The present study examined whether stress in professional caregivers – as reflected in salivary cortisol levels – is related to the quality of their caregiving behavior. The 221 professional female caregivers in 64 child care centers were observed in three different situations and saliva samples were taken three times during the morning. Results showed that higher levels of cortisol, particularly at the beginning of the workday, predicted lower-quality caregiver behavior beyond the contribution of three other predictors, namely a higher self-reported physical workload, more children under age two in the care group, and lower caregiver age. Contrary to the expectation, higher cortisol levels did not mediate the relation between higher self-reported physical workload and more children under age two on the one hand and lower-quality caregiving behavior on the other.  相似文献

Abstract

Nine- to 10-year-old children have difficulty playing baseball using adult rules because pitchers lack the ability to throw the ball over the plate with consistency and batters lack ability to hit erratically thrown balls. Thus a natural field experiment investigated a modification of adult baseball for 9- to 10-year-old children. Instead of one of the players on the opposing team pitching, the coach of the offensive team pitched to the batters. Teams in a league who played baseball by adult rules (traditional league) were compared with teams in a league who played the modified game (nontraditional league), and both these leagues were compared with 11- to 12-year-old teams (older league). Various offensive and defensive activities were recorded by two observers and satisfaction scores were obtained from the players after the games. More offensive and defensive activity occurred in the nontraditional league games than in the traditional and older league games.  相似文献

In this study, we examined the development of mathematics achievement in children attending extracurricular activities intensively in comparison with the development in a control group of children attending only the obligatory hours of school instruction. In addition, we investigated the question of possible effects of intensity of attendance and quality of extracurricular activities on achievement in students attending extracurricular activities from the end of Grade 1 to the end of Grade 3. This was a longitudinal study of a sample of N = 295 students in the first years of school at 35 primary schools in the German-speaking part of Switzerland. The results show that attendance in extracurricular activities had a positive effect on the development of students’ achievement. Students who attended extracurricular activities intensively in Grade 1, students who attended high-quality extracurricular activities, and especially those who did both, had greater improvement.  相似文献

There is a crisis in school science in Australia and this may be related to insufficient students developing an interest in science. This extended study looked at changes in 14 students’ interest in science as they moved through junior secondary school into Year 10. Although the majority of these students still had an interest in science in Year 10, it had fluctuated for most students from year to year. The presence or absence of simple, but effective, teaching practices, identified by these students, seems to suggest one way to retain or improve situational and, it would appear, in several cases, personal interest.  相似文献

Research pertaining to science museum exhibit design tends to be articulated at a level of generality that makes it difficult to apply in practice. To address this issue, the present study used a design‐based research approach to understand the educational potential of a biology exhibit. The exhibit was considered an educational environment which embodied a certain body of biological knowledge (Biological Organisation) in a certain exhibit type (Museographic Organisation) with the intention of creating certain learning outcomes among visitors. The notion of praxeology was used to model intended and observed visitor outcomes, and the pattern of relationship between the two praxeologies was examined to pinpoint where and how divergences emerged. The implications of these divergences are discussed at the three levels of exhibit enactment, design, and conjecture, and theoretically based suggestions for a design iteration are given. The potential of the design‐based research approach for educational exhibit design is argued.  相似文献

One of the results of a lack of overall co‐ordination of adult education in Australia is a very incomplete record of activities. Attempting to use existing data for research can be a very frustrating business. The form of the material available varies from State to State, is incomplete and uneven in quality. The peripheral nature of adult education in relation to education as a whole often results in only brief mention in official reports or no comment at all. The voluntary area, due for the most part to the spontaneous and informal nature of many agencies, is particularly poorly recorded. This paper discusses some of the problems facing researchers and brings together existing studies which have attempted to survey arrangements for the organisation and administration of adult education on a national basis.  相似文献

Abstract

If farmers are to meet the new challenges facing agriculture (environment, rural development, etc.), appropriate knowledge has to be produced. But observations in six EU countries (France, Germany, Greece, the Netherlands, Spain and the UK) show that unexpected problems arise when technical support for agriculture is linked to market regulation, as recommended since the late 1980s. The source of these problems can be understood better by applying concepts from the service economy: i) The production of new knowledge requires strong interaction between service providers (technical support bodies) and beneficiaries (farmers). The weakening of non-market regulation procedures, which partly guaranteed these possibilities of interaction, makes the conception of an advisory service difficult. ii) As soon as consultancy becomes a paying service, some beneficiaries reduce technical interaction with their colleagues in order to benefit from a productive advantage, and the ‘multipliable’ nature of new knowledge is reduced. iii) An increasing number of farmers are excluded from the benefits of technical support even though they help to provide services that society expects from agriculture (management of the land, maintenance of activities in low-density areas). iv) The responsibility for combining contradictory requirements (competitiveness, environment, rural development) is most often put on the shoulders of individual farmers who are unequipped to deal with such complex issues. Observed trends attest to the fact that effects often run counter to the stated agricultural and rural development objectives of policies.  相似文献

Various research findings, mostly from Anglo-American countries, evidence the medical profession to be strongly familial and further suggest that a medical family background may be associated with study success in medical undergraduates. This study explored the familial aggregation of the medical profession among 1-year cohort samples of medical and psychology students in Austria. Whereas physicians only amount to about 0.4% of the total Austrian population, 45.8% of final-year medical students reported any and 25.6% a first-degree medical relative. Male students more likely had physicians in their family than female students and both sexes more likely had male than female medical relatives. Male final-year medical students with first-degree medical relatives were significantly younger than those without, thus indicating faster study progress in this group. Physicians also ran in the families of psychology students, as did psychologists and psychotherapists. Implications of these findings, study limitations, and avenues for future research are discussed.  相似文献

This study set out to explore motor competence in 4-year-old children. This age group has not been previously tested in Norway. Ninety-one 4-year-old children from ten nursery schools were tested using the Movement ABC test. The most striking finding was that only one out of 91 children would be classified as clumsy within the fifth percentile of the USA norms, with seven children being 'borderline'. The study also showed that out of the eight children failing in the motor impaired and borderline groups, seven were boys. Clear sex differences were also apparent in the development of motor skills. On the total scores and in the two of three sections (manual dexterity and balance) boys were significantly worse than girls. There were no significant differences between the sexes with respect to ball skills competence.  相似文献
