In the study, a part of longitudinal research focused on the emergence of mathematical knowledge structures in a learner's mind is presented. It concentrates on the analysis of introspective data gained from the author's study of a non-standard arithmetic structure in terms of the model of abstraction in context (Hershkowitz, Schwarz and Dreyfus).…

This document consists of the two issues of the "AMATYC Review" published during volume year 1997-1998. Designed as an avenue of communication for mathematics educators concerned with the views, ideas, and experiences of two-year college students and teachers, this journal contains articles on mathematics exposition and education, and regularly…

This report describes the decision-making model that provides the theoretical framework being developed by the Early Childhood Research Institute on Measuring Growth and Development (ECRI-MGD) in a 5-year project to generate a set of common child and family indicators that can be used within a comprehensive system of service delivery for young…

This paper proposes the use of specific coaching strategies to facilitate students' use of expert-like problem-solving strategies while analyzing and solving instructional design case studies. Findings from an exploratory study, designed to examine changes in students' problem-solving skills as they analyzed case studies, suggested that students…

This paper discusses a two-semester integrated mathematics content and methods course for preservice elementary school teachers taught for the past twenty years at Saint Xavier University. The course material is presented in a problem solving format in a laboratory context with students working with manipulative materials as part of cooperative…

In their complex nature, early adolescents want to believe in their teachers. Teachers demonstrating what they believe earn respect from students. In science education, it is vital to link scientific phenomena to daily life and social decision making skills to engage students in developing science-process skills. The science-technology- society…

This book reports on the first wave of the Mosaic Project which investigates the effects of educational change and teaching practices in mathematics and science on student achievement. The Mosaic project was supported by the National Science Foundation (NSF) and featured two waves. The states that participated in the first wave were State Systemic…

This paper describes the "Problem Solving for Life" training program which trains adolescents and adults with mental retardation in skills for solving social problems. The program requires group participants to solve social problems by practicing two prerequisite skills (relaxation and positive self-statements) and four problem solving steps: (1)…

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…

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,…

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 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…

Describes classroom approaches for encouraging healthy social interaction: social skills training, and interpersonal cognitive problem solving. Addresses service delivery considerations, such as personnel, purpose, types of children, research and service, and scheduling. (AOS)
