    A Phenomenographic Study on the Concept of Nature and Alienation of Children from Nature
    (Turkish Education Assoc, 2015) Kahyaoglu, Mustafa; Yetisir, M. Ikbal
    It is very difficult to instill a concept and interpretation of nature and a sense of responsibility to protect nature in the minds of children who are increasingly becoming disconnected and alienated from it.. TheFailure to integrate learning environments with nature, despite the continuous increase in the integration between learning environments andmodern technology, is complicating the task of creating perception of nature and awareness in children concerning the problems of nature. This study aims at shedding light on the way the teachers who are responsible for the design of the educational environments, perceive the concept of nature and alienation of children from nature. The phenomenographic research design, which is one of the qualitative research methods, was used in this study. The sample of the study was selected using criterion sampling method, one of the purposive sampling methods. The participants of the study are 40 teachers, including 20 elementary school teachers and 20 science teachers, who are assigned to schools located in the center of Diyarbakir province and affiliated with the Provincial Directorate of National Education. 17 (42.5%) of these participants were female and 23 (47.5%) were male. The findings of the study revealed that the teachers interpret the concept of nature under three different categories: these are respectively physical/ visible features of nature, wholeness and function of nature and its importance for the human health. Consequently, inclusion of activities that have the contents of nature in the design of educational programs and relate to children who spend most of their time at school and design of learning environments with models, samples and visual tools which include contents of nature may make it easier for children to perceive and interpret nature.

    An Evaluation of Elementary Teacher Candidates' Environmental Approaches, Environmental Risk Perceptions and Environmental Behaviours
    (Elsevier Science Bv, 2012) Kaya, M. Fatih; Kahyaoglu, Mustafa; Birel, G. Firat
    The purpose of this research is to determine elementary teacher candidates' environmental approaches (environmental-based or human-based), environmental risk perceptions and environmental behaviours. Furthermore this research intend to determine if there is a significant difference in elementary teacher candidates' environment-centered or human-centered approaches, environmental risk perceptions and environmental behaviours according to the variables of gender and class, or not. The research was carried out with a total of 243 teacher candidates (131male and 112 female) from Elementary Department of Faculty of Education at Siirt University in Turkey. It was used the New Environmental Paradigms Scale, which was first time developed by Dunlap and Van Liere (1978) and revised by Dunlap et. al. (2000) and adapted into Turkish by Furman (1998), to determine the environmental approaches of the teacher candidates, the Environmental Risk Perceptions Scale, which was developed by Slimak and Dietz (2006) and adapted into Turkish by Altunoglu and Atav (2009), was used to determine the teacher candidates' perceptions of environmental risk and it was used Environmental Behaviour Scale, which was developed by Uzun and Saglam (2006), to determine their environmental behaviours. At the analysis of data; it was consulted from descriptive statistical techniques and Pearson Moment Correlation coefficient. In our research, it was calculated that the Cronbach alpha reliability coefficient of environmental approaches scale as .65, the scale of environmental risk perceptions as .93 and the scale of environmental behavior as .85. As a result of this research, it was found that the teachers candidates' environmental-centered approach mean score (M=4.21) is higher than human-centered approach mean score (M=3.35). Moreover, it was found that there is a significant and positive relation between the elementary teacher candidates' human-centered approaches, environmental risk perceptions (r=.41; p<0.01) and environmental behaviours (r=.20; p<0.01).

    (Chinese Center Disease Control & Prevention, 2012) Darcan, Cihan; Kahyaoglu, Mustafa
    Objective To study MIC value of 7 boron derivatives namely [Boric acid (H3BO3), Anhydrous Borax (Na2B4O7), Sodium Borate (NaBO2), Diammonium Tetraborate (NH4)(2)B4O7, Sodium Perborate (NaBO3), Boron Trioxide (B2O3), Potassium Tetraborate (K2B4O7)] on E. coli and P. aeruginosa and their effects on survival of bacteria in lake water and resistance against kanamycin antibiotic. Methods MIC values of Boron derivatives and antibiotic were studied by broth microdilution method. The effect of boron derivatives on survival of bacteria in lake water were also determined with plate count. Results Sodium perborate was determined as the most effective substance among the studied substances. Effectiveness increased as temperature increased. E. coli was more affected from P. aeruginosa in 8 mg/mL sodium perborate concentration in lake water. Moreover, it was determined that MIC value of kanamycin antibiotic decreased 200 times by especially treating P. aeruginosa with sodium perborate in lake water. However, it can be stated that this change in resistance did not arise from microorganisms. Conclusion Sodium perborate solution can be used supportedly in kanamycin antibiotic applications for P. aeruginosa. Future studies are necessary to explore the relation between sodium perborate and kanamycin which is effective on P. aeruginosa in lake water.

    The Relationship between Teacher Candidates' Environmental Risk Perceptions and Problem Solving Skills
    (Nesibe Aydin Education Inst, 2012) Kahyaoglu, Mustafa
    Problem Statement: Various environmental problems are related with wrong risk perception about the environment as well as insufficient interest, behavior, information and environmental perception. Although there are social concerns related with environmental problems, it can be seen that environmental problems have become a greater threat in time. People react to the threats they perceive. If their perceptions are not correct, their efforts for protecting society and environment may be misevaluated. The main goal of environmental education and risk communication can be summarized as making individuals and society understand and perceive the environment and environmental problems correctly (Hines, Hungerford and Tomera, 1986; Hungerford and Volk, 1990; Wilson, 1990; akt: Altunoglu and Atav; 2009). However, there are limited studies were encountered on teacher candidates' environmental risk perceptions and their problem solving skills during literature review. Purpose of the Study: The purpose of the study was to determine the relationship between elementary teacher candidates' environmental risk perceptions and their problem solving skills and answers were sought to the following questions: 1) What is the relationship between teacher candidates' environmental risk perceptions and their problem solving skills? 2) Is there a significant difference between teacher candidates' environmental risk perceptions and sub-dimensions of their problem solving skills and gender variable? 3) Is there a significant difference between teacher candidates' environmental risk perceptions and sub-dimensions of their problem solving skills and variable of the program they studied? 4) What is the relationship between teacher candidates' environmental risk perceptions and sub-dimensions of their problem solving skills? Method(s): The sample of research was teacher candidates from the elementary class and science programs of education faculty in Siirt University 204 students participated in the research study. In the research by Slimak and Dietz (2006) developed risk scale which consists of 24 items and adapted to Turkish by Altunoglu & Atay (2009) were used in order to collect information about environmental risk perception and problem solving skills inventory developed by Heppner and Peterson (1982) which consists of 35 items and adapted to Turkish by Sahin, Sahin & Heppner (1993). In order to understand the gathered data, besides the arithmetic mean and standard deviation of the variables, independent t-test and Pearson Moment Correlation Coefficient are used in the data analysis process. Findings and Results: The findings, obtained from the Pearson's moment correlation analysis to determine the relationship between teacher candidates' environmental risk perceptions and problem-solving skills. A positive significant relationship (r = .308, p < 0.01), at a moderate level, was determined between teacher candidates' environmental risk perceptions and problemsolving skills. Conclusions and Recommendations: When the relationship between teacher candidates' environmental risk perceptions and sub-dimensions of their problem solving skills were examined, it was identified that there was a positive significant relationship between their planned, considerate, self-confident, avoidant and evaluative approaches; however, it was found that there was a positive but not a significant relationship between teacher candidates' hasty approach and their environmental risk perceptions.
