Digital textbooks reduce costs, but do they also reduce learning? | Get Schooled - Atlanta Journal Constitution

Photo: Rick Diguette
Rick Diguette is a frequent Get School contributor on higher ed issues. He is a local writer who retired from college teaching last year.

In this essay, he examines whether the cost savings offered by digital college textbooks – electronic or e-books -- outweigh the potential drawbacks. 

Diguette cites the research showing students just don’t learn as well from screens as they do the printed page.

Maureen Downey, Education columnist says, It costs a small fortune to go to college these days

To save money, colleges are moving away from textbooks to e-books But a retired college professor says studies suggest that for reading assignments of more than a page in length students grasp more from a paper text than a screen.

According to the most recent annual report of the Institute for College Access & Success, by the time four-year college graduates walk across the stage to receive their diplomas, they owe on average almost $30,000 in loan debt. As for all those students who drop out before earning the right to take that walk, they typically owe about $14,000. 

That’s why private and public institutions are under increasing pressure to reduce their students’ financial burden. Some have cut tuition costs and stepped up alumni fund-raising efforts, while others have expanded student access to scholarships and grants that don’t have to be paid back. It remains to be seen if these measures will begin to erode the mountain of debt that Forbes magazine has dubbed America’s $1.5 trillion crisis.

Another cost-cutting measure involves the lowly textbook. Students attending expensive private colleges are just as likely as their peers at public institutions to have low-cost, or even no-cost, e-textbook options in some of their classes. The differences between their centuries-old hardcover forebears and today’s e-textbooks are obvious: traditional textbooks weigh a lot more, typically cost a lot more, and are a lot more likely to get lost, damaged, or stolen. E-textbooks, on the other hand, are so easily accessed with a laptop, tablet, or cell phone that they can look like a no-brainer. At least until you do a little digging. 

Studies dating back to the early 1990s have suggested that for reading assignments of more than one page in length ― there will be plenty of those in college ― students appear better at comprehending complexity when reading a paper text as opposed to a screen. These same studies provide another way to look at this: while many of today’s so-called digital natives prefer screen reading and do it faster than when reading paper texts, their understanding of what they’ve read may not be nearly as deep.

Eastern Kentucky University Professors Connect With Generation Z | WEKU

Faculty at Eastern Kentucky University are finding ways to connect with students known as Generation Z, reports Cheri Lawson, Morning Edition Host and Reporter.

EKU's Dr. Beth Polin prepares students for exam.

The Gen Z-ers are sometimes referred to as “digital natives.”

On a recent Tuesday at EKU, Tanner Gillispie wearing a plaid shirt and sitting in the third row of Dr. Beth Polin’s class is taking detailed notes for an upcoming exam.

Tanner’s using a pen and notebook, rather than a computer or his phone to take notes because Dr. Polin insists. Tanner says when he’s not in class he’s looking at his phone a lot.

Tanner says, “Outside of the classroom setting I’m probably on my phone, I’d have to say thirty or forty times an hour. Talking about a day I’d say I probably look at my phone seven or eight hundred times.”


The 21-year- old is part of Generation Z, people born from 1995-2010. This generation spans most of an entire educational system.

The Generation Z-ers characterize themselves as loyal, responsible, and determined according to Dr. Corey Seemiller, generational researcher, associate professor at Wright State University, and author of 4 books about Generation Z. Seemiller says, “This is the first generation that has grown up where before they were even born they had a digital footprint.”...

There are strengths and weaknesses with every generation says Assistant Professor of Management at EKU, Dr. Beth Polin. She says this generation tends to trade accuracy for speed since they communicate more through social media. Some people see continuous engagement with social media as a weakness. She says, “The way this translates into a strength is: they want to be involved. Every generation has its big world problems that have to be solved. They don’t want to miss out on being part of the solution.”

How Fibonacci Retracement is used in Forex Trading | Basics & Industry - Forex Crunch

In the following post from TradeFW.com broker, you will find out what is Fibonacci Retracement and how to use it for effective trading. 
 


As a forex trader, something which you will doubtless encounter at many points throughout your trading career is Fibonacci retracements. These are a key technical indicator used to identify levels of support and resistance. It is one of the most fundamental and simplistic charting techniques which can be easily implemented by all levels of forex trader.

The History and Fundamentals of Fibonacci Retracement
Fibonacci retracement is based on a sequence of key numbers which were identified in the 13th century by the Italian mathematician, Leonardo Fibonacci. This number sequence and specifically the relationship of the numbers to each other when expressed as a ratio are a key to identifying support and resistance levels in trading.

The sequence of numbers set out by Fibonacci, and adapted by modern mathematicians is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. As we can see from a more detailed analysis, each number is the sum of the two preceding numbers. This continues infinitely and is key to deducing the ratios used in retracement.

