This curriculum unit consists of four lessons that are designed to broaden students' understanding of art and culture; each lesson can stand alone or be used in conjunction with the others. The introduction offers a conceptual framework of the Artworlds unit, which takes an inquiry-based approach. The unit's first lesson, "Worlds within Worlds," is an interdisciplinary art and social science lesson, an introduction to the concept of culture--an understanding of culture is necessary before students can understand artworlds, the key concept of this curriculum resource. The unit's second lesson, "Places in the LA Artworld," the key lesson in this unit, introduces and illustrates the defining characteristics of an artworld. The lesson has students make an artworld bulletin board. The unit's third lesson, "Cruising the LA Artworld," asks students to apply their understanding of the defining characteristics of artworlds from the "Places in the LA Artworld" lesson to their analysis of art-related Web sites on LA Culture Net and beyond. The unit's fourth lesson, "Using and Understanding Art from Other Artworlds," helps students seek ideas for their own art making by looking at artworks from other cultures. This lesson helps students understand that objects called "art" in Euro-American cultures may have very different meanings and functions in the artworlds of other cultures. (BT)
