Abstract:
A common problem in vocabulary learning is the decline in student enthusiasm due
to teaching methods that are less interactive and not engaging enough, which often
leads to suboptimal learning outcomes. This research aims to address this issue by
exploring the effectiveness of the Knoword game as an innovative game-based
learning platform that elevate vocabulary mastery. The study was conducted at
SMA Swasta Al Maksum, focusing on elevating students' vocabulary mastery in
English subjects. The quantitative design with pre-test, treatment, and post-test was
employed, involving an experimental class and a control class. The results showed
that the Knoword Game significantly elevate students' vocabulary learning
outcomes. In the experimental class, the average pre-test score of 56 increased to
80.75 after the treatment. Meanwhile, in the control class, which used traditional
methods, the average score increased only from 49.25 to 57.00. The t-test analysis
revealed a t-count of 10.528 and a t-table value of 1.729, indicating that the
Knoword Game method was more effectiveness than traditional teaching methods,
as Ha was accepted and Ho was rejected. The findings highlight the potential of
game to enhance student engagement and improve learning outcomes in vocabulary
mastery
