The curriculum guide is designed to help high school art teachers develop a course of instruction to enhance student understanding and knowledge of 20th century art and architecture. A major objective of the course is to develop student ability to recognize, compare, and analyze style, form, and expressive content as a means of achieving greater insight into the meanings of 20th century art and architecture. The suggested course is divided into three parts: chronological overview; comparative analysis of movements, styles, and techniques; and independent student research. Three major sections of the guide present sample teaching units based on concepts in each of the three course areas. Each unit identifies its basic concept, a learning objective, instructional suggestions, assessment measures, bibliographic resources, and an activity to correlate the unit with the overall program of instruction. The guide can serve as the basis for a mini-course, a one-semester course, or a year's course. It can also be used in developing instructional objectives pertaining to art history which are included in most studio art courses. A briefly annotated bibliography cites 90 teacher and student resources. Appendices present a sample chronological overview of 20th century art and architects in chart form; and short descriptions of specific movements and styles in 20th century art and architecture.
