Ten Tech Terms We're Mixing Up

The Internet vs. the Web

The Internet is actually millions of computers interconnected in a global network. (Interconnected +
Network = Internet.) All of these computers can talk to each other to send and receive data around the world as fast as you can favorite a tweet.
The web, on the other hand, is the system where some (but not all) of that data is kept in the form of special documents. These documents are linked together and more commonly known to you and me as web pages. 
To put it simply, the internet is the equipment and connections, and the web is the information. Fun fact: While “world wide web” was the hottest term for the web a few years ago, Millennials prefer to call it “the cloud."

HTML vs. CSS

Speaking of the internet, here’s a bit more about how the websites on it are made. HTML — or HyperText Markup Language — is the language used to write web pages. HTML is made up of “elements” (paragraphs, headers, lists, links, and the like), which give each web page structure and contain the content of the page itself (text, images, videos, and so on).
CSS — or Cascading Style Sheets — tell web browsers how to format and style an HTML document. In other words, CSS is what makes HTML look good. Using CSS, you can give a web page its own font, text styles, colors and, with the newest CSS version (CSS3), even multiple backgrounds, 3D transformations, and awesome animations.
To put it simply, HTML holds the content in place, and CSS makes it look pretty.

Front End vs. Back End

Now you know how websites are made, let’s talk about how they work. The front end of a website is the part that you can see. This includes HTML and CSS and all the other things you look at in your browser. Think Facebook posts that update or Google search terms that autocomplete—these are all thanks to the powers of the front-end programming language JavaScript.
The back end of a website is the part of a website that makes it work. It includes applications that tell websites what to do, servers where websites get data from, and databases where information websites use is stored.
On Twitter, for instance, the look of your feed is the front end, and all the data is stored in the back end.

App vs. Software

Speaking of telling computers what to do, you’ve probably heard the term “application” before. In a nutshell, an application, or app, is a program or set of instructions that you can use to do certain things on your iPhone or Android.
The general term for any instructions for your computer, tablet, or phone is software. So, apps are just one type of software. But, system software—like operating systems (think iOS7 or Windows 8), drivers (controls for your printer or speakers, for example), or utilities (like anti-virus or backup)—are a different type of software that run your computer as a whole and make it possible for you to use all those apps you’re addicted to.
That means: All apps are software but not all software is an app.

UX vs. UI

Even pros can get mixed up about these two abbreviations. UI — or User Interface — is how a product or website is laid out and how you interact with it: Where the buttons are, how big the fonts are, and how menus are organized are all elements of UI.
But UX — or User Experience — is how you feel about using a product or a website. So, your love for the way the new Apple Watch looks or your excitement that there’s finally a tablet-sized iPhone to watch those Corgi videos you’re obsessed with are reflections of UX.
So the new look of the Facebook news feed involves a change to UI, and the way you navigate that new page is the UX.

Hidden Miracles of the Unseen World

We live in a world of unseeable beauty, so subtle and delicate that it is imperceptible to the human eye. To bring this invisible world to light, filmmaker Louie Schwartzberg bends the boundaries of time and space with high-speed cameras, time lapses and microscopes. At TED2014, he shares highlights from his latest project, a 3D film titled "Mysteries of the Unseen World," which slows down, speeds up, and magnifies the astonishing wonders of nature.

