I first became aware of Eric Jensen's work at a teacher's training. I decided right then and there to get my hands on any works by this author. And it was well worth it.
Here is the blockbuster "announcement." According to the author, not only is "nature" greatly involved in brain development, but experiences could actually alter DNA in the brain--positively or negatively! He goes into much more depth in this area than I could summarize here--which is why you will have to garner your own copy, and grab an easy chair!
The author lays out the effects of poverty on a child's brain--from birth, and throughout the child's lifetime. The detailed description-from gritty depictions of urban life where lower socioeconomic youth are more likely to be exposed to (and affected by) lead poisoning, or to live on or near toxic waste sites, to impaired and retarded brain development brought on by poor nutrition. But all isn't lost (he asserts)--the potential for the brain to grow new neurons, increase connections, and-YES- IQ - is much greater than scientists had ever before thought possible.
The author discusses study after study that proved his assertion--and they are deliciously satisfying. He mentioned how we previously believed that little could be done to raise intelligence beyond what one was born with-but how we are discovering a myriad of changes (in nutrition, environment--and SCHOOL ENRICHMENT)=that could result in IQ increases of 19 points or more. He further made the very encouraging point that the potential for increasing brain growth (and overcoming deficits) is actually significantly GREATER among poor students. He went further and mentioned that there are actually many more gifted and talented students among the lower and middle classes--than there are among the upper classes. As you might well imagine, it has turned many sensibilities--on their prophetic heads!
There are many references to studies and findings regarding disabled and special-needs children, as well--particularly their overrepresentation among Black students. The author proposes and outlines a sustained program of enrichment (beginning as soon as possible) to counter the effects of poverty. He starts with comparative studies of the brains of rats--and ends outlining sustained increases in intelligence, vocabulary-and better life outcomes-for the vast majority of students who were fortunate to enjoy a program of enrichment; these materialized from long-term studies.
I will take a moment here to outline some of the claims of neuroplasticity--the ability of the brain to overcome injury, prior retarded growth, etc., for much longer than ever previously thought, and up into ages not previously known. Saliently, he mentions the role of exercise and music in brain development and enrichment--especially in grade school.
There is so much to unpack here, that I find myself returning to edit this review--here are a few more nuggets. The author points out that lower socioeconomic children-who are much more highly likely to have witnessed and been affected by trauma and/or nutritional deficiencies-display a greater incident of ADD and ADHD. This-combined with my later citation of a greater exposure to lead (which causes mental retardation) and greater likelihood of living on or near toxic waste sites-result in an unfortunate cornucopia of barriers to learning effectively. Enrichment, the author asserts, is the antidote to this distressing situation.
The author talks about 3 methods of enrichment--bottom-up, combination, and top-down. The bottom-up approach involves the classroom teachers taking action without the involvement of administration--applying the methodology his or herself, but also educating parents on creating and supporting enrichment at home. The combination approach involves doing this with some support from administration. Lastly, the top-down approach involves heavy investment and involvement by administration in coordinating and implementing a school or district-wide enrichment program (including parent education.)
The author also points out that *ALL* children need enrichment. He states that even very gifted children could get bored, tune-out, and even act-out. He goes on to say that gifted children are often not recognized due to various factors--and that they might also not be found to have learning disabilities (and they could be in both categories simultaneously.)
I want to highlight a crucial point made by the author. To be successful in engaging students (especially the poor and learning-disabled), teachers must create an engrossing climate-and program of enrichment-that is *CONTRASTED* with the home learning situation, which is suboptimal for the student populations examined--there must be CONTRAST. The climate must also be constrasted with past, stale, ineffective methods of learning. He asserts that BOREDOME ITSELF could result in brain insults in the loss of neurons (if I recall correctly), connections, and myelination (the fatty insulation covering neural synapses connecting neurons that aid in speeding up neural impulses.)
The revolutionary claim the author makes is that *ALL* students should have IEP's-individualized learning plans-not just special-needs students. He states that each student's education should be customized, they should not be compared to other students (but only to their own identified goals and progress), and that standardized testing should be deemphasized (and/or eliminated.) He goes on to say that students should not be in "grade 3" or "grade 10," but should move on to the next concept as mastery is achieved. It's a lot to take in, but he asserts that the maintenance of these plans would actually result in *LESS* work for teachers. He also points out that special-needs students with IEP's are better-supported than mainstreamed students--with smaller learning communities, constant feedback, and learning teams involving teachers, parents, specialists, etc.
The author asserts that your brain is a "use it or lose it affair," and that this is especially important in the first 3-5 years of life. He states that plopping a toddler in front of a "learning" DVD, TV, etc., is *NOT* enrichment. Enrichment involves active participation with hands-on paraphernalia, exploring parks, discovery, seeing the gleeful facial expressions of parents (who are modeling emotions that are beyond the 8-9 we are born with), making connections, etc.--things that busy parents these days have lost sight of. He also points out how children in poverty have much less oppportunity to explore--being in smaller homes, dangerous neighborhoods, etc.
As a teacher, this book invigorated and inspired me--and gave me great hope. It created raw fuel for further reflection--and suggested several other books for further study. I can't recommend it enough. In short, it's "literary crack." :)
