How we made this book
A fictional story. This story is based on SM’s journey with AI. St. Brigid School and everyone in it are made up. The bumps and the lessons are real.
Who did what. Michelle Cho and Jorge Ledezma chose the story, wrote the character sheets and picture descriptions, directed and approved every change, and checked the facts against SM’s documents. Claude, an AI model made by Anthropic, drafted and revised the words from our notes. Gemini, an AI image model made by Google, generated every picture; none were drawn by hand. When a picture was wrong, we asked for a new one.
Our AI use level: AI-Enhanced. Using SM’s faculty AI guidelines, we place this book at AI-Enhanced: part of the content was generated by AI, and we disclose it. The cover names Claude as a co-writer; in a formal citation, AI is cited as a tool, not an author.
We take responsibility. We are responsible for everything in this book, including the parts made with AI.

For every SM student
still learning to do the walking.
One day, a lantern came to St. Brigid School. It glowed, and it could make things. If you told it what you wanted, it made it. A poem. A picture. A whole story! The kids found out first. The grown-ups did not know what to think.
1
Miguel wanted to give his grandma a poem. So he asked the lantern. Whoosh! It wrote one, fast and fancy. "Did you write this?" Grandma asked. Miguel looked at his shoes. "The lantern did." Grandma hugged him anyway. But Miguel felt funny inside. The words were pretty. They were not his words.
2
The grown-ups got worried. They hung up a big sign: NO LANTERNS! But lanterns still glowed at home. And nobody had learned how to use one well. The sign said NO. It did not say HOW.
3
A visitor brought a machine called the Sniffer. "It beeps when kids use the lantern," he said. Beep! Beep! It beeped at Ava's story about a fox. But Ava wrote that story herself! Ava cried. Her mom and dad were upset. "A beep is not the whole truth," said Mrs. Ortega, the principal. "We will talk with our kids first."
4
"I cannot fix this alone," said Mrs. Ortega. So she asked for help. Teachers, kids, moms, dads, and Father Tom sat in a circle under the big oak tree. Everyone got a turn to talk. "Let's stop saying NO," said Mrs. Ortega. "Let's start learning to KNOW."
5
Every class is different. So each teacher hung a sign with three colors. Green: the lantern can help. Yellow: ask first. Red: this one is all yours. Now everyone knew the rules, one room at a time.
6
On Thursdays, the teachers ate lunch and learned together. Mr. Lee asked the lantern about Saint Brigid. "She rode a dragon to school," it said. Everyone laughed. That was not true! So they looked it up in a real book. Now they always check what the lantern says. All summer, they changed their lessons, so the work asks kids to think.
7
The kids had an idea of their own. "Don't try to catch us," they said. "Trust us." So they wrote a promise: My work shows my own effort. I follow my teacher's lantern rules. I tell the truth about my helpers. "Trust is the glue that holds us together," said Ava. Promise Keepers helped everyone remember.
8
The promise went on every paper, every day. Soon Miguel signed it without even reading it. Scribble, scribble. Mr. Lee noticed. "Read it out loud, Miguel," he said. Miguel read it slowly. His cheeks got warm. "A promise only counts," said Mr. Lee, "if you mean it."
9
One day Ava crossed her arms. "Just tell me what to write!" Mr. Lee knelt down beside her. He did not give her the answer. "The hard part is where your brain grows," he said. "The lantern can light the path. But your feet have to walk it." Ava stayed in at recess. She tried, and tried again. Then she got it. All by herself.
10
After school, the teachers spread the kids' work across one big table. They held up the lantern, and its light helped them see. Five kids were stuck on the same step! The next day, Mr. Lee taught that step a new way. The lantern did not do the kids' work. It helped the teachers help the kids.
11
Father Tom told a story from the Bible. "Long ago, people built a tall tower to make a big name for themselves. They stopped understanding each other, and they never finished it. But God's people build a city together, where God is at home with us. Here, we build that city in each of you. We grow the whole you: your heart, your mind, and your soul. Your heart is the ground. Without it, nothing else can stand. A lantern can build a tower fast. It cannot grow a person." "Let's build the city," said Miguel.
12
Miguel wrote a new poem for Grandma. It was short. It was a little messy. And every word was his. Grandma read it twice. Then she hugged him tight. On the shelf, the lantern glowed softly. It was a helper, not the boss.
13
Under the oak, the whole school kept building, one brick at a time. "Are we done?" asked Ava. Mrs. Ortega smiled. "Not yet. We are still building." The lantern can light the way. But you have to do the walking.

The End
Turn the page for grown-ups.
For grown-ups: what each piece stands for
| The lantern | Generative AI tools (ChatGPT arrived November 2022; students knew before staff) |
|---|---|
| The big NO sign | The first AI policy (March 2023): AI banned unless explicitly allowed |
| The Sniffer | AI detection tools (Turnitin, CopyLeaks). After parent concerns about accuracy, the school relied on them less; detectors are never the sole deciding factor |
| The Oak Table | The Innovation Taskforce: administrators, teachers, students and parents. "We moved from NO to KNOW" |
| Three colors | The stoplight model: instructors may prohibit, manage or encourage AI use for each course and assignment |
For grown-ups (continued)
| Thursday lunches, the dragon, the summer | AI Thursday, Lunch and Learns and Tech Mentors; hallucinations, the early blind spot ("That cost us later"); the Summer Innovation Lab |
|---|---|
| The promise, Promise Keepers | The student-adopted Honor Code Pledge (January 2026) and Honor Reps. "Trust is the glue that binds a learning community together"; the Honor Code is one of the "first steps" on the path to human formation |
| Just a scribble | A pledge on every assignment can become a habit; it has to be talked about to mean something |
| "The hard part" | Productive struggle instead of "doing school" |
| The lantern's best job | The PLC portal: teachers using AI to look at student work together and respond as a community |
For grown-ups (continued)
| Two ways to build | Pope Leo XIV, Magnifica Humanitas (2026): "constructing Babel or rebuilding Jerusalem" (Genesis 11; Revelation 21) |
|---|---|
| Heart, mind and soul | SM's whole-person formation, "Forming the Whole Human Person to live out Caritas Christi": human, intellectual and spiritual formation build on one another; "Without a solid human formation, a student's intellectual and spiritual growth can be hindered" |
| Still building | Our AI journey is still unfolding |
The lantern can light the way.
But you have to do the walking.
