Teachers at all levels are encouraged to use role-playing and simulation. Unfortunately, teachers usually overestimate role-playing's learning value and often ascribe too much power to simple simulation activities. Teachers use these methods mainly to change behavior (and values), not reinforce curriculum content. Sociodramas (scenes based on…

Although teachers at all levels are encouraged to use role-playing and simulation, they usually overestimate role-playing's learning value. Teachers use these methods mainly to change behavior (and values), not reinforce curriculum content. Sociodramas (scenes based on typical situations facing children) are more effective role-playing activities…

Much research comparing public and private schools infers that private schools' superiority is trivial, misleading, and results from skimming the best students. This article describes nontrivial private school advantages, such as a communitarian emphasis, greater influence on outside-class behavior, promotion of intergenerational bonding,…

Children of 2 different age groups (11-12, n=246; and 13-14, n=196) were asked to draw and write about dissolving in 2 different ways. Greater percentage of children at both ages gave accurate particle interpretation that accurate view of observable process. Consistency between two ways of looking at dissolving was not found to improve with age.…

Changes in children's understanding of experimentation are examined. Sixteen fifth and sixth graders worked on two experimentation problems consistent with an engineering and science model, respectively. The science model was associated with broader exploration, more selectiveness about evidence interpreted, and greater attention to establishing…

This study questions the effectiveness of a traditional teaching-by-example technique when used with students who hold misconceptions. Interview techniques were used to explore students' (n=21) responses to two different uses of examples and to provide indications of student reasoning. Results indicate that when students hold a misconception,…

Ideas and scientific definitions as reported by 9-12 year olds collected from class discussions, essays, or examination papers over the course of 32 years are presented. Topics include the living body, tracts, metabolism, the senses, the skeleton, the heart, respiratory ailments, genetics, microbiology, and modern medicine. (KR)

Criticizes an article by Browning and Lehman (1988) for (1) using "gene" instead of allele, (2) misusing the word "misconception," and (3) the possible influences of the computer environment on the results of the study. (PR)

Authors respond to criticisms by Smith in the same issue and defend their use of the term "gene" and "misconception." Authors indicate that they did not believe that the use of computers significantly skewed their data concerning student errors. (PR)

Examines teacher empowerment as it appears in current educational reform by analyzing the concept against a template of democratic assumptions and conditions. Analyzes empowerment's meaning and workplace requirements and provides a democratic rationale for the existence of public education. Academic achievement is not the sole purpose of…

The forward force of water on a hose is calculated using only the pressure gradient, the radius and length of the hose. The misconception about recoil on the nozzle is discussed. Dissipation energy and the consequent heat generation in a fluid flow are also described. (KR)

Presented are the results of a study of high school and college students concerning their thinking about functions of the human body. It was shown that students' thinking could be positively changed over the short term from teleologic to mechanistic. Sample survey questions are included. (CW)

The confusion by students on the use of three terms in their writing is discussed. The definitions of catabolite repression, constitutive, and ribosome binding site, given in the glossaries of 10 textbooks, are compared with the use of these terms in students' papers. (KR)

Describes the nineteenth-century parlor trick entitled the Fluttering Heart phenomenon which uses a red heart on a bright blue background. Discusses theories concerning the apparent fluttering. Suggests doing the trick with a red light-emitting diode in a darkened room. (MVL)

Describes a study to determine which action potential concepts are found in high school biology textbooks, find out how these concepts are presented, and identify misconceptions about the concepts. (PR)
