As technology advances, the realization of seamless learning has linked in-class and out-of-class learning activities, between which the boundary is blurring. On the other hand, reading is not only the foundation of lifelong learning, but also the fundamental of learning. Therefore, how to motivate students to develop interest and habit of reading is vital for the success of learning. Prior to this project, we have promoted a reading activity, called Modeled Sustained Silent Reading (MSSR) in the classrooms of elementary schools. Preliminary studies show some positive effects on students’ reading. However, reading should not be limited by time and space. In other words, reading should not only happen in classroom, but also take place outside classrooms, especially at home. To this end, this project continues our previous studies and incorporates seamless learning with the support of digital technology to carry out MSSR for students at home, where parents play the role model for their children, guide children how to read, and support children’s participation of MSSR. By doing so, both MSSR activities in class and at home will be linked together. To achieve this goal of seamless learning for MSSR, this project will establish an online learning community platform, named Parent-Teacher-Ark, which can build up a common reading space of interactions among teachers, parents, and students. This Parent-Teacher-Ark consists of features (i) online courses: it facilitates parents to learn about the concepts of MSSR and procedures how to carry out at home as well as how to enhance parent-child relationship through the process; (ii) reading portfolio: adopted as a linkage between students’ reading records and writing related to the reading (such as recommendations of books to classmates), the portfolio extends student reading at classroom to reading at home; (iii) parent-teacher communication: it helps the communication between parents and teachers so that they can support better their children’s reading. Through the establishment and deployment of this platform, children, parents, and teachers can discuss and share their reading experience and support each other, gradually developing a reading community. By linking reading from classroom to home and from home to classroom, family reading habit may ultimately be taken on by every family, and every child may become a lifelong reader in Taiwan.
