Computers and Technology in the Academic Learning of Young Children

In today’s world, computers have become a familiar fixture in the daily lives of children and adolescents, offering a wide range of learning and entertainment tools.

While surveys have indicated that boys are heavier users of computer games and visit websites more often than girls, no gender differences have emerged for chatting, using e-mail, or doing schoolwork on the computer. Additionally, both teenage boys and girls have expressed equal confidence in their computer skills.

On average, parents estimate that their school-age children and adolescents use the computer approximately 1.5 hours per day. Computers, electronic games and toys, and technology in general largely influence and affect the lives of children. Technology has thus proven to be largely capable of enriching the lives of children, especially in the areas of academic and social learning and development.

Computers for instance, can have rich cognitive and social benefits. Children as young as 3 years of age like computer activities and are capable of typing in simple commands on a standard keyboard. Additionally, in today’s classrooms, small groups often gather around the machine, and children more often collaborate while working with the computer instead of using traditional paper and pencil methods.

As soon as children start to become literate (being able to read and write), they can make use of the computer for word processing. This lets them write without struggling with handwriting, and they can revise text meanings and style, and check their spelling. As a result, children tend to worry less about making mistakes, and their written products end up longer and of higher quality.

Specially designed computer languages introduce children to programming skills. With the support of adults, children’s efforts with computer programming can lead to improved concept formation, problem solving and creativity. Furthermore, as children must detect errors in their programs to make them work, programming will assist them in reflecting on their though processes. This will inevitably lead to gains in meta-cognitive knowledge and self-regulation. Also, while programming, children are particularly likely to collaborate, persist in the face of challenge, and demonstrate positive attitudes toward learning. This is consistent with Vygotsky’s theory in showing that social interaction supporting children’s mastery of challenging computer tasks is capable of fostering a wide range of higher cognitive processes.

Children and adolescents spend much time using home computers purely for entertainment purposes. Many computer games emphasize speed and action in sometimes violent plots where children advance by shooting at and evading enemies. Children additionally play more complex exploratory and adventure games with themes of conquest and aggression and sports games. These include football and soccer. Children likewise enjoy simulation games, for example creating and caring for virtual pets (which require attention to “stay alive”), entering virtual realities (such as an ecosystem where the player mutates plants and animals into new species), and role-playing characters.

Speed-and-action computer games cultivate attentional and spatial skills in both boys and girls. However, while offering opportunities for learning, extensive playing of simulation games might risk blurring the distinction between virtual and real life.

Many youths use the computer to communicate. While using the internet causes some potential for causing disengagement from real life, it does hold much value in letting users acquire computer skills, information, and enabling communication.

Using the Root User for Linux System Administration – Linux Training Online – Linux Concepts & Terms

There are often several Linux OS (operating system) terms that are similar, the same, or somehow related.

This article will clear up the confusion about the terms: root user, / (root directory) and /root (the home directory of the root user)!

First, you will learn about the root user, and then see a brief description of the / (root) directory and the /root (home directory) of the root user.

Linux Tips: The articles with names ending in “Linux Concepts & Terms” help you learn Linux “geek-speak” (terms). By learning Linux terms (the Linux “lingo”) you will be able to understand Linux concepts and more easily learn how to use Linux. This is an excellent way to start your Linux training.

The root User

To do Linux system administration tasks, like create Linux users and assign permissions to users, you work as the Linux user named root.

The root user has all permissions (rights, capabilities) to all of the Linux system, including all directories and files.

Linux users that are used for day-to-day tasks, like word processing and working on a spreadsheet, are referred to as “regular” or non-root users. When you’re not doing Linux system administration tasks, always work as a non-root user.

When doing Linux system administration, work as the root user and be extremely careful running Linux commands – because you could damage or destroy your Linux installation – and then immediately log out!

The root user is also referred to as superuser (no, really, and you don’t even get a cape!) and also referred to as su.

When you boot Linux to a console or terminal (and not a Linux desktop), you see a text (not GUI) Login: prompt and you can log in as root to do Linux administration tasks.

However, when you boot a Linux system that has a desktop, you log in at a GUI login prompt and then the Linux desktop appears.

