This course is the starting point for students pursuing or seriously considering the middle school or secondary STEM undergraduate and graduate certification pathways. This one-semester course will substitute for both TLPL101 and TLPL102, thereby accelerating the undergraduate pathway. Students will make four visits to a local middle school classroom to observe, facilitate discussions, and lead STEM lessons. Students can expect a highly collaborative, discussion-based exploration of STEM teaching and learning, classroom complexity, and social justice.
