Bu çalışmanın amacı, fen bilimleri öğretmen adaylarının biyoteknoloji, genetik mühendisliği ve klonlama kavramlarına yönelik algılarını ve algısal değişimlerini incelemektir. Bu amaçla, …… Üniversitesi’nde öğrenim gören 119 öğretmen adayına 3. sınıf ve 4. sınıfta olmak üzere, iki kez Kelime İlişkilendirme Testi (KİT) uygulanmıştır. Nitel araştırma yöntemlerinden olgu bilim desenine göre tasarlanan çalışmada, içerik analizi tekniği kullanılmıştır. KİT uygulaması sonucunda anahtar kavramlar ile ilişkili verilen cevaplardan oluşan bir frekans tablosu hazırlanmıştır. Bu tabloya göre fen bilimleri öğretmen adaylarının bilişsel yapılarını ortaya çıkaran kavram ağları çizilmiştir.Araştırmada ilgili kavramlara yönelik verilen derslerin fen bilimleri öğretmen adaylarının biyoteknoloji, genetik mühendisliği ve klonlama kavramları ile ilgili bilişsel yapılarını geliştirdiği belirlenmiştir. Çalışmada dersleri aldıktan sonra verilen kavramlarla ilişkili elde edilen kelimelerin hem niteliksel hem de niceliksel olarak arttığı ve kavram yanılgılarının azaldığı sonucuna ulaşılmıştır. Sonuçlarımıza göre, fen bilimleri öğretmen adaylarının lisans derslerinde biyoteknoloji uygulamaları konularına daha çok yer verilmesi önerilmektedir.
The purpose of the research is to examine preservice science teachers' perceptions and perceptional changes towards biotechnology, genetic engineering and cloning concepts. For this purpose, the Word Association Test (WAT) was applied two times to 59 preservice science teachers, who are studying at Inonu University, in the third degrees of 2017-2018 school year and the fourth degrees of 2018-2019 school year. The study was designed based on one of the qualitative research method named as phenomenology and analyzed with content analysis. A frequency table consisting of key concepts and answer words was prepared as a result of the WAT. According to this table, concept networks that reveal the cognitive structures of preservice science teachers are drawn. In the study, it was determined that preservice science teachers' cognitive structures related to biotechnology, genetic engineering and cloning concepts developed with the routine courses related biotechnology. The results showed that the preservice teachers' prior knowledge widened to the large area that was not related to the concepts and, they produced more responses in the after taking related courses. In addition, it was concluded that the preservice teachers' misconceptions decreased and they perceived the relationshipsihp between concepts as a network after taking the related courses. The importance of the research results in terms of biotechnology/science education and using WAT as an educational tool were criticized.
