The elaboration theory of instruction: A model for sequencing and synthesizing instruction 总被引:1,自引:2,他引:1

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

As a country with a relatively small international reputation for manufacturing and, apparently, with an even smaller one for technology-based product and process innovation in manufacturing, Canada has a long way to go to develop its manufacturing and innovative activities to the stage reached by most European countries. Recently, however, a number of science and research policy studies have been made to examine problems associated with innovation in manufacturing. This present paper deals with two important elements associated with these studies, namely, the organization of the public sector in Canada and the roles and responsibilities of the public sector agencies with regard to the encouragement of technology-based innovation in manufacturing. As pointed out in the paper, the federal structure and the agencies within it may at present frustrate as well as encourage innovation. However, assuming that the appropriate policy objectives can be articulated and accepted, the removal of the principal public sector frustrations will be dependent upon better divisions of responsibility and labour between the three levels of government. 相似文献

This paper describes the development and evaluation of an interactive, narrative-based, multimedia game to promote learning and communication about sexual violence and health topics. High school-aged participants created the game concept in a three-week workshop, after which assets were assembled and refined by a university-based game design lab. The outcome, Lucidity, was a multimedia game with a nonlinear narrative that led to two different outcomes based on player decisions. The narrative followed the life of one character, an African American woman named Zaria who remembers and grapples with a sexual assault from her past. The player discovers parts of the story by reading comics, watching videos, navigating interactive websites and playing short videogames. The final evaluation consisted of gameplay, a post-game focus group and follow-up interviews. Twenty-four young people participated in three focus group discussions (n = 9, n = 5, n = 10); 23 participated in the follow-up interviews. Salient themes identified in the focus group discussions included: overall approval of the game, the acquisition of new knowledge and minimal past exposure to conversations or education about sexual violence. At follow-up, almost all (n = 22) had initiated a conversation about sexual violence with a parent, peer and/or teacher. Lucidity succeeded in engaging young people and facilitating communication with adults and peers regarding sexual violence and other sexual health topics. Ultimately, a game-based intervention such as this represents a feasible approach for introducing issues of sexual violence, with potential for future implementation in educational settings. 相似文献

In Leonard Koos’s book, The Junior-College Movement, he described the establishment of a junior college in an American public school district as the ‘culmination of the local school system’, alluding to the prestige associated with having a junior college in a community. The best-known example of this arrangement was in Pasadena, California where the combined high school and college operated for 27 years. Less well known is the four-year junior college in central Missouri called Moberly Junior College (MJC). MJC operated as a combined high school and college for 36 years from the autumn of 1931 to the autumn of 1967, the longest running four-year junior college in the United States. This case study of the college examines how the seamless transition between high school and college was accomplished, and what changes in the institution and the educational environment led to the eventual dissolution of the four-year junior college. 相似文献

There has been a limited interest in examining physical education teacher educators’ role and practices in embedding professional responsibility and commitment to continued professional learning for both teacher educators and pre-service teachers in a physical education teacher education (PETE) program (MacPhail, 2011) Directed by a landscape of community of practice (CoP) as professional development (Parker, Patton &; Tannehill, 2012), this article shares four case studies that demonstrate the extent to which PETE learning can be mapped onto the landscape. In essence, a CoP is sustained over time, involves shared member goals, involves frequent discourse, is active and social, and is characterized by problems being solved by the members. The ideas in this article in tandem with Wenger's (1998) CoP process can encourage teacher educators to consider whether opportunities undertaken in a PETE program, and with colleagues external to the PETE program, encourage an authentic CoP. 相似文献

The use of three‐dimensional (3D) models for education, pre‐operative assessment, presurgical planning, and measurement have become more prevalent. With the increase in prevalence of 3D models there has also been an increase in 3D reconstructive software programs that are used to create these models. These software programs differ in reconstruction concepts, operating system requirements, user features, cost, and no one program has emerged as the standard. The purpose of this study was to conduct a systematic comparison of three widely available 3D reconstructive software programs, Amira®, OsiriX, and Mimics®, with respect to the software's ability to be used in two broad themes: morphometric research and education to translate morphological knowledge. Cost, system requirements, and inherent features of each program were compared. A novel concept selection tool, a decision matrix, was used to objectify comparisons of usability of the interface, quality of the output, and efficiency of the tools. Findings indicate that Mimics was the best‐suited program for construction of 3D anatomical models and morphometric analysis, but for creating a learning tool the results were less clear. OsiriX was very user‐friendly; however, it had limited capabilities. Conversely, although Amira had endless potential and could create complex dynamic videos, it had a challenging interface. These results provide a resource for morphometric researchers and educators to assist the selection of appropriate reconstruction programs when starting a new 3D modeling project.

Abstract Over the past decade, educational policy in Britain, as in other industrial nations, has been increasingly driven by the concern that higher education should serve the needs of the economy more effectively. The report Highly Qualified People: supply and demand reflects this concern and attempts to establish from employers Britain's likely requirement, in the 1990s, for such expensively educated labour. Though the report concluded that Britain needed more graduates over the next few years, closer scrutiny of its data suggests a very different conclusion ‐ not that Britain needs more graduates to prosper, but rather that Britain needs first to prosper before it is likely to want the graduates it already produces. 相似文献

This study draws on in‐depth interview data to discuss the school choices and educational advocacy roles of 14 African‐American mothers. The narratives of the study’s participants, who have low‐income or working‐class status, show how race, class and gender factors influence their school choice‐making and their value of education. The author asserts that the mothers’ school choice‐making constitutes an important act of cultural resistance and empowerment called motherwork. Analysis of the study’s findings challenges conventional notions of parent involvement and counters prevalent stereotypes that portray African‐American mothers as uncaring. Attention is given to the inequities that the mothers face in the educational marketplace and how they seek agency. Educators are urged to consider how the mothers perceive themselves and construct their educational involvement roles in order to engage parents in empowering and meaningful ways. 相似文献

A simple experimental setup to study the impact and coalescence of deposited droplets is described. Droplet impact and coalescence have been investigated by high-speed particle image velocimetry. Velocity fields near the liquid-substrate interface have been observed for the impact and coalescence of 2.4 mm diameter droplets of glycerol∕water striking a flat transparent substrate in air. The experimental arrangement images the internal flow in the droplets from below the substrate with a high-speed camera and continuous laser illumination. Experimental results are in the form of digital images that are processed by particle image velocimetry and image processing algorithms to obtain velocity fields, droplet geometries, and contact line positions. Experimental results are compared with numerical simulations by the lattice Boltzmann method. 相似文献
