The Visual Thinking Strategies Approach to Teaching Argument Writing: A Professional Development Model.

This pilot study evaluated a novel professional development (PD) model designed to prepare K–12 educators in high-need rural school districts to teach evidence-based argument writing. The PD model showed teachers how to engage students in discussions about visual art using Visual Thinking Strategies (VTS) to enhance students' argumentation writing. Twenty intervention teachers completed the PD program and conducted lessons in VTS and argument writing. Intervention teachers, compared with 34 comparison teachers, improved their perceived knowledge of critical thinking concepts, ability to teach critical thinking concepts, knowledge of concepts related to argument writing, and actual ability to perceive and analyze artistic work and understand characteristics used to convey intent and meaning (Hedges's g > 0.50). Students in the intervention condition (N = 210 in K–11) improved their argument writing skills. Given the quasi-experimental design and small sample size, these findings should be viewed with caution but suggest promise. [ABSTRACT FROM AUTHOR]
