To investigate instructional planning strategies that impact student improvement in argumentative writing, the teacher-researcher implemented an Integrated Writing intervention in a seventh-grade urban school classroom to impact student writing, student feedback, and teacher reflection. Utilizing a mixed-methods Action Research study, the teacher-researcher collected qualitative and quantitative data during two 4-week instructional units utilizing a blogging site. Two iterations of data were analyzed for the inclusion of cognitive complexity. This study showed the effectiveness of using the Integrated Writing intervention in promoting students' ability to write effective cognitively complex arguments.
