Five groups of undergraduate students, dropouts (academic dismissals), low (GPA) stopouts, high (GPA) stopouts, low (GPA) persisters, and high (GPA) persisters were compared in terms of their responses to a checklist of financial sources of support. Clear sex differences were observed in the reliance on financial sources, either singly or in terms of total sources utilized. Differences related to year in school were also observed. The most significant finding related to attrition was that persisters relied on more sources of support than did withdrawers. This outcome was interpreted in terms of differences between persisters and withdrawers in motivational and personality characteristics that promote the seeking and securing of sources of support. 相似文献

Seven computer applications to science assessment are reviewed. Conventional test administration includes record keeping, grading, and managing test banks. Multiple-choice testing involves forced selection of an answer from a menu, whereas constructed-response testing involves options for students to present their answers within a set standard deviation. Adaptive testing attempts to individualize the test to minimize the number of items and time needed to assess a student's knowledge. Figurai response testing assesses science proficiency in pictorial or graphic mode and requires the student to construct a mental image rather than selecting a response from a multiple choice menu. Simulations have been found useful for performance assessment on a large-scale basis in part because they make it possible to independently specify different aspects of a real experiment. An emerging approach to performance assessment is solution pathway analysis, which permits the analysis of the steps a student takes in solving a problem. Virtually all computer-based testing systems improve the quality and efficiency of record keeping and data analysis. 相似文献

This study investigated the effect of Pen-Point and Powerbook computers on solving a multiple step chemistry (molaritý) problem among White, Afro-American and Hispanic students (N=60) at the high school level. The screens on both computers were partitioned into a work field and a reasoning field. Both computers were programmed to record the time spent in each field, the number of entries made, and a copy of the entries made. Statistical analysis of data showed that more of the White and Afro-American Pen-Point computer users solved the problem correctly than did students using the Powerbook computer. All three ethnic groups made fewer entries, and took less time using the Pen-Point computer than the Powerbook. Attitude survey results of all ethnic groups showed that more Pen-Point computer users felt comfortable working with computers. Over all, the results suggest that the Pen-Point computer has a more positive effect on the problem solving performance and attitude of students towards computers than the Powerbook computer. 相似文献

Administrative growth and administrative expenditures are major issues for institutions of higher education. This paper reports
on a study of administrative costs and structures at lowa State University. Various indicators of administrative efficiency
are examined, including those related to administrative structures, administrative costs, administrative salaries, and administrative
intensity. For each of these aspects, the paper describes the methodology used, summarizes the findings, and provides comparisons
to peer institutions when these are available. Conclusions and plans, for the ongoing examination of administrative costs
and structures at lowa State University are presented. The final section discusses the adaptability of the methodologies used
in this study to studies that could be conducted by other institutions of higher education.

OBJECTIVE: This study examines the unique contribution of five types of maltreatment (sexual abuse, physical abuse, emotional abuse, physical neglect, emotional neglect) to adult health behaviors as well as the additive impact of exposure to different types of childhood maltreatment. METHOD: Two hundred and twenty-one women recruited from a VA primary care clinic completed questionnaires assessing exposure to childhood trauma and adult health behaviors. Regression models were used to test the relationship between childhood maltreatment and adult health behaviors. RESULTS: Sexual and physical abuse appear to predict a number of adverse outcomes; when other types of maltreatment are controlled, however, sexual abuse and physical abuse do not predict as many poor outcomes. In addition, sexual, physical, and emotional abuse and emotional neglect in childhood were all related to different adult health behaviors. The more types of childhood maltreatment participants were exposed to the more likely they were to have problems with substance use and risky sexual behaviors in adulthood. IMPLICATIONS: The results indicate that it is important to assess a broad maltreatment history rather than trying to relate specific types of abuse to particular adverse health behaviors or health outcomes. 相似文献

The project-grant mechanism is a major determinant of research styles and the direction and degree of scientific progress. Insofar as such research increasingly serves as the source of technology, and thus of economic, social and political change, the mechanism also influences, if only indirectly, the societal condition. In its current form the mechanism permits the support of significant amounts of research to be determined on the basis of scientific merit. The result has been the substitution of scientific progress for the achievement of tangible technical ends as the measure of public accountability. Given the increased appearance of undesirable social consequences based, in part, on scientific accomplishments this substitution is now seriously questioned. It has given rise to several attempts to make academic research more responsive to public needs while attempting to preserve the essentials of academic freedom. 相似文献
