5. Conclusions
Delicate illustrations, vivid narrations and animations in e-books contributed to higher levels of motivation and engagement in readers (Ciampa, 2012a; Grant, 2004; Lewin, 2000). However, the interactive features that were not congruent with the storyline may cause extraneous burden that distracted learners from the text, thereby impeding reading comprehension (de Jong & Bus, 2002, 2003; Korat, 2010; Labbo & Kuhn, 2000; Mayer & Moreno, 2003; Rolandelli, 1989; Schugar et al., 2013; Takacs et al., 2015; Underwood & Underwood, 1998). This study designed a high interactive e-book by incorporating three features (guidance, prompt, and feedback) that were closely connected to the storyline to facilitate the learning effects in terms of reading motivation, story comprehension and chromatics concepts (Fig. 7). Through “guidance,” the e-book triggered students’ curiosity and encouraged them to carefully observe details with different cue information. Through a “prompt,” students were requested to think of questions to fully comprehend the reading content. Through “feedback,” students could receive instant information and explanations to better comprehend the reading material or correct their misunderstanding. These three interactive functions kept setting new learning goals for students so that their curiosity was aroused and their motivation was maintained.
