This teaching guide introduces students to early 20th century European and American art. Through critically viewing and discussing art images and participating in related activities, students are encouraged to explore the historical and cultural context within which the art was created. This guide includes background information and an overview essay about major art trends, including: Nonrepresentational Art; Fauvism; German Expressionism; Cubism; Futurism; Dada; Surrealism; and Social Realism. A description and artist's information regarding 20 slides is followed by discussion questions and lesson activities that explore general issues as well as: "Elements and Principles of Design"; "Expressive Use of Color and Form"; "Abstraction"; "Dreams and Fantasy"; "Art and the Machine Age"; and "Art and Social Issues." The lessons may be presented nonsequentially. Black and white reproductions of the slides are included in the text. Endnotes and a 5-item bibliography conclude the guide. (MM)
