In addition to its traditional task of generating and transmitting knowledge in all fields, the university has been called upon to shoulder the tasks, of economic and social development. Although these tasks have only recently been formally recognized and clearly stated, they have always been implicit. That this is so is proved by the fact that as European societies democratized and industrialized themselves in the nineteenth century, increasing numbers and varieties of non‐traditional higher education institutions came into being, directed at the aims of the self‐promotion of students from non‐élite backgrounds. Increasingly, all aspects of science and society are intertwined with an increasingly varied assortment of higher education institutions and programmes. A major question faced by all planners of higher education, particularly of under‐graduate curricula, is that of specialized training versus general education. Given the rapid pace of technological change, the latter seems better as a means of preparing graduates for a lifetime of coping with change. Still the traditional role of universities of creating and advancing knowledge has not been neglected, for universities or at least their graduates who are employed in specialized academies or research centres are still the intellectual and scientific pace‐setters of the world.  相似文献

Short and long‐term effects of a treatment for dyslexia are evaluated. The treatment is based on psycholinguistic theory and assumes that dyslexia is due to poor lexico‐phonological processing of words. The treatment is computer‐based and focuses on learning to recognise and to make use of the phonological and morphological structure of Dutch words. The results of the treatment were clear improvements in reading words, reading text and spelling. Effect sizes of standardised treatment gains were large (Cohen's d>0.80 for all variables). Following the treatment, participants attained an average level of text‐reading and spelling. The attained level of reading words and reading text was found to be stable over a four‐year follow‐up period. Spelling showed a slight decline one year after the treatment, but remained stable thereafter. 1 1. A preliminary report of the data was presented at the World congress on dyslexia, September 1997, Thessaloniki, Greece.  相似文献

This study examined how timing (i.e., relative maturity) and rate (i.e., how quickly infants attain proficiency) of A‐not‐B performance were related to changes in brain activity from age 6 to 12 months. A‐not‐B performance and resting EEG (electroencephalography) were measured monthly from age 6 to 12 months in 28 infants and were modeled using logistic and linear growth curve models. Infants with faster performance rates reached performance milestones earlier. Infants with faster rates of increase in A‐not‐B performance had lower occipital power at 6 months and greater linear increases in occipital power. The results underscore the importance of considering nonlinear change processes for studying infants’ cognitive development as well as how these changes are related to trajectories of EEG power.  相似文献

Direct observation of behaviors is a data collection method customarily used in clinical and educational settings. Repeated measures and small samples are inherent characteristics of observational studies that pose challenges to the numerical estimation of reliability for observational data. In this article, we review some debates about the use of Generalizability Theory in estimating reliability of single‐subject observational data. We propose that it could be used but under a clearly stated set of conditions. The conceptualization of facets and object of measurement for a common design of observational research is elucidated under a different light. We provide two numerical examples to illustrate the ideas. Limitations of using Generalizability Theory to estimate reliability of observational data are discussed. © 2007 Wiley Periodicals, Inc.

Abstract

The crucial role of teacher-student relationships has been reported in many studies. Yet, how teacher-student relationships develop from moment-to-moment interactions during lessons remains understudied. The present study combined insights from interpersonal theory and dynamic systems approaches to study indices of interpersonal content and structure in teacher-student interactions and their association with the teacher’s interpersonal style. We found that moment-to-moment teacher behavior was indeed related to student perceptions of the teacher’s interpersonal style. Indices of variability (structure) in interactions discriminated between teachers with less preferred and more preferred interpersonal styles, while, contrary to earlier research, the indicator of predictableness of interactions could not. Results are discussed considering the expectations, and suggestions made for future research and practice.  相似文献

This article tests a longitudinal model of the antecedents and consequences of changes in identification with indigenous (Mapuche) among indigenous and nonindigenous youth in Chilean school contexts over a 6‐month period (633 nonindigenous and 270 Mapuche students, Mages = 12.47 and 12.80 years, respectively). Results revealed that in‐group norms supporting contact and quality of intergroup contact at Time 1 predicted student's changes in Mapuche identification at Time 2, which in turn predicted changes in support for adoption of Chilean culture and maintenance of Mapuche culture at Time 2; some of the relationships between these variables were found to be moderated by age and ethnicity. Conceptual and policy implications are addressed in the Discussion .  相似文献

Educating students with behavioural, emotional and social difficulties requires a thorough systematic approach with the focus on academic instruction. This study addresses the development of a tool, consisting of two questionnaires, for measuring systematic academic instruction. The questionnaires cover the Plan‐Do‐Check‐Act cycle and academic versus behavioural instruction. The questionnaires are both practically oriented as well as theoretically well founded. The reliability turned out to be acceptable (0.76) to high (0.89). Observation scales were developed to determine the validity of both questionnaires. Moderate correlations between questionnaires and observation scales were found (0.31, 0.32). Bland–Altman plots offered us valuable information about the differences between questionnaires and observation scales, supplying us with important issues for further research. It is concluded that the questionnaires might be a valuable tool for assessing teachers' systematic academic instruction.  相似文献

This study investigated whether videotape‐mediated instruction has any effect on the learning of the principles of audiovisual instruction, and on the development of practical skills. A total of 100 students were used as the sample population, 50 students (control group) receiving lectures on the selected concepts and the other 50 (experimental group) receiving both videotaped and lecture‐based instruction. Results indicated that the experimental group gained more, in general, than did the control group.  相似文献

The aim of this study was to understand the relationships between self‐compassion, positive affect, negative affect, and variables representative of positive body image for college women. Regression analyses indicated that self‐compassion and affect accounted for 39% and 30% of the variance, respectively, in body appreciation and body image quality of life. Mediational analyses demonstrated that positive affect mediated the relationships between self‐compassion and both indicators of body image. Implications for college counseling are discussed.  相似文献

Visual instruction complementing verbal lectures is known to promote learning among students. In this study, the role of visual instruction in engaging learners effectively via the simplification of technical concepts was examined. Different aspects of visualisation, such as order of presenting and dimensionality, were tested to observe their effect on students’ approach to learning and learning outcomes. In this mixed‐method quasi‐non‐experimental explanatory study, visual instruction was applied in one of the undergraduate architecture modules that teaches fundamentals of building systems, which students often find difficult to comprehend. Three key variables, including spatial cognitive ability, approach to learning and learning outcomes, were measured using statistically valid instruments along with students’ feedback and interviews. These factors were also measured for the control group that did not receive visual instruction (n = 32), to assess the effect of the intervention. When taught with visualisation, students (n = 69), showed a significant increase in deep approach to learning (e.g., deep motive: t = 2.584, p = 0.011). In interviews, students expressed a deeper interest in the subject and reported that the topic was engaging in class. Visualisation favours students with a higher spatial ability and, thus, is useful for design students who receive spatial ability training in the course. Two‐dimensional visuals must be followed and preceded by three‐dimensional visuals to provide advanced organisation and the connection of new knowledge with known organisational models to be made.  相似文献
