Describes a procedure for teaching the "generator orbital" (GO) approach of molecular orbital bonding in polyatomic molecules. Explains how the GO can be utilized with students in generating the vibrational, rotational, and translational modes of molecules in a completely pictorial manner. (ML)

Identifying the strengths of visual processing in high school mathematics is considered. The development of an instrument to assess mathematical processing is described. Then the kinds of visual imagery found in children in England and Natal are presented, along with difficulties and benefits experienced by visualizers. (MNS)

Sex differences in speed of solving mental rotation problems were replicated but college men and women were alike in frequency of use of algorithms to solve problems. The most frequent algorithm involved encoding stimuli in working memory, mental rotation of one to orientation of the other, comparison, and response. (Author/RD)

One hundred and seven 5th-8th graders were tested on spatial rotation multiple-choice items to determine age and gender differences in spatial ability. Thirty-one of them were subsequently interviewed. They were asked to explain their reasoning when solving 4 of the tested items and a problem-solving task. Features of visual and non-visual…

Multilevel visual models can make teaching and learning theories more easily understood. The idea of graphic visualizationas developed in this model utilizes three stages of abstract concept formation dealing with concrete visualization, abstract visualization, and abstract generalization, which would provide the learner with an intuitive grasp of…

This study investigates the visual information storage capacity in 5-, 8-, 11-, and 21-year olds. A partial report technique is used to assess the amount of information that children can take in and what the course of information loss was over time. (DP)

Studies support the hypothesis that images aroused by discreet verbal stimuli can be integrated into complex images with the result that: (a) storage capacity requirements are reduced, and (b) recall of one component of the image leads to effective redintegration of the rest. (JB)

Selects technical and popular writings from three scientists in each of four fields, and finds differences in the visual-verbal imagery which each field uses. (MB)

The effects of rate repetition, self-generated visualization, and supplied visuals on the memorization of concrete noun-word pairs were investigated using 27 gifted children in grades four to six. The hypothesis that self-generated imagery techniques would be superior to supplied visuals was not supported. (Author/PN)

Experiments were performed to determine the contribution of imagery and semantic factors to the hypermnesia effect (increases in retention over successive recall attempts). Results showed that hypermnesia accompanies meaningful processing regardless of whether verbal or imagery encoding is emphasized. Semantic elaboration increases reminiscence…

Compared verbal and visual encoding using the picture superiority effect. One experiment found an interaction between age and type of material. In other experiments, the picture superiority effect was found in both age groups with no interaction. Performing a semantic-orienting task had no effect on recall. (Author/RC)

Recent research on visual imagery mnemonic techniques is compared to research in the late 1800s and early 1900s. Results of recent research are discussed in terms of practical implications for education. (Author/MH)
