Analysis employed paired and independent sample t-tests, Cohen's d, and N-Gain scores using SPSS. Results showed significant improvements in the experimental group: learning interest increased 68.2% vs 33.3% (control), motivation 67.2% vs 30.1%, and achievement 56.4% vs 29.5%. All differences were statistically significant (p < 0.001) with large effect sizes (Cohen's d > 1.8) and high N-Gain scores (71.60%-76.19%). The gamification learning model assisted by Wordwall media proved highly effective in enhancing students' learning interest, motivation, and achievement in Economics education.]]>
