This research aims to unearth the educational challenges experienced by teachers and communities in rural Turkey. The research employs Nancy Fraser’s three dimensional justice approach – distribution, recognition and participation – to frame these challenges and to argue that rural challenges go beyond economic rationalities and concerns of infrastructure and resources. The study draws its data from 29 in-depth interviews with 20 teachers working in 16 different villages; 9 interviews with community members; and 2 focus group interviews, 1 with rural dwelling women and the other with rural dwelling men. The findings point out four significant difficulties that impede community and educational development: scarcity of resources; insufficient understanding of social, cultural and economic contexts that constrain educational attempts; lack of collaboration between teacher and communities; and irrelevant education. The study concludes by scrutinising how these difficulties interact with one another and result in marginalisation or casting out of rural lives. 相似文献

The study aimed to test the validity and reliability of the Very Short form of the Physical Self-Inventory (PSI-VS) among a sample of 635 Turkish adolescents. These adolescents have completed the 12 original items of the PSI-VS, plus a positively worded reformulation of the single reverse-keyed item of the physical attractiveness subscale. A series of confirmatory factor analyses was used to examine the psychometric properties of the original and modified versions of the PSI-VS. Findings revealed superior psychometric properties with the modified version than with the original set of items. The modified version was thus subsequently used to examine its factor structure invariance across sexes, age groups and sport practice involvement. Results not only report that this version was fully invariant across, but also that latent means were significantly different across sexes and sport practice involvement. In sum, the Turkish modified version of the PSI-VS presents acceptable psychometric properties and may be used to repeatedly and/or intensively assess participants’ physical self-perceptions in the context of sport and exercise interventions. 相似文献

Teachers’ views on the effectiveness of in‐service courses on the new curriculum in Turkey 总被引:1,自引:1,他引:0
This study aims to evaluate the effectiveness of in‐service courses conducted by the Ministry of National Education in order to inform teachers about the changes introduced by the new primary and secondary school curricula. The study also aims to reveal whether these changes have entered the classrooms based on the teachers’ views of the INSET courses they attended. For this purpose, semi‐structured interviews were conducted with both primary and secondary school teachers during the 2007–2008 academic year. Data were analysed based on the effective INSET criteria identified from the literature. According to the findings, the INSET courses were found to be ineffective, mainly in terms of the quality of the instructors, teaching methods employed, duration of the courses and support after training. Suggestions to conduct effective INSET courses, especially when change is afoot, are included at the end of this paper. 相似文献

The purpose of this study was to model the relationship between pre-service chemistry teachers’ epistemological beliefs and their preference to use constructivist-learning environment in their future class. The sample was 125 pre-service chemistry teachers from five universities in Turkey. Two instruments were used in this study. One of the instruments was constructivist-learning environment scale developed by Taylor, Fraser and Fisher. The other instrument was Epistemological Questionnaire (EQ) developed by Schommer. In order to analyse data, Structural Equation Modelling was conducted by using LISREL 8.7. The results provided evidence for the good fit of the hypothesised model. Pre-service chemistry teachers’ epistemological belief scores were found to be correlated to their constructivist-learning environment scale scores with the value of .35. This study revealed that pre-service chemistry teachers with sophisticated epistemological beliefs favoured constructivist-learning environment in their future class. 相似文献

The aim of this study is to investigate the effectiveness of conceptual change oriented instruction (CCOI) over traditionally
designed chemistry instruction (TDCI) on overcoming 10th grade students’ misconceptions on gases concepts. In addition, the
effect of gender difference on students’ understanding of gases concepts was investigated. The subjects of this study consisted
of 74 10th grade students from two chemistry classes. One of the classes was assigned as experimental group and the other
group was assigned as control group. The experimental group was instructed with CCOI and the control group was instructed
by TDCI. Gases Concept Test (GCT) was administered to both groups as pre- and post-tests to measure the students’ conceptual
understanding. The results showed that students in the experimental group got higher average scores from Gases Concept Test.
Also, a significant difference was found between the performance of females and that of males in terms of understanding gases
concepts in favor of males. 相似文献

Since Proportional?+?Integral?+?Derivative (PID) controller is still the workhorse in taking over the workload of process control systems, this article introduces a new design methodology toward improving the performance of such controller. After a PI control law with windup protection is given, it is combined with a derivative path employing a first-order low pass filter in an innovative way to develop a performant controller called PI?+?DF controller. In attempting to attain a high level of control performance, gains of this controller including proportional, integral, derivative and filter gains are tuned choosing the recently introduced Stochastic Fractal Search (SFS) algorithm owing to its superiority to many state-of-the-art algorithms considering convergence, accuracy and robustness. To evaluate the efficacy of SFS, Particle Swarm Optimization (PSO) is also applied to the case study. Furthermore, the presented SFS optimized PI?+?DF controller is compared to a recently reported control scheme through simulation and experimental tests on an identical DC servo system. After providing the stability proof, SFS tuned PI?+?DF controller is found to be the pioneer in exhibiting the most accurate speed response profile under complicated scenarios, which is followed by PSO tuned PI?+?DF controller and the existing control approach, respectively. 相似文献

We describe how 1 Algebra I teacher and her 8th-grade students used meta-representational knowledge when generating and evaluating equations to solve word problems. Analyzing data from a sequence of 4 lessons, we found that the teacher and her students used criteria for evaluating equations, in addition to other types of knowledge (e.g., different interpretations of the equal sign) previously reported in the literature. Moreover, the teacher and her students had trouble understanding one another's proposed algebraic models of problem situations due to differences in the criteria that each applied, and this impeded learning. These findings (a) extend an accumulating body of evidence for the role meta-representation plays in mathematics and science learning and (b) add a new dimension to researchers' growing understanding of what teachers must know in order to teach algebra and other complex mathematics and science topics effectively. 相似文献
