Learncycle is a project of the National Diffusion Network which has trained hundreds of teachers and other school staff nationwide in a wide array of skills to improve the mainstreaming process and the education of the high-risk student. The project uses the "Learncycle Behavior Analysis Mainstreaming Model," which works to achieve a fit between the student and the mainstream environment by eliminating discrepancies between where the student is in terms of skill levels and response to instruction, and where the environment is in terms of what it expects and can provide. This manual works through an actual case as it presents the skills needed to implement the Learncycle five-step problem-solving method. The five-step method involves pinpointing and defining the problem behaviorally; observing and using principles of behavior analysis to understand the problem; intervention, via changing the consequences, reinforcing, creating a token economy, enlisting class support, changing teacher behavior, or making other changes; evaluation; and recycling. The manual also includes sections for special education consulting staff on ways to use the method to improve students' preparation in special classes and to optimize the environment for the receiving regular class teacher.
