the goal of this study was to investigate the effect of using computer conceptual maps­, compared with  usual way of drawing them by pencil and paper­, in increasing learning, recalling and educational progress motivation in geology course among high school students. the study was conducted in semi experimental method in which students of 3 classes were classified in 3 groups. (group 1: common ...

We present the results of a weak lensing survey of six high-redshift (z > 0.5), X-ray selected clusters of galaxies. We have obtained ultra-deep R-band images of each cluster with the Keck Telescope, and have measured a weak lensing signal from each cluster. From the background galaxy ellipticities we create two-dimensional maps of the surface mass density of each cluster. We find that the subs...

We present a new form of summarization for scientific domains in the form of conceptual maps which model the hierarchy and the relations among problems and solutions in a domain as presented in scientific articles.
