Unformatted text preview: stem. I use a computer simulation that keeps track of how
changes in the four variables affect different species. My students can
concentrate on interpreting what is happening rather than focusing on
record keeping and graphing. John Saraguso’s application of technology is similar to allowing math
students to use calculators during complicated problem solving activities. In both
cases, students can concentrate on the mental processes involved in problem
solving rather than on calculations or record-keeping. These types of applications
can improve students’ performance by offloading some task requirements to the
technology, and by supplementing the capabilities of working memory (Baylor,
2000; Kumar & Wilson, 1997; Lembrecht, 1993).
Working memory load can also be managed by helping students develop
behavioral fluency for certain simple skills like math calculations. Students have
achieved behavioral fluency when they can perform a skill quickly and with
minimal or no errors (Spence & Hively, 1993). As you may remember from 41 Chapter 3, informati...
