Abstract

Given its importance, there is a perceived necessity to conduct an in-depth examination of studies on scientific reasoning skills and to create a guided map based on these examinations. This study aims to establish a general framework by examining national postgraduate theses related to scientific reasoning skills, revealing their current state, and updating any hidden or misunderstood skills. The research sample includes 74 national postgraduate theses from Türkiye, which are accessible through the National Thesis Center database of the Council of Higher Education (CoHE). These theses were analyzed in-depth using thematic content analysis, a qualitative research method. The examined national postgraduate theses were analyzed across 13 themes: “year”, “thesis type”, “field of education”, “research design/method model”, “type of experimental research”, “learning method”, “sample type”, “sample size”, “data collection methods/tools”, “data analysis technique”, “scientific reasoning skills included in the research”, “results” and discussions”, and “recommendations”. The findings revealed that most of these were written in 2019. The predominant thesis type was a master's thesis, and the most common field of education was mathematics education. The most frequent research design/method model was experimental, with quasi-experimental design being the most common type of experimental research. Middle school students were the most frequent sample type, with sample sizes most commonly ranging from 0-25. Tests were the most frequently used data collection methods/tools, and validity was the most employed data analysis technique. Argumentation-based learning was the preferred learning method. The most addressed scientific reasoning skill in the research was mathematical reasoning, specifically focused on mathematical reasoning skills. The results and discussions frequently highlighted improvements in students' scientific reasoning skills. The recommendations often advised researchers to develop applications aimed at enhancing scientific reasoning skills.

Bilimsel Muhakeme Becerileri ile İlgili Ulusal Lisansüstü Tezlerin Tematik İçerik Analizi

Abstract

Bilimsel muhakeme becerileri hakkında yapılan çalışmaların derinlemesine incelenmesinin ve bu incelemeler sonucunda yol gösterici bir haritanın oluşturulmasının gerekliliği düşünülmektedir. Bu çalışmada, bilimsel muhakeme becerisi ile ilgili ulusal lisansüstü tezler incelenerek genel bir çerçeve oluşturulması amaçlanmıştır. Araştırmanın örneklemini Yükseköğretim Kurulu (YÖK) Ulusal Tez Merkezi veri tabanından erişilebilen Türkiye genelindeki 74 ulusal lisansüstü tez oluşturmaktadır. Bu tezler, nitel araştırma yöntemlerinden tematik içerik analizi kullanılarak analiz edilmiştir. İncelenen ulusal lisansüstü tezler 13 tema altında analiz edilmiştir: “yıl”, “tez türü”, “eğitim alanı”, “araştırma tasarımı/yöntem modeli”, “deneysel araştırma türü”, “öğrenme yöntemi”, “örneklem türü”, “örneklem büyüklüğü”, “veri toplama yöntemleri/araçları”, “veri analiz tekniği”, “araştırmaya dâhil edilen bilimsel muhakeme becerileri”, “sonuçlar” ve “öneriler”. Bulgular, tezlerin çoğunun 2019 yılında yazıldığını ortaya koymuştur. Tez türlerinin çoğunluğu yüksek lisans tezi, eğitim alanlarının en sık matematik eğitimi olduğu görülmüştür. En sık araştırma tasarımı/yöntem modeli deneysel, en sık yarı deneysel tasarım ise deneysel araştırma türüdür. Ortaokul öğrencileri en sık kullanılan örneklem türüydü ve örneklem büyüklükleri çoğunlukla 0-25 arasındadır. Testler en sık kullanılan veri toplama yöntemleri/araçlarıydı ve geçerlilik en çok kullanılan veri analiz tekniğiydi. Argümantasyona dayalı öğrenme en çok tercih edilen öğrenme yöntemiydi. Araştırmada en sık ele alınan bilimsel muhakeme becerisi, özellikle matematiksel muhakeme becerilerine odaklanan matematiksel muhakemedir. Sonuçlar ve tartışmalar, öğrencilerin bilimsel muhakeme becerilerindeki gelişmeleri sıklıkla vurguladı. Önerilerde, araştırmacılara genellikle bilimsel muhakeme becerilerini geliştirmeyi amaçlayan uygulamalar geliştirmeleri tavsiye edilmektedir.
