Developing a sound understanding about the concept of ionic bond is fundamental to subsequent learning of various other topics related to this concept in chemistry Any misconception that students harbour about these concepts will impede their further learning The purpose of this study is to determine misconceptions held by high school chemistry students and prospective chemistry teachers about ionic bonding and to reveal that what kind of differences and similarities these misconceptions show according to the educational level and to present suggestions in the light of the findings obtained from the research With this aim a two tier true false diagnostic test is prepared making use of the literature and administered to a random sample of total of 120 students attending 1st 2nd and 3rd class of a regular high school in Malatya and 24 prospective chemistry teachers in the last year of their teacher education in a university in Turkey It was determined from the analysis of the results that high school students held similar misconceptions at all educational levels and surprisingly prospective chemistry teachers also held many misconceptions related to ionic bond concept Besides it was seen that most of these misconceptions were same or similar as to those held by high school students Based on these results some suggestions were made about teaching the concept of ionic bonding at secondary and undergraduate education level

Anahtar Kelimeler

Lise Öğrencileri ve Kimya Öğretmen Adaylarının İyonik Bağ Kavramına İlişkin Yanılgıları

Öz

İyonik bağ kavramının doğru anlaşılması, kimyada bu kavramla ilişkili çeşitli diğer konuları öğrenmede
önemlidir. Öğrencilerin bu kavramla ilgili taşıdıkları herhangi bir kavram yanılgısı sonraki öğrenmelerini
olumsuz etkileyecektir. Bu araştırmanın amacı, lise öğrencilerinin ve kimya öğretmen adaylarının iyonik bağ
kavramına ilişkin yanılgılarını saptamak ve bu yanılgıların öğrenim düzeylerine göre ne gibi farklılıklar ve
benzerlikler gösterdiğini ortaya çıkararak elde edilen bulgular doğrultusunda öneriler geliştirmektir. Bu
amaçla, hazırlanan iki aşamalı bir Doğru-Yanlış Tanı Testi Malatya’daki bir düz lisenin 1., 2. ve 3. sınıflarına
devam eden toplam 120 öğrenciye ve bir üniversitenin 24 kimya öğretmenliği son sınıf öğrencisine
uygulanmıştır. Araştırma sonucu elde edilen bulguların analizinden, lise öğrencilerinin hemen her düzeyde
benzer yanılgılara sahip olduğu ve şaşırtıcı bir şekilde kimya öğretmeni adaylarının da çok sayıda yanılgıya
sahip olduğu belirlenmiştir. Ayrıca bu yanılgıların birçoğunun lise öğrencilerinde tespit edilen yanılgılarla
aynı veya onlarla benzer olduğu da görülmüştür. Bu sonuçlara dayalı olarak iyonik bağ kavramının
ortaöğretimde ve lisans düzeyinde öğretimine ilişkin bazı önerilerde bulunulmuştur.
