| Abstrak/Abstract |
In today’s globalized world, proficiency in foreign
languages, such as Korean, is of paramount importance. While
pronunciation is a fundamental aspect of language acquisition,
conventional assessment techniques are constrained by limi-
tations such as the subjectivity of human judgment, learn-
ers’ discomfort during live examination, and teachers’ limited
time to assess. This research presents the development of an
educational game based on virtual reality (VR) designed to
assess basic Korean pronunciation, with the aim of overcoming
the aforementioned problems. This study also evaluates the
effectiveness of the developed application, assessing several
key measures: usability, user experience and comfort, and the
alignment of the developed system assessment results with
human judgment. The methodology used in this research is
agile method for development, black box testing, evaluation of
usability and user experience, and correlation test between the
system assessment and the manual human assessment. The app
showed good usability with an SUS score of 72.625 and positive
UEQ scores for attractiveness (2.225), perspicuity (1.838), stim-
ulation (2.313), and novelty (1.863). A Spearman correlation
coefficient of 0.631 indicated significant agreement between
system and human assessments. The study demonstrates that
the VR-based educational game effectively facilitates impartial
Korean pronunciation assessment, enhances user experience,
and reduces manual assessment time for teachers by automating
the process. |
