The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

THE SYMPTOMATOLOGY AND TREATMENT OF DYSLEXIA ARE DISCUSSED. A DESCRIPTION OF THE DYNAMIC NATURE OF DYSLEXIA, INCLUDING VISUAL PERCEPTION, AUDITORY PERCEPTION AND SPEECH, NEUROLOGICAL ABNORMALITIES, AND AUDITORY-VISUAL RELATIONSHIPS, IS PRESENTED. TREATMENT FOR DYSLEXIC CHILDREN IS DEPENDENT ON DIAGNOSIS AND CONSTANT EVALUATION. SOME METHODS OF…

Talks presented by Doris Johnson and Regina Cicci at an institute for teachers of the educationally handicapped are summarized and include identification and remediation of auditory receptive language disorders, disorders of spelling and written language, an analysis of reading methods, an analysis check list, disorders of quantitative thinking,…

Project SEE was designed as a structured kindergarten and first grade program for the development of visual perception. Short daily lessons were given to an entire kindergarten class simultaneously and were centered around a set of 40 cards containing various lines and shapes. Children were asked to analyze and describe these elements on the…

Most schools teach the triadic color system, utilizing red, blue, and yellow as primary colors. Other systems, such as additive and subtractive color systems, Munsell's Color Notation System, and the Hering Opponent Color Theory, can broaden children's concepts and free them to better choose color in their own work.

Designed to determine the effects of multiple and linear imagery on performance of a visual location task, this study also considered whether scores on such a task were affected by the interaction of presentation mode (multiple and linear imagery) and perceptual type (haptic and visual). (Author/JEG)

The study with 34 gifted fifth-grade students found that a concrete sequential approach to developing visual literacy was more effective than an abstract visualization approach. Subjects either received guided visualization or direct instruction on such art concepts as shape, form, line, color, perspective, variety, and unity. (DB)

In tennis as well as in other racket/paddle sports, simply watching the ball does not guarantee success in hitting the ball to the desired location. Teachers and coaches should teach players to integrate available visual, spatial, and kinesthetic information. Several drills for good ball contact are outlined. (IAH)

Talkers vary widely in the ease or difficulty with which they can be speechread. Examined are variables contributing to visual intelligibility, comparisons with auditory intelligibility, the range of talker differences, characteristics accounting for these differences (facial cues, extrafacial gestures, rate, and rhythm), and implications for…

Results of 6 experiments involving 200 Australian elementary and secondary school students support the hypothesis that negative consequences of the split attention effect in geometry may be ameliorated by presenting geometry statements in auditory rather than visual form. (SLD)

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

In this article, we detail how to produce two inexpensive micromanipulators that offer high precision (approximately 25 micrometers) along a single axis of movement. The more expensive of the designs provides improved versatility along multiple axes. Both manipulators offer substantial savings over commercially available micromanipulators with…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…
