The purpose of this research study was to examine the overall effect of adaptive learning systems deployed using artificial intelligence technology across a range of relevant variables (e.g., duration, student level, etc.). Following a systematic procedure, this meta-analysis examined literature from 18 academic databases and identified N = 45…

This study sought to test the most efficient representation mode with which children with hearing impairment could express a story while producing connectives indicating relations of time and of cause and effect. Using Bruner's (1973, 1986, 1990) representation stages, we tested the comparative effectiveness of Virtual Reality (VR) as a mode of…

The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

Describes the design of a hypermedia tool for helping preservice teachers learn about the growth and development of children's mathematical reasoning based on research in cognitive science, and discusses results of an experiment that used single-subject methodology to compare preservice teachers' learning with the hypermedia tool versus learning…

This study examined the instructional effectiveness of three software learning environments--LOGO, drill and practice, and teacher-directed activities--for preschool special needs children. Cognitive distancing was applied to classify children and child-software interactions; dependent measures included indicators of problem solving, skill…
