ORTAOKUL MATEMATİK ÖĞRETMENLERİNİN ORAN VE ORANTI KONUSUNDA ALAN VE ÖĞRETME BİLGİSİ

Bu çalışmada ortaokul matematik öğretmenlerinin alan ve öğretme bilgilerinin ortaya konulması amaçlanmıştır. Bu amaçla araştırmada nitel araştırma desenlerinden çoklu durum çalışması benimsenmiştir. Araştırma, devlet ortaokulunda görev yapmakta olan 36 ortaokul matematik öğretmeni ile yürütülmüştür. Araştırmada veri toplama aracı olarak araştırmacı tarafından hazırlanan 9 yarı yapılandırılmış sorunun yer aldığı görüşme formu kullanılmıştır. Çalışmanın verileri betimsel analiz yolu ile analiz edilmiştir. Verilerin analizi sonucunda öğretmenlerin konuya giriş stratejileri, öğretimde ilişkilendirme bilgileri, temsil kullanma ve problem çözme stratejileri, öğrencilerin öğrenme stilleri ve öğretimi planlama bilgileri incelenmiştir. Çalışmadan elde edilen sonuçlar doğrultusunda, öğretmenlerin oran-orantı öğretimine girişte günlük hayatla ilişkili örnek durumlar vermeyi tercih ettikleri fakat öğrencilerin ön bilgilerini ortaya çıkarmada yetersiz kaldıkları görülmüştür. Öğretimde ilişkilendirme konusunda ise öğretmenlerin orantı-orantı konusunun günlük hayat ve diğer disiplinlerle ilişkisinin farkında oldukları fakat öğretimlerinde ilişkilendirmeye dayalı uygulamalar gerçekleştirmedikleri görülmüştür. Öğretmenlerin oran-orantı öğretiminde öğretimini zenginleştirme ve anlamlandırma amacıyla kullanılan çoklu temsillere yönelik bilgi sahibi oldukları bunun yanı sıra öğretim sürecinde en çok kullanıldıkları temsilin ise sözel problem olduğu görülmüştür. Öğretmenlerin sözel problemlerde kullanılabilecek problem çözme stratejilerine ait bilgilerinin kısıtlı olduğu görülmüştür. Öğretimi planlamada ise öğrencilerin bireysel özelliklerine yönelik öğretmenlerin yetersiz bilgiye sahip oldukları sonucuna ulaşılmıştır.
