The result demonstrate that quartet card teaching aids are significantly effective in improving student learning outcomes; a t-tes anslysis at a significance level 0f 0,05 yielded a calculated t values =4,362 and a Sig. (2-tailed)=0,000. Meanwhile, the t-table value n-2 or 30-2=28, was determined to be 2.048. Since > ( 4,362 > 2,048) and the significant level was less than 0,05 (0,000< 0,05), the null hypothesis was rejected.]]>
