Laboratuvar Uygulamalarında Çöktürme Titrasyonları Konulu Senaryoların Etkisi

Öz

Araştırmada Genel Kimya III (Analitik Kimya) dersi “Çöktürme Titrasyonları” konusunda örnek-olaya dayalı laboratuvar uygulamalarının öğrencilerin akademik başarılarına etkisinin incelenmesi amaçlanmıştır. Çalışma grubunu bir üniversitenin Fen Bilgisi Öğretmenliği Programında okuyan ikinci sınıf öğrencileri oluşturmaktadır. Mevcut iki şubeden birisi deney (n=32), diğeri kontrol grubu (n=32) olarak rastgele seçilmiştir. Araştırma ön-test son-test kontrol gruplu yarı-deneysel desendir. Deney grubu öğrencileri örnek-olaya dayalı laboratuvar uygulamalarıyla, kontrol grubu öğrencileri ise öğretim programına uygun laboratuvar uygulamalarıyla dersi işlemiştir. Araştırmada çöktürme titrasyonları konusunda günlük yaşamla ilişkili iki örnek olay geliştirilmiştir. İlk örnek olayın konusu, havuz dezenfeksiyonunda aşırı klor gazının kullanımından dolayı zehirlenen bir gence, ikinci örnek olayın konusu ise tatlı su balığının deniz suyuna bırakılması sonucu balığın başına gelenlerin anlatılmasına dayanmaktadır. 11 Açık uçlu sorudan oluşan “Çöktürme Titrasyonları Başarı Testi” veri toplama aracı olarak kullanılmıştır. Testteki açık uçlu sorulara verilen yanıtlar puanlanarak nicel veriler elde edilmiş ve bağımsız ve bağımlı gruplar için t-testi ile analiz edilmiştir. Açık uçlu sorular ayrıca içerik analiziyle analiz edilmiştir. Çalışma sonuçları, örnek-olaya dayalı laboratuvar uygulamalarının öğrencilerin çöktürme titrasyonları (arjantometrik yöntemler) konusunda tam anlamalarını ve akademik başarılarını arttırdığını göstermiştir.
