The mediating roles of internal context variables in the relationship between distributed leadership perceptions and continuous change behaviours of public school teachers

This study aims at building a theoretical base for continuous change in education and using this base to test the mediating roles of two key contextual variables, knowledge sharing and trust, in the relationship between the distributed leadership perceptions and continuous change behaviours of teachers. Data were collected from 687 public school teachers. The results showed that the combined effect of knowledge sharing and faculty trust in principal mediated the relationship between teachers’ distributed leadership perceptions and continuous change behaviours. The directions of the coefficients of the relationships between the independent variable and the dependent variable suggested that higher distributed leadership perception leads to increased knowledge sharing and trust in principal, which in turn was associated with greater continuous change behaviours. The study showed that school systems have an extensive capacity for self-improvement, even in the absence of a pre-developed change plan.     

Diffusion of distance education in Turkish higher education

Conclusion In this paper, Rogers's diffusion theory was used to analyze the acceptance and implementation of the innovation of distance education in higher education in Turkey. Distance education was not successfully adopted between 1970 and 1980 in Turkey because of organizational problems. Distance education was effectively and efficiently diffused in Turkey after 1982. Thousands of students today earn university diplomas studying at a distance. On the other hand, problems of organization, technology, and perceptions remain to be addressed. It is to be hoped that in the future the OEF will be independent or have more autonomy. This will help it deliver instruction to its students.the evaluator of the Learning Community Link Project at the University.     

Pre-service teachers’ cultural and teaching experiences abroad

This study investigates Turkish pre-service teachers’ experiences related to a two-month international teaching and cultural experience in the United States of America. In total, 289 graduate students from Turkey participated in a collaborative project from 2001 to 2010. The experience included an orientation week, six weeks of student teaching in a high school, seminars and projects at Iowa State University and cultural visits. The data were collected through a pre-service teacher questionnaire and their reflective journals. The results showed that pre-service teachers perceived the international teaching experience helped them develop professionally and personally. Through cross-cultural exchanges with their mentors along with other students and their community, the pre-service teachers expanded their knowledge of a new culture and adapted to a new working environment.     

Professional competences to teach English at primary schools in Turkey: a Delphi study

This research aimed to uncover the teacher competences that are necessary to provide age-appropriate English language teaching to primary school students in Turkey. The Delphi technique was implemented to propose a list of competences created through consensus among a panel of experts that consisted of 15 teachers and 16 teacher educators. The data were collected by administering three questionnaires in three rounds. Central tendency and consensus were measured through median and inter-quartile range, respectively. The findings led to a list of 29 teacher competences which were categorised into five groups: ‘theoretical and practical knowledge’, ‘knowing the young learner’, ‘planning and organising teaching’, ‘managing teaching’, and ‘competence in English’. Implications were made for improving the effectiveness of English language teaching to young learners: these included the design of pre-service and in-service teacher education programmes to equip teachers with the necessary skills and knowledge to teach English to young learners.     

Interaction between seed size and NaCl on germination and early seedling growth of some Turkish cultivars of chickpea （Cicer arietinum L.）

Chickpea is an important food legume crop of Turkey and is largely grown for human consumption on low moisture or salt-affected soils.The objective of the study was to find the effects of NaCl stress at electrical conductivities of 4.5,8.6,12.7 and 16.3 dS/m and seed sizes (7,8 and 9 mm) on germination and early seedling growth of three popular chickpea cultivars (AKN-97,Gokce and Uzunlu-99).Mean frequency of germination,germination time,germination index,root length,shoot length and seedling fresh weight showed seed size-dependent responses of cultivars to salt stress.In general,small seeds germinated and grew more rapidly compared to medium and large seeds of the same cultivars against all levels of salt stress,with the best results in cultivar Uzunlu-99.No effect of NaCl treatments was observed on frequency of germination; however,a drastic decrease in early seedling growth was recorded at increased NaCl concentrations.Regression analysis results showed a significantly positive rela-tionship (P<0.01) between seed size and mean germination time,whereas a significantly negative relationship was recorded between seed size and germination index,root length,shoot length.Moreover,linear regression values apparently confirmed that increased seed size in each cultivar affected decreased germination index,root and shoot lengths with enhanced mean germination time.Thus,it was concluded that the use of small seeds could considerably reduce the production costs of chickpea in salt-affected soils.     

Measuring the perceived quality of an AR-based learning application: a multidimensional model

Augmented reality (AR) technologies could enhance learning in several ways. The quality of an AR-based educational platform is a combination of key features that manifests in usability, usefulness, and enjoyment for the learner. In this paper, we present a multidimensional model to measure the quality of an AR-based application as perceived by students. The model is specified by a second-order factor (perceived quality) and three dimensions: ergonomic quality, learning quality, and hedonic quality. The purpose of this model is to embody previous research into a coherent framework for the evaluation of AR-based educational platforms and to provide guidance for researchers and practitioners. The model was empirically validated on a Chemistry learning scenario and the results confirm the importance of both the learning and hedonic quality.     

Polynomial solution of high-order linear Fredholm integro-differential equations with constant coefficients

In this study, a practical matrix method is presented to find an approximate solution of high-order linear Fredholm integro-differential equations with constant coefficients under the initial-boundary conditions in terms of Taylor polynomials. The method converts the integro-differential equation to a matrix equation, which corresponds to a system of linear algebraic equations. Error analysis and illustrative examples are included to demonstrate the validity and applicability of the technique.     

Evaluation of a mobile information system in context

The motivation for this work has been to provide relevant information to the right situation for mobile phone users. We have iteratively developed applications for travellers and tourists to provide a general travel guide with local tourist information. This used a combination of wireless tag technology and information from content service providers. The paper presents our evaluation methodology and how we used it to develop the applications.
