That evening, Aiden’s older sister Mia found him playing video games in their shared room.

“How’d the math quiz go today?” she asked.

Aiden shrugged without looking away from the screen. “Not great.”

Mia sat down beside him. “You know, when I was in seventh grade, I struggled with math too. But then I learned something cool in science class about feedback loops.”

“What’s a feedback loop?” Aiden asked, finally pausing his game.

“It’s like a cycle where what happens next depends on what happened before,” Mia explained. “There are two main types: reinforcing loops, which make things increase or decrease more and more over time, and balancing loops, which keep things stable.”

Aiden looked confused, so Mia tried a different approach.

“Think about it like this: right now, you’re in a reinforcing feedback loop, but not a good one. You don’t prepare much for quizzes, so you get low grades. Those low grades make you feel bad about math, so you avoid studying, which leads to more low grades. See how it keeps going around and around?”

Aiden nodded slowly. “So I’m stuck in a negative cycle?”

“For now,” Mia said. “But the awesome thing about feedback loops is that you can change them. What if you created a positive loop instead?”

“How would I do that?”

“Start by changing one part of the cycle,” Mia suggested. “What if you tried studying a little each day next week, instead of not at all?”

Aiden was skeptical but agreed to try. Mia helped him create a simple plan: fifteen minutes of math practice each day after school, with a slightly longer review on Thursday night.

The following Friday, Aiden felt different as Ms. Rivera handed out the quiz. He wasn’t confident exactly, but he wasn’t dreading it either. When he received his paper back with a C, he felt a small surge of satisfaction.

“Hey, that’s improvement!” Mia said when he showed her. “That’s how positive feedback loops begin. Now, what happens next is crucial.”

“What do you mean?” Aiden asked.

“Well, you could stop here and go back to your old habits. Or you could use this improvement as motivation to keep going and maybe study a bit more effectively next week.”

Intrigued by the idea of the feedback loop, Aiden decided to continue. For the next week, he maintained his daily practice but added something new: he wrote down questions about concepts he didn’t understand and asked Ms. Rivera for help during lunch on Wednesday.

The next quiz result? B-.

“See what’s happening?” Mia asked excitedly. “You studied, which led to better grades, which made you feel more confident about math, which motivated you to study more effectively, which led to even better grades! That’s a reinforcing feedback loop working in your favor.”

Aiden started to get excited about the concept. “So if I keep this going, where does it stop? Will I get an A+ eventually?”

“That’s a great question,” Mia said. “Reinforcing loops don’t continue forever in real life. They usually run into limits or trigger balancing loops. For instance, you might reach a point where improving from an A- to an A+ requires way more effort than improving from a D+ to a C. That’s when you’ll need to decide if that extra effort is worth it to you.”

The following week, Aiden added another change to his routine: he joined a study group that met during Thursday lunch. Working with classmates helped him see problems from different angles and made studying more enjoyable.

Friday’s result: B+.

Three weeks after starting his new habits, Aiden noticed something interesting. Studying no longer felt like a chore he had to force himself to do. It had become part of his routine, almost automatic. And math class itself was more engaging now that he could follow along better.

“That’s another aspect of feedback loops,” Mia explained when he mentioned this. “They can create momentum that makes maintaining behaviors easier over time. The positive feelings you get from success make the behaviors that led to that success more likely to continue.”

By the sixth week, Aiden achieved his first A on a Friday quiz. Ms. Rivera even wrote “Excellent improvement!” on his paper.

That evening, Aiden created a chart showing his progress. The upward trend of his grades was clear to see:
Week 1: D+
Week 2: C
Week 3: B-
Week 4: B+
Week 5: B+
Week 6: A

“This visual really shows your positive feedback loop in action,” Mia observed, looking at his chart. “But remember, feedback loops exist in all areas of life, not just grades.”

“Like what?” Aiden asked.

“Like habits, relationships, even saving money,” Mia explained. “For example, each time you save a little money and see your savings grow, you might feel motivated to save more, creating a positive reinforcing loop. Or think about friendships—being kind to someone often leads them to be kind in return, which encourages more kindness from you, and the relationship grows stronger.”

Aiden thought about this for a moment. “I’ve noticed something else too. Now that I’m doing better in math, I’ve started applying some of the same study habits to science, and my grades are improving there too.”

“That’s called a spillover effect,” Mia said. “The positive feedback loop in one area can influence other areas of your life. Pretty cool, right?”

As the semester continued, Aiden maintained his A average in math. There were occasional setbacks—a particularly difficult quiz where he scored lower, or a week when soccer practice took up more time than usual—but he understood now that these were just temporary disruptions to the positive cycle he had created.

By the end of the semester, Aiden had discovered something important: the power to change wasn’t just about willpower or getting lucky. It was about understanding the cycles that shape our experiences and learning how to create positive loops that reinforce the behaviors we want.

“The best thing about understanding feedback loops,” he told his sister one day, “is realizing that small changes can lead to big results if you stick with them long enough to let the cycle build momentum.”

Mia smiled. “Just wait until you learn about systems thinking in science class next year. Your mind will be blown.”

“Systems what?”

“That’s a lesson for another day,” Mia laughed. “One feedback loop at a time.”
