Abstract This paper reports an experimental evaluation of a direct instruction procedure in which children are taught and practise activities to both foster and monitor their comprehension while reading. Three different class groups of low comprehenders, Standard 4, Form 1 and Form 2, were serially exposed to 21 days of 20‐25 minutes instruction in four study activities: summarising, questioning, clarifying and predicting. Instruction was by reciprocal teaching whereby the adult tutor and children took turns leading a dialogue centred around the important topics of the instructional text. The design of this study incorporated both with‐subjects multiple baseline and between‐subjects comparisons, the no treatment comparison groups being average and above average comprehending class peers. Daily comprehension assessment on a different text at the same difficulty level as that used for reciprocal teaching and pre and post intervention scores on a reading comprehension test served as the dependent measures for the study. Results show significant increases in accuracy on comprehension tests for all experimental groups upon introduction of the reciprocal teaching procedure. On completion of the intervention two of these groups scores matched those of the above average controls. Follow‐up probes eight weeks later showed that all groups had maintained their comprehension gains. 相似文献

16PF Personality profiles for 364 young civil engineers have been compared to the British Norms for the 16PF Questionnaire. Civil Engineers differ from the British Norms on five of the 20 factors derived from the Questionnaire. These factors indicate the questions on which to concentrate when selecting students for civil engineering courses. 相似文献

The possibility of using diagnostic tests was explored and several tests were used with civil engineering students to see if they would be useful in selecting students for the civil engineering degree course. The performance of students on the tests used was compared with the examination results and it was found that the tests showed a little promise. It will be necessary to design a test specifically for civil engineering students. On the other hand perhaps our methods of teaching and examining subjects fundamental to civil engineering should be examined in depth. The results from the tests used indicated a culture gap between home and overseas students and the need for a database of student information. 相似文献

Results that bear upon the psychometric properties of the Quality of Life Instrument Package are presented. The reliability and validity of quality of life data from a probability sample of 500 persons with developmental disabilities in Ontario were assessed. The data indicate that most of the instruments found in the package met acceptable psychometric standards. In some cases, specific domain scores need to be interpreted with caution. The Full Version of the instrument seems appropriate for ongoing practical program planning with clients. The Short Version seems especially appropriate for evaluation and monitoring purposes. 相似文献

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
