Expectations versus reality: the case of Liberal Studies in Hong Kong’s new senior secondary reforms     

Dennis Fung 《Compare》2016,46(4):624-644

This article reports the findings of a five-year longitudinal study investigating the introduction of Liberal Studies in the context of Hong Kong’s new senior secondary educational reforms. The aim of this empirical research, which adopted diachronic analysis to allow comparisons over time, was to compare teachers’ and students’ perceptions of the Liberal Studies curriculum before and after its introduction. Methodologically speaking, the study was informed by documentary inquiry, with approximately 560 newspaper articles and government reports collected to identify the issues surrounding the curriculum debate. Questionnaire-based surveys conducted in the pre- and post-reform periods revealed a sharp contrast between expectations and reality for both participant groups following the curriculum’s introduction. Whilst the students demonstrated favourable attitudes towards Liberal Studies before studying the subject, a certain degree of disappointment was expressed after the new curriculum came into effect. In follow-up interviews with teachers, they expressed a lack of confidence in teaching such a multi-disciplinary subject and criticised the overly ambitious nature of the curriculum. Liberal Studies, as currently taught, runs the risk of falling out of favour with Hong Kong secondary school teachers, and the question of whether it will play an increasingly important role in promoting patriotic education after the demise of Moral and National Education is deserving of research attention.  相似文献

Connecting Video Segments to Collaborative Learning Activities     

Dennis Adams 《Educational Media International》2013,50(3):158-163

Abstract

The article discusses how sections of a video can best be used in the instructional process by activating the minds of students and using their reactions to viewing to produce intellectual action. It gives some suggested schemes for this activity and shows how technological forces can become energies of change.  相似文献   

The Impact of Tier 2 Mathematics Instruction on Second Graders with Mathematics Difficulties     

Minyi Shih Dennis  Robin Drogan 《Exceptionality》2013,21(2):124-145

Although research on Tier 2 interventions for early mathematics is accumulating, such efforts remain far behind those for reading, especially regarding specific features such as the ideal time to begin an intervention. The present study investigated the effectiveness of a Tier 2 intervention using a single subject multiple baseline, across-groups design with two cohorts of second graders. Because the two cohorts of students were given the intervention at different times during the second grade year, the study also documented whether the timing of the intervention affected acquisition and retention of second grade mathematics competencies. Finally, the study tracked student performance up to the first semester of the third grade year to document any sustained effects. The results show that the supplemental intervention was effective for both cohorts, but differences in performance indicate that the timing of the intervention may affect the degree of success. In addition, for some participants, the positive effects of the intervention were sustained into the third grade year.  相似文献   

Herceptin functionalized microfluidic polydimethylsiloxane devices for the capture of human epidermal growth factor receptor 2 positive circulating breast cancer cells     

Thierry B  Kurkuri M  Shi JY  Lwin LE  Palms D 《Biomicrofluidics》2010,4(3):32205

Building on recent breakthroughs in the field of microfluidic-based capture of rare cancer cells circulating in the blood, the present article reports on the use of Herceptin functionalized PDMS devices designed to efficiently capture from blood cancer cells, overexpressing the tyrosine kinase human epidermal growth factor receptor (HER2). The identification of patients overexpressing HER2 is critical as it typically associates with an aggressive disease course in breast cancer and poor prognosis. Importantly, HER2 positive patients have been found to significantly benefit from Herceptin (Trastuzumab), a humanized monoclonal antibody (MAb) against HER2. Disposable PDMS devices prepared using standard soft lithography were functionalized by the plasma polymerization of an epoxy-containing monomer. The epoxy-rich thin film (AGEpp) thus created could be conjugated with Herceptin either directly or through a polyethylene glycol interlayer. The properties and reactivity toward the monoclonal antibody conjugation of these coatings were determined using x-ray photoelectron spectroscopy; direct conjugation provided a good compromise in reactivity and resistance to biologically nonspecific fouling and was selected. Using the breast cancer cell line SK-BR-3 as a model for cells overexpressing HER2, the immunocapture efficacy of the Herceptin functionalized PDMS was demonstrated in model studies. Validation studies confirmed the ability of the device to efficiently capture (～80% capture yield) HER2 positive cells from full blood.  相似文献

Regression Analysis for Prediction: Understanding the Process     

Phillip B Palmer  Dennis G O'Connell 《Cardiopulmonary Physical Therapy Journal》2009,20(3):23-26

Research related to cardiorespiratory fitness often uses regression analysis in order to predict cardiorespiratory status or future outcomes. Reading these studies can be tedious and difficult unless the reader has a thorough understanding of the processes used in the analysis. This feature seeks to “simplify” the process of regression analysis for prediction in order to help readers understand this type of study more easily. Examples of the use of this statistical technique are provided in order to facilitate better understanding.  相似文献
