This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations. 相似文献

The use of "interactive storybooks" in the primary classroom may facilitate small group and individual reading with minimal teacher intervention. This small-scale study examines whether small groups of Year 5 pupils, without teacher supervision, progress linearly through an "interactive storybook" and whether such diversions as cued animations affect pupil comprehension. The study finds that more intensive choice of diversions affects some pupils' comprehension. 相似文献

This article compares traditional college students' perceptions of effective teaching behaviors with nontraditional students' perceptions. A 15-item questionnaire was completed by undergraduates at a small Southeastern university. Nontraditional students viewed personality and interaction behaviors as more indicative of effective teaching, whereas traditional students focused on behaviors that potentially would enhance grades. The implications of the findings are discussed in light of techniques and approaches that facilitate the needs of both types of students.His major areas of interest include testing and counseling. Nina Mattie, M.A. is a recent graduate of the University of West Florida in the area of school psychology. Stephen J. Vodanovich, Ph.D. is an assistant professor in the psychology department at the University of West Florida. His major areas of interest are social psychology and industrial/organizational psychology. Chris Piotrowski, M.A. is a consultant in forensic psychology. His major areas of interest are personality assessment and online database searching. 相似文献

Discussions of the functions of institutional research are common. However, discussions concerning the structures associated with disciplined inquiry, theresearch part of institutional research, have been rare. This paper compares the process and structure of institutional research with three ways in which science is conceptualized. These comparisons result in the recognition that although institutional research has much in common with science, it is distinct from science. This paper begins the process of identifying the structures and assumptions that form the basis of institutional research.Presented at the Thirty-First Annual Forum of the Association for Institutional Research, San Francisco, May 26–29, 1991 相似文献

Although the tradition of bicameral governance is well established in Canada's universities, in no province do community colleges operate under a similar principle. In fact, there is no statutory role for college faculty in governance, either through a senate or a senate-like body. This article argues the case for greater democracy in the governance of colleges and, in doing so, analyzes the role of college governance. The conclusion reached is that, while more democratic and participatory governance may be argued on conceptual grounds, it would also improve morale, trust, and communication within the college sector. 相似文献

Mapping the curriculum of a professional degree to the associated competency standard ensures graduates have the competence to perform as professionals. Existing approaches to competence mapping vary greatly in depth, complexity, and effectiveness, and a standardised approach remains elusive. This paper describes a new mapping software tool that streamlines and standardises the competency mapping process. The available analytics facilitate ongoing programme review, management, and accreditation. The complete mapping and analysis of an Australian mechanical engineering degree programme is described as a case study. Each subject is mapped by evaluating the amount and depth of competence development present. Combining subject results then enables highly detailed programme level analysis. The mapping process is designed to be administratively light, with aspects of professional development embedded in the software. The effective competence mapping described in this paper enables quantification of learning within a professional degree programme, and provides a mechanism for holistic programme improvement. 相似文献

A new word-learning phenomenon is demonstrated and a new word-learning principle is proposed to account for it. In Study 1, 60 3-year-olds were shown a pair of objects and heard a novel label used repeatedly for one, but not for the other. In a forced-choice test of generalization of the label, the latter object was selected less often by the children than one that had not been present during training. This so-called Nominal Passover Effect was the same whether the speaker had completely ignored the comparison object during training or had referred to it with pronouns. The performance of a no-word control group ( N = 24) indicated that the effect was not due to a preference for the less exposed of the two choice objects. The effect is consistent with the Exhaustive Reference Principle, which stipulates that whenever a new generic word is used to name something, expect it to be extended to all entities in a situation that the speaker perceives and believes to be exemplars of the name. In Study 2 ( N = 48), the Nominal Passover Effect was replicated with 3 new sets of objects and with training language that contained only indefinite forms of reference. The passover experience was often sufficient to counteract children's tendency to generalize a novel label on the basis of perceptual similarity. The passover effect was not evident in free-choice name generalization tests in either study. 相似文献

Reading literacy and reading interest was examined in four primary schools in Papua New Guinea: in an international, suburban, settlement and village school. In this paper we present a summary of findings located within a local context and examine the implications as viewed through two lenses. From an ‘educational for equality’ perspective, the findings suggest a critical need to re‐evaluate the use of national testing to select children for further education and address the serious shortage of reading books in school libraries. From an ‘education for life’ perspective, the findings indicate a continuing need for community‐based actions together with innovative teacher education programs aimed at developing ways of strengthening the connections between home and school. 相似文献

If freezing underlies barpress conditioned suppression, then it seems odd that auditory cues paired with shock evoke more freezing than do visual cues, yet evoke similar suppression. Bevins and Ayres (1992) found that auditory and visual cues also evoked similar withdrawal from the bar and dipper areas and suggested that such withdrawal could explain the similar suppression. Seeking to understand that withdrawal, we found evidence in the present study that it was due either to adventitious punishment or to place-aversion learning. The cue for shock seemed to set the occasion for such learning. For example, we found that, as training progressed, rats’ tendency to leave the bar area during the cue first increased, then decreased, then increased again, reflecting, presumably, shock occurrence first inside, then outside, then inside the bar area again. Despite these changes in the rats’ location, barpress suppression remained stable, implying that leaving the bar area, though sufficient for barpress suppression, is unnecessary. 相似文献
