Digital image processing offers several possible new approaches to the teaching of a variety of mathematical concepts at the middle-school and high-school levels. There is reason to believe that this approach will be successful in reaching some "at-risk" students that other approaches miss. Since digital images can be made to reflect almost any aspect of the real world, some students may have an easier time taking an interest in them than they might with artificial figures or images resulting from other graphics- oriented approaches. Using computer-based tools such as image processing operators, curve-fitting operators, shape analysis operators, and graphical synthesis, students may explore a world of mathematical concepts starting from the psychologically "safe" territory of their own physical and cultural environments. There is reason to hope that this approach will be particularly successful with students from diverse backgrounds, girls and members of minority groups, because the imagery used in experiments can easily be tailored to individual tastes. The work of the project consists of creating detailed designs of the learning modules, implementing them on microcomputers, and evaluating their effectiveness in a variety of ways, using trials with students at Rainier Beach High School, which is an urban public high school having an ethnically diverse student body and a Macintosh computer laboratory.

This project will explore new ways to reach a broadcast audience wider than those who normally would watch an NSF funded television program on PBS. The PI will define new, non-competitive relationships between PBS and other broadcast or cable venues and will explore incentives for pursuing such relationships. The specific tasks to be conducted under the grant include: developing and testing procedures for distributing a program or series in a venue in addition to PBS, implementing such distribution, and evaluating the impact on audience size in the new venue as well as on subsequent broadcast on PBS. The final report will document the results of this research and describe the steps required to arrange for multiple venues. This project represents examination of an untested idea, the results of which may establish the basis for significantly increasing the impact of broadcast programming supported by NSF. Traditionally, when PBS has agreed to schedule a program or series, they have insisted on a window of exclusivity for a period three years. If the data from this project indicates that broadcast of a PBS program in a new venue reaches new audiences and, potentially, attracts some of that audience to PBS, it should establish a more open attitude on the part of PBS toward multiple venues at a much earlier time.
This is part three of the four part "Classroom Activities and Outcomes Survey." The survey asks students to rate the progress they have made in science process skills as a result of completing a particular course or program.
