I think the most significant argument for going to simulated dissections of frogs lies in the reality of a global amphibian decline. This, unfortunately, includes Rana pipiens (sensu lato). As a science department head of a high school in Texas, I definitely encourage--not require--my teachers to go the simulation route (also, it saves money!).
Thinking back, I can still remember the first time I dissected a real frog. But, then, I was into herps. I'm not so sure that my contemporaries got the same educational worth from it--beyond the gross-out value of pithing and "cutting up" the poor amphibian!
Collection of amphibians from the wild merely for use in primary and secondary school "dissections" is nowadays hard to justify--except perhaps for Bullfrogs from areas into which they have been introduced!
