TED for the rest of us.\nThe main purpose of the project Videolectures.Net is to provide free and open access of a high quality video lectures presented by distinguished scholars and scientists at the most important and prominent events like conferences, summer schools, workshops and science promotional events from many fields of Science. The portal is aimed at promoting science, exchanging ideas and fostering knowledge sharing by providing high quality didactic contents not only to a scientific community but also to a general public. All lectures, accompanying documents, information and links are systematically selected and classified through the editorial process taking into account also users' comments.

K. Juuti, and J. Lavonen. NorDiNa, (2006)Construction of research based teaching sequences through Developmental research (Linsje, 1995), Educational reconstruction (Duit, Komorek & Wilbers, 1997), or Ingenierie Didactique (Artigue, 1994), can be considered very similar with design-based research. On the one hand, these approaches take into careful consideration students’ previous knowledge and emphasise basic scientific concepts and how they are related to the teaching sequence (Méhuet, 2004) and on another hand they aim to design the artefacts. For example, Andersson and Bach (2005) produced a teacher guide as an artefact describing the research-based sequence for teaching geometrical optics. However, these approaches focus on research-based design and the adoption of the innovations needs, for example, teachers’ in-service training.
