In investigating how much "time and effort" my colleague and I exert when teaching online, we realized that we did not have a clear idea of the difference (if indeed there is a difference.) Any thoughts? When we evaluate our work in industry or the academy, do we mean "time" when we say "effort" or do we mean "time" plus added expenditure of energy or something else? Ideas and thoughts welcome!

BTW, our working hypothesis was that teaching online took more "time and effort" than teaching the same course face-to-face. We found that there is not a statistically significant difference except in one of four categories.
