The relations of stress and coping over time were investigated among mothers of children (N=36) with mild neurological disabilities and mothers of matched non-disabled (ND) children (N=36). Separate stress groups were formed with respect to changes in adaptational outcomes for the mothers of disabled and ND children. Mothers of disabled children with better adaptational outcomes had considered their self-esteem higher and used problem-focused coping and social support more often than mothers of disabled children with worse adaptational outcomes. Decrease of negative affects seemed to presuppose use of problem-focused coping more often mothers of disabled children than for those of ND children.  相似文献

The present European higher education policy and research policy can be characterized as emphasizing external financing of universities, competition between and within universities, and the need for a more practical and economically profitable output from research and education. A theoretical framework of analysing the impacts of this new rationale can be constructed on the following two premises. First, the funding structure of universities and university research is a main factor that influences the situations in which universities and their members make their decisions on teaching, research and administering. Second, universities consist of various groups of personnel each having and developing objectives and preferences of their own. This theoretical framework is applied to the Finnish science university system. On the basis of the analysis it can be seen that although the new policy probably has clarified the division of labour between universities, there have emerged some negative unintended consequences of the new funding structure. Indications of weakening performance in research and education can be identified in the empirical analysis.

The ability to purposefully access, reflect, and use evidence from educational research (Educational Research Literacy) is expected of future professionals in educational practice. Based on the presented conceptual framework, a test instrument was developed to assess the different competency aspects: Information Literacy, Statistical Literacy, and Evidence-based Reasoning. This paper addresses the question of whether this test allows monitoring students’ development during courses on research methods in educational science. In winter semester 2013/14, two courses in Early Education and Teacher Training degree programs were accompanied. Both cross-sectional (multidimensional latent regression models) and longitudinal (paired t tests of plausible values) comparisons are reported. The results indicate no significant differences in competencies between the degree programs at start of the semester. For the end of semester, only data of the Early Education course was available. These course participants showed higher proficiency in all aspects of educational research literacy. In conclusion, the results are discussed with regard to the goals of the assessment of competencies in higher education, particularly the use of test feedback for course development, and desiderata for future research (e.g., ability to transfer research into practice) are stated.  相似文献

This study analyses the effects which repeating a class has on ninth grade students’ development of mathematical competency. The following research questions were addressed: How many students repeat grades in the different types of schools? How do students who repeat a grade differ from those who do not in their performance and background characteristics? How much extra mathematics do students repeating a grade learn in one school year? What are the differences between various types of school? Can students with poor mathematics grades in particular profit from repeating a grade? The sample is a sub-sample of the PISA-I-Plus study and comprises N = 360 ninth grade students. The total sample of PISA-I-Plus is representative for all ninth/tenth grade students from the different school types in Germany. The data survey was carried out in the ninth grade and then repeated after the students had repeated a year. The results document differences in the amount of grade repeat quotas between types of school. Furthermore, compared to students not repeating, those repeating a grade had lower mathematics (d = 1.02) and german (d = 1.14) grades, a lower level of mathematical literacy (d = 0.51), and lower test results with regard to basic cognitive abilities (d = 0.32). In terms of the development of mathematical literacy, the students repeating a grade could improve by an average of 23 points (d = 0.27) on the PISA mathematics scale. However, the results identify 38 percent of students repeating a grade who do not make any significant improvement in mathematics or even get worse. A differentiation according to school types shows that students repeating a grade in integrated comprehensive secondary schools and in schools with several educational levels in particular do not, on average, show any noteworthy improvement in their mathematical literacy. The analysis of the school grades received in mathematics shows that students whose mathematics grades are unsatisfactory do not benefit more from repeating a grade than students whose mathematics performance has been rated as being “satisfactory” or better. The article concludes with a discussion of the possible consequences of changing the way in which repetitions of grades are dealt with.  相似文献

Protein synthesis and semisynthesis offer immense promise for life sciences and have impacted pharmaceutical innovation. The absence of a generally applicable method for traceless peptide conjugation with a flexible choice of junction sites remains a bottleneck for accessing many important synthetic targets, however. Here we introduce the PALME (protein activation and ligation with multiple enzymes) platform designed for sequence-unconstrained synthesis and modification of biomacromolecules. The upstream activating modules accept and process easily accessible synthetic peptides and recombinant proteins, avoiding the challenges associated with preparation and manipulation of activated peptide substrates. Cooperatively, the downstream coupling module provides comprehensive solutions for sequential peptide condensation, cyclization and protein N/C-terminal or internal functionalization. The practical utility of this methodology is demonstrated by synthesizing a series of bioactive targets ranging from pharmaceutical ingredients to synthetically challenging proteins. The modular PALME platform exhibits unprecedentedly broad accessibility for traceless protein synthesis and functionalization, and holds enormous potential to extend the scope of protein chemistry and synthetic biology.  相似文献

