Children Know More than You Think: How Counting Represents What Children Must Learn
Dr. Barbara Sarnecka, Assistant Professor of Cognitive Sciences at the University of California, Irvine, studies the relationship between young children’s number word knowledge and how it predicts their performance on a numerical task without number words, i.e. What is the early meaning of counting “one”, “two,” and “three”? She has discovered that many children answer the question "how many" with the last word used in counting, despite not understanding how counting works. Only c
Planning, Policy and Design 139: Water Resource Policy Water is the economic, social, and physical lifeblood of humanity, providing the bases for agriculture, industry, transportation, energy production, and life itself. Despite its importance, alarming signs suggest that there are looming threats to this vital resource. The World Resources Institute contends that the world's thirst for water is likely to become one of the most pressing issues this century due to population growth, drought, and climate change.

What Does the Drooping Book Business Need? How About a Jolt of Espresso?
What if you could print a perfect-bound volume for as little time as it takes to brew a cup of coffee? That is the premise behind the Espresso book machine, which turns digital PDF files into paperbacks in minutes. Jason Epstein and Dane Neller, chairman and CEO respectively of On Demand Books in New York, the company behind the Espresso book machine, believe their technology has the potential to transform book publishing. Epstein, who was editorial director of Random House for 40 years, recentl
Examines health issues, scientific understanding of causes and possible future approaches to control the major environmental health problems in industrialized and developing countries.
Testing and Assessing Mathematical Skills by a Script Based System
Especially in the mathematical education there seems to be a need for strict drill and practice exercises. Such training cannot be met by traditional means. Therefore, a computer program is needed which generates parametrisable questions/problems which the students have to answer/solve and which at the same time assesses the answers/solutions of the students. We designed such a system as an interface between the learning platform ILIAS and MATLAB/Maple as the symbolic mathematics engine. We dem
Computer-based Metacognitive Training: Improving the Diagnostic Expertise of Novice Graduates
The diagnosis problem-solving task can be complex in many professions for which it is central, for example medical diagnosis, farm-management consultancy, etc. This is because often the expert must solve problems and make decisions in complex situations and while under time pressures. The complex nature of the problem situations and the novices lack of advanced metacognitive skills also make it difficult for novices to gain expertise and successfully solve problems in their fields. From the li
Informational technologies in resolving the social issues of school communities in Uzbekistan
This article examines the experience of 40 schools of Uzbekistan in usage of Informational technologies in resolving the social issues of their communities. The article describe the projects that were used by schools in the framework of the "Global Connections and Exchange - Uzbekistan" programme during the 2005-2007 academic years, and results of the projects and their positive experience.
Building Bridges within Learning Communities through Ontologies and "Thematic Objects"
Communication through artefacts, in the sense of objects (co-)constructed by learners, is a well known mechanism in synchronous shared workspace environments. In this article, we explore the potential of extending this principle to heterogeneous, anonymous and asynchronous learner communities by drawing on existing work, e.g. in the areas of "social navigation" and recommender systems. A new ingredient is the description and provision of "thematic objects" embedded in a task/activity context. De
Gemeinsame Wissenskonstruktion in computervermittelter Kommunikation: Welche Kooperationsskripts fö
Goal of this study is the facilitation of participation and knowledge acquisition in cooperative, computer-mediated learning environments. Two cooperative scripts with respect to discourse contents and interaction were developed to pre-structure communication. Both scripts were analyzed with respect to their influence on participation and application-oriented knowledge in computer-mediated learning environments. The factors "content-related cooperative script" and "interaction-related cooperativ
Anchored Interactive Learning Environments
Advances in computer technology and multi-media systems have led to widespread interest in computer-based instruction and learning environments. The use of video, animation, graphics, and simulation allow the presentation of material in realistic contexts, thus addressing the problems of inert knowledge while promoting constructive and generative learning. But the true potential and benefits of these systems are yet to be realized. Cognitive studies on learning and transfer suggest that concepts
From mirroring to guiding: A review of the state of art technology for supporting collaborative lear
We review systems that support the management of collaborative interaction, and propose a classification framework built on a simple model of coaching. Our framework distinguishes between mirroring systems, which display basic actions to collaborators, metacognitive tools, which represent the state of interaction via a set of key indicators, and coaching systems, which offer advice based on an interpretation of those indicators. The reviewed systems are further characterized by the type of inter
Mechanisms of common ground in case-based web-discussions in teacher education
Previous studies suggest that before the participants in Web-based conferencing can reach deeper level interaction and learning, they have to gain an adequate level of common ground in terms of shared mutual understanding, knowledge, beliefs, assumptions, and presuppositions (Clark & Schaefer, 1989; Dillenbourg, 1999). In this paper, the main purpose is to explore how participants establish and maintain common ground in order to reach deeper level interaction in case-based Web-discussions. The s

A Logo-based Task for Arithmetical Activity
Young children attend to answer-getting readings of arithmetical notation. This is evidenced by many childrens exclusive acceptance of a + b = c syntaxes that lend themselves to computational readings (e.g. Behr et al., 1976; Carpenter & Levi, 2000; Knuth, Stephens, McNeil & Alibali 2006). Even those children who do accept a wider variety of syntaxes, such as a + b = b + a and c = a + b , adhere to a computational view involving getting answers to both sides of the equals sign and checking the
