Bu çalışmanın amacını sözcük geliştirme aktiviteleri sonucunda, iki grup öğrenci arasında sözcük sayı düzeyleri bakımından bir farklılığın olup olmadığının belirlenmesi oluşturmaktadır. Kontrol grubunda yer alan öğrenciler ek bir kelime çalışmasının yapılmadığı İngilizcede en sık kullanılan ikinci bin sözcüğü içeren normal müfredatı takip ederken, deney grubundaki öğrenciler ise İngilizcede en sık kullanılan ikinci bin sözcüğü içeren sözcük geliştirme aktivitelerinin normal müfredata entegre edildiği on dört haftalık programı izlemişlerdir. Bu araştırmanın çalışma grubunu, Yalova ilinde bir meslek yüksekokulunda 2010–2011 eğitim-öğretim yılında ikinci sınıfta öğrenim gören 88 erkek öğrenci oluşturmuştur. Bu çalışmada, Schmitt (2000) tarafından geliştirilen Sözcük Seviye Belirleme Testinin birinci versiyonu veri toplama aracı olarak kullanılmıştır. Uygulamanın ardından, deney grubu ile kontrol grubu arasında, sözcük sayı düzeyleri açısından deney grubu lehine anlamlı bir fark oluşmuştur
