The scale of features shown on outcrop photographs can be critical to geoscience interpretations, yet little is known about how well individuals estimate scale in images. This study utilizes a visualization test in which participants were asked to estimate the absolute size of several boxes shown in outcrop images using high resolution, stitched…

This paper reports a quantitative study on gender differences in attitudes when learning oral skills via technology. The study was conducted at Tafila Technical University, Jordan, with 70 female and 30 male students, to find out if female students are better and faster in learning a language than male.

In theoretical models of self-regulated learning, calibration is one important component in successful learning. Two issues of calibration are explored. First, Nelson (1987) suggested the "G" (gamma) coefficient is the most appropriate measure of calibration (judgment accuracy) and rejected signal detection theory's "d'"…

A 4 x 4 factorial experiment was conducted with 152 college age volunteers to investigate the effects of different forms of mathemagenic information (algorithms, heuristics, attribute elaboration, and attribute isolation) on concept acquisition. Results showed that both definition and instance presentation had a significant effect on students'…
