Abstract (2. Language): 
The purpose of this study was to determine 9 th grade students’ levels of understanding and misconceptions about mitosis and meiosis. 25 open-ended questions related to mitosis and meiosis conceptions were administered to 139 9 th grade students. The results revealed that students had difficulties about the basic processes in mitosis and meiosis, the chromosome behaviours and some misconceptions because of the widespread lack of understanding of DNA, chromatid, chromosome, homologous chromosome, haploid-diploid cell concepts and the relationships between these concepts.
Abstract (Original Language): 
Çalışmanın amacı, lise 1.sınıf öğrencilerinin mitoz ve mayoz bölünme konularını anlama düzeylerini ve bu konularla ilgili sahip olduklarıkavram yanılgılarını belirlemektir. Bu amaçla, mitoz ve mayoz bölünme konularıhakkında 25 açık uçlu soru geliştirilmişve 139 lise 1.sınıf öğrencisine uygulanmıştır. Sonuçlar, öğrencilerin DNA, kromozom, kromatit, homolog kromozom, haploid ve diploid hücre gibi temel kavramlarıve aralarındaki ilişkileri yeterince anlayamadıklarını, bu duruma bağlı olarak mitoz ve mayoz bölünme süreçlerindeki temel olayları, kromozom davranışlarını da anlamakta güçlük çektiklerini ve kavram yanılgılarına sahip olduklarını göstermiştir.
