Reforms in education often fail due to insufficient time to implement them, too few charismatic leaders, the influence of the preceding culture, scarce resources or an incapacity to comprehend the complexity of the education system. Most studies dealing with the cognitive aspects of educational change investigate the meaning of change through the lens of the educators and principals and there is not as much research available on the perception and interpretation of change by policy makers and the language they use to communicate messages about policy that affect sensemaking–sensegiving during the process of learning about the changes. Guided by the premise that the language of a reform movement is shaped by its ideology, this article illustrates how press releases of the Ministry of Education in Canton Sarajevo in Bosnia–Herzegovina reflect an exploitation-oriented dominant reform logic. The results of frequency analysis, hierarchical clustering and multidimensional scaling imply that MoE is driven by a top-down perspective to educational change, with a focus on the procedural, organizational and collaborational aspects of reforms that primarily alter the structure of the education system but not its internal substance. We end this paper by suggesting that educational system as complex adaptive system cannot be controlled, but effectively managed through distribution of control and creation of few attractors, benefiting from self-organization in the technical core and making change in the official top-down rhetoric. 相似文献

This paper studies the neural adaptive control design for robotic systems with uncertain dynamics under the existence of velocity constraints and input saturation. The control objective is achieved by choosing a control Lyapunov function using joint error variables that are restricted to linear growth and furthermore by introducing a secant type barrier Lyapunov function for constraining the joint rate variables. The former is exploited to bind the forward propagation of the position errors, and the latter is utilized to impose hard bounds on the velocity. Effective input saturation is expressed, and neural networks are employed to tackle the uncertainty problem in the system dynamics. Feasibility conditions are formulated, and the optimal design parameters are obtained by solving the constrained optimization problem. We prove that under the proposed method, semi-global uniform ultimate boundedness of the closed-loop system can be guaranteed. Tracking errors meanwhile converge to small neighborhoods of the origin, and violations of predefined velocity constraints are avoided. Finally, numerical simulations are performed to verify the effectiveness of the theoretical developments. 相似文献

Over recent decades, educators have recognized the crucial importance of teaching environment and contextual factors in teaching
and learning outcomes. Public and private schools are among those teaching contexts that have been in competition for teaching
quality and effectiveness for many years. This study investigated the effectiveness of some English teachers in these two
school contexts in a foreign language setting, Iran. Seventy-six public and private high schools in a small city in Iran were
selected, and their English teachers’ performance was evaluated by an external observer and self-evaluation using a high-inference
observation instrument and a questionnaire. The result of the data analysis showed that English teachers who worked in private
schools were more effective teachers than their colleagues in public schools. The results also revealed that teacher effectiveness
and their years of teaching experience and age were weakly but significantly related. Furthermore, it was found that teachers’
type of university degree and the location of schools (disadvantaged vs. privileged areas of the city) were not related to
teachers’ effectiveness. 相似文献

Sexual harassment is a highly troubling gendered phenomenon that plagues young women on a daily basis. The way in which sexual harassment is perceived and treated is varied and is largely based on racial and class stereotypes. This paper highlights the findings from a study in which a group of middle and high school teachers were interviewed and their perceptions of sexual harassment on their campuses were discussed. What was revealed throughout this study was the way in which many teachers’ notions of sexuality are conceptualised through their notions of class and race. This paper addresses how such racial and class stereotypes veil the sexual victimisation of many young women. 相似文献

In recent educational literature, it has been observed that improving student's control has the potential of increasing his or her feeling of ownership, personal agency and activeness as means to maximize his or her educational achievement. While the main conceived goal for personal learning environments (PLEs) is to increase student's control by taking advantage of Web 2.0 tools and technologies, there is not a robust learning model available to achieve it. This contribution focuses on proposing a learning model built upon self‐regulated learning and student's control theories and concepts, and supported by the learning affordances of Web 2.0 tools and technologies for enhancing student's control by developing and applying Web 2.0 PLEs. 相似文献

Over the years, the multiple intelligences theory (MIT) proposed by Howard Gardner has renewed interest in learners’ use of effective learning strategies and produced interesting results. This MIT-oriented study investigated the role of successful L2 readers’ multiple intelligences in their effective use of reading strategies. To this end, a TOEFL reading comprehension test was administered to a cohort of 135 English as a foreign language students at several universities in the southwest and centre of Iran, and 80 students were identified as successful L2 readers based on the ETS rating scale and their TOEFL scores. Then, they answered an MI questionnaire originally developed by Armstrong and a reading strategies inventory adapted by Singhal. The data were quantitatively analysed using correlations and multiple regressions. The results revealed that linguistic, logical–mathematical and intrapersonal intelligences were the good L2 readers’ most dominant intelligences, while bodily intelligence was the least common type. In addition, they mostly employed metacognitive and cognitive strategies but rarely drew upon affective and compensation strategies while reading. Further, there was a significant positive relationship between linguistic, logical–mathematical, spatial, interpersonal, and intrapersonal intelligences and the use of metacognitive and cognitive reading strategies. Similar relationships were also found between linguistic intelligence and the participants’ use of memory strategy, on one hand, and between interpersonal intelligence and compensation and social strategy use, on the other. Importantly, linguistic and intrapersonal intelligences as well as metacognitive and cognitive strategy use were shown to be the best predictors of reading comprehension. Finally, the theoretical or pedagogical implications of the findings are discussed. 相似文献

Feelings of threat, challenge, motivation, self-efficacy, and transactional distance reflect students’ struggles with the learning process. This study examined the relationship between students’ subjective feelings about the learning process in virtual and blended courses (VC and BC). This is a mixed-method study. The sample included 484 students from two academic institutions in Israel. The study found a connection between students’ subjective feelings about the learning process in VC and BC and feelings of threat/challenge, motivation, and self-efficacy. We found differences between students in different years of study and between those studying in various fields of study. 相似文献

This study investigates cognitive and metacognitive strategies in learning oral Arabic among students at Universiti Teknologi MARA (UiTM), Malaysia. The concept of these strategies was derived from the self-regulated learning framework, which consists of five components, namely rehearsal, elaboration, organization, critical thinking, and metacognitive strategies. The purposes of this study are to investigate the level of cognitive and metacognitive strategies used (1) among UiTM students; (2) between students with different prior experiences, namely, some of them had an experience of 5 years in learning Arabic in secondary school (abbreviated by SWE) and some of them did not have any experience at all (abbreviated by SNE); (3) between students of different gender; and (4) between students with the interaction of different gender and prior experience. The sample of this study consists of 183 students and employs a questionnaire adapted from the Motivated Strategies for Learning Questionnaire (MSLQ). The study revealed that (1) all UiTM students used cognitive and metacognitive strategies at a moderate level; (2) SWE scored significantly higher than SNE in all five components of cognitive and metacognitive strategies; (3) females scored significantly higher than males in rehearsal, organization, and metacognitive strategies; and (4) there were no statistically significant differences noted in all components between students with the interaction of prior experience and gender. This study had some classroom implications. It suggested that some improvement and changes in learning oral Arabic should be made in terms of selecting learning materials, implementing oral Arabic activities, and learning tasks, which will stimulate the use of all strategies, as well as conducting proficiency tests instead of achievement tests. Students should also be exposed to the learning techniques which used all these strategies extensively and collaborative activities may be carried out among students with mixed prior experience and gender. 相似文献
