Learning Object-Based E-Learning: Content Design, Methods, and Tools

Colleen is a freelance instructional designer. She recently talked with her client about the possibility of working on an exciting e-Learning development project. However, her client wants her to design it with learning objects, so that they can reuse them in other projects. She has years of experience in designing instruction for classroom training, and developing some online reference materials — but reusable learning objects? She has no experience in developing e-Learning programs with reusable learning objects, and she is not sure where to start. She wants this contract, so she is desperately looking for information. She keeps wondering: Which software should I use? Are there any "recipe" books or articles out there? Help!
