Over the last 50 years, the United States Supreme Court has made several rulings that have had lasting effects on the American public educational system. But no ruling has been more influential than the "Brown v. Board of Education Topeka, Kansas," decision the Court handed down in 1954. 2004 marked the fiftieth anniversary of this seminal case involving school desegregation. Not only did this decision end the legal doctrine and myth of "separate but equal" opportunity for black citizens, it also set a precedent for equal access to education for other groups including women and individuals with mental and physical disabilities. This article recommends some Internet sites that provide lesson plans that could be used in a fifth or sixth grade classroom to investigate the "Brown" decision and the influence it has had on American public education and society. By analyzing primary and secondary sources on one or more of these selected web sites, students can gain a greater understanding of the importance of the court's decision and its relevance today.
