Histories of Blacks, Czechs, Germans, Jews, Mexicans, and Poles are provided in this resource guide. The histories are intended as a major background resource to help instructional staff members of the 45 school systems in Education Service Center, Region II, Corpus Christi, Texas, integrate ethnic heritage studies materials into classroom instruction. The history of each group begins with a brief description of contributions, customs, and facts. A detailed narrative, which often quotes primary source materials, follows. The section on Black history contains a list of important dates. The sections on Blacks, Czechs, and Jews, in addition to describing the general histories of these groups, also discuss their histories and experiences in Texas. Also included in the guide are a calendar of ethnic holidays and a bibliography of additional resource materials. (RM)
