Face-to-face contact in blended learning for intercultural education: the role of teachers     

Roger Austin  Angela Rickard  Jacqueline Reilly 《Irish Educational Studies》2017,36(3):323-340

In societies experiencing or emerging from conflict, teachers often deliver educational programmes designed to build community cohesion. We report on research which examined teachers’ views of the implementation of a programme involving both face-to-face and online contact between pupils. Findings suggest that this blended approach is highly motivational, enhancing online work and relationship building. The research underlines the importance of the political, educational and historical context for work of this sort and the impact this has on the particular blend of online and face-to-face interaction. Implications for policymakers and teachers include value for money and sustainability of blended intercultural education in similar contexts.  相似文献   

Effects of ABRACADABRA Instruction on Spelling in Children With Autism Spectrum Disorder     

Benjamin Bailey  Roger J. Stancliffe 《Scientific Studies of Reading》2017,21(2):146-164

This study explored the effects of an evidence-based literacy program, ABRACADABRA, on the spelling abilities of children with autism spectrum disorder (ASD). Twenty children with ASD aged 5–11 years were assigned to matched instruction and waitlist control groups. Children in the instruction group received 26 hrs of individualized, home-based instruction using ABRACADABRA over a 13-week period. Results showed no change in children’s conventional spelling accuracy skills following ABRACADABRA instruction. However, an analysis of spelling attempts using the Computerized Spelling Sensitivity System (Masterson & Hrbec, 2011) revealed statistically significant gains in linguistic spelling accuracy for children in the instruction group relative to the waitlist control group, with large effect sizes. These findings suggest that ABRACADABRA improves aspects of spelling ability in children with ASD and that the Computerized Spelling Sensitivity System is a useful tool for detecting changes in the spelling abilities of children with ASD following literacy instruction.  相似文献

Head injury secondary to suspected child maltreatment: results of a prospective Canadian national surveillance program     

Bennett S  Ward M  Moreau K  Fortin G  King J  Mackay M  Plint A 《Child abuse & neglect》2011,35(11):930-936

Objective

We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.

Methods

From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.

Results

There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.

Conclusion

This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system.  相似文献   

Formative assessment of procedural skills: students’ responses to the Objective Structured Clinical Examination and the Integrated Performance Procedural Instrument     

Debra Nestel  Roger Kneebone  Carmel Nolan  Kash Akhtar  Ara Darzi 《Assessment & Evaluation in Higher Education》2011,36(2):171-183

Assessment of clinical skills is a critical element of undergraduate medical education. We compare a traditional approach to procedural skills assessment – the Objective Structured Clinical Examination (OSCE) with the Integrated Performance Procedural Instrument (IPPI). In both approaches, students work through ‘stations’ or ‘scenarios’ undertaking defined tasks. In the IPPI, all tasks are contextualised, requiring students to integrate technical, communication and other professional skills. The aim of this study was to explore students’ responses to these two assessments. Third‐year medical students participated in formative OSCE and IPPI sessions on consecutive days. Although performance data were collected in both assessments, quantitative data are not presented here. Group interviews with students were conducted by independent researchers. Data were analysed thematically. The OSCE and the IPPI were both valued, but for different reasons. Preference for the OSCE reflected the format of the summative assessment. The IPPI was valued for the opportunity to practise patient‐centred care in a simulated setting which integrated technical, communication and other professional skills. We posit that scenario‐based assessments such as the IPPI reflect real‐world issues of patient‐centred care. Although the limitations of this study prevent wide extrapolation, we encourage curriculum developers to consider the influence of assessments on what and how their students learn.  相似文献   

Face-to-face versus computer-mediated discussion of teaching cases: Impacts on preservice teachers’ engagement, critical analyses, and self-efficacy     

Lisa M. PytlikZillig  Christy A. Horn  Roger Bruning  Stephanie Bell  Xiongyi Liu  Kamau O. Siwatu  Mary C. Bodvarsson  Doyoung Kim  Deborah Carlson 《Contemporary educational psychology》2011,36(4):302-312

Two frequently-used discussion protocols were investigated as part of a program to implement teaching cases in undergraduate educational psychology classes designed for preservice teachers. One protocol involved synchronous face-to-face (FTF) discussion of teaching cases, which occurred in class after students had individually completed written case analyses as homework outside of class. The other was asynchronous computer-mediated (CM) discussion taking place outside of class, simultaneous to students’ completion of their written case analyses. Six class offerings of an undergraduate child development course taught by two instructors (three classes by each instructor) were randomly assigned within instructor in a quasi-experimental design to one of the three discussion conditions: FTF, CM, or no discussion of the cases across the semester. Findings indicated that both CM and FTF discussion conditions were associated with positive outcomes relative to the control condition. Both CM and FTF discussion related to higher cognitive–affective engagement with the cases than the control condition; and the CM discussion condition was associated with higher cognitive–affective engagement than FTF discussion. In contrast, FTF discussion, but not CM discussion, was associated with higher-than-control-condition case analysis ability at the end of the semester. Potential explanations for these findings and directions for future research are discussed.  相似文献   

Integrated carbon fiber electrodes within hollow polymer microneedles for transdermal electrochemical sensing     

Miller PR  Gittard SD  Edwards TL  Lopez DM  Xiao X  Wheeler DR  Monteiro-Riviere NA  Brozik SM  Polsky R  Narayan RJ 《Biomicrofluidics》2011,5(1):13415

In this study, carbon fiber electrodes were incorporated within a hollow microneedle array, which was fabricated using a digital micromirror device-based stereolithography instrument. Cell proliferation on the acrylate-based polymer used in microneedle fabrication was examined with human dermal fibroblasts and neonatal human epidermal keratinocytes. Studies involving full-thickness cadaveric porcine skin and trypan blue dye demonstrated that the hollow microneedles remained intact after puncturing the outermost layer of cadaveric porcine skin. The carbon fibers underwent chemical modification in order to enable detection of hydrogen peroxide and ascorbic acid; electrochemical measurements were demonstrated using integrated electrode-hollow microneedle devices.  相似文献
