摘要：I had hoped to find research to support or to conclusively oppose my belief that quality integrated education is the most promising approach. For every study that contains a recommendation, there is another, equally well documented study, challenging the conclusions of the first...No one seems to agree with anyone else's approach. But more distressing: no one seems to know what works." Senator Fritz Mondale's quote illustrates a common plight. Educational research often produces contradictory results. Differences among studies in treatments, settings, measurement instruments, and research methods make research findings difficult to compare. Even frequent replications can prove inconclusive. Literature on a topic may be so extensive as to obscure trends with an overwhelming amount of information.
