The objective of the GeoGebra Step-by-Step Tutorial Series is not only to teach the readers how to use the software, but also to suggest how to use GeoGebra in teaching and learning mathematics. Most of the tutorials are (or will be) linked to related articles containing explanations and proofs about the mathematics discussed in the tutorials.
The tutorials guide you step-by-step through various iPhone and iPod touch apps for special needs. Many of the included apps are also available for the iPad; however, the screen designs may vary slightly across iOS devices.
Learn about the 1930s through eight exhibitions: The Depression, The New Deal, The Country, Industry, Labor, The City, Leisure, and American People. Artworks from the Smithsonian American Art Museum collection are supplemented with other primary source materials such as photographs, newsreels, and artists' memorabilia. Users can explore this virtual space and find information by clicking on people and objects. Visitors can gather artworks and place them in their bin for later documentary production. The theater's feature presentation is a series of interviews produced by the Smithsonian American Art Museum, Abstract Artists Describe the 1930s. Additionally, user-created documentaries can be viewed from the theater's balcony. Go to the theater's projection booth to find PrimaryAccess and a movie-making tutorial.
