I believe the action research paradigm that knowledge is gained through action is accurate. I believe this can easily be demonstrated by putting a group of children on a bus and sending the to Washington DC. By interacting and seeing the museum, White House, and other buildings the children will easily learn far more about the government and how it works, then they ever would in the classroom. These same implications are true for everyone, not just the younger crowd.
In action research paradigm it is true that knowledge is gained through action accurate. On thing to do is the research first and then compare it to the knowledge that you have gained from this research. Once you do that you should be able to tell if the knowledge that is gained is accurate.
The action research paradigm that knowledge is gained through action is accurate. The action research paradigm is an interactive method of gaining knowledge through participation in experiments rather than just simple observation of human behavior. Action research is accurate because it provides first hand knowledge of a problem and it's solutions.
Knowledge is gained through reaction, not necessarily action. Since there can be no reaction without action, action is necessary for knowledge. Unfortunately for the action research model, the only way to really know the outcome of the research is if the experiment fails. Even then, the true nature of the failure may not be known. There are often too many variables to account for that cannot be controlled in action research.
