Reflection: Developing a Conceptual Understanding The Drawbridge - An Introduction to Inverse Sine - Section 1: Launch and Explore


Trigonometric inverses are always tough for students, but I was very happy to see that my students were making sense of inverses. This student understood how to set up an equation with sin(y) = x/43, but was unable to solve the equation for y.

This student may not have been able to solve for y, but this roadblock made him realize that he needed an additional tool that he did not have yet. Thus, he was presented with a context where an inverse trig function makes sense rather than me just explaining this function in a lecture format.

It is much easier to just give students the information that they need, but grappling with contexts really builds the important conceptual understanding.
