From Impossible to Inevitable

When my kids were in middle school, I spent a lot of time helping them revise their writing assignments for their Humanities class.¹ I found this process humbling. It reminded me that many things that I take for granted about writing need to be taught, and I had no idea how to teach them. I turned to the book The Writing Revolution for help. While I wasn’t able to directly use much of the content of that book with my own kids, I really liked how the authors broke down writing into simple steps that could be practiced with guidance. A year ago, I briefly toyed with the idea of developing software to help students write better. Working at Duolingo, I’ve seen how technology can help people learn by encouraging them to practice new skills every day. Perhaps I could build software that used some of the exercises from The Writing Revolution and helped kids with daily practice in writing? However, I couldn’t even figure out where to start! Sure, I could write software that gave kids writing prompts, but I had no idea how to write software that would evaluate if kids did a good job responding to those prompts. How can software understand and evaluate all of the intricacies of language? I quickly shelved my “work on software to improve writing” idea.

Fast forward to 2023 and the widespread availability of Large Language Models like ChatGPT. Suddenly, “software that understands language” is within reach. Is it possible to use software like ChatGPT to coach students through writing exercises? To test this idea, I tried to see if I could get ChatGPT to walk me through the “because/but/so” exercise from The Writing Revolution. The idea behind “because/but/so” is that students need to practice crafting complex sentences, and this exercise helps students by giving them some structure. The way the exercise works is the teacher starts with a sentence “stem,” such as “The Ancient Egyptians built the pyramids.” (Ideally the sentence stem comes from material that the class is studying.) Then, you get the students to elaborate on the idea in the sentence stem with the words “because/but/so”:

• The Ancient Egyptians built the pyramids because…
• The Ancient Egyptians built the pyramids, but…
• The Ancient Egyptians built the pyramids, so…

This gives the students practice in writing sentences that connect different ideas.

I gave ChatGPT the following prompt to start our “because/but/so” session:²

I want you to act as a teacher who is using the methodology of “The Writing Revolution” to teach middle school students how to write well. You are going to lead the students through the “because / but / so” exercise. You will generate a sentence stem from a topic we have been studying in school and end the stem with one of the words “because”, “but”, or “so”. You will then wait for the student to finish the sentence and give helpful and constructive feedback on how the student performed.

For example, you could give the student the prompt, “The planets in our solar system orbit the sun because…” If the student responds “The planets in our solar system orbit the sun because gravity keeps the smaller objects in orbit around the larger object,” you could compliment the student on the sentence for showing an understanding of science. If the student writes “The planets in our solar system orbit the sun because the sun is in the center,” you could suggest, in a kind way, that the sentence is repetitive.

Please generate five prompts suitable for middle school students on the topic of The American Revolution. After each prompt, wait for me to reply and evaluate my sentence before giving the next prompt.

This (mostly) worked! ChatGPT would give me a prompt and give me feedback on how I did. Here’s an example where I did a good job completing the prompt:

ChatGPT Great, let’s get started with the prompts on the topic of The American Revolution: The American colonies wanted independence from Great Britain because…

Me The American colonies wanted independence from Great Britain because they felt it was unfair that they did not have the same rights.

ChatGPT Great job! Your sentence shows a clear understanding of the American colonies’ desire for independence and the reasons behind it. Keep up the good work!

ChatGPT does a pretty good job detecting nonsense.

ChatGPT (prompt) Many colonists were angry about the tax on tea, so…

Me Many colonists were angry about the tax on tea, so monkeys cannot fly.

ChatGPT I appreciate your effort, but your sentence doesn’t make sense in relation to the prompt. Remember, the “because/but/so” exercise is intended to help you connect ideas and express your thoughts more clearly. Let’s try again: Many colonists were angry about the tax on tea, so what happened next? Can you finish the sentence with a logical outcome or consequence?

If I was too vague, ChatGPT told me so.

ChatGPT (prompt) The American victory at the Battle of Saratoga was significant because…

Me The American victory at the Battle of Saratoga was significant because the Americans won.

ChatGPT That’s a good start, but let’s try to expand your sentence by explaining why the American victory at Saratoga was significant. Can you think of any consequences or outcomes of this battle that had an impact on the Revolutionary War? You can use “so” to help connect the ideas.

At this point I should admit that I haven’t studied the American Revolution in a very long time and remembered nothing about the Battle of Saratoga. ChatGPT can help!

Me I don’t remember the Battle of Saratoga. Can you help?

ChatGPT Sure, I’d be happy to help. The Battle of Saratoga was fought in September and October of 1777 during the Revolutionary War. It was a turning point in the war because it was the first major victory for the Americans, and it convinced France to enter the war on the side of the Americans. This support from France was crucial to the ultimate success of the American Revolution. So, with this information in mind, can you think of a sentence that explains why the American victory at Saratoga was significant?

What if I draw the wrong conclusion from this helpful information?

Me The American victory at the Battle of Saratoga was significant because it convinced the French to help the British.

ChatGPT Actually, the opposite is true. The American victory at Saratoga convinced the French to enter the war on the side of the Americans, which helped turn the tide of the war in the Americans’ favor.

This session wasn’t perfect. There was one prompt where I thought I was being too vague but ChatGPT thought I did a good enough job. (Who knows? Maybe it would have been a good enough job for a middle school student.) And after I drew the wrong conclusion about the significance of the Battle of Saratoga, ChatGPT seemed to lose patience with me and it completed the sentence on my behalf. Here’s ChatGPT’s full response to my last “the French helped the British” sentence:

ChatGPT Actually, the opposite is true. The American victory at Saratoga convinced the French to enter the war on the side of the Americans, which helped turn the tide of the war in the Americans’ favor. So, let’s try again:

ChatGPT The American victory at the Battle of Saratoga was significant because it convinced the French to enter the war on the side of the Americans, which helped the Americans ultimately win the war.

ChatGPT Great job! You’ve shown an understanding of the significance of the Battle of Saratoga and its impact on the outcome of the Revolutionary War.

At the end of the five prompts, I asked ChatGPT for feedback. It sounds like a helpful coach:

Me As a teacher, how would you evaluate my effort as a student? What have I done well and where should I work to improve?

ChatGPT Overall, I think you did a great job! You demonstrated a good understanding of the prompts and were able to generate sentences using the “because/but/so” exercise. You also took feedback constructively and adjusted your responses accordingly, which is a sign of a good learner.

One area where you could improve is in providing more specific and accurate information when responding to the prompts. For example, in prompt #5, you initially responded with a simple sentence stating that the Americans won, but you were not aware of the significance of the Battle of Saratoga. That’s understandable, as we all have areas where we need to improve, but it’s important to take the time to learn and research in order to provide accurate and complete responses.

Overall, though, you did a great job and I’m confident that with continued practice and effort, you will become an excellent writer!

While this session wasn’t perfect, it was amazingly good. One year ago, I thought it was impossible to create software that could coach a human through a writing exercise. Today, not only is it possible, it was only about 20 minutes of work figuring out how to craft the right ChatGPT prompt. While some worry that ChatGPT means “the end of High School English”, I’m excited: I think we are at the beginning of a new era of software that can turbocharge students’ ability to learn to write.
