Designed to address conceptual problems associated with ecology, this module can be used with high school students or college nonscience majors including those in elementary education. The materials offer guidance to teachers in diagnosing student deficiencies, in creating dissatisfaction with misconceptions, and in providing opportunities for…

Designed to address the major conceptual problems associated with respiration and photosynthesis, 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' Science Courses. The…

This paper describes the BUD project which surveyed childrens' conceptions of division, and of fractions and decimals. The lack of connection between counting skills and conceptual understanding is discussed. The expectations for new algorithms and the basic idea in planning the BUD project are summarized. Some previous studies on counting, the…

Reports on a study which tested eight categories of logical fallacies with secondary students, student teachers, and teachers from Australia, South Africa, and Israel. Results indicate that logical fallacies were exhibited by all the groups. Implications are discussed. (ML)

Discusses three current approaches to curriculum for science education which seem to be converging on a similar model for instruction: technology and society; misconceptions in science; and hands on science. The technologies required for the implementation of this teaching model are identified, and appropriate science education resources are…

Refutes the view that two capacitors in series with a source of constant voltage carry identical charges. Provides experimental procedures to verify this claim. (YP)

Compares the effectiveness of two instructional models in bringing about a valid understanding of science concepts in prospective elementary teachers. Describes the two instructional models; an expository model and a learning cycle model. Concludes that college students understandings of science concepts may be improved using a combination of the…

Discusses electricity's documented effects on the human body, including both the dangers to human health and the medical application of electrical stimulation to heart problems. Discusses the teaching of such physics topics to potential medical students. (TW)

Describes a cooperative program between Indiana University and The Children's Museum of Indianapolis that was designed to expose preservice elementary teacher trainees to children who were interacting with the museum's displays. Discusses some of the misconceptions that the children held about certain scientific concepts and the entertainment…

Describes a study in which paradoxes about seasons, hemispheres, and altitude were used to teach concepts in climatology. The misconceptions commonly held about the earth-sun distance relationship were used as an instructional strategy with an experimental group, which outgained the control group on an achievement test. (TW)

Discusses how to address the concept of chemical equilibrium through the use of thermodynamic activities. Describes the advantages of setting up an equilibrium constant in terms of activities and demonstrates how to approximate those activities by practical measures such as partial pressures, mole fractions, and molar concentrations. (TW)

The knowledge that students bring to the classroom has been a well-studied domain. The types of knowledge studied have included content knowledge as well as epistemological beliefs that students hold. This study focuses specifically on preservice elementary education students' understanding of science and science learning as a meaning-making…

This paper reports on a study that used Hestenes' Force Concept Inventory (FCI) to describe Newtonian force concepts and misconception belief systems held by preservice teachers in physical science and physics students attending an urban university in Chicago, Illinois. Results indicate that constructivist instruction in force concepts was of…

This paper reports data collected during the first year of the Understandings of Consequence Project. This project explores how mismatched models of causality, instances when students' assumptions about how causes and effects behave significantly depart from scientific ones, may generate and/or exacerbate difficulties in achieving scientific…

America's corporate executives consider a huge world-class workforce superfluous. Corporate restructuring's bottom line was the massive shedding of workers, a reduction in future job opportunities, and a concomitant plunge in income, benefits, and living standards for millions. Experts predict that only 20% of well-trained college graduates will…
