The current study aimed to investigate the role of teaching experience in language teachers’ perceptions of a top-down curriculum change. One hundred twenty-seven language teachers who have been experiencing the change for three years participated in the study. Their perceptions of change were quantitatively assessed by perceptions of change survey with three main components: new curriculum, teacher practices, and administrative support of change. Analysis of the quantitative data analysis indicates that experience is associated with more cautious perceptions of change and explains 9% of the variance in the results. To triangulate the findings of the quantitative data analysis, 10 experienced and 8 novice teachers took part in a structured interview and answered 10 questions regarding the old curriculum and the change, their role in the reform, and the administrator's support of the change. The result showed that both experienced and novice teachers are optimistic about the new syllabus. However, experienced teachers are more concerned about the practical issues of change such as time and lack of audiovisual aids. Further, they think that their agency and experiential professionalism are neglected in this change and the problems of implementing change have not been appropriately addressed by the administrators during the last three years. 相似文献

A credible scale based on the opinions of system users was developed to evaluate and assess data quality in automated library systems (ALS). Development and testing were carried out in two stages. In the first stage, 77 dimensions for data quality which had been previously identified through a systematic literature review were used to develop scale items. The first draft of the scale was then distributed among a target population of ALS experts to solicit their opinions on the scale and the items. In the second stage, a revised version of the scale was distributed among the main study population, which included end users of the target systems. This stage used factor analysis to determine the final draft of the scale, which consists of 4 factors and 62 items. The 4 factors were named after the qualities of their associated items: Data Content Quality, Data Organizational Quality, Data Presentation Quality, and Data Usage Quality. This scale can help system managers identify and resolve potential problems in the systems they manage and can also aid in evaluating the quality of data sources based on the opinions of end users. 相似文献

In this paper,a geometric approach to fault detection and isolation (FDI) is applied to a Multiple-Input Multi-ple-Output (MIMO) model of a frame and the FDI results are compared to the ones obtained in the Single-Input Single-Output (SISO),Multiple-Input Single-Output (MISO),and Single-Input Multiple-Output (SIMO) cases. A proper distance function based on parameters obtained from parametric system identification method is used in the geometric approach. ARX (Auto Regressive with eXogenous input) and VARX (Vector ARX) models with 12 parameters are used in all of the above-mentioned models. The obtained results reveal that by increasing the number of inputs,the classification errors reduce,even in the case of applying only one of the inputs in the computations. Furthermore,increasing the number of measured outputs in the FDI scheme results in decreasing classification errors. Also,it is shown that by using probabilistic space in the distance function,fault diagnosis scheme has better performance in comparison with the deterministic one. 相似文献

The h-index of Scopus is used as an important and practical instrument in analyzing the scientific level of researchers. In this research, 6 effective items (including author’s order, quality of publication source, quality of citation source, type of citation, research scopes of the authors and the regular scope of citation source) were considered in order to increase the accuracy and equity of research and also the optimization of scientometrics. In order to find the actual impact of each item, a relation with a default coefficient was considered, and all effective items were presented after evaluating the influence of them on the desired coefficients. Here, the introduced effective factors were separately investigated for 20 Iranian authors who are randomly selected. The analysis of the results showed that by applying the effective factors, the h-index of authors was obtained on the basis of real and scientific criteria; thus, the mean of all effective factors is introduced as modified h-index. Among considered authors, the lowest reduction in h-index was 10.67% and the highest reduction was 37.25% (SD was 6.5). This reduction was obtained in comparison with their h-index of Scopus, and it demonstrates that the authors, who have less reduction in their h-index value, have more scientific and honest approach to research. 相似文献
