Randomly selected high school seniors (n=32) were interviewed to assess their understanding of the nature of science. Views held by 10% or more of the students are reported in the categories of general views, scientific facts, scientific theories, and scientific laws. Reports how students differentiate between scientific facts, laws, and theories.…

Presents examples of physics as applied to the sport of skiing. Examples examine the physics of sliding, unweighting, ski turning, wind resistance, the parabolic and circular motion of aerial skiers, and the aerial maneuvers of ski jumpers. (MDH)

Describes the design of the superconducting bird, a device to demonstrate the phenomenon of superconductivity. Discusses the utilization of the device as an example of a motor and compares it to the toy called the drinking bird. (MDH)

In this article, constructivism is examined as an epistemological basis for school science and mathematics instruction. The nature and process of constructing scientific and mathematical knowledge in school settings is also considered. A distinction is made between truth and feasibility, and the implications for science education are discussed.…

Describes an intensive 2-week Operation Physics Institute at Western Washington University for 67 elementary and middle school teachers designed to improve science instruction. Presented several discrepant events in physics; teachers explained the events with scientific methods with the aid of concept lists. (KS)

The effects of students' misconceptions, declarative knowledge, and stimulus conditions on students' solutions to a problem in basic electricity were studied for 80 undergraduates at Iowa State University (Ames). The implications of the findings of influence by knowledge and stimulus conditions are discussed. (SLD)

This article looks at the historical interpretations and counterinterpretations of some experiments selected from science history. The homocentric spheres of Eudoxus, hermetic and scientific concepts of the universe in the middle ages, and the change in the concept of the world are included. (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…

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…

Describes the use of observation folders as a tool for understanding and refining the basic skills of observation and inference that are important to the young child. These folders provide opportunities for students to view and examine "mystery pictures," make inferences, and arrive at their own conclusions about the subject of the…

The effects of conceptual change text and application questions in 139 college students' learning of electricity concepts were investigated. The experiment was a 2X2X2X2 factorial. Compared to traditional text and no questions, conceptual change text and application questions, respectively, improved acquisition of qualitative concepts.…

Discussed are teaching methods that can be used in association with amusement park rides. The basic principles behind the effects of several rides are reviewed and illustrated. (CW)

Described is an interdisciplinary unit on pseudoscience which combines interest in unidentified flying objects (UFO's), physics, astronomy, art, and english composition. The different phases of the lesson, assignments, and evaluation are discussed. A list of books available on UFOs is provided. (CW)
