EACH of three respondents to my article found some value in educational neuroscience, and none of them found any factual errors. Our differences are to be found in points of emphasis and degrees of caution. I am grateful for each response and value comments. Robert Sternberg raised excellent points. One was or we are asking right questions in education. I respect his right to question very issues we are raising in education. He has invested much of his career in an important pursuit--understanding, defining, and applying new ways of thinking about intelligence in a less biased and far more practical way. I am always going to support that effort. He's right, too, that intelligence can and should be measured in a much better fashion than it now is. On my top-three list of important priorities, I would certainly include assessment. Sternberg's second issue with brain-based education is there are any educational implications to research but whether [educators] can take such research and derive educational implications. If not, then we have metaphor, but we do really have At least, he continues, not kind of science that prescriptively is going to help us design educational interventions. Because Sternberg believes that it is unclear there are implications of brain research for education, he argues that we would do better to focus lion's share of our attention on many pressing issues that demand immediate solutions. He concludes by suggesting that it may be better to leave the brain issue as one to be dealt with later, in longer term. That kind of thinking I do have a problem with. Brain research isn't going away; it's increasing and will continue to do so. So we educators need better tools to deal with it. The research coming out is no trickle; it's a flood. For educators to ignore research on brain would be like ignoring melting of polar ice caps because we've got to deal with famines and wars first. After all, one could argue, we have research on practical and prescriptive interventions for starvation and war. Yet research on global warming is still fairly new and far from perfect. Nevertheless, I would argue, along with thousands of climate scientists, that global warming evidence is strong enough to allow us to move forward--even though it's unequivocal. Brain research, too, faces many unsolved mysteries. We all acknowledge that we have far to go, but we do know enough to move forward. Sternberg wants unequivocal findings, but we may never have them. Nearly every study, in nearly every discipline, from physics to sociology to nutrition to neuroscience, has been overturned, broadened, narrowed, made irrelevant, dismissed, politicized, or redefined in last 100 years. That's nature of science. In medicine, only a few years ago, it was standard procedure to give many heart patients a stent to help widen passage of blood through arteries. A few years ago, stent implant procedures were considered so solid that Vice President Dick Cheney's heart operation was labeled routine. Now, new evidence suggests that those with stents may live no longer than those who don't get one, but they pay much more and face higher risks. Were original findings about using stents unequivocal? In field of educational neuroscience, there have been countless errors of enthusiasm made in interpretation of research and its development into classroom applications. But unlike mainstream medical profession, which claims to act on unequivocal findings, we are putting thousands of lives in jeopardy every year when we act on findings that are equivocal. I don't worry about those with questions; I worry about those who know all answers. Neuroscientist Teri Jernigan of University of California, San Diego, sees nothing wrong with trying out new ideas, as long as there's no downside risk to them. …
