Classroom behavioral interventions can be thought of as a subset of the field of behavior modification, so you'll really need to get some background in the field in order to be able to understand the terminology and the way it is used. I'll try to explain terms as I go, followed by some recommendations for references. (Sorry for writing so much--believe it or not this is the edited version!)
Put as simply as possible, think of it classroom behavioral interventions an ongoing multi-stage process: observation, analysis, designing the intervention, implementing the intervention, assessing the results, re-designing/refining the intervention, re-implementation, etc until the intervention is successful. then you get to start the process all over again to see 1) if a maintenance program is needed, and 2) if so, what that program should be. Throughout the process, record keeping is vital--you have to know what is going on, what has been done, etc.
"Observation" consists of observing the student in a variety of contexts, until you have a pretty good idea of what the problematic behavior(s) consists of. Then you develop a working definition of the behavior.
"Analysis" is the stage where you begin looking at the "ABCs": Antecedent (what precedes or triggers the behavior, in what environment or circumstances it takes place, etc--what causes the behavior), Behavior (of what does the behavior actually consist? try to break it down into stages you can define as discrete actions), and Consequences (what is the result of the behavior--what does the behavior do for the student exhibiting the behavior).
"Designing the intervention" can be thought of as the stage where you figure out what you are going to do to try to address the problem. Work from broad, general ideas to the specific, don't try to design the final intervention in one try. Be certain you can define every aspect of your intervention: the target behavior, your goals, and all stages of your intervention.
"Implementing the intervention" is the stage when you actually try out your intervention, under the circumstances for which it was designed. This can be a rather painful stage, the intervention probably won't be immediately effective so be sure to plan on adequate time for testing of the intervention.
" Assessing the results," "re-designing/refining the intervention," and "re-implementation" is the stage where many classroom interventions fail. These are the stages where you look at the results of your initial intervention, find ways to make it better, and test the new intervention. Many people ignore these stages, and either give up on the process after one try, or settle for mediocre results. (For the person designing and implementing the program, I'd suggest keeping these stages in mind. It is often frustrating when an intervention doesn't immediately work, and I find it very helpful for my own peace of mind to remember that, particularly during the initial stages, interventions often don't work as well as we would like. This isn't "failure," it is part of the process.)
When you finally have a successful program, you will need to decide if you need to continue the program on some level, or if the goal has been accomplished and you can gradually eliminate the program.
At all stages, problems can occur. Doesn't this sound like wonderful fun? Actually--most of the time--it is not as bad as it sounds. (But remember that qualifier!)
References may be tricky, in that I don't know how much psych background you have. I'll start at a very simple level and work up in complexity/specificity.
First, I would recommend getting a copy of Behavior Modification: What it is and how to do it by Garry Martin and Joseph Pear. There have been multiple editions of this book; for purposes of learning the basics of behavioral intervention almost any edition after the first is fine. The target audience of the book is college students with little-to-no background in the field of behavior modification, and minimal psychology background.
Secondly, you might consider Principles of Everyday Behavior Analysis by L. Keith Miller. This is another college textbook, and again, any edition after the first is suitable for classroom purposes. The book does assume more background than Martin & Pear, but it goes into more detail in analyzing and understanding behavior. The two books are complimentary, but probably best worked through in sequence rather than side-by-side.
If you shop used bookstores and online, and keeping in mind that almost any edition is acceptable, you should be able to find these two for about 5-10 USD each (plus shipping of course).
My third recommendation is more generic. A couple years ago I took a research methods class dealing with "action research." Much of the philosophical approach to action research is very similar to that of classroom behavior analysis/modification. You might find it useful to consider some of the literature on this. A lot of this can be found online.
When it comes to dealing with more extreme behaviors, particularly in a classroom context, I've found the work of V. Mark Durand to be very useful. His book Severe Problem Behaviors: A functional communication training approach can be very valuable in that it provides an example of a systematic approach that may be directly applicable, or may help you understand the process. In order to really benefit from the book though, you will need the background provided by the first two I recommended, or something similar.
Finally (for now at least), on a personal note: I was a SpEd student as a child, and can recall a number of what I now recognize as attempts at behavioral interventions. Many of these included elements that I found extremely aversive, even though I now understand that many of them were not intended that way. (Some were, but that was long ago when such things were accepted.) I would suggest that when designing and implementing interventions, you keep in mind that what you might find to be rewarding or non-aversive, your student may find to be punishing, or aversive. Try to see these things from the perspective of your student; it usually leads to better results.
