Abstract
Doğa eğitimlerin temel amacı öğrencilerin sürdürülebilir bir gelecek ve yaşanabilir bir çevre için doğayı tanımalarına ve anlamalarına yardımcı olacak, bireyleri doğayla bütünleştirecek bir eğitim vererek yaşadığı dünyanın önemini kavratmaktır. Bu açıdan ekoloji temelli doğa eğitimleri uygulanması ve sonuçlarının değerlendirilmesi oldukça önemlidir. Bu çalışmanın amacı, doğa temelli eğitimin, ilköğretim 7. ve 8. sınıf öğrencilerinin çevresel tutum ve akademik başarıları üzerindeki etkilerini araştırmaktır. Bu bağlamda çalışmada tek grup öntest-sontest deney tasarımı kullanılmıştır. Çalışma grubu tabakalı örneklem yöntemi ile belirlenmiştir. Bu kapsamda dezavantaj durumlarına göre 2015-2016 eğitim-öğretim yılında Kastamonu ilinde bulunan yedinci ve sekizinci sınıf düzeyinde öğrenim gören 47 yedinci ve sekizinci sınıf öğrencisi seçilmiş ve öğrenciler çalışmaya katılmaya gönüllü olmuştur. Veri toplama aracı olarak çevresel bilgi testi ve çevreye yönelik tutum ölçeği kullanılmıştır. Veriler bağımlı örnekler için t-testi ile analiz edilmiştir. Öğrencilerin eğitim sonucunda bilgi düzeylerinde önemli derecede bir artış olduğu ve tutumlarında da olumlu yönde değişim gerçekleştiği tespit edilmiştir. Bu bulgulara göre doğa eğitiminin amacına hizmet ettiği ve yaygınlaştırılması gerektiği sonucuna ulaşılmıştır.

Abstract
The main purpose of nature education is to help students to recognize and understand nature for a sustainable future and a liveable environment, to teach the importance of the world in which they live by providing education that integrates individuals with nature. In this respect, it is very important to implement nature education and to evaluate the results. The purpose of this study was to investigate the effects of nature education on the environmental attitude and academic achievement of the primary schools' 7th and 8th grade students. In this context, single group pretest-posttest experimental design was used in the study. The study group was determined by the stratified sampling method. In this context, 47 seventh and eighth grade students in the province of Kastamonu in the 2015-2016 academic year were selected according to their disadvantages and volunteered to participate in the study. As a data collection tool, environmental knowledge testing and attitude scale towards environment were used. The data was analyzed by t-test for dependent samples. As a result of the education, it was found that there was a significant increase in the knowledge level of the students and a positive change in their attitudes. According to these findings, it is concluded that nature education serves its purpose and should be expanded.
