The impact of communication apprehension on college student retention and success     

James C. McCroskey  Steven Booth‐Butterfield  Steven K. Payne 《Communication quarterly》2013,61(2):100-107

Communication apprehension is conceptualized as a causal agent in student success. It is implicated in both academic and interpersonal success, two factors identified by prior resesarch as primary predictors of persistence. A four year longitudinal study of the impact of communication apprehension on grade point average and persistence at the university level was conducted. Results indicated high CA students were significantly more likely to drop out and attain lower grade point averages compared to low CA students. The impact of CA was strongest during the first two years. A replication of the study confirmed the impact of CA on student persistence. It is concluded the impact of CA on the probablity of high CA students’ survival in college is substantial and this impact adds to the case favoring the provision of training programs to assist such students overcome their apprehension about communication.  相似文献   

At the Precipice: The Story of Mathematics Education in the United States     

Brandyn L. Payne 《Peabody Journal of Education》2013,88(1):133-153

The role of education in fostering economic growth and social development is universally recognized. Although history places the provision of education firmly within national control, countries increasingly search outside national borders for alternative distribution frameworks. Tellingly, the World Trade Organization recently included education as service trade sector in the General Agreement for Trade in Services (GATS) negotiations. Such activity increases debate about control as countries struggle to create policies that balance nationalism with economic responsiveness. This study employed multivariate data to question whether trade openness in 162 countries was associated with openness to trade in education, and whether countries' commitments to lower barriers to education trade paralleled the strength of their commitments to lower barriers to all trade.

Among the findings were the following: (a) On average, countries with education commitments experienced slightly higher levels of general trade openness than those without education commitments; (b) in lower-middle-income countries, education trade openness and general trade openness were positively related; and (c) when controlling for education, population, geography, and income, lower levels of education trade barriers were the single best predictor of countries' having made education commitments under GATS. A model for systemic improvement in education trade policymaking is also presented.  相似文献   

Design and optimization of a double-enzyme glucose assay in microfluidic lab-on-a-chip

An electrokinetic driven microfluidic lab-on-a-chip was developed for glucose quantification using double-enzyme assay. The enzymatic glucose assay involves the two-step oxidation of glucose, which was catalyzed by hexokinase and glucose-6-phosphate dehydrogenase, with the concomitant reduction of NADP⁺ to NADPH. A fluorescence microscopy setup was used to monitor the different processes (fluid flow and enzymatic reaction) in the microfluidic chip. A two-dimensional finite element model was applied to understand the different aspects of design and to improve the performance of the device without extensive prototyping. To our knowledge this is the first work to exploit numerical simulation for understanding a multisubstrate double-enzyme on-chip assay. The assay is very complex to implement in electrokinetically driven continuous system due to the involvement of many species, which has different transport velocity. With the help of numerical simulation, the design parameters, flow rate, enzyme concentration, and reactor length, were optimized. The results from the simulation were in close agreement with the experimental results. A linear relation exists for glucose concentrations from 0.01 to 0.10 g l⁻¹. The reaction time and the amount of enzymes required were drastically reduced compared to off-chip microplate analysis.  相似文献   

A double win: practice and participation in an action learning facilitators’ set     

Nicola Wilson 《Action Learning: Research and Practice》2019,16(2):178-186

This account of practice shares insights from past and present members of a self-facilitating action learning set, where each of the members is an action learning facilitator. Motivations for joining the set encompassed the opportunity to ‘practice what you preach’ by being a set member as well as a facilitator, the potential to refine and develop facilitation practices in a safe environment and space for personal development.  相似文献

Volunteers in Australian archives     

Annelie de Villiers  Nicola Laurent  Christopher Stueven 《档案与原稿》2017,45(2):118-135

Why do volunteers choose to contribute thousands of unpaid hours per week to Australian archives? This paper presents the results of a nationwide web survey that provides insight into the demographics, motivations and experiences of volunteers in Australian archives. The findings provide a representative overview of formal volunteers in Australian archives, determining ‘who’ they are, the value of the contributions they provide and the level of training and support offered to them. This study is a continuation of existing discussions about volunteers in Australian archives and represents an opportunity for the development of stronger relationships with Australian archival volunteers and, through them, the communities our archives serve.  相似文献   

Development of Hybrid Courses Utilizing Modules as an Objective in ATE Projects     

James E. Payne  Richard M. Murphy  Linda L. Payne 《Community College Journal of Research & Practice》2017,41(6):366-369

ABSTRACT

Orangeburg-Calhoun Technical College (OCtech) has been awarded two National Science Foundation Advanced Technological Education (NSF-ATE) grants since 2011 that have the development of module-based hybrid courses in Engineering Technology and Mechatronics as objectives. In this article, the advantages and challenges associated with module-based hybrid courses are discussed. The courses that have been developed deal specifically with alternative energy and robotics. Through modularizing the courses, instructors throughout OCtech may elect to use materials from these courses to supplement face-to-face courses or offer the entire course in a hybrid format. In addition to being used in the college’s traditional curriculum, these courses have been utilized in the Middle College and the Flex/Evening College for working adults with great success. The courses and the included modules are housed on a Learning Management System hosted by OCtech that is available to all the colleges and high schools in the state.  相似文献
