ABSTRACTIn research on teacher induction, scholars have pointed at the pivotal role of collegial support to overcome the challenges inherent to the first years of teaching. In this quantitative study, we extend current work by using a social network perspective to examine characteristics (i.e. network size, frequency and perceived usefulness) of professional, emotional, and social collegial support networks. Moreover, we explore the extent to which these characteristics explain key factors affecting teacher retention, namely job satisfaction, intrinsic motivation to teach, and self-efficacy. An online survey was completed by 292 beginning primary school teachers in Flanders (Belgium). Social network data showed that, on average, they receive professional, emotional and social support from six colleagues each week and found this mostly useful. Regression analyses demonstrated that network size and perceived usefulness of professional, emotional, and social collegial support networks were positively related to job satisfaction and intrinsic motivation to teach, thus confirming the importance of collegial support in teacher induction. Frequency of support was not significant. Finally, no substantial relationship was found between collegial support and teachers’ self-efficacy. Implications of these findings for practice and policy are discussed. 相似文献
The 2004 recipient of NCA's Gerald M. Phillips Award for Distinguish Applied Scholarship, Brent Ruben's professional record spans more than three decades and has focused in four major areas: organizational development, communication/information systems, medical/health communication, and intercultural communication. His publication record and professional presentations are extensive. His work with the Center for Organizational Development and Leadership at Rutgers is especially noteworthy and serves as an example of his best applied work. The reviewers were especially impressed with his most recent book, entitled Pursuing Excellence in Higher Education. His use of Baldrige-based criteria by which to measure excellence is a fine example of applying well-tested standards to the field of higher education. His work represents some of the best in the field of applied communication. 相似文献
Technological innovation requires the laboratories to ensure that modifications or incorporations of new techniques do not alter the quality of their results. In an ISO 15189 accredited laboratory, flexible scope accreditation facilitates the inclusion of these changes prior to accreditation body evaluation. A strategy to perform the validation of a biochemistry analyzer in an accredited laboratory having a flexible scope is shown.
Materials and methods:
A validation procedure including the evaluation of imprecision and bias of two Dimension Vista analysers 1500 was conducted. Comparability of patient results between one of them and the lately replaced Dimension RxL Max was evaluated. All studies followed the respective Clinical and Laboratory Standards Institute (CLSI) protocols. 30 chemistry assays were studied. Coefficients of variation, percent bias and total error were calculated for all tests and biological variation was considered as acceptance criteria. Quality control material and patient samples were used as test materials. Interchangeability of the results was established by processing forty patients’ samples in both devices.
Results:
27 of the 30 studied parameters met allowable performance criteria. Sodium, chloride and magnesium did not fulfil acceptance criteria. Evidence of interchangeability of patient results was obtained for all parameters except magnesium, NT-proBNP, cTroponin I and C-reactive protein.
Conclusions:
A laboratory having a well structured and documented validation procedure can opt to get a flexible scope of accreditation. In addition, performing these activities prior to use on patient samples may evidence technical issues which must be corrected to minimize their impact on patient results. 相似文献
Purpose: This study uses data from a sample of 150 oilseed farming households from Arsi Robe, Ethiopia, to assess the impact of different knowledge bases (education, training and experience) and their interactions on linseed productivity.
Methodology: A multiple regression analysis was employed to assess the combined effect of the knowledge bases, factors such as age of the household head, land size, marketing channels and geophysical factors (such as land slope) on linseed productivity.
Findings: The findings reveal no differences in productivity between trained and untrained farmers. They further show that training and the interaction between training and experience positively influence productivity. Our findings, however, reveal farmer education to have an inverse yet insignificant effect on productivity. Furthermore, we found that factors such as the slope of the land and the choice of marketing channel also play an important role in influencing productivity.
Practical implications: Moving away from the traditional top-down approach could be the answer to avoid a mismatch between the information given by trainers and what the farmers actually need.
Theoretical implications: The study used interaction variables of knowledge bases, and attempted to demonstrate the importance of a tacit knowledge base, which is often not well documented and therefore neglected in research.