For various security reasons, never log in to a Linux desktop as the root user. Log in to the Linux desktop as a “regular” (non-root) user and then open a Linux terminal (terminal emulation window) on the desktop and use the su command with the – (dash) option to log in and work as the root user.

Linux Tips: The Linux su command gets its name from the word superuser. The su command is run in a Linux terminal emulation window to log in and work as the root user, after logging in to a Linux desktop as a “regular” (non-root) user. Never log in to a Linux desktop as the root user.

Linux Tips: By default, the root user is locked (disabled, unusable) in Ubuntu Linux and you run the Linux sudo command along with Linux system administration commands rather than logging in as root – or using the su command to log in as root.

Now, imagine how easy it will be to learn how to use Linux by seeing all these Linux terms and concepts being clearly presented in a Linux video tutorial!

Related Linux Terms Below are the terms that are similar to, and related to, the root user.

Similar Linux Terms: root user, / (root) directory in the Linux file system and /root (the home directory of the root user)

The / (root) Directory The root directory of the Linux filesystem is represented (symbolized) by a / (forward slash). All directories in the Linux file system are “below”, or “off of” the / (root) directory.

The /root Directory – The Home directory of the root User The directory named root, located directly “below” or “off of” the / (root) directory, is the “home” directory of the root user.

Linux Training – Linux Installation Help – Linux Live CDs & Linux Installation CDs – Pros and Cons

You get real, practical Linux training when you get Linux running on a computer system, and you work with it to get experience.

Once you get the Linux OS (operating system) running, you can learn how to use Linux desktops, run Linux software programs, and most importantly, go to the Linux command line to run Linux commands – the real power behind Linux system administration.

Two popular methods of getting to work with the Linux OS are:

1. Install Linux from CD or DVD onto the hard disk in a system

2. Boot and run Linux from Linux live CDs or DVDs (without installing Linux)

Here are some of the pros and cons of installing Linux on a system and running Linux from a live CD or DVD.

Linux Live CDs – Pros

1. The Linux OS boots and runs in just a few minutes entirely from a single Linux live CD (or DVD).

2. A lengthy Linux installation is not required. You don’t need to provide a lot of settings to the Linux installation routine and then wait while the Linux OS and Linux software programs are copied onto the hard disk.

Also, if you install Linux on Windows, you need to back up your system before you do and you may damage your Windows setup during the Linux installation – or if you remove Linux later!

3. You only need to get 1 Linux live CD or DVD, as opposed to possibly needing several when you install Linux. Therefore, if you download Linux to burn a Linux ISO file to CD / DVD, you only need to wait while 1 Linux CD / DVD is downloaded.

4. Linux live CDs / DVDs are very inexpensive. If you don’t want to download Linux as a live CD / DVD, you can order one and have it mailed to any location on the planet for a very small amount of money. Just run your browser and do a search for “list of linux cds” or “list of linux dvds”.

Linux Tips: If you are going to buy a Linux live version and you have a DVD drive, get a Linux live DVD rather than a CD. A DVD holds about six times as much as a CD. Therefore, you’ll get lots (and lots) more Linux software programs on a DVD!

5. A Linux live CD can easily be removed and taken anywhere. Portable Linux!

6. You can save your work (data files) – if you get the right Linux live CD or DVD.

Linux Tips: Before getting a Linux live CD / DVD, do some research to make sure you can save your work. Some Linux live distros let you save your data and some don’t. For example, the Ubuntu Linux live CD allows you to save your work to a USB flash drive.

Linux Live CDs – Cons

1. Although booting from a Linux live CD / DVD is faster than doing a complete Linux installation, you still need to wait while your system boots from the live CD / DVD, every time your system starts. If you usually keep your system turned on, this isn’t an issue.

2. You may not be able to save your work. Some Linux live CD / DVD distros allow you to save your work and some don’t.

3. You need to boot from the Linux live CD / DVD every time your system starts. This may not be very convenient if you need to put other CDs or DVDs in the drive while running Linux “live”. Any time you need to put something in your drive, you have to remove the live CD / DVD. This also increases the likelihood that your live CD or DVD will become damaged.

Linux Tips: Keep a copy of your current Linux live CD handy in case your working copy becomes damaged.

Either way, installing Linux or using Linux live CDs (or Linux live DVDs), is an excellent way to get Linux training so you can learn how to use Linux.
