Examines trends in the design of database management systems for microcomputers and predicts developments that may occur in the next decade. Possible developments are discussed in the areas of user interfaces, database programing, library systems, the use of MARC data, CD-ROM applications, artificial intelligence features, HyperCard, and…

Advantages and disadvantages of standard Rasch analysis computer programs are discussed. The unconditional maximum likelihood algorithm allows all observations to participate equally in determining the measures and calibrations to be obtained quickly from a data set. On the advantage side, standard Rasch programs can be used immediately, are…

During the school year 1977/78 four computers equipped with LOGO and Turtle Graphics were installed in an elementary school in Brookline, Massachusetts. All sixth grade students in the school had between 20 and 40 hours of hands-on experience with the computers, and the work of 16 students ranging from intellectually gifted and average to learning…
