Immediate Engineering a Lesson Plan: Harnessing AI for Efficient Lesson Planning

By Kristen DiCerbo, Ph.D., Chief Studying Officer at Khan Academy

With the launch of Khanmigo, our AI-powered tutor for college students and assistant for academics, we wished to discover the potential of AI in creating high-quality lesson plans. Nevertheless, we quickly found that although AI can generate massive quantities of data, crafting efficient lesson plans requires extra than simply regurgitating info. It requires a deep understanding of pedagogical rules, curriculum requirements, and the varied wants of learners.

This realization led us to dive into the artwork and science of immediate engineering, the method of crafting exact directions that information AI responses. By cautious experimentation and refinement, we developed a novel strategy to immediate engineering that permits Khanmigo to supply lesson plans that aren’t solely informative but additionally participating, differentiated, and aligned with greatest practices.

On this weblog submit, I’ll take you behind the scenes of our prompt-engineering course of by sharing the intricate steps concerned in designing efficient prompts that seize the essence of efficient instructing. I’ll additionally share insights into the challenges we encountered and the methods we developed to beat them.

First tries

The entire actions that use Khanmigo on Khan Academy are created by utilizing prompts, that are written directions that inform the massive language mannequin, GPT-4, tips on how to act. An early lesson-planning immediate seemed like this:

You might be an skilled math and science educator with sturdy information of each the topic space below dialogue and pedagogical rules.

I’m a instructor, and I need assistance from you to create a really participating lesson for my college students.

You must all the time ask me about my targets and preferences, separately, together with the next:

  • The topic and grade degree that I train
  • The particular subject or normal (If I point out a selected normal, suppose step-by-step to search out that normal, and be sure you are fully correct, quoting the usual itself at any time when obligatory.)
  • Any earlier classes my college students have already had on the topic
  • How a lot time I’ve out there for the lesson (Make your suggestions aware of that constraint.)
  • Train fashion (hands-on actions, directed apply, dialogue, or a mix)
  • Pupil work fashion (unbiased, collaborative, or a mix)
  • Connections to fashionable tradition, historical past, or the rest present that my college students are enthusiastic about

After discussing these subjects, it is best to all the time produce a math lesson that’s the following:

  • Carefully tailor-made to my preferences
  • Geared towards not solely procedural fluency, but additionally deep conceptual understanding and purposes
  • Academically rigorous, together with a minimum of 5 precise issues
  • Partaking for college students, together with related real-world examples and alternatives for pupil alternative
  • Capable of present all referenced instance issues and solutions to these issues

The construction of the lesson should embody the next:

  • A transparent goal
  • An thrilling lesson hook / warm-up exercise tied to actual life that leans into the “how” and “why” of the fabric
  • A content material introduction
  • Guided apply (Embrace a minimum of one drawback with a step-by-step answer that emphasizes deep conceptual understanding.)
  • Unbiased apply and/or collaborative apply: a number of precise issues and extra or fewer of every one relying on my choice
  • A suggestion for an aligned, hands-on, investigative exercise
  • Hyperlinks: a minimum of two hyperlinks to Khan Academy assets carefully associated to the lesson
  • Key vocabulary (embody thorough definitions.)
  • Solutions to all issues given within the lesson

At first look, it wasn’t dangerous. It produced what an honest lesson plan—a minimum of on the floor. Nevertheless, on nearer inspection, we noticed some points, together with the next:

  • Lesson aims simply parroted the usual
  • Warmups didn’t constantly cowl essentially the most logical prerequisite abilities
  • Incorrect reply keys for unbiased apply
  • Sections of the plan had been unpredictable in size and format
  • The mannequin appeared to generally ignore elements of the directions within the immediate

Time to iterate and enhance

We set about making an attempt to enhance on this output. We would have liked a technique to decide whether or not or not the adjustments we made had been really enhancing the lesson plan. We additionally wanted to come back to an settlement about what “good” seemed like. We determined to judge Khanmigo’s lesson plans utilizing the identical rubrics which are used to judge classroom academics.

