The nonparametric approach to test theory discussed here has its roots in the early work of Guttman, Lazarsfeld, and Meredith; and more recently in the work of Cliff and in Tatsuoka and Tatsuoka. Mokken's extensive treatment of this subject concentrated on defining, constructing, and testing unidimensional scales, based on responses to dichotomous…

A "Xenograde system" is an imaginary science system. As an imaginary science, it contains a set of concepts and principles which mimic many of the concepts and principles found in physics and other physical sciences. Xenograde is a highly complex closed system which simulates the movement of satellites orbiting a nucleus and some small particles…

This study was designed to learn if students perceived an interactive computer/videodisc learning system to represent a viable alternative to (or extension of) the conventional laboratory for learning biology skills and concepts normally taught under classroom laboratory conditions. Data were collected by questionnaire in introductory biology…

Discusses reliability and validity of continual response measurement (CRM), a computer-based measurement technique, and its use in social science research. Highlights include the importance of criterion-referencing the data, guidelines for designing studies using CRM, examples typifying their deductive and inductive functions, and a discussion of…

This study, part of a longitudinal investigation, examined the kinds of thinking which children aged 10 and 11 could carry over from Logo instruction to an algebraic context. Interviews focused on their ability to construct meaningful symbolization for the concept of variable and to construct formalized algebraic rules. (MNS)

Discusses the application and use of a microcomputer-assisted reference statistics procedure which allows for customized programs to be designed and determined by local, unique research objectives, service demands, and the ultimate use of the recorded data. A literature review of the development and use of reference statistics is included. (EM)

Secondary teachers in a workshop on overcoming computer and math anxiety and students in a programming course were given measures of anxiety and achievement. Low mathematical ability and coursework were related to math and computer anxiety and negative attitudes. Attitudes improved for the teachers but not the students. (MNS)

Reviews approaches to machine learning (development of techniques to automate acquisition of new information, skills, and ways of organizing existing information) in symbolic domains. Four categorical tasks addressed in machine learning literature are examined: learning from examples, learning search heuristics, learning by observation, and…

This paper presents a review of the literature regarding use of computers in elementary social studies and a rationale of how computer usage aligns with the constructivist approach to education. Computer use in elementary social studies can be divided into three broad categories: (1) instructional software; (2) productive software; and (3)…

This paper describes a computer support system that eliminated many of the problems associated with the usual methods of transcribing and analyzing questionnaire data. The system was created to support the course evaluation system at Athabasca University, a distance education university in Canada. The courses evaluated were all home study courses,…

Described is the notion of multiple alternative representations of mathematical reasoning, particularly as they relate to algebraic notation and the potential of computers to change representations. Features of a desirable notation for algebraic problem solving are described. This is followed by a description of the RAND Corporation's intelligent…

Because there is little theoretical background to explain the process of adopting computers for instruction in postsecondary institutions, this paper reviews the literature on this process from the perspective of technological innovation. Technological innovation is defined as the use of tools and techniques which extend human capability and which…

As part of an ongoing effort to understand the processes people employ in reading technical material and the ways in which computer based job aids can assist people in doing complex tasks, a study was conducted to determine how subjects engaged in an assembly task use a detailed and hierarchically organized information structure (Hypertext) to…

This study describes a computer based, performance rating information processing system, performance rating theory, and programs for the application of the theory to obtain ratings free from the effects of reviewer stringency in reviewing abstracts of conference papers. Originally, the Performance Rating (PR) System was used to evaluate the…

The use of Relational Database Management Systems (RDBMS), a type of microcomputer application software, to analyze open-ended survey questions is discussed. Using open-ended questions allows researchers to ask respondents to express themselves freely about their attitudes and beliefs. This approach also can elicit a precise answer even though the…
