Bu çalışmanın amacı uzamsal görselleştirme problemleri çözme etkinliklerinin öğretmen
adaylarının zihinsel döndürme problemleri çözmelerine nasıl yardımcı olduğunu araştırmaktır. Bu amaçla
bir durum çalışması yapılmıştır ve çalışmada incelenen durum Ankara’da bir devlet üniversitesinde
eğitim gören matematik öğretmen adaylarıdır. Veri toplama araçları olarak Uzamsal Yetenek Testi (SAT)
ve görev temelli görüşmeler kullanılmıştır. Çalışmanın bulguları göstermiştir ki katılımcılar zihinsel
döndürme problemleri çözerken farklı yollar kullanmışlardır; verilen şekli zihinde döndürme veya verilen
şeklin parçalarının konumlarını veya desenlerini karşılaştırma. Buna ek olarak, uzamsal görselleştirme
problemleri çözmek katılımcıların çözüm yollarını keşfetmelerini, değiştirmelerini veya pratik yapmalarını
sağlayarak zihinsel döndürme problemlerini doğru ve pratik bir biçimde çözerken karşılaştıkları zorlukları
aşmalarına yardımcı olmuştur.

Anahtar Kelimeler

Uzamsal yetenek, uzamsal görselleştirme, zihinsel döndürme problemleri, matematik öğretmen adayları, görev temelli görüşmeler

A Case Study on the Ways How Engagement with Spatial Visualization Problem Solving Activities Helps Pre-Service Mathematics Teachers in Solving Mental Rotation Problems

Öz

The purpose of the present study is to investigate in what ways engagement with
spatial visualization problem solving activities helps pre-service mathematics teachers in solving mental
rotation problems. To achieve this purpose, a case study is conducted and the case of the study is the
group of five pre-service mathematics teachers studying in a public university in Ankara. Spatial Ability
Test (SAT) and task-based interviews are used as data collecting instruments. The results of the study
show that participants use different ways in solving mental rotation problems; mentally rotating the
figure or comparing the relative positions or patterns of the parts of the given figure. Additionally,
solving spatial problems help participants in exploring, practicing or shifting their ways of solving
problems to cope with the difficulties in solving spatial visualization problems requiring mental rotation
accurately and practically.
