The science education community agrees that pedagogical practices based on IBSE methods are more effective. But the reality on the ground is different. For various reasons, this type of teaching is not practiced in most European classrooms. INSPIRE counteract this by developing and offering a one-year practically based IBSE teacher training course that will reach out to hundreds of teachers, and in turn thousands of children, in 11 European countries. The course is run through 14 Botanic Gardens and Natural History Museums - some of Europe’s most inspirational cultural and learning institutions. These places act as catalysts, training and supporting teachers and educators to develop their proficiency in IBSE and become reflective practitioners. Most of the partner institutions have experience in delivering IBSE. To ensure excellence, theoretical rigour and project progression, two highly regarded science education research institutions participate: King´s College UK (informal learning; practitioner’s research) and University of Bremen BRD (research into teacher education). The training locations, the practical nature of the course, the support offered and the subject content encourages teachers and educators to enrol in INSPIRE courses and try out IBSE in their everyday teaching. Biodiversity loss and climate change are the major global issues of the 21st century and many teachers are looking for innovative ways to tackle these subjects. INSPIRE training supports teachers to do just that and introduce them to institutions where children can carry out ‘real’ investigations and see science in action. INSPIRE training courses are promoted through national systems that support professional development for teachers as well as informal education training networks. The website encourages the uptake of IBSE. It promotes dialogue between partners and teachers, showcase best practice published on other EU websites and highlight the results of practitioner research in IBSE.