The Fibonacci ratios are, 23.6%, 38.2%, 50%, 61.8% and 100%. These are used hen dividing the vertical distances on a chart between two points to create a Fibonacci retracement. The “Golden Ratio” is derived by dividing one number in the sequence by its following number. This will always equal approximately 0.618. The other key points are derived in a similar fashion.

Top forex traders who engage in technical analysis, will plot these lines horizontally across a chart in order to identify the key points of support, where the market may retrace to, and levels of resistance which may be reached in future movements...

Conclusion
Ultimately, whether or not traders choose to agree on its effectiveness, Fibonacci retracement is one of the most implemented technical analysis techniques among forex traders today. Within any high-quality forex trading educational program, it is one of the fundamental tools which you will learn how to use.

With a solid foundation in Fibonacci retracement, you can set yourself up to continue learning about other more advanced technical analysis tools. This is a learning process, which, regardless of how you feel about it, can only enhance your knowledge and potential to emerge profitably from the lucrative forex market.

More mathematical conundrums solved with mental arithmetic and poetry too | Lifestyle - Belfast Newsletter

The Reverend Isaiah Steen
Regular readers of Roamer’s page have by now become quite well acquainted with the Reverend Isaiah Steen, a Presbyterian minister, mathematician and author of a once-popular school text book called Steen’s Mental Arithmetic.

Frontispiece of the Reverend Steen's book

He published his widely-referenced book, followed by several additional print-runs, when he was a teacher in the Royal Belfast Academical Institution in 1842.

The book is a rich mine of information about all things mathematical, introducing formulas, equations, procedures and techniques for solving numerical problems “in the mind” the author explained “without the use of paper or slate, or anything else on which to perform the operation.”

Some of Rev Steen’s mathematical manipulations seem almost magical today, relying on brain-power rather than our ubiquitous, battery-powered calculators that effortlessly multiply, divide, add and subtract.

Work Out The Number of Shopping Days Till Christmas (2019!)

It’s probably this dependence on modern technology that baffled some folk when faced with the Rev Steen’s Table of Interest, a little mathematical chart that was shared on this page last week.

Based on Professor James Thomson’s calculations, another of Inst’s mathematics doyens, Rev Steen explained in his book that the Table of Interest “may be useful in finding the number of days from any day of one month to any day of any other month.”...

My apologies – I only included Rev Steen’s above-mentioned introduction to the chart last week and omitted his demonstration of how it works.

Rev Steen offered four examples to aid his readers, preceded by a general rule – “the table gives the days between any day of any month and the same day of any other month, which must be increased or diminished by the days in excess or defect.” 

In other words – if you want to know the number of days between today, December 12, and July 12, you just need to look at the December column of the chart and move horizontally across to where the vertical July column intersects. There you’ll find 212 – hey presto, the number of days between now and the 12th! 

I’ve checked it on my calculator and Rev Steen is absolutely right, but that’s from the same date this month to the same date in July.

Are These Incredible Historical Coincidences Actually Due to Synchronicity or Mathematical Probability? | Unexplained Phenomena - Ancient Origins

Coincidences are a concurrence of circumstances which are so unpredictable that they often become associated with the supernatural and paranormal, insist Ashley Cowie, Scottish historian, author and documentary filmmaker.

Tomb of Galileo Galilei in Santa Croce , Florence, Italy. Stephen Hawking was born on the same day Galileo died, 300 years later – a strange historical coincidence?

History is composed with brilliant acts of skill and is also full of bizarre ‘coincidences’ that often seem so incredible that many people have been convinced higher powers were at play.

Mathematicians describe coincidences as probabilities and deem them as inevitable, meaning they can be given odds of occurring. It is when the odds of an occurrence are highest that events are thought of as being coincidental, and if the odds are through the roof then some events can appear almost miraculous.

So far as mathematicians and near miracles are concerned, Stephen Hawking, one of the greatest scientific minds in all of history, would have struggled to work out the chances of his own birthday, January 8, 1942, falling on the 300th anniversary of the death of another great scientist, Galileo Galilei. What is more, his death occurred on Einstein’s 139th birthday, March 14, Pi day, when the calendar reads 3.14.

Before we look at what exactly a coincidence is, scientifically, and why they occur so frequently, let’s first look at some of history’s most perplexing and apparently extraordinary coincidences, that seem to stretch mathematical probability to its very extremes.

Why reading 100 books a year won’t make you successful | Medium.com

Originally published at www.jotform.com.

Reading is trending, notes Aytekin Tank, Editor of The Startup and JotForm.


The internet’s taken something uncool and given it a makeover.

