Investigates a complex aptitude treatment interaction (ATI) of intelligence and metacognitive skill as aptitudes with structuredness of learning environment as treatment, based on a study of undergraduates in simulation environments. Highlights include computer-assisted learning and experiential learning; ATIs and discovery learning; and learning…

Discussion of computer simulations used for exploratory learning focuses on the design of a hypothesis scratchpad that students can use for hypothesis generation and testing. An experiment with college chemistry students that compared three versions of the scratchpad is described, and the effect of the scratchpads on learning environments is…
