This article describes how research on children's geometric thinking was used in conjunction with the picture book "The Greedy Triangle" to gain valuable insights into children's prior geometric knowledge of polygons. Exercises focused on the names, visual appearance, and properties of polygons, as well as real-world connections for each, are…

Speakers routinely gesture with their hands when they talk, and those gestures often convey information not found anywhere in their speech. This information is typically not consciously accessible, yet it provides an early sign that the speaker is ready to learn a particular task (S. Goldin-Meadow, 2003). In this sense, the unwitting gestures that…

Two experiments using the "projection of shadows" paradigm investigated multidimensional reasoning, implicit and explicit knowledge, and the nonlinearity concept in 5-, 9-, and 13-year-olds and adults. Participants estimated the resulting shadow lengths of differently sized objects, placed at varying distances from a light source. Experiment 1…

In order to think, to interpret and judge correctly, the humans have to comprehend what they have learned. Concepts are the abstract representatives of the classifications that are formed by objects, events, ideas and behaviors which have common specifications. (Fidan, N., 1985). Concepts reduce the complexity by simplifying the environment that…

Using elementary school pupils as an example, the author distinguishes between equal and equivalent knowledge and shows how both relate to individualized learning situations applicable to continuing education. (AG)

A group of 20 6-year-old children were examined to find out their concept of "flower" and the amount of detailed knowledge they possessed about flowers. Data was collected on the techniques teachers use to introduce such information. (AJ)

Examines the underlying dimensionality of a nutrition knowledge test for preadolescent girls. In contrast to the manner in which nutrition knowledge has previously been measured in research, analysis of the results indicates that their nutrition knowledge is multidimensional. The dimensions include "differentiated eating" and…

Proposes that recent shifts in the representation of knowledge to a focus on practices and activities have profound implications for students' learning of mathematics. Discusses relationships between knowledge, practice, and identity in the mathematics classroom. (Author/MM)

Provides a conceptual framework for considering the distinction between evaluation use and evaluation influence and the relationship between evaluation use and knowledge use. Clarifies and expands some of the established definitions of concepts related to evaluation use. (SLD)

Studied "doing" numeracy in the workplace, analyzing a transcript of a workplace incident involving numeracy as a sales consultant took an order in a motel setting. Discusses ways numerical knowledge is involved in the calculation of rooms and beds available. (SLD)
