使用性

網路資訊時代，大量的資訊與資源皆透過網路傳播與擷取，影響範圍無遠弗屆。透過網路傳遞科學知識與資訊，逐漸成為一種新的推廣科學普及與科學教育的方式。國立臺灣師範大學圖書館規劃建置一個科普閱讀網站介紹推廣科普好書、促進科學知識與新知的傳播，以形塑科普閱讀風氣；另一方面，亦希冀可藉此提供科學閱讀方法與教學資源，協助各級學校教師推動科學普及與科普閱讀，以提升學生整體科學素養，將科普閱讀習慣深植。本研究主要以科普閱讀網使用者為中心，分五個階段進行研究：第一階段是透過網站內容分析法收集17 個華文科普相關網站，進行網站架構及標籤項目的分析整理；第二階段進行使用者需求訪談；第三階段實施卡片分類法實驗以瞭解使用者對科普閱讀網站組織架構內容及標籤認知與命名方式；第四階段進行使用者經驗訪談；第五階段進行使用性測試，以了解科普閱讀網的使用者經驗，發掘其使用目標、動機、偏好與特性等，瞭解在實際使用科普閱讀網的使用者行為及面臨使用性之問題。透過本研究獲致以下結論：（一）透過卡片分類法與群集分析方式整理歸納使用者對網站內容組織分類與標籤命名意見，發展一廣度9 類、深度2 層的科普閱讀網站架構；（二）瞭解使用者利用科普閱讀網站之使用目標、動機及其使用偏好；（三）瞭解科普閱讀網站之使用性問題，包括組織分類、標籤命名、搜尋系統、以及介面或操作設計等問題，最後提出相應解決的兩項建議，以作為科普閱讀網後續經營維護之參考。

Nowadays, a lot of information and resources are spread and retrieved through the Internet. The impact of internet is wide. It gradually becomes a new way to promote the popularization of science and science education through the internet. National Taiwan Normal University Library has built a popular science reading website to introduce popular scientific books and promote the dissemination of scientific knowledge and new knowledge. In addition, this website also intends to provide scientific reading methods for science teachers at all levels to enhance students' scientific literacy and cultivate the science reading habits in daily life. Divided into five stages, this study focuses on the users of popular science reading website. In the first stage, we collected seventeen Chinese popular science reading websites to analyze the architectures and the labels of the websites. In the second stage, we interviewed the users to understand their demands. In the third stage, we used the card sorting method to understand whether the users were aware of the architecture of the websites and the significance of the naming of the labels. We interviewed the users regarding the users’ experiences in the fourth stage. In the fifth stage,we conducted the Usability Test to understand users’ experiences, purposes, motivations, preferences, and characteristics in order to know users’ behaviors and the problems they encounter. This study has several conclusions. First, we concluded users’ opinions towards the architecture and labels of the website through card sorting method and cluster analysis. Then we developed a website of nine-category and 2-level architecture. Second, we got to know users’ purposes, motivations, and preferences in using the popular science website. Third, we understood the usability problems regarding organizations, label-naming, search functions, and the interface of operative designs. Finally, this study proposes two suggestions to solve the problems to maintain the popular science reading website in the future.

本研究試圖建立一個美食部落格介面的使用性評估模型，做為使用性評估的指引。首先收集部落格介面設計準則與使用性評估的相關研究，並從中彙整出內容易用性、介面互動性、版型設計等3 個構面，合計含有21 個項目的部落格介面評估模型。本研究的樣本是從個人美食部落格、公司美食部落格及Alexa 排名美食部落格等3 類中選取15 個樣本。評估結果顯示，首先，3 個類群的代表性樣本均比同類型一般隨機樣本的表現優良；其次，整體來說，Alexa 排名美食部落格表現較其他2 類為優，個人美食部落格和公司美食部落格則相差不多。以個別評估項目來看，3 個類群在適當使用圖像和網站區塊二個項目上均有嚴重的使用性問題。個人美食部落格另外在一致性、易於瀏覽的頁面長度、連接的穩定性、主題一致性、個別文章點擊之人氣數量等5 個項目上有嚴重的使用性問題；公司美食部落格則是在一致性和部落客自身意見等2 個項目上有嚴重的使用性問題；Alexa排名美食部落格則只有在文章分類1 個項目上有嚴重的使用性問題。

In this work, based on related researches of user interface design and usability evaluation in food blogs, we first develop a usability evaluation model, incorporating three perspectives: content usability, interactive interface, and layout design, with 21 evaluation items in total. The 15 evaluation samples are chosen from three types of food blogs: personal food blogs, company food blogs, and Alexa food blogs. This investigation proposes several important findings. Firstly, in each of these three types of food blogs, the most famous blog is better designed than those randomly selected blogs. Secondly, Alexa food blogs are overall performed better than the other two types of food blogs. In addition, personal food blogs are scored more or less equal to company food blogs. From the perspective of each individual evaluated item, all three types of blogs have severe usability problems in two items: improper use images and website blocks. In addition, personal food blogs have severe usability problems in five other items: consistency, navigable age length, stable connection, consistent theme, and individual article cumulative popularity. Company food blogs have severe usability problems in two other items: consistency and opinionated blogger articles. Alexa food blogs have severe usability problem in only one more item: article classification.
