The present research intends to by way of comparing traditional and active methods of teaching demonstrate which of the following methods: Team Effectiveness Design (TED), Team Member Teaching Design (TMTD), Performance Judging Design (PJD) & Clarifying Attitudes Design (CAD) is/are more effective in increasing reading literacy and comprehension of the pupils in the Tehran fourth grade elementary. The research population consisted of all girls and boy pupils in Tehran’s fourth grade elementary schools. The Sample consisted of 10 classes selected by cluster sampling method. A semi- experimental design with Pretest- posttest control group was used. Teachers received training in two sessions. Data were analyzed using the one way analysis of variance and two way analysis (2×5design) and Tukey's Honestly Significance Difference Test (HSD). The results show that differences between traditional and activity methods of teaching were not significant. Interaction effect between methods of teaching and gender was significant. In fact by controlling gender the difference between traditional and activity methods of teaching was not significant. Boy students who received traditional methods of teaching showed the best performance in boys groups; But in girls groups, those who were exposed to traditional methods exhibited the weakest performance. The highest amount of gender effect belongs to the Performance of Judging Design, thus girls in this group ranked exhibited the highest performance barely lower than their performanceon Team Effectiveness Design whereas in boys group the lowest performance pertains to this group, i.e. Performance Judging Design.
