In this paper quality of graduates is distinguished from quality of education, which is renamed efficiency of education. The first concept is defined in a quantitative manner, the second by way of a set of 66 statements concerning the efficiency of education derived from judgements about the effectiveness of particular teaching methods in the achievement of different types of teaching objectives.Paper presented at the conference on Efficiency of Teaching Methods in Higher Education, organized by the University Teaching Methods Unit of the University of London, 6–7 April, 1976.  相似文献

This article describes a study of the experiences of 610 Dutch students and 241 European students who studied at least three months abroad within the framework of an international exchange program. The Dutch students went to a university in another European country and the foreign students went to a Dutch university. Using a new questionnaire called the Inventory of Perceived Study Environment (IPSE), students, perceptions of eight characteristics of the university learning environment were measured concerning the home university, the host university and the ideal learning environment. With this instrument, the learning environment can be described in terms analogous to the learning strategies performed. Large differences were found between the different countries in university learning environments, but students from different countries had strikingly similar opinions concerning their desired learning environment. There was a strong preference for activating instruction with a low threshold in teacher-student interaction and more room for student alternatives.  相似文献

Community-based health and human services professionals can play an important role in bolstering wellness through offering education to elderly residents and healthcare providers on how to address the unique needs of this population. The purpose of this study was to examine the healthcare needs of the elderly living in two metropolitan counties in Georgia that have experienced an increase in the number of elderly residents. Utilizing qualitative data garnered through focus groups, two main themes were identified: the role of exercise as a means of personal power and feelings of powerlessness. Participants’ narratives reflected opportunities and situations fostering good health through exerting their personal power to alter or improve individual health. On the other hand, negative pathways leading away from optimal health were realized when participants felt powerless to change their health status. For health and human services professionals working with the elderly, these findings should be considered as population, personal well-being, and power changes overtime.  相似文献

The term ‘hypervideo’ has different interpretations in the scientific literature. The aim of this contribution is to define hypervideo as it is and can be (more optimally) used for teaching and learning purposes. Videos can promote learning by recreating real experiences and dynamic processes, although they do not necessarily enable students to interact with contents and to self-regulate their learning. Hypervideos technically overcome these limitations and add further benefits. However, even though some literature on the topic exists, the concept of hypervideo is not well represented in the scientific community and lends itself to different interpretations. Results show that hypervideo is defined as a dynamic artefact, it should allow navigation control and include additional material; it could also integrate individual or collaborative annotation and automated or manual feedback. So far, most studies have been conducted in artificial settings involving tertiary-level students. Finally, its use is beneficial for students’ learning.  相似文献

In an earlier study we found that intermediate experts in the domain of economics did not surpass novices in complex learning and knowledge application with a computer-based business simulation. In the present study, it was investigated whether these contra-intuitive findings can be replicated. In order to scrutinize the reasons which led to these findings, some parameters of the learning environment were changed. The duration of the exploration phase and of the problem-solving phase as well as the complexity of the situations were increased, motivation and acquired declarative knowledge were assessed. In view of mastering recurring demands and the functionality of mental models, no differences were found between a group of novices (15 students of humanities with a supplementary training in economics) and a group of intermediate experts (13 advanced students of economics). The findings of the original study were replicated, motivation had no effect on the result. In terms of declarative knowledge, the novices turned out to be even better.  相似文献

Cut‐scores were set by expert judges on assessments of reading and listening comprehension of English as a foreign language (EFL), using the bookmark standard‐setting method to differentiate proficiency levels defined by the Common European Framework of Reference (CEFR). Assessments contained stratified item samples drawn from extensive item pools, calibrated using Rasch models on the basis of examinee responses of a German nationwide assessment of secondary school language performance. The results suggest significant effects of item sampling strategies for the bookmark method on cut‐score recommendations, as well as significant cut‐score judgment revision over cut‐score placement rounds. Results are discussed within a framework of establishing validity evidence supporting cut‐score recommendations using the widely employed bookmark method.  相似文献
