ICT practices in science lessons using power point

I believe that most Science teachers nowadays like to carry laptop or Ipad to deliver their lesson by using power point if the laboratory has access to projector. 

Recycled Presentations
The greatest advantage of using PowerPoint for classroom lessons is that you can modify them and use them over and over again, each time you teach those lessons.

The advantages of using a Powerpoint presentation:

• A Power Point presentation could get and enhance the attention and interest of the intended audience because people would traditionally pay attention to presentations or shows that use visuals especially dynamic images, animation and other visuals that could move or be maneuvered by the presenter.

• Learning to use a Power Point presentation does not necessarily involve a formal lesson because an individual could easily learn and teach himself in using Power Point because its tools are user-friendly and easy to follow with the various tips and sample templates offered by the program.

• Power Point could be used as an effective tool for illustrating images and visuals that are difficult to draw with the use of traditional drawing tools such as pencils and pens compared to the graphics applications that could be used in Power Point.

The disadvantages of using a Power Point presentation:

• A Power Point presentation that uses too many animations, graphics, background images and other dynamic visuals could distract the audience from the actual message and other information being conveyed to them.

• Power Point is not suitable in using for some types of presentations such as commencement speeches, poetry recitations, and technical reports that require detailed processes or procedures.

• A Powerpoint requires a set of system requirements. A presentation for a medium to large size audience would need an interrupted source of electricity during the presentation, a computer system that is free from technical problems and software breakdowns, a projector, speaker system, and other system requirements for carrying a successful presentation.