Reading is the new kale: worth stomaching because it’s Good For Us.

So good, in fact, that we should do as much of it as we can. More is more! Everyone should be reading one book a week — no, wait, one book a day.

That’s why Mark Zuckerberg, Bill Gates and Elon Musk are successful, after all.
The more we read, the smarter we’ll get.

But where to find the time? We have to do it faster, faster, and faster still!...

As the professor and eye tracking researcher Keith Rayner explains, techniques like simultaneously reading large segments of the page aren’t biologically or psychologically possible, due to the limitation of our foveal viewing area.

An entire page can’t be read at once. Zig-zagging down one page doesn’t work. The human eye just isn’t up to it...

And according to UCLA psychologist Patricia Greenfield, when the brain skims, less attention and time is allocated to slower, more time-consuming processes, like inference, critical analysis and empathy.

In other words, we aren’t giving ourselves enough time to grasp complexity or develop opinions of our own...

Why do we read, anyway? 
Consider three types of reading:
  • The first is passive. Scrolling on Facebook, flicking through a magazine in a doctor’s room, tapping away on Twitter. This reading happens to you. 
  • The second is practical. Reading for a purpose. Because we want — or need — to learn something. At school, college, or for personal improvement. 
  • The third is pleasurable. Not just fiction or magazines or fluffy escapism. Reading for pleasure doesn’t have a category: it’s subjective. It happens when something makes you tick: an article, a novel, an autobiography.
Reading because you want to, not because you feel you should.

Learning, design and technology grad embraces online learning to help students | Penn State News

Jessica Buterbaugh, marketing communications specialist for the College of Education says, After 10 years working as a technology director and teacher for a small, rural school district, Marty Petrosky knew the best way to help his district was to return to school. 

Marty Petrosky, left, and his family — daughter Mariya, son Kai and wife Heidi (class of 1995) — have always been Penn State fans. Now, Petrosky can also say he is a proud alumnus.

Completing a graduate program is rigorous and time-consuming. Just ask Marty Petrosky, who returned to being a student after spending more than a decade educating students.

 "I contemplated starting a master's program for probably five years before I finally took the proverbial plunge," said Petrosky.

As the technology director for the Shanksville-Stonycreek School District (SSSD), a position he has held for the past 13 years, Petrosky said continuing his education was something he wanted to do in order to help his district advance 21st-century learning. But that would mean that he would have to become a 21st-century student — and that was an intimidating thought.

"I had never taken an online class before and I wasn't sure if I could handle it or even what to expect," he said. "I was concerned for a long time about acclimating back to being a student and being comfortable with online learning. That's probably what scared me the most and made me apprehensive.".

In 2015, Petrosky faced his fear and enrolled at Penn State, in the College of Education's educational technology integration graduate certificate program offered through Penn State World Campus. The structure of the program made it easy to transition back to being a student, he said, and his first class — LDT467: Emerging Web Technologies and Learning — was perfect in helping a returning adult student acclimate to online learning...

Now, three years after he took that first class, Petrosky is set to graduate on Dec. 15. In addition to earning his master's of education in learning, design and technology, he also will have received three postbaccalaureate certificates — Educational Technology Integration; e-Learning Design; and Teaching and Learning Online in K-12 Settings (TLOK12). He is the first student at Penn State to complete the TLOK12 certificate program, an approved provider of the state's Online Instruction Endorsement for licensed educators in Pennsylvania.

Word of the Day - Ada Lovelace (Augusta Ada King) | WhatIs.com

Augusta Ada King, Countess of Lovelace, was an English mathematician who is credited with being the first computer programmer. 

Painting of Lovelace seated at a piano, by Henry Phillips (1852). Although in great pain at the time, she agreed to sit for the painting as her father, Lord Byron, had been painted by Phillips' father, Thomas Phillips.

She is known for writing the first algorithm for a machine, inventing the subroutine and recognizing the importance of looping. Countess Lovelace lived from 1815 to 1852. 

Ada, whose given name was Augusta Ada Byron, was the daughter of the poet Lord Byron and Annabella Milbanke Byron, an accomplished mathematician. Ada was educated in music and mathematics by a succession of tutors, including Mary Somerville, a noted mathematician and scientist during the Victorian era. In addition to publishing her own papers, Somerville was known for translating Mécanique Céleste by Pierre-Simon Laplace and adding her own notes to explain the mathematics used by the author.

In 1833, Somerville introduced Ada Byron to Charles Babbage, who demonstrated a working model of a steam-powered calculating machine he called a Difference Engine...

Ada, the programming language created by the United States Department of Defense, is named in honor of the Countess of Lovelace. Since 2009, her contributions to science and engineering have been recognized each year on the middle Tuesday of October.
