When students care, they work harder having a sense of ownership. Using students' own judgment takes away the idea of just doing an exercise or following a set of directions. Students can have input and control (to a certain extent) over many aspects of a project. Students can even write their own driving questions and decide how they want to investigate it, demonstrate what they have learned, and make their work public.
Promote creativity and innovation. Encourage students to think critically and outside the box to develop innovative solutions.
Provide support and guidance for complex tasks. Include resources to create the project ( workshops, mentorship). Guide students with different resources such as books, websites, etc.
Students begin to research and explore the possible solutions for the driving question given.
Promote student's voice and choice. Let students decide the product, the process, determine what they know, identify what they need to know, investigate and evaluate their findings.
