An Uneasy Guest in the Schoolhouse recounts how art education has been conceptualized, taught, and advocated for in the United States in the face of its persistent marginalization in the education system. Tracing various rationales offered from the 19th century onward, Winner argues that art education has failed to be justified as a good in and of itself--and this failure has affected both the status of visual art education in our schools and the quality of its teaching. Winner's comprehensive book maps recurrent pendulum swings between "traditional" and "progressive" approaches to art education in the United States, supplemented by her firsthand experiences observing art teaching in schools in China and Italy. Despite this problematic and uncertain past, 21st century art education in the United States and abroad has exploded with a wealth of new ideas aligned with the progressivism of the early 20th century and informed by the practices of contemporary art. As Winner details, an understanding of the history of art education, along with a focus on current challenges and opportunities, is essential for arts researchers, educators, and advocates, as well as anyone in the general public who cares about quality education in the 21st century.
