隨著時代的進步，科技產品日新月異，數位內容產業也跟著受影響，在加上行動載具的普及化，促使數位化教材的開發，在教材設計上的學習及應用，可以提供更多元化且更豐富的內容。但是該以何種呈現方式將數位化教材呈現在行動載具上，對於學習者的學習成效較有幫助，牽涉到有多少個資訊量呈現在同一個畫面上，過多的資訊量呈現在同一畫面上，容易造成學習上的認知負荷。因此，本研究試圖找出最適合在七吋平板電腦上的資訊量呈現數量，何者對於學習成效最有幫助。但是，如果教材內容過於簡單，資訊量的多寡與學習者的記憶效果較無明顯的差異，所以本研究採用網站經驗設計與使用者研究優使性2.0書籍中「介面設計原則」、「常見的設計問題」，作為製作電子書數位化教材之實驗科目書籍。
本研究依據動機與目的，並藉由文獻的整理與探討之後，發展出研究的架構，其中的實驗分為兩個部份，實驗（一）測驗不同資訊量，找出在單頁頁面呈現時最佳的資訊量為何，實驗（二）測驗不同呈現方式，再依據實驗（一）不同資訊量所找出的最佳單頁頁面呈現資訊量，製作電子書數位化教材，比較使用重點提示呈現方式進行學習，對於學習成效是否有明顯差異。
Digital content industry followed the rapid growth and the popularization of mobile devices. With the progress of technology products The trend prompts the development of digital textbooks, learning materials and its application. It is important to investigate how the digitalized materials presented and how many pieces of information presented on mobile devices that help learning effects. Excessive amount of information presented on the screen will increase learning cognitive load and negatively impact learning outcome. This study attempts to identify the most suitable amount of information on the seven-inch tablets that leads to effective learning. When the content is too simple, there will be no significant differences among different amount of information, the research used the website programming textbooks, focusing on teaching the principle about website on the 7-inch tablet and tried to find out the most suitable amount of information presented on the screen.
There are two experiments in this research, one is to find out the most suitable amount of chunks to learn on 7-inch tablets, the other is to investigate the most effective presentation style on 7-inch tablets.
