Teacher educators’ processes of establishing “mathematics for teaching” in teacher education programs have been recognized as an important area for further research. In this study, we examine how two teacher educators establish and make explicit features of mathematics for teaching within classroom interactions. The study shows how the establishment of mathematics for teaching is dependent on the use of keywords from the mathematics education domain, the introduction of variation, and the use of generic communicative strategies. As such, the study could be seen as a contribution to ongoing research on how mathematics teacher educators interactively deal with mathematics for teaching. 相似文献

This study identifies and analyses professional norms as a means of illuminating school cultures and how norms are distributed in the system. Of special interest is the role of school leaders and how they lead, organize and realise school development. The study research question is: What professional norms do school leaders highlight in change efforts? We are also interested in identifying the support mechanisms and obstacles to implementation and norm setting exhibited by school organisations. The case we used explores change processes in the implementation of education for sustainable development at three upper secondary schools in Sweden. It was conducted in three phases, starting with a questionnaire for all teachers and principals. In the second phase, each of the principals was interviewed individually. The third phase used focus groups consisting of the principals that made up the leadership groups. Our results indicate that professional norms are set when principals and teachers experience expectations from each other, from students and from policy documents. There is also a need for well-functioning communication in the organisation to set and disseminate norms. The school principal plays a crucial role in these norm setting processes. By becoming more aware of existing norms in the organisations, and how norms can be changed, this knowledge can support principals in change efforts. 相似文献

In 2014, a newly formed group of teachers graduated from Swedish universities. In addition to their qualification as leisure-time pedagogues, their degree includes teaching practical/aesthetical subjects in compulsory school. This group of teachers thus has to relate to dual professional identities and to maintain a balance between the socially oriented leisure-time centres and a goal- and results-driven school. In this article we describe their first two years after graduation, trying to get hold of their negotiation of professional identities and orientation in the professional landscape. Results shows that the graduates try to balance own ideals and hybrid professional intentions against traditional professional identities and labour market conditions and that position in a liminal phase might be crucial for the outcome. 相似文献

Rand, G. & Rand, P. The Effects of Working Atmospheres on Creativity. Scandinavian Journal of Educational Research 22, 91‐106. Previous studies on effects of variations in working atmosphere upon creativity have shown confusing results. Part of an explanation of this confusion may be found in this report. Data were gathered from 588 sixth grade Oslo children (301 boys, 287 girls). Half of the Ss worked on two originality tests under relaxed and the other half under stressful working conditions. There is a clear difference between the distributions of creativity scores in the two atmosphere groups. The percentages of very low and very high scores are lower in the stressful than in the relaxed group. This difference is found regardless of sex, intelligence or test anxiety of the Ss. If this difference in percentages indicates that two counteracting tendencies are at work simultaneously, when we shift from one type of working atmosphere to the other, mean scores may not be well suited for the presentation of data pertaining to the effects of working conditions. As previous studies often have relied on mean values in data presentation, this may, at least partly, account for the confusing results. 相似文献

Rand, P. 1978. Some Validation Data for the Achievement Motives Scale (AMS). Scandinavian Journal of Educational Research 22, 155‐171. The AM Swas administered to 588 sixth grade Oslo children, 301 boys and 287 girls. Among other tests given were 6 verbal and 2 numerical tests, TASC, and a Lie/Defensiveness Scale. On the basis of achievement theory, scores on the AMS subscale for motive to seek success (M5) were predicted to be positively related to performance on the verbal and numerical tests, and scores on the subscale for motive to avoid failure (Mf) to be negatively related to those scores. The theory also leads to the assumption that the difference in performance between individuals high and low in motive scores would be clearest on tasks experienced as being of medium difficulty. The results show predicted and mostly significant relationships. Even when related to the tests of personality characteristics, the AMS shows promising qualities. TASC scores are related positively to Mf scores and negatively to Ms scores. The fact that AMS scores show negligible correlations with lie/defensiveness scores indicates that the risk of faked AMS scores may be small. 相似文献

