Writing Well Matters

In his outstanding book, Writing Well, Mark Tredinnick (2008) offers the following insight:
“In these times, more than ever, we need a little depth and care, generosity and poise. We need a little perspective and honesty and restraint. And politically, a little low-voltage rage. We need, in other words, to rediscover the syntax of civility and the diction of democracy” (p. 230).

The “diction of democracy,” claims Tredinnick, is found in “the struggle to improve our sentences.” By equipping and empowering students as writers, we provide them with a critical tool for participation in democratic society. Being able to communicate well empowers expression. If a student believes his thoughts and opinions matter AND he possesses the means to communicate those thoughts and opinions, he is more likely to become a PARTICIPANT in democracy—someone with the means to change his standing rather than view himself as a victim of forces over which he has no control.

The benefits of learning to write also equip students for in-school success. Writing is a means of learning. Experts refer to this aspect of writing as “knowledge transforming”—“constructing ideas and images through writing” (Fearn & Farnan, 2001). In writing, “information promotes curiosity or speculation, and the writer uses the information and the curiosity to construct knowledge not originally accumulated” (p. 183-184).


Writing also develops important cognitive functions such as working memory. “Few activities are as cognitively demanding as writing” (Dingfelder, 2006). In fact, different writing phases engage different elements of working memory. While drafting obviously engages verbal working memory, planning a piece of writing actually engages spatial working memory. Writers “represent their ideas visually when trying to structure their essays,” notes neuropsychologist David Galbraith (Dingfelder, 2006). Spatial working memory empowers planning, verbal working memory empowers drafting, and both empower revision as writers evaluate and improve both idea-level structure and word-level details. Improving working memory abilities influences fluid intelligence, capacities “critical for wide variety of cognitive tasks” and “considered one of the most important factors in learning” (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). Teaching students to write may not only give them a means of constructing understanding, but may actually equip them for better or more efficient learning in multiple areas. Writing engages “more areas of the brain and involves them more intensely than any activity thus far investigated” (Houston, 2004, p. 8).


Despite these immediate and long-range benefits, our schools fail to produce writers. A recent study found that 70% of students in Grades 4–12 are considered low-achieving writers. Seventy percent! Researchers describe our current writing instruction as being stuck in the eighteenth century with little real relationship to actual writing. In other words, we are teaching something other than writing while we claim to be teaching writing. We must reclaim writing instruction and give it the time and energy it needs.


How should it be taught? The Center for Comprehensive School Reform and Improvement offers insights in its report “Writing Next,” and the Writer’s Stylus professional development and instructional program offers an “optimal mix” of effective methods.


If 70% of our students lack the “diction of democracy,” their influence could be limited. Let’s change the world through "
depth and care, generosity and poise," "perspective and honesty and restraint," and "a little low-voltage rage." Let’s develop writers!

Working Memory & Exercise

“Working memory is the gateway to authentic learning,” I wrote earlier this year. Without working memory activation, data will not proceed past sensory registration, preventing consolidation or construction of long-term memory. “Working memory is now known to be a busy, temporary workspace,” explains John Medina (2008), “a desktop the brain uses to process newly acquired information” (p. 124). And the deeper, more elaborate and personal that processing is, the greater the likelihood of data reaching long-term memory.

Recently, researchers at the University of Michigan seem to have discovered a means of improving working memory capacity. Subjects played a simple, Concentration-like card game and then completed tasks requiring fluid intelligence. Fluid intelligence is a cognitive ability that enables reasoning and problem-solving, especially when tasks do not correspond to previous experience. It plays critical roles in learning.


For the first time, this research team demonstrated not only that working memory capacity can be increased, but that it can also be transferred. And, as the subjects experienced more training, their working memory capacity, and thus their fluid intelligence abilities, increased. Additional training increased achievement (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008).


This represents important brain-related research for educators! If working memory capacity can be increased, our approaches to working with all learners, but especially struggling learners, may have powerful new options. Increasing working memory capacity can improve learning abilities and many school-related tasks, such as reading comprehension.


Combine this with the attention exercise is getting, and we may be on the verge of a new combination of activities that dramatically influence learning and brain functioning. In addition to Ratey’s recent book, John Medina (2008) discusses exercise’s impact on brain plasticity. “Physical activity,” claims Medina, “is cognitive candy” (p. 22). In addition to increasing blood flow to hippocampal regions of the brain, which are critical for memory formation, exercise increases Brain Derived Neurotrophic Factor, which keeps neurons healthy and more likely to form connections and encourages the formation of new neurons. Exercise can literally grow the brain!


What does this mean for educators? First, with new research suggesting working memory can be improved, methods for working with all learners should incorporate proven methods. We are not only teaching so students learn, we are teaching them how to learn. By improving their working memory abilities, we can increase their learning in all areas. Second, we can no longer ignore the influence of exercise. We MUST begin to take exercise seriously as a learning tool. However, allow me to clarify this: by exercise, I mean students actually engaging in regular (i.e., daily!) cardiovascular activity. Playing a softball game in gym class won’t cut it, and neither will pocket video games allowed in the playground. We need to be teaching students exercise habits that can last a lifetime.


Think of it—new neurons ready for use, current neurons ready to connect, and working memories operating optimally. What a learning environment we could create inside our students’ heads!


Now, where are my running shoes and that deck of Concentration cards?!?


Before concluding, I want to suggest a couple of resources. If you read only one teaching-learning related book this summer, make it John Medina’s Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School. (Order a copy here.) It’s easy to read and loaded with useful information. Dr. Ginger Campbell interviewed Medina on the Brain Science Podcast (download Episode 37). (The show notes for this interview are here.) The book is outstanding, and the interview is excellent. While at the Brain Science Podcast site, check out Episode 38, which features an interview with Jeff Hawkins, the author of On Intelligence. There's a great discussion of pattern recognition that will be of interest to readers with an interest in the Architecture of Learning. Enjoy!
