The present study was used to teach
undergraduate students the concepts of computational simulation and measurement
uncertainty via discovery based learning. The study included
experimental-theoretical-numerical examination of heat conduction along a cylindrical
rod. Because it is a well-known fact that dealing with systems having complex
theoretical background distracts students’ attention, an easy to be
comprehended experimental system had intentionally chosen to allow the students
mainly focus on the computational simulations and measurement uncertainty.
Students were requested to compare the results obtained at each step and to
figure out the possible causes of discrepancies among the results if there was
any. The steps were repeated several times until the students satisfied with
the results.

Isı Transferinde Bilgisayar Destekli Simülasyon ve Ölçüm Belirsizliği Mefhumlarının Keşif Tabanlı Örnek Vaka Aracılığı ile Öğretilmesi

Öz

Bu makalede lisans
öğrencilerine bilgisayar destekli simülasyon ve ölçüm belirsizliği kavramlarını
proje tabanlı öğrenme usulü ile öğretebilmek için kullanılan bir çalışma
anlatılmıştır. Çalışma silindirik bir çubuk üzerindeki iletimsel ısı
transferinin deneysel, teorik, numerik incelenmesini içermektedir. Öğrencilerin
karmaşık teorik altyapıya sahip sistemlerle ilgilenmelerinin dikkatlerini
dağıtacağı iyi bilinen bir gerçek olduğu için teorik altyapısı rahatlıkla
anlaşılabilecek deneysel bir sistem kasıtlı olarak seçilmiştir ki bu sayede
öğrencilerin dikkatlerinin bilgisayar destekli simülasyonlar ve ölçüm
belirsizliği konuları üzerine yoğunlaşmaları hedeflenmiştir. Öğrencilerden her
bir adımda elde ettikleri sonuçları bir diğeri ile karşılaştırmaları istenmiş
ve varsa birbirleri arasındaki sapmaların muhtemel sebeplerini ortaya çıkarmaları
beklenmiştir. Her bir adımın öğrenciler sonuçlardan tatmin oluncaya kadar
tekrarlanması sağlanmıştır.
