The purpose of this research was to know the influence of using picture card media toward students rational thinking skill. The research design was pretest-postest non equivalent group. Samples were X₅  and X₆ that was choosen by cluster random  sampling method. The data of research were  quantitative and qualitative. The quantitative data was taken from the average of  pretest and posttest scores which statistically analyzed with t-test using SPSS 17.0  in 95% confidence levels. The qualitative data which was analyzed descriptively were students learning activities and students responses about applicating picture card media through cooperative learning model type Group Investigation. The result of the  research showed that there was no significant effect of picture card media toward students rational thinking skill (t_{counting  (1,412)} < t_{table (1,671)}). Most of student learning activities categorized as high average (76,57 %). Furthermore the students gave positive responses to this research.
