This is the first of two articles outlining research into the understanding of the concepts of rational planning in secondary schools. The OFSTED Framework suggests that rational planning fosters school effectiveness and in earlier research the team found that this was broadly true. However, there are examples of schools which are criticised for their lack of rational planning but which are nevertheless successful in their outcomes. Four case study schools were selected for further investigation, two of these having been the subject of some critical comment from OFSTED. The investigation probed the relationship between leadership and effective planning and resource management in each of the schools. In the first article the importance of managing the relationship of the school with its environment in each of the four schools is considered. Understanding, moulding and living with the culture of the school appears to be of considerable importance to effective leadership. In these aspects of management heads appear to be working along a continuum which has a balance between systems organisation and an integrative culture. Our conclusion in the first article is that schools which are strongly rational in their approach to planning are also systems dominated, whilst those which are more pragmatic are likely to have a more open and integrative culture. However, all four schools are seen to be successful by their internal and external communities.  相似文献

This article examines the idiosyncratic development of Israel's communication field against the backdrop of the field's main structural dilemmas: (a) emphasis on research orientation versus on professional journalistic training and (b) firm boundaries for the field based on its mother disciplines (humanities or social sciences) versus open boundaries adopting different disciplines' research topics/methods that touch on communication phenomena. The article suggests a theoretical framework based on criteria anchored in the sociology of science and then applies these criteria to an analysis of the institutionalization and development of the Communication Institute at the Hebrew University of Jerusalem from its foundation in 1964 through the 1990s. The study is based on documents from the university archive and the Guttman Institute for Applied Social Research, curricula and catalogs of communication departments in Israel, and interviews with senior researchers in the field.  相似文献

This article reports the results of an analysis of 1676 science and technology questions submitted by Israeli children to a series of television programmes. It categorizes the children’s questions with reference to five different coding schemes: field of interest, motivation for asking the question, type of information requested, country‐specific aspects, and source of information. The results point to the popularity of biology, technology, and astrophysics over other sciences, indicate a shift in interests and motivation with age, and reflect a variety of gender‐related differences within the sample. The implications of the findings for some current trends in curriculum development and for informal science education are discussed with reference to the wider context of the pupils’ voice in education.  相似文献

This study, conducted in Israel, examined the social and emotional difficulties of gifted children, in comparison with nongifted children. The gifted children were further compared in two educational settings: segregated classes and pull-out programs. The 974 participants were from the fifth to twelfth grades. The dependent variables included loneliness, social competence, empathy, and self-concept. The results indicated that gifted children score higher on need fulfillment, empathy, academic self-concept, and lack of emotional anxiety and lower on self-disclosure and physical self-concept. Few differences were found between the two settings for gifted children. The conclusion is that gifted children differ from nongifted children only on some of the social–emotional variables examined, mainly for the better.  相似文献

Previous studies have shown that students often ignore molecular mechanisms when describing genetic phenomena. Specifically, students tend to directly link genes to their encoded traits, ignoring the role of proteins as mediators in this process. We tested the ability of 10th grade students to connect genes to traits through proteins, using concept maps and reasoning questions. The context of this study was a computational learning environment developed specifically to foster this ability. This environment presents proteins as the mechanism-mediating genetic phenomena. We found that students’ ability to connect genes, proteins, and traits, or to reason using this connection, was initially poor. However, significant improvement was obtained when using the learning environment. Our results suggest that visual representations of proteins’ functions in the context of a specific trait contributed to this improvement. One significant aspect of these results is the indication that 10th graders are capable of accurately describing genetic phenomena and their underlying mechanisms, a task that has been shown to raise difficulties, even in higher grades of high school.  相似文献

目的:探讨荧光定量PCR检测HBV DNA与HBVm的关系。方法;采用荧光定量PCR法和酶联免疫吸附试验(ELISA)对159份HBVm8种不同阳性模式及67份HBVm全阴模式血清进行HBV DNA检测。结果;HBsAg、HBcAb、HBeAe阳性者HBV DNA阳性率为89.83%;HBsAg、HBcAb、HBeAb阳性者HBV DNA阳性率为28.81%;HBsAb、HBcAb、HBeAb阳性者HBV DNA阳性率为16.66%;HBVm全阴性者HBV DNA阳性率为17.91%。结论:荧光定量PCR法检测HBV DNA是乙型肝炎病毒复制最直接可信的指标.可反映HBV真实感染和复制状态.特别是低复制状态,明显优于ELISA法检测HBVm,具有重要临床意义。  相似文献
