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

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil… 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

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

The present study examined the types of orthographic knowledge that are important in learning to read and spell Chinese words in a 2‐year longitudinal study following 289 Hong Kong Chinese children from Grade 1 to Grade 2. Multiple regression results showed that radical knowledge significantly predicted children's word reading and spelling performance across the years. Stroke knowledge contributed both concurrently (Grade 1) and longitudinally (Grade 2) to children's spelling performance after controlling for rapid naming, phonological awareness, morphological awareness and radical knowledge. These findings support the significance of radical knowledge in Chinese reading and spelling and the specific role of stroke order knowledge in Chinese spelling. The findings have implications for the design of an effective curriculum for teaching children to spell Chinese characters. 相似文献

In this paper, a semantic categorization method in generic home photos is proposed. In recent years, the semantic categorization of image has been a challenge due to the proliferation of digital home photos. Our approach is to detect semantically meaningful concepts contained in a photo. The proposed method incorporates an intermediate level of concepts, called local concept, so that it catches well semantic meaning of local regions of image as bridging the semantic gap of the low-level features and high-level category concepts. To detect the local concepts from the home photo, region segmentation by photographic region template and concept merging is also proposed. The efficacy of the proposed semantic categorization method was demonstrated with 3828 general home photos. The experiment results showed the proposed categorization method would be useful to detect multiple semantic meaning of the home photos. 相似文献
