The TeachEngineering digital library is a collection of searchable, standards-based, classroom-tested P-12 engineering curricula for use in science and math classrooms (Sullivan et al., 2005). Its inquiry-based lessons and hands-on activities use real-life engineering as a vehicle for the integration of science and math in P-12 classrooms. Mapped to educational content standards, the activities are age-appropriate, inexpensive to conduct, and relevant to students’ daily lives, helping science and math come alive. The collection is a powerful resource for those in P-12 or higher education, industry and professional communities wanting to improve STEM literacy, to engage young students in the joys and creativity of engineering and the design process, and to increase the number of students pursuing STEM careers.This paper investigates TeachEngineering usage trends and curricular submission statistics. Specifically, we analyze the submission process for curriculum contributed from external authors, suggest practices for submitting new curriculum, and discuss possible support avenues for future submissions.
