INTRODUCTION In this paper, we propose an automatic target tracking method in our real-time simulation and animation system of large-scale terrain field. Our system supplies autonomous guidance, navigation and control of moving objects, in order to efficiently perform related challenging missions in manufacture, entertainment, and other real-world applications. Our goal is to deploy a large number of moving vehicles upon a large-scale virtual terrain (essentially a 2D curved terrain surfa… 相似文献
We sought to determine what types of linguistic information children represent in their spelling by examining their performance on the flaps of words such as city and lady . In 4 experiments, children often misspelled flaps as d . This d bias was common until at least second grade, with few children showing a bias toward t . We found no evidence that children have an underlying representation of city as containing /t/, for children said such words with /d/ when speaking very slowly. Even kindergartners were more accurate at spelling the flaps of words such as dirty , which have a stem ending with /t/, than the flaps of words such as city . Thus, children use meaning relations among words to aid their spelling before they have formally been taught to do so. The results show that young children are not purely phonetic spellers as they are often portrayed. The results further suggest that phonology and orthography are closely related systems that interact during development. 相似文献
Student evaluations are a common source of information used by instructors and administrators, but their utility depends on students’ motivation and attention. This paper presents evidence from two studies indicating that insufficient effort responding and lack of motivation may be problems in course evaluations. In the first study, approximately one in four students responded in an improbable way to ‘catch items’ embedded in actual course evaluation instruments, suggesting a lack of attention. In the second study, students’ responses to an online survey indicated that they doubted that their responses to course evaluations would be used by instructors or administrators. The majority of students admitted to only occasionally putting sufficient effort into their responses. Potential means for identifying insufficient effort responding and mechanisms for increasing student attention and motivation during the course evaluation process are discussed. 相似文献
Faculty in the School of Education have collaborated to re-envision teacher education at our university. A complex, dynamic, time-consuming and sometimes painstaking process, redesigning a teacher education program from a traditional approach (i.e. where courses focus primarily on theoretical principles of practice through textbooks and university-based classroom discussions) to a model of teacher education that embraces teaching, learning and leading with schools and in communities is challenging, yet exciting work. Little is known about teacher educators’ experiences as they either design or deliver collaborative field-based models of teacher education. In this article, we examine our experiences in the second implementation year of our redesigned teacher education program, Teaching, Learning, and Leading with Schools and Communities (TLLSC) and how these unique experiences inform our teacher educator identities. Through a collaborative self-study, we sought to make meaning of our transformation from a faculty delivering a traditional model to educators collectively implementing a field-based model, by analyzing the diverse perspectives of faculty at different entry points in the TLLSC development and implementation process. We found that our participation in an intensive field-based teacher preparation model challenged our notions of teacher educator identity. In a culture of iterative program design, this study documents the personal and professional shifts in identity required to accomplish this collaborative and dynamic change in approach to teacher education. 相似文献

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers’ ability to effectively implement technologically engaged modules in a flipped classroom setting. Competencies were identified via participatory evaluation techniques and assessments were aligned to the competencies. The competency of teachers in the knowledge, skills, and abilities needed for creation and delivery of effective flipped lessons can be tracked using a radar graph to guide tailored professional development.

High equipment and materials costs, limited access to computers for instruction in many schools, and the success of cooperative learning strategies in traditional classroom instruction have prompted researchers to examine the potential of cooperative computer-based instruction (CBI). In this article, recent research on cooperative CBI is reviewed and findings related to achievement, patterns of study, social interchange, motivation, and gender are discussed. In addition, guidelines on the implementation of cooperative CBI that have been gleaned from the literature are presented.This paper was prepared with partial support from MECC/University of Minnesota Center for Study of Educational Technology, and presented at the AECT Annual Convention, January 31–February 4, 1990, Anaheim, CA. 相似文献
Many clients requesting assistance in Career Centers are mismatched with their career due to issues of occupational choice. In addition, personality conflicts with co-workers, lack of interpersonal skills, and the individual's personality characteristics can affect vocational success. Theories of personality are incorporated into several theories of vocational choice and development (i.e., Holland, Roe) resulting in some attention to personality. Likewise, client personality can affect the career counselor's ability to intervene effectively to assist the client in making effective career choices and decisions. More direct attention to the impact of personality on an individual's career and vocational success can enable the Career Center to increase the effectiveness of their interventions. This paper will discuss the methods for increasing the effectiveness of career counseling through the use of the Five-Factor Model of Personality into our therapeutic work with clients. 相似文献
