A model of verbal performance was developed which defined cognitive processes thought to underlie performance on the Word Knowledge and Paragraph Comprehension subtests of the Armed Services Vocational Aptitude Battery (ASVAB). The items from two forms of these ASVAB verbal subtests were rated on five conceptualized cognitive storage processes:…

This paper introduces a probabilistic model that is capable of diagnosing and classifying cognitive errors in a general problem-solving domain. Item response theory is used to deal with the variability of response errors. Responses from a 38 item fraction addition test given to 595 junior high school students are used to illustrate the model.…

This report was part of the total scope of The Microcomputers and Middle School Problem Solving project. It employed representational models during problem solving in order to study: (1) observable patterns in self-directed use of representational models; (2) correlations between use of models and problem-solving ability; and (3) the motives of…

Abstracts of most of the papers presented at the 58th annual meeting of the National Association for Research in Science Teaching (NARST) have been collected in this publication. These papers related to such areas as: science curriculum development, design, and implementation; science test development; factors influencing student science…

This document reviews the major trends of thought concerning first and second language acquisition, in an attempt to trace a sequential history to second language teaching methodology today. The contributions of the behaviorist and nativist schools of thought are examined in particular, and two major issues are focused upon: (1) the origins of…

The paper provides a brief discussion of research conducted in child language acquisition at the University of California at Davis in the winter and spring of 1977. The research was directed at children's comprehension of WHY questions. It was an attempt to define when and how children come to understand abstract concepts, such as WHY questions.…

This paper is concerned with the role of speech in the development of control of cognitive processes, with particular attention paid to the nature of bilingualism. It is stated that exposure to a second language provides a way of overcoming the encapsulation of the mind that develops when an individual is exposed to only one language. In order to…

A pre/post experimental-control design was used to evaluate a social studies curriculum based upon inquiry methods. Subjects were 308 eighth-grade students. The results indicated that there were no significant changes in creative thinking, attitudes toward power, understanding of power concepts, and problem-solving skills as a result of experience…

Pedagogical grammar is the presentation of grammatical information for teaching purposes. Two important distinctions are relevant here: reference books versus teaching grammars programmed into a course, and generalized versus specialized grammars, (depending on the extent to which they have been designed to meet specific teaching/learning…

This research examined the nature of the "self-fulfilling prophecy" by investigating how the gradual accumulation of information and the relationship of the source and content of information may affect teachers' perceptions and ratings of trust, social ability, and academic ability of individual students. The study sought to answer two…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 26 titles deal with a variety of topics, including the following: (1) a structured and an unstructured approach to kindergarten instruction and their effects on reading readiness for the first grade; (2) effects of exposure to…

The effect of cultural background knowledge on comprehension and on the language of recall was investigated using an oral presentation. Fifteen Aboriginal women in northern Australia and 15 American women in an adult education class in Illinois were matched in age and educational level. Two stories were read aloud to the subjects, each based on…

Research on the development of ability to control variables during adolescence is reviewed. The first section discusses studies by Piaget and his collaborators, replications of Piaget's studies, and related studies by other investigators. Factors which influence performance on controlling variables tasks are delineated; the existence of Piaget's…

A detailed description is provided of the variable, constructivism versus behaviorism (CVSB), which is part of the analysis in phase I of the Evaluation of Practices in Individualized Schooling. The variable is defined; the questionnaires on which the variable is based are listed; the procedures used to scale the variable are explained; the…

Although teachers may sequence instructions carefully, they are unable to respond to the complex unique experience of each individual learner. Divergent production should be an instructional choice that enables individuals to learn through their own recall and idea construction. Learning is problem solving; when individuals do not know how to deal…
