‘SALiS– Student Active Learning in Science’ intends to overcome a centralized and teacher-centered paradigm in science education as it is still predominant in different countries of central and eastern Europe. National reforms, e.g. in Georgia, ask for more student-active and problem-based science education under inclusion of students’ hands-on and inquiry-based learning in the lab. Unfortunately, curricula, teaching materials and teacher training facilities are not well enough developed to support sufficiently the intentions of the reform in many countries. Within an international network and funded by the TEMPUS-programme, ten partners from six countries seek to innovate respective teacher training practices, in their content and infrastructure."
