Molekül Modeli Uzamsal Yetenek Testi Geliştirme Çalışması

Öz

Kimya başarısı ile uzamsal yetenek arasında olumlu bir korelasyon vardır.  Bunun nedeni kimya alanının molekül, molekül geometrisi, izomerlik gibi uzamsal kavramlar içermesidir. Uzamsal yetenek kavramının eğitim alanındaki öneminden dolayı son asırda uzamsal yeteneğin tespit edilmesi ve geliştirilmesi adına birçok çalışma yürütülmektedir. Bu çalışmanın amacı molekül modellerinden faydalanılarak uzamsal yetenek testi geliştirmektir. Araştırmacılar tarafından hazırlanan ölçek 107 Fen Bilgisi Öğretmenliği öğrencisine uygulanmış ve 28 maddelik nihai hali elde edilmiştir. Ölçeğin ortalama madde güçlüğü 0,619 , ortalama ayırt edicilik indeksi 0,513 olarak hesaplanmıştır. Güvenirlik analizi sonucunda (KR-20: 0,87 ; Split-Half: 0,743 ) ölçeğin uygulama sonucunda güvenilir sonuç verdiği tespit edilmiştir.
