在網路蓬勃的資訊時代，螢幕圖像傳達帶給學習者的資訊多元且複雜，圖像可以幫助學習者在閱讀大量訊息時，快速理解其意義，因此，圖像學習是學習者喜愛的學習方式之一。在螢幕前的學習歷程中，圖像訊息提供人們共同的視覺傳達基礎。本研究針對學習者對不同圖像真實度的偏好來探究圖像資訊的視覺傳達效果，研究共分為兩個階段，第一階段探討學習者對螢幕圖像真實度之偏好情形，進行重複實驗二因子變異數分析；第二階段是以類神經網絡建立非線性預測模型，應證第一階段調查的結果。本研究的結果發現，不同真實度的螢幕圖像與偏好有極大的關條，「中真實度」圖像受到較多學習者的喜愛。

In the age of internet and information, images on screens have brought learners diverse and complex information. Images can help learner perceive meanings, and thus become important media of learning. In screens based digital learning, images information pro ides visual communication bases of human common experiences. This paper focuses on the visual realism in images information. Learners' preference are investigated. The procedures are divided into two stages. In the first stage, learners' preference for visual realism of images on screens is investigated. Investigated data are analyzed by Two-Way ANOVA (analyses of variance) with repeated measures. In the second stage, the neural network is utilized to model and predict investigated results of the first stage. Investigated results show that there are connections between visual realism of images and learners' preference.
