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…

Explores self-reflection skills and views in the context of an introductory physics course for first-year engineering honors students. Measures students' conceptual learning gains using standard survey instruments. Finds that students with high conceptual gains tend to show reflection on learning that is more articulate and epistemologically…

Describes a framework for examining mathematical discourse and shows how to apply this framework to appreciate the complex relationship between discourse and understanding in mathematics. Focuses on the role of discourse and the different types that emerge as students solve a particular task. (KHR)

Uses student-constructed models to teach about the atom and its structure in order to achieve internalized understanding of the concept among students. (YDS)
