Department of Physical Sciences and Engineering
Prince George's Community College
Largo, MD 20774-2199
Professor and Chair of Physical Sciences and Engineering
Appointed member of Calvert County Environmental Commission
Modeling and Visualization Workshop
leader for high school teachers through the
Maryland Virtual High School
including co-developer of
Supercomputing Center CAST Professional Development Program modules
for Computational Reasoning in High School Science and Math.
The introduction of guided-inquiry based activities into chemistry, materials science (partnering with Josh Halpern at Howard University), and Earth/space sciences using technology as an enhancement tool for learner-based instruction. Recent efforts involve the development of interactive Excel spreadsheets or Excelets to enhance conceptual understanding via mathematical modeling of data, multivariable simulations, and error analysis. We have also started to have students use Google Drive spreadsheets to develop online collaboration and computational skills.
