This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)
