Visiting a library may not seem fun or interesting, but the ones below might be the most beautiful and attractive around the globe.

Widener Library, Massachusetts, the United States

As Harvard’s flagship library, the Widener Library was built in 1912. The library was named after Harry Elkins Widener, a 1907 Harvard graduate who donated 3, 300 books, invaluable paintings and money. The length of shelves reaches 91 kilometers. Today, it is known as a “silent library”, with two floors of quiet study rooms and five floors of underground literary resources.

Biblioteca Joanina, Coimbra, Portugal

The Biblioteca Joanina was named after its founder, King John V of Portugal, who started building the library in 1717. The library, located at the University of Coimbra, houses 300, 000 book collections. Many of the books were printed before the 1800s. The library is a huge tourist draw because of its decorative dark-wood arches and shelves.

Trinity College Old Library, Dublin, Ireland

Located in the center of Dublin, the Trinity College Old Library was constructed in 1712. With its two stories of dark-wood arches, the library is not only one of the world’s oldest libraries, but one of the most famous ones. The Long Room in the library is 65 meters long, filled with 200, 000 books and sculptures of great writers associated with the college.

Tianjin Binhai Library, Tianjin, China

Unlike the other libraries on our list, this one is practically new. As a cultural landmark of Tianjin, the Binhai Library officially opened to the public in 2017. Its breathtaking design was described by Time magazine as a “ziggurat” and has received a lot of attention from the public. The 33, 700 square-meter building can hold 1. 35 million books. Built in just five years, it has become a tourist attraction since it was finished.

Do students learn as much when they read digitally as they do in print? Investigators have been trying to determine whether students do as well when reading an assigned text on a digital screen as on paper.

A number of researchers have sought to measure learning by asking people to read a passage of text, either in print or on a digital device, and then testing for comprehension.

Most studies have found that participants scored about the same when reading in each medium, though a few have indicated that students performed better on tests when they read in print.

Since in standardized testing, reading passages and answering questions afterwards may tell us little about any deeper level of understanding, some researchers are beginning to pose more subtle questions.

When people were asked to read d story in print or on a digital device and then to reconstruct the plot development, the answer is: Print yielded better results. When people were asked to read by choosing how much time to spend on each platform, the researchers found that participants devoted less time to reading the passage on screen and performed less well on the following comprehension test.

So, how does the learning question relate to educational goals?

To become skilled in critical thinking, students need to be able to handle text. The text may be long, complex or both. To make sense of it, students cannot skim, rush ahead or continually get distracted. So, does reading in print versus on screen build critical thinking skills?

When asked in which medium they felt they concentrated better, 92 percent replied “print”. For long academic reading, 86 percent favored print Participants were also reported to be more likely to reread academic materials if they were in print

What’s more, a number of students indicated they believed print was a better medium for learning. By contrast, in talking about digital screens, students noted “danger of distraction” and “no concentration”.

Evidently, it’s not too hard to tell that a pattern did emerge: Print stood out as the medium for doing serious work.

Mistakes that Worked,written by Charlotte Foltz Jones,award-winning author of non-fiction books for children, offers forty of these unusual tales,along with many interesting drawings and strange and amazing facts.

The book is divided into six parts: food,medicine,toys,accidental things,names,and I find the book great because if not for the book,I would never have known that something was actually accidentally created.Besides,I like to learn real information;I can't stand books with stories that aren't real.Although this is a non-fiction book and is about inventions,it is not a history of technology book;it's more of an easy reading book.This book would be attractive to both boys and girls,and it could actually be either an adult book or a children’s book.

Published in 1991,the book is a bit old and is showing its age now in 2016.Still,it contains lots of great information,even though some facts are not exact.I love the idea of a mistakes book,and I especially like the format, which allows readers to dip in and out of the book easily.However,the entries are not all equally strong. Additionally, if you don’t live in the US,the book makes little sense,since it is full of American references both historically and in terms of customs.

Anyway,Mistakes that Worked is a reminder that failure is not always the end.It is an enlightening book that encourages us to realize that taking risks and learning to experiment is often the best way to learn,even if we don’t end up creating something new and wonderful.
