This article examines the impact of a two-year multimedia computer-based program of structured learning and assessment introduced into fifteen primary schools in three London boroughs. The project was evaluated and the results are reported here. The evaluation had two purposes: to explore the actual effects of the programs during the time span of the project, and to understand the contexts in which they operated.  相似文献

OBJECTIVE: This study investigated the relationship of interrupted memories of childhood abuse with the secrecy of the abuse. METHODOLOGY: Fifteen hundred people were randomly selected from the membership of the American Counseling Association and sent a questionnaire regarding childhood abuse history. Four hundred and twenty-three usable questionnaires were returned and analyzed. RESULTS: Thirty-two percent of the sample reported childhood abuse. Fifty-two percent of those reporting abuse also noted periods of forgetting some or all of the abuse. On the two survey items assessing secrecy, 76% of respondents reporting childhood abuse indicated there had been a time when no one but themselves and their abuser knew about the abuse; 47% indicated that an abuser tried to get them to keep the abuse secret. Forty percent endorsed both secrecy items. Respondents who reported forgetting abuse also reported one or both elements of secrecy more frequently than those who reported continuous memories of abuse. CONCLUSION: These findings are consistent with those of other studies that suggest that, among adults reporting childhood abuse, the experience of forgetting some or all abuse is common. Secrecy of the abuse appears to be associated with the experience of forgetting childhood abuse for many individuals.  相似文献

A number of questions are raised concerning the purposes of data coding in qualitative research. It is suggested that in some cases these purposes may usefully be organised into two broad categories, each of which requires a separate coding response. A research project is briefly described in which it was found useful to employ two distinct, though connected, phases of data coding along the lines proposed.  相似文献

Higher education's efforts to respond to the growing demand for non-traditional programs and services have resulted in the proliferation of external degree programs. The present inquiry examines the status of these programs in traditional institutions. Basing evaluation on the guidelines set forth by the Carnegie Commission for Non-Traditional Study (1973), the author suggests that external programs have not achieved the desired degrees of integration into the academic mainstream. Diverse management and planning approaches that might facilitate institutional adaptation and enhance program strength and viability are explored.  相似文献

Prediction of the enrollment effects of institutional closure   总被引:1,自引:1,他引:0  
The expected decline in the number of high school graduates in the United States through the rest of this decade will almost certainly lead to closure of some higher education institutions. An important part of the analysis of the expected effects of institutional closure is estimation of redistribution of students attending the closed school. This paper shows how coefficient estimates from models of enrollment demand can be used to predict the alternative attendance choices of students enrolled at the closed school. The results indicate that predictions differ depending on the estimation method used and that the predictions using some methods are sensitive to subjective assumptions.  相似文献
