This book includes an edited collection of papers containing illustrations of teaching approaches and of students' learning acquisitions in the science teaching laboratory, presentation of new evaluation tools, theoretical frames and positions concerning laboratory work. The aim of the book is both to improve the design and organisation of innovative laboratory practices and to provide tools and exemplary results for the evaluation of their effectiveness, adequate for labwork in order to promote students' scientific understanding in a variety of countries. The book focuses the discussion on the role of labwork in upper secondary and in higher education. The papers are based on research and developmental work carried out in five European countries in the context of the European Project "Labwork in Science Education" (LSE), which was funded by the European Union, and provide a unique framework for gaining deeper insights into the role of experimentation in science teaching and learning in a variety of contexts. This substantial and significant body of research is now made available in English.
