A multiple baseline design investigated the effects of computer graphic organizers on the persuasive composition writing skills of four Hispanic students with specific learning disabilities. Participants reviewed the elements of persuasive writing and then developed compositions using a word processing program. Baseline planning was done with a…

Describes the design and operation of four software packages, or macros, written in the programing language of Microsoft's EXCEL for use on the Macintosh computer for data manipulation and presentation used in educational research. Reordering tabulated data, reversing the scoring of tabulated data, and creating tables and graphs are explained.…

Bender Gestalt Test data from 60 severely emotionally handicapped and 60 normal children were computer digitized and scored traditionally. Reliability results from comparison of analysis techniques favored computer approach; criterion-related validity was unsuccessful for both scoring methods; and concurrent validity results indicated limited…

Computer programs are presented to plot item and test characteristic curves and item information functions for parameter estimates produced by the LOGIST and BICAL computer programs. These programs provide data in tabular format, but their usefulness in test development and measurement courses can be greatly enhanced by graphic plots of the item…

This report includes a collection of workshop materials which address ways microcomputers can be used in evaluation and assessment and what basic information should be covered in introducing newcomers to the use of microcomputers. It is designed for use by experienced trainers with microcomputer experience but with few workshop support materials.…

A multidimensional item response theory (IRT) model for polytomously scored items, based on the graded response model and using the normal ogive, is developed; and an EM algorithm that may be used to estimate the parameters of the model is also discussed. The model is illustrated through a simulation study in which the polytomous item responses of…

The contributions and limitations of computer technology in the presentation of grammar drills, particularly in a second language, are examined by comparing and contrasting the new technology with traditional textbook instruction. It is noted that, in many ways, computer-assisted language learning (CALL) is a derivative form of traditional…
