Okul öncesi eğitimi öğretmen adaylarının empatik eğilim düzeyleri ile düşünme stilleri arasındaki ilişkinin belirlenmesi

The main objective of this study is to determine the relationship between the empathic tendency levels and thinking styles of preschool teacher candidates. In this study that was patterned with the relational survey model, the data were collected through the use of the personal information form, empathic tendency scale developed by Dökmen (1988) and the thinking styles inventory which was developed by Sternberg and Wagner (1992) in accordance with the Mental Self-Management Theory and was both shortened and adapted into Turkish by Buluş (2006). The sample group of the study consisted of 209 teacher candidates who were selected through the suitable sampling method from Pamukkale University Faculty of Education Department of Primary Education and Preschool Education in the school year of 2014-2015. “Ninety percent” of the teacher candidates who participated in the study were female (n=188) and 10% were male (n=21). The data acquired in the study were analyzed by using the statistical methods of percentage, frequency, arithmetic mean, t-test, ANOVA, Pearson Product-Moment Correlation Coefficient and Linear Regression with the help of the SPSS package software. As a result of the study, the empathic tendency levels of preschool education teacher candidates were presented as a mean value ( X =70.50) and it was concluded that variables like gender, class levels and age did not significantly affect the empathic tendency level. Regarding the thinking styles, on the other hand, it was determined that they mainly preferred the legislative and executive styles and merely the conservative style. It was also determined that some subscales of thinking styles significantly differentiated according to gender, class levels, and age. Furthermore, statistically significant correlations were obtained in some subscales of empathic tendency and thinking styles. Accordingly, the acquired results were discussed with the results of other studies in literature and some recommendations were made

Eco-tourism opportunities for rural development at Yıldız Mountains

Kırklareli’nin Yıldız dağlarında kalan yerleşim yerleri sosyo-ekonomik yönden Trakya bölgesinin diğer yörelerine göre daha az gelişmiştir. Köylülerin büyük bir bölümü ormancılık işlerinde çalışmakta ve orman ürünleri konusunda faaliyet göstermektedirler. Ancak kıyıya yakın olan yerleşim yerlerinde yaşayan bölge halkı ise, bu faaliyetler yanında balıkçılık ve yaz aylarında artan turizm aktiviteleri ile geçimlerini sürdürmektedir. Özellikle orman içi köylerde yaşayanların refah düzeyinin yükseltilmesi, bölgenin sürdürülebilir kalkınması açısından oldukça önemlidir. Bölgenin sahip olduğu zengin doğal kaynakları (flora, fauna) kırsal kalkınmanın sağlanmasına önemli katkılar sağlayabilir. Yazın Temmuz ve Ağustos aylarında denize girme amacıyla gelenler dışında bölgede çarpıcı bir hareketlilik yaşanmamaktadır. Bu aylar dışında da av turizmi, doğa yürüyüşleri, fotoğrafçılık, kongre turizmi, konferans vb. aktivitelerle bölge çekim merkezi haline getirilebilir. Yıldız dağlarında bulunan orman köylerinin kırsal kalkınmasının sağlanabilmesi için ekoturizm ağırlıklı turizm hareketleri geliştirilebilir. Bu bağlamda aile işletmeciliğine dayalı turizm ve ev pansiyonculuğunun geliştirilmesi önerilebilir. Köylerdeki uygun evlerin pansiyon olarak kullanılması için bölgede yaşayanlara eğitim ve kredi desteği verilmelidir. Bölgenin tanıtılması ve her mevsim ziyaretlerin yapılması teşvik edilmelidir. Bunun için festivaller düzenlenebilir, bölgede yapılan el sanatları ve manda yoğurdu, organik bal vb. yerel gıdalar tanıtılabilir. Bölgenin önemli bir turizm çekim merkezi olarak tanıtımının yapılabilmesi için, bölgede üretilen alabalık yanında, kum zambağı gibi bitki türlerinden ve longoz ormanlarındaki birçoğu endemik olan bitkilerden de yararlanılabilir. Ayrıca bölgede önemli bitki türlerinin yanında Dupnisa mağarası gibi doğal koruma alanları da bulunmaktadır. Diğer taraftan çalışmaları tamamlanan “Yıldız Dağları Biyosfer Projesi”nin sonuçları da bu bölgenin sürdürülebilir kalkınması için bir rehber oluşturabilir. Bu bölgenin bir kısmının UNESCO tarafından “Biyosfer Alanı” ilan edilmesi durumunda, marka yaratılması suretiyle yerel halkın geçim kaynaklarının genişletilmesi ve geliştirilmesi olanağı yaratılacağı düşünülmektedir.Yıldız Mountains area of Kırklareli is comparatively less developed than the rest of the Trakya region. Majority of the villagers are involved with forest related jobs but at the coastal areas the villagers are also involved with tourism and fishing. An increased level of income is crucial for the sustainable growth of the region especially for the villages which are not on the coast. Vast variety of natural resources that the region has may contribute to the rural development of the region. The area which is mostly idle except the summer months and can be a centre for attraction for activities such as hunting, hiking, congress tourism, photographing. Eco tourism centred economic activities can be developed for rural development of the area. Suitable homes in the area can be encouraged to become family hotels via financial and training supports. The region has to be promoted to attract visitors all around the year. Festivals can be a very suitable tool for the promotion of the region, hand crafts, local cuisine and such can also be used for the promotion of the region as well. The region also hosts Dupnisa cave which is a natural conservation area. “Yıldız Mountains Biosphere Project” can also be considered as a guide for the sustainable development of the region. Declaration of the region as “Biosphere area” by UNESCO may help the region to develop and increase its’ level of income by creating a brand recognitio
