Growing up, I felt that I learned some things quickly and other things painfully slowly. Picking up French and Spanish seemed to come naturally, while painting and drawing required a lot of practice. I thought that some people just have a talent for languages; others don't.
You've probably felt the same way—that certain things were easier for you to learn. And so did my research partners. So we set out to identify what makes some people learn faster than others. If we could just distill (提取) these unique characteristics, we thought, we would be able to create better learning environments—and make everyone a fast learner.
In our study, we model data from student performance on groups of tasks that assess the same skill component and that provide follow-up instructions on student errors. Our models estimate the increase in correctness after each practice opportunity. We applied our models to 1.3 million observations across 27 datasets of student interactions with online practice systems in the context of elementary to college courses. In contrast, and much to our surprise, we found students to be astonishingly similar in estimated learning rate. There are no such things as fast and slow learners!
We find that a typical student needs about seven learning opportunities to master a typical knowledge component. They start at different levels of proficiency but, when provided with high-quality practice opportunities, they learn at about the same speed. Yes, they will end in different places-but that's because they have different starting lines, not because they are quicker or slower to learn.
That means the types of opportunities you get are important. Detailed, timely feedback and hints provide favorable conditions that allow you to consistently make progress, regardless of where you began.
Don't think you're alone if learning feels slow and effortful. Do try, try again. You can make as much progress as everyone else—and so can the young people in your life. Achievement gaps are the result of opportunity gaps, not individual differences in learning speed.
