Pre-service and in-service teachers need more preparation for online and blended learning due to increased use during the pandemic. Only 1.3-4.1% of US teacher programs and 32% of Canadian programs previously provided experience in online schools. Recommendations include sufficient coursework, field experiences in online settings, research-based standards, experience as online learners, assessment of growth, and requirements for meaningful preparation in online and blended learning. Without proper preparation, learning continuity could be lost as it was during the 1918 Spanish Flu when some Canadian students missed 13-14 weeks of school with no learning.
