Background: This auto-ethnographic study describes research conducted in a science teacher education program at a state university in Turkey, where I had taught the 'laboratory applications' course for the four previous years. While the students learned the basic skills needed to implement a laboratory course, I detected some deficiencies in their understanding of scientific practices. Consequently, I decided to adopt a different approach. In the fall of 2013 to 2014, I participated in a project aimed at improving pre-service science teachers' understanding of scientific practices (SPs) using a model known as the Benzene Ring Heuristic (Erduran and Dagher 2014).Results: This project helped me to re-design my course, emphasizing the integration of SPs into lesson planning and teaching. As I taught the re-designed course, I gathered data from various sources, including pre-and post-interviews, audiotape recordings of lessons, students' lesson plans and reflections, and my own and my colleague's reflections after teaching.
