An investigation into students’ disposition to the use of objectives in distance learning materials     

Olugbemiro J. Jegede  Jackie Walkington  Som Naidu 《Educational research; a review for teachers and all concerned with progress in education》2013,55(3):293-304

The use of learning objectives in study materials for external students is an instructional design strategy which is generally accepted. However, with the emergence of the constructivist paradigm in learning theory, there is the question as to whether the use of objectives, underpinned by behaviourist theory, is justified. This study was undertaken to investigate the distance education student's disposition towards objectives, with particular reference to the way they used them and to what their perceptions and expectations were. Responses to a questionnaire revealed that objectives were perceived by the majority of the students sampled as useful to their studies, and that objectives, for them, were an integral part of their learning strategy.  相似文献   

Older people in accident and emergency: the use of action research to explore the interface between services in an acute hospital     

Jackie Bridges  Julienne Meyer 《Educational Action Research》2013,21(2):277-289

This article reports on an ongoing action research study into the organisation of care for older people in a United Kingdom accident and emergency (A&E) department. The study is located at the interface between A&E and the in-patient services for elderly people (SEP) wards, and aims to work between these two services to seek improvements for change to the care of older people in A&E. Preliminary data are used in the article to explore three claims about the value of action research: action research enables an understanding of the issues from the perspectives of the different participants; action research enables work to take place that explicitly takes account of the different perspectives; and action research helps to explain the reasons for resistance to change. The analysis is used to highlight the value that action research may have in bridging gaps between services in an acute hospital.  相似文献   

Using behaviour contracts to decrease antisocial behaviour in four boys with an autistic spectrum disorder at home and at school     

Emma Hawkins  Sheri Kingsdorf  Jackie Charnock  Mariann Szabo  Edi Middleton  Jo Phillips  Grant Gautreaux 《British Journal of Special Education》2011,38(4):201-208

This article describes how a behaviour contract has been implemented to achieve positive and enduring results for four boys with a diagnosis of an autistic spectrum disorder (ASD). Four case studies are described which address reductions in behaviours such as assaultive and destructive behaviour, out‐of‐seat behaviour, inappropriate contact with others and loud vocalisations, while also increasing the following of directions in the classroom and at playtimes. The common thread across all of the case studies is the use of the behaviour contract and the link that is built between home and school. The authors suggest that it is this contingent link that is the basis for the success in each of these studies. Based on their research, they believe that the behaviour contract can be considered an important and useful tool in helping address challenging behaviours in children with an ASD. Emma Hawkins is the Director of Education at The Jigsaw CABAS® School and oversees the implementation of strategies at the school to improve the behaviour of the pupils. Grant Gautreaux, from Nicholls State University in Louisiana, consults at The Jigsaw CABAS® School and is a member of the CABAS® Board. All of the remaining authors work at The Jigsaw CABAS® School and have successfully implemented the behaviour contract in their classrooms.  相似文献

A self-contained polymeric cartridge for automated biological sample preparation     

Xu G  Lee DY  Xie H  Chiew D  Hsieh TM  Ali EM  Lun Looi X  Li MH  Ying JY 《Biomicrofluidics》2011,5(3):34107-341079

Sample preparation is one of the most crucial processes for nucleic acids based disease diagnosis. Several steps are required for nucleic acids extraction, impurity washes, and DNA/RNA elution. Careful sample preparation is vital to the obtaining of reliable diagnosis, especially with low copies of pathogens and cells. This paper describes a low-cost, disposable lab cartridge for automatic sample preparation, which is capable of handling flexible sample volumes of 10 μl to 1 ml. This plastic cartridge contains all the necessary reagents for pathogen and cell lysis, DNA/RNA extraction, impurity washes, DNA/RNA elution and waste processing in a completely sealed cartridge. The entire sample preparation processes are automatically conducted within the cartridge on a desktop unit using a pneumatic fluid manipulation approach. Reagents transportation is achieved with a combination of push and pull forces (with compressed air and vacuum, respectively), which are connected to the pneumatic inlets at the bottom of the cartridge. These pneumatic forces are regulated by pinch valve manifold and two pneumatic syringe pumps within the desktop unit. The performance of this pneumatic reagent delivery method was examined. We have demonstrated the capability of the on-cartridge RNA extraction and cancer-specific gene amplification from 10 copies of MCF-7 breast cancer cells. The on-cartridge DNA recovery efficiency was 54-63%, which was comparable to or better than the conventional manual approach using silica spin column. The lab cartridge would be suitable for integration with lab-chip real-time polymerase chain reaction devices in providing a portable system for decentralized disease diagnosis.  相似文献   

Gender representation in Hong Kong primary school ELT textbooks – a comparative study     

Jackie F.K. Lee 《Gender and education》2014,26(4):356-376

This article seeks to investigate whether the improvement of the status of women in Hong Kong in recent decades, effected through various efforts to promote the values of equal opportunity concepts, is reflected in patterns of gender representation in primary school textbooks used in Hong Kong. A comparison of a popular series of primary school English-language textbooks that was published in 2005 with the same series published in 1988 (12 books in total) revealed increase in gender equity in the more recent books, including increased visibility of women both visually and textually. Nevertheless, the findings also revealed a perpetuation of some stereotyped images of the two genders and portrayals of women in a more limited range of social roles than men. The ‘male-first’ phenomenon and the visual and textual under-representation of women were still prevalent in the contemporary textbooks. The potential impacts on children of unbalanced gender representation in textbooks are discussed within the framework of social cognitive theory.  相似文献   

Who are the self‐publishers?     

Alison BAVERSTOCK  Jackie STEINITZ 《Learned Publishing》2013,26(3):211-223

This paper describes new research into the motivations, demographics, processes, and outcomes of self‐publishing authors of books. The findings challenge traditionally held notions about self‐publishing being a process undertaken by the untalented, as a last resort. The cohort studied emerges as highly educated, often well informed about the publishing process, and generally very positive about the self‐publishing experience. As the number of people self‐publishing continues to grow and associated technology progresses, a number of fundamental implications for stakeholders in both the non‐fiction and fiction publishing business pipelines are noted. With disintermediation now widespread, there will be increased pressure on the traditional industry to adapt its business models and focus on adding value. At the same time, opportunities in publishing services can be identified and the role of the author is significantly enhanced. Parallels between the cultures and processes of academic and self‐publishing authors are discussed; these will set the scene for future research.  相似文献

Models and messengers of resilience: a theoretical model of college students’ resilience,regulatory strategy use,and academic achievement     

Marcus L. Johnson  Gita Taasoobshirazi  Jessica L. Kestler  Jackie R. Cordova 《教育心理学》2015,35(7):869-885

We tested a theoretical model of college students’ ratings of messengers of resilience and models of resilience, students’ own perceived resilience, regulatory strategy use and achievement. A total of 116 undergraduates participated in this study. The results of a path analysis indicated that ratings of models of resilience had a direct effect on students’ perceived resilience and that perceived resilience directly influenced regulatory strategy use (i.e. effort regulation, self-regulation and time management), which influenced academic achievement (as measured by grade point average). The implications of our findings are further discussed, along with avenues for future research.  相似文献
