Using Desmos on iPads… for the Algebra 1 EOC STAAR Test… Take 2

This week, our Algebra 1 students took their STAAR End-of-Course exam.  This round marks year 2 of Algebra 1 students being permitted to use both a TI handheld graphing calculator and the Desmos Test Mode iPad app in light of this TEA calculator policy change that went into effect last school year.

An annual tradition for my Math 8 students (who recently experienced year 3 of TI and Desmos Test Mode access for state testing) and now, my Algebra 1 students, is to give a quick 3-question follow-up survey.

I asked three questions:

  • In general, which tool do you prefer?
  • Name a few math lesson topics for which you like using the TI Graphing Calculator more than Desmos Test Mode.
  • Name a few math lesson topics for which you like using Desmos Test Mode more than the TI Graphing Calculator.

Though my Algebra 1 sample size this year is very small (36 students to be exact) this round marks the first time that not a single student answered the first question by saying they prefer the TI calculator…!  This hasn’t necessarily been the case with Math 8 students annually.  You can see their preferences by checking out this post.

Here’s a side-by-side comparison of this year’s Algebra students and last year’s sample size of 49 students.  Additionally, you can check out the unedited and anonymous responses from this year’s Algebra 1 students regarding their favorite concepts to explore using each calculator.

Algebra Calculator Survey Yenca 2016-17

What struck me most was that we’re paying over $100 a pop for a calculator because it can graph stuff, but these students aren’t actually using the TI handheld graphing calculator for that purpose…!

Hands down, these Algebra 1 students use Desmos for graphing, and the TI primarily for quick calculations using the four basic operations.