Beware the 'digital native' stereotype


found image @ Academia Marketing Digital
Technology teacher Mary Beth Hertz writes on Edutopia that teachers need to beware of the "dangerous" stereotype that all students these days are ‘digital natives’.  There are a lot of dangerous stereotypes out there. "Asian students are always better at math." "Boys are always better at sports." And perhaps the most dangerous of all: "The current generation are all digital natives." Hertz says that just because students know how to use technology doesn't mean they understand how to "create, read critically, use online content responsibly," and be respectful of others in the digital world. And those skills are necessary to be truly digitally savvy, she contends.
Mary Hertz cites a study in which the nonprofit organization One Laptop Per Child left pre-loaded tablets with illiterate children in remote Ethiopian villages. The children quickly figured out how to use the applications and began teaching themselves to read. Within a few months they'd overridden the software meant to freeze the desktop settings, and customized their devices.  But Hertz says this proves her point that being able to use technology does not make you proficient:
“Sure, we can place a tablet in the hands of children who have never seen a package label or a sign, and they will learn on their own. But what happens when and if those children become connected to the larger, global online community? It is not guaranteed that they will be ready to navigate etiquette and intellectual property rights on their own. “
Instead, Hertz writes, we should call students "digital citizens," which implies a more complicated relationship with technology—not innate proficiency.
She is not the first to argue that teachers cannot assume students know how to properly navigate the digital world. Jody Passanisi and Shara Peters said in Scientific American that students struggle with basic Internet searches, and a majority of teachers in a recent Pew Research Center survey said students need more training in finding credible information online.
Perhaps Hertz' claim boils down to semantics. Aren't 'digital natives' simply those who've only known a world in which electronic devices are the primary means of accessing information? The term brings to mind this video.

Blogs as a teaching tool


As the Internet becomes an increasingly pervasive and persistent influence in people's lives, the phenomenon of the blog stands out as a fine example of the way in which the Web enables individual participation in the marketplace of ideas.

Teachers have picked up on the creative use of this Internet technology and put the blog to work in the classroom. Even though newer and more appealing Web 2.0 technologies are on the move, education blogs can still be a powerful and effective tool for students and teachers alike.



What is a blog?
A blog (sometimes referred to as a weblog) is a Web publishing tool that allows authors to quickly and easily self-publish text, artwork, links to other blogs or Web sites, and a whole array of other content.
Blogs are set-up like conventional Web sites, with navigation links, and other standard Web site features. Blogs have one standard characteristic, however: the posting. Blog postings are text entries, similar to a diary or journal, which include a posting date and may include comments by people other than the author, photos, links, or other digital media.
Postings are often short and frequently updated. They appear in reverse chronological order and can include archived entries.
Blogs work well for students because they can be worked on at virtually any time, in any place with an Internet-enabled computer. Hence, they can be used to create a classroom that extends beyond the boundaries of the school yard.


User-Friendly Technology
Blogs are surprisingly easy to use. They require minimum technical knowledge and are quickly and easily created and maintained. Unlike many traditional Web sites, they are flexible in design and can be changed relatively easily. Best of all, students will find them convenient and accessible via home or library computers.

Educational Benefits of Blogs
In addition to providing teachers with an excellent tool for communicating with students, there are numerous educational benefits of blogs. Blogs are:
  • Highly motivating to students, especially those who otherwise might not become participant in the classroom;
  • Excellent opportunities for students to read and write;
  • Effective forums for collaboration and discussion;
  • Powerful tools to enable scaffolded learning or mentoring to occur.
Using the Blog in the Classroom
As an educational tool, blogs may be integrated in a multi-faceted manner to accommodate all learners. Blogs can serve at least four basic functions.
  1. Classroom Management (blogs may serve as a portal to foster a community of learners; they can be used to inform students of class requirements, post handouts, notices, and homework assignments, or act as a question and answer board);

  2. Collaboration (blogs provide a space where teachers and students can work to further develop writing or other skills with the advantage of an instant audience. Teachers can offer instructional tips, and students can practice and benefit from peer review. They also make online mentoring possible);

  3. Discussions (a class blog opens the opportunity for students to discuss topics outside of the classroom. With a blog, every person has an equal opportunity to share their thoughts and opinions. Students have time to be reactive to one another and reflective);

  4. Student Portfolios (blogs present, organize, and protect student work as digital portfolios. As older entries are archived, developing skills and progress may be analyzed more conveniently. Additionally, as students realize their efforts will be published, they are typically more motivated to produce better writing).

Safety issues

Take the necessary steps to secure parental permission before using the blog in a participatory manner.
Blogs may be viewed publicly, as any other Web site. Students must be trained on issues regarding access, privacy, security, and free expression. As blogs have no publisher, producer, or editor, students must carefully consider the content of postings to avoid anything defamatory, libelous, or an infringement upon the rights of others.
