge and practice ofnurses, midwives and health visitors. EVINCE (Establishing the Value of Information to NursingContinuing Education) was funded by the British Library R&D Department for 1 year, from 1November 1995 to 31 October 1996. The methods employed (based on those used in the Valueproject) included a critical incident type study to establish patterns of information need and useamong a random sample of nursing professionals. The nature of the impact of informationobtained on present and future competencies was assessed from a survey of the searches andrequests presented to library and information services. Nurses, midwives and health visitors didvalue the information (96% of respondents agreed that there was, or would be an effect onfuture practice through enhanced competence in one or more areas). The impact findings can beused to guide a more precise assessment of information needs.  相似文献

In Ireland and the UK it is accepted practice that agencies with formal responsibility for delivering school examinations allow examination candidates, and in many cases their teachers, to see their examination papers once they have been marked. Returned papers can carry various pieces of information; as well as the total score given for a performance, additional information is included in the form of the annotations left on the examination paper by the marking examiner. As far as we know there has been no research into how this information affects those who come into contact with it. The study uses teacher interview and survey data to explore whether a sociocultural approach to analysis can illuminate the factors that might influence their interpretation of those annotations. These analyses suggest that a key influence on the valid interpretation of an examiner's annotations is a teachers' involvement in examining activity. The analyses support further conceptualisation that these teacher-examiners' interpretative capacity is related to their positioning in a boundary zone between two different activity systems.  相似文献

A high ambient temperature reduces the capacity to perform prolonged exercise. Total carbohydrate oxidation is less, and thus glycogen depletion is not limiting. Fluid ingestion in the heat should, therefore, focus on maintenance of hydration status rather than on substrate provision. Six healthy males cycled to exhaustion at 60% of maximum oxygen consumption (VO 2max ) with no drink, ingestion of a 15% carbohydrate-electrolyte drink (1.45 - 0.29 litres) or ingestion of a 2% carbohydrate-electrolyte drink (3.12 - 0.47 litres). The ambient temperature was 30.2 - 0.6°C (mean - s ), with a relative humidity of 71 - 1% and an air speed of approximately 0.7 m.s -1 on all trials. Weighted mean skin temperature, rectal temperature and heart rate were recorded and venous samples drawn for determination of plasma volume changes, blood metabolites, serum electrolytes and osmolality. Expired gas was collected to estimate rates of fuel oxidation. Exercise capacity was significantly ( P ? 0.05) different in all trials. The median (range) time to exhaustion was 70.9 min (39.4-97.4 min) in the no-drink trial, 84.0 min (62.7-145 min) in the 15% carbohydrate trial and 118 min (82.6-168 min) in the 2% carbohydrate trial. The 15% carbohydrate drink resulted in significantly ( P ? 0.05) elevated blood glucose and total carbohydrate oxidation compared with the no-drink trial. The 2% carbohydrate drink restored plasma volume to pre-exercise values by the end of exercise. No differences were observed in other thermoregulatory or cardiorespiratory responses between trials. These results suggest that fluid replacement with a large volume of a dilute carbohydrate drink is beneficial during exercise in the heat, but the precise mechanisms for the improved exercise capacity are unclear.  相似文献

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

The purpose of this study was to determine the differences between third and sixth grade female and male students when retelling orally a story read silently. The students' retelling of the story was analyzed by comparing how closely, both structurally and linguistically, they paralleled the T-units or communication units of the author. In general, female students performed significantly differently than did male students. The researchers examine these differences in light of recent research in the area of gender differences.  相似文献

Changes to special educational needs and disability (SEND) legislation in England were implemented in 2014. Here, we evaluate the impact of these changes from the perspective of 80 autistic young people aged 16–25 years. Using an online survey and/or interviews, we examined young people’s views on three key principles of the SEND reforms: the help and support provided to them; whether they were given a say in the choices and support that they were offered; and their satisfaction with their educational journeys and outcomes. The results paint a mixed picture. Our sample of young people reported varied experiences regarding the help and support they received, and how much of a say they had regarding the choices and support available to them. The types of schooling they accessed played a role here: young people in mainstream schools highlighted particular challenges in accessing appropriate support, while many young people in special schools said they felt well supported. Parental advocacy was crucial for all young people, as was having key ‘champions’ in the form of teachers who really knew them well. The need for the development of general life and self-advocacy skills was apparent, however, especially in preparing the young people for life after school. Encouragingly, most of our participants were generally happy with their current situation, despite identifying several areas for further improvement. Overall, the results highlight the importance of listening to—and learning from—autistic young people, throughout their educational journeys and especially as they transition to adulthood.  相似文献
