Uzamsal Yönelim Becerilerini İçeren Bir Gerçek Yaşam Probleminin Çözüm Sürecinden Yansımalar: Badana Problemi

Araştırmanın amacı, öğrencilerin gerçek yaşamdaki bir problemin çözüm sürecindeki uzamsal yönelim becerilerini de içeren modelleme yaklaşımlarını incelemektir. Daha önceden modelleme deneyimi olmayan katılımcılara bir gerçek yaşam problemi verilmiş ve çözümlerini posterler hazırlayarak sunmaları istenmiştir. Öğrencilerin çözümleri probleme özgü bir rubrik ile analiz edilmiş ve çözüm yaklaşımları gerçek model oluşturma, matematiksel model oluşturma, matematiksel olarak çalışma ve sonuçları gerçek yaşama göre yorumlamayı içeren modelleme basamaklarına göre değerlendirilmiştir. Çalışmanın bulguları öğrencilerin gerçek modellerinin kişisel deneyimlerinden ve uzamsal yönelim becerilerinden doğrudan etkilendiğini göstermiştir. Oluşturulan matematiksel modeller gerçek modellere dayalı olmuş ve öğrencilerin matematiksel modelleri oluştururken matematiksel bilgilerini ve farklı gösterimleri göz önünde bulundurdukları görülmüştür. Matematiksel olarak çalışırken, modelleri doğru bir şekilde çözmüşler ancak çoğunlukla birimleri ifade etmekte zorlanmışlardır. Modelleme deneyimi olmayan öğrencilerin matematiksel sonuçları gerçek yaşam bağlamında yorumlayabilmeleri dikkat çekici bir sonuç olmuştur. Bunun nedenleri, hepsi için anlamlı bir gerçek yaşam bağlamında çalışmış olmaları, okul dışında araştırma yapmış olmaları ve böylece gerçek verilere ulaşabilmeleri olarak belirlenmiştir.

Anahtar Kelimeler:
