Massively parallel programming languages, like StarLogo, provide a rich environment for introducing differential equations to students with an unsophisticated mathematical background. This paper describes the basic software for stimulating and monitoring various population dynamics. Simple differential equations that describe the observed dynamics…

According to the United States Department of Labor, 73% of drug users in 1997 were employed. Numerous studies, reports, and surveys suggest that substance abuse is having a negative effect on the workplace in terms of decreased productivity; increased accidents; absenteeism; turnover; and medical costs. However, workplace substance abuse is a…

This document focuses on using satellite images from space in the classroom. There are two types of environmental satellites routinely broadcasting: (1) Polar-Orbiting Operational Environmental Satellites (POES), and (2) Geostationary Operational Environmental Satellites (GOES). Imaging and visualization techniques provide students with a better…

Suggesting that using children's literature as a tool for problem solving is a meaningful way for teachers to understand and help children with problems, this Digest claims that through the exploration of stories, discussion, and reflections on their own experiences, children can begin to perceive the complexities of the world in which they live.…

The purpose of this paper is to review evaluation theories and techniques in both the medical and educational fields and to propose an evaluation theory to explain the condition variables, the method variables, and the outcome variables of student assessment in a problem-based learning (PBL) approach. The PBL definition and process are presented,…

This paper presents and discusses two research initiatives in New Zealand elementary schools in terms of factors influencing the path of professional development and sustained attention to information literacy. The first study was a comparison of professional development processes and children's learning outcomes in four elementary schools.…

The problem-solving strategies used by 10 radiologists and 10 radiology residents during the interpretation of difficult mammograms were examined under two experimental conditions. In the "authentic" condition, standard unmarked mammograms were used. On a second set of the same cases for the "augmented" condition, mammographic…

This field trip program consists of a 90-minute interpretive tour and a 90-minute hands-on workshop. The tour and workshop explore the role of water power in the Industrial Revolution. On the tour, students discover firsthand the unique resources of Lowell, Massachusetts, and the Park, while the workshop brings these historic resources to life as…

Spatial thinking is a cognitive skill that can be used in everyday life, the workplace, and science to structure problems, find answers, and express solutions using the properties of space. It can be learned and taught formally to students using appropriately designed tools, technologies, and curricula. This report explains the nature and…

The centrality of assessment for facilitating thinking, reasoning, and problem solving is well-documented and indisputable. Less apparent is how to create informative, yet practical measures for classroom use. Clearly, the changing of assessments alone will not in and of itself improve learning; teachers' beliefs and practices will need to be…

The Program for International Student Assessment (PISA) is a system of international assessments that measures 15-year-olds? capabilities in reading literacy, mathematics literacy, and science literacy every 3 years. PISA was first implemented in 2000 and is carried out by the Organization for Economic Cooperation and Development (OECD), an…

A team consisting of three faculty members from Agricultural Economics, Agribusiness management, and Food Science with two research assistants at Penn State University has been working for three years on creating a food product case library for a problem-based learning and case-based instruction course. With the assistance of experts from the food…

Two activities that provide motivation for drill problem-solving work are described. Solutions to problems are associated with coded letter puzzles which provide instant feedback as well as motivational interest. (JP)

Because activity in the classroom is the primary focus of educational research, and because teachers are critical about the dissemination and implementation of research products, developers must take into account the growth and development of instructional personnel. Educational development is a multidimensional, transactional phenomenon and must…

Impressions of Robert M. Hutchins and his Center for the Study of Democratic Institutions in Santa Barbara. The Center houses a catalytic group of scholars who generate ideas rather than actions. Describes some of their thinking on education, science, retrospective futurology, the use of oceans as a world resource, a new constitution, and the…
