The Recommendations of the European Parliament on key competencies for lifelong learning released in 2006 summarise a noticeable tendency in the policies of the educational authorities across Europe many of which had redefined their educational aims in terms of competencies, increasingly focusing the curricula on the successful application of knowledge and skills rather than on simple transmission of knowledge. This tendency places increased demands towards teachers who are entitled to develop in their students’ practical skills for life and to assist young people to reach their full potential.Initiated in the European year of creativity and Innovation the KeyTTT project aims to support teachers in this challenge by producing an integrated solution that consists of teaching Methodology, Teachers’ Guidelines Book and Qualification Teacher Course addressed to teachers in mathematics and natural sciences who work in the course of the lower secondary education. The aim of the project is to equip teachers with tools that will help them to organise educational process oriented at learning as problem-solving or research-in-action activities that support and develop students’ creativity and key competencies such as basic competencies in science, maths and technology, digital competence, learning to learn, sense of initiative and entrepreneurship.The project intends to build up on up good practices created in school and out of school environment, incl. in projects’ settings. It will launch a multilingual web-site with educational recourses and innovative teaching materials.
