During spatial reorientation, the use of local geometric cues (e.g., corner angles) and global geometric cues (e.g., principal axis) is differentially influenced by enclosure size. Local geometric cues exert more influence in large enclosures compared to small enclosures, whereas the use of global geometric cues is not influenced by changes in…

We examined the preference of undergraduate students for a live or a virtual rat when learning about concepts of operant conditioning. Students were provided with the opportunity to directly compare a virtual and a live rat in a supplemental exercise for Learning courses. We argue that the design of teaching exercises should involve a systematic…

Are virtual manipulatives as effective as concrete (hands-on) manipulatives in building conceptual understanding of number concepts and relationships in pre-service middle grades teachers? In the past, the use of concrete manipulatives in mathematics courses for Clayton State University's pre-service middle grades teachers has been effective in…
