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. 相似文献

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. 相似文献

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. 相似文献

Though environmentally responsible behavior (ERB) has been a focus of many studies in the field of environmental education, very few scales have been developed to assess children’s ERB. In this regard, this article focuses on the development and validation of Children’s Responsible Environmental Behavior Scale (CREBS) and also reports the psychometric properties of this scale. The items in the CREBS were developed initially from the responses to four open-ended items by 229 fourth and fifth grade students. This initial form was pilot tested with 673 fourth and fifth graders and then subjected to exploratory factor analysis. Later, the revised version of the scale was administrated to 2412 fifth graders, and those results were subjected to confirmatory factor analysis and reliability analysis. CREBS consists of 23 items measured using a seven-point Likert-type scale, which have been organized into four sub-scales: political action (six items, α?=?.92); eco-management (six items, α?=?.70); consumer and economic action (five items, α?=?.70); and Individual and Public Persuasion (six items, α?=?.80). Study results indicate that CREBS can be used for exploring the extent to which elementary school students in Turkey demonstrate four types of behavior to help prevent and resolve environmental problems and issues. 相似文献

This paper describes beliefs held about teaching and learning chemistry by Turkish teachers and student-teachers. The study investigated different aspects of pre-service and in-service teachers’ belief structures. Part of the study examined teachers’ overall beliefs, based on participants’ drawings of classroom situations. A qualitative evaluation was employed to offer information on (student-)teachers’ beliefs about classroom organisation, their beliefs about teaching objectives, and their stance on epistemological beliefs. Beliefs ranged from very traditional, teacher-centred ideas to modern, student-centred ones. Data evaluation was triangulated using a quantitative approach, which focused on whether beliefs were characterised by either teacher-centredness or learner-centredness. Additionally, a Likert questionnaire was used to evaluate the educators` beliefs about the nature of good education. The results for the group of participants are presented and compared. Implications for chemistry teacher education in Turkey will also be addressed. 相似文献

Technology has already become an indispensable part of our lives, and nations around the world see schools as the main agents to prepare their youth for a technology-filled future, and invest important amounts of funding to provide hardware to schools, students and teachers. The Turkish Ministry of National Education is in the midst of the FAT?H project, a nation-wide attempt to provide each classroom with an interactive whiteboard and each student with a tablet computer. In this paper, the authors present interview data from teachers at first-year FAT?H pilot schools who are using these technologies to understand how this national attempt is being translated into practice, and identify what is working and what areas need further attunement. Results show that teachers were especially content with being able to make their lessons visually more appealing for their students. They were, however, not satisfied with the in-service training provided, especially in understanding ways to effectively integrate the technologies into their teaching, and the limitations put upon Internet access from the tablets. The impacts of these tools on their teaching practices were very minimal. 相似文献

This article introduces an exercise that simulates the negotiation process in a dynamic supply chain. The retailer and wholesaler roles are assigned to student groups who negotiate supply contracts in a number of rounds during a class period. Each group makes pricing, inventory, and ordering decision concurrently, and competes with others to achieve the highest profit. The exercise is easy to implement using pen and paper, and lends itself to a wide variety of negotiation environments. 相似文献

This study investigated the effects of problem-based learning on students’ beliefs about physics and physics learning and
conceptual understanding of Newtonian mechanics. The study further examines the relationship between students’ beliefs about
physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish university students (PBL = 55,
traditional = 69) enrolled in a calculus-based introductory physics class. Students’ beliefs about physics and physics learning
and their physics conceptual understanding were measured with the Colorado Learning Attitudes about Science Survey (CLASS)
and the Force Concept Inventory (FCI), respectively. Repeated measures analysis of variance of how PBL influence beliefs and
conceptual understanding were performed. The PBL group showed significantly higher conceptual learning gains in FCI than the
traditional group. PBL approach showed no influence on students’ beliefs about physics; both groups displayed similar beliefs.
A significant positive correlation was found between beliefs and conceptual understanding. Students with more expert-like
beliefs at the beginning of the semester were more likely to obtain higher conceptual understanding scores at the end of the
semester. Suggestions are presented regarding the implementation of the PBL approach. 相似文献

This qualitative–case study examined how portfolio and portfolio assessment were perceived by prospective teachers. The participants
were 23 prospective teachers from seven different teaching areas from a Turkish university. A semi-structured individual interview
was conducted. The interview schedule included 15 open-ended questions. The main results emerged from content analysis were
that prospective teachers perceived portfolio as a learning and an assessment tool. Further, they believed that portfolio
was complementary rather than an alternative assessment method to traditional assessment procedures. 相似文献
