In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (CW)

A visual model of fractions, the tower of bars, is used to discover patterns. Examples include equalities, inequalities, sums of unit fractions, sums of differences, symmetry, and differences and products. Infinite sequences of numbers, infinite series, and concepts of limits can be introduced. (DC)

The article discusses the classic problem: "Given an equilateral triangle and a point P inside the triangle, what is the sum of the distances from P to the three sides?" The problem is used to illustrate the generative nature of problem-posing using the heuristic "What happens if...?" (PK)

Examines the role of the outdoors in child development. The expanse of outdoors teaches humility, yet does not judge, thereby teaching self-esteem. Nature's diversity teaches that difference is the norm, thereby teaching tolerance. Small nearby places that children favor--trees, brooks, ponds--nurture a sense of home. Early outdoor experiences are…

Reviews the objectives of laboratory work in chemistry education, current laboratory practice, and factors likely to impact on the nature of laboratory work in the future. Proposes that more investigation-style laboratory work be provided in order to foster the development of students' investigation skills. (Author/MKR)

Addresses two issues confronting teachers who use theme immersion in their classrooms: integration of content through theme, and inquiry-based curriculum. Discusses the challenge and justification for each issue. Notes that inquiry teaching means constantly searching for better ways to support children' s own inquiry processes. (BAC)

Proposes the use of conceptualization, exploration, and higher-level problem solving in differential equations courses as a replacement for some of the traditional material that can now be delegated to the computer. (MKR)

Describes the use of small sandboxes with toy figures as an activity that helps children cope with the emotional upheaval in their lives. (HTH)

Constructivism, which holds that knowledge is created out of each individual's own experience, is recapturing researchers' attention. To constructivists, teachers are not omniscient oracles, but nutritionists providing an environment for children to grow their own knowledge. Students might learn division by planning a field trip instead of…

This study focused on students' development of inquiry skills in a computerized learning environment. Seven Year-11 classes (n=120) interacted with a computerized database, "Birds of Antarctica," and curriculum materials while the teacher used an inquiry approach to learning. Students perceived their classes as more investigative and…

Gives an example of an open exploration using trigonometric relationships in which the law of cosines can be deduced from the law of sines. Discusses the characteristics and value of the exploration process. (MDH)

Computational environments that provide integrated numeric, symbolic, and graphical capabilities provide new opportunities for laboratories in Numerical Analysis. Hermite interpolation is one topic that can benefit from such an environment. Describes a laboratory session using Mathematica that allows students to actively experience Hermite…

An open-ended data-analysis activity, prompted by a Royal Mail advertisement, explores the claim that the real cost of first class postage has fallen below the inflation rate. The activity provides realistic exercises in both arithmetic and statistical indices, and in logical interpretation of, and deduction from, the data. (JJK)

Reexamines basic aspects of creativity enumerated by Viktor Lowenfeld and shows how goals of art education have varied with time and social needs. Argues that interdisciplinary approach to learning, which involves seeing connections and realizing that all knowledge is one and whole, is what education is all about. Concludes that such approach was…

Presents the game "Life91," an adaptation of Conway's "The Game of Life." Played on a hexagonal board, the game generates number patterns of population size by rules that determine cell growth and death from one generation to another. An example illustrates the process. (MDH)
