Presents a method for graphically illustrating Le Chatelier's principle, suitable for the general chemistry undergraduate. (CS)

Describes materials designed to teach the basic skills of English as a second language to infants and nursery school children. The materials consist of a bag of soft toys which is used in play situations to teach simple language forms by drill and substitution. The learning is later reinforced by visual aids. (Author/PJM)

The article describes two groups of visual materials developed for multiply handicapped deaf teenagers. The daily living skills project includes vocabulary lists, visuals, games and a model related to household cleaning, personal grooming, or consumer skills. The occupational information project includes visuals of tools, materials, and clothing…

Presents a variety of songs in which songs and slides can be used in a multinational classroom, providing pronunciation practice and a basis for free conversation and discourse, thus improving fluency. Visual and audio cues are presented simultaneously and in sequence, thus varying the presentation. Technical aspects are also discussed. (PJM)

Summarized in chart form are data regarding published geologic maps for the 50 states and Puerto Rico. Information provided by state geologists includes scale, availability, and ordering instructions for both bedrock and surficial maps. (CS)

Organized by topic is a reading list for A- and S-level biology. Described are experiments for measuring rate of water uptake in a shoot; questions to aid students in designing experiments; rise of overhead projection to demonstrate osmosis and blood cell counting; and microbial manufacture of vinegar. (CS)

Five ideas to aid in teaching health are offered including the use of discarded household items as visual aids in health and safety; media use in health education; relating GPA to teaching competence; the use of feature films to promote health concepts and examine health problems; and identification of environmental health issues. (JMF)

The first experiment determined that verbal interference (shadowing) was detrimental to the subjects' memory of words and high similarity pictures; the second, designed to minimize the possibility that students would sort through the pictures, indicated that verbal interference did not decrease memory of high similarity pictures. (Author/JEG)

Examines various approaches to the teaching of word meanings in the second language classroom, including the use of translation, visual aids, and direct methods. (AM)

Describes the use of images on an overhead projector to explain concepts like centrifugal force and Cariolis force in such a way that students can realize that they are pseudo-forces, i.e., observations arising only from referring phenomena to an accelerating reference system. (MLH)

Describes how to construct a device that will show interference fringes formed by multiple reflections in an air gap between two partially silvered glass surfaces. (MLH)

Describes a new technique for presenting shadow plays with a projector and silhouette figures, manipulated individually. The procedure was developed at the Research and Development Center for Objective Teaching and Learning Procedures at Paderborn. (IFS/WGA)

Effective use of visual illustration entails consideration of specific instructional purposes, method of presentation, student characteristics, type of objectives, and cuing techniques. (LS)

Describes a study in which engineering students who were shown accompanying slides during lecture scored significantly higher on a subsequent quiz than a control section. (MLH)

The report reviews the origins, development, and current state of the major marking and visual-display surfaces; considers the optimum installation and use of these devices; contains a bibliography, a decision- making checklist, and list of suppliers of the different types of materials. (MLF)
