Not All Opportunities to Prove Are the Same
Gilbertson, Nicholas J.; Otten, Samuel; Males, Lorraine M.; Clark, D. Lee
Mathematics Teacher, v107 n2 p138-142 Sep 2013
Confusion can arise from the subtle difference between proving a general and a particular statement, especially when general statements are presented by textbooks in ways that make them appear particular in nature. The authors discuss the implications for teaching proof in light of the current opportunities in high school geometry textbooks.
