Institute For Dynamic Educational Advancement
The Institute for Dynamic Educational Advancement (IDEA.org) is a U.S.-based nonprofit organization working in the area of scientific and cultural literacy. The organization was established in 1998 and incorporated in 2002, and has collaborated with museums, schools, nonprofit organizations, and public service projects. Activities * WebExhibits "virtual museum" – in 1999, IDEA founded the WebExhibits virtual museum, an interactive, virtual museum of science, humanities, and culture that uses information, virtual experiments, and hands-on activities that prompt visitors to think, to formulate questions, and to explore topics from a variety of angles. IDEA published research on exhibit design and usability, and advocated for the format as an effective approach to draw in visitors to complex, multidisciplinary topics. * SpicyNodes - is a presentation method for visually browsing hierarchical information, similar to concept mapping. Several implementations of SpicyNodes have been d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockville, MD
Rockville is a city that serves as the county seat of Montgomery County, Maryland, and is part of the Baltimore–Washington metropolitan area. The 2020 census tabulated Rockville's population at 67,117, making it the fifth-largest community in Montgomery County. Rockville, along with neighboring Gaithersburg and Bethesda, is at the core of the Interstate 270 Technology Corridor which is home to numerous software and biotechnology companies as well as several federal government institutions. The city, one of the major retail hubs in Montgomery County, also has several upscale regional shopping centers. History Early history Situated in the Piedmont region and crossed by three creeks ( Rock Creek, Cabin John Creek, and Watts Branch), Rockville provided an excellent refuge for semi-nomadic Native Americans as early as 8000 BC. By the first millennium BC, a few of these groups had settled down into year-round agricultural communities that exploited the native flora, includin ...

WikiNodes
WikiNodes is an app for the Apple Inc., Apple iPad built by Institute for Dynamic Educational Advancement, IDEA.org. WikiNodes was the first tablet app for browsing Wikipedia using a radial tree approach to visualize how articles and subsections of articles are interrelated. The app displays related items (articles or sections of an article), which spread on the screen, as a spiderweb of icons. Operation The app uses the SpicyNodes visualization technique which was awarded a "best for teaching and learning" award in 2011 from American Association of School Librarians, American Association of School Librarians (AASL), and voted #edchat's 35 Best Web 2.0 Classroom Tools in 2010. The user interface is based on two display modes: * Page view – displays Wikipedia articles in long form, similar to how they appear on the main Wikipedia web site. * Node view – divides Wikipedia articles into sections, and links articles to related articles, similar to mind mapping. The user can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Educational Research
Educational research refers to the systematic collection and analysis of data related to the field of education. Research may involve a variety of methods and various aspects of education including student learning, teaching methods, teacher training, and classroom dynamics. Educational researchers generally agree that research should be rigorous and systematic. However, there is less agreement about specific standards, criteria and research procedures. As a result, the value and quality of educational research has been questioned. Educational researchers may draw upon a variety of disciplines including psychology, economics, sociology, anthropology, and philosophy. Methods may be drawn from a range of disciplines. Conclusions drawn from an individual research study may be limited by the characteristics of the participants who were studied and the conditions under which the study was conducted. General characteristics Gary Anderson outlined ten aspects of educational research: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-profit Organizations Based In Maryland
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworthiness, honesty, and openness to eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Museum
A virtual museum is a digital entity that draws on the characteristics of a museum, in order to complement, enhance, or augment the museum experience through personalization, interactivity, and richness of content. Virtual museums can perform as the digital footprint of a physical museum, or can act independently, while maintaining the authoritative status as bestowed by the International Council of Museums (ICOM) in its definition of a museum. In tandem with the ICOM mission of a physical museum, the virtual museum is also committed to public access; to both the knowledge systems imbedded in the collections and the systematic, and coherent organization of their display, as well as to their long-term preservation. As with a traditional museum, a virtual museum can be designed around specific objects (such as an art museum or a natural history museum), or can consist of online exhibitions created from primary or secondary resources (as, for example in a science museum). Moreover, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Tree
A radial tree, or radial map, is a method of displaying a tree structure (e.g., a tree data structure) in a way that expands outwards, radially. It is one of many ways to visually display a tree, with examples extending back to the early 20th century. In use, it is a type of information graphic. Basic layout The overall distance "d" is the distance between levels of the graph. It is chosen so that the overall layout will fit within a screen. Layouts are generated by working outward from the center, root. The first level is a special case because all the nodes have the same parent. The nodes for level 1 can be distributed evenly, or weighted depending on the number of children they have. For subsequent levels, the children are positioned within sectors of the remaining space, so that child nodes of one parent do not overlap with others. There are many extensions to this algorithm to create more visually balanced layouts, to allow a user to navigate from node to node (chang ...

Color Space
A color space is a specific organization of colors. In combination with color profiling supported by various physical devices, it supports reproducible representations of colorwhether such representation entails an analog or a digital representation. A color space may be arbitrary, i.e. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names (including discrete numbers infor examplethe Pantone collection), or structured with mathematical rigor (as with the NCS System, Adobe RGB and sRGB). A "color space" is a useful conceptual tool for understanding the color capabilities of a particular device or digital file. When trying to reproduce color on another device, color spaces can show whether shadow/highlight detail and color saturation can be retained, and by how much either will be compromised. A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. tr ...

Color Vision
Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different wavelengths (i.e., different spectral power distributions) independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons and then ultimately to the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of evolution in different animal taxa. In primates, color vision may have evolved under selective pressure for a variety of visual tasks including the foraging for nutritious young leaves, ripe fruit, and flowers, as well as detecting predator camouflage and emotional states in other pr ...

Wikipedia Signpost/2011-06-13/In The News
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations. Wikipedia was launched by Jimmy Wales and Larry Sanger on January 15, 2001. Sanger coined its name as a blend of ''wiki'' and ''encyclopedia''. Wales was influenced by the "spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton. Initially available only in English, versions in other languages were quickly developed. Its combined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
