Criticizes the Mitchell and Lawson (1988) report from the viewpoint of individual interview method. Provides Lawson's reply to the comment by showing differences in research philosophy and methods. (YP)

In a previous study (Watson, 1960), college students were told that a three-number string ("2, 4, 6") conformed to a rule and that they had to guess the rule by proposing other three-number strings; they were then told whether each guess was right or wrong. However, it was suspected that, since the subject's hypothesis was falsified by…

Mathematics learning objectives and specifications for third graders, which are congruent with the Texas "State Board of Education Rules for Curriculum," are presented. They are designed for use by teachers and test development specialists involved with the preparation of the Texas Educational Assessment of Minimum Skills (TEAMS) tests.…

Learning objectives and specifications are provided for use by teachers and test development specialists. Beginning with the 1985-86 school year, the Texas Educational Assessment of Minimum Skills (TEAMS) tests have been based on the objectives in this publication. For grade 9 mathematics, these objectives are: (1) identify the relationship among…

Beginning with the 1985-86 school year, the Texas Educational Assessment of Minimum Skills (TEAMS) tests have been based on the objectives provided in this publication for teachers and test development specialists. For grade 7, mathematics objectives include the ability to: (1) convert decimals or percents to equivalents; (2) add and subtract…

Results of 120 studies were combined by meta-analysis to determine effects on mathematics test performance of factors other than knowledge of content. Conditions that enhanced performance included testwiseness training, praise, word problem pictures, and frequent testing. Conditions depressing or not affecting performance were also noted. (MNS)

Two experiments investigated relationships between state anxiety, memory processes, and children's performance on problem-solving tasks. Participants were second and sixth graders in a private elementary school in Redlands, California. In both experiments, subjects responded to three training and eight test problems presented in the introtact…

College students were given two paper-and-pencil conditional reasoning tests, one week apart, in varying order. The three problems on each test were presented either verbally or with line drawings as concrete referents. Performance was significantly poorer on the problems with drawings. (MNS)

Arguing that sufficient theory exists about the interplay between human information processing, computer systems, and the demands of various tasks to construct useful theories of human-computer interaction, this study presents a structural model of human-computer interaction and reports the results of various statistical analyses of this model.…

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…

This study, which assessed hypothesis-testing abilities using a discrimination-learning paradigm, found that 16 language-impaired primary-level children solved fewer problems than 16 controls equated on cognitive level, but the 2 groups used similar hypothesis types to solve the problems. Type of verbal feedback (explicit versus nonexplicit) did…

This report investigated the relationship between learning to program LOGO and the development of problem solving skills. Subjects were 133 students in grades 4-8 who had at least 30 hours of experience with both graphics and lists programming in Logo. Students were randomly assigned to one of three contextual groupings, which received graphics,…

This study examines the nature of the highly variable black-white difference across diverse tests and indicates the major systematic source of this between-population variation, namely, Spearman's g. Eleven large-scale studies (discussed in the appendix), each one comprising anywhere from 6 to 13 diverse tests, show a significant and substantial…

Although the distinction between verbal ability and spatial ability is fundamental in all models of human abilities, differences in the relative strengths of verbal and spatial abilities have failed to show consistent interactions with instructional treatments. This study investigated the hypothesis that spatial tests measure different abilities…

Compares experts', advanced students', and novice students' use of genetics knowledge to generate and test hypotheses while solving genetic pedigree problems. Reports that experts identified more critical cues, tested more hypotheses, were more rigorous in the falsification of alternative hypotheses, and were more flexible to their solving…
