For the past three and one-half years, the Science Education Department at the University of Copenhagen has worked with IPN and eight other European partners to investigate formative and summative assessment methods to support and improve inquiry-based approaches in European science, technology and mathematics (STM) education. Now that the project is ending, we have some preliminary results about the four feedback methods tested in secondary classrooms. This seminar will share some of these early results and provide an opportunity for IPN to use their analytical skills to give us a perspective on them.
