Intuition

Build the mental picture first so the rest of the page has something to attach to.

Section prompt

An autonomous learning lab decides what should happen in one session. Adaptive curriculum optimization decides what should happen across many learners, many sessions, and many possible next activities.

That changes the problem. A good curriculum policy must ask:

what does this learner probably know right now?
which concepts are prerequisites or bottlenecks?
which task is likely to produce the most durable mastery gain?
which old concept is due for retrieval practice?
which candidate has uncertain value and deserves exploration?
which task is too risky because a prerequisite, assessment, or safety gate is weak?
how will we know whether the new policy is actually better than the old one?

The policy is not a magic recommender. It is an inspectable ranking system with a ledger. The learner should be able to ask why a task was selected. The builder should be able to audit which alternatives were rejected, whether the system explored enough, whether spacing was respected, and whether a holdout stream supports the change.

For Continuous Function, this matters because the product should not merely show beautiful explanations. It should improve the route a learner takes through concepts: when to repair, when to review, when to generate a visual lab, when to explore a new activity type, and when to hold back because the evidence is not good enough.

Math

Translate the story into symbols, assumptions, and a derivation you can inspect.

Section prompt

Equation 1 $s_t = \{(p_t(k), \sigma_t(k), r_t(k)) : k \in K\},$ Equation 2 $U(a \mid s_t, G) = \widehat{\Delta m}(a) + \lambda_s \operatorname{spacing}(a, s_t) + \lambda_x \operatorname{uncertainty}(a, s_t) - \lambda_d \operatorname{difficulty}(a) - \lambda_r \operatorname{risk}(a) - \lambda_g \operatorname{prereq\_gap}(a, G, s_t).$

Let the learner state at time $t$ be a vector

s_t = \{(p_t(k), \sigma_t(k), r_t(k)) : k \in K\},

where $p_t(k)$ is estimated mastery for concept $k$ , $\sigma_t(k)$ is uncertainty, and $r_t(k)$ is recency since a successful recall.

For a candidate activity $a$ , define a compact utility score:

U(a \mid s_t, G) = \widehat{\Delta m}(a) + \lambda_s \operatorname{spacing}(a, s_t) + \lambda_x \operatorname{uncertainty}(a, s_t) - \lambda_d \operatorname{difficulty}(a) - \lambda_r \operatorname{risk}(a) - \lambda_g \operatorname{prereq\_gap}(a, G, s_t).

The selected activity is

a_t = \arg\max_{a \in A_t} U(a \mid s_t, G)

unless a guardrail blocks it.

Exploration can be represented as an upper-confidence bonus:

U_{\text{explore}}(a) = \widehat{\Delta m}(a) + \beta \sigma(a).

Spacing can be represented as a due score:

\operatorname{spacing}(k) = \mathbf 1[t - t_{\text{last recall}}(k) > \Delta_k].

Evaluation should not use the same learner stream that trained the policy. With logged propensities $q(a_i \mid x_i)$ and a candidate policy $\pi$ , an inverse-propensity estimate has the shape

\widehat V(\pi) = \frac{1}{n} \sum_{i=1}^n \frac{\mathbf 1[\pi(x_i)=a_i] r_i}{q(a_i \mid x_i)}.

The formula is not a deployment certificate. It is a reminder that policy improvement needs logged context, action, propensity, reward, and a separate evaluation lane.

Code

Keep the implementation aligned with the notation so the algorithm is legible.

Section prompt

    {

    "uncertainty": 0.35,
    "difficulty": 0.25,
    "risk": 0.70,
    "prereq_gap": 0.90,
}

def utility(task):
    return (
        task["gain"]
        + weights["spacing"] * task["spacing"]
        + weights["uncertainty"] * task["uncertainty"]
        - weights["difficulty"] * task["difficulty"]
        - weights["risk"] * task["risk"]
        - weights["prereq_gap"] * task["prereq_gap"]
    )

ranked = sorted(tasks, key=utility, reverse=True)
print(ranked[0]["name"], round(utility(ranked[0]), 3))

The witness chooses retrieval review because spacing is due and risk is low. If a prerequisite gap were active, the policy would hold back even if a new visual lab had a larger raw gain estimate.

Interactive Demo

Use direct manipulation to connect the explanation to a moving system.

Section prompt

Use the policy lab to predict the curriculum move before the proof unlocks:

Objective: decide whether the policy should optimize mastery gain, spacing, exploration, or safety.
Task ranking: decide which candidate should win the next-task slot.
Exploration: decide whether uncertainty deserves an exploration budget.
Evaluation: decide whether the policy can be trusted or needs holdout evidence.

Before reveal, exact task IDs, utility scores, learner-state estimates, exploration budget, selected task, guardrail reason, and holdout estimate stay locked. After reveal, inspect the policy audit and ask whether the selected move is justified by the evidence.
