Experimental Study 6+1 Traits Cover

This report presents the results of a study that examined the efficacy of professional development for teachers using the 6+1 Trait Writing model with respect to improving student writing skills. To achieve this purpose, a randomized experimental study was conducted in 2003-2004 in grades 4 to 6 to determine the extent to which a two-day workshop on the 6+1 Trait Writing model affected teacher practices and student achievement in writing. The study examined fidelity of implementation through a teacher survey on classroom practices to determine the extent to which teachers implemented the desired strategies and to describe differences between classroom practices of teachers in the treatment group and those of teachers in the control group. Student achievement in writing was measured by having students write on assigned prompts to produce narrative, descriptive, or persuasive pieces of writing.
