The Digital Camera-A Revolutionary Technology.

"Say Cheese!" The art of picture taking (photography) has been a part of our lives for 100's of years. During ancient times, images were created on the wall by passing light through a tiny pinhole (Marples, 2008). History tell us that a photo sensitive compound was created by accident when in 1727 Professor J. Schulze mixed chalk, nitric acid, and silver in a flask and noticed darkening on the side of the flask when it was exposed to sunlight (Greenspun, 2007).

As time progressed, the progression of photo technology evolved to what we now know as the digital camera. According to Dunleavy 2006, it was in the 70's when researchers began exploring the possibility of converting light to create digital images. "Digital camera technology is directly related to and evolved from the same technology that created television images" (Bellis, n.d) Futhermore, Bellis contends that this first digital systems was a Nikon F-3 camera by Kodak in 1986. It was "equipped with a 1.3 megapixel sensor" (today, we are up to 12 megapixels). However, some digital camera timelines show that the first digital camera was the Sony ProMavica MVC-5000 in 1989. Dunleavy 2006 posits that it was not until 1991 when the first professional digital camera system (DCS) was introduced by Kodak (Dunleavy, 2006).

Regardless of when the first digital camera was invented or who introduced it to the market, its development has seen several progressions over time. I would like to introduce a terad that show and how this technology enhances, obsoletes, retrieves, and reverses. It will, therefore, helps us to understand the perspectives behind this emergent technology. Please follow the link below:

The Apple iPod--Biting in Today's Classrooms

In today's classrooms, it's no longer just an apple for the teacher. Many students also have apples-namely, the Apple iPod touch. According to the iPod marketers, its educational apps are not only changing the way students learn but also the way teachers teach. The iPod motivates learners due to its sleek, compact design, its touch sensitive control screen and its similarity to a cell phone that users are accustomed. It contains thousands of applications, including the popular iTunes application.

In my educational setting, we are using the iPod touch as a learning tool. The primary challenge that we are facing with it is having to install a wireless server to accommodate this tool. With this adaptation comes not only the cost of an additional server but also the challenge of maintaining server security.

We are admidst a society that is gadgety. This tool supplies the need of users to have handheld talking, computing or web interfaced devices. If the iPod was also equipped with 3G technonology like the iPad, then sudents could have their own wireless accounts thus eliminate the reliance on the school. However, we would then run into the issue of the "have and the havenots". Examine the following links to learn more about the iPod touch and its educational benefits:
