The results of an investigation concerned with sequential reasoning in interpreting the current flow in d.c. electric circuits are presented. Analysis of the results of a questionnaire completed by 236 college sophomores shows the presence of a common misunderstanding based on a "local" interpretation of the current flow. A copy of the…

A survey of adults that shows considerable misunderstanding of two major ideas--that there is no energy in fuels and burning involves two stages--is discussed. Proposed are fundamental changes in the way ideas about burning are introduced to children. (KR)

An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

The perspectives of preservice teachers in utilizing concept mapping as a learning strategy are examined. Preservice teachers were asked to construct concept maps, reflect on the process, and then to record their reactions in personal journals which became the primary data source. Reaction to preservice teachers concept maps and apparent learning…

Literacy should not be limited to decoding written text. More broadly construed, education should address the many ways in which experience is represented, the development of cognitive potential, and differences in intellectual proclivities. The object should be cultivation of a broad capacity to construct meaning. (SK)

The conceptual views of homeostasis held by students (n=300) in seventh grade life science, tenth grade biology, and college zoology were examined. A biographical questionnaire, the results from two Piagetian-like developmental tasks, and a concept evaluation statement of homeostasis were collected from each student. Understanding of the concept…

Investigates the contributions of tonal syllables, hand signs, and letter representations of tonal syllables to the development of verbal and symbolic tonal skills of first grade students. Finds no method to be significantly better than another. Concludes that tonal aptitude is the most significant predictor of tonal syllable and pitch…

Reviews "Soviet Studies in Mathematics Education: Volume 2. Types of Generalization in Instruction" (V. V. Davydov, National Council of Teachers of Mathematics, 1990), which is useful for educational researchers because its major theory of dialectical materialism offers a view of knowledge with a significant role for activities that…

An approach to teaching electrochemical driving force that helps students comprehend the forces that govern ion flux across biological membranes and sets the stage for more elaborate analysis of biochemical signals is presented. Background information and two sample problems and answers are included. (KR)

Based on a two-tiered epistemological model (preliminary physical concepts and emerging mathematical concepts), studied the construction of number among 91 kindergarten students in France, Canada, and the United States. Subjects' cognitive numerical structures were surprisingly similar despite differences in language and culture. (SV)

Because concept maps are designed to find out what the learner knows about a subject and are, in effect, maps of cognition, this article synthesizes relevant facts, concepts, and principles from cartography and applies them to concept mapping. The metaphor of the map and its applicability for representing scientific concepts are discussed. (PR)

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…

A study (n=631) of children's ideas on motion of objects is reported. On three items of a four-part questionnaire, responses changed as the children matured, passing through distinct, successive stages with respect to their conceptual understanding. If teaching strategies to overcome misconceptions are to be effective, they must be appropriate to…

Presents activities that utilize balloons to encourage students to explore questions related to scientific concepts. Concepts explored include light, heat, charged ions, polarization, and the sense of smell. (MDH)
