Bu araştırma, 8.sınıf öğrencilerinin ölçmede tahmin performanslarının ve kullandıkları
stratejilerin incelenmesi üzerine yapılmış nitel bir çalışmadır. Araştırma Ordu ilinde
bulunan bir ortaokulda 2020-2021 eğitim-öğretim yılı içinde ölçüt örnekleme
yöntemiyle seçilmiş 9 öğrenci ile yapılmıştır. Bu araştırmada öğrencilerin seçilen
gerçek hayat nesneleri/yerleri ile ilgili uzunluk, alan ve hacim tahmin
performanslarının ve kullandıkları tahmin stratejilerinin belirlenmesi amaçlanmıştır.
Veriler ölçmede tahmin sürecinde yapılan görüşmeler ve gözlemler yoluyla toplanmış,
araştırmanın alt problemleri doğrultusunda analiz edilmiştir.
Araştırmanın sonucunda, öğrencilerin ölçmede uzunluk, alan ve hacim tahminlerinin
çoğunun gerçek değerin altında olduğu ve nesneler/yerler büyüdükçe tahminlerin
gerçek değerden uzaklaştığı belirlenmiştir. Bunun yanında akademik başarı arttıkça
öğrencilerin uzunluk ve hacim tahmin performanslarının arttığı, alan tahmin
performanslarının ise azaldığı anlaşılmıştır. Diğer taraftan öğrencilerin uzunluk
tahmin performanslarının, alan ve hacim tahmin performanslarından daha iyi olduğu
sonucuna ulaşılmıştır. Ayrıca nesnelerin/yerlerin boyutları büyüdükçe kullanılan
tahmin stratejilerinin sayısının arttığı ve doğru tahmin stratejisi seçen öğrencilerin
daha iyi tahmin yaptığı belirlenmiştir. Öte yandan öğrencilerin uzunluk tahminlerinde
en fazla karşılaştırma stratejisini kullandığı alan ve hacim tahminlerinin tümünde ise
formül kullanarak tahmin yaptıkları ortaya çıkmıştır. Ayrıca tüm nesneler/yerler
dikkate alındığında akademik başarısı yüksek olan öğrencilerin diğer öğrencilere göre
daha fazla strateji kullanarak tahmin yaptığı belirlenmiştir.,This research is a qualitative study of 8th grade students' estimation performance of
measurement and the strategies they use. The research was conducted with 9 students
selected by criterion sampling method in a secondary school in Ordu province in the
2020-2021 academic year. In this study, it was aimed to determine the length, area and
volume estimation performances of the students and the estimation strategies they used
regarding the selected real-life objects/places. The data were collected through
interviews and observations made during the estimation process and analyzed in line
with the sub-problems of the research.
As a result of the research, it was determined that most of the students' estimation of
length, area and volume in measurement were below the exact value and the
estimations deviated from the true value as the objects/places grew. In addition, it was
understood that as the academic success of the students increased, the length and
volume estimation performances became closer to the exact value while the area
estimation performances decreased. On the other hand, it was concluded that the length
estimation performances of the students were better than the area and volume
estimation performances. In addition, it was determined that as the size of the
objects/places increased, the number of prediction strategies used increased and the
students who chose the correct prediction strategy made better predictions. On the
other hand, it was come out that the students used the comparison strategy the most in
length estimations, and they made estimations using formulas in all of the area and
volume estimations. In addition, considering all objects/places, it was determined that
students with high academic success made predictions by using more strategies than
other students.
