Edward Hessler

Occasionally I wonder how many K-12 public schools, districts, teachers, administrators and students are there in the United States? What are the top ten largest school districts? How long do administrators serve? Etc.

Maya Riser-Kositsky who writes for Education Week, American Education's Newspaper of Record, has spent some time and labor finding these kinds of data using sources from the U. S. Department of Education, National Center for Eduction Statistics; U. S. Department of Commerce, Census Bureau; The Broad Center; Education Week Research Center, 2018.

So if you are interested in what she found here you go

Ms. Riser-Kositsky has made this an easy read.

And if you are interested in some similar data points for Minnesota, this summary from the Minnesota Department of Education should help.

--I love Cerion with all my heart and mind.--Stephen Jay Gould*

On January 4, 2019, the Hawaii Department of Land and Natural Resources announced a significant death. Another species has disappeared from the planet. The last known Achatinella apexfulva in the Hawaiian Islands, 'George,' died on New Year’s Day, 2019. George was approximately 14 years old and his name was derived from the Pinta Island Galapagos tortoise, 'Lonesome George,' also the last of its species.

George died in captivity, the last of ten who it was hoped would produce offspring so that a small population would grow.

The news release also notes that Achatinella apexfulva was the first of over 750 species of land snails from the Hawaiian Islands described in western science. The first mention dates back to at least 1787 when Captain George Dixon was docked on O‘ahu and was given a shell on a lei.  These snails were once common on O‘ahu in the Ko‘olau Mountains and were used heavily for lei making as access to them was much easier at lower elevations. (my emphasis)

Land snails have contributed to our understanding of biological evolution, namely the importance of geographical separation in speciation. Much is owed to the pioneering work of missionary and evolutionist, John Thomas Gulick (13 March 1832 - 14 April 1923), who was born in Hawaii, on the island of Kauai. He was the first to  note the role of geographic isolation in species formation. 

Gulick can be credited with discovering 'intra-island endemism,' i.e., the ecological state of being unique to a particular place. In this case, on an island with the endemic (unique) species being found in the valleys separated by ridges.

Rebecca Rundell wrote a splendid review of Gulick, including his life, and his work which was published in the American Malacological Bulletin (2011). This paper provides insights into the nature of science (e.g., naturalists v. experimentalists, the fortuitous nature of discovery, being in the right place, taking advantage of a general interest in shells) and the history of science (how ideas change and reasons for those changes). In her article, Rundell discusses an early debate on mechanisms for evolutionary change. In this particular case it was natural selection or geographic isolation (now both are regarded as mechanisms). The paper includes an interesting map.  

*Cerion was a genus of tropical land snails from Bermuda and islands of the Caribbean that the late paleontologist and evolutionary biologist Stephen Jay Gould studied.

Poverty
Edward Hessler

I've watched a short video from the BBC a couple of times and can't shake it.

It is about how people find a way of making a living under conditions that are nearly unimaginable

One obvious contrast is Bachman-Turner Overdrive's Takin' Care of Business and this one, two ways of making the morning commute..

We live in a wealthy world with more poverty than I will ever know. Our comfort allows us to think about and experience that world so differently.

A Change In The Climate of Climate Education

Climate Change
Edward Hessler

From Glenn Branch of the National Center for Science Education comes some news about climate change education and schools.

Many states already require the teaching of climate change in effect, through its inclusion in their state science standards, but not as a matter of statute. A bill, HB 5011 introduced in Connecticut would amend the Connecticut General Statutes to require "that the science curriculum of the prescribed courses of study for public schools include the teaching of climate change and that such teaching begin in elementary school."  HB 5011 is not the first such bill in Connecticut.

A Winner Is Announced

On December 8, 2018 I posted an announcement from the American Academy of Poets about the first-ever National Poetry Contest for Students.

The winner was announced a few days ago. Julia Wang is in tenth grade at Lynbrook High School, San Jose, California.

You may read about the contest, Wang's artistic statement about the poster, the judges and also see the poster here. You can request one, too.

As I said before, I think this was a difficult choice or at least it would have been for me.

