Research-practice partnerships through lesson study: learning through the three worlds of experiences

Research practice partnerships through lesson study promises to deliver educational improvements in an era of evidence-based school and curriculum reforms. But learning from these experiences is not trivial but rather challenging in a complex ecology of classroom and school environments. So, how do researchers and practitioners learn from their experiences during their engagement in an RPP through lesson study? In this commentary, I introduce the idea of noticing possibilities from the three worlds of experiences - self, others, theories and observations - as the key to learn from these partnerships, as evidenced in the papers in this special issue.
