This study sought to explore the relationship between mindfulness, coping self-efficacy (CSE) and foreign language anxiety (FLA) among a sample of 295 Iranian English as a foreign language (EFL) learners. Further, the capacity of CSE in mediating the relationship between mindfulness and FLA was tested. The participants were administered self-reported questionnaires. Structural equation modelling (SEM) was utilised. The results of SEM analysis showed that higher levels of mindfulness were associated with lower levels of FLA and greater CSE. In addition, it was found that CSE could partially mediate the relationship between mindfulness and FLA. Implications are discussed. 相似文献

This study examined the relationship between student ratings and instructors’ predictions of these ratings, taking into account other instructor, student, and course characteristics. Participants in the study were 198 instructors in the School of Education at a major teacher training college in Israel. Data corresponding to one randomly selected course per instructor were collected using student and instructor questionnaires and college records. Results indicate a systematic positive relationship between instructors’ predictions and actual student ratings with respect to overall ratings and the ratings of three dimensions of teaching. Results also demonstrate a systematic trend whereby low‐rated instructors tend to overestimate their student ratings, high‐rated instructors underestimated ratings, and moderately rated instructors gave accurate predictions. Results have implications for using predictions to motivate teaching improvement. 相似文献

Massive oil revenues are currently fueling a surge in the number of educational institutions in the Gulf Cooperation Council (GCC) countries, presenting leadership at all levels with many unprecedented questions. In particular, the growth and reform of higher education challenges the delicate balance between academic freedom and Arab cultural values. This paper describes faculty perceptions of academic freedom at a major GCC national university. Faculty members’ views and perceptions regarding academic freedom are presented based on interviews, questionnaire responses, and the authors’ own thoughts. Findings indicate that faculty members have complex and often contradictory understandings of academic freedom and related responsibilities and often engage in self-censorship. The authors discuss these findings by engaging in self-reflection regarding their own perspectives and personal experiences. 相似文献

A fast and efficient page ranking mechanism for web crawling and retrieval remains as a challenging issue. Recently, several link based ranking algorithms like PageRank, HITS and OPIC have been proposed. In this paper, we propose a novel recursive method based on reinforcement learning which considers distance between pages as punishment, called “DistanceRank” to compute ranks of web pages. The distance is defined as the number of “average clicks” between two pages. The objective is to minimize punishment or distance so that a page with less distance to have a higher rank. Experimental results indicate that DistanceRank outperforms other ranking algorithms in page ranking and crawling scheduling. Furthermore, the complexity of DistanceRank is low. We have used University of California at Berkeley’s web for our experiments. 相似文献

The purpose of the current study was to define the impact of regular practice of Nordic walking on the gait of the elderly. Thereby, we aimed to determine whether the gait characteristics of active elderly persons practicing Nordic walking are more similar to healthy adults than that of the sedentary elderly. Comparison was made based on parameters computed from three inertial sensors during walking at a freely chosen velocity. Results showed differences in gait pattern in terms of the amplitude computed from acceleration and angular velocity at the lumbar region (root mean square), the distribution (Skewness) quantified from the vertical and Euclidean norm of the lumbar acceleration, the complexity (Sample Entropy) of the mediolateral component of lumbar angular velocity and the Euclidean norm of the shank acceleration and angular velocity, the regularity of the lower limbs, the spatiotemporal parameters and the variability (standard deviation) of stance and stride durations. These findings reveal that the pattern of active elderly differs significantly from sedentary elderly of the same age while similarity was observed between the active elderly and healthy adults. These results advance that regular physical activity such as Nordic walking may counteract the deterioration of gait quality that occurs with aging. 相似文献

This study was conducted among Arab teachers in four countries in the Middle East (Jordan, Lebanon, Egypt and Palestine) to examine their views and methods on teaching for forgiveness in their classrooms. A total of 87 teachers in K-12 classrooms participated in semi-structured interviews as part of a larger study on teaching for forgiveness in the region. Thematic analyses of interviews suggested that teachers created opportunities to model and teach forgiveness as part of their civics education curriculum. They also expressed eagerness for instructional guidance and curriculum materials to systematically teach forgiveness in schools. The strength of religion and historical religious figures as positive sources for teaching forgiveness was also evident. Findings highlight the need to integrate education for peace and forgiveness in the education system, especially as a result of recent political developments in the Middle East, and to provide methods to assist teachers to do so in their classrooms. 相似文献

This classroom observation study explored how science teachers (N = 22) teach for creativity in grades 5–10 in Oman. We designed an observation form with 4 main categories that targeted the instructional practices related to teaching for creativity: questioning strategy, teacher’s responses to students’ ideas, classroom activities to support creativity, and whole-lesson methods that foster creativity. An open-ended survey was also designed to explore participants’ justifications for their instructional decisions and practices. The findings indicate that the overall level of teaching for creativity was low and that participants’ performance was the highest for teacher’s responses to students’ ideas category and the lowest for classroom activities to support creativity category. We observed that a teacher-centered approach with instructional practices geared toward preparing students for examinations was dominant and that these science teachers were bound to the textbook, following cookbook-style activities. Participants believed that they did not have enough time to cover the content and teach for creativity and that they were not prepared to teach for creativity. Based on these findings, we recommend that programs be developed to prepare science teachers to teach for creativity. 相似文献

Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students’ learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students’ inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists’ practices is very much needed. Within this context there is a need to re-examine the science teachers’ views of scientists and the cultural factors that might have an impact on teachers’ views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative–qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers’ cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists. 相似文献
