The use of visual metaphors has received growing attention in recent years, but their widespread use is not without certain challenges. The most common critique of visual metaphors in teaching indicates that they can be misleading as the meaning attributed by the recipient can be far apart from the intended one. This can make learning less…

In this qualitative case study, we investigated the role of an advanced math curriculum with language scaffolding on the development of geometric and visual-spatial reasoning skills in young mathematically promising English learners (MPELs). Specifically, we examined the effects of providing MPELs with challenging and supportive math curriculum to…

Aiming to enhance understanding of visual obstacles inherent in two-dimensional (2-D) sketches used in high school spatial geometry instruction, we propose a measure of visual difficulty based on two attributes of the sketches: potentially misleading geometrical information (PMI) and potentially helpful geometrical information (PHI). The…

In this paper, we consider theories about processes of visual perception and perception-based knowledge representation (VPR) in order to explain difficulties encountered in figural processing in junior high school geometry tasks. In order to analyze such difficulties, we take advantage of the following perspectives of VPR: (1) Perceptual…

These proceedings contain the papers of the 16th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2019), held during November 7-9, 2019, which has been organized by the International Association for Development of the Information Society (IADIS) and co-organised by University Degli Studi di Cagliari, Italy.…

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…

Investigates effects of a specific method of art instruction designed to increase the individual's ability to handle visual complexity and detail. Implications of findings for art education are also discussed. ( MG)

This holistic approach to speechreading instruction proposes: enhancement of the child's self-motivation, strategy-based instruction, an interactive processing approach that focuses on meaning and psycholinguistic guessing, bisensory instruction, and a hierarchical continuum beginning with easy, successful activities that gradually increase in…
