This workshop emphasizes methods for helping students to learn concepts in chemistry from the perspective of systematically developed particle models for matter. The course incorporates up-to-date results of chemistry education research, best practice curriculum materials, use of technology, and experience in collaborative learning and guided inquiry. Instructional strategies include a coherent approach to the role of energy in physical and chemical change.

Meet the Leaders:  

Jesse Braxton

Jesse teaches chemistry and IB chemistry SL at Central High School in Philadelphia, Pennsylvania. He holds a BS in Chemistry and an M.S.Ed in secondary science education, and is also a Senior Fellow with the Knowles Teacher Initiative. Jesse has been teaching using the Modeling Instruction approach to chemistry since completing his first workshop in 2017, first in a school serving mostly high needs students in West Philadelphia and more recently in a college preparatory, public, magnet school. Adapting Modeling pedagogy for the two different student populations with different strengths and needs has been a passion project for Jesse, and he is excited to support other teachers to use it in their classrooms as well. 

Raymond Howanski 
Ray taught high school chemistry and biology for 22 years at Ridley High School in Folsom, PA.. He supported teachers as the Asst. Director of Curriculum and then Director of Curricular Innovation for an additional 13 years at the district level for Ridley. Since 2007 Ray also led Modeling Workshops and professional development in Modeling Instruction throughout the country. Additional work in Modeling Instruction includes contributions to the chemistry resources as well as facilitation of the development of the NGSS Modeling Biology (for a P-C-B sequence). He is now working as the Executive Officer of AMTA to support teachers and promote the use of Modeling Instruction.
