A common misconception about gangs is that they resemble past images of motorcycle riders. Society is now faced with what are called "hybrid" gangs whose members are usually 14 to 16 years of age, who dress conservatively, who display subtle gang identifiers, and who are motivated by a combination of profit and poor family life. This booklet contains information to help teachers identify gang members and gang activities on their campus. The first step to solving gang problems is to be aware that they do exist. Teachers are essential to gang intervention and prevention because of the amount of time children spend in the classroom each day. Some of these students can be saved from a life of crime if they are diverted from gang activities at an early age. Some of the topics covered in this booklet are definitions; types of gangs; gang awareness in the classroom; gang attire, tattoos, graffiti, and hand signals; and language. Further discussion is offered on why kids join gangs and the various types of gangs present in society, such as delinquent youth-gangs, traditional turf-based gangs, gain-oriented gangs, and violent/hate gangs. Finally, suggestions are given as to what schools can do to limit gang activities. (RJM)
