A change in technical education requirements has high school students benefiting from a new approach to math.
The unending strings of numbers, letters and symbols seemed pointless to Devin Johnson. “I couldn’t apply anything that I was learning,” said Johnson, a senior who studies automotive technologies.
Instead of giving up, Johnson persevered, through four years of math classes. Arizona requires all high school students to take four years of math, even if they are not going to college.
Fortunately for Johnson, his district Marana Unified will offer new special math classes focusing on advance concepts, and applying the concepts in auto mechanics. A typical problem: “Find the airflow for a six-cylinder Aston Martin with a bore of 91.0 mm and stroke of 83 mm when it is idling at 860 rpm and the throttle is open 16 percent with 87 percent volumetric efficiency.”
