Digital learning increasingly makes use of realistic visualizations, although realism can be demanding for learners. Color coding is a popular way of helping learners understand visualizations and has been found to aid in learning with detailed visualizations. However, previous research has shown that color coding must not always be an effective…

The current pandemic has highlighted the importance of hand hygiene as a preventive measure to avoid the transmission of diseases. It is a habit that should be reinforced during childhood, so that it lasts into adulthood. The main objective was to analyse and describe, through drawing, the mental schemas that 6-12 year-old pupils have about clean…

The relation between mental imagery and visual perception is a long debated topic in experimental psychology. In a recent study, Wantz, Borst, Mast, and Lobmaier (2015) demonstrated that color imagery could benefit color perception in a task that involved generating imagery in response to a cue prior to a forced-choice color discrimination task.…

Results from a number of studies indicate that the use of drafting models can positively influence the spatial visualization ability for engineering technology students. However, additional variables such as light, temperature, motion and color can play an important role but research provides inconsistent results. Considering this, a set of 5…

Several theorists believe that different types of visual cues influence cognition and behavior through learned associations; however, research provides inconsistent results. Considering this, a quasi-experimental study was done to determine if there are significant positive effects of visual cues (color blue) and to identify if a positive increase…

In argument diagrams, perceptual cues are important to aid understanding. However, we do not know what perceptual cues are used and produced to aid understanding. We present two studies in which we investigate (1) which spatial, graphical and textual elements people spontaneously use in creating for-against argument diagrams, and (2) how people…

Purpose: The purpose of this paper is to propose an effective educational system to help students assess Web site risk by providing an environment in which students can better understand a Web site's features and determine the risks of accessing the Web site for themselves. Design/methodology/approach: The authors have enhanced a prototype…

This study aims to investigate the acceptance of ICT teachers pertaining to the use of Scratch as an Algorithm Visualization (AV) software in terms of perceived ease of use and perceived usefulness. An embedded mixed method research design was used in the study, in which qualitative data were embedded in quantitative ones and used to explain the…

Visualizing molecular properties is often crucial for constructing conceptual understanding in chemistry. However, research has revealed numerous challenges surrounding students' meaningful interpretation of the relationship between the geometry and electrostatic properties of molecules. This study explored students' (n = 18) use of three visual…

Recent neuroimaging research suggests that early visual processing circuits are activated similarly during visualization and perception but have not demonstrated that the cortical activity is similar in character. We found functional equivalency in cortical activity by recording evoked potentials while color and luminance patterns were viewed and…

Under the umbrella of ubiquitous technologies, many computational artifacts have been designed to enhance the learning experience in physical settings such as classrooms or playgrounds, but few of them focus on aiding orchestration. This paper presents a systematic evaluation of the signal orchestration system (SOS) used by students for a jigsaw…

This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to…

Focuses on difficulties students have in reading images and understanding a particular domain; e.g., optics and color. Concentrates on the extent to which teachers were conscious of such difficulties and what they suggested doing to avoid possible pitfalls. (Author/MM)

Compares the results of four studies made under the auspices of the Science Teacher Training in an Information Society (STTIS) project researching the difficulties students have in reading images. The studies are compared under such categories as pre-eminence of narrative readings, real-world versus symbolic elements, verbal elements, and…

Undergraduates of different levels of ability (IQ) profited differentially from color cueing of instructional materials pertaining to the human heart. Visualization was not equally effective in achievement of different educational objectives (drawing, identification, terminology, and comprehension tests). Delayed retention of material was not…
