Emerging Technologies Tetrad

Module #2 Assignment: Transistor

Enhances: It is a semi-conductor that is used to amplify and switch electronic signals and electric power. Key component to all electronics.

Obsoletes: vacuum "electron" tube

Retrieves/Rekindles:  Has the ability to use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals. A transistor can control its output in proportion to the input signal; that is, it can act as an amplifier.

Reverses:  vacuum tubes that have an improved electron mobility and can function at a higher voltage.

Identify an Emerged Technology

Since I work in the field of education, we have a wide variety of technology at our finger tips. A current technology that has emerged in the last few years that shapes learning or productivity in education is CPS Units (Classroom Response System).

There have been a lot of problems associated with the CPS units. For example, when we first received the units to try in our classrooms, the remotes would change modes at random. This would cause a huge problem especially when we had a multiple choice test or quiz. When the mode would change it would only allow the student to insert numbers which would in turn cause the student to enter the wrong answer. Also, the program on the computer would not receive answers is the remotes were not set to off before the lesson was engaged. At the time we had no idea about this little problem.

The benefits of using the remotes allows teachers to save time since they do not have to hand grade quizzes and tests anymore that are multiple choice. I know that there are scantrons, but the CPS program will give instant feedback of who missed what question. Teachers are able to pull question analysis reports so that they can remediate students immediatly on questions that they struggle with.

Some of the ways that CPS remotes could be improved is by fixing the small problems associated with the remotes. Having the remotes where they do not change modes is one way that they can be improved. Teachers struggle with technology in the classroom especially if all the remotes change modes at one time. Sometimes having a back up plan is more complicated than the original plan.
