Bu çalışmada, lisans ve lisans üstü programlarındaki öğrencilere otoprotoliz denge  sabiti ve bu sabite iyonik şiddetin ve sıcaklığın etkisi ile ilgili kavramları öğretmeye  yardımcı olacak yapılandırıcı öğrenme teorisine dayalı bir laboratuvar aktivitesi  hazırlanmıştır. Gösteri, rehberli sorgulama, kavram oluşturma ve uygulama  aşamalarından oluşturulan aktivite 2001-2002 öğretim yılında G.Ü. Gazi Eğitim  Fakültesi Kimya Eğitimi Anabilim Dalı 4. Sınıf öğrencilerinden rasgele seçilen 22  öğrenciye uygulanmıştır. Aktivitenin etkisi araştırmacıların sınıf içi gözlemleri, işlem  yapraklarının incelenmesi ve laboratuvar raporlarının değerlendirilmesiyle kalitatif  olarak araştırılmıştır. Aktivitenin, öğrencilerin derse karşı ilgi ve tutumlarını artırdığı,  motivasyonlarını pozitif yönde etkilediği, derse aktif katılIn this study, a laboratory activity based on constructivist learning approach was  prepared for teaching undergraduate and graduate students autoprotolysis equilibrium  constant and effect of ionic strength and temperature to this constant. The activity that  consisted of demonstration, guided inquiry, concept generation and application phases  was carried out with twenty-two students randomly selected from senior students in  Gazi University, Faculty of Gazi Education, Department of Chemistry Education during  the terms of 2001-2002. The effect of activity was qualitatively investigated with in-class  observation of researchers, examination of worksheets and evaluation of lab reports.
