Emotions influence motivation, but emotions, such as disgust, have attracted less attention in learning research. We assessed the influence of disgust measured as trait and specific state component, state anxiety and self-efficacy on intrinsic motivation during the dissection of a fish using a pre-/post-design in science teacher students. Anxiety and disgust had a negative influence on motivation. Students with more experience in dissections reported lower pressure. Anxiety after the lesson was influenced by prior anxiety and by animal reminder disgust. Specific state disgust after the dissection was predicted by prior specific state disgust, core disgust and state anxiety. State anxiety and specific state disgust decreased during the dissection. The future commitment to use dissection at school was solely predicted by interest; competence and pressure failed the significance level marginally. 相似文献

ABSTRACTMeasuring teachers’ skills to carry out the complex tasks required in teaching is an important means of evaluating the effectiveness of teacher education but remains a challenging activity to conduct in practice. It is necessary to optimise approaches for usability and effectiveness along a continuum from low-effort and low-authenticity measures such as paper-and-pencil tests to high-effort, high-authenticity measures such as extended classroom observations. The first part of the paper reviews a range of efforts toward measuring the competencies of teachers and other professionals in carrying out the tasks that make up their work. These include performance tests such as computer-based simulations or simulations using actors, as well as the use of tasks requiring participation in or responses to video vignettes. Video vignette approaches typically have been less interactive than performance tests and interactivity is seen as a desirable feature. A novel framework for developing performance-oriented testing is then outlined. The second part of the paper exemplifies this framework in relation to providing explanations in physics classrooms. The development of a novel test instrument following the framework is described, and findings on construct validity are presented to support the applicability of the presented approach. 相似文献

Many societies are encountering significant changes in their population structure as the number of older people is increasing while children and adolescents become fewer. This study examines pupils' attitudes towards elderly people in Germany. A total of 935 pupils (458 boys, 477 girls) participated in this study. Grade distribution was as follows: 192 (5th grade), 148 (6th grade), 208 (7th grade), 219 (8th grade), and 168 (9th grade). We provide evidence for two underlying latent factors, “prejudice” and “appreciation.” The “prejudice” factor contained prejudices and negative attitudes towards old people, and the “appreciation” factor contained items that were positively related to old people. On average, pupils valued old people. Based on a multivariate general linear model, we found a significant influence of gender, grade, and distance to grandparents. Girls valued old people higher, thus rating them higher on the appreciation scale. However, effect size was comparably low. No differences existed concerning the prejudice scale. Grade effects showed that prejudice increases and appreciation declines with increasing age. Distance to their grandparents significantly influenced the attitudes. Pupils with grandparents in the near vicinity valued old people more than pupils with their grandparents farther away. We suggest implementing intergenerational educational programs in primary school and in 5th and 6th grade in Germany. 相似文献

We surveyed interest in ecology prior, during, and after an ecological unit of 14 lessons (“Ecosystem Lake”). Achievement was assessed in a pretest (T-1), a class test (T-2; used for grading), and a retention test (T-3). We found a main effect of stratification on the level of interest in ecology after the educational unit (pupils from the highest stratification were more interested) but not of gender. As expected, the pre-treatment interest scores showed a highly significant influence on the post-treatment scores. Apart from interest prior to the study, situational interest measured during the educational unit also significantly influenced interest after the treatment. Positive correlations between all 3 interest scales and between interest scales and achievement scores were found. Thus, both predisposition and situational interest influence achievement. However, using regression revealed that prior interest had the strongest impact on achievement. 相似文献

In recent years, firms have increasingly contributed to and been confronted with a patent landscape characterized by numerous but marginal inventions, overlapping claims and patent fences. As a result, firms risk their patent applications to be pre-empted or to be infringed upon by rivals. While both aspects constitute major challenges for the appropriation of returns to inventive activity, extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems. In this paper, we investigate the effect of pre-empted and infringed patents on firms’ engagement in in- and cross-licensing. Based on a sample of more than 1100 German manufacturing firms our results show that firms engage in in-licensing as a reaction to pre-empted patents and in cross-licensing if their protected IP was infringed upon. However, these effects vary depending on the fragmentation of technology fields and whether the firm operates in a discrete or complex product industry. 相似文献

We investigated the associations between selected anthropometric and training characteristics with race time in 84 recreational male long-distance inline skaters at the longest inline marathon in Europe, the 'Inline One-eleven' over 111 km in Switzerland, using bi- and multivariate analysis. The mean (s) race time was 264 (41) min. The bivariate analysis showed that age (r = 0.30), body mass (r = 0.42), body mass index (r = 0.35), circumference of upper arm (r = 0.32), circumference of thigh (r = 0.29), circumference of calf (r = 0.38), skin-fold of thigh (r = 0.22), skin-fold of calf (r = 0.27), the sum of skin-folds (r = 0.43), percent body fat (r = 0.45), duration per training unit in inline skating (r = 0.33), and speed during training (r = -0.46) were significantly and positively correlated to race time. Stepwise multiple regression showed that duration per training unit (P = 0.003), age (P = 0.029) and percent body fat (P = 0.016) were the best correlated with race time. Race time in a long-distance inline race such as the 'Inline One-eleven' over 111 km with a mean race time of ~260 min might be predicted by the following equation (r(2) = 0.41): Race time (min) = 114.91 + 0:51* (duration per training unit, min) + 0:85* (age, years) +3:78* (body fat, %) for recreational long-distance inline skaters. 相似文献
