Research and write out your case study before you attempt putting it into a PowerPoint format. This will help you stay organized and focused. Since you'll be reducing the word count and simplifying sentences when you make your PowerPoint slides, it will be helpful to have a good amount of information already written out to choose from.
Save two copies of your case study in separate Microsoft Word documents--one for simplifying into PowerPoint format, and one to keep as the original. You may want to supplement your presentation with a handout of the full text of your case study.
Open the copy designated for simplifying. Read through the information that you have gathered in your case study and remove anything that could be considered unimportant or trivial. Remember that PowerPoint presentations are meant to be concise.
Separate your case study into different sections and give each one a heading. If you have already written the case study, this should be very easy, since its usual format includes specific sections.
Simplify the information in each section into bullet points, using short sentences and phrases. Avoid including long sentences or paragraphs in your bullet points--stick to key facts and cut back on words.
Open the PowerPoint program and create your title slide. Then, add another slide and create a heading at the top in accordance with the first heading in your case study. Type or copy and paste the bullet points from the Word document onto the slide. You may need to make several slides with the same heading if you have lots of information pertaining to it. Continue making slides for each heading until all the information is in your PowerPoint.
Remember to end your presentation with a slide listing any sources you used in APA format.
Make sure you choose fonts, text sizes, and colors that go well together and are readable from a distance.
