The marketplace for educational tips and tricks is too new to have generated policies or guidelines in most places. In Fairfax County, Va., officials had been studying the issue when they discovered this fall that a former football coach was selling his playbook and instructional DVDs online for $197; they investigated but let him keep selling.

A high school English teacher in upstate New York said her bosses barred her from selling plans used in her classroom; she spoke on the condition that she not be named.

Beyond the unresolved legal questions, there are philosophical ones. Joseph McDonald, a professor at the Steinhardt School of Culture, Education and Human Development at New York University, said the online selling cheapens what teachers do and undermines efforts to build sites where educators freely exchange ideas and lesson plans.

“Teachers swapping ideas with one another, that’s a great thing,” he said. “But somebody asking 75 cents for a word puzzle reduces the power of the learning community and is ultimately destructive to the profession.”
