Much of the debate over interactive television has focused on immediate push-button access to a wide range of high quality, full motion video programs. Public broadcasters need to position themselves for the coming age of digital transmission; they can do this by concentrating on transition services that offer increased interaction with less risk…

In Boston and other markets around the country, most formats have subdivided into targeted niches. The effect has been to even out station shares, so that rather than trying to reach mass audiences,…

These FORTRAN programs and MATHEMATICA routines were developed in the course of a research project titled "Achievement and Assessment in School Science: Modeling and Mapping Ability and Performance." Their use is described in other publications from that project, including "Latent Traits or Latent States? The Role of Discrete Models…

Like other industries, television has its own version of the used-car dealership or second-hand store: off-network syndication. Since researchers who study television have rarely investigated the market for these programs, a study examined program and marketplace characteristics to determine which contributes most to the successful syndication of…

One answer among many is through the writing of computer programs. The writing of computer algorithms is mathematical problem solving and logic in disguise and it may attract students who would otherwise stop…

A method based on 0-1 linear programming (LP) is presented to stratify an item pool optimally for use in "alpha"-stratified adaptive testing. Because the 0-1 LP model belongs to the subclass of models with a network-flow structure, efficient solutions are possible. The method is applied to a previous item pool from the computerized…
