This research was conducted to examine the conditions under which learner-generated illustrations serve as an instructional strategy promoting conceptual change. Specifically, the nature of students' misconceptions and the effects of student-generated descriptive drawings on conceptual understanding of scientific principles associated with the law…

This study examined university engineering and physical science students' misconceptions of the nature of magnetic field. It is assumed that a significant knowledge of the sources of magnetic field is a basic prerequisite when students have to think about electromagnetic phenomena. To analyze students' conceptions, we have taken into account the…

This study focuses on the conceptions of trainee, primary, and subject teachers about three phenomena: the motion of objects, seasonal changes, and aggregate changes of matter. A total of 198 participants completed a questionnaire concerning two types of tasks. First, teachers evaluated the adequacy of a given explanation as compared to their…

Very little information exists about children's prior knowledge and thinking (including misconceptions) about transportation, a topic commonly taught in elementary social studies. To develop such information, individual interviews were conducted with 96 K-3 students, stratified according to grade level, achievement level, and gender. The students…

The present study investigated 90 elementary teachers' ability to identify two systematic error patterns in subtraction and then prescribe an instructional focus. Presented with two sets of 20 completed subtraction problems comprised of basic facts, computation, and word problems representative of two students' math performance, participants were…

The road to Brown v. Board of Education (1954) was a slow and circuitous climb, whereas the retreat down from Brown has been swift and direct. This article reviews 4 distinct U.S. Supreme Court eras of racial decisions: the segregation, preparatory, desegregation, and resegregation eras. It notes both the strengths and weaknesses of Brown and…

The Knowledge about Attention Deficit Disorder Questionnaire (KADD-Q) was administered to 256 teachers and 92 parents. Statistical analysis revealed the KADD-Q to be an internally consistent measure of teachers' and parents' knowledge of ADHD. Findings demonstrated that the levels of teachers' and parents' knowledge about the causes of ADHD was…

Almost 25 years ago, Bourdieu and Passeron (1977) explained how educational systems foster a "misrecognition" of the part that schools play in social reproduction. They noted that it is to the advantage of the dominant elements of society and educators themselves to perpetuate a strong belief in the legitimacy of schools as institutions that…

In 2001 foot and mouth disease broke out in the UK and millions of farm animals were slaughtered in order to eradicate it. This affected farmers, town dwellers, adults and children. Based on a small sample of 56 e-mails to a children's BBC (CBBC) message board and using an ethnomethodological approach, this article explores the way in which…

This study investigates the role of cultural beliefs and practices in teaching. The focus is the process of socialization by which students learn to deal with mistakes. Analyzed are teacher-student interactions surrounding mistakes videotaped in 30 Italian and 30 U.S. eighth-grade mathematics lessons. These are complemented by interviews with…

The purpose of this study was to investigate the effect of conceptual change texts accompanied with concept mapping instruction, compared to traditional instruction (TI), on 8th grade students' understanding of solution concepts and their attitudes toward science as a school subject. Solution Concept Test was developed as a result of examination…

The results of a large scale (N=1001) cross-sectional (Years 6, 8 and 10) study of students' ideas about the composition of unpolluted air, the nature of air pollution, the biological consequences of air pollution, and about acid rain and the Greenhouse Effect are reported. A range of persistent alternative conceptions were identified, in some…

Little is known about researchers' understanding of confidence intervals (CIs) and standard error (SE) bars. Authors of journal articles in psychology, behavioral neuroscience, and medicine were invited to visit a Web site where they adjusted a figure until they judged 2 means, with error bars, to be just statistically significantly different (p…

Adults widely misunderstand youth. Although this is not a new phenomenon--adults have been baffled by teenagers for centuries--a rapidly changing media environment coupled with the increasing demands placed on the youth have fueled the growing generation divide in unprecedented ways. Indeed the modern, fast-paced, multi-tasked, highly mobile,…

False memories are often demonstrated using the misinformation paradigm, in which a person's recollection of a witnessed event is altered after exposure to misinformation about the event. The neural basis of this phenomenon, however, remains unknown. The authors used fMRI to investigate encoding processes during the viewing of an event and…
