Loyola University Chicago’s Teaching, Learning and Leading with Schools and Communities (TLLSC) program is an ambitious break from traditional, university-based teacher preparation models. This clinically-based initial teacher preparation program, fully embedded in local schools and community organizations, takes an ecological perspective on the development of sophisticated, reflective, and resilient elementary science educators who are able to prepare and inspire students and act as agents of change in their schools. This paper describes how TLLSC leverages time for science across elementary teacher candidates’ entire program through an emphasis on practitioner inquiry and integrated (inter- and trans-disciplinary) teaching and learning. TLLSC’s innovative approach is designed to foster STEM habits of mind, integrate scientific practices, and support candidates’ ongoing self-examination of personal and social applications of science for themselves and their future students.
