The effectiveness of the werewolf game to develop students' ability in formulating language expressions for interaction in role-play activity

This study aimed to determine the effectiveness of the Werewolf Game in developing students’ ability to formulate expressions for interaction, such as asking opinions, giving opinions, asking permission, giving permissions, agreement, and disagreement, within role-play activities. This research employed a quantitative approach with a pre-experimental design with one-group pre-test and post-test, involving 31 students of class 8E at SMP Negeri 3 Peterongan PP Darul ‘Ulum Rejoso – Jombang. The results of the study indicated a significant improvement in students’ abilities after the treatment. Based on the statistical analysis using the Wilcoxon Signed Ranks Test, a significance value of 0.000 (p < 0.05) was obtained, meaning that the Null Hypothesis (H0) was rejected and the Alternative Hypothesis (Ha) was accepted. This was further supported by the average N-Gain score of 0.7239 (72.4%), which falls into the High category. Observations during the treatment also showed an increase in student engagement, rising from 80.7% to the 90.4% in the second session. In conclusion, the Werewolf Game is effective in developing students’ ability to formulate expressions for interaction in role-play activity.
