Öz

Elektron optiği iyi bir matematiksel altyapı gerektirdiği için fen eğitiminde, özellikle fizik
eğitiminde anlaşılması zor bir konudur. Elektron optiğinde kullanılan kurallar, ışık optiğinden
alınmaktadır. Ayrıca, ışık optiğinde kullanılan formalizasyon son derece gelişmiş olduğu için, elektron
optiği tartışmalarında aynı terminoloji ve formüllerden yararlanılması bir gelenek haline gelmiştir. Bu
sebeple, ışık ve elektron optiği ile arasında analojiler kurarak ve simülasyon araçları kullanarak lisans ve
lisansüstü öğrencilerine elektron optiğinin temelleri basitleştirilerek öğretilebilir.
Çalışmamızda ilk olarak elektron optiğinin öğretiminde ilgiyi ve verimliliği sağlaması amacıyla
ışık ve elektron optiği arasında zenginleştirilmiş analoji inşa edilmiştir. Bu eşleşmede benzer kısımların
yanı sıra ortak olmayan ayrıştıkları noktalar da belirtilerek analoji zenginleştirilmiştir. Ek olarak, elektron
optiğinin öğretiminde bilgisayar simülasyon uygulamalarının (ray-tracing yöntemi) kullanımı ve bunların
anlamaya destekleri tartışılmıştır.

Anahtar Kelimeler

Analoji, ışık optiği, elektron optiği, yüklü parçacık optiği, odaklama, fen eğitimi.
