A preliminary scheme for estimating the speech intelligibility of hearing-impaired speakers from acoustic parameters, using a computerized artificial neural network to process mathematically the acoustic input variables, is outlined. Tests with 60 hearing-impaired speakers found the scheme to be highly accurate in identifying speakers separated by…

This study elaborates the "what works?" question by exploring the effects of variability in program implementation quality on achievement. Particularly, the effects on achievement of computerized assessment of reading were investigated, analyzing data on 51,000 students in Grades 1-12 who read over 3 million books. When minimum implementation…

The videodisc, audiodisc, overlapping instruction, mapping, adaptive testing strategies, intricate instructional branching, and complex media selection models are common expectations for quality courseware today. A two team development structure, consisting of an instructional development team and a test development team, is proposed. This paper…

Explores how a set of possible student misconceptions about solving a complex problem can be used in computer-based intelligent tutoring systems and in computer-based exercise and test generation. Topics discussed include expert systems, misconception covers, discrimination trees, methods of acquiring the set of misconceptions, and protocol…

Describes a project at Chorleywood College (England) which examined the possibility of automating the transcription of braille examination responses for marking by examination boards. Discussion covers the braille code, requirements of the transcription system, an analysis of mock examination papers which led to system modification, and the final…

Investigated: (1) immediate and continuing benefits associated with using microcomputer-assisted testing with 42 biology students; (2) types of students benefiting from microcomputer-administered diagnostic testing; and (3) the feasibility of microcomputer-administered diagnostic testing. One finding is that such testing positively influences…

There are several points to be considered to prevent misuse when integrating microcomputing into the assessment process. Computerizing an activity does not automatically improve that activity. Computer use is appropriate for computing test scores and storing student data but not for interpreting data. (JDD)

Item analysis procedures appropriate for domain-referenced classroom testing are described. A conceptual framework within which item statistics can be considered and promising statistics in light of this framework are presented. The sampling fluctuations of the more promising item statistics for sample sizes comparable to the typical classroom…

Educational item banking presents observers with a considerable paradox. The development of test items from scratch is viewed as wasteful, a luxury in times of declining resources. On the other hand, item banking has failed to become a mature technology despite large amounts of money and the efforts of talented professionals. The question of which…

In this report, selection theory is used as a theoretical framework from which mathematical algorithms for tailored testing are derived. The process of tailored, or adaptive, testing is presented as analogous to personnel selection and rejection on a series of continuous variables that are related to ability. Proceeding from a single common-factor…

School psychologists and education students and faculty were asked to distinguish between computer-generated and individually written psychological test comments and indicate cues used in making identifications. Even though results indicate correct identification did not differ significantly from chance, school assessment reports must provide more…

The purpose of this paper is to describe some of the current changes in test development that are taking place because of the availability and capabilities of computers, especially microcomputers. Item banking and test assembly are discussed, and a comprehensive testing system is described. (BW)

Approaches proposed for educational diagnostic assessment are reviewed and identified as deficit assessment and error analysis. The development of diagnostic instruments may require a reexamination of existing psychometric models and development of alternative ones. The psychometric and content demands of diagnostic assessment all but require test…

Four computer-animated tasks were created to analyze the underlying structure of emerging phonological awareness at 3.5 years of age and to explore factors that influence children's (n=91) performance. The children were able to master tasks demanding identification, blending, and continuation of phonological units. Analysis supported two major…

This article describes a prototype videodisc method of assessing social competence, knowledge, and perception in children with disabilities. It notes major hardware features (Macintosh IIx computer), software features (using SuperCard), improved examinee response modes, and improved data entry techniques. (DB)
