Laurie believes that comfort and confidence in these areas is critical to students’ ability to thrive in school and in their careers, but also to ensure a healthy and productive democratic society. She leads TERC as its research scientists engage in research and development efforts aimed at enhancing STEM education practices, experiences, assessments, materials, and tools in formal and informal learning settings.
