Given the p-value of .50, which is significantly higher than the common alpha level of 0.05, there is not enough evidence to reject the null hypothesis. This suggests that any observed differences in exam scores among the classrooms are likely due to chance. Rejecting the research hypothesis is the appropriate step, as it implies accepting the null hypothesis that there are no significant differences between the groups.
