1. GPS for Teachers:An Extended Professional Development Program for Geometry Teachers Presenters: Edward Knote & BheshMainali University of Central Florida Mathematics Education PhD. Students

2. Geometry Professional Development Series for Teachers(GPS) University of Central Florida PI: Dr. Janet Andreasen Co-PI: Dr. Erhan S. Haciomeroglu & Dr. Marina Capursi BheshMainali; Edward Knote; A. Zghayyar

3. What is GPS for Teachers? • Funded under Florida Department of Education (FLDOE) Teacher Quality Grants; • Collaborative partnership between UCF College of Education, College of Sciences, Orange County Public Schools (OCPS), and Florida Virtual School (FLVS); • Extensive professional development for High School Geometry teachers in OCPS.

4. Goals of GPS for Teachers • Improve teacher content knowledge in geometry; • Increase student achievement in geometry; • Develop professional development program for sustained and focused support for geometry teachers; • Evaluate professional development.

5. Structure of Professional Development • 40 High School Geometry teachers in each cohort (two cohorts); • First cohort started in summer 2012 completed in summer 2013; • Two weeks of professional development in fall and summer; • Monthly follow-up professional development throughout school year with site visits; • Final week of professional development in summer 2013 for second cohort.

6. Professional Development • Focused on: • Implementing Next Generation Sunshine State Standards (NGSSS) and Common Core State Standards for Mathematics (CCSS-M) along with the Standards for Mathematical Practice (SMP); • Reasoning and sense making • Developing mathematical knowledge for teaching geometry.

7. Constructions • Foster reasoning and sense making and the Standards for Mathematical Practice; • Focus on explanations and justifications; • Connect technology in meaningful ways; • Represent constructions in multiple ways; • Reach diverse learners.

8. Instruction Format • Small Group activities; • Technology training sessions (GeoGebra, iPAD Apps.); • Manipulative exploration through Think Pair Share; • Open forum for sharing experience.

9. Evaluation and Assessment • Regular School visit; • Classroom activities; • Diagnostic mathematics Assessment Test.
