Why STEM Marin?

The United States has become a global leader, in large part, through the genius and hard work of its scientists, engineers and innovators. Yet today, that position is threatened as comparatively few American students pursue expertise in the fields of science, technology, engineering and mathematics (STEM)—and by an inadequate pipeline of teachers skilled in those subjects.

STEM education is a sequence of courses or program of study that prepares students, including underrepresented groups for:

  • successful employment, post-secondary education, or both that might require different and more technically sophisticated knowledge, including the application of mathematics and science skills and concepts.

  • life as competent, capable citizens in today’s technology-dependent, democratic society.

Our Core Beliefs

At STEM Marin, we believe students should develop:

  • Learning and Innovation skills—including critical thinking and problem-solving; creativity and innovation; and communication and collaboration

  • Digital Literacy skills—including information literacy, media literacy, and information and communication technologies

  • Career and Life skills—including flexibility and adaptability; initiative and self-direction; social and cross-cultural interaction; productivity and accountability; and leadership and responsibility

STEM Marin develops these skills through:

  • Authentic learning—learning from real-world problems and questions

  • Model building—using physical and virtual models to refine understanding

  • Internal motivation—identifying and employing positive emotional connections in learning

  • Multi-modal learning—applying multiple learning methods for diverse learning styles

  • Social learning—using the power of social interaction to improve learning impact

  • International learning—using the global world around us to inform and enhance teaching and learning skills
