Abstract

Bu çalışmanın amacı, örnek olay ve örnek-olaya dayalı öğrenmeye ilişkin öğrenci görüşlerini araştırmaktır. Örnek olay, Analitik Kimya Laboratuarı dersi suların sertliğinin belirlenmesi deneyinde etilen diamin tetra asetik asit bileşiği (EDTA) ile metal iyonlarının kompleks oluşum reaksiyonlarına dayalı kompleks oluşum titrasyonuyla ilgili olarak hazırlanmıştır. Bu betimleyici çalışmanın örneklemi,  İzmir’de bir üniversitede Kimya Öğretmenliği bölümünde okuyan ikinci, dördüncü ve beşinci sınıf öğretmen adaylarından (N=23) (20–23 yaşlar arasında) oluşmuştur. ‘Yapılandırılmış Görüşme Formu’ veri toplama aracı olarak kullanılmıştır. Veriler, nitel analiz tekniklerinden içerik analiziyle analiz edilmiştir. Elde edilen verilere göre; öğrenciler örnek-olaya dayalı öğrenme yönteminin kapsamlı ve uygun olduğunu belirtmişlerdir. Ayrıca hazırlanan örnek olayın araştırma yapma isteklerini ve motivasyonlarını arttırarak öğrenmelerini eğlenceli hale getirdiğine dair olumlu görüşlerde de bulunmuşlardır.

Development a Material Used in Case-Based Learning for Analytical Chemistry Laboratory Application and Students’ Views

Abstract

The objective of this study is to investigate students’ views about the case study and case-based learning (CBL). The case study is prepared concerning the complex formation titration based on ethylene diamine tetra acetic acid compound (EDTA) and complex formation reaction of metal ions and the experiment of hardness determination in water in the Analytical Chemistry Laboratory course. The sample of this descriptive study consists of 2nd, 4th and 5th grade student teachers (N=23) (ages between 20-23 years-old) studying in the department of Chemistry Teaching at a university in Izmir. ‘Structured Interview Form’ was used as data col-lection tool. The data were analyzed via content analysis, which is a qualitative analysis technique. According to the data obtained; the students stated that the CBL method was comprehensible and convenient. In addition, they had also positive views that the case study being prepared was an entertaining study building up the desire for investigation and motivation.
