In Civic Education, you get an in-depth analysis of the 1988 NAEP test for Civics. The authors cover almost every possible scenario (student-teacher ratio as well as interest level in government) as they pick apart the test responses by high school seniors. The book discusses what students know, how they learn about governement and it also examines the instruction of civics courses. Most interestingly, the authors give their insights, based on the research, on how to improve or reform civics education in schools.
Although this book reads much like a text book, it still provides an adequate analysis of civics education in America.