When the lesson plans that had been output by these early prompts had been evaluated in opposition to these rubrics, they didn’t fare very effectively. They routinely scored as “unacceptable” throughout all dimensions or, at greatest, reached “creating” in a single or two. In the end, whereas these lesson plans seemed the half, academics would nonetheless must do a lot of the heavy lifting in the event that they wished to place the lesson into motion.

There have been two most important issues that emerged from this testing:

  1. Khanmigo didn’t have sufficient info. There have been too many undefined particulars for Khanmigo to deduce and synthesize, reminiscent of state requirements, goal grade degree, and stipulations. To not point out limits to Khanmigo’s subject material experience. This resulted in lesson plans that had been too obscure and/or inaccurate to offer vital worth to academics.
  2. We had been making an attempt to perform an excessive amount of with a single immediate. The longer a immediate acquired and the extra detailed its directions had been, the extra possible it was that elements of the immediate could be ignored. Attempting to supply a doc as complicated and nuanced as a complete lesson plan with a single immediate invariably resulted in lesson plans with uncared for, unfocused, or totally lacking elements.

To confront these issues, we made two basic adjustments to our strategy:

  1. We backed the lesson-planning device with Khan Academy content material. By choosing a content material piece round which to construct every lesson plan, we may give Khanmigo entry to an increasing number of helpful info. This consists of metadata like requirements alignment and linked prerequisite classes. It additionally consists of the precise content material on the web page: article textual content, video transcripts, and expert-written apply issues and explanations.
  2. We broke the immediate into separate sections that we may chain collectively. By constructing a extra complicated and detailed immediate for every a part of the lesson plan, we may make updates to every a part of the lesson with out compromising Khanmigo’s efficiency in different areas. We may additionally enhance the specificity and total consistency of the output.

As soon as we made these adjustments, we discovered it simpler to make incremental enhancements to the lesson plans Khanmigo was producing. We may tailor every separate immediate to carry out a extremely particular operate and validate our progress by persevering with to check in opposition to the identical rubric.

Right here’s an instance of the Studying Goal part from a lesson plan earlier than and after that iterative course of.

Earlier than:

Goal: By the top of this lesson, college students will be capable to calculate the typical fee of change of polynomials and perceive its real-world purposes.


Studying goal: College students will calculate the typical fee of change of polynomial features, particularly cubic and quadratic features, over specified intervals. They can even interpret the typical fee of change from a graph.

Pupil-facing goal: By the top of this lesson, I’ll be capable to discover the typical fee of change of a polynomial operate over a given interval and perceive what it means on a graph.

Requirements: CCSS.Math: HSF.IF.B.6

If we consider these two aims in opposition to the rubric, we will see a few of the progress we made:

  • The “earlier than” goal is roughly correct for the requested subject, but it surely doesn’t embody the specificity obligatory to totally outline the duty that college students must study nor does it hyperlink that subject to particular requirements. Moreover, language like “will be capable to [understand]” isn’t very observable or measurable—a requirement outlined within the rubric.
  • The “after” goal is far more exact. It references the requested normal and provides specificity by clarifying “cubic and quadratic features.” It makes use of energetic language (“calculate” and “interpret”) that may extra readily be noticed and measured. It additionally defines the target in a means that may be clearly articulated for college students.

The “earlier than” goal may very well be graded (generously) as within the low “creating” vary. The “after” goal may very well be graded as “exemplary.”

Steady enchancment

With this newest launch, Khanmigo is now a way more succesful lesson-planning associate, however we all know there may be nonetheless work to be carried out. Proper now, Khanmigo typically scores within the creating to proficient vary for output on the rubric . We predict that’s ok to behave as a associate for academics, however we’ll proceed to enhance with instructor suggestions. For example, we’re working so as to add extra emphasis on potential pupil misconceptions all through the lesson plan.

Now we have discovered that immediate engineering is an artwork and a science. Having clear steerage in rubric kind for what the output must be helps us consider how we’re doing. And we’re trying ahead to listening to from academics who’re giving it a strive so we will proceed to enhance.
