The aim of this study was to investigate the effects of aesthetic education on the development of aesthetic judgment of 6 year-old children. The sample of the study comprised 77 children selected randomly from state run primary schools from various socioeconomic levels in Ankara. The experiment group consisted of 22 children, the placebo group of 23 children and the control group of 32 children. The experiment group received an aesthetic education program, the placebo group was offered a placebo education and the control group did not take any education. The Taylor–Helmstadter Pair Comparison Scale of Aesthetic Judgment was used to measure the aesthetic judgments of children. The findings of the study show that there is a significant difference in the aesthetic judgments of male children in the experiment group who received aesthetic education (p < .05). Moreover, it found that the educational and socioeconomic levels of parents did not have any effects on the aesthetic judgments of children (p > .05).  相似文献

The design approaches of new exterior additions to historic buildings have been among the ongoing debates in the field of architectural conservation. The aim of this study is to develop an assessment method, which can be used to determine the compatibility in architectural expression of the new addition in relation to the characteristics of a historic building. This method is based on the architectural analysis, which includes environmental relations, building-lot relations, mass relations and the facade composition of the historic building both before and after the new addition in relation to the value of a historical building. In this study, a selected group of historic buildings in ?zmir, Turkey with new exterior additions was analysed with regard to their exterior architectural characteristics in order to evaluate the compatibility of the new addition, by employing the use of contemporary conservation principles. The importance of this study is to guide architects to form the basis of a decision for developing an integrated approach in designing new additions in the course of the actual design process. On the other hand, the proposed method can be evaluated as a contribution to the emerging field of heritage impact assessments as well as scientific assistance to local governments to criticize specific projects of cultural heritage assets submitted for appraisal. Analysis results showed that the value of the historic building should first clearly be identified and a new addition should bear the identity of its own period. However, instead of altering the scale or form of the historic building, a new addition should complement and contribute to the sense of proportion, disposition and historical pattern.  相似文献

Introductıon:

We evaluated the effect of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin.

Materials and methods:

In this multi-step experimental study, percent dilution ratios (PDRs) and final heparin concentrations (FHCs) were calculated by gravimetric method for determining the effect of syringe volume (1, 2, 5 and 10 mL), needle size (20, 21, 22, 25 and 26 G) and sample volume (0.5, 1, 2, 5 and 10 mL). The effect of different PDRs and FHCs on blood gas and electrolyte parameters were determined. The erroneous results from nonstandardized sampling were evaluated according to RiliBAK’s TEa.

Results:

The increase of PDRs and FHCs was associated with the decrease of syringe volume, the increase of needle size and the decrease of sample volume: from 2.0% and 100 IU/mL in 10 mL-syringe to 7.0% and 351 IU/mL in 1 mL-syringe; from 4.9% and 245 IU/mL in 26G to 7.6% and 380 IU/mL in 20 G with combined 1 mL syringe; from 2.0% and 100 IU/mL in full-filled sample to 34% and 1675 IU/mL in 0.5 mL suctioned sample into 10 mL-syringe. There was no statistical difference in pH; but the percent decreasing in pCO2, K+, iCa2+, iMg2+; the percent increasing in pO2 and Na+ were statistical significance compared to samples full-filled in syringes. The all changes in pH and pO2 were acceptable; but the changes in pCO2, Na+, K+ and iCa2+ were unacceptable according to TEa limits except fullfilled-syringes.

Conclusions:

The changes in PDRs and FHCs due nonstandardized sampling in syringe washed with liquid heparin give rise to erroneous test results for pCO2 and electrolytes.  相似文献

This study adapted the Mathematics Anxiety Rating Scale-Short Version (MARS-SV) into Turkish and investigated the validity and reliability of the adapted instrument. Twenty-five bilingual experts agreed on the language validity, and 49 Turkish language experts agreed on the conformity and understandability of the scale’s items. Thirty-two subject matter experts’ responses provided evidence for content validity. Finally, 475 college students (51.58% men) responded to the adapted scale. Based on the existing literature, several models were specified and estimated. Confirmatory factor analyses showed that only five-factor model provided fit to the data (all fit indices exceeded 0.90). Standardized factor loadings were found all positive, significant, and ranged from 0.40 to 0.78. Factors are named as the Mathematics Test Anxiety, Course Anxiety, Computation Anxiety, Application Anxiety, and Social Anxiety. All subscales were significantly correlated with the total scale score as well as among themselves. It was concluded that the adapted scale measures the construct of mathematics anxiety in Turkish college student populations.  相似文献

The purpose of this study is to profile future science teachers’ understandings of current environmental issues in the context of an education reform in Turkey. Knowledge base and understandings of elementary and secondary prospective science teachers about biodiversity, carbon cycle, global warming and ozone layer depletion were targeted in the study. Questionnaire surveys developed for this purpose were adapted and used in this investigation. The questionnaires were administered to 360 participants in six universities. Analysis involved frequencies, percentages and comparing means for students majoring in elementary and secondary science teaching. Analysis of variance for differences among majors and responses to different issues are also included. Findings are compared and contrasted with the previous research in other countries. The study has implications for the prospective preparation of teachers and the future of environmental literacy movement in Turkey.  相似文献

The study examined: (a) the role of phonological, grammatical, and rapid automatized naming (RAN) skills in reading and spelling development; and (b) the component processes of early narrative writing skills. Fifty-seven Turkish-speaking children were followed from Grade 1 to Grade 2. RAN was the most powerful longitudinal predictor of reading speed and its effect was evident even when previous reading skills were taken into account. Broadly, the phonological and grammatical skills made reliable contributions to spelling performance but their effects were completely mediated by previous spelling skills. Different aspects of the narrative writing skills were related to different processing skills. While handwriting speed predicted writing fluency, spelling accuracy predicted spelling error rate. Vocabulary and working memory were the only reliable longitudinal predictors of the quality of composition content. The overall model, however, failed to explain any reliable variance in the structural quality of the compositions.  相似文献
