This project team will develop and test a prototype of Emotion Explorer, a web-based program intended for kindergarten to Grade 2 students to create interactive storybooks to strengthen emotional literacy. Using the prototype, students will read and listen to storybooks focused on emotional literacy topics (i.e., emotion recognition, labeling, understanding, expression, regulation), after which they will design and publish their own storybook. In the pilot study with 4 Grade 1 classes, the researchers will examine whether the prototype functions as planned, if teachers are able to implement the intervention, and whether students are engaged and can create storybooks.
