Sequence effects in solving knowledge-rich problems: The ambiguous role of surface similarities
Sequence effects are said to occur whenever the problem solving performance varies as a function of the order in which problems are solved. We present a framework that explain sequence effects as a result of (a) learning during solving a problem and of (b) transferring the learned content on succeeding problems. In two experiments we studied the ambiguous influence of surface similarities among structurally dissimilar knowledge-rich problems on sequence effects. These experiments demonstrate tha

The Atlas of Canada Web site is maintained by the governmental Natural Resources Canada Agency. This excellent interactive mapping and informational device lets users choose from dozens of topics to map such as geology, hydrology, land cover, glaciers, wetlands, natural hazards, and sea ice, as well as several others such as people and society, economic, health, and more. Once a map loads, users can zoom in and out, pan directions, get statistics about a point of interest, and get information fr
Towards Web 2.0 Schools: Rethinking the Teachers Professional Development
This paper aims at analyzing the Web 2.0 based distance education in the K-12 schools as an emerging phenomenon that catalyzes a new educational reform all over the world. Some pre-Web 2.0 best practice examples are analyzed in order to draw the main findings in the paper. The teacherÂ’s professional qualification designed to meet the new challenges is considered as a key problem for a successful penetration of this phenomenon in the schools. It is emphasized on the importance of designing a lif

Part of the National Center for Education Statistics' Classroom feature, Create a Graph is a simple, visual program in which kids can create a custom bar, area, line or pie graph. Clicking on the graph type from the menu leads to a brief overview about that type of graph, what sorts of data it is useful for, and links to the data entry page. On the data entry page, kids can enter up to 15 data values, type titles, select graph size and colors (12 to choose from), designate .png or .jpeg file typ

This issue of Topic in Depth explores some of the resources available online regarding school finance. The first article from the RAND Review (1) discusses the challenges involved in meeting the ambitious goals established by the No Child Left Behind (NCLB) Act and the need to develop a school accountability system that can provide "the incentives and resources that the schools really need to help all students meet the state performance standards." In the second article (2), Linda Darling-Hammon
Investigating human computer interaction issues in designing efficient virtual learning environments
Today, when an enormous number of computer-based systems exist, the human activities are being computer mediated. Usually, in designing the interface to those systems, the human-computer interaction is left behind without consideration. In this paper, a literature in human-computer interaction is to be reviewed and the technology aspect of human computer interaction is to be analyzed. Also, general design principles are to be reviewed. According to all these issues, recommendations to designing

Engaging in social issues in today's society requires an understanding of numerical data, statistics, and mathematical assumptions that underlie discussions about the federal budget, the spread of disease and other issues. However, the mathematics and the social issues are often considered in isolation and leave many Americans "ill-prepared to make informed decisions." The Thinking with Data Project is a new initiative of the National Science Foundation, SRI International, Kent State University

GeoVRML is an official Working Group of the Web3D Consortium (http://www.web3d.org/) and its goal is to develop tools and recommended practice for using the Virtual Reality Modeling Language (VRML) to represent geographical data. The idea is that geo-referenced data (maps and 3-D terrain models) can be viewed over the web using a standard VRML plugin. GeoVRML Working Group has a mailing list where discussions and developments are posted. Specifications, source code, examples, tools and the accom

Since the concept of permaculture was introduced by biogeographer Bill Mollison in the 1970s, it has attracted increasing interest from agriculturalists, designers, ecologists, and others. The Permaculture Research Institute (PRI) describes permaculture as "the harmonious integration of landscape and people providing their food, energy, shelter, and other material and non-material needs in a sustainable way. It is also the conscious design and maintenance of agriculturally productive ecosystems
ZAPs: Using interactive programs for learning psychology
ZAPs are short, self-contained computer programs that encourage students to experience psychological phenomena in a vivid, self-explanatory way, and that are meant to evoke enthousiasm about psychological topics. ZAPs were designed according to principles that originate from experiential and discovery learning theories. The interactive approach that is offered invites students to engage in subject matter through exploration, experience, and discovery of psychology. In an empirical study the effe
The Logic-ITA in the classroom: a medium scale experiment
This paper presents the experiment and consequent evaluation of introducing the Logic-ITA in a second year tertiary undergraduate class. The Logic-ITA is a web-based Intelligent Teaching Assistant system, aimed at alleviating some of the problems caused by large classes or distance learning. Its domain of application is the construction of formal proofs in logic. The system acts as an intermediary between teacher and students: on one hand, it provides students with an environment to practice for

CPM est alors construit sous la forme d'un profil UML.Il se positionne au niveau des phases de conception en amont des EML (Educational Modeling Language). Nous présentons alors une technique
An introduction to programming and the power of abstraction, using Abelson and Sussman's classic textbook of the same name. Key concepts include: building abstractions, computational processes, higher-order procedures, compound data, data abstractions, controlling interactions, generic operations, self-describing data, message passing, streams and infinite data structures, meta-linguistic abstraction, interpretation of programming languages, machine model, compilation, and embedded languages.
This course will provide a framework for recognizing and analyzing the major distinctive regions of the world in comparative context. The most important interrelations between environment, economy, ethnicity, and the national identity and viability of states will be explored.
