The scientific and technical publications summarized in this report describe research on intelligent instructional systems sponsored by the Personnel and Training Research Programs, Psychological Sciences Division, of the Office of Naval Research. Abstracts of the following papers are presented: (1) "Understanding Reflective Problem…

A study investigated the effects of nonverbal and verbal classification abilities on reading comprehension. Subjects, 104 fourth grade students, were tested on three measures of classification skill (a shifting of criteria task, a free sorting task, and a three-level hierarchical classification task) and on a measure of recall of relevant story…

Different aspects of human-machine interaction are discussed in the five brief papers that comprise this report. The first paper, "Some Observations on Mental Models," discusses the role of a person's mental model in the interaction with systems. The second paper, "A Psychologist Views Human Processing: Human Errors and Other…

A group of 24 14-year-old students were presented with sets of algebra tasks using the Leeds Modelling System (LMS), a computer-based modeling system. Four months later, these same students were given a paper-and-pencil test which covered comparable tasks set by LMS. In addition, certain students were given detailed diagnostic interviews. A…

This paper reports the results obtained with a group of 24 14-year-old students when presented with a set of algebra tasks by the Leeds Modelling System (LMS). These same students were given a comparable paper-and-pencil test and detailed interviews some 4 months later. The latter studies uncovered several kinds of student misunderstanding that…

This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

This study used the Montague-Riley Test to introduce a new scoring procedure that revealed errors in cognitive processes occurring at subcomponents of an electricity problem. The test, consisting of four parts with 36 open-ended problems each, was administered to 250 high school students. A computer program, ELTEST, was written applying a…

The historical development and recent applications are described of the picture sequencing format (PSF), a testing device which requires the subject to designate a complete and correct order for a set of related pictures. The earliest use was by Decroly in 1914 and perhaps the best known use is in the Wechsler intelligence tests. Special…

THE RELATIONSHIP OF PATTERNS OF COGNITIVE PROCESSES AND PERSONALITY TRAITS WERE INVESTIGATED IN THIS STUDY OF 6 GROUPS OF CHILDREN (120) IN GRADE 5. SCORES ON THE PRIMARY MENTAL ABILITIES TEST, IOWA ACHIEVEMENT TEST, AND CALIFORNIA TEST OF MENTAL MATURITY WERE USED AS MEASURES OF COGNITIVE PROCESSES. (JK)

PRELIMINARY ANALYSES WERE UNDERTAKEN TO DETERMINE THE POTENTIAL CONTRIBUTION OF MOTION PICTURE FILMS TO FACTOR ANALYTIC STUDIES OF HUMAN INTELLECT. OF PRIMARY CONCERN WERE THE OPERATIONS OF COGNITION AND MEMORY, FORMING TWO OF THE FIVE OPERATION COLUMNS OF GUILFORD'S "STRUCTURE OF INTELLECT." THE CORE REFERENCE FOR THE STUDY WAS DEFINED…

Standardized norm-referenced tests have been much maligned in recent years. They differ from criterion referenced tests in that the latter involve assessment in comparison to an absolute standard or specific performance objective while in a norm-referenced test assessment is made in comparison to other students taking the same test. Standardized…

To investigate intelligence level, academic achievement, nonacademic achievement, ideational productivity, and the uniqueness of the ideas produced, a sample of 503 incoming freshman university students was recruited. Intelligence was measured by using students' Scholastic Aptitude Test scores; verbal and visual stimuli were used to elicit ideas.…

Arguments for the use of sequential ordinal scales in the observation of infants and young children are based on the tendency of traditional psychometric assessment to distract investigators from discerning structural and hierarchical aspects of development. Norm-referenced testing focuses on interindividual comparisons rather than developmental…

Sixth-grade students were measured on fluid and crystallized ability, given instructions stressing one of the abilities, and pre- and posttested on a mathematical concept. Results suggest that students with lower general ability benefit most by instruction focused on fluid ability, and students with higher general ability by instruction focused on…

Describes a study of 323 fifth and sixth grade students which was conducted in Australia to examine cognitive processing of gifted children compared with normal and above average ability children. Highlights include the role of planning in cognition, tests used, and a factor analysis of results. Fifty-one references are listed. (Author/LRW)
