Learning Object Technologies
With the advent of technologies for storing, labeling, sorting, and delivering educational content dynamically, many instructors have begun to rethink what constitutes traditional units of instruction. Instead of the one-day lecture, multi-day module, or term-long course, some instructors are focusing on smaller units of learning, such as digital content modules, activities, and student performances that can stand alone as self-contained, reusable objects and be gathered together and organized differently by any number of instructors. These instructors often share objects by storing them along with descriptive metadata in repositories such as Merlot.
Seminar

12:00 p.m.-1:30 p.m.
274 McNeal Hall
Moderator:
Scott Wilson-Barnard
Digital Media Center, Office of Information Technology
Panelists:
Jenni Swenson
Department of Soil, Water, and Climate, College of Agricultural, Food, and Environmental Sciences
Simon Hooper and Charlie Miller
Department of Instructional Systems and Technology, College of Education and Human Development
Victoria Mikelonis and Lenna Constantinides
Department of Rhetoric, College of Agricultural, Food, and Environmental Sciences

At the seminar, we asked the panelists to consider questions such as the following.
- What is a learning object? What process do instructors use to repurpose existing materials as collections of objects or to design new objects?
- Are there pedagogical and technical advantages to pursuing an object-oriented design strategy?
- What is metadata? Are there existing metadata standards? What is the process of gathering metadata? Are there related pedagogical advantages?

Questions and Comments
About 40 people, including the moderator and panelists, attended the seminar.
Moderator's Comments
Moderator Scott Wilson-Barnard began by defining learning objects (see the Academic ADL Co-Lab (AADL), the University of Wisconsin System (UWS), and Wisconsin Technical College System (WTCS) page, "What Are Learning Objects?" for details). They are small chunks of instructional content that are
- discrete/self-standing,
- re-usable, and
- associated with descriptive metadata.
The seminar participants asked questions and discussed topics such as the following.
Questions for Swenson
Why are you including metadata?
Swenson explained that "doing metadata is harder but it will make a much better product." She and Rehm decided to use the Dublin Core Metadata Initiative standards because the educational descriptors "enable creators to describe factors specific to the intended audience (students, farmers, researchers, etc.), instructional level," and the like.
How are you controlling quality?
Faculty members who wish to contribute content contact Rehm and Swenson, then Swenson interviews them and converts the materials to digital and the e-Soils formats. She then works with the department head to determine how to present the most relevant information the most effectively, then reworks the material accordingly.
Could quality control be set up like on Amazon.com so that users rate the objects?
There is a student feedback function, but substantive rating is still all manual and internal.

To complement Littlejohn's book (Littlejohn, Allison, ed. 2003. Reusing Online Resources: A Sustainable Approach to E-Learning. London: Kogan Page), this special issue was devoted entirely to the challenges and opportunities posed by the design, development, and use of educational objects. Of particular interest are chapters and editorial commentaries on the challenge of atomizing course materials and learning activities (responding to the book's "Chapter 2: Granularisation"); ensuring that the recombination of educational objects in new course settings is pedagogically sound (responding to the book's "Chapter 3: Keeping the Learning in Learning Objects" and "Chapter 5: Combining Re-usable Learning Resources"); and considerations for designing and assessing the effectiveness of learning objects (for example, responding to the book's "Chapter 9: Designing for Reuse and Versioning" and "Chapter 14: Assessing Question Banks").
