In pursuit of teacher quality in diversity: A study of the selection mechanisms of new secondary teacher education programmes in Taiwan 总被引:1,自引:0,他引:1
As the definition of teacher quality changes with time, the selection mechanism of students into teacher education programmes may also change accordingly. In Taiwan, before the 1994 teacher education reform, selection of pre-service students was based solely on academic achievement. Afterwards, the selection was delegated to individual teacher education programmes with varied missions for teacher education. This study examines the degree of diversity and selectivity of the selection mechanisms of these programmes. Data from 48 programmes, including institutional documents, telephone inquiries and governmental reports, were collected and analysed. The results show that the selection mechanisms of these programmes are diverse enough to reflect a variety of characteristics of teacher quality, and rigorous enough to ensure a certain level of quality. Related issues on teacher selection are further discussed. 相似文献

AbstractThe paper examines participant perceptions of the effectiveness of using case studies with college students (undergraduate – doctoral) to teach social justice and educational equity. Findings indicate that participants who identified with the characters in the cases were able to draw connections between the case and their own personal experiences. They felt the cases broadened their understanding of the topics and increased their sense of empathy and their commitment to principles of social justice. 相似文献

To advance the discussion on the validity of student evaluations of university teaching, student ratings of two teaching dimensions – student involvement and rapport – were compared with corresponding observer ratings. Seven potential bias variables were tested with regard to their impact on the students’ teaching assessment: three teacher characteristics (first impression, enthusiasm, humour) and four student characteristics (prior interest, expected grades, study experience, class attendance). Bias was defined as an impediment of the students’ assessment of teaching on course level. By means of bivariate correlations with course averages and two-level latent moderated structural equations, data of 1,716 students in 80 courses were analysed. Results showed that all three teacher characteristics were genuinely connected to rapport, and even explained variance of the student-rated variable when controlling for observer-rated rapport. The assessment of student involvement was not modified by the teacher characteristics except for teacher enthusiasm, which affected the student evaluation when controlling for observed involvement and, moreover, moderated the relation between the observed and the student-rated variable. For the examined student characteristics, no biasing effects were found – neither on rapport nor on student involvement. 相似文献

教育男生和女生:对性别平等教育的启示 总被引:2,自引:0,他引:2
性别平等教育长期被视作教育中的次要问题,教育学界对此也存在不少误解。“零和式”的教育使性别平等问题走向了极端。性别平等教育的目标不仅使女生享有平等的教育的机会,同时也使男生受益。打破教育体制中固有的性别成见才是实现平等教育的根本途径。 相似文献

鉴定结论作为一种民事证据方法越来越受到人们的重视。鉴定结论是否科学与鉴定人密切相关。我国立法中设立了鉴定人制度。但在实践中,我国鉴定人制度存在着诸多的不足。通过对存在的缺陷做一浅要分析,在鉴定主体、鉴定人选任模式、鉴定人权利义务和适用规则等方面提出建议,以完善我国的鉴定人制度。 相似文献
