Prospective student web pages of universities are an important source of communication in providing information to their stakeholders in social and academic terms, therefore, these pages are expected to be easy to use, secure and in accordance with accessibility standards. This article presents the accessibility, usability, and security evaluation of prospective student web pages of universities in Turkey. For this purpose, 147 web pages for prospective students of universities were determined and evaluated with various automated testing tools. In addition, after the evaluation, clustering analysis was carried out to determine similar behavior patterns of universities. The results showed that the majority of state and private universities paid less attention to accessibility and quality of use. Evaluated web pages were found to have a low compatibility level according to the WCAG 2.0 directive. No critical security issues were identified, but there were certain areas that needed improvement. Additionally, this study offers some valuable suggestions to web developers and administrators for resolving accessibility, usability, and security violations of web pages.

Türk Üniversitelerinin Aday Öğrenci Web Sayfalarının Erişilebilirlik, Kullanılabilirlik ve Güvenlik Açısından Değerlendirilmesi

Üniversitelerin aday öğrenci web sayfaları sosyal ve akademik anlamda paydaşlarına bilgi sağlama konusunda önemli bir iletişim kaynağıdır, bu sebeple bu sayfaların kullanımının kolay, güvenli ve erişilebilirlik standartlarına uygun olması beklenir. Bu makale, Türkiye’deki üniversitelerin aday öğrenci web sayfalarının erişilebilirlik, kullanılabilirlik ve güvenlik değerlendirmesini sunmaktadır. Bu amaçla, üniversitelerin aday öğrencilerine yönelik 147 adet web sayfası tespit edilmiş ve çeşitli otomatik test araçları ile değerlendirilmiştir. Ayrıca, değerlendirme sonrası üniversitelerin benzer davranış kalıplarının belirlenmesi amacıyla kümeleme analizi yapılmıştır. Sonuçlar, devlet ya da vakıf fark etmeksizin üniversitelerin büyük çoğunluğunun erişilebilirlik ve kullanım kalitesine daha az dikkat ettiğini göstermiştir. Değerlendirilen web sayfalarının WCAG 2.0 yönergesine göre düşük uyumluluk seviyesine sahip olduğu görüldü. Güvenlik açısından kritik bir sorun tespit edilmemiştir ancak geliştirilmesi gereken belirli noktalar bulunmuştur. Ayrıca bu çalışma, web sayfalarının erişilebilirlik, kullanılabilirlik ve güvenlik ihlallerin çözülebilmesi için geliştiricilere ve yöneticilere bazı değerli öneriler sunmaktadır.
