In the digital age, where media proliferation challenges traditional reading habits, this study investigated the impact of digital platforms on critical thinking (CT) and reading practices. Some conventional e-books may not sufficiently encourage reflective thinking or foster CT skills due to their linear nature and lack of engaging elements. Employing the Practical Inquiry Model (PIM) within the Community of Inquiry (CoI) framework, this study highlights the integration of multimedia elements and the use of students' selfies to boost engagement and social presence in a digital learning environment. This study introduced selfie role-playing reading, along with group discussions from various perspectives as an innovative pedagogy to enhance cognitive presence within the CoI, ultimately enhancing learners’ CT performance. Using a quasi-experimental design, 63 participants were grouped into single-perspective or multiple-perspective categories by narrative perspective exposure, and then engaged in online story discussions with worksheets. Reading performance was measured through a detailed examination of their CT patterns via behavioral sequential analysis. Results revealed that students in the multi-perspective groups demonstrated superior CT and reflective thinking levels, underscoring the potential of innovative e-book designs in enhancing CT. This study not only validates the importance of diverse narratives and role-playing in CT development, but also pioneers a method for analyzing such skills through behavioral sequence analysis. It signifies a leap in applying the PIM to multimedia e-book reading, offering insights for future educational strategies and CT assessment in the digital era.
