| 摘要: | 近年來，行動載具與電子期刊為兩項重要的科技以支援教與學，行動載具具
備便利性、高彈性與無所不在等優點，電子期刊則是具備快速存取、易於下載等
優勢，上述優點可以吸引許多使用者藉著行動載具來閱讀電子期刊，然而，使用
者擁有不同的特質，因此必須考慮每個人的個別差異性，在眾多的個別差異性中，
認知風格為一個重要的因子，然而過去鮮少有研究探討認知風格如何影響使用者
在行動載具的環境下使用電子期刊。為此，本研究進行了兩個實證研究，實驗一
探討在行動載具的環境下，認知風格對於電子期刊之搜尋行為的影響。同樣在行
動載具的環境下，實驗二探討認知風格對於電子期刊使用者介面設計偏好的影
響。
實驗結果證實此兩個實驗之間具有「果」與「因」的關係，更精確地說，在
實驗一中使用者所展現的搜尋行為，可由實驗二使用者對於使用者介面設計之偏
好來解釋其背後的原因。例如，在實驗一中，整體型使用者出現放大縮小螢幕與
負向情緒呈現正相關的結果，而在實驗二中，整體型使用者的放大縮小螢幕與過
多的資訊呈現正相關，故可推論可能是因為頁面資訊呈現過多導致其必須不停放
大縮小螢幕，進而造成負向情緒的出現。然而針對序列型使用者而言，實驗一中
顯示負向情緒與橫向螢幕的操作呈現正相關，然而在實驗二的結果顯示其認為版
面編排並不具備一致性，也就是說，版面編排的不一致可能讓序列型使用者必須
在橫向與直向螢幕中切換，因此導致負向情緒的產生。最後，本研究也根據其因
與果的關係建立了使用者模型，此使用者模型可以幫助設計者根據每一位使用者
的特質建立適合的行動式電子期刊系統，以容納使用者的個別差異性。;In recent years, mobile devices and electronic journals have been two useful digital technologies to support student learning. The mobile devices provide many advantages, e.g., convenience, flexibility and ubiquitous information access. On the other hand, the electronic journals also provide some benefits, including the speed of access and the ability to download. Such benefits attract more users to access electronic journals with mobile devices. However, users have heterogeneous backgrounds, in terms of their knowledge, skills and needs. Thus, individual differences are essential issues. Among various individual differences, cognitive styles play an important role. However, there is a lack of studies to investigate the effects of cognitive styles on users’ reactions to the use of electronic journals via mobile devices.
To this end, the research presented in this dissertation conducted two empirical studies to examine how different cognitive style groups use electronic journals differently in the context of mobile devices. Study One investigates the search behavior of electronic journals while Study Two examines users’ perception and preferences for the interface design of the electronic journals. Results from these two studies reveal that a cause-and-consequence relationship exists between them. More specifically, the results from Study One can be considered as the consequences while those from Study Two can be regarded as the causes. In other words, how users react to the interface design of the electronic journals can be applied to explain why they demonstrate such search behavior.
For instance, the results from Study One suggest that Holists showed negative emotion when zooming in/out screens. On the other hand, the results from Study Two indicated that Holists thought that excessive functions and information were displayed by this electronic journal. It could be inferred from these results that Holists showed negative emotions with zooming in/out screens probably because too many functions and too much information were provided by this electronic journal. On the other hand, the results from Study One show that Serialists showed negative emotion when using the horizontal screen. Besides, the results from Study Two indicated that Serialists perceived that the design of interface configuration on this electronic journal is inconsistent. Due to such an inconsistent interface configuration, Serialists might frequently need to switch between the horizontal screen and vertical screen. This might be the reason why Serialists would show negative emotion when using horizontal screens. Based on the results of each study, the user models are produced. These models can be applied to develop mobile electronic journals that can accommodate users’ individual differences. |
