Learning objects are online resources that can be:
- Reduced to smaller, manageable chunks that can be tagged and shared for later use (Kopi explains that by classifying learning objects into 5 types, there is better understanding and ability for retrieval.)
- Reused by others for a variety of purposes
- Recycled in new ways, allowing for integration in multiple areas
Advantages
I understand the benefits of learning objects in regard to cost effectiveness by being able to reuse content & not having to “recreate the wheel”, being able to tailor a program by using smaller applicable “chunks”, and the potential ease of tagging and sharing online. Merrill writes that the use of “learning objects increases the precision with which instructional strategies can be described.” Many recognize the benefit of embedding learning objects into web-based instruction models. Bannan-Ritland, Dabbagh, and Murphy describe the learning object systems as providing “yet another technology-based instructional delivery environment with exciting features and attributes that can empower learner-driven experiences…”
At this point, there are many disadvantages associated with learning objects (and the means of housing and sharing them). Because of the economy types, there may not be easy access to the best materials and/or the credibility of content might not be secured. As with a wiki, users should be aware that just because content is available, it does not mean that the information is accurate. Another downside is the contextual component. When the context is removed to break the learning objects into easily tagged bits, it can be challenging to then reframe the objects for use. Wiley also brings up an interesting point in his article. He feels strongly that learning objects are merely “content chunks” or “information containers” that limit a learners ability to execute higher level thinking. He reflects, “They are utilized as glitzy information dumps, or lectures with high production values, as if all that online or distributed learning required was a larger megaphone for the instructor.”
As new ways to develop, shape, store, and share learning objects evolve, there is potential for them to be very effective components of web-based instruction. I am reminded of the quote that "Rome wasn't built in a day" and recognize that it will take time for the sharing structure to be refined.
I started with a song reference, so it only seems fitting to end with one. As few lines from an Ed Cash song remind us:
But he knew he still had work to do
Because he remembered that
Great things take time
Because he remembered that
Great things take time
Nice post, Julie. I liked the song references! They are appropriate and give a good definition of learning objects. You make a valid point about wiki content possibly being inaccurate. Koppi's article mentions quality control and the U21 project and difficulty in defining quality. I suppose it would be up to the instructor to comb resources, do some research, and select the right ones for his or her courses.
ReplyDeleteI sing that song with my kids when we talk about recycling...now I've got another thing to think about with it! I think that's the best part of using learning objects- getting to reuse and recycle others' ideas and reducing the time you spend "reinventing the wheel."
ReplyDeleteGreat post! Learning objects can be reused and can benefit educators by allowing them to choose the appropriate content for the class. Teachers can also use the wiki's as an example of what online research tools students shouldn't use.
