Considering the relevance of teachers' diagnostic competence for
understanding students' thinking and providing effective learning
opportunities, Macarena Larrain investigates the development of future
primary school teachers' diagnostic competence in error situations
already during initial teacher education. Using video vignettes of
classroom situations and samples of students' work, the author focuses
on fostering future teachers' competence to identify students' errors,
elaborate hypotheses about the causes of those errors and to design
appropriate strategies for supporting students in overcoming their
misconceptions. She also describes aspects of teachers' knowledge,
beliefs and experience that are relevant for the competence and its
development.
