The purpose of this study was to determine and analyze the annual cost of operation including depreciation of movable capital equipment for educating one student in each curriculum of selected community colleges and to show the relationship of costs of vocational-technical curricula to the cost for common baccalaureate oriented curricula.A stratified sample of eight community colleges was drawn from those that had been in operation for at least five years.These data indicate that a majority of the courses offered in highly specialized curricula in both the occupational and baccalaureate categories were more expansive than those courses that were common to a wide variety of curricula.This study supports differential program funding to assure continued development of high quality vocational-technical programs in community colleges.  相似文献

OBJECTIVE: The present study evaluated the association between women's health and physical and sexual abuse suffered before age 18. METHODS: A total of 3,568 randomly sampled insured women ages 18-64 completed a telephone interview to assess history of physical only, sexual only, or both physical and sexual abuse before age 18 (Behavioral Risk Factor Surveillance System); and current health (Short Form-36, Center for Epidemiologic Studies-Depression, Presence of Symptoms surveys). Adjusted analyses compared the health of women with physical abuse only, sexual abuse only, or physical and sexual abuse to the health of women without these abuse histories. RESULTS: Poorest health status was observed in women with a history of both physical and sexual child abuse compared to women without these abuse histories. In models that adjusted for age and income, women with both abuse types had increased prevalence of depression (prevalence ratio, 2.16), severe depression (PR, 2.84), physical symptoms (PR range, 1.33 for joint pain to 2.78 for nausea/vomiting), fair/poor health (PR, 1.84), and lower SF-36 scores (3.15-5.40 points lower). Women with physical abuse only or sexual abuse only also had higher prevalence of symptoms and lower SF-36 scores but the associations were not as strong. CONCLUSIONS: This study adds to the literature showing a graded association between multiple adverse events in childhood and adult health.  相似文献

Workplace stress has received a fair amount of treatment in the research literature over the past decade. What has not been examined, at least not systematically, is this same phenomena inacademe. Our study looked at stress among university faculty at a land-grant university located in the western region of the U. S. Analyses from the self-assessment mail survey (N = 786) reveals that faculty in the Hard Pure Nonlife (e. g., Astronomy, Math, Physics), Hard Applied Nonlife (e. g., Civil Engineering, Nuclear Engineering, Computer Science) and Soft Applied Life (e. g., Education Administration, Special Education) experience more stress than faculty in disciplines such as Hard Pure Life (e. g., Botany, Zoology) and Soft Pure Nonlife (e. g., English, Philosophy, Communications). Careful attention was paid to the different levels of stress reported by male and female faculty, with women professors reporting a higher level of stress than their male counterparts. We provide an assessment and explanation for this finding. Research ends with several proposals for individual faculty, department chairs and academic administrators for addressing the problem of workplace pressure and work overload.  相似文献

Increasing interest in science education research has focused on ways of representing cognitive structure in graphical and quantitative terms. A method is presented for displaying the sequential and multirelational ideation of scientific narrative elicited from respondents. The flow map provides a figural representation of the flow of information, the points in the flow where multirelational and recurrent linkages are made, and the time required to retrieve and express the information at major intervals in the sequence and in total. In keeping with constructivist models of information analysis, the elicitation of responses requires minimal intervention by the interviewer, and flow-map representation requires low inference for its construction, providing a convenient diagram of the sequential and multirelational thought patterns expressed by the respondent. The method is illustrated by analyzing interviews from students varying in academic achievement under two interview conditions that varied in emphasis on recall of multiple relationships. The illustrative data show that students of increasing academic ability produce flow maps of more complex patterns with more cross-relational linkages. These kinds of linkages, on the whole, increase with increased emphasis in the interview on recall of relationships.  相似文献

The use of teaching strategies associated with a conceptual change model of science teaching was examined in a study of thirteen 7th-grade life science teachers. Teachers taught units on photosynthesis, cellular respiration, and matter cycling in ecosystems in their regular classes under conditions varying as to whether or not conceptual change-oriented instructional materials and training sessions were provided. Greater use of conceptual change teaching strategies was associated with use of the special instructional materials, but not with the training. Students in classes where teachers were provided with the materials tended to perform better on posttests than those where such materials were not provided. The use of the conceptual change strategies by teachers was also associated with higher student performance on tests designed to assess conceptual change learning. The results support claims for the usefulness of conceptual change teaching strategies, but few of the teachers in this study could successfully implement these strategies without the support of appropriately designed curriculum materials.  相似文献

This study explored the beliefs about student engagement in mathematics of three Year 5 and 6 teachers, focusing on the shifts that occurred during a 10-week intervention. Data obtained from teacher surveys, interviews, video-recorded workshop observations and artefacts from teachers’ classrooms reveal variations in their reactions to the professional learning experiences. Teacher responses were mediated by personal and contextual elements including teacher efficacy beliefs, teacher confidence in mathematics and their conceptions of student engagement. Theories of teacher conceptual change are used to account for variations to teacher beliefs.  相似文献
