Recent work has shown that multidimensionally scoring responses from different tests can provide better ability estimates. For educational assessment data, applications of this approach have been limited to binary scores. Of the different variants, the de la Torre and Patz model is considered more general because implementing the scoring procedure…

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

This study identified and examined the validity of a Brunerian theory-based, aptitude-enhancing, standardized educational simulation by assessing spatial visualization ability of students assigned to simulation and non-simulation treatment groups. Results indicate the simulation increased high aptitude learners' efficiency (and initially…

This study investigated the effects of three instructional strategies and student entry characteristics on student engagement and the acquisition of skills necessary for the construction and interpretation of line graphs. The strategies examined were an activity-based approach, a written simulation-based approach, and a combination of activity-…

Recounts an experiment where two groups of college students composed questions for a simulated quiz show and then answered each other's questions. They then answered questions comparing their performance with other groups. Proposes a social norm rather than attribution error explanation for the fact that groups consistently will underestimate…