Originality/value: The research demonstrates the combined effects that interactions between several knowledge bases have on the productivity of linseed farmers. 相似文献
This study reports on the development of a self-reported measurement instrument – The Teacher Educators’ Researcherly Disposition Scale (TERDS) – to improve understanding of teacher educators’ researcherly disposition. Teacher educators’ researcherly disposition refers to the habit of mind to engage with research – both as consumers and producers – to improve their practice and contribute to the knowledge base on teacher education. Taking into account the shortcomings of the emerging field of teacher educator professional development research (which is largely confined to small-scale, qualitative studies), a large-scale quantitative survey study (n?=?944) was conducted. The first part of the article reports the results of factor analysis (EFA and CFA), which suggest a four-factor structure of teacher educators’ researcherly disposition: (1) ‘valuing research’ (α?=?.86), (2) ‘being a smart consumer of research’ (α?=?.89), (3) ‘being able to conduct research’ (α?=?.82), and (4) ‘conducting research’ (α?=?.87). Goodness of fit estimates were calculated, indicating good fit. The second part of the article explores differences in teacher educators’ researcherly disposition across several subgroups of teacher educators using the developed instrument. Results indicate that having research experience leads to significantly higher scores on each of the subscales. Furthermore, significantly higher scores were found for those with more than 3 years’ experience as a teacher educator, as well as for those without (prior) teaching experience in compulsory education. To conclude, the implications for further research and practices related to teacher educators’ professional development are discussed. 相似文献
Even though teachers are key figures of a program's effectiveness, most intervention studies have not focused explicitly on the effects of antibullying programs at teacher level. We conducted a meta‐analysis into the effects of school‐based antibullying programs on determinants of teacher intervention, including teachers’ attitudes towards bullying, their self‐efficacy and knowledge regarding intervention strategies, and the effects on teachers’ bullying intervention itself. Following the PRISMA guidelines, 13 peer‐reviewed papers were retrieved that reported outcomes on teachers, staff, and students (N = 948, 2,471, and 138,311, respectively). Antibullying programs had a significant moderate effect on determinants of teacher intervention (g = 0.531) and a significant small to moderate effect on teacher intervention in bullying situations (g = 0.390). Results of the meta‐analysis indicate that the effectiveness of antibullying programs may increase when components are included to reinforce teachers’ attitudes, subjective norms, self‐efficacy, knowledge, and skills towards reducing bullying in the school. 相似文献
AbstractThis study reports on the design of a video-based instrument to assess student teachers’ parent–teacher communication competences (PTCC) in a reliable and valid way. PTCC refer to the competences needed to communicate successfully with parents during conversations such as parent–teacher conferences. Taking into account both conceptual and methodological challenges regarding the measurement of competences, several methodological steps were followed to design a video-based instrument focusing on the assessment of student teachers’ perception, interpretation and decision-making skills (PID skills) regarding parent–teacher communication: designing video vignettes presenting realistic job situations regarding parent–teacher communication; developing instructions to elicit student teachers’ PID skills; designing a coding scheme to analyse student teachers’ responses; and implementing the instrument (n = 269) to test and refine it. This ultimately resulted in an instrument consisting of (1) three video vignettes, (2) a series of open-ended questions eliciting student teachers’ PID skills, and (3) three coding schemes to develop a perception score, an interpretation score and a decision-making score for PTCC. The (4) implementation of the instrument confirmed that this innovative video-based tool might be a promising approach to assess student teachers’ PTCC. To conclude, the quality and contribution of the measurement instrument and the implications for further research are discussed. 相似文献
This article reports on the effects of individual background characteristics, classes, and schools on 4 noncognitive outcomes at the end of the 1st cycle secondary education in Flanders. The outcomes are: the degree to which the student feels at home in the school environment, the extent to which the student does his/her best for the school work, the academic self-concept, and the social integration in the class. Firstly, the raw class and school effects are estimated. Secondly, a broad set of background variables is introduced to isolate the net class and school effects. Thirdly, class and school composition variables are introduced. Finally, the additional predictive power of a number of other student, class, and school characteristics is documented. 相似文献
