Four experiments demonstrated that mental images are functionally equivalent to physical errors of movement in producing changes in visual-motor coordination, at both central and peripheral levels of the visual-motor system. Subjects observed or imagined pointing errors after pointing movements were completed. Imagery vividness ratings were also…

This second article in a series on children's artistic learning reviews the developmental process of symbolization and symbol representation by young children and analyzes the symbolism in works by three boys. Practical teaching considerations are discussed. For part one of this series, see the September, 1980 issue of this journal. (SJL)

Explains that a Middle School Literacy Teacher Expert supports and guides teachers with innovative strategies to help students master basic literacy skills to become lifelong learners. Explains the A.C.T.I.V.E. strategy to encourage students to ask, comment, track down, infer, visualize, and Eureka! (synthesize). (PM)

Describes a novel modeling and simulation package and assesses its impact on students' understanding of chemistry. Connected Chemistry was implemented inside the NetLogo modeling environment. Using Connected Chemistry, students employed problem -solving techniques characterized by stronger attempts at conceptual understanding and logical…

Describes the design and implementation of a prototype visualization system, AuthorLink, to enhance author searching. AuthorLink is based on author co-citation analysis and visualization mapping algorithms. AuthorLink produces interactive author maps in real time from a database of 1.26 million records supplied by the Institute for Scientific…

This article discusses the acquisition of self-control using relaxation and guided imagery. These methods can be used in conjunction with other effective teaching tools to enable people who are deaf-blind to lead self-determined lives. An audiotape guided imagery script and a guided imagery script on index cards are described. (Contains…

Examines the impact of computer animations that illustrate chemical reactions occurring inside a battery on students enrolled in a college introductory chemistry course. Implies that instructor-guided animations may help students acquire a better understanding of targeted chemistry concepts, and that the relationship between narration, spatial…

Presents interactive parabolas created from straight segments using a dynamic geometry software and its web component. (Author/KHR)

Describes the visualization of a navigation classification scheme in an information retrieval (IR) system. Highlights include Charles Cutter's rules for creating a dictionary catalog; user needs; an example of undergraduate research using this scheme; and user interaction with the IR system. (Contains 64 references.) (Author/LRW)

Discusses concept of time in therapy, presenting theoretical and clinical foundations to illustrate the validity of guiding patients into past lives and future lifetimes through hypnosis to resolve self-defeating sequences. (Author/TE)

Provided are activities for creating tangrams. Illustrates how to make tangrams and use them. (YP)

Describes environments for concretely enacting multiplication and division. Discusses difficulties occurring when students use one of the concrete environments to model situations involving modified environments. (YP)

Discusses a technique for graphically composing functions. Describes three-step composition procedures in two- and three-dimensional rectangular coordinate systems. Provides three examples. (YP)

Describes learning difficulties students may have with the basic notions of linear algebra and three phases of abstraction. Discusses results of a program based on the abstraction process. (YP)

Presents a historical overview of visualization as a cognitive strategy in human creativity, discovery, and problem-solving.
