Conclusion Supervision, the most prevalent of the control mechanisms studied, was used in all of the schools to varying degrees. The frequency of superintendent visits fluctuated between a high of almost every day, in the case where the superintendent and the principal shared the same facility, to two times a year. Superintendents did visit schools without formal sessions with the principals. Several principals described their superintendents' visits as informal walk-throughs. District size did not influence the frequency of supervision by the superintendents. Schools in both large and small districts received roughly the same number of visits. Ninety-two percent of the principals received a medium or high number of visits. In some schools, particularly unit districts composed of grades kindergarten through 12, principals were evaluated by associate superintendents for secondary education. Central office personnel usually visited several times each month. Principals from large districts received fewer visits from central office staff than did principals from medium or small districts. Most principals perceived the visits by their superintendents and central office personnel as nonthreatening. When superintendents and central office administrators visited schools, they added to the system of control by collecting information about all aspects of schooling, including the climate. In general, principals perceived supervision as light, and felt that schools and principals were afforded considerable autonomy.Vanderbilt University 相似文献

Textbook vetting and evaluation process intends to ensure that the materials provided are relevant, of the required quality, suitable ad would enhance learning efficiency and effectiveness. The paper investigates the role of publishers and Tanzania Institute of Education (TIE) in the textbooks vetting and evaluation process; examines factors used to vet, evaluate and approve primary and secondary school textbooks in Tanzania and proposes Strategies that would enhance the textbook vetting, evaluation and process. The study used a mixed method research design. Respondents were selected educational publishers; MoEVT, Baraza la Kiswahili Tanzania, TIE, and Publishers Association of Tanzania. Questionnaire and semi- structured interview were used to collect data which were analysed qualitatively and quantitatively. Major findings of the study were; textbooks vetting and evaluation process is not professionally conducted although standard criteria have been established; there is not well established roles among key players involved in the vetting and evaluation process leading to conflict of interest between TIE and the publishers. The study recommends establishing an independent professional evaluation board and a well-defined timetable and effective communication among various players; enacting a book policy and adopting a limited multiple-textbook publishing system. 相似文献

Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness. 相似文献
