Naturalistic observation techniques were used with 24 9- to 12-year-old learning disabled students to investigate two sets of variables that might influence achievement differences between computer-assisted instruction and seatwork: engagement rate and interactions with teachers and peers. Implications for research and microcomputer implementation…

Describes study that was conducted to examine the effects of animation and practice on factual and application learning in elementary science computer-based instruction (CBI). The extent to which animation and practice promoted near and far transfer of learning outcomes is explored, and effects on processing time are examined. (31 references) LRW)
