The Learning study was introduced in Hong Kong and Sweden some fifteen years ago. It combines the teacher driven Lesson study with the theoretical grounded Design experiment. In the Learning study, the educator (acting as a facilitator) and the teachers have a shared goal; to gain knowledge about the nature of the object of learning in order to enhance students’ learning. In an iterative process of planning and evaluating lessons the teacher team collects data that is used for inquiring how teaching affect students’ learning. In this process a theory of learning, commonly variation theory (Marton, Runesson & Tsui, 2004; Marton, 2014,) is used as a guiding principle. Several studies have demonstrated that the Learning study has effect, not just on students’ learning, but on teachers’ professional development too. However, the educator can benefit from the Learning study also. In the presentation Runesson demonstrated how and what educators can learn from participating in the Learning study.
