This paper analyzes user preferences on the basic structure of digital textbook contents based on the PDF and HTML formats. This was conducted by analysing the data from an online survey on user preferences for the representative structures of the PDF- and HTML-based digital textbook contents that are currently used on the Web. Results show that in the PDF format, the structure with TOC(Table Of Contents) links on the left screen and the main content on the right was most preferred by 82% of the respondents. In terms of the viewing method, the one that presents one page of the textbook fitted to the width of the computer screen in a single-page view was regarded as the best. Similarly, in the HTML format, the structure with TOC links on the left frame and the main content on the right using 2-frames was revealed as the most preferred by 84% of the respondents. However, the structures of the PDF- and HTML-based digital textbook contents employed by most existing Web sites go against the users' preferences. Accordingly, for digital textbook development in the future, user preferences must be considered to allow students to read the contents more easily and conveniently.

In electronic textbooks (or e-Textbooks) the traditional paper-based textbooks are enriched with multimedia contents and new features such as interactive multimedia-based simulation, interactive quizzes, and content sharing. It has been envisioned that e-Textbooks will gradually replace the traditional paper-based textbooks in classrooms in the near future. HTML5 is an emerging and promising standard that enables web applications (or apps) to incorporate rich multimedia contents such as video clips, flash movies and simulation-based demonstration, as well as to provide cross-platform functionality which allows the apps to run on a diverse range of platforms. To support rich multimedia contents and cross-platform functionality, with respect to HTML5, this paper presents the new features, compares the current trend of mobile apps (e.g., native, web-based and hybrid apps) for e-Textbook development. In order to investigate the suitability of these three development approaches for e-Textbooks, we present a case study on our recent work in developing e-Textbooks using HTML5 and JavaScript, as well as analyses the challenges associated with HTML5 features (e.g, compatibility with web browsers) for developing e-Textbooks.

전자책이란 저작물의 내용을 디지털 데이터로 CD-ROM, DVD 등 기록매체 또는 저장장치에 수록, 유·무선 통신망을 통해 전용 단말기나 컴퓨터로 이용할 수 있는 출판물을 의미한다. 전자책은 다양한 형태로(HTML, PDF, XML) 제작돼 표준이 없어 별도의 단말기를 개발 보급해야하는 문제와 함께 전자책 산업의 중복투자를 발생시켜 활성화에 어려움을 겪어왔다. 2002년 산업자원부 기술표준원은 이러한 문제를 해결하기 위해 상호운용성 등이 뛰어난 XML에 기반한 전자책 문서 표준(EBKS 1.0)안을 국가표준으로 제정하였다. 교육인적자원부에서도 2002년 '교과용 도서에 관한 규정' 을 개정, 주교재와 보완교재의 구분을 폐지해 음반이나 영상, 전자저작물 등을 활용한 전자교과서 및 지도서를 제작할 수 있도록 했다. 이러한 시대흐름에 발맞추어 본 연구에서는 XML Schema를 활용한 중학교 컴퓨터 과목의 전자교과서 문서 표준을 개발해 보고자 한다. EBKS를 비롯한 기존 연구의 대부분은 XML DTD를 이용한 표준 개발이 중심이었으나 DTD가 가진 제한점들로 인해 이미 XML Schema의 사용이 권고되고 있다.
