The goal of the present study is to identify prospective special education teachers (SETs) who may have difficulties in coping with occupational stresses and burdens. International comparative studies show that SETs have a higher level of stress than their colleagues who work in the general school system. Compared with teachers in regular schools, SETs leave their profession at a higher rate. For this reason, the study focuses on so-called dysfunctional cognitions, which might increase stress in strenuous occupational situations and which have long-term harmful effects on health. The construct of dysfunctional cognitions is supposed to be a basis for developing supportive measures for teacher students with low stress tolerance. In the framework of the present study located in the German educational system, teacher students (N = 333) from the special needs areas, including learning disability, mental disability, emotional/social disorders and sensory disabilities (hearing impairment, or speech or language disorders), are taken into account. A hierarchical cluster analysis and a discriminant analysis were used to identify four different clusters: Cluster 1 shows the lowest attitude level of equally all dysfunctional cognitions. Clusters 2 and 3 are characterised by higher degrees, especially of ‘dependency’, ‘internalisation of failure’ and ‘personal standards (perfectionism)’. The fourth profile indicates the highest degree of the dysfunctional cognitions. Lower levels of dysfunctional cognitions (with the exception of perfectionism) occur together with a higher expectation of self-efficacy. No cluster applies for all teacher students of one specific special needs area. Prospective teachers in the area of mental disability are overrepresented in cluster 3, with a high level of internalisation of failure and dependency. Teacher students in the area of emotional/social disorders belong, to a considerable degree, to the ‘risk’ cluster. The profiles are used to develop measures for those teacher students who may experience difficulties in stressful occupational situations. Therefore, these student teachers need to be closely supported through additional intensive training elements and balanced career counselling. 相似文献

The aim of this study was to investigate the acute effects of prior exercise (warm‐up and stretching) on the electromyographic and force output of mechanically elicited triceps surae reflexes. Fifty male subjects performed eight reflex experiments under each of three successive conditions in one session: (1) no prior exercise, (2) after static stretching of the passive triceps surae (3 min) and (3) after a 10‐min warm‐up run on a treadmill. Tendon tap reflex force was elicited in the triceps surae of the right leg by means of a standardized reflex hammer and measured in a custom‐built fixture. Electromyographic (EMG) signals were recorded with surface electrodes over the medial head of the gastrocnemius (G) and the soleus (S). Low coefficients of variation within subjects contrasted with high between‐subject variations, indicating highly individual reflex characteristics. After stretching, reductions in the peak force (‐5%; P < 0.05), the force rise rate (‐8%; P < 0.01), the half relaxation rate (‐5%; N.S.), the EMG amplitudes (G, ‐16%; S, ‐17%; P < 0.01) and integrals (G, ‐15%; S, ‐18%; P < 0.01), and an increase in EMG latencies (G, +3%; S, +1%; P < 0.01), were found compared with the values obtained without prior exercise. After running, the peak force reached the values obtained without prior exercise (‐2%; N.S.), the force rise rate and half relaxation rate increased by 8 and 12%, respectively (P < 0.01), and the impulse (force‐time integral; ‐12%), EMG amplitudes (G, ‐20%; S, ‐23%; P < 0.01), integrals (G, ‐18%; S, ‐23%; P < 0.01) and latencies (G, ‐1%; S, ‐2%; P < 0.01) decreased significantly. The changes in the force characteristics observed after the stretching treatment indicate improved muscle compliance that might reduce the risk of injury. On the other hand, the changes after the additional warm‐up run had a more pronounced influence with regard to improved force development and a decreased EMG activity, which can be viewed as a performance‐enhancing effect. 相似文献

In this article the author reviews and discusses John Hattie’s book Visible Learning. In this book Hattie presents the results of a meta‐meta‐analysis on the conditions of successful teaching and learning in schools. Hattie’s work is based on more than 800 meta‐analyses, and these meta‐analyses are substantiated by more than 50 000 empirical research studies. Among the six groups of factors influencing successful learning in schools—student, home, school, teacher, curricula, teaching—the factor ‘teacher’ seems to have the strongest effect. Hattie not only evaluates empirical research but also places the results in a theoretical context of a theory of teaching and a certain concept of teacher professionalism. The author discusses Hattie’s approach to combine empirical research and conceptual work on teaching and on teachers’ work. The limits of meta‐analyses and future meta‐meta‐analyses are pointed out. 相似文献

Orthographies vary in the support they provide for word identification based on grapheme-phoneme correspondences. If skills developed in acquisition of first-language (L1) reading transfer to reading English as a foreign language (EFL), the extent to which EFL readers' word identification shows reliance on information other than grapheme-phoneme correspondences could be expected to vary with whether their L1 orthography is a non-Roman alphabet such as Korean hangul or a nonalphabetic (morpho-syllabic) system such as Chinese characters. Another influence could be whether EFL readers have learned to read a morpho-syllabic L1 by means of an alphabetic transliteration. English text reading speeds and oral reading quality ratings of three groups of adult Asian EFL readers attending an American university were compared with those of two groups of American L1 readers: Graduate student peers and eighth-grade students. All EFL groups read more slowly than both groups of L1 readers, and their reading was more impaired when orthographic cues were disrupted by mixed case print or pseudohomophone spellings. Some of these effects were reduced in EFL readers from Hong Kong, who had earlier exposure to English. Contrary to previous findings, no effects could be attributed to type of first orthography or early exposure to alphabetic transliteration of Chinese characters, which differentiated the Taiwanese and Hong Kong groups. As a whole, the results suggest that, at least across the L1 groups studied, differences in EFL word reading are associated less with type of L1 orthography than with history of exposure to English. 相似文献

At the beginning problems of reconstructing the recent development of empirical educational research are discussed, especially problems resulting from its interdisciplinary character, its divergent institutional contexts and its multimethod approach. The next parts deal with the position of and relation between various disciplines involved in educational research in Germany. Compared to previous times currently important shifts concerning the relation between involved disciplines can be observed. It is a quarrel about responsibility, about the right do define success criteria and about resources. Neither from practical nor theoretical contexts, however, an indisputable Archimedean point can be obtained – where such a point would lie is precisely debatable. 相似文献

Due to a comparatively weak curricular structure in education faculties, student teachers may determine their study experiences and learning processes largely by themselves, by selecting their own priorities within educational foundation studies. This paper focused on the relationship between individually-chosen educational specializations, self-perceived competence in these chosen fields, and the measured educational knowledge. The study among teacher education graduates in the German state North Rhine-Westphalia showed that the individually chosen priorities within educational courses varied greatly; however, a focus on topics like classroom teaching, learning and development, and creating school environments was discernable. Results revealed that graduates with certain courses of specializations showed a significant higher level of knowledge in self-report in according areas. However, there were only small significant correlations between the self-reported competencies and the educational knowledge measured by the test. The results of the standardized test of educational knowledge indicated that the graduates in fact achieved better test results in their prioritized fields of studies. This suggests that individual course selection in educational foundations does have an effect on subsequent educational knowledge. 相似文献
