This study focused on misconceptions related to light and vision. Researchers administered diagnostic tests about light, vision, and color before and after instruction to 227 fifth-grade students over a 2-year period. They also conducted 11 clinical interviews. The tests and interviews revealed that almost all students shared certain…

This paper describes an exploratory study of conceptual change in 91 students enrolled in an introductory course at Michigan State University designed to help beginning teacher education students examine critically their preconceptions. The data consist of essay responses written at the beginning and end of the term. The authors were interested in…

Reviewed are findings on misconceptions in mechanics and their instructional implications. Many misconceptions are widespread and resistant to change but students have useful intuitions and reasoning processes that could be used more fully. One strategy for dealing with misconceptions is described. It stresses anchoring intuitions, analogical…

Described is a computer tutor designed to help students gain a qualitative understanding of important physics concepts. The tutor simulates a teaching strategy called "bridging analogies" that previous research has demonstrated to be successful in one-on-one tutoring and written explanation studies. The strategy is designed to remedy…

This paper reports an interview case study with two physics doctoral students designed to explore their conceptions about the theory of evolution. Analysis of interview transcripts reveals that both students mistakenly constructed a "theory of evolution by environmentally driven adaptation" instead of the commonly accepted "theory…

Presents baseline data about the existing state of elementary school teachers knowledge of physical science. A teacher questionnaire and physical science test were administered to participants (N=333) of a physical science inservice training program in Arizona. Results revealed inadequacies in teachers' knowledge of physical science and the…

Twelve linear algebra students were interviewed about the concept of a Solution of a System of Equations. The interviews were analyzed using APOS tools, in particular the ideas of Action, Process, Object and Schema, and Genetic Decomposition. The analysis of the interviews revealed several misconceptions of Solution. The analysis also revealed…

A longitudinal case study focused on the process of conceptual change in science of a young girl. The subject, the researcher's granddaughter, was 6 years and 6 months old and in first grade when the first of 19 hour-long sessions began. Sessions were spread over a two-year period. A concurrent case study was being conducted with the researcher's…

The study of chemistry includes many abstract concepts that students may find difficult to understand. A fundamental yet troublesome part of introductory chemistry courses is the topic of electron configuration and specifically quantum-mechanical orbitals. In an effort to examine the way students internalize the concept of atomic orbitals and how…

The purpose of this study is to examine one possible source of misconceptions that are held by students of genetics--the teachers. Is there evidence to suggest that prospective biology teachers might have misconceptions about genetics and related concepts? If prospective biology teachers have misconceptions in genetics, how do these misconceptions…

There is rarely a perception in colleges and universities that everyone owns the financial plan. Deans, department chairs, and division heads are most concerned with their own budgets, rather than the aggregate. Mythologies about how the academic and financial sides of the house operate create artificial divisions and compromise the development of…

Although most teachers are aware of documents identifying standards in their subject areas, few know about "external" standards documents or the standards movement as a whole. Despite impressive lists of content standards, U.S. educators lack direction due to four major problems: multiple documents, too much information, controversial content, and…

Aims to quantify the models that 13- and 14 year-old students hold about the causes of the greenhouse effect and ozone layer depletion. Assesses the prevalence of those ideas that link the two phenomena. Twice as many students think that holes in the ozone layer cause the greenhouse effect than think the greenhouse effect causes ozone depletion.…

Argues that current testing of student understanding provides insufficient information to a researcher investigating strategies for changing students' explanatory ideas. Outlines a new test based on recent work in child development. (DDR)

Clifford Stoll's skeptical look at the computer mania besetting education raises issues about computerization and networking costs, the relationship between accessing information and becoming educated, and the role of human interaction in learning. By placing the computer before the curriculum, are proponents providing the best education possible…
