보편적 학습설계(UDL) 원리에 따른 전자책 개발을 위한 사용성 평가 연구

초록

This study aims to design and develop e-books which can supplement learning at a school context in a more effective and user-friendly way. To achieve this purpose, a traditional paper-book dealing with multicultural education published by UNESCO was selected to design and develop a model e-book. It was chosen because multicultural education is one of the hot fields at Korean school contexts in recent days. The e-book was mainly designed based on UDL principles to assist students who have difficulties with recognition, strategic, and affective aspects according to brain research and design principles from the book-builder CAST is providing as an authoring tool for e-books. Then, the first low-fidelity prototype was implemented with Microsoft Power-point to find empirical user requirements and the design strategies from a user-friendly perspective by conducting a usability evaluation at an early development stage. In an usability evaluation, heuristics evaluation method which is suggested as an easy and quick usability testing technique by Nielsen at an early stage was adopted. For this, heuristics were developed with consideration of students with special needs and educational aspects as well as interaction and user interface. The findings help to improve the e-book design. This study has implications to provide a model e-book which can be utilized in a school context as supplementary learning resources and to promote reading for students who has recognition, strategic, and affective problems.
