Using ‘Desmos’ To Increase Student Interactivity

What challenge, problem or motivation inspired you to make one small change?

When teaching correlation and regression in my statistics class, I was afraid that doing calculations by hand was interfering with students’ understanding of the concepts. I wanted to develop an interactive activity to reinforce students’ understanding of the correlation coefficient and the components of linear equations.

Tell us about your one small change:

This semester, I taught lessons on correlation and regression using Desmos which is a graphing software that also allows teachers to develop activities. Using Desmos allowed all students to experiment with changing the data and the equation of the line. For example, in the past I would ask a few students to share what they thought was the line of best fit by drawing it on the board but with Desmos all students could create a line of best fit and I could share all students’ results/responses with the class live to promote discussion. I could also ask multiple choice and short answer questions for formative assessment using Desmos.

What was the result of your one small change?

At the end of the course, students commented that the Desmos activities were their favorite because these activities helped them to visualize and understand the theories. I was encouraged to try Desmos again next semester!