I ordered one but my past experience with poster offers from the American Academy of Poets for National Poetry Month is mixed. Sometimes I get one; most often I don't. Still I think it is always worth the try--envelope and stamp free although there is an environmental cost.

Do Things Ever Change?

Kenneth Weiss is an emeritus professor (anthropology) at The Pennsylvania State University. Now that he is retired he posts less frequently on his blog The Mermaid's Tale but I still check it frequently.  I read Weiss for his thoughtful, critical comments on big science and genome association studies (GWAS).

Near Christmas 2018 Weiss wrote a "post as a kind of reminder, of who we are relative to who we fancy ourselves to be, relative to who we once were." The centerpiece was two pages from The Malay Archipelago (The Races of Man) by Darwin contemporary and co-discoverer of the theory of evolution, Alfred Russel Wallace, a book I've never read although I've read excerpts. The book concludes with a devastating critique and condemnation of his home country, England. The criticism still resonates with a truth we don't care to confront. Unfortunately, there have been almost no changes.

Compared with over wondrous progress in physical science and its practical applications, our system of government, of administering justice, of national education, and out chief energies to the utilizing of our knowledge of the laws of nature with the view of still further extending our commerce and our wealth, the evils which necessarily accompanying these when too eagerly pursued, may increase to such gigantic dimensions as to be beyond our power to alleviate.

We should now clearly recognize the fact, that the wealth and knowledge and culture of the few do not constitute civilization, and do not of themselves advance us toward the "perfect social state." Our vast manufacturing system, our gigantic commerce, our crowded towns and cities, support and continually renew a mass of human misery and crime absolutely greater than has even existed before.

PreSchools: Online or Offline

Early Childhood

I'd never heard of or given any thought to the idea of online preschools. What? 

Turns out that it is a growing industry (calling it an industry seems a fair characterization because it seems to me an industrial model with inputs (young, curious kids), assembly (in the form of drills, rote learning) and outputs (a narrow set of skills).). 

Try to let the idea of a screen-based education for young children sink in. It doesn't compute. So what is the temptation?  It is cheap. It is a money-maker for the for profit-based companies (the "pre-K market" is in the neighborhood of $70 b per year, that's a big B).

Nancy Carlsson-Paige, Lesley College (now a professor emerita) an early education expert and cofounder of the not-for-profit, Defending the Early Years. In a recent column in EdSurge, Professor Carlsson-Paige writes that "it is a sorry substitute for the whole child, play-based early childhood education that all young children deserve to have." (My emphasis).

I quote from Carlsson-Paige whose child-centered prescriptions makes sense to me.

Young children don't learn optimally from screen-based instruction. Kids learn through activity. They use their bodies, minds and all of their senses to learn. They learn concepts through hands-on experience with materials in three-dimensional space. Through their own activity and play, and their interactions with peers and teachers, children build their ideas gradually over time.

Many of the online pre-K programs encourage parents to put their kids in front of computers to do academic drills even if they are in a preschools setting.But if parents really want to help their kids get ahead, whether they are in brick and mortar preschools or not, they would do best by reading lots of books to their children, having ongoing conversations with them, listening and askng open-ended questions that help kids think.They might tell them stories, provide a place for children to play and materials to play with, such as building blocks and art materials that allow them to explore number relationships and use symbols.

Some key words/phrases: activity, whole body, sensory, 3-D space, interactions with materials, others and teachers, idea construction over time, conversation, read-alouds, listening, asking open-ended questions, stuff to play with (blocks are one of the greatest toys ever invented), exploration.


And speaking of read-alouds, Indianapolis Colts quarterback Andrew Luck was the subject of a short CBS This Morning profile on reading about his love of reading and of sharing that love with young children. Luck apparently is known as the "NFL's unofficial librarian." He likes it. One takeaway was that the children appeared much less interested in Luck's quarterback/football cred than in being read to.

I link you to two kinds of early childhood schooling mentioned by Professor Carlsson-Paige: Reggio Emilia and Waldorf in the event you've not heard of them.
