Models the ideas of children's misconceptions and subsequent acceptance of conventional scientific thought on the simple cusp of catastrophe theory. Demonstrates one theory of the forces which are necessary to change a misconception to a scientific concept. (CW)

The research reported in this study was done to evaluate the understandings developed by students who meet science concepts through a textbook. Findings indicated that concrete concepts were better understood by eighth grade students than formal concepts and that students achieved some understanding of some formal concepts. (CW)

Presents an examination of the buoyancy principle which can serve as a simple but rigorous illustration of a falsification test that not only clears up a possible misconception but also points the way to a number of practical uses of buoyancy measurements that have not generally been recognized. (MVL)

Describes an interdisciplinary approach to science learning in settings usually associated with the humanities or social sciences. Explains the program, its rewards and results, the self and identity seminar, why the program works, and ways of adapting the program. (RT)

Presents results of a study examining how introductory economics students use graphic analysis. Concludes that the difficulties students have in analyzing an economic problem graphically result from problems with concept formation. Suggests that videotaping can assist instructors to understand and anticipate the learning processes that students…

Discussed is the idea that students come into their lessons with already preformed notions for many basic astronomical events. Examples of students' responses during an astronomy lesson are included. Suggestions for uncovering students' alternative frameworks are presented. (KR)

Durer's method for drawing an ellipse is used to explain why some people think an ellipse is egg shaped and to show how this method can be used to derive the Cartesian form of the ellipse. Historical background and suggestions for further reading are included. (KR)

Presents a first day physics activity having students determine the fine for a speeding ticket if the speeds considered include the earth's rotation and revolution speed, and the movement through the galaxy. (MDH)

Demonstrations to help students change their misconceptions about chemical bond breaking are presented. Students' misconceptions about chemical bonds in both biological and chemical systems are discussed. A calculation for the release of energy from respiration is presented. (KR)

Presents examples of evaluation studies of visitor interactions with science museum exhibits. Example one involves application of existing findings about naive notions of motion to task of engineering a novel encounter with parabolic trajectories. Example two is a student project evaluating a prototype exhibit on light pipes and concludes that…

Argues that science students often perceive physical events, the nature of scientific knowledge, and the nature of learning processes in different ways from science teachers and scientists, and that science teachers need to account for these differences in planning their science teaching. Contains 40 references. (WRM)

Proposes that instruction targeted at conceptual change should be designed to consider cognitive development and capitalize on what is known about social development. Examines instructional strategies (Concept Oriented Reading Instruction, Discussion Webs, collaborative writing, learning logs, and divided page journals) that promote middle school…

Assesses students' learning of evolution by natural selection within four different sections of an introductory biology course where each section used a different combination of curricular materials and instruction. Reports that comparisons between sections support the use of paired problem-solving instructional strategy in conjunction with the…

Presents the results of a study of elementary science teaching methods. Finds that teachers participating in the study always elicit children's ideas prior to science instruction, and thus consider student ideas to be important. Also finds that students perceived that their ideas were important whether or not the teachers addressed those ideas in…

The reform documents of the 1990s stressed that science is not practiced by a rigid scientific method, but science texts continue to describe the process as if it were rigid and linear. The purpose of this investigation was twofold: (a) to explore middle school in-service teachers' perceptions of scientific methodology and (b) to explore ways in…
