As mentioned in my previous blog post, there are 94 sessions which emphasize technology’s role in math ed in their sessions. I did an analysis of the grade levels of the talks. In figure 1 note that the most frequent grade level for tech sessions at the NCTM annual this year is in the high school range. If you include the 8-10 range as partially high school you have a total of 56 sessions appropriate for a high school audience.That’s almost 60% of the total. I suspect the conference program committee missed this fact.
