I came across a cool post about 13 online alternatives to PowerPoint and decided to play with PreZENt it! I made a slideshow and then shared what I learned.
I WISH I could embed the show into this blog post, but it seems that feature isn't enabled.
Just remember, if you're ONLY teaching powerpoint, you're missing it. PowerPoint is great, but it is likely that students will have to change software programs as often as they change their hairstyles over their lifetimes. Fluency is technology is very important as students will have to be able to move from not only job to job but platform to platform.
Get out there and expose your students to more!
