Students have long regarded science as a difficult subject because of hard and abstract concepts. Traditional science teaching has been depended mostly on visual instruction. This makes it difficult for visually impaired （VI） or partially sighted students included in regular classrooms to learn the concepts. Blind students on the other hand, have no visual input at all. They need to learn using other senses such as touching and hearing. Classrooms should be adapted and instruction should be adjusted for better science teaching to VI students. The purpose of this study was to investigate how VI students learn science. The results of the data obtained via interviews and observations revealed that VI students need instructional and environmental accommodations to learn science. They need more tactual and audio experiences than visual instruction. Suggestions and implications about teaching science to students with visual impairments are discussed. 相似文献

The present study aims to identify first year Turkish Science undergraduates’ understandings and misconceptions of the concept
of light and its propagation. For this purpose, an instrument composed of four open-ended questions was developed by the researchers.
The diagnostic test was piloted with twenty students and modifications were made prior to the final administration of the
test. The content validity of the test questions was assessed by two physics researchers and one lecturer. These questions
were administered to a hundred first year undergraduates (aged 16–18) enrolled in the Science Teacher Training Department
in Ataturk University in Turkey. In addition, the semi-structured interviews of 30–40 min were conducted with the four students
whose responses involved common misunderstanding. All interview records were transcribed and analysed. The findings showed
that undergraduates’ understanding of light is poor and also they have important and prevalent misconceptions. Identified
misconceptions, some of which have been reported in the literature, are discussed qualitatively. The misunderstandings identified
were compared with those in the literature. The results have some implications for teaching light, suggesting that a substantial
revision of teaching strategies is needed.

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. 相似文献

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

Study provides qualitative analysis of data that answers the following research question: how college science faculty teach science and NOS and incorporate aspects of NOS and the history of science into their undergraduate courses? Study concentrates on four cases and more specifically on three introductory science classes and on four instructors who taught those courses. These instructors were chosen as case studies to explore in greater detail what occurs inside introductory science courses in one particular higher institution in the Northeastern United States. Participants’ teaching styles are presented through a combined and detailed presentation of interview data and classroom observations supported with examples from their classroom activities. Constant comparative approach was used in the process of organizing and analyzing data. Findings revealed that participants preferred to use the traditional teacher-centered lecturing as their teaching style and whose main concern was to cover more content, develop the problem solving skills of their students, and who wanted to teach the fundamental principles of their subjects without paying special importance to the NOS aspects. The study also revealed that other variables of teaching science, such as large class size, lack of management and organizational skills, teaching experience, and instructors’ concerns for students’ abilities and motivation are more important for these scientists then teaching for understanding of NOS. 相似文献

This study aimed to analyze environmental education research (EER) in Turkey conducted in Grades K‐8 and published over the years 1997–2007. Due to the fact that there had been no systematic reviews of EER in Turkey prior to this time period, it was more appropriate to explore the implications of the results of this review for research policies and practices than for educational policies and practices in Grades K‐8. A substantial search of the international and national literature revealed 53 studies that fit the time frame and study characteristics. Three analyses of these studies were undertaken: (a) features of the research method; (b) socio‐demographic characteristics of the subjects; and (c) components of environmental literacy assessed. Three charts were constructed to support these analyses; e.g., one for each analysis. For analysis (a), quantitative surveys were the most common method. For analysis (b), greater attention was paid to the age, grade level, gender and residence of participating students. For analysis (c), greater attention was paid to knowledge of ecology and natural history, and knowledge of environmental problems and issues, less attention was paid to components of affect, and very little attention was paid to socio‐political‐economic knowledge, cognitive skills and environmentally responsible behavior. 相似文献
