How to match a learning object to the lesson objective

I'm glad you're asking this. If there were a clear, unambiguous way, there wouldn't be so many learners dissatisfied with the courses they take, right?

The best way to know whether the objects you chose are the right ones is to have a well-defined learning objective. Once you're clear on it, it becomes much more obvious how to prove that your learner actually learned. From there, you can use multiple learning objects to get there. There is no step-by-step recipe for this last part: it depends on your company's or school's methodology and pedagogical approach. In the next module, when we present some learning objects, we'll explain when each one is most useful. Still, use and abuse your creativity. And always ask your learners for feedback. They are the best people to give you complete feedback.
