It's important to have a balance between the research and application of methods. Still, teachers can and should use research to help create their curriculums, and craft new activities to help students recall information. Once we understand more of the ins and outs of how people retain what they learn, developers can use these techniques to design technology that enhance students' education. After all, the research is only as useful as the people who apply it to their world.
There is no one size fits all solution, and we have created a variety off approaches to make our different learning systems work together.
