Investigation of the Development of the van Hiele Levels of Geometric Thinking in a Computer-Supported Collaborative Learning (CSCL) Environment
Öz: This study investigated the use of a well-designed computer-supported collaborative learning(CSCL) environment, namely Virtual Math Teams (VMT), to develop middle school students’ geometricthinking. It also looked into students’ VMT discourse to better understand factors leading to higher vanHiele levels of geometric thinking. The participants of the study were selected from middle schoolstudents who were at the visual geometric thinking level. For treatment, students were presented with aset of activities on quadrilaterals, which were developed based on van Hiele’s phases of learninggeometry, within the VMT environment. The data were collected using the van Hiele Geometry Test. TheVMT chat logs were qualitatively analyzed using the three-core collaborative problem-solvingcompetencies used in the Programme for International Student Assessment (PISA) 2015. The resultsshowed that the participants significantly developed their van Hiele Geometry Test scores after theintervention. Qualitative results pointed out that collaborative competencies could be essential indeveloping students’ geometric thinking levels within the VMT environment. Considering that ininternational assessments Turkish students score lower than the international average in geometry and thelowest in the collaborative problem-solving area, it becomes even more important to integrate CSCLenvironments into Turkish curricula
Anahtar Kelime: Bilgisayar Destekli İş Birliğiyle Öğrenme Ortamında vanHiele Geometrik Düşünme Seviyelerinin Gelişiminin İncelenmesi
Öz: Bu çalışmada bilgisayar destekli iş birliğiyle öğrenme aracı olarak geliştirilmiş olanSanal Matematik Takımları (VMT) ortamında ortaokul öğrencilerinin vanHiele geometrik düşünme düzeylerinin gelişimi incelenmiştir. Aynı zamanda, geometrik düşünme düzeylerinin gelişimine yol açan faktörleri daha iyi anlamak için öğrencilerin VMT söylemlerine nitel olarak bakılmıştır. Katılımcılar görsel vanHiele geometrik düşünme düzeyinde olan ortaokul öğrencileri arasından seçilmiştir. Uygulama olarak öğrencilere vanHiele’nin geometriyi öğrenme aşamaları dikkate alınarak dörtgenler konusunda geliştirilen aktiviteler VMT ortamında sunulmuştur. Öğrencilerin geometrik düşünce seviyelerindeki değişiklik vanHiele Geometri Testi kullanılarak değerlendirilmiştir. VMT sohbet kayıtları Uluslararası Öğrenci Değerlendirme Programı (PISA) 2015’te kullanılan üç temel işbirliği yeterliliği göz önüne alınarak nitel olarak analiz edilmiştir. Bulgular uygulama sonunda öğrencilerin vanHiele Geometri Testi skorlarını anlamlı bir şekilde arttırdıklarını göstermiştir. Nitel analiz sonuçları ise işbirliği yeterliliklerinin VMT ortamında öğrencilerin geometrik düşünme seviyelerini geliştirmede önemli bir faktör olabileceğine işaret etmektedir. Türk öğrencilerin uluslararası değerlendirmelerde geometride uluslararası ortalamaların altında ve iş birliğiyle problem çözme alanında sıralamada en sonda yer aldığı göz önüne alındığında, bilgisayar destekli işbirliğiyle öğrenme ortamlarının müfredata entegrasyonu daha da önem kazanmaktadır
