The purpose of this article is to investigate the effect of visual working memory, the types and contents of graphic annotations on English learning. The participants of the experiments were 5th and 6th graders. The result showed that animation was effective only in the word test for children with large visual working memory, whereas text-only-annotation yielded better performance in the comprehension test in Experiment 1. The effect of relevance of animations was tested in Experiment 2. Context-relevant-animations yielded better comprehension than the animations denoting the typical meaning, whereas the opposite pattern was reported in the word test. The result of the two experiments was interpreted in terms of cognitive load theory and the generative theory of multimedia learning.

In this study, we examined the effects of background and underline on the readability of displayed text. The background was placed on every other line and the underline was done with every line of the text. The effect of adding color to the background and underline was also of primary concern. Twenty subjects were tested on their reading efficiency (i.e. time-to-read and comprehension) and subjective preference of different text format presented on a LCD. Result showed that for the background condition, the background with green format significantly decreased the time-to-read as compared to the format without any background. The results of ANOVA on comprehension and subjective preference were also consistent with this finding. For the underline condition, otherwise, the underline with yellow format yielded higher speed and better comprehension. The results imply that adding background or underlines with appropriate colors can be an additional and useful way of improving text readability.

If we are to analyze certain chromatic phenomena, we must first know what “color” is； we must identify its essential characteristics in an effort to achieve a more rational comprehension of visual phenomena in general. What is difficult for most observers to grasp is that seeing colors is no different than seeing shapes. Indeed, all aspects of the objects in the world surrounding us-shape, size, distance, movement, as well as color--are seen via our perceptual system. (omitted)

Icon is a small graphic which represents a particular function in computer interface. Comprehension and learning of icons are needed for using them because they represent some meanings. This study was conducted to examine which were more important factors in using icons. First, representational characteristics of icons were examined. Second, using a eyetracker, the way of coding of redundant display was examined which removed obscurity of display and gave more meaning to a user. Icons using attribute of object and direct discription of action were more efficient than icons of other representational form in comprehension. Redundant display was proved to have some advantages, especially when the icons had low familarity. Visual information processing of icons were discussed according to familarity and learning.

Due to the rapid proliferation of the web in recent years, many educators seek to improve the effectiveness of their instruction by providing innovative web-based course material to their students. Lots of web-based education contents are developed especially. They help to teach and train students. They expand widely due to repetition learning any time, any where. In this paper we implemented usage of C functions, quizes for checking comprehension of statements in C programming lecture and developed scenario helping concepts, algorithm comprehension. We made them web-based visual representation. They were implemented as FLASH animations or Java applets. They were well received by students.

The purpose of this study is to investigate the research trends and the present conditions of real digital texts on "Visual Transformation." For the purpose of this study adopted two different methods: meta analysis and case study. The research trends on visual transformation of digital text were investigated through analyzing the total of 167 literature by means of synthetic meta analysis. Relevant literature was categorized into three types of research: functional, dynamic, and interactional transformation. The type of literature and research methods in each literature were analyzed. The present conditions of real digital texts on visual transformation were investigated by means of case study. The well designed 12 e-learning contents selected and analyzed in terms of the analysis framework which was drawn by the research trends. The results suggested problems as follows in designing e-learning contents. Firstly, there were some cases that did not follow the basic design principles related to typography. Secondly, the content was just provided in each learning steps without consideration of design to enhance text comprehension in many cases. Thirdly, web technology adequately was not applied to design e-learning contents.

With the advent of smart media, short and fast-paced video content appeared, and conditions for viewing changed to viewing in environments where the perception is dispersed due to distracting and complicated external situations in a short period of time. Accordingly, smart media videos are quickly delivering meaning while keeping the eyes of viewers who lack patience. Our eyes and brain have a hard time accepting image information that flows through the constraints of a small screen. Our visual perception is limited in terms of acceptable visual information and, in particular, less cognition in moving images, so the production of smart media images should be directed in a way that enhances perceptual understanding. To be able to effectively communicate what you want to talk about while reducing the visual burden, intuitive image comprehension is needed by applying intuitiveness and behavioral induction to the moving images. Close-up shot, stable structure such as frontality and three-division structure, and color have such 'visual affordance' Therefore we need to use that device appropriately.

For the instruction of units dealing with the conic section, the most important factor that we need to consider is the connections. In other words, the algebraic approach and the geometric approach should be instructed in parallel at the same time. In particular, for the students of low proficiency who are not good at algebraic operation, the geometric approach that employs visual representation, expressing the conic section's characteristic in a dynamic manner, is an important and effective method. For this, during this research, to suggest the importance of dynamic visual representation based on GeoGebra in teaching Quadratic Curve, we taught an experimental class that suggests the instruction method which maximizes the visual representation and analyzed changes in the representation of students by analyzing the part related to the unit of a parabola from units dealing with a conic section in the "Geometry and Vector" textbook and activity book.

Recently, with an emphasis on software proficiency, universities are providing software education to all students regardless of their majors. However, non-majors often lack motivation for software education and perceive the unfamiliar learning content as more challenging. To address this issue, tailored software education according to the learners' characteristics is essential. Art students, for instance, with their strong visual comprehension and expressive abilities, can benefit from utilizing visual literacy to enhance the effectiveness of programming education. In this study, we propose decomposing everyday problems into flowcharts and pseudocode to construct procedural and visual images. Using the educational programming language PlayBot, we aim to analyze the effectiveness of teaching by coding to solve problems. Through this approach, students are expected to grasp programming concepts, understand problem-solving processes through computational thinking, and acquire skills to apply programming in their respective fields.
