The purpose of this research is to examine the effect of microteaching on teaching experiences of pre-service chemistry teachers. The research which was a one-group pretest-posttest design study was conducted with 31 pre-service chemistry teachers in a state university in Turkey in 2009-2010 fall semesters. The data of the research was collected by using self-evaluation, group evaluation, peer-evaluation, researchers' evaluations, observer evaluation together with students' self-reflective essays and feedback forms. The data obtained from this study shows that pre-service chemistry teachers lack skills related to teaching experience before applying microteaching. Also the results of this study show that microteaching contributed to the development of communication skills performance, illustrated talk performance, and process skill lesson performance of the pre-service teachers. Moreover, pre-service chemistry teachers realized the deficiencies in their chemistry teaching practices and overcame them, emphasized the relationship between chemistry and daily life more, became more aware of students' misconceptions about chemistry topics due to the microteaching technique.
Keywords:Microteaching, Teaching experience, Pre-service chemistry teacher.

ÖzetBu çalışmanın amacı, Fen Bilgisi öğretmen adaylarının iyonik ve moleküler çözünme konularındaki imajlarını belirlemek ve imajlar yoluyla alternatif kavramalarını ortaya koymaktır. Araştırmanın katılımcılarını 2011-2012 akademik yılının güz döneminde İç Anadolu Bölgesinde bir üniversitede öğrenim gören 107 Fen Bilgisi öğretmen adayı oluşturmaktadır. Nitel bir sürecin izlendiği araştırmada çözünme konusundaki kavramlarla ilgili çizim ve açıklama yaptıran çalışma yaprakları ve yarı yapılandırılmış görüşme formları veri toplama aracı olarak kullanıldı. Araştırma sonunda öğretmen adaylarının iyonik ve moleküler çözünme konusundaki imajlarının yetersiz olmasının yanında birçok alternatif kavrama sahip oldukları tespit edildi.Anahtar Kelimeler: İyonik çözünme, moleküler çözünme, imaj, zihinsel model, alternatif kavrama Abstract The purpose of this study is to determine pre-service science teachers' images about ionic and molecular dissolutions and to explore their alternative conceptions through images. 107 pre-service science teachers from a public university participated in this study in 2011-2012 academic year. In this qualitative design, worksheets that make teachers to draw and explain the concepts about dissolution and semi-structured interview forms were used as data collecting devices. The results of study showed that pre-service science teachers' images about ionic and molecular dissolutions are insufficient and they have various alternative conceptions about dissolution.
