Get over the PowerPoint stigma. A screen’s a screen. No one cares if what they see was built in PowerPoint or Flash. All they care about is what it looks like and if it works. Besides, when you build something in PowerPoint and you publish it with your rapid elearning software, it becomes Flash. So instead of using Flash to build a SWF, you’re using PowerPoint to build a SWF.
Think in layers and not linear. People are always asking me about how many slides a course should have. This is the wrong approach when you’re building elearning courses. Don’t think slides. Think content.
