Query: Problem Solving and Learning   One finding of cognitive research is that people do not automatically acquire
usable knowledge by spending lots of time on task. Because students' knowledge
hierarchy is more fragmented, "knowledge chunks" are smaller than those of
experts. The limited capacity of short term memory makes the cognitive load
high during problem solving tasks, leaving few cognitive resources available
for metacognition. The abstract nature of the laws of physics and the chain of
reasoning required to draw meaningful inferences makes these issues critical.
In order to help students, it is crucial to consider the difficulty of a
problem from the perspective of students. We are developing and evaluating
interactive problem-solving tutorials to help students in the introductory
physics courses learn effective problem-solving strategies while solidifying
physics concepts. The self-paced tutorials can provide guidance and support for
a variety of problem solving techniques, and opportunity for knowledge and
skill acquisition.
