This paper presents examples of effective uses of microcomputers to support basic statistics instruction. All programs are written in Applesoft BASIC for Apple II Plus microcomputers and compatible equipment. They have been field tested in statistics courses at the University of Maryland. Microcomputers can be used with color monitors for…

This paper presents an explanation of the program design of the three separate Pascal-language programs which comprise UCLA's Diagnostic Testing Package "DX." The three parts of the DX test package are three closely interrelated programs--Editest, Runtest, and Summary. Editest serves the following functions: (1) the creation of a…

The use of computers to build diagnostic inferences is presented in two contexts: (1) closed world, exemplified by the space shuttle launch monitoring system; and (2) open world, represented by computerized diagnostic testing of reading comprehension. The analysis shows that the closed world provides a substantially cleaner environment within…

This paper describes a computer program in Microsoft BASIC which selects and administers test items from a small item bank. The level of the difficulty of the item selected depends on the test taker's previous response. This adaptive system is based on the Rasch model. The Rasch model uses a unit of measurement based on the logarithm of the…

This report and compilation of papers summarizes information collected by an Assessment Development and Use Project, initiated by the Northwest Regional Educational Laboratory (NWREL) to assist test development efforts by state and local agencies. Specific item banking applications are reported in two case studies, selected because they represent…

Discusses the ISCS/FIRN Test Item Database, which contains 10,000 juried science questions that can help teachers prepare tests. Describes the process by which teachers can access the database and download certain questions into their own microcomputer. Provides lists from a sample search done using the various menus available. (TW)