In this study, we present longitudinal data on changes in psychological distress among 232 Norwegian undergraduate students of nursing, physiotherapy, and occupational therapy. Psychological distress was assessed by applying the 12‐item version of the General Health Questionnaire. Nursing students became substantially more distressed during the three years of their programme compared to physiotherapy and occupational therapy students. Multivariate analyses showed that the students’ levels of psychological distress at the beginning of the study was the most important predictor of psychological distress at the end of the study. Other significant predictors were qualities of the individual student’s personal life, clarity in educational structure, subjective experience of study workload, and level of support in student milieu. 相似文献

This article reviews ten predictive validity studies of the Swedish Scholastic Assessment Test (SweSAT). A primary result is that the predictive validity of the SweSAT seems to be highly dependent upon the study programme being examined; that is, the predictive validity is better at some programmes than others. When compared with the upper‐secondary school grade point average, the predictive validity of the SweSAT seems to be fairly good, but there are major differences between study programmes in this case as well. However, it is suggested that the validity of the results is to some extent threatened by methodological issues. A general conclusion is, therefore, that there is room for improving the test itself, as well as the way that predictive validity studies are carried out. 相似文献

In recent decades, the basic principle in Norway’s education policy has been that all students should receive adapted education within the framework of the mainstream schools. This policy notwithstanding, the rate of students for whom special support was initiated, rose from 6.2% in 2006 to 8.0% in 2014. The study reported here developed measures for the possible causes for this unwelcome development. A questionnaire with 23 statements suggesting possible causes of the increase in the use of special support was presented to 136 teachers in primary and lower secondary school. A factor analysis revealed that 12 items formed three reliable scales for possible causes behind the high demand for special provisions: ‘Focus on students’ problems’, ‘External pressure on schools’ and ‘Early support’. The teachers stated that these causes had moderate impact. The study has resulted in three scales useful in measuring three causes. 相似文献

AbstractHip adduction strength is important for kicking and acceleration in soccer players. Changes in hip adduction strength may therefore have an effect on soccer players’ athletic performance. The purpose of this study was to investigate the acute and sub-acute effects of a kicking drill session on hip strength, concerning isometric hip adduction, abduction and flexion torque of the kicking leg and the supporting leg. Ten injury-free male elite soccer players, mean ± s age of 15.8 ± 0.4 years participated. All players underwent a specific 20 min kicking drill session, comprising 45 kicks. The players were tested the day before, 15 min after and 24 h after the kicking drill session by a blinded tester using a reliable test procedure. The isometric hip-action and leg-order were randomized. For the kicking leg, hip adduction torque increased from 2.45 (2.19–2.65) Nm ? kg?1, median (25th–75th percentiles), at pre-kicking to 2.65 (2.55–2.81) Nm ? kg?1 (P = 0.024) 24 h post-kicking. This may have implications for the soccer player’s ability to maximally activate the hip adductors during kicking and acceleration, and thereby improve performance the day after a kicking drill session. 相似文献

Abstract Maximal oxygen uptake ([Vdot]O2max) is considered the optimal method to assess aerobic fitness. The measurement of [Vdot]O2max, however, requires special equipment and training. Maximal exercise testing with determination of maximal power output offers a more simple approach. This study explores the relationship between [Vdot]O2max and maximal power output in 247 children (139 boys and 108 girls) aged 7.9–11.1 years. Maximal oxygen uptake was measured by indirect calorimetry during a maximal ergometer exercise test with an initial workload of 30 W and 15 W · min?1 increments. Maximal power output was also measured. A sample (n = 124) was used to calculate reference equations, which were then validated using another sample (n = 123). The linear reference equation for both sexes combined was: [Vdot]O2max (ml · min?1) = 96 + 10.6 · maximal power + 3.5 · body mass. Using this reference equation, estimated [Vdot]O2max per unit of body mass (ml · min?1 · kg?1) calculated from maximal power correlated closely with the direct measurement of [Vdot]O2max (r = 0.91, P <0.001). Bland-Altman analysis gave a mean limits of agreement of 0.2±2.9 (ml · min?1 · kg?1) (1 s). Our results suggest that maximal power output serves as a good surrogate measurement for [Vdot]O2max in population studies of children aged 8–11 years. 相似文献
