Evaluation of E-Textbook Quality Using the Refined Kano Model and Importance-Satisfaction Analysis
Abstract: E-books are popular in schools, many teachers have adopted e-textbooks in classrooms. However, the quality standards for e-textbooks are still incomplete. Schools and publishers demand a quality evaluation method for selecting e-textbooks or making improvements. This study aims to develop a quality evaluation scale for e-textbooks, and apply it to determine the quality attributes of e-textbooks using the refined Kano model and importance-satisfaction (I-S) matrix. Based on the e-book’s literatures and standards, an e-textbook quality scale (e-TQS) was developed, and validated by 183 elementary school teachers. The e-TQS was used to measure elementary science e-textbooks published in Taiwan through the refined Kano model and I-S matrix. Results showed that the e-TQS possesses acceptable validity and reliability. A number of quality attributes to be improved for elementary science e-textbooks were identified. Implications for e-textbooks quality evaluation are discussed.
