Online Beceri Değerlendirme Aracının Kullanılabilirliğinin Değerlendirilmesi

Öz

Bu çalışmada, düşük beceri seviyesine sahip yetişkinlerin okuryazarlık, sayısal ve dijital becerilerinin değerlendirilebilmesi için geliştirilen online beceri değerlendirme aracının kullanılabilirliğinin değerlendirilmesi amaçlanmıştır. Bu amaç doğrultusunda, çalışma grubunu, 18-40 yaşları arasında ve en fazla ortaokul mezunu olan 14 katılımcı oluşturmaktadır. Çalışmada, kullanıcı deneyimlerinin işe koşulduğu kullanıcı tabanlı yöntem kullanılmış ve online beceri değerlendirme aracının kullanılabilirliğinin değerlendirilmesinde, ISO 9241-11 tarafından belirlenen etkililik, verimlilik ve memnuniyet ölçütleri temel alınmıştır. Bu bağlamda, görevlerin tamamlanma oranı olarak kabul edilen etkililik ile görevlerin tamamlanma süresi olarak kabul edilen verimlilik ekran kayıtlarından elde edilen verilere göre belirlenmiştir. Memnuniyet ise araştırmacılar tarafından geliştirilen anketten elde edilen veriler doğrultusunda belirlenmiştir. Elde edilen bulgular, katılımcıların, görevlerin çoğunluğunu tamamlayabildiklerini ve sistemin kullanımı ile ilgili genel olarak memnun olduklarını göstermiştir. Bunun yanı sıra, kullanılabilirlik testi sırasında yapılan gözlemler ve ekran kayıtlarının detaylı incelenmesi sonucunda bazı kullanılabilirlik problemleri tespit edilmiştir. Bu problemler, sistemin son kullanıcılara açılmadan önce, daha kullanılabilir olması adına sistemin tasarımında yapılacak güncellemeler için yol gösterici olmuştur.

Usability Evaluation of the Online Skill Assessment Tool

Öz

This study was conducted to evaluate the usability of the online skill assessment tool which was developed to evaluate the literacy, numeracy, and digital skills of adults with low skill levels. The sample consisted of 14 participants who were between the ages of 18 and 40 and who had graduated from secondary school at most. In the study, the user-based method, in which user experiences are employed, was used, and according to the effectiveness, efficiency and satisfaction criteria determined by ISO 9241-11, the usability of the online skill assessment tool was evaluated. According to the data obtained from the screen recordings, effectiveness was considered as the completion rate of the tasks, and efficiency was considered as the completion duration of the tasks. Satisfaction was also considered as the values obtained from the questionnaire data. The findings indicated that the participants were able to complete most of the tasks and were generally satisfied with the use of the system. Some usability problems were identified as a result of the observations and the detailed examination of the screen recordings. These problems have been a guide for updates to render the system more usable before the system is used by end users.
