Development of nudge system: To nudge other students through their tablet

We develop a system that students can use to nudge other students thought their tablet, thus developing self-regulation learning skills during class. This paper presents the nudge system functions and interface design. A key feature of the nudge system is its division into four components: note taking, learning log collection, visualization of learning, and learning log confirmation. The note-taking function enable learners to write, delete, and underline notes directly on distributed materials. The visualization function of learning from distributed materials is related to the lesson (.pdf) that has been sent to the tablet device; when multiple learners take notes or underlines the same materials, the approximate section of the materials on other learners’ tablet devices can be highlighted in color. As more learners take notes in the same section, the section color becomes darker. We think that this function will enable learners to use reflection, forethought, and performance assessment to evaluate their own learning strategies during class. The learning log collection function collects contents written on the class materials by hand. Additionally, the learning log collection function records to the note completion of the learners. The learning log confirmation function enables the teacher to see the note-taking process of all of the learners after class.
