• 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

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

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
