College of Physical and Mathematical Sciences
2011
• Cultivate and diversify the pool of students pursuing degrees and careers in STEM fields.
• Improve the quality of teaching and learning in STEM education.
• Communicate innovative scientific and educational research to the public.
Cultivate. Educate. Innovate.
Science, Technology, Engineering, & Mathematics
Outreach to North Carolina for 20+ Years
2011
What do we do?• S3: Sustained STEM
Support• Teacher Professional
Development• Equipment Loan• Curriculum Development
and Dissemination• FREEDM• IMHOTEP• Photonics Leaders• NC Science Olympiad
2011
S3: Sustained STEM Support
• Partnership with schools to provide long-term PD (1-5 years)
• Customized to your needs• May include needs assessment, PD,
consulting, coaching, modeling and lesson development.
• Focus on “doing” science and math using TPaCK

From each Satellite Office, technology is rotated between K-12 schools in the area for use in Science and Math classrooms.
Demonstration Lessons
Science House Outreach Coordinators assist teachers who wish to incorporate technology into their curriculum with demonstration lessons for their classes.

Why Use Technology???
• Students collect their own data for analysis
• Quick data collection allows for more analysis time and further investigations
• Monitoring several parameters at once allows students to observe relationships
Water Temperature (oC)
Dissolved Oxygen (mg/L)

Temperature
Temperature range: – 40 to 135°C (– 40 to 275°F)
Maximum temperature that the sensor can tolerate without damage: 150°C

Impact on Teachers Increased use of inquiry and
laboratory-based teaching Teachers are forming
collaborative networks and increasing professional involvement
Teachers are leading and teaching other teachers
Schools are investing in more laboratory equipment
Reports of increased science enrollment, higher End-of-Course grades
Impact on Students
Increased student interest in STEM fields
Increased student understanding of concepts
Recruiting of outstanding students for NC State
