The Impact of Prior Knowledge on the Usability Evaluation of a Competitive Game- Based Learning System Including Item Bank

Abstract

By using a competitive game-based learning system including item bank, this study aims to explore the impact of prior knowledge on Nielsen, J’s usability evaluation. The results show that it still needs improvement for “Aesthetic and minimalist design” and “Help and documentation”. Regarding to prior knowledge, the average scores for high prior knowledge learners are significantly higher than those for low prior knowledge learners on “Visibility of system status”, “Match between system and the real world”, “User control and freedom”, “Consistency”, “Error prevention”, “Recognition rather than recall”, “Flexibility and efficiency of use” and “Help users recognize, diagnose, and recover from errors”. It means that high prior knowledge learners are more satisfied than low prior knowledge ones.
