Discovery learning is an
important component of modern constructivist approaches that has a long history
in education innovation. In discovery learning (Bergstrom & O’Brien,
2001; Wilcox, 1993), students are encouraged to learn largely on their own
through active involvement with concepts and principles, and teachers encourage
students to have experiences and conduct experiments that permit them to
discover principles for themselves. Bruner (1966), an advocate of discovery learning,
put it this way: “We teach a subject not to produce little living libraries on
that subject, but rather to get a student to think . . . for himself, to
consider matters as an historian does, to take part in the process of
knowledge-getting. Knowing is a process, not a product”
Discovery learning has
applications in many subjects. For example, some science museums have a series
of cylinders of different sizes and weights, some hollow and some solid.
Students are encouraged to race the cylinders down a ramp. By careful
experimentation the students can discover the underlying principles that determine
the cylinders’ speed. Computer simulations can create environments in which
students can discover scientific principles (DeJong & van Joolingen, 1998).
After-school enrichment programs (Bergstrom & O’Brien, 2001) and innovative
science programs (Singer et al., 2000) are particularly likely to be based on
principles of discovery learning. Discovery learning has several advantages. It
arouses students’ curiosity, motivating them to continue to work until they
find answers. Students also learn independent problem-solving and
critical-thinking skills, because they must analyze and manipulate information.
