The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers’ teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers’ beliefs about GM foods (content knowledge, risk perceptions, moral beliefs, and religious beliefs) and their teaching efficacy beliefs about this topic constitute a belief system, and these beliefs are interrelated due to core educational beliefs. We used an exploratory mixed design to test this model. We developed and administered specific questionnaires to probe the belief system model. The sample for the quantitative part of this study included 441 preservice science teachers from eight universities. We randomly selected eight participants in this group for follow-up interviews. The results showed that preservice science teachers held moderately high teaching efficacy beliefs. Learning and teaching experiences, communication skills, vicarious experiences, emotional states, and interest in the topic were sources of this efficacy. In addition, content knowledge and risk perceptions were predictors of teaching efficacy. We believe that epistemologies based on traditional teaching and the values attached to science teaching are the core beliefs that affect the relationship between predictor variables and teaching efficacy.  相似文献   

Students and school characteristics related to elementary school students' views of the nature of science

The purpose of this study is to investigate student- and school-level factors that help to explain the difference in the nature of science (NOS) views. Overall, the design of this study is correlational. The sample consisted of 3062 students enrolled in the sixth, seventh, and eighth grades of elementary schools in Turkey. A hierarchical linear modelling was selected as a modelling technique. This study has established the importance of the student's socioeconomic background, learning approaches undertaken, self-efficacy, and motivational goals in the formation of their NOS views. The findings reveal that quality of both the physical infrastructure of schools and the educational resources in schools, parent educational levels, student achievement, self-efficacy, experience of meaningful learning, and learning goal orientation are positively related to different dimensions of student NOS views. Additionally, performance goal orientation and rote learning approaches have a negative relationship with different dimensions of student NOS views.  相似文献   

教师教学效能感及其相关因素研究   总被引：79，自引：0，他引：79

教师心理研究的一个重要目的在于提高教师素质,而教师教学效能感等因素是影响教师素质的重要方面。教师教学效能感是教师在教学活动中对其能有效地完成教学工作、实现教学目标的一种能力的知觉与信念,并与教学监控能力、教学策略和教学行为等因素相关。教师教学效能感及其相关因素的研究为正在实施的“跨世纪园丁工程”提供了一个新视野  相似文献

Detection of preanalytical errors in arterial blood gas analysis     

Serap uhadar  Hayat zkanay-Yrük  Mehmet Kseolu  Kaan Kat&#x;rc&#x;olu 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2022,32(2)

IntroductionBlood gas analysis (BGA) is an essential test used for years to provide vital information in critically ill patients. However, the instability of the blood gases is a problem. We aimed to evaluate time and temperature effects on blood gas stability.Materials and methodsArterial blood was collected from 20 patients into syringes. Following BGA for baseline, syringes were divided into groups to stand at 4°C and 22°C for 30, 60, 90, 120 minutes. All were tested for pH, partial pressure of carbon dioxide (pCO₂), partial pressure of oxygen (pO₂), oxygen saturation (sO₂), oxyhemoglobin (O₂Hb), sodium, potassium, glucose, lactate, oxygen tension at 50% hemoglobin saturation (p50), and bicarbonate. A subgroup analysis was performed to detect the effect of air on results during storage. Percentage deviations were calculated and compared against the preset quality specifications for allowable total error.ResultsAt 4°C, pO₂ was the least stable parameter. At 22°C, pO₂ remained stable for 120 min, pH and glucose for 90 min, lactate and pCO₂ for 60 min. Glucose and lactate were stable when chilled. Air bubbles interfered pO₂ regardless of temperatures, whereas pCO₂ increased significantly at 22°C after 30 min, and pH decreased after 90 min. Bicarbonate, sO₂, O₂Hb, sodium, and potassium were the unaffected parameters.ConclusionsCorrect BGA results are essential, and arterial sample is precious. Therefore, if immediate analysis cannot be performed, up to one hour, syringes stored at room temperature will give reliable results when care is taken to minimize air within the blood gas specimen.  相似文献   

Distance education in the Turkish secondary education system     

Feyzi Uluğ 《Educational technology research and development : ETR & D》1994,42(4):116-119

Conclusion The OHS, although newly established, has created great interest among all the media. It is evident that this interest will continue to increase. This means that the OHS filled a very important niche in the educational structure. It is believed that most of the problems faced at the OHS will be solved in a very short time, and new ways are continually being sought. But at the moment it is necessary to remember that high quality should be maintained, instead of focusing on quantity. This motive prescribes that educational technologies should be transferred to the educational system. To accomplish this, ways should be found to increase the finances of the OHS, and governmental support should be increased to improve the technical quality. In addition, it is necessary to change the regulation of the OHS as a project of the FRTED to allow the OHS to function independently. The resulting organizational structure should be evaluated effectively. Also, it is necessary to improve the structural effectiveness of local representatives of the OHS for authorization and duties. At the same time, it is essential to use the local high schools to provide face-to-face education for distance education students. If the critics are correct, the OHS will be an original secondary-school-level distance education institute and can be a good example for other countries.  相似文献   

Women’s Sport as a Symbol of Modernity: A Case Study in Turkey     

Gertrud Pfister  Ilknur Hacısoftaoğlu 《国际体育史杂志》2016,33(13):1470-1482

Abstract

Turkey has a distinctive position with regard to its geography and history among Muslim countries. Particular features are its secular system and far reaching modernization processes particularly with respect to the ‘emancipation’ of women. The aim of this paper is to describe and analyze sport and body politics as part of the modernization processes in Turkey and to explore in particular the multiple roles of different groups of women in the reforms initiated by the Turkish Governments. A focus will be on the intersecting influences of gender and social class. The famous archaeologist Halet Çambel will be used as an example of the ‘modern’ woman who embodied reformist ideologies. Çambel was the daughter of an elite family; she was born in Berlin where her father was an attaché at the Turkey embassy. She studied in France and participated in the Olympic Games in 1936. She and another Turkish fencer were the first women from a Muslim country to participate in the Olympic Games. Later she became the most famous archaeologist in Turkey and she stayed physically active all her life. In particular, horse riding became a favourite activity as she travelled to archaeological sites on horseback.  相似文献
