If the Earth Stood Still

If the Earth Stood Still | Prendi eLearning Literacy & Humanities Technology | Scoop.it

"The following is not a futuristic scenario. It is not science fiction. It is a demonstration of the results of an extremely unlikely, yet intellectually fascinating query: What would happen if the earth stopped spinning?  ArcGIS was used to perform complex raster analysis and volumetric computations and generate maps that visualize these results.


Via Seth Dixon
Melissa Marshall's insight:

How interesting! The detailed GIS is fascinating and although an unlikely scenario, is great for discussion and deeper thought. You could discuss with students how the world would cope or what sort of device could start it spinning again...?

I love a good "what if?" question and this one (including the GIS model-based analysis) is fascinating.

What a fascinating question, answered as a visualisation: What would happen if the earth stopped spinning? ArcGIS was used to perform complex raster analysis and volumetric computations and generate maps that visualise the results.

......... 

Most scientists agree that the solar day (related to the speed of rotation) is continuously getting longer. This minimal increase of the day length is due mainly to the oceanic tidal friction. When the estimated rate of the slowdown was projected back to past geologic eons, it showed that the length of a day was several hours shorter than today.

Consequently, during the Devonian period (400 million years ago), the earth rotated about 40 more times during one revolution around the sun than it does now. Because the continents have drifted significantly since that time, it is difficult to make estimates of the land versus ocean outlines for that era. However, we can be certain that—with a faster spinning speed in the past—the equatorial bulge of oceanic water was much larger then than it is today. Similarly, the ellipsoidal flattening of the earth was also more significant.

The influence of the rate of the earth's rotation has a dominant effect on the geometry of the globe, in terms of the globe's overall shape as well as the outline of the global ocean. The earth's physical relief is only a secondary factor controlling the delineation of oceans. The slowdown of earth's rotation will continue for 4 billion years—as long as we can imagine. The slowdown infinitesimally—but steadily—changes the globe's geometry and makes it dynamic. The net result of these dynamic adjustments is that the earth is slowly becoming more and more like a sphere. However, it will take billions of years before the earth stops spinning, and the gravitational equipotential creates a mean sea level that is a perfect sphere.

Shanelle Zaino's curator insight, October 22, 2014 3:10 PM

With the increasing amount of information online it can be misleading at times. I do believe this is a useful collection of maps however I feel people looking at it might get trapped in a pitfall. After looking at these 40 maps a person could feel that this is all there is to know about this subject. Yes it is informative to have this information together but it should just be the start of the conversation not the end. So often we want quick google searches with definite answers,

when some topics require a lot of research from different sources. The reader needs to make up their own pool of knowledge.

How to Infuse Digital Literacy Throughout the Curriculum

How to Infuse Digital Literacy Throughout the Curriculum | Prendi eLearning Literacy & Humanities Technology | Scoop.it

"So how are we doing on the push to teach “digital literacy” across the K12 school spectrum? From my perspective as a school-based technology coach and history teacher, I’d say not as well as we might wish – in part because our traditional approach to curriculum and instruction wants to sort everything into its place."

 


Via Beth Dichter
Melissa Marshall's insight:

A very interesting article that examines whether digital literacy is a surface approach, or something understood clearly by students. I think we could do it a little better, and this involves some extra awareness of these teaching moments when they arrive! For instance, I use the first presentation-style assignment for my Year 7s to teach about plagiarism and referencing online sources.

Beth Dichter's curator insight, March 27, 2014 9:14 PM

How often have you heard the term digital native or digital immigrant? Are our students digital natives because they were born after digital items were widely available? Does this factor mean that they understand how to use these tools effectively and that they are digitally literate? For me the answer to that is that they do not fully understand how to use digital tools effectively and they are not digitally literate. This is something we need to teach them.

This post does an excellent job looking at this issue. Specifically it looks at these areas:

* Students must learn how to evaluate online content - Think of this as a research skill.

* Students must be able to engage with others online and communicate - Think of this as a communication tool.

* Students need to learn how to create and projects can be digital.

These three areas come together and create the skill sets needed to digitally literate. More information is available about this in the post.

And if you happen to live in the New England area you might consider checking out the Massachusetts New Literacies Institute that will be taking place in at the Kittredge Center in Holyoke, MA from July 8 - 10. Information for this may be found at http://mnli.org/. This institute looks at three cornerstones: Online Content Reading, Online Collaborative Inquiry and Online Content Construction "preparing future-ready teachers."

The Science of Storytelling

The Science of Storytelling | Prendi eLearning Literacy & Humanities Technology | Scoop.it

Many studies show us that our brains prefer storytelling to facts.When we read facts, only the language parts of our brains work to understand the meaning. When we read a story, the language parts of our brains and any other part of the brain that we would use if we were actually experiencing what we’re reading, light up.This means that it’s easier for us to remember stories than facts. Our brains can't make major distinctions between a story we’re reading about and something we are actually doing....

Here's how it works; students sign-in (email is not required) to find the worksheets that you have assigned to them. The worksheets contain spelling and grammar errors that your students have to identify and correct. Students submit their corrections and Quill shows them how they did by showing what they did correct and what they should have corrected. An explanation accompanies each Quill correction."

Melissa Marshall's insight:

An excellent infographic on the value of handwriting. This page explains why handwriting helps our brain learn at a faster rate than typing, and can allow better recall. They also lit apps that can promote handwriting and allow natural writing on a device such as the iPad. There is a lot of debate about whether writing is losing its significance - I think it can be enhanced by technology. If I take notes of a presentation on paper, that is the only format my knowledge takes. If I type my notes, I can quickly rearrange my ideas into lists, mind maps, colours and more. Perhaps it is the way we think and organise the info behind our notes, and less of the notes themselves, that provide the key difference for whether we learn effectively or not?
