三．阅读理解

A

A few years ago, I stood in a small classroom, watching a high schooler named Serena Stevenson answer math questions. An instructor read out numbers—7447, 7089, 9842—and Stevenson added them in her head. For each question, she closed her eyes, and then the fingers of her right hand began to move. She answered most of the problems correctly.

The key to her success was an ancient technology called the abacus(算盘). For much of that evening, Stevenson used a practice called “mental abacus”， imagining the abacus in her mind and then using her fingers to work through the problem.

From watching Stevenson, I knew that gaining skills on the abacus was more than a matter of counting beads(珠子), so I decided to sign up for an abacus course with my two daughters to see if we could also improve our math skills. I was one of the many who harbored some math doubts and I felt a touch of fear of math. My typical solution was avoidance, and if I had to calculate something like percentage change, I would go online.

Then after a few abacus classes—and a good amount of practice—math seemed a

little less frightening. I hadn’t become Euclid. But the practice brought my numerical fears down a level. This is a long－demonstrated power of the abacus. Confidence grows easily on the device, and abacus students are less likely to be nervous about an upcoming math test, according to one study. Part of the reason, it seems, is that practice and outcomes appear to move in step, with hard work correlating(和……相关) highly with performance.

My kids had gained some math confidence as well. My youngest daughter would beam broadly after getting a math problem correct, while my older child brought her abacus to school to show to her classmates and teacher. These were small successes. But that’s how they ultimately develop confidence.
