Assessing regression to the mean effects in health care initiatives The regression to the mean concept Regression to the mean was first described over a century ago by Francis Galton (later Sir Francis) upon discovering that, on average, tall parents have children shorter than themselves and short parents have taller children than themselves [25]. RTM is the result of both random measurement error and extremity of scores from the mean [26]. A simple example of this occurs in measuring blood pressure or heart rate. Rarely are any two observations identical, even if taken minutes apart, due to natural biologic variability or measurement error. Bedtime Math Origami is creative math fun - Bedtime Math Origami, the ancient Japanese art of folding papers into shapes and artful forms, continues to evolve and attract new artists into the, ahem, fold. Origami requires spatial reasoning skills, thinking in three dimensions. It builds an understanding of geometric shapes and concepts. Origami is also creative and fun.

Kill Math Bret Victor / April 11, 2011 The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols. When most people speak of Math, what they have in mind is more its mechanism than its essence. This "Math" consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result.

Visual Processing: Cortical Pathways (Section 2, Chapter 15 The visual system is unique as much of visual processing occurs outside the brain within the retina of the eye. The previous chapter described how the light-sensitive receptors of the eye convert the image projected onto the retina into spatially distributed neural activity in the first neurons of the visual pathway (i.e., the photoreceptors). Within the retina, the receptors synapse with bipolar and horizontal cells, which establish the basis for brightness and color contrasts.

Tony Robbins UPW Explained, an NLP video analysis. Anthony J. Mahavorick, aka Tony Robbins is probably the most well known NLP student of all time. At one point in his truly remarkable career Tony was estimated to be worth $800 million and had an infomercial for his Personal Power product on TV somewhere in North America every 30 minutes. Tony learnt NLP back in the 80s and really did 'go for it' and apply what he learnt fully, fueling a career that went on to establish him and his "Mega" seminars as one of the top events to go to in the personal development world. He has coached or advised some of the top sports, business and politicians of our time.

Some Videos to Inspire at Back to School I wrote my post asking administrators to inspire us back to school simply because of my own hopes and dreams. I wrote it in the hopes that it would make someone think while they prepared their own meetings and activities, and it seems to have done just that. One question I have then gotten is which videos to show at back to school? And while I had a few in mind, I asked on Twitter and got many great responses. So in no particular order, here are some of my favorites. (I tried to pick shorter ones because I know my own attention span is limited at the beginning).

Infographic: See The Daily Routines Of The World's Most Famous Creative People We tend to imagine writers, painters, and composers burning the midnight oil, skipping meals, and working feverishly when true inspiration strikes. In fact, Tchaikovsky and Charles Dickens got plenty of Zs each night. Immanuel Kant made a point of visiting the pub every day. And Auden, Milton, and Beethoven kept precise work schedules.

Visible Learning Lecture by John Hattie These two videos show 30 minutes of edited highlights from a talk given by John Hattie. In part 1 Hattie presents influences with negative, or very low effect sizes related to students’ achievement. In part 2 John Hattie outlines some of the most successful influences to promote learning in schools.

Linear regression Linear regression is one of the most basic, and yet most useful approaches for predicting a single quantitative (real-valued) variable given any number of real-valued predictors. This article presents the basics of linear regression for the "simple" (single-variable) case, as well as for the more general multivariate case. Companion code in Python implements the techniques described in the article on simulated and realistic data sets. The code is self-contained, using only Numpy as a dependency. Videos Archives This presentation by John Hattie with a focus on professional development and the “Australian Charter for the Professional Learning of Teachers and School Leaders” was part of a one-day conference “Promoting a National Professional Learning System: a call to action”… In this video of the 2012 London Festival of Education John Hattie, author of Visible Learning, explores what the international research shows in relation to the panel’s question “What makes great teaching? The global view.” The second panelist Pasi Sahlberg,… In 2010 the University of Melbourne’s Graduate School of Education (MGSE) has appointed Professor John Hattie, author of “Visible Learning”, as Director of its research institute. In December 2011 Hattie lectured about “The future of measurement” during the MGSE’s Deans Lecture Series

Are We Handling The Bee Crisis All Wrong? On a crisp June morning at Knoll Farm, high above Vermont’s Mad River Valley, Charlie Nicholson stalked a bumblebee. He tiptoed behind the bee as it buzzed along a row of blueberry bushes, carrying a net that resembled a lacrosse stick. “The trick is to catch the bee without smashing the bush,” he said. “When I first started, I smashed a lot of bushes.” Digital Activities For Visual Literacy Visual literacy is the ability to construct meaning from or communicate meaning through information presented in the form of an image. While it may seem like this could only be applicable to the elementary student, visual literacy pervades all subject areas, disciplines, and grade levels in schools. From identifying patterns, to understanding modern art, to interpreting and creating graphs, visual literacy is one of the most widely important skills students should develop while in K-12 schools. Teaching and practicing visual literacy, as well as making students’ thinking visible to others, has never been easier. Many activities and methodologies exist for incorporating visual literacy and making thinking visible in the classroom, but now mobile apps are able to help support the practices of visual literacy and visible thinking even more. If you’re new to visual literacy or visible thinking, there are plenty of resources out there online to get you familiarized.
