What is STEM?

STEM Education is an approach to teaching and lifelong learning that emphasizes the natural interconnectedness of the four separate STEM disciplines. The common element of problem solving is emphasized across all STEM disciplines allowing students to discover, explore, and apply critical thinking skills as they learn.

A River Greenway: A Community STEM Project
The Grande Ronde River once meandered through the large horst graben Grande Ronde Valley  in north east Oregon with oxbows much like that of the current path of Catherine Creek ( See the above photo).   In the late 1860’s a large loop of the Grande Ronde River was ditched to drain land for agriculture and to protect some residential and business developments from seasonal flooding.  To assist in logging, river was also dammed to the west, filled with floating logs and then each spring the dams would be exploded so logs would careen down the river gouging everything in their path. During the mid 20th century and up until the 1980’s the ditch or canal was mined for its sand and gravel.  As the years passed the canal deepened from the effects of mining causing steep banks and the need for reinforcements on the margins. For many years the river seemed sterile–a causeway for commerce.

Even though assailed by progress and abuse, the river survived.  With the advent of protective inland waters legislation the river has started to recover showing a great deal of beauty and aesthetic appeal.  Wildlife clings to the riparian areas along its banks and fishermen and hikers enjoy poking about on the margins. Riverside Park, in La Grande, borders the river to the west. The city has installed a short trail section near the river and a bridge that allows walkers and bikers to enjoy the vista from mid stream. Island City, about a mile down river to the east, plans to create another park similar to Riverside and to connect their park to La Grande’s with a Greenway.  City and county officials have secured some funds to pay for infrastructure and have drawn-up ideas about how the trail might hug the river from La Grande to Island City. How then is this a Community STEM challenge you might ask?

The Grand Ronde River, like any waterway, is a natural ecosystem that can be impacted by human intervention. Aquatic creatures and the riparian areas can be altered, damaged, or ruined. Understanding the science of the river system, the plants and animals, the water ebb and flow, and the riparian ecosystem becomes a critical part of understanding the river and concern for a human pathway.  Impact analyses, reports and permits are required to assess the scientific impact of the project.

Engineers examined the planned route and then calculated the amount and kind of fill necessary, the make-up of the potential project bridge, and the composition and preparation for the path itself. The engineers alone could not conduct this work without considering the aesthetics, safety, legality, and utility of their design. Engineers must also consider the kind of materials and different technology available to solve specific problems: Whether to use metal netting to contain bank stabilizing riprap, the materials to be considered for a bridge and the long-term considerations for maintenance, and whether pre-fabricated, elevated concrete walkways may solve certain problems when placing the trail near the water.

Finally, the Greenway committee had to deal with the overall applied mathematics of the project. What were the features of each option and how would the committee recommend one route over another?  Surveys, rating systems, and statistical analyses were required to help bring the best solution forward. And, almost the most important variable, what were the costs associated with the project?  Careful prediction of cost per square foot of trail and each additional feature required had to be computed.

Of course, the STEM disciplines only provided the background facts.  The city, county and State officials and landowners still have to consider property owners, easements, land use restrictions, and other technical matters.  The Greenway project is a real example of how STEM professionals inform and shape problem solving within a meaningful context. It is the kind of critical thinking we hope our students will do and the kind of learning we expect as they acquire knowledge and skills in the STEM disciplines.

What are you doing in your classrooms, schools or communities to get students involved with real individual, classroom, school, or community projects?  Tell us your story.  Let’s help each other design meaningful STEM explorations where students can make a difference.

 

 

What is a STEM Hub?

Oregon STEM Hubs are a Strategic Initiative overseen by Oregon’s STEM Investment Council and the Chief Education Office to increase student interest, preparation, and attainment in science, technology, engineering, and mathematics for success in related degrees and careers. These regionally-focused, multi-sector partnerships unite schools, institutions of higher education, non-profits, businesses, civic leaders and communities to drive local STEM innovation and improvements at the systems-level, while also working to identify systemic barriers and co-construct solutions with communities most affected by the barriers. The STEM Hubs leverage local resouces and opportunities to bring STEM to students early and often, engaging them in and beyond the classroom. Hub borders are fluid, overlapping into surrounding communities and connected by multiple professional networks through which ideas and resources flow.  Regional STEM Hubs form a mutually supportive statewide network of hubs for implementation and dissemination of best practices.

Collective Impact Partnerships

The Theory of Action for the Regional STEM Hub strategy is based upon a collective impact partnership model where partnerships engage with multiple sectors in the community; eliminate locally defined inequities; use data for continuous improvement; and leverage community assets in efforts to improve practice and increase opportunities related to STEM education. Hubs align partner efforts towards a common agenda with a commitment to using relevant data for continuous improvement. Where regional programming gaps exist, STEM Hubs also implement strategies that include:

  • educator professional development around best practices in STEM instruction,
  • implementation of the Next Generation Science Standards and the Common Core,
  • increasing in and out of school hands-on STEM learning experiences for students, and
  • deepening student connections to the fast-growing STEM employment opportunities in the state of Oregon.
