Bu çalışmanın amacı kimya öğretmen adaylarının metalik yapı ve metalik bağ hakkındaki zihinsel modellerinin belirlenmesidir. Örneklem, Eğitim Fakültesi Kimya Öğretmenliği Programına devam eden 64 kimya öğretmen adayından oluşmaktadır. Tüm katılımcılar hem Genel Kimya hem de Anorganik Kimya dersleri sırasında metalik bağ teorileri ve metalik yapıyı görmüşlerdir. Veriler, açık uçlu iki soru içeren bir ölçekle toplanmıştır. İlk soruda. Kimya öğretmen adaylarından bakır metalinin yapısındaki bağı çizerek açıklamaları istendi. İkinci soruda, metalik bağın tanımı sorulmuştur. Veriler, araştırmacı tarafından fenomenografik analiz yöntemi kullanılarak analiz edilmiştir. Kimya öğretmen adaylarının metalik bağ ile ilgili nitel olarak farklı şekillerde düşündükleri ve öğrencilerin çoğunun zihinsel modellerinin basit olduğu ve bazılarının bağ teorilerinin melez modellerine sahip olduğu belirlenmiştir

In this study, it was aimed to identify the prospective chemistry teachers' mental models about the metallic structure and metallic bonding firstly. The second aim was that how the prospective chemistry teachers' conceptions about metallic bonding. The sample consisted of 64 prospective chemistry teachers who were drawn from the Chemistry Education department at the Education Faculty. All participants were taught the metallic bonding theories and metallic structure in both General Chemistry and Inorganic Chemistry courses. The data were collected by an instrument with two open-ended questions. In the first question, prospective chemistry teachers were asked to explain the bonding in the structure of the copper metal by drawing. In the second question, they were asked to define what the metallic bonding is. The analysis of PCTs' responses was based on the Phenomenographic method. It was revealed that prospective chemistry teachers thought about the metallic bonding in the qualitatively different ways and most of the students' mental models were simple, and some of them had hybrid models of the bonding theories
