A model of classroom characteristics and interaction is used to examine the roles of group size, problem types, and student behaviors, central concerns in problem-based learning, in medical education. The model incorporates six classroom dimensions, including four process variables (classroom organization, learning task, teacher's instruction,…

Presents an introductory lesson on remote sensing and image processing to be used in cooperative groups. Students are asked to solve a problem by gathering information, making inferences, transforming data into other forms, and making and testing hypotheses. Includes four expansions of the lesson and a reproducible student worksheet. (MKR)

This paper is a critique of problem-based learning and focuses on, first, the concept of life as problem-governed and professional practice as problem-solving; and, second, the utility of problem-based learning as a pedagogical approach in pre-professional training. The paper suggests that a problem-based approach to professional education is…

This paper reports on five related studies on upper elementary school students' beliefs about the role of real-world knowledge in solving mathematical word problems, and on possibilities of overcoming their unrealistic mathematical modeling. Findings from the first study of 75 Belgian fifth-grade students showed that as a consequence of current…

Imagery use in high school mathematics classrooms was studied. A visual image was defined as a mental scheme depicting visual or spatial information, but this definition was not spelled out to teachers or students, in order to learn what they meant by the concept. Subjects were 13 high school teachers and 54 of their students interviewed over 3…

Interactive multimedia (IMM) and problem-based learning (PBL) are both promoted in response to the current need to offer authentic and effective professional education. An emphasis on collaborative work in PBL contexts may have discouraged the application of IMM, more commonly designed for individual use. This paper describes preliminary…

This paper describes a computer-supported environment designed to facilitate distance learning through collaborative problem-solving. The goal is to encourage distance learning students to work together, in order to promote both learning of collaboration and learning through collaboration. Collaboration is defined as working together on a common…

Higher order cognitive development and success in the study of high school mathematics and science require an understanding of rational number concepts and facility with proportional reasoning and computation. Proportional reasoning is an essential schema for developing formal operational thought. This study involving 16 ninth-grade students was…

The Global Thinking Project at Georgia State University and the Department of Middle Secondary Education and Instructional Technology sponsored a Symposium on Global Thinking Research, in November, 1993. The following 11 papers were presented at the symposium: (1) "Teaching Students to Think Globally" (Jack Hassard); (2)…

A study examined career transitions within organizations. Developed and evaluated during the study was a model that views career transitions as a stress-coping process influenced by work and non-work factors. Data from organizational records, a questionnaire, and performance ratings were collected for 109 managers and professionals in a…

Examining the effectiveness of an organizational development plan, this study notes the changes in school climate in two Pennsylvania schools--a junior high and a middle school. Having selected the schools for their troubled educational environments, the authors gathered data for 2 years from interviews with students and staff, from a formal…

The Student Study Team (SST) is a school site team which involves parents, students, and teachers working together to assist regular education students who are not progressing satisfactorily. The SST model aims to increase positive outcomes for students; improve the quality and efficiency of meetings; and increase personal satisfaction levels for…

The study examines the rule space model, a probabilistic model capable of measuring cognitive skill acquisition and of diagnosing erroneous rules of operation in a procedural domain. The model involves two important components: (1) determination of a set of bug distributions (bug density functions representing clusters around the rules); and (2)…

This handbook provides 25 hours of training in human relations skills for transitional black women (the population of women who are underemployed, unemployed, undereducated, poor, or unaware of educational or occupational opportunities available to them). The purpose of the training is to emphasize image building and human relations skills as well…

This investigation capitalizes upon the information processing models that depend upon measurement of latency of response to a mathematical problem and the decomposition of reaction time (RT). Simple two term addition problems were presented with possible solutions for true-false verification, and accuracy and RT to response were recorded. Total…
