ABSTRACT In this article, the authors introduce a novel way, using the metaphor of a baseball game, to evaluate and measure community college student progress for those whose stated goal is to transfer to a 4-year institution and, ultimately, earn a bachelor's degree. The proposed framework of “the Transfer Game” is an outgrowth of the Transfer and Retention of Urban Community College Students (TRUCCS) project, which is a longitudinal study of 5,000 community college students from the 9-campuses of the Los Angeles Community College District. The goal of the project is to explain how the “all-American game” provides a method to measure, comprehend, and visualize student progression, and identify the factors that predict both success and barriers. The framework provides a scholarly comparison of the all-American game of baseball to the All-American invention of the community college. 相似文献

In this paper, we consider the super-twisting observer-based sliding mode control algorithm with fuzzy variable gains (STOSMC) for the fully-actuated hexarotor. Our hexarotor has full actuation due to six titled propellers that allows to control position and orientation (attitude) simultaneously, and resolves the singularity problem of the rotational matrix by using the quaternion modeling framework. We show that the proposed STOSMC for the hexarotor guarantees finite-time convergence of the estimation error and asymptotic stability of the hexarotor. In simulations, we demonstrate the nonsingularity and fully-actuated control performance of the hexarotor by considering extreme position and attitude control scenarios. Moreover, the simulation results show that the hexarotor achieves the fast and precise tracking performance to the desired position and the desired attitude and the chattering phenomenon is reduced compared with the fixed-gains observer-based super-twisting sliding mode control due to the fuzzy mechanism. 相似文献

Expression and Reception: An Analytic Method for Assessing Message Production and Consumption in CMC
Kang Namkoong Dhavan V. Shah Bryan McLaughlin Ming-Yuan Chih Tae Joon Moon Shawnika Hull 《Communication methods and measures》2017,11(3):153-172
This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks. 相似文献

This paper suggests that teacher education is undergoing significant transformation. In most countries there is a recognition that the quality and extent of provision will need to be raised. Open and distance education, utilising new interactive forms of technology, will have a crucial, perhaps major, role to play in this process. The school will act increasingly as a ‘site’ for learning within evolving models of initial and in‐service teacher education. All forms of teacher education will exploit new technologies. There will be an increasing convergence between conventional and open and distance modes of delivery. New assessments of costs and effectiveness will need to be made. Changes in technology has rendered ‘out‐of‐date’ much of the previous evaluative evidence. National and international expertise in open and distance education, new methodologies and teacher education will need to be developed. 相似文献

Information from 422 cases of child mistreatment in Toronto was gathered from the files of a child welfare agency and a children's hospital. These data were compared to patterns reported in previous studies and clinical writings on child mistreatment to investigate similarities and differences in families whose children have been abused in Canada, England, and the United States. Findings from the present study were similar to others in many respects. The differences were primarily in the area of lower incidences of such problems as perinatal difficulties in the children and intellectual limitations and social isolation in the parents; however, there was a higher incidence of single-parent families. The results suggest that clinicians should bear in mind that child mistreatment cannot be ruled out on the grounds that no serious problems have been noted for the child or the family. 相似文献

Education reform and competency-based education 总被引:2,自引:0,他引:2
Yong-lin Moon 《Asia Pacific Education Review》2007,8(2):337-341
The core purpose of this paper is to describe a new educational paradigm as well as possible directions and tasks for education reform in the 21st century. The present-day education system has failed to nurture the kind of creative people who can play leading roles in development or to produce citizens of a good character and democratic tendencies. We need to look at education from the standpoint of expanding the totality of possibilities for national development. The current educational system of Korea can be characterized as one of “manpower-centered education. ” In this system, education functions to produce the human resources needed by the nation, and there is a strong belief in the classification and selection of high-quality human capital via the school system. We can think of an educational model that is parallel to the current system of manpower classification and selection and call it “competency-based education. ” In this model, the identification of individual ability, talent, and aptitude is deemed to be the most important, and the key task of education is self-actualization through recognition and cultivation of such talents and abilities. What educational values should be pursued within a new competency-based paradigm? First, we can reduce the relative weight of subject-centered education and introduce a competency-based curriculum in order to teach key competences for life. Second, new intelligence theories must be introduced into education in order to foster the development of students' talents, aptitudes, and potentials. Third, we can make use of positive psychology, which is a newly emerging field, the core concept of which is the belief that happiness in life depends on one's ability to develop and maintain positive feelings and emotions. 相似文献

Concerns that students increasingly come to tertiary studies ill‐prepared for academic pursuit in the disciplines have generated a broad range of supplementary tuition in Australian Universities during the past decade. Many researchers and tertiary teachers have from experience realized that tertiary learning skills are very much context‐, or discipline‐specific. This paper is concerned with making context‐specific expectations known to students through a process of ‘showing how’, rather than ‘telling what’. Two highly specialized teaching structures were used to generate appropriate questions for students, thereby providing parameters for their search and research and ultimately, their writing in the discipline. 相似文献

Forward citations of patents have been used extensively to capture the impact of technological knowledge. However, our understanding of the factors shaping patent citation patterns remains limited. One of the main limitations is the lack of scholarly attention paid to the dynamic influences arising from the evolution of technology fields. From an evolutionary perspective, technological impact is not simply determined by the static attributes of a technology itself; it is also dynamically affected by changes in the external conditions. Drawing on this viewpoint, this study suggests a model for understanding patent citation patterns by reflecting the evolution of the technology fields to which each patent belongs. Four such factors are explored: technology cycle time, potential of technological convergence, popularity of the technology field, and technological novelty. Based on the proposed model, we show how expected citation patterns can change as a result of different scenarios for technology field evolution. We conduct a case study of patents in the information technology and healthcare industries to show citation patterns of patents across heterogeneous industries as well as those within an industry. Contributions to the innovation literature and research investment decisions are discussed. 相似文献

This study examined how news organizations employed Twitter as a news source, based on information subsidy and gatekeeping perspectives. News content analysis from 7 major media entities in 2010–2011 demonstrated that journalists embraced Twitter as a new channel for information gathering. TV frequently cited Twitter as a sole or a primary source. However, despite active usage of Twitter overall, journalists in both TV and newspapers maintained conventional routines by relying primarily on Twitter accounts of official sources. The popularity of Twitter accounts, as indicated by the number of followers, did not contribute to attracting more attention from journalists. 相似文献