Structural equation models are increasingly used for clustered or multilevel data in cases where mixed regression is too inflexible. However, when there are many levels of nesting, these models can become difficult to estimate. We introduce a novel evaluation strategy, Rampart, that applies an orthogonal rotation to the parts of a model that conform to commonly met requirements. This rotation dramatically simplifies fit evaluation in a way that becomes more potent as the size of the data set increases. We validate and evaluate the implementation using a 3-level latent regression simulation study. Then we analyze data from a statewide child behavioral health measure administered by the Oklahoma Department of Human Services. We demonstrate the efficiency of Rampart compared to other similar software using a latent factor model with a 5-level decomposition of latent variance. Rampart is implemented in OpenMx, a free and open source software package.  相似文献

Several instructional strategies have been recommended for use in heterogeneous classrooms, but the frequency of their actual use has remained largely unknown. Therefore, an electronic survey was sent to Finnish comprehensive school teachers (N?=?2276) in order to assess the prevalence of three selected inclusive strategies: co-teaching, group work, and differentiation. The results showed that co-teaching was used by 42% and group work by 43% of the teachers at least on a weekly basis, while differentiation was used regularly by 83% of teachers. The application of all strategies was strongly associated with teacher category, with subject teachers using them less frequently than classroom teachers or special education teachers. There was a linear trend indicating that these teaching strategies were more prevalent in bigger municipalities and among younger teacher groups. Their use was also more prevalent among female than male teachers. Additionally, among classroom teachers, their usage was associated with a more positive attitude towards inclusive education. Among classroom and subject teachers, their use was also associated with a higher sense of teacher efficacy. It is suggested that subject teachers in particular need to use more versatile teaching strategies to strengthen their ability to cope with student diversity.  相似文献

An exit survey performed for graduating students is an economical way to assess the outcomes of teacher education. In this study, exit survey data were collected from eight cohorts of Finnish student teachers who graduated between the years 2008 and 2015. A final sample consisted of 1102 preservice primary and subject teachers. A 10-item scale based on INTASC standards of teacher competency was used to measure graduates’ satisfaction regarding the knowledge and experience they had attained. This paper concentrates especially on the results of subject teachers and comparisons between the two teacher categories. The profile of the participants was uneven across domains. The highest means were observed in the domain of planning, while the lowest were in the domain of special education. Factor analysis of the scale produced two factors: instructional efficacy and pedagogic efficacy. Subject teachers scored higher than primary teachers in instructional efficacy, while primary teachers exceeded subject teachers in pedagogic efficacy. Arts, crafts and physical education teachers scored higher than other subject teacher groups. The results indicated the importance of teaching practice in the formation of teacher competence. In the future special attention should be given to the domains that obtained the lowest scores.  相似文献

The current study was part of a larger project which examined teachers’ classroom practices and relationships with students’ learning engagement in primary-school education in Estonia. The focus was the role of autonomy supportive and structured teaching on learning engagement. Two primary-school teachers and their 46 students were selected for this study. The aim of the study was to explore how teachers’ classroom practices influence students’ learning engagement over two years during grade two and grade four of the educational system. Three trained observers rated classroom practices and students self-reported learning engagement. The results highlight primary students’ high-learning engagement, and did not confirm an expectation that low-autonomy-supportive teaching results in low-learning engagement in primary school.  相似文献

Female university graduates tend to have less career success than their male counterparts. Career optimism is considered a crucial predictor of future career success, but little is known about predictors of career optimism. Based on Social Cognitive Career Theory (SCCT), we hypothesised that both perceived lecturer support and perceived career barriers impact career optimism via students’ self‐efficacy, and differentiated the model along gender lines using a subgroup path analysis. Two hundred and thirty‐two undergraduate psychology students from German universities answered an online questionnaire. Results revealed that the expected indirect effect of perceived lecturer support and perceived career barriers on career optimism via self‐efficacy was only identifiable in women. For men, we found a direct connection between perceived lecturer support and career optimism, as well as that an increase in perceived career barriers reduced males’ self‐efficacy. We were unable to identify any sex differences in career optimism.  相似文献
