The employment demands in STEM fields grew twice as fast as employment in non-STEM fields in the last decade, making it a matter of national importance to educate the next generation about science, engineering and the scientific process. The need to educate students about STEM is particularly pronounced in low-income, rural communities where: i) students may perceive that STEM learning has little relevance to their lives; ii) there are little, if any, STEM-related resources and infrastructure available at their schools or in their immediate areas; and iii) STEM teachers, usually one per school, often teach out of their area expertise, and lack a network from which they can learn and with which they can share experiences. Through the proposed project, middle school teachers in low-income, rural communities will partner with Dartmouth faculty and graduate students and professional science educators at the Montshire Museum of Science to develop sustainable STEM curricular units for their schools. These crosscutting units will include a series of hands-on, investigative, active learning, and standards-aligned lessons based in part on engineering design principles that may be used annually for the betterment of student learning. Once developed and tested in a classroom setting in our four pilot schools, the units will be made available to other partner schools in NH and VT and finally to any school wishing to adopt them. In addition, A STEM rural educator network, through which crosscutting units may be disseminated and teachers may share and support each other, will be created to enhance the teachers’ ability to network, seek advice, share information, etc.
