Physics tutorials are worksheets that guide students to answer conceptual questions. Two well-known sets of physics tutorials, the Tutorials in Introductory Physics (TIP) and Open Source Tutorials (OST), are reported to emerge from distinct conceptual change principles. For example, TIP is often associated with "elicit-confront-resolve", while OST is connected with "refining intuitions." Based on the analysis of interviews with tutorial authors and of the tutorials themselves, we looked for similarities between the tutorials. We identified a pattern that is common to both sets of tutorials, which we call the "revisiting" strategy: students are asked to return to a problem they have already examined. Elicit-confrontresolve and refining intuitions can both be examples of revisiting, suggesting that revisiting is an important and general technique that illuminates the similarity between the two sets of tutorials.
