Ann Lewis 《教育心理学》1982,2(2):121-135
A Direct Instruction approach to remedial reading (Corrective Reading Programme) was evaluated in an urban Comprehensive school over two school years. First year remedial readers were randomly allocated to one experimental and two control groups. Groups were matched for sex. A similar procedure was followed in the second study carried out with the following group of first year remedial readers.

In the first three months of the first study all groups were monitored while receiving the school's usual remedial reading programme. They made comparable gains during this baseline period. Covariance analysis indicated that in the first study the experimental group and control group I (a ‘novelty’ programme) made significantly greater gains, in accuracy and comprehension, than control group 2 (the usual remedial reading programme). Findings from the second study confirmed the suggestion that gains for the experimental group in the first study were partly due to ‘novelty’ effects. Both experimental groups developed better strategies for tackling oral reading tasks (as assessed by miscue analysis) than control groups, however.  相似文献

OBJECTIVES: Funded by Research in the Workplace Award (RIWA) 2001, the study investigated the information needs and use of NHS library services by members of the West of Scotland Colorectal Cancer Managed Clinical Network (MCN), a single subject, cross boundary, multi-professional organization. METHOD: A postal questionnaire sent out in October 2002 was returned by 100 members and follow-up interviews were held in March 2003 with 11 of the respondents. The questions related to access to resources, library services such as literature searches, current awareness and training. They also explored the use of electronic resources and the Internet. RESULTS: Respondents were mainly hospital doctors and a few nurses from across five health boards. Most had access to a library, although not all made use of it, possibly an indication of the need for improved communications between librarians and health-care staff. Generally, research and professional development were reported as reasons for needing cancer information, but on further investigation the motivation to conduct literature searches was more related to patient care. Examples included treatment of unusual cases, locating information for patients and identifying guidelines. There are indications of unmet needs for local contact information and evaluated patient information. CONCLUSION: Development of a cancer portal within the NHS Scotland e-Library available from May 2004 based on the Managed Knowledge Network (MKN) concept is attempting to address many of the issues raised in the survey, including inequities of access to services and signposting to a variety of types of information.  相似文献

Visual representations are used to convey ideas and concepts. They add value to educational venues. Files digitized from hard-copy media or born-digital files are standard formats, and the Internet is a resource for locating billions of these files. Searchers should be cognizant of the legal and ethical implications of using images downloaded from the Internet. This article intends to inform users about medical images on the Internet, as well as providing a select list of Web-based medical image sources.  相似文献
