Abstract

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.

디지털교과서는 기존의 종이 기반 교과서에 멀티미디어 콘텐츠나 대화식 시뮬레이션, 대화형 퀴즈 및 콘텐츠 공유와 같은 다양한 기능이 추가된 교과서다. 디지털교과서는 머지않은 장래에 전통적인 종이 기반 교과서를 점차적으로 대체 할 것이라 예상된다. 디지털교과서 개발 시 모바일에서 접속을 고려하여, 모바일 애플리케이션을 개발할 경우 어떤 개발 방식을 선택할 것인가 하는 것은, 정보공유, 플랫폼 독립성, 성능 등을 종합적으로 고려해 정해져야 한다. 네이티브, 웹, 하이브리드로 대표되는 모바일 애플리케이션 개발 방식 중 본 논문에서는 디지털교과서 개발에 고려해야할 개발 가이드라인을 제시하였다. HTML5는 웹 응용 프로그램에 비디오 클립, 플래시 무비 및 시뮬레이션 기반의 데모와 같은 풍부한 멀티미디어를 통합할 수 있게 해주는 새로운 웹표준이며, 여러 플랫폼에서 실행할 수 있는 플랫폼 독립적인 기능을 제공한다. 디지털교과서에 사용될 응용프로그램 개발을 위한 3가지 개발법의 적합성을 조사하기 위해 본 논문에서는 또한, HTML5 및 JavaScript를 이용하여 프로토타입을 제작하고, 이러한 장점을 지닌 HTML5가 디지털교과서개발에 사용될 경우 예상되는 문제점(예: 웹 브라우저와의 호환성)을 분석하였다.
