Samuel Otten from the University of Missouri discusses the article "Univocal and dialogic discourse in secondary mathematics classrooms: The case of attending to precision," published in ZDM - The International Journal on Mathematics Education, Volume 47. (Co-authors: Chris Engledowl and Vickie Spain)

The concluding music is "The Highway" by Samuel Otten, based on the short story by Ray Bradbury. And on Sam's list of favorite TV shows, the third slot will sometimes go to Modern Family over Breaking Bad depending on the time of year.
