Designed to determine whether abstract and concrete concepts are classified similarly, this study used three separate experiments to explore the vertical and horizontal dimensions used by computer scientists to categorize the common concepts of their field. It found that concrete concept categorization operates over a wider range than previously…

This study investigated whether computer science educational background makes secondary students more adept at using word processing capabilities, and compared computer science and non-computer science students' writing improvement with word processing use. Computer science students used more sophisticated program features but student writing did…

This brief overview of the state of the art in computer education in schools in the Federal Republic of Germany covers both the extent and areas of use and research and development, and frequent comparisons are made with educational computer usage in other countries, including the United States, Japan, France, Great Britain, and Norway. The…

The sequential probability ratio test (SPRT), developed by Abraham Wald, is one statistical model available for making mastery decisions during computer-based criterion referenced tests. The predictive validity of the SPRT was empirically investigated with two different and relatively large item pools with heterogeneous item parameters. Graduate…
