Students will form discussion groups (3-5 students in a group). Each group will be asked to design a mobile app for the class by using the Six Thinking Hat strategy. Each group will present the ideas for the app to the class. Each student will randomly pick a color card from a box. Depending on the color they picked, that will be the "hat" they use during the group discussion. Students will have a chance to embody the cognitive function of the hat color they picked in the process of designing the mobile app
