Introduction
Before computers were commonplace, presenters usually had an easel with posters or
drawings to show any necessary graphics to the audience. In some cases the speaker would
have a slide projector with a carousel of individual slides to show photographs on a screen.
Today, many software package suites contain a program designed to accompany the speaker
when he makes a presentation. The specific presentation program in this suite of programs is
usually (but not always) in the form of a slide show, much like the ones used in years past.
These presentation software programs make it simple and often fun to create a presentation for
your audience. They contain a text editor to add your written content, and abilities within the
program to add charts and graphic images such as photographs, clip art or other objects to
liven up your slide show and get your point across simply.
PowerPoint is an exciting tool that assists in effectively presenting a summation of important
ideas to an audience. PowerPoint can often be intimidating to one who has never used the
program. In reality, PowerPoint can be as simple or involved as the creator’s imagination,
but at its foundation PowerPoint is nothing more than giving life to an outline. In academic
and professional levels a simple and clear PowerPoint presentation is most effective[3]. The
following is a screenshot of a PowerPoint presentation.

Steps to create a PowerPoint presentation:
1.
When you first open PowerPoint, a new presentation will open up. The
default slide design is a white background with black lettering.
2.
To choose a new design background click on format from the toolbar, and
then select slide design. Then simply click on the desired design.
3.
Once you have selected the slide design, click in the placeholders to
add the title and subtitle of the presentation. If the PowerPoint is used to
supplement a paper, then use the title of the paper. If your paper does not
have a subtitle, then you can include the names of those who participated
in the presentation.
4.
To create a new slide, click on the insert tab from the toolbar and then select
new slide. You can also click on the new slide tab located on the right side
of the formatting toolbar.
5.
Continue this process until you have completed your presentation.
6.
If you need to delete a slide select edit from the toolbar and then select
delete slide. You can also move the mouse cursor over the slide you want
to delete in the slide/outline tab. Then right click on the slide, and select
delete slide.
7.
During the creation of the presentation, you can go back and forth between
slides by clicking on the slide you want to view in the slide/outline tab.
8.
To view a slideshow of your presentation, select slide show from the toolbar,
and then select view show. To move between sides, click the mouse
anywhere on the screen.
The above are the basic steps to create a PowerPoint presentation. There are other tools that
can be used such as, inserting pictures, transitions between slides, and music. However, music
and sound effects are not generally acceptable for academic PowerPoint presentations.
Activity Conclusion
PowerPoint is an exciting tool that assists in effectively presenting a summation of important
ideas to an audience. It helps presentations simple and easy to follow while attracting the
attention of the audience. In this learning activity you have been introduced to both basic and
advanced features of PowerPoint presentation tools.
