"Why schools fail: a view from a college professor" (Opinion Exchange, Oct. 23) was an enlightening piece. I'd like to pass on my experience with the narrower topic of mathematics in the public schools. I am an engineer and have used math as a tool for decades. Algebra, geometry and trigonometry (A/G/T) were my mainstays.
Though my involvement may be a bit dated, I saw the signs of coming troubles in math education some 30 years ago, when I had the opportunity to help a student from my church with some basic algebra. Word got around and demand increased to the point that I set up a "homework helper" room at home.
That led me into a 25-year "career" of tutoring A/G/T. I was happy that I could help nearly 50 students.
High school math had been hard for me when I was in school. I had to work out alternative methods of doing the math; alternative approaches to framing problems. The advantage this gave me in tutoring was in my unique ways of approaching math problems or visualizing geometric analogues. All these "tricks" stood me well in helping students, many of whom had the same difficulties I did. If they didn't grasp the solution using one explanation, I had alternatives, one of which often worked for them.
It is important to note that the students I worked with were mostly white, suburban kids from affluent neighborhoods. Yet as I started working with these students, one thing became apparent to me. Many could not do arithmetic. I had high school juniors who could not divide by 10 in their heads. They immediately reached for their calculators, even for simple addition or multiplication operations. And these were bright kids.
You can only imagine how reliance on that technology slowed them down in doing their homework. And the error rate in entering numbers was alarming. Furthermore, this was raising their frustration enormously. I realized that by handing students a calculator in fourth grade we were sabotaging their math skills, fostering a dependency on technology. Of course, they had learned their basic math facts and passed tests, but they quickly unlearned them.
As an experiment, I began taking away my students' calculators, demanding they do their basic arithmetic in their heads. After two months of mental math (accompanied by grousing and kvetching) they found they could get their homework done in half the time, more accurately. This became my standard procedure thereafter.
Another thing I focused on was "housekeeping" — laying out succeeding operations in a logical (and neat) array, line by line. To me this was critical in tracking the solution process and, more importantly, being able to backtrack to find the source of errors. This led to more whining, but eventually they saw the benefits of working methodically.
