Students can make recordings of texts and annotated images such as charts, graphs, satellite photos and other scientific visualisations. The organising structure of the Collaboratory Notebook's database is built upon a library metaphor, with a bookshelf, notebooks, and pages being the primary interface elements. When a student, teacher or scientist logs on, his bookshelf displays all of the notebooks which he is permitted to read and write into. The CoVis Project is a good example of learning as an active, constructive process. Work in CoVis is highly interactive.
Students can construct knowledge by investigation.
Replication studies, in which students test the theories or hypotheses of researchers also fall into this category. Learning as a situated process In the CoVis project, the research sources display high of authenticity. Students investigate Internet and so they can access many different organisations for actual data. For example satellite pictures from the meteorological institute are really up to date. Students can find actual weather maps, so they can try a forecast for the next days.
