Described is research which sought to prove the hypothesis that mental models tend to preserve their autonomy with regard to the originals they are meant to represent. The results of this investigation involving 200 Israeli students are presented. (CW)

A five-step model intervention called "Sensational Thinking," which incorporates readiness, reception, reflection, revelation, and re-creation activities, was evaluated with four kindergarten classes. Experimental groups showed increased creativity over control groups in solving paradoxical problems. The study is seen as supporting the premise…

This paper presents four studies which illustrate the variety of deficits in executive function displayed by individuals with autism. The concept of executive function is used to encompass all the mental operations which are involved in self-reflective and goal-directed behavior. Four forms of executive control are addressed: mental disengagement,…

This paper examines issues involved in selecting a strategy that could be carried out by institutions to achieve salary equity between male and female faculty. It compares potential strategies based on equity of salary adjustments, political constraints, cost to the institution, and whether the plan removes inequities. Steps in determining…

The paper presents the thesis that experienced physicians, while diagnosing routine cases, are operating upon knowledge structures that are distinctively different from those of novice physicians and students. In the course of their medical training, students develop rich, elaborated causal networks, explaining the causes and consequences of…

This report summarizes research on experienced programmers' comprehension of computer programs that was carried out over a three-year contract period (1982-85). Following an extensive review of the programming skill literature, an analysis of programs based on the multiple abstractions (points-of-view) that characterize program text and design was…

Seventeen research reports are arranged under several broad topics of mathematics education. Section 1 concerns language and mathematics learning, with one paper on word problems and one on concept formation. Papers on university level mathematics in Section 2 explore problem solving, characteristics of school leavers, some mathematical aspects of…

Preliminary results from a study of students' conceptions in introductory rotational physics are discussed. Analyses of data from problem solving interviews and written diagnostic tests provided evidence that many students had a poor qualitative understanding of torque. Even among students who answered questions correctly a percentage did so for…

A formally conducted field study was used to investigate the work of vice-principals of eight large Southern California high schools and the relationship of their work to the school as an organization. Most of the vice-principals studied deal with student discipline, but four have important discipline responsibilities, which they exercise by…

A computer assisted system called PEERRATE was used in a theater history course at Rutgers, the State University of New Jersey in Newark, in fall 1980, in order to give students an opportunity to anonymously grade one another's written work and to compare their own ratings with those of fellow students and the instructor. The PEERRATE system is a…

Of the many specific situations in which the exercise of suasory influence may be necessary to assure that a decision making group meets its analytical responsibilities, five appear to be particularly important. These are circumstances in which (1) a group is violating accepted procedural norms, (2) an authority figure or high status group member…

This study aims to explore leadership characteristics and contribute evidence to the validity of Jungian personality typology by investigating the relationship between principals' personality types and their reported problem-solving strategies. To test the hypothesis that the manner in which the principals report that they would solve a problem…
