PROBLEME DAYALI ÖĞRENME YAKLAŞIMI ĐLE GELENEKSEL ÖĞRETĐMĐN KARŞILAŞTIRILMASI: BĐR META-ANALĐZ ÇALIŞMASI

Öz

Bu araştırmada probleme dayalı öğrenme (PDÖ) yaklaşımının etkililiğini geleneksel yöntem ile karşılaştıran çalışmaların meta-analizi yapılmıştır. Probleme dayalı öğrenmenin akademik başarı üzerindeki etki büyüklüğü benzer konularda birbirinden bağımsız ve çok sayıda yapılmış çalışmaların verilerini analiz ederek genel bir yargıya varma yöntemi olarak tanımlanan meta-analitik yöntem ile hesaplanmıştır. Bu amaçla 2006-2013 yılları arasında ilgili konuya ilişkin yapılan araştırmalardan belirlenen dâhil edilme kriterlerine uygun 26 adet deneysel çalışma meta-analiz için seçilmiştir. Araştırma sonucunda PDÖ’nün akademik başarıya olan etki büyüklüğü 1.302 olarak hesaplanmıştır. Bu değerin Thalheimer ve Cook (2002)’un ayrıntılı düzey sınıflamasına göre çok geniş etkiye sahip olduğu anlaşılmıştır. Ayrıca meta-analiz sonuçları PDÖ kullanımının geleneksel öğretim yöntemine göre akademik başarı açısından olumlu etki oluşturduğunu göstermiştir.Key Words:Problem-based learning, academic achievement, traditional method, meta-analysis, effect size.

Anahtar Kelimeler

• Probleme dayalı öğrenme, akademik başarı, geleneksel öğretim, meta-analiz, etki büyüklüğü.

A META-ANALYSIS STUDY COMPARING PROBLEM BASED LEARNING WITH TRADITIONAL INSTRUCTION

Öz

In this study, the efficiency of Problem-Based Learning (PBL) was compared with traditional methods. The effect size (ES) of PBL on academic achievement was calculated by using a meta-analytic method defined as drawing a general conclusion by analysing the data from a range of independent studies of similar subjects. Thus, 26 experimental studies were selected, which comply with the inclusion criteria determined with the help of research carried out between 2006 and 2013. The effect size of PBL on academic achievement was calculated as 1.302. According to Thalheimer and Cook’s (2002) detailed level calculation,this value has a very large effect. The results of meta-analysis demonstrate that compared to traditional instruction methods, PBL has a positive effect on academic achievement.

Anahtar Kelimeler

• Problem-based learning, academic achievement, traditional method, meta-analysis, effect size.
