impact of ICT on education

COMPUTER BASED LEARNING 

What is computer based learning?

*Computer-based learning is a term that can be used to describe virtually any kind of learning program using computers as a central staple. This approach to learning takes advantage of the interactive elements of computer software, along with the computer’s ability to present many different kinds of media. There are several potential advantages of computer-based learning programs, including the ability for people to learn from their homes and study without the assistance of an instructor.



What are the uses of computer based learning?

• Learning involves the active construction of
knowledge through the process of inquiry, thinking,
problem solving, creating and communicating.

• Learning is purposeful. It derives from a desire to
make sense of the world and act upon it.

• Learning is based on previous knowledge and
requires challenges to the initial conceptions which
students bring from their home and other familiar
environments. The challenges lead to new insights
which require students to reorganise or extend
their existing framework of knowledge.

• Learning is interactive. It is more effective when
students are engaged in interaction with the
teacher, other students and resources, including
technology.

• Learning occurs in a context of use, i.e. the
situational and interactional circumstances in
which knowledge is constructed and used.

• Learning is most effective when conceptual
content is interrelated. It involves making
connections and forming knowledge structures.

Online system

Define the following:
 
E-banking:

e-Banking delivers real-time information to you about your accounts. All you need is a personal computer with Internet access, and you’ll be able to:
  • Check account balances.
  • View account activity.
  • View and print images of checks and deposits.
  • View and print statements.
  • Transfer funds between accounts.
  • Place Stop Payment order on a check you have issued.
  • View existing Stop Payment orders.
  • Make CNB loan payments.
  • Make any of your transfers or payments a one-time event or a recurring event on the schedule you choose.
  • Download account transactions to your software application, such as Microsoft Money or QuickBooks.

Online transaction:

An online transaction, also known as a PIN-debit transaction, is a password-protected payment method that authorizes a transfer of funds over an electronic funds transfer (EFT)

How it works/Example:

When you pay for goods or services with your debit card, you have an option for the payment to be processed in two different ways: as an offline transaction via a credit card processing network, or as an online transaction via an EFT system, requiring a personal identification number (PIN) to complete the process.
When processed as an online transaction, the exchange of funds is completed using an EFT network, such as Star, Pulse or Interlink, depending on which EFT system your bank is associated with as a member bank. The cost of the transaction typically amounts to an interchange fee of 1% of the total purchase price, which is charged to the vendor/merchant.



E-shopping:

The act of purchasing products or services over the Internet. Online shopping has grown in popularity over the years, mainly because people find it convenient and easy to bargain shop from the comfort of their home or office. One of the most enticing factor about online shopping, particularly during a holiday season, is it alleviates the need to wait in long lines or search from store to store for a particular item.


Online auction:

An online auction is an auction which is held over the internet. Online auctions come in many different formats, but most popularly they are ascending English auctions, descending Dutch auctions, first-price sealed-bid, Vickrey auctions, or sometimes even a combination of multiple auctions, taking elements of one and forging them with another

Advantages: 
1) Merchandise has exposure to the traffic of the online auction site. 
2) If an item is popular, bidders can push the price up beyond its starting price. 
3) If you are selling more than one item on the site, you can add a link for 
visitors to view the other items for sale. 
4) You can add multiple photos with different views. 
5) You can add detailed decriptions and shipping information. 
6) Some sites offer promotions with no listing fees or other specials for a 
limited time. 
7) The ability for potential customers to review feedback left from buyers or 
sellers. 



Disadvantages
1) The item may not sell, you'll have to re-list it, and pay an additional fee. 
2) A buyer may bid and not pay, resulting in a lost sale and a re-listing fee. 
3) It is time-consuming to add a category, descriptions, price, shipping 
method, and photos to a listing. 
4) It is time-consuming to promote listings to drive traffic to auctions.
5) People may try to convince you to close a listing and sell to them off the site
