Presents a concept map that is a graphic referential tool, useful not only in the ordering of the reference material of a given domain, but also as a tool where the merging of verbal and graphic representation can have an advantage over the conventional linear structure of texts. (Author/VWL)

Discusses extand paradigms (ISBN, ISSN, ISMN, and the emerging ISAN). Models a procedure for assigning ISONs (International Standard Object Number) to objects and their surrogates. Describes resources requisite to the construction of the ISON, and outlines the necessarily cooperative work ahead if an ISON is to become a standard for visual…

This article describes the development of the video bookmark, hereinafter referred to as the videomark, and its application to the collaborative indexing of the lecture video in video-based distance education system. The combination of the videomark system with the bulletin board system (BBS), which is another network tool used for discussion, is…

This study examined the role of visual imagery in the centripetal execution principle (CEP), a graphic rule that is related to the drawing of complex figures that are composed of embedded geometric shapes. Sighted blindfolded children and children with early-onset low vision and early-onset blindness copied raised-line drawings (using only the…

The authors teach an astronomy unit in their seventh-grade course that they find never fails to motivate and stretch the imagination. The questions students ask are wonder-full: "What was here before the universe?" "If there was nothing before the Big Bang, where did energy and matter come from?" "Does the universe have a boundary, and if it does,…

Monica Adams, head librarian at Robinson Secondary in Fairfax country, Virginia, states that librarians should have the technical knowledge to support projects related to digital video editing. The process of digital video editing and the cables, storage issues and the computer system with software is described.

Some innovations in the images of cells and molecules that keep changing for new techniques and as a result of using new approaches to old methods are explored and new ways of illustrating cell and molecular structures are discussed. The three elements that play an important role in any biological image are aesthetic factors such as picture style…

A two-minute overhead demonstration using a molecular model kit is employed for illustrating the unique binding of cyclopropane. It is reported that most model kits, much like an sp (super 3) hybridized carbon atom, resist forming 60-degree bond angles.

An illustration of how excess Gibbs energies of the components in binary systems can be used to construct boiling point diagrams is given. The underlying causes of the various types of behavior of the systems in terms of intermolecular forces and the method of calculating the coexisting liquid and vapor compositions in boiling point diagrams with…

Children with learning and behavior problems often have difficulty getting through their day, to a great extent because they have difficulty organizing themselves and understanding the organization of the environment around them. Neurotypical children and adults organize themselves in many ways by using calendars, planners, lists, and so forth.…

Food preparation skills are needed to prepare low-cost, nutritious meals that meet current dietary recommendations. Research indicates that many youth and adults can read a recipe for ingredients, but they often do not know basic food preparation techniques such as how to broil, fold, dredge, baste and other cooking methods. To address the need to…

We present and discuss three examples of misapplication of the notion of conditional probability. In each example, we present the problem along with a published and/or well-known incorrect--but seemingly plausible--solution. We then give a careful treatment of the correct solution, in large part to show how careful application of basic probability…

Students analyze a photograph to solve mathematical questions related to the images captured in the photograph.

Practice posters, with pictures and captions, are useful for controlled practice of vocabulary and structures in an EFL context. The author has found many advantages of using posters with beginners in a high school setting. Student led review gets students active, increases autonomy and improves confidence. The use of small groups is effective…

Graphical User Interfaces (GUIs) are pervasive elements of most modern technical software and represent a convenient tool for student instruction. For example, GUIs are used for [chemical] process design software (e.g., CHEMCAD, PRO/II and ASPEN) typically encountered in the senior capstone course. Drag and drop aspects of GUIs are challenging for…
