This paper describes a novel instructional model for sequencing, syntheizing, and summarizing subject-matter content. The importance of such models is discussed, along with the need for a significant change in the role of subject-matter structure in instruction. A zoom-lens analogy is presented to facilitate an understanding of the elaboration model of instruction. Some basic concepts and principles upon which the model is based are described. The basic unvarying components of the elaboration model are described. And finally, some variations in the model for different kinds of goals are described. The elaboration model follows a general-to-detailed pattern of sequencing, as opposed to the hierarchically based sequences derived from Gagné-type task analyses.Many of the ideas described in this paper were developed under two projeets, one funded by Brigham Young University in Provo, Utah, and the other by the Navy Personnel Research and Development Center in San Diego, California; however, the ideas expressed do not necessarily constitute the opinions of the funding institutions. 相似文献
This paper asks whether the institutional hierarchies defined by ‘golden triangle’, other Russell Group, other pre-1992 and post-1992 universities in England, and by ancient, old and new universities in Scotland, have become weaker since the 1990s. Using indicators constructed from Universities and Colleges Admissions Service data for 1996–2010, the article finds a stable hierarchical relationship among the sectors within each country, with some indicators showing a slight widening of status differences between sectors towards the end of the period. The main exception was a slight ‘upgrading’ of new (post-1992) universities in Scotland early in the period. There was little change in the association of institutional sector with social class, but in England the association with private secondary schools became slightly stronger and the association with ethnicity weakened. 相似文献
El discurso argumentativo escrito tiene intrínsecamente un carácter dialàgico. Esta característica se pone de manifiesto en la contraargumentación, uno de los aspectos que mayor dificultad presenta para los aprendices, tanto en la comprensión como en la producción de textos escritos. Esta dificultad se hace patente en las actividades desarrolladas en el curso de una secuencia de enseñanza y aprendizaje sobre este tipo de discurso con alumnos de los primeros niveles de enseñanza secundaria. De ello se desprende la necesidad de su enseñanza específica. 相似文献
Herman Witkin's research in differentiation theory proposed a conceptual framework describing the cognitive style known as field dependence‐independence. The operational measures of this construct are restructuring skills and interpersonal competencies, and were originally conceived to be fixed in an individual. A recent reconceptual‐isation, however, suggested that there may be some malleability in learning strategies that flow from cognitive style. Learners predisposed to field dependence might gain access to restructuring skills brought to problem‐solving situations by field independents. This study undertook to examine the effects and practicability of restructuring training as a means of addressing individual learner differences. Field independent subjects significantly out‐scored field‐dependent subjects on all three test tasks in the control group. Experimental group field independents did not significantly outscore experimental field dependents. Training enhanced field dependent subject performance on two dependent measures tasks. There was interaction across treatment and field dependence on all three dependent measures. 相似文献
Metrics derived from user visits or sessions provide a means of evaluating Websites and an important insight into online information seeking behaviour, the most important of them being the duration of sessions and the number of pages viewed in a session, a possible busyness indicator. However, the identification of session (termed often ‘sessionization’) is fraught with difficulty in that there is no way of determining from a transactional log file that a user has ended their session. No one logs out. Instead a session delimiter has to be applied and this is typically done on the basis of a standard period of inactivity. To date researchers have discussed the issue of a time out delimiter in terms of a single value and if a page view time exceeds the cut-off value the session is deemed to have ended. This approach assumes that page view time is a single distribution and that the cut-off value is one point on that distribution. The authors however argue that page time distribution is composed of a number of quite separate view time distributions because of the marked differences in view times between pages (abstract, contents page, full text). This implies that a number of timeout delimiters should be applied. Employing data from a study of the OhioLINK digital journal library, the authors demonstrate how the setting of a time out delimiter impacts on the estimate of page view time and the number of estimated session. Furthermore, they also show how a number of timeout delimiters might apply and they argue that this gives a better and more robust estimate of the number of sessions, session time and page view time compared to an application of a single timeout delimiter. 相似文献
Over the last decade universities have been subjected to various forms of academic accountability designed to maintain or improve the quality of their teaching and learning. A shared perspective of many of these accountability processes is that universities should become skilled at creating knowledge for the improvement of teaching and learning, and at modifying their behavior to reflect this new knowledge. In short, that universities should become “learning organizations.” What are the organizational characteristics of an academic learning organization? The paper will address this question by reviewing the adaptations in organizational structure and governance reported by universities attempting to improve the quality of their teaching and learning processes. 相似文献
The situated development of South Asian communities in the UK has led to the growth of a number of schools in which ‘ethnic minority’ pupils form a majority. Such a situation throws into higher relief issues and concerns surrounding cultural transmission and encounter, and communicative competence.
This paper recounts some of the principal findings of research in which the teaching staff of a large 9‐13 middle school were interviewed individually regarding their perceptions of their South Asian pupils. The school has an almost wholly South Asian intake and is situated near the centre of a large northern city.
The teachers’ markedly deficit view of their charges is detailed and this is followed by an explanation of their constructions in microsociological terms. A model is presented which clarifies the processes by which close intercultural interaction seem to accomplish worlds as divergent.

In this paper, we examine the meaning of conversing with pedagogical agents. Previous research has focused on examining cause and effect relationships, failing to take into account the meaning of the experiences individuals have when holding a dialogue with conversational agents for educational purposes. To understand these experiences, we have conducted a phenomenological examination of what it means to converse with a pedagogical agent. In phenomenological terms, findings suggest the experience is complex, engrossing, virtual yet real, human‐like, and social. Implications for the future design, implementation, and research of conversational agents in educational and other settings are discussed. 相似文献
