A randomized controlled trial was conducted to study the effectiveness of two readers' theater (RT) programs in promoting reading skills and motivation of dysfluent readers in Grades 3-4. One program (RT Goal) included a goal of preparing a performance for an audience (n = 50), while another program (RT Practice) did not include such a goal (n = 49). A group of dysfluent readers receiving traditional oral reading intervention (Control group; n = 59) and a group of classroom peers (Mainstream group; n = 159) served as controls. The results indicate that both RT groups and the Control group developed at a higher rate in oral reading speed during the intervention period than the Mainstream group. The RT Goal program was associated with higher engagement ratings and a temporary reduction in reading errors and oral reading anxiety. RT had no effects on silent reading skills or reading self-efficacy.
