Lou Salza's curator insight, June 27, 3:27 PM

According to Thomas Mann: "Everything is politics".

According to the former Speaker of the U.S. House, Tip O'Neill: "all politics is local".  Thank you to the folks at Decoding Dyslexia all over the USA for their remarkably strong, successful efforts at advancing advocacy for dyslexics in State governments!--Lou 

 

Excerpt:

".....School reading or writing assignments may serve as triggers for intensely negative emotions of fear, stress, and anxiety, which in turn lead to memory and attention disruptions, which lead to physiological manifestations of that unease—and in some cases, catastrophic thoughts. By considering these cascading effects, we can understand why depression and, sadly, suicide rates for dyslexic children are higher than for the general population.

 

This sort of cycle is well-known in psychology, with the “anxiety cascade” being taught over many decades, even in basic psychology courses. The diagram included in this article adapts that cycle to specifically address the pattern observed in dyslexic children.

Because of this “Vortex of Dyslexia,” early intervention for children is critical. Dyslexia is in many ways an invisible struggle. If dyslexic children are not properly evaluated and treated what may seem to outsiders as “simple” reading and writing difficulties can grow into far more significant psychological or physiological problems..."

Frontiers | Developmental dyslexia: dysfunction of a left hemisphere reading network | Frontiers in Human Neuroscience

This mini-review summarizes and integrates findings from recent meta-analyses and original neuroimaging studies on functional brain abnormalities in dyslexic readers. Surprisingly, there is little empirical support for the standard neuroanatomical model of developmental dyslexia, which localizes the primary phonological decoding deficit in left temporo-parietal regions. Rather, recent evidence points to a dysfunction of a left hemisphere reading network, which includes occipito-temporal, inferior frontal, and inferior parietal regions.

Tracking Dyslexia In The Preschool Brain @TuftsGSAS @MaryanneWolf_

Tracking Dyslexia In The Preschool Brain @TuftsGSAS  @MaryanneWolf_ | Dyslexia Today | Scoop.it

Maryanne Wolf, director of the Center for Reading and Language Research at Tufts University, described the work as “amazing.”

“It shows that this brain is differently organized for written language before reading ever occurs,” she said via e-mail. “It is like a missing piece in our understanding of dyslexia.”

Identifying the signs of dyslexia in the brain helps destigmatize the condition, said Wolf, author of “Proust and the Squid: the Story and Science of the Reading Brain.”

“One of the problems in dyslexia is people are saying it doesn’t exist,” she said. “When you look at these brain images you know it exists.”

Wolf said she’s optimistic that dyslexia will eventually be diagnosed before a child falls too far behind. In the meantime, she said, teachers should be better trained in how to identify dyslexia and how to help children who are struggling to read.

“We have to get our professional develop commensurate with our knowledge base,” she said.

How Homework Works In Finland (Hint: There Isn't Any) - By Katie Lepi, Edudemic

How Homework Works In Finland (Hint: There Isn't Any) -  By Katie Lepi, Edudemic | Dyslexia Today | Scoop.it

When we talk about how our education system is failing our students, there are a lot of different options presented on how to ‘fix’ it. Everyone has an answer, a promising new way of thinking, a potential magic bullet. Inevitably, we also examine school systems that are working as a part of investigating what to do or not to do with our own.…

Lou Salza's curator insight, July 28, 12:37 PM

The research in the US is murky at best, but commonsense and the data suggest we put too much emphasis on compliance with excessive homework requirements. Grading practice problem sets in math for example troubles me because practice should not be evaluated except as it proves an effective path towards mastery. Likewise, giving students failing grades for failing to hand in homework when they have mastered subject matter is irrational. --Lou

 

Excerpt:" ....And one of those that is working and is almost always mentioned is Finland. Their students regularly top the charts on global education metrics despite a lack of homework and more away-from-the-desk time during the school day. No homework is a pretty drastic measure in most people’s minds, so how does it work?

The handy infographic below takes a look at why homework doesn’t seem to be a necessity given the structure of the rest of the system. Do you think a Finland-esque education system would work here in the US? Why or why not? Weigh in by leaving a comment below, mentioning @Edudemic on Twitter or leaving your thoughts on our Facebook page.

And I quote: (report from the National Scientific Council on the Developing Child)

 "In terms of basic brain functioning, emotions support executive functions when they are well regulated, but interfere with attention and decision making when they are poorly controlled."  

Moral? Lead with the heart. Get  your head due north –then and only then, Teach! --Lou

 

Excerpt: "...Neuroscience, too, has offered evidence to support a holistic message about cognitive, social, and emotional development. Recent scientific advances have led to rejection of a cognitive versus affective framework to describe human cognition. Evidence shows that the prefrontal cortex, considered the center of higher-level cognition in the brain, also plays a dramatically important role in emotion processing and regulation. Thus, the operation of the brain is more like an orchestra than a number of soloists. This paradigm-shifting evidence has forced us to rethink the relationship between reason and emotion. Not only does academic learning depend on social and emotional skills, but also it is virtually impossible to disentangle the two. A report from the National Scientific Council on the Developing Child put it this way:

When feelings are not well managed, thinking can be impaired. Recent scientific advances have shown how the interrelated development of emotion and cognition relies on the emergence, maturation, and interconnection of complex neural circuits in multiple areas of the brain, including the prefrontal cortex, limbic cortex, basal forebrain, amygdala, hypothalamus, and brain stem. The circuits that are involved in the regulation of emotion are highly interactive with those that are associated with “executive functions” (such as planning, judgment, and decision making), which are intimately involved in the development of problem-solving skills during the preschool years. In terms of basic brain functioning, emotions support executive functions when they are well regulated, but interfere with attention and decision making when they are poorly controlled...."
