The cognitive model of depression postulates that the depressed individual's cognitions are not only negative, but erroneous and impervious to information from the environment. However, the valence of that information ultimately determines whether those cognitions are impervious or merely receptive. The actual life circumstances of the depressed…

Several central ideas emerging from a systematic approach to teaching problem-solving in the quantitative sciences (chemistry, physics, engineering) are discussed. Areas addressed include: differences between teaching and performance, between naturalistic and effective functioning, and between detailed observations and gross statistical data;…

In order to compare the differences in cognitions of experienced and beginning teachers, the perceptions of six experienced teachers, six student teachers, and six probationer teachers (in their first year of teaching after college training) were studied at various times during the course of a school year, using a variety of methods (interview,…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on the concepts of "living" held by 32 students in four different…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on students' thinking regarding their views on friction. Students (N=47) were…

Introduction: We report on a small-scale research project which examined the impact of mobile technologies on the users' experience of information overload. The project focused on a group of worker who have had relatively little attention in both the mobile technology and information overload literatures: senior managers. Method: The case study…

Preliminary psychometric data assessing the reliability and validity of a method used to measure the diagnostic reasoning and problem-solving skills of predoctoral students in orthodontia are described. The measurement approach consisted of sets of patient demographic data and dental photos and x-rays, accompanied by a set of 33 multiple-choice…

This study of the Apple Classroom of Tomorrow (ACOT) environment focused on the potential of a computer-saturated environment to facilitate students' thinking processes. Four approaches were used: (1) a longtitudinal approach to study student growth and development; (2) observations of students' behavior while writing with the computer to study…

This paper reports on the effects of structuring problem solving activities of novices in the domain of physics in a way consistent with the problem solving approaches used by experts. A total of 42 undergraduate students who completed a first semester physics course and received a grade of B or better participated in this study. The treatment…

A study of 228 undergraduate psychology students examined the effectiveness of a prototype of "heatlab," a laboratory simulation written in PCE-PROLOG, intended for remedying misconceptions of the concepts "heat" and "temperature." The effect of varying the amount of structure on students' understanding and the…

This study compared the effects of cooperative learning groups to traditional instruction in remediating students' misconceptions about temperature. Students from grades 3, 4, and 5 in two rural elementary schools participated in the study. Students completed a pretest, a cognitive conflict laboratory activity and a posttest that measured…

Intended to help professionals remain knowledgeable about current research in reading and to serve as a relatively accessible bibliographic source of research on a specific topic, this annual report summarizes approximately 800 reading research reports identified between July 1, 1985, and June 30, 1986. The summaries are arranged into six major…

Arguments for and against banning television commercials aimed at children under age 12, as well as the role of the Federal Trade Commission (FTC), the First Amendment, and parents in regulating such commercials, are explored in this paper. Following an introduction that describes the controversy, a second section of the paper details the…

Current issues in educational communications and technology are addressed in this collection of 47 conference papers in which research reports predominate. Topics discussed include factors related to the learner, e.g., learning strategies, information processing, spatial ability, cognitive style, and cognitive strategies. Presentation format and…

This research paper examines hidden cultural patterns establishing the expression of historical thought in Native Alaskan narratives which describe first contact with Russians. Historical consciousness in oral contact stories is always mythic in form, as well as in content. Native American oral cultures understood new events by…
