A study of the processes by which 24 grade-12 Australian physics students brought order to their observations and practices shows that the phenomena students construct from their laboratory work (not always accurate) develop from connections among the embodied practices of language and physical action, their world, and social relations. (SLD)

Considers the relevance of the points raised in the preceding articles in this issue to the sociolinguistic development of children with speech and language impairments. Notes that such children often have low self-esteem and that their inability to negotiate an identity for themselves through discussion with their peers may contribute to this…

Reports a study that tracks the changes in children's ideas about science and scientific concepts through the use of interviews and questionnaires. Students respond to seven questions about science learning, scientists, and their future relationship to science. (DDR)

Describes a study that investigates the relationship between secondary students' written responses and the mathematical and cognitive processing used when solving a complex problem. Contains 40 references. (DDR)

Preservice elementary school teachers in Israel (n=608) answered questions about energy concepts. Results revealed the following: (1) many hold alternative conceptual frameworks, not accepted scientific concepts; (2) many do not accept the idea of energy conservation or degradation; (3) they confuse energy and force; and (4) they have an ambiguous…

Demonstrates how mathematics is a changing science through an in-depth look at the history of the development of logarithms. Serves as a reminder to continue to remember and appreciate the efforts and contributions of past mathematicians. (KHR)

Reports on a study that examines how well middle school programs support the attainment of key scientific ideas specified in the national science standards. Identifies the typical strengths and weaknesses of these programs using research-based criteria. (Contains 88 references.) (DDR)

Focuses on the role of Thought Experiments (TEs) in ongoing processes of conceptual refinement for physicists and physics learners. Analyze TEs related to stellar evolution and general relativity. Identifies the stages at which crucial errors are made in these TEs and the cognitive processes which lead to these errors. Discusses implications for…

Presents a teaching approach related to the concept of function that lead students working within a graphic milieu to producing, discussing, and testing the validity of mathematical statements and theorems. Indicates that students experimenting with the approach became able to think of functions as objects and engage in questions of the validity…

Develops an instrument for measuring secondary students' cognitive conflict levels as they learn science. Indicates that cognitive conflict consists of four constructs: (1) recognition of an anomalous situation; (2) interest; (3) anxiety; and (4) cognitive reappraisal of the conflict situation. Discusses implications for instruction and…

Reviews five methods of representing cognitive structures: (1) free word association; (2) controlled word association; (3) tree construction; (4) concept map; and (5) flow map. Discusses the applications as well as the limitations of these methods by comparing the types of analysis that are generated. (Contains 37 references.) (Author/YDS)

Explores how to use Gardner's Multiple Intelligence theory to help students' master multiplication. Focuses on helping children use their different intelligence strength to attain conceptual understanding of multiplication, develop their own thinking strategies for harder facts, and build mastery through practice and problem solving. (KHR)

Describes an action research project aiming to improve student understanding of decimal numbers through an instrument. (YDS)

Discusses using and producing poems as a way of clarifying and accessing children's ideas about science topics. (Author/MM)

Introduces a new way of evaluating instructional strategies using computers. Discusses two basic theories, instructivism and constructivism, in terms of their effectiveness in conceptual learning. Outlines the radical forms of constructivism. Introduces and evaluates two versions of a multimedia physics software based on the inventive model and…
