Why I switched from the TI 83/84 to StatCrunch, and why I am not going back
Like many instructors, I spent years using and teaching with the TI-83 and TI-84 Plus calculators. These devices were considered the standard in classrooms across the country. They were reliable, widely available, and supported by nearly every textbook publisher. For a long time, I had no reason to question whether they were still the best tools for the job.
That changed when my courses transitioned to fully online instruction, and I began using Honorlock to proctor my exams. The issue was not the calculator itself. The real issue was what was hidden from my view when students were using the calculator. During testing, students were often looking down, out of sight of the webcam for long periods of time. I could see their faces but not their hands or their work. From an academic integrity standpoint, this was a major problem. I had no clear way to verify what was happening just below the webcam frame.
As someone who takes academic honesty seriously, I knew I had to make a change. That change came in the form of StatCrunch.
At first, the move to StatCrunch was driven entirely by concerns about exam integrity. Because StatCrunch is accessed directly through the testing screen, students no longer had to look down or shift their focus off screen. It kept their attention on the test and within view of the webcam. This single adjustment immediately improved my ability to monitor exams and reduced the risk of students accessing unauthorized tools or materials.
An improved student experience
Exam security was a primary need. To my surprise, I found that students reported higher satisfaction with the platform. They liked that they did not have to memorize sequences of calculator key presses to run a basic statistical test. They appreciated the cleaner interface and the ability to work directly with real data sets. Many students, even those with prior experience using graphing calculators, found StatCrunch to be more intuitive and less intimidating.
Another unexpected benefit was that test completion times dropped significantly. Students were no longer slowed down by the mechanics of navigating multi-step commands on the calculator. They could get results quickly and focus more energy on interpreting those results correctly. That, in turn, allowed me to shift more of my instruction toward critical thinking. Instead of spending large portions of class time explaining how to find a confidence interval using a series of keystrokes, I could focus on what a confidence interval means, how to explain it in plain language, and how to make decisions based on the output.
It also allowed me to stop teaching students how to use a calculator that was never really designed for statistics in the first place. The TI-83 and TI-84 are graphing calculators with a few statistical functions layered on top. Some of the features I needed had to come in the form of downloaded programs, which was a logistical challenge in any classroom medium. StatCrunch, by contrast, was built from the ground up for data analysis.
This experience even prompted me to rethink my approach in other courses, such as College Algebra. Once I saw how much more efficient and transparent things became using modern tools like StatCrunch, I started reevaluating my use of the TI calculators more broadly. That led me to explore Desmos and other platforms that provide powerful visualizations and eliminate the need to teach around the limitations of outdated hardware. What began as a change for one course evolved into a shift in my overall philosophy of technology in math instruction.
Far-reaching benefits
In hindsight, I regret not making this switch sooner. What started as a fix for one problem ended up solving many others. It improved the integrity of my exams, boosted student engagement, reduced confusion, and created more space in my course for meaningful learning.
There will always be a place for the TI calculator in some classrooms, especially where testing environments and course goals are different. But for online instruction, especially when paired with remote proctoring, I have no hesitation in saying that StatCrunch has become the right tool for the job.
And I am not going back.
