A number of design guidelines for the development of multimedia
instructional materials have been developed under the assumption that learners have two
modal processing channels, and that learning is better when people utilize both of these
channels to store and process information (Mayer, 2001). The present research extends this
approach by differentiating between internal and external effects of modality. The goal
of this extension is to avoid the resemblance fallacy: the false assumption that internal
representations have the same characteristics as external representations (Sacife & Rogers,
1996). An experiment demonstrates that this extension can better explain learning from
multimedia. This knowledge helps provide more precise guidelines for the design of multimedia
instructional materials.

Many procedural tasks that people need to do are unfamiliar or seldom
encountered, in which case instructions are needed to help perform the task. Given that
instructions are available, how do people make use of them? It is often assumed that
instructions should be read before attempting a task, but people often do not use the
instructions until they do not know (or cannot guess) what to do next. Which method is
more beneficial to performing a procedure: reading the instructions before doing the
task (instruction-based strategy) or using them as a reference (task-based strategy)?
I have attempted to answer that question in an ongoing research project that compares
the effect of these different strategies on one-time procedural performance, procedural
learning, and transfer of procedural learning.

In the traditional model of education, students are typically not involved
in the production of knowledge; they read what others have written for
them and they listen to what more knowledgeable teachers have to say. It
has been observed by educational researchers that resources like textbooks
often conceal from students the disciplinary practices, passion and effort
that authors invest in producing texts. Open content production and wikis
in particular provide an unprecedented opportunity to involve students in
the intellectual work of the world. Science Online is a new project at
Georgia Tech that explores the power of open content development as a
learning activity using wiki tools.
