DNA capture-probe based separation of double-stranded polymerase chain reaction amplification products in poly(dimethylsiloxane) microfluidic channels     

Dmitriy Khodakov  Leigh Thredgold  Claire E. Lenehan  Gunther G. Andersson  Hilton Kobus  Amanda V. Ellis 《Biomicrofluidics》2012,6(2)

Herein, we describe the development of a novel primer system that allows for the capture of double-stranded polymerase chain reaction (PCR) amplification products onto a microfluidic channel without any preliminary purification stages. We show that specially designed PCR primers consisting of the main primer sequence and an additional “tag sequence” linked through a poly(ethylene glycol) molecule can be used to generate ds-PCR amplification products tailed with ss-oligonucleotides of two forensically relevant genes (amelogenin and human c-fms (macrophage colony-stimulating factor) proto-oncogene for the CSF-1 receptor (CSF1PO). Furthermore, with a view to enriching and eluting the ds-PCR products of amplification on a capillary electrophoretic-based microfluidic device we describe the capture of the target ds-PCR products onto poly(dimethylsiloxane) microchannels modified with ss-oligonucleotide capture probes.  相似文献   

Diversity and Mentoring in the Workplace: A Conversation with Belle Rose Ragins     

Dawn E. Chandler  Rebecca Ellis 《Mentoring & Tutoring: Partnership in Learning》2013,21(4):483-500

Given projected increases in workplace diversity, an understanding of diversity’s intersection with mentoring is a critical topic in the literature. This article involved an interview with Belle Rose Ragins, one of the world’s leading thinkers on diversity and mentoring in the workplace. After providing an overview of Ragins’ key achievements and contributions to the mentoring literature, the article delved into the interview, which involves four parts: (a) Ragins’ education and early influences; (b) her views on the extant literature as well as insights around future areas for inquiry; (c) her current research interests; and (d) her views on consulting and teaching.  相似文献   

Negotiating contrad(ICT)ions: teachers and students making multimedia in the secondary school     

Viv Ellis  Steve Long 《Technology, Pedagogy and Education》2013,22(1):11-27

Abstract

In this article, we investigate the use of multimedia information and communication technologies (ICTs) in integrated arts projects in two secondary schools. The ways in which teachers and students make sense of the technologies in relation to the dominant discourses of education/technology policy and educational research are explored before considering the implications for curriculum and teacher development. The ICT in the word contrad(ICT)ions is emphasised to represent the ways in which teachers and students' use of multimedia exposes and makes visible problematic issues in relation to literacy, school subjects and pedagogy.  相似文献   

Successful Community College Transfer Students Speak Out     

Martha M. Ellis 《Community College Journal of Research & Practice》2013,37(2):73-84

The community college as the entranceway into the baccalaureate degree is becoming a prevalent choice for students. This study was a qualitative approach to understanding attitudes, behaviors, and knowledge acquisition by successful community college transfer students. University students who transferred from a community college and were making successful progress toward completing the baccalaureate degree participated in focus groups to answer questions about the transfer process. Successful transfer students are highly motivated, persistent, engaged, believe they were well prepared by the community colleges for university junior level studies, and have recommendations for community colleges and universities in improving the transfer process.  相似文献

Students’ approaches to groupwork in a blended course,associations with perceptions of the online environment and academic achievement – when is learning engaged?     

Robert A. Ellis 《Education and Information Technologies》2016,21(5):1095-1112

University teachers provided first year Arts students with hundreds of cinematic images online to analyse as a key part of their predominantly face-to-face undergraduate course. This qualitative study investigates the extent to which the groups engaged in learning involving their analysis of the images and how this was related to their perception of the ICT-mediated environment. Interviews and questionnaires completed by students revealed that the extent of engaged learning was related to the quality of the approach to groupwork reported by the students, the quality of their approach to the analysis of the images and their perceptions of key aspects of the online environment which provided the images. The findings have implications for the design and approach to teaching best suited for students involved in groupwork and the use of ICT resources provided to promote engaged experiences of learning.  相似文献

A Simple Model to Determine the Efficient Duration of Exams     

Jules L. Ellis 《Educational and psychological measurement》2021,81(3):549

This study develops a theoretical model for the costs of an exam as a function of its duration. Two kind of costs are distinguished: (1) the costs of measurement errors and (2) the costs of the measurement. Both costs are expressed in time of the student. Based on a classical test theory model, enriched with assumptions on the context, the costs of the exam can be expressed as a function of various parameters, including the duration of the exam. It is shown that these costs can be minimized in time. Applied in a real example with reliability .80, the outcome is that the optimal exam time would be much shorter and would have reliability .675. The consequences of the model are investigated and discussed. One of the consequences is that optimal exam duration depends on the study load of the course, all other things being equal. It is argued that it is worthwhile to investigate empirically how much time students spend on preparing for resits. Six variants of the model are distinguished, which differ in their weights of the errors and in the way grades affect how much time students study for the resit.  相似文献   

Electronic Course Surveys: Does automating feedback and reporting give better results?     

Stuart Watt  Claire Simpson  Chris McKillop  Viv Nunn 《Assessment & Evaluation in Higher Education》2002,27(4):325-337

This paper discusses an electronic course survey system designed to support evaluation of a modular programme in management taught through distance education. The scale and communication issues raised by distance education, when compounded by a complex rolling modular programme, make conventional evaluation complicated, slow and expensive. To overcome these problems, an automated evaluation process was introduced, partly based on web-based surveying, but significantly emphasising the reporting process and allowing performance indicators and complex analyses to be embedded in high quality word-processed reports, that can be quickly and easily generated after each presentation of a module. The paper discusses the system and the impact that it has had on the evaluation process, before looking to future opportunities for developments in this field, and discussing some of the implications - both expected and unanticipated - that have come out of using automation in the evaluation process.  相似文献
