Learning objects

Learning objects (LO) are short, self-contained, reusable teaching materials found on the Internet. These can be used to illustrate, support, supplement or assess student learning. They are small in size, and can take on a variety of different shapes, formats, and purposes. The following LOs are developed by UPD faculty and are available at the DILC website:
