This paper presents early work on the "Jots" system, integrated with the Scratch programming environment, which aims to help learners reflect on their learning processes. The design of the software tool and associated pedagogical strategies is presented in the context of a map of reference frames, which are levels of analysis that learners move between as they reflect. The design of a study to evaluate and further develop the system is described.
