Christopher Vaccaro,Yvette Kisorh indicates that students receive little opportunity to engage in justification activities for various reasons. In this chapter, we sought to describe the justification process that unfolded during one middle-grade classroom lesson and identify elements that supported this process. To do so, we pars

Data from our own project are included to illustrate the possibilities for proof and proving in middle grades. We found that middle-grade students demonstrate some practices associated with proof and proving and recommend exposi

We also discuss the consequences associated with analyzing classroom data of the task’s implementation from the three different perspectives of argumentation, justification, and proof. In the former case, we discuss the possibilities a
