Compare the public school approaches in your community or local district with those of public school models presented in your textbook readings, commenting on any similarities and/or dissimilarities of note.
I can tell you what our school, district, and state do about gang issues, but I don't think that will help you answer your question. These are all questions you can find if you ask the right people. First, the internet will be a great resource. Many states publish their policies and procedures for gangs online. Since you're in college, have you considered going back to your high school and asking your principal or SRO (or even former teachers? If they remember you, they can be a great source of information. Also, check your library's resources. Searching ERIC or other research banks can give you helpful information about polices and effective models for working with gang activity.
I would agree that websites which denote current statistics would be your best bet. Unfortunately, not all areas have the same problems and results will be vastly different when looking at the differences between rural and urban areas.
Your city and state governments would have statistics relevant to this inquiry: similarities and dissimilarities to the models. Part of your research--which is required to answer this--could include tracking these statistics down either through the reference department of your public library (Reference Librarians are our best friends!) or by calling and speaking with agencies, such as your local police department, that might be able to provide you with statistics.
I think a number of different initiatives in recent years concern promoting student choice and involvement in school, so that they feel they have a say and therefore have ownership in the school to which they go and have the ability to influence the decision making process and make their voice heard. This is such a vital part of challenging any discontent within society, as often illegal activity comes as a result of frustration at not being able to express your voice in any meaningful way.
The best resource for your research, in my opinion, is going to be high school SRO's or School Resource Officers, otherwise known as security and law enforcement officers on campus. Whenever a high school staff has a meeting about gang information, activity, and school policies and procedures, it is typically conducted by or with the direct influence of the SRO for the school as passed down from the district.
If I were you, I'd make a simple outline of the ideas presented in the book. Then, I'd interview several SRO's in your area (middle schools often have them as well, depending on the city in which you live), and see how the district policies match up.
It would be helpful to get the most accurate information possible. You might begin by talking with school principals, since they would presumably be in the position to give you a comprehensive overview of what is going on in their particular schools. They might be able to put you in touch with other knowledgeable persons. You might also wish to try to contact the school superintendent, whose office might also be able to give your valuable leads.
The school district in my area has been establishing more school choices for students during the past few years. Currently the emphasis is on academic programs like schools for math, science, and technology. We also have early college programs on university and technical college campuses. Some are geared toward gifted and talented students and others are for at-risk students. These programs, I believe, are similar to the concept of charter schools.
What are some of the models in your text? Also, what is the title of the textbook you are using? I may be able to provide more relevant details with that information.
I'm using " The Modern Gang Reader" third Edition.
