Recently, the Smarter Balanced testing group announced that it was embedding the Desmos calculator into its online math assessments-a move that Desmos officials say other major testing companies are considering as well. If you or somebody you know works for PARCC, TestNav, or Pearson and would like to discuss this, please reach out to me.Proponents of hand-held calculators quickly counter that web-based tools are far from cost-free: In addition to purchasing hardware, such as tablets and laptops, schools need to pay for information-technology support and reliable broadband to use those tools.
If PARCC changed its choice of graphing calculator is could be using a better tool, and could save the schools and students its testing money. It is amazing to me that schools and students have to spend around $100 for a graphing calculator, when there is a far better tool for free.

Not only is Desmos a free website, but is also has a free app available for all devices. The cost of these TI calculators is around $100, which seems like a high amount considering that over the last 20 years that haven’t improved their technology much. One of the most frustrating aspects of PARCC’s decision on the graphing calculator is the related cost to the schools and the students.
There are many other benefits to using the Desmos calculator….too many to mention in this forum. In addition the tools and interactions with the equations and graphs are far more intuitive with Desmos. First of all, which one is more visually appealing? Also, I would like to point out that on Desmos you can see both the equation and the graph on the screen, TI it is 2 separate screens. Desmos is a much more intuitive tool to use, has much better resolution, has more features, and also has accessibility features for students who need them.īelow is the graph of the same equation in both Desmos and using the TI calculator provided on PARCC. This is calculator is very similar to the graphing calculator I used in high school and college over 20 years ago….still featuring all those amazing pixels!! Why would PARCC choose this calculator? There are several online graphing calculators that are far superior to the one offered on the PARCC, my favorite being Desmos.

The graphing calculator offered to them is a TI – 84 plus silver edition . During the exam the students have an embedded graphing calculator available to them, and this is where my objection occurs. In NJ passing this exam is a graduation requirement, which adds another level of stress and importance to the exam. The majority of my students are in Algebra 1, therefore they take the Algebra 1 PARCC exam. Regardless of my thought, it is a test my students have to take, and although I don’t “teach to the test”, I do try to give my students tools they need to succeed in their math classes in the future and also on any standardized test they may cross during the educational journey. In this post I am going to refrain from my opinions of the actual test, but I will quickly mention that I understand both sides of the debate about the test. I am a teacher in the state of NJ, where we currently give the PARCC exam (although our new governor says we are going to move away from it.
