We’ve come a long way from the first cell phones. The
concept isn’t a new one; in fact in 1947 Douglas H.
Ring & W. Rae Young, Bell Labs engineers, proposed
hexagonal cells for mobile phones.

The real launch of the first portable phones was in
the primeval 80’s. At that time only the  wealthy or
“well to do” individuals had them.

As huge as they were though, they didn’t have a clear
sound & using them was a hassle. At first, all were
designed for permanent installation in vehicles
otherwise known as a “car phone”.

they were  massive & heavy. Not something to be
carried in your pant pocket or purse, this was
something that weighed a few pounds.

The first digital cellular phone call was prefabricated in the
United Says in 1990. they shrank considerably.

a quantity of these bulky units were soon converted for use
as “transportable” phones the size of a briefcase.
Motorola introduced the first truly portable, handheld
phone.

Cell phones used to be  analog phones, with the
sole purpose of providing the consumer with the
capability of making & receiving voice calls while
on the road.

As technology has advanced so have the capabilities of
the mobile phone. they don’t  send & receive calls
now; they are capable of text messaging, emailing,
taking photos & video clips.

As they continue to advance, so will the capabilities of
cell phones. In the next few years, cell phone
networks will move data at several megabits per
second, & will coexist with WiMax, Wi-Fi, &, for
TV, DVB-H or MediaFLO.

The sizes have gotten smaller yet their capabilities have
improved.

The classroom environment this day is absolutely different from the traditional classroom we’re all used to years ago. The introduction of new technologies, such as document cameras, interactive whiteboards and classroom response systems, have added not only excitement but student engagement and true interactivity within the classroom.

Technologies are consistently changing and improving. Overhead projectors are still being used, however, they have been replaced by document cameras. The capability to project a book or document on the fly grants instructors the freedom to adjust their lesson to the direction of the discussion.

Whiteboards have replaced chalkboards, interactive whiteboards have replaced regular whiteboards, and now interactive whiteboard technology is replacing conventional interactive whiteboards such as Smart and Promethian. This new interactive technology grants schools to keep their existing whiteboard and add a device which will turn their whiteboard into an interactive whiteboard. No more installing interactive whiteboards on top of the school’s original whiteboard! Educational technology  has granted schools to save money and improve their current setup. Also, this new interactive whiteboard technology grants capture. Capturing physical ink from the whiteboard WITHOUT the use of the projector!

Teacher’s now have websites and post their notes and future assignments. The new interactive whiteboard technology, i. e. mimio, grants for regular ink capture and instant uploading to the Internet.  

Another educational technology recently introduced to the classroom are classroom response systems or voting systems, also know as “clickers”. There are many different manufactures: LearnStar, Renaissance, InterWrite, and Scantron are just a few. Each student would have a clicker or handheld device. There are typically two kinds. The small one has only numbers and the massive one has both numbers and a full keyboard. A full keyboard grants students to answer multiple choice as well as fill in the blank questions. The most common use are “polling” type questions. There is a software program specific for clickers, A+Classroom, which has a patented competition mode. Students receive points based on the speed in which they answer the questions. Students are constantly asking for more questions during this mode. Students that typically don’t raise their hand or voluntarily involved in the class are now engaged and competing with the other students. Since there is an option to keep the obloquy confidential, only the students know where they are ranking within the class.
