This paper provides information on the incidence and prevalence of alcohol-related birth defects, the human and economic costs of fetal alcohol syndrome (FAS) and fetal alcohol effects (FAE), and examples of prevention and intervention strategies that can help reduce the occurrence of and ameliorate the consequences of FAS/FAE. It discusses the…

Some researchers have argued that students often learn to operate in two domains, the domain of the science context in school, and the domain of everyday life outside of school. Outside of school, students are exposed to many media from which to learn science concepts. This document is one of a series on research seminars at the Western Australian…

Although students' misconceptions about the concept of chemical equilibrium has been the focus of numerous investigations, few have investigated students' systematic errors when solving equilibrium problems at the college level. Students (n=189) enrolled in the second semester of a first year chemistry course for science and engineering majors at…

The substantial interest exhibited in the last decade in the identification of students' misconceptions of a wide range of scientific concepts has not extended to identification of students' misconceptions of the nature of science itself. This study examined the attitudes of 32 secondary school students, each from Canada, the United States, and…

This bibliography contains some 2,000 articles on empirical investigation and theoretical considerations covering the topic of students' conceptions entered before September 1990. PUblications in journals, books, working papers, and contributions to conferences are included. English, German, and French publications, and ones in other languages are…

The history of academic inquiry into leadership as a discipline has yielded the unintended consequence of compounding confusion and perpetuating the myth of leadership as mystical. This paper takes that acknowledgement and inquires into the past and future of leadership theory development from a systemic perspective to define the concept, propose…

One of the most common misconceptions about probability is the belief that successive outcomes of a random process are not independent. This belief has been dubbed the "gambler's fallacy". The belief that non-normative expectations such as the gambler's fallacy are widely held has inspired probability and statistics instruction that attempts to…

The major perspectives on problem solving of the twentieth century are reviewed--associationism, Gestalt psychology, and cognitive science. The results of the review on teaching problem solving and the uses of computers to teach problem solving are included. Four major issues related to the teaching of problem solving are discussed: (1)…

This study focuses on how students make sense of and understand concepts related to the study of a wetland. The analyses of students' talk and drawings recorded during a 2-week wetland unit were divided into two levels. The first level examined students' understandings and explored student traits that contributed to a clear, stable understanding…

This paper aims to clarify and describe the process of change in learners' conceptual understanding of natural phenomena. It begins by reviewing the existing literature on models of conceptual change and on children's conceptions in a number of selected topic areas. Strategies for exploring and developing children's ideas in these areas have also…

This ERIC Digest describes the parameters of misconception research as it relates to the learning of science and highlights some of its implications for the teaching of science in the elementary school. The document reviews terminology associated with misconception research, identifies common characteristics of misconceptions, and specifies…

Analogies and examples from student's experiences are frequently cited as important to teaching conceptual material. This study was conducted in order to explore the effectiveness of an analogical teaching technique, which uses a connected sequence of "bridging" analogies, compared with a more standard teaching-by-example technique. The…

An analysis of science teacher's knowledge of specific biology and physics topics and the effects of this knowledge on their planning for instruction and on simulated teaching are discussed in this report. Six experienced secondary school teachers participated in the study. Each teacher's knowledge of a biology topic and a physics topic was…

Designed to help in the development of an educational program about the value of rain forests, this handbook presents a condensation of issues, facts, and concepts. The handbook is divided into three parts. Part one introduces the rain forest ecosystem and provides conceptual background material needed in the determination of problems, the…

Designed to address the major conceptual problems associated with evolution and variation and survival in populations, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…
