Political Rhetoric or Policy Reality? Tracking Trends in Environment, Peace, and Security

Geoffrey D. Dabelko, PhD, Director, Environmental Change and Security Program, Woodrow Wilson Center for Scholars (Washington DC)

Political Rhetoric or Policy Reality? Tracking Trends in Environment, Peace, and Security: Over the past 25 plus years, the understanding of environment and security links has evolved to reflect changing threat and opportunity scenarios. Today, "environmental security" has become a popular phrase used to encompass everything from oil exploration to

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

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.

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

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 children’s 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

Like the road map in your atlas, this mapping activity will help students visualize the layout of the text before they start reading so they will have an idea of where they are going (or where to find the information they are looking for) when they start reading.
